Resumen

One important phase in software development process is to create a design model of the system which follows all the architectural rules. Often the architectural rules are defined by the system architect and the system model is designed by the system designer. The architect defines the rules in a text file where no standard or pattern is followed. Therefore, there is always the risk of violating the architectural rules by the designer. So manual reviews on the system model should be done by the architect to ensure the system model is valid.In order to remove this manual checking which can be erroneous and time consuming ArCon (Architecture Conformance Checker) was developed by Combitech AB. ArCon is a tool which lets the architect define the architectural rules in the format of UML (Unified Modeling Language) models where the elements of the model have different meaning than the standard UML. ArCon can read this model and extract architectural rules from it and check the system model against those rules and then print all the rule violations.ArCon is an open source tool i.e. free for everyone to download and use. Currently, it supports Papyrus as the UML modeling tool. Papyrus is integrated to Eclipse platform and is a general purpose modeling tool. It supports users with all types of UML diagrams and elements.The idea for this thesis work was to implement a new feature for ArCon in order to facilitate the design process for system designers. The feature should provide the system designers only those types of elements which they are permitted to add to a specific fraction of the system model. The list of permitted element types should be extracted from the architecture model where all the architectural rules are defined in advance. This new support in ArCon was named Domain Specific Modeling (DSM) support.To evaluate the effect of DSM support on the system designers performance a few test sessions, called usability tests, were performed. The participants in the test sessions were a representative sample of software designers. After analyzing the data collected from the test sessions, the pros and cons of the new support were discovered. Furthermore, a few new ideas for enhancing DSM support were generated.

Resumen

Requirements are a key aspect of software development. Requirements are also related with other software artefacts including designs, test cases and documentation. These artefacts are often captured with specialized models. However, many tools lack support for traceability relationships between requirements artefacts and model artefacts, leading to analysis issues. To establish traceability between models and other types of requirements artefacts, this thesis proposes a new Domain-Specific Language (DSL) for describing the concepts of a modeling language that would be intended to be traced using a Requirements Management System (RMS), with tool support handling the evolution of models and of their traceability links. In the first part of this thesis, the syntax and metamodel of the Model Traceability DSL (MT-DSL) are defined, together with an editor implemented using Xtext. In the second part of the thesis, a library of import and maintenance functions is generated automatically (using Xtend) from model traceability descriptions written using MT-DSL. The target language for this library is the DOORS eXtension Language (DXL), the scripting language of a leading commercial RMS with traceability support, namely IBM Rational DOORS. The implementation has been tested successfully for importing and evolution scenarios with two different modeling languages (User Requirements Notation and Finite State Machines). This work hence contributes a reliable mechanism to define and support traceability between requirements and models.

Resumen

Resources Events Agents (REA) ontology is a profound business modeling ontology that was developed to define the architecture of accounting information systems. Nevertheless, REA did not manage to get the same attention as other business modeling ontologies. One reason of such abandon is the absence of a meaningful visual notation for the ontology, which has resulted in an abstruse ontology to non-academic audience. Another reason for this abandon is the fact that REA does not have a standard formal representation. This has resulted in a humble amount of researches which have focused on defining meta-models of the ontology while neglecting the wider purpose of REA-based information systems development. Consequently, the ontology was deviated away from its original purpose, and rather used in business schools. To solve the aforementioned issues, this research presents a Model Driven Development (MDD) technique in the form of a REA-based Domain Specific Visual Language (DSVL) that is implemented within a modeling and code generation editor. This effort was taken in order to answer the question of “How would a REA-DSVL based tool make the REA ontology implementable in the domain of information systems development?” In order to answer the research question, a design science methodology (DSRM) was implemented as the structure of this research. The DSRM was chosen because this research aims to develop three main artifacts. These are; a meta-model of REA, a visual notation of REA, and a REA-DSVL-based modeling and code generation tool. The first phase of the DSRM was to identify the problems which were mentioned earlier, followed by the requirements identification phase which drew the outline of the; meta-model, the visual notation, and the tool. After that, the development phase was conducted in order to develop the aforementioned artifacts. The editor was then demonstrated using a case study of a local company in Stockholm-Sweden. Finally, the resulted artifacts were evaluated based on the collected requirements and the results from the case study. Based on the analyses of the artifacts and the case study, this research was concluded with the result that a REA-based DSVL tool can help in boosting the planning and analysis phases of the software development lifecycle (SDLC). This is achieved by automating some of the conventional software planning and design tasks, which would lead to more accurate systems’ designs; thus, minimizing the time of the planning and design phases. And it can be achieved by abstracting the direct logic of REA through providing functionalities that help users from different backgrounds (academic and professional) to embrace a business modeling editor rather than an ontology; thus, attracting a wider users base for implementing REA.

Resumen

La conception d’un langage de modélisation pour domaine spécifique (DSML) implique la conception d’un outillage dédié qui met en oeuvre des fonctionnalités de traitement et d’analyse pour ce langage. Dans bien des cas, les fonctionnalités à mettre en oeuvre existent déjà , mais elles s’appliquent à des portions ou à des variantes du DSML que le concepteur manipule. Réutiliser ces fonctionnalités existantes est un moyen de simplifier la production de l’outillage d’un nouveau DSML. La réutilisation implique que les données du DSML soient adaptées afin de les rendre valides du point de vue de la fonctionnalité à réutiliser. Si l’adaptation est faite et les données sont placées dans le contexte de la fonctionnalité, elle peut être réutilisée. Le résultat produit par l’outil reste dans le contexte de l’outil et il doit être adapté afin de le placer dans le contexte du DSML (migration inverse). Dans ce cadre, la réutilisation n’a de sens que si les deux adaptations de données sont peu coûteuses. L’objectif de cette thèse est de proposer un mécanisme qui intègre la migration, la réutilisation et la migration inverse. La principale contribution est une approche qui facilite la réutilisation de fonctionnalités existantes via des migrations de modèles. Cette approche facilite la production de l’outillage d’un DSML. Elle permet de faire des migrations réversibles entre deux DSMLs sémantiquement proches. L’utilisateur est guidé lors du processus de réutilisation pour fournir rapidement l’outillage complet et efficace d’un DSML. L’approche a été formalisée et appliquée à un DSML (Orcc) dans le contexte des MPSoC
Designers of domain specific modeling languages (DSMLs) must provide all the tooling of these languages. In many cases, the features to be developped already exist, but it applies to portions or variants of the DSML.One way to simplify the implementation of these features is by reusing the existing functionalities. Reuse means that DSML data must be adapted to be valid according to the functionality to be reused. If the adaptation is done and the data are placed in the context of the functionality, it can be reused. The result produced by the tool remains in the context of the tool and it must be adapted to be placed in the context of the DSML (reverse migration).In this context, reuse makes sense only if the migration and the reverse migration are not very expensive. The main objective of this thesis is to provide a mechanism to integrate the migration, the reuse and the reversemigration and apply them efficiently. The main contribution is an approach that facilitates the reuse of existing functionalities by means of model migrations. This approach facilitates the production of the tooling for a DSML. It allows reversible migration between two DSMLs semantically close. The user is guided during the ruse process to quickly provide the tooling of his DSML.The approach has been formalised et applied to a DSML (Orcc) in the context of the MPSoC

Resumen

Viena iš naujausių sistemų kūrimo metodikų – sričiai orientuotas modeliavimas (angl. domain specific modeling). Ji paremta sričiai orientuotos kalbos kūrimu ir jos panaudojimu sistemos kūrimui. Ši metodika leidžia sistemos kūrimui naudoti sąvokas, artimas probleminei sričiai, kas padidina abstrakcijos lygi projektavimo metu. Srities sąvokos aptariamos ir įvardinamos kartu su ekspertais ar paprastais darbuotojais, dirbančiais analizuojamoje srityje, ir nebūtinai išmanančiais sistemų kūrimo metodus. Ši metodika leidžia sistemos projektuotojui lengviau susikalbėti su užsakovais, nes modeliuose figūruojančios sąvokos yra užsakovui suprantamos ir aiškios.
Domain Specific Modeling is a software engineering methodology for designing and developing information systems. It involves systematic use of a graphical domain specific language (DSL) to represent the various facets of a system. DSM languages tend to support higher-level abstractions than general purpose modeling languages, so they require less effort and fewer low-level details to specify a given system which is very important nowadays, when the functionality of information system must be maximized with minimum development time and cost. This paper compares usage of DSL for information system development with other two, most often used methodologies for this purpose: MDA and usage of UML. It gives basic advantages and disadvantages of DSL and DSM usage, describes differences of DSL (DSM), UML and MDA. This paper also describes usage of DSM methodology (creating DSL and using it for software development) for creating information system. It covers main steps of creation process’s: describing the domain concepts, describing the artifacts that are planning for the DSL, building domain model, building the designer for DSL, building the artifact generator, implementing validations and constraints, testing and deploying the DSL.

Resumen

Domain specific Modeling Languages (DSMLs) are increasingly used at the early phases in the development of complex systems, in particular, for safety critical systems. The goal is to be able to reason early in the development on these models and, in particular, to fulfill verification and validation activities (V and V). A widely used technique is the exhaustive behavioral model verification using model-checking by providing a translational semantics to build a formal model from DSML conforming models in order to reuse powerful tools available for this formal domain. Defining a translational semantics, expressing formal properties to be assessed and analysing such verification results require such an expertise in formal methods that it restricts their adoption and may discourage the designers. It is thus necessary to build for each DSML, a toolchain which hides formal aspects for DSML end-users. The goal of this thesis consists in easing the development of such verification toolchains. Our contribution includes 1) expressing behavioral properties in the DSML level by relying on TOCL (Temporal Object Constraint Language), a temporal extension of OCL; 2) An automated transformation of these properties on formal properties while reusing the key elements of the translational semantics; 3) the feedback of verification results thanks to a higher-order transformation and a language which defines mappings between DSML and formal levels; 4) the associated process implementation. Our approach was validated by the experimentation on a subset of the development process modeling language SPEM, and on Ladder Diagram language used to specify programmable logic controllers (PLCs), and by the integration of a formal intermediate language (FIACRE) in the verification toolchain. This last point allows to reduce the semantic gap between DSMLs and formal domains.

Resumen

Esta tese apresenta um processo para a criação de um catálogo de modelos de computação para apoiar o design de DSMLs, e a primeira versão do catálogo, com atributos que ajudam a selecionar os modelos de computação mais adequados para cada desenvolvimento de DSML, e as características dos sistemas de software para os quais esses modelos de computação são mais adequados. O contexto de aplicação desse catálogo é o Model-Driven Development (MDD desenvolvimento dirigido por modelos) a abordagem em que o desenvolvimento de software é baseado em modelos gráficos que são posteriormente traduzidos (transformados) em modelos de nível mais baixo e, no final, em código de linguagens de programação, tais como Java ou C#. A aplicação do processo gerou uma versão inicial do catálogo com os seguintes modelos de computação: diagramas BPMN, diagramas de classe da UML e regras de negócio. Visa-se contribuir para popularizar a abordagem de MDD com base em DSMLs e, em particular, a elaboração do design das DSMLs a partir de modelos de domínio, para o que o uso do catálogo efetivamente contribui.
This thesis presents a process for the creation of a catalog of models of computation to support the design of Domain-Specific Modeling Languages (DSMLs), and the first version of the catalog, which comprises attributes that aim to help the selection of the most suitable models of computation for each DSML development, and characteristics of software systems for which these models of computation are more appropriate. The context for the use of the catalog is the Model-Driven Development (MDD) - the approach where software development is based on graphical models that are subsequently translated (transformed) into lower-level models and, in the end, in source code in programming languages, such as Java or C #. The process was applied to generate an initial version of the catalog with the following models of computation: BPMN diagrams, UML class diagrams and business rules. It aims to contribute to popularize the MDD approach based in DSMLs, and in particular, the development of the DSMLs design from domain models, for which the use of the catalog effectively contributes.

Resumen

Les techniques dynamiques de vérification et validation (V&V) de modèles sont nécessaires pour assurer la qualité des modèles exécutables. La plupart de ces techniques reposent sur la concept de trace d'exécution, une séquence contenant un ensemble d'informations sur une exécution. Par conséquent, pour permettre la V&V dynamique de modèles exécutables conformes à n'importe quel langage de modélisation dédié exécutable (LMDx), il est crucial de fournir des outils pour construire et manipuler toutes sortes de traces d'exécution. À cet effet, nous proposons d'abord une approche de clonage efficace de modèles afin de pouvoir construire des traces d'exécution génériques à base de clones. À l'aide d'un générateur aléatoire de métamodèles, nous montrons que cette approche passe à l'échelle avec seulement un léger surcoût lors de la manipulation de clones. Nous présentons ensuite une approche générative pour définir des métamodèles dédiés et multidimensionnels pour représenter des traces d'exécution, qui consiste à créer la structure de données spécifique aux traces d'exécution d'un LMDx donné. Ainsi, les traces d'exécution de modèles conformes à ce LMDx peuvent être capturées et manipulées efficacement de manière dédiée et à l'aide de différentes dimensions. Nous appliquons cette approche à deux techniques de V&V dynamiques existantes, à savoir la différentiation sémantique et le débogage omniscient. Nous montrons qu'un tel métamodèle de traces d'exécution généré fournit une bonne facilité d'usage et un bon passage à l'échelle pour la V&V dynamique au plus tôt pour n'importe quel LMDx. Nous avons intégré notre travail au sein du GEMOC Studio, un environnement de définition de langages et de modélisation issu de l'initiative internationale du même nom
Dynamic verification and validation (V&V) techniques are required to ensure the correctness of executable models. Most of these techniques rely on the concept of execution trace, which is a sequence containing information about an execution. Therefore, to enable dynamic V&V of executable models conforming to any executable domain-specific modeling language (xDSML), it is crucial to provide efficient facilities to construct and manipulate all kinds of execution traces. To that effect, we first propose a scalable model cloning approach to conveniently construct generic execution traces using model clones. Using a random metamodel generator, we show that this approach is scalable in memory with little manipulation overhead. We then present a generative approach to define multidimensional and domain-specific execution trace metamodels, which consists in creating the execution trace data structure specific to an xDSML. Thereby, execution traces of models conforming to this xDSML can be efficiently captured and manipulated in a domain-specific way. We apply this approach to two existing dynamic V&V techniques, namely semantic differencing and omniscient debugging. We show that such a generated execution trace metamodel provides good usability and scalability for dynamic early V&V support for any xDSML. Our work have been implemented and integrated within the GEMOC Studio, which is a language and modeling workbench resulting from the eponym international initiative

Resumen

Today it is realized by industry that automation of software development leads to increased productivity, maintainability and higher quality. Model-Driven Development (MDD) aims to replace manual software development methods by automated methods using Domain-Specific Languages (DSLs) to express domain concepts effectively. Main actors in software industry, Microsoft and IBM have recognized the need to provide technologies and tools to allow building DSLs to support MDD. On the one hand, Microsoft is building DSL Tools integrated in Visual Studio 2005; on the other hand IBM is contributing to the development of Eclipse Modeling Frameworks (EMF/GEF/GMF), both tools aim to make development and deployment of DSLs easier. Software practitioners seek for guidelines regarding how to adopt these tools. In this thesis, the author presents the current state-of-the-art in MDD standards and Domain-Specific Modeling (DSM). Furthermore, the author presents current state-of-the-tools for DSM and performs a comparison of Microsoft DSL Tools and Eclipse EMF/GEF/GMF Frameworks based on a set of evaluation criteria. For the purpose of comparison the author developed two DSL designers (one by using each DSM tool). Based on the experiences gained in development of these DSL designers, the author prepared guidelines regarding how to adopt these tools to existing development environments as well as their advantages and drawbacks.

Resumen

Enterprise portals are comprehensive solutions that enable centralized access to information and employees. They also support the business processes taking place in companies. The diversity of functionality offered by enterprise portals is the source of the complexity of the manufacturing process of such applications. Domain-Specific Languages (DSL) are a novel approach to solving problems associated with the software development. By limiting the possibilities of expression to the concepts related to a specific area Domain-Specific Languages are more focused on solving specific problems. The subject of this thesis is DSL SharePoint – Domain-Specific Language which supports the production of enterprise portals on Microsoft SharePoint platform. Language was developed with respect to the newest achievements in area of building DSLs. By applying the language in the industry, it was possible to verify the hypothesis that its usage positively affects the quality of software products. To this end, the quality model was built, and products made with the support of language have been compared to those developed in the traditional manner.

Resumen

Context. A clear software process definition is important because it can help developers to share a common understanding and improve the development effectiveness. However, if the misconceptions or misunderstandings are introduced to the team during the process definition, it will bring numerous uncertain problems to the projects and reduce the productivity. Scrum is one of the most popular Agile development processes. It has been frequently used in software development. But the misunderstanding of usage of the Scrum method always leads to situations where teams cannot achieve the hyper-productivity even failure. Therefore, introducing a reasonable graphical language for describing the Scrum process may help learners to gain a correct and common understanding of the Scrum method. Objectives. In this study, we introduce a graphical Domain Specific Language for modeling the Scrum process and specific Scrum projects. Further, we evaluated the proposed language to figure out if and how this language can help developers learn Scrum method and understand the specific Scrum projects. For the first, we decide to extract the essential elements and their relative relationships of the Scrum process, and based on that, we define and specify the graphical language. After that, we evaluate the proposed graphical language to validate whether this language can be considered as useful to help developers to learn Scrum method and understand the specific Scrum projects. Methods. In order to define the graphical language, we studied and reviewed the literature to extract the essential elements and their relationships for describing the Scrum process. Based on that, we defined and specified the graphical DSL. With the aim of evaluating the proposed graphical language, we performed the experiment and survey method. This experiment was conducted in an educational environment. The subjects were selected from the undergraduate and master students. At the same time, we carried out a survey to capture the developers‘ opinions and suggestions towards the proposed language in order to validate its feasibility. Results. By studying the literature, we listed and specified the essential elements for describing the Scrum process. By executing the experiment, we evaluated the efficiency and effectiveness of learning Scrum in using the proposed language and the natural language. The result indicates that the graphical language is better than the natural language in training Scrum method and understanding specific Scrum projects. The result shows that the proposed language improved the understandability of the Scrum process and specific Scrum projects by more than 30%. We also performed a survey to investigate the potential use of the proposed graphical DSL in industry. The Survey results show that participants think the proposed graphical language can help them to better understand the Scrum method and specific Scrum projects. Moreover, we noticed that the developers who have less Scrum development experience show more interests in this proposed graphical language. Conclusions. To conclude, the obtained results of this study indicate that a graphical DSL can improve the understandability of Scrum method and specific Scrum projects. Especially in managing the specific Scrum project, subjects can easily understand and capture the detailed information of the project described in the proposed language. This study also specified the merits and demerits of using the graphical language and textual language in describing the Scrum process. From the survey, the result indicates that the proposed graphical language is able to help developers to understand Scrum method and specific Scrum projects in industry. Participants of this survey show positive opinion toward the proposed graphical language. However, it is still a rather long way to applying such a graphical language in Scrum projects development because companies have to consider the extra learning effort of the graphical DSL.

Performance is a fundamental quality of software systems. Performance testing is a technique able to reveal system bottlenecks and/or lack of scalability of the up-and-running environment. However, usually the software development cycle does not apply this effort on the early development phases, thereby resulting in a weak elicitation process of performance requirements and difficulties for the performance team to integrate them into the project scope. Model-Based Testing (MBT) is an approach to automate the generation of test artifacts from the system models. By doing that, communication is improved among teams, given that the test information is aggregated in the system models since the early stages aiming to automate the testing process. The main contribution of this thesis is to propose a Domain-Specific Language (DSL) for modeling performance testing in Web applications. The language is called Canopus, in which a graphical model and a natural language are proposed to support performance modeling and automatic generation of test scenarios and scripts. Furthermore, this work provides an example of use and an industrial case study to demonstrate the use of Canopus. Based on the results obtained from these studies, we can infer that Canopus can be considered a valid DSL for modeling performance testing. Our motivation to perform this study was to investigate whether a DSL for modeling performance testing can improve quality, cost, and efficiency of performance testing. Therefore, we also carried out a controlled empirical experiment to evaluate the effort (time spent), when comparing Canopus with another industrial approach - UML. Our results indicate that, for performance modeling, effort using Canopus was lower than using UML. Our statistical analysis showed that the results were valid, i.e., that to design performance testing models using Canopus is better than using UML.
Desempenho ? uma qualidade fundamental de sistemas de software. Teste de desempenho ? uma t?cnica capaz de revelar gargalos do sistema na escalabilidade do ambiente de produ??o. No entanto, na maior parte do ciclo de desenvolvimento de software, n?o se aplica este tipo de teste nos seus ciclos iniciais. Deste modo, isto resulta em um fraco processo de elicita??o dos requisitos e dificuldades da equipe em integrar suas atividades ao escopo do projeto. Assim, o teste baseado em modelos ? uma abordagem de teste para automatizar a gera??o de artefatos de teste com base em modelos. Ao fazer isto, permite melhorar a comunica??o da equipe, uma vez que a informa??o de teste ? agregada aos modelos desde as fases iniciais do processo de teste, facilitando assim sua automatiza??o. A principal contribui??o desta tese ? propor uma linguagem espec?fica de dom?nio (Domain-Specific Language - DSL) para modelagem de teste de desempenho em aplica??es Web. A DSL proposta ? chamada Canopus, na qual um modelo gr?fico e uma linguagem semi-natural s?o propostos para apoiar a modelagem de desempenho e gera??o autom?tica de cen?rios e scripts de teste. Al?m disto, apresenta-se um exemplo de uso bem como um estudo de caso realizado na ind?stria para demonstrar o uso da Canopus. Com base nos resultados obtidos, infere-se que a Canopus pode ser considerada uma DSL v?lida para modelagem do teste de desempenho. A motiva??o para realiza??o deste estudo foi investigar se uma DSL para modelagem do teste de desempenho pode melhorar a qualidade, custo e efici?ncia do teste de desempenho. Assim, tamb?m foi realizado um experimento controlado com o objetivo de avaliar o esfor?o (tempo), quando comparado Canopus com outra abordagem industrial - UML. Os resultados obtidos indicam que, estatisticamente, para a modelagem de desempenho usando Canopus o esfor?o foi menor e melhor do que usando UML.

Resumen

Les appareils modernes sont constitués de plusieurs sous-systèmes de différentes sortes qui communiquent et interagissent. L'hétérogénéité de ces sous-systèmes et leurs interactions complexes rendent très délicate leur développement. L'approche d'ingénierie dirigée par les modèles apporte une solution en permettant l'expression de nombreux modèles structurels et comportementaux de natures très diverses. Dans ce contexte, il est nécessaire de construire un modèle unique qui intègre ces différents modèles afin d'y appliquer des méthodes de validation et de vérification pour permettre aux ingénieurs système de comprendre et de valider un comportement global. Cependant, la coordination manuelle des différents modèles qui composent le système est une opération source d'erreurs et les approches automatiques proposent des patrons de coordination ad-hoc pour certaines paires de langages. Dans ces approches, le patron de coordination est souvent encapsulé dans un outil dont il est difficile d'extraire les liens avec le système global. Cette thèse propose le Behavioral Coordination Operator Language (BCOoL), un langage dédié à la spécification de patrons de coordination entre des langages à partir de la définition d'opérateurs de coordination. Ces opérateurs sont employés afin d'automatiser la coordination de modèles exprimés dans ces langages. BCOoL est implémenté comme une suite de plugins qui s'appuient sur l'Eclipse Modeling Framework et présente ainsi un environnement complet pour l'exécution et la vérification de différents modèles coordonnés
Modern devices embed several subsystems with different characteristics that communicate and interact in many ways. This makes its development complex since a designer has to deal with the heterogeneity of each subsystem but also with the interaction between them. To tackle the development of complex systems, Model Driven Engineering promotes the use of various, possibly heterogeneous, structural and behavioral models. In this context, the coordination of behavioral models to produce a single integrated model is necessary to provide support for validation and verification. It allows system designers to understand and validate the global and emerging behavior of the system. However, the manual coordination of models is tedious and error-prone, and current approaches to automate the coordination are bound to a fixed set of coordination patterns. Moreover, they encode the pattern into a tool thus limiting reasoning on the global system behavior. In this thesis, we propose a Behavioral Coordination Operator Language (B-COoL) to reify coordination patterns between specific domains by using coordination operators between the Domain-Specific Modeling Languages used in these domains. Those operators are then used to automate the coordination of models conforming to these languages. B-COoL is implemented as plugins for the Eclipse Modeling Framework thus providing a complete environment to execute and verify coordinated models. We illustrate the use of B-COoL with the definition of coordination operators between timed finite state machines and activity diagrams. We then use these operators to coordinate and execute the heterogeneous models of a surveillance camera system

Resumen

Enterprise data systems are continuously growing in complexity and size. The attack area of these systems has increased and introduced new vulnerabilities a potential adversary could exploit. Evaluating cyber security in enterprise IT infrastructure is difficult and expensive. Recently, a new threat modeling language was proposed for enterprise systems based on the MITRE Enterprise ATT&CK Matrix, namely enterpriseLang. This language is a domain- specific language built on the Meta Attack Language (MAL) framework. The purpose of enterpriseLang is to enable a simplified and cost- effective environment for enterprises to evaluate the security of their systems without disturbing the data flow of the actual system. However, how can we be sure that enterpriseLang is correct and effective enough to be used in practice? The language needs to be thoroughly validated to be used by companies for cyber security evaluation of enterprise systems. We have validated enterpriseLang by implementing it to model and simulate three real- world cyber attacks against, Equifax, National Health Service (NHS) and Garmin. The validation method was mainly based on the evaluation of two specific issues. Based on our results we concluded that we consider enterpriseLang to be correct and effective enough to be used in practice. On the contrary, we identified some aspects of the language that should be improved.
Företags datasystem växer kontinuerligt i komplexitet och storlek. Attackarean för dessa system har därmed ökat och infört nya sårbarheter som en potentiell angripare kan utnyttja. Att utvärdera cybersäkerhet i företags IT- infrastruktur är svårt och kostsamt. Nyligen föreslogs ett nytt språk för hotmodellering av företagssystem baserat på MITRE Enterprise ATT&CK matrix, nämligen enterpriseLang. Detta språk är ett domänspecifikt språk byggt på MAL- ramverket. Syftet med enterpriseLang är att möjliggöra ett förenklat och kostnadseffektivt modelleringsverktyg för företag att utvärdera säkerheten av sina system i, utan behovet av att störa dataflödet i det faktiska systemet. Hur kan vi dock vara säkra på att enterpriseLang är korrekt och tillräckligt effektivt för att användas i praktiken? Språket måste valideras grundligt för att kunna användas för evaluering av cybersäkerhet i företagssystem. Vi har validerat enterpriseLang genom att använda språket till att modellera och simulera tre verkliga cyberattacker mot Equifax, National Health Service och Garmin. Valideringsmetoden grundades i evalueringen av två huvudfrågor. Baserat på vårt resultat drog vi slutsatsen att vi anser enterpriseLang som korrekt och tillräckligt effektivt för att användas i praktiken. Däremot, identifierade vi några aspekter inom språket som bör förbättras.

Resumen

With the advent of exascale architectures maximizing performance while maintaining energy consumption within reasonable limits has become one of the most critical design constraints. This constraint is particularly significant in light of the power budget of 20 MWatts set by the U.S. Department of Energy for exascale supercomputing facilities. Therefore, understanding an application's characteristics, execution pattern, energy footprint, and the interactions of such aspects is critical to improving the application's performance as well as its utilization of the underlying resources. With conventional methods of analyzing performance and energy consumption trends scientists are forced to limit themselves to a manageable number of design parameters. While these modeling techniques have catered to the needs of current high-performance computing systems, the complexity and scale of exascale systems demands that large-scale design-space-exploration techniques are developed to enable comprehensive analysis and evaluations. In this dissertation we present research on performance and energy modeling of current high performance computing and future exascale systems. Our thesis is focused on the design space exploration of current and future architectures, in terms of their reconfigurability, application's sensitivity to hardware characteristics (e.g., system clock, memory bandwidth), application's execution patterns, application's communication behavior, and utilization of resources. Our research is aimed at understanding the methods by which we may maximize performance of exascale systems, minimize energy consumption, and understand the trade offs between the two. We use analytical, statistical, and machine-learning approaches to develop accurate, portable and scalable performance and energy models. We develop application and machine abstractions using Aspen (a domain specific language) to implement and evaluate our modeling techniques. As part of our research we develop and evaluate system-level performance and energy-consumption models that form part of an automated modeling framework, which analyzes application signatures to evaluate sensitivity of reconfigurable hardware components for candidate exascale proxy applications. We also develop statistical and machine-learning based models of the application's execution patterns on heterogeneous platforms. We also propose a communication and computation modeling and mapping framework for exascale proxy architectures and evaluate the framework for an exascale proxy application. These models serve as external and internal extensions to Aspen, which enable proxy exascale architecture implementations and thus facilitate design space exploration of exascale systems.

Resumen

La tesi ha lo scopo di esplorare la produzione di sistemi software per Embedded Systems mediante l'utilizzo di tecniche relative al mondo del Model Driven Software Development. La fase più importante dello sviluppo sarà la definizione di un Meta-Modello che caratterizza i concetti fondamentali relativi agli embedded systems. Tale modello cercherà di astrarre dalla particolare piattaforma utilizzata ed individuare quali astrazioni caratterizzano il mondo degli embedded systems in generale. Tale meta-modello sarà quindi di tipo platform-independent. Per la generazione automatica di codice è stata adottata una piattaforma di riferimento, cioè Arduino. Arduino è un sistema embedded che si sta sempre più affermando perché coniuga un buon livello di performance ed un prezzo relativamente basso. Tale piattaforma permette lo sviluppo di sistemi special purpose che utilizzano sensori ed attuatori di vario genere, facilmente connessi ai pin messi a disposizione. Il meta-modello definito è un'istanza del meta-metamodello MOF, definito formalmente dall'organizzazione OMG. Questo permette allo sviluppatore di pensare ad un sistema sotto forma di modello, istanza del meta-modello definito. Un meta-modello può essere considerato anche come la sintassi astratta di un linguaggio, quindi può essere definito da un insieme di regole EBNF. La tecnologia utilizzata per la definizione del meta-modello è stata Xtext: un framework che permette la scrittura di regole EBNF e che genera automaticamente il modello Ecore associato al meta-modello definito. Ecore è l'implementazione di EMOF in ambiente Eclipse. Xtext genera inoltre dei plugin che permettono di avere un editor guidato dalla sintassi, definita nel meta-modello. La generazione automatica di codice è stata realizzata usando il linguaggio Xtend2. Tale linguaggio permette di esplorare l'Abstract Syntax Tree generato dalla traduzione del modello in Ecore e di generare tutti i file di codice necessari. Il codice generato fornisce praticamente tutta la schematic part dell'applicazione, mentre lascia all'application designer lo sviluppo della business logic. Dopo la definizione del meta-modello di un sistema embedded, il livello di astrazione è stato spostato più in alto, andando verso la definizione della parte di meta-modello relativa all'interazione di un sistema embedded con altri sistemi. Ci si è quindi spostati verso un ottica di Sistema, inteso come insieme di sistemi concentrati che interagiscono. Tale difinizione viene fatta dal punto di vista del sistema concentrato di cui si sta definendo il modello. Nella tesi viene inoltre introdotto un caso di studio che, anche se abbastanza semplice, fornisce un esempio ed un tutorial allo sviluppo di applicazioni mediante l'uso del meta-modello. Ci permette inoltre di notare come il compito dell'application designer diventi piuttosto semplice ed immediato, sempre se basato su una buona analisi del problema. I risultati ottenuti sono stati di buona qualità ed il meta-modello viene tradotto in codice che funziona correttamente.

Resumen

Ce travail de recherche porte sur la spécification et l'opérationnalisation des scénarios pédagogiques sur les plateformes de formation à distance dans une perspective d'ingénierie et de réingénierie des EIAH (Environnements Informatique pour l'Apprentissage Humain). En se situant dans une approche centrée plateformes, nous supposons que les plateformes disposent de leur propre paradigme de conception. Pour cela, nous proposons aux développeurs et à la communauté de développement des plateformes un processus spécifique d'identification et d'explicitation du langage de conception pédagogique des plateformes de formation par le biais d'un métamodèle. Nous exploitons l'approche outillée Domain-Specific Modeling comme cadre pratique pour le développement de langages et d'outils de conception graphiques basés sur le métamodèle du langage de conception pédagogique. Afin de répondre à des besoins récurrents d'opérationnalisation de scénarios pédagogiques, nous utilisons également ce métamodèle pour la spécification des modules d'import/export intégrés au sein des plateformes. Ces modules permettent d'opérationnaliser les scénarios conformes au langage identifié et également d'exporter les scénarios existants sur les plateformes afin de permettre leur adaptation par les outils développés. Nous avons expérimenté nos propositions théoriques sur deux plateformes de formation Moodle et Ganesha. Enfin, nous avons vérifié la cohérence de notre approche par la mise à l'essai des outils développés. Par le biais de notre approche, nous favorisons une opérationnalisation de ces scénarios sans pertes d'information ni de sémantique.

Resumen

Die Anwendung von Methodiken und Technologien aus dem Bereich der Softwaretechnik auf den Bereich der Umweltmodellierung ist eine gemeinhin akzeptierte Vorgehensweise. Im Rahmen der "modellgetriebenen Entwicklung"(MDE, model-driven engineering) werden Technologien entwickelt, die darauf abzielen, Softwaresysteme vorwiegend auf Basis von im Vergleich zu Programmquelltexten relativ abstrakten Modellen zu entwickeln. Ein wesentlicher Bestandteil von MDE sind Techniken zur effizienten Entwicklung von "domänenspezifischen Sprachen"( DSL, domain-specific language), die auf Sprachmetamodellen beruhen. Die vorliegende Arbeit zeigt, wie modellgetriebene Entwicklung, und insbesondere die metamodellbasierte Beschreibung von DSLs, darüber hinaus Aspekte der Pragmatik unterstützen kann, deren Relevanz im erkenntnistheoretischen und kognitiven Hintergrund wissenschaftlichen Forschens begründet wird. Hierzu wird vor dem Hintergrund der Erkenntnisse des "modellbasierten Forschens"(model-based science und model-based reasoning) gezeigt, wie insbesondere durch Metamodelle beschriebene DSLs Möglichkeiten bieten, entsprechende pragmatische Aspekte besonders zu berücksichtigen, indem sie als Werkzeug zur Erkenntnisgewinnung aufgefasst werden. Dies ist v.a. im Kontext großer Unsicherheiten, wie sie für weite Teile der Umweltmodellierung charakterisierend sind, von grundsätzlicher Bedeutung. Die Formulierung eines sprachzentrierten Ansatzes (LCA, language-centered approach) für die Werkzeugunterstützung konkretisiert die genannten Aspekte und bildet die Basis für eine beispielhafte Implementierung eines Werkzeuges mit einer DSL für die Beschreibung von Zellulären Automaten (ZA) für die Umweltmodellierung. Anwendungsfälle belegen die Verwendbarkeit von ECAL und der entsprechenden metamodellbasierten Werkzeugimplementierung.
The application of methods and technologies of software engineering to environmental modeling and simulation (EMS) is common, since both areas share basic issues of software development and digital simulation. Recent developments within the context of "Model-driven Engineering" (MDE) aim at supporting the development of software systems at the base of relatively abstract models as opposed to programming language code. A basic ingredient of MDE is the development of methods that allow the efficient development of "domain-specific languages" (DSL), in particular at the base of language metamodels. This thesis shows how MDE and language metamodeling in particular, may support pragmatic aspects that reflect epistemic and cognitive aspects of scientific investigations. For this, DSLs and language metamodeling in particular are set into the context of "model-based science" and "model-based reasoning". It is shown that the specific properties of metamodel-based DSLs may be used to support those properties, in particular transparency, which are of particular relevance against the background of uncertainty, that is a characterizing property of EMS. The findings are the base for the formulation of an corresponding specific metamodel- based approach for the provision of modeling tools for EMS (Language-centered Approach, LCA), which has been implemented (modeling tool ECA-EMS), including a new DSL for CA modeling for EMS (ECAL). At the base of this implementation, the applicability of this approach is shown.

Resumen

The technological advancements in the automotive industry as well as in thefield of communication technologies done the last years have transformed thevehicles to complex machines that include not only electrical and mechanicalcomponents but also a great number of electronic components. Furthermore,modern vehicles are now connected to the Wide Area Network (WAN) and inthe near future communications will also be present between the cars (Vehicleto-Vehicle, V2V) and between cars and infrastructure (Vehicle-to-Infrastructure, V2I), something that can be found as Internet of Vehicles (IoV)in the literature. The main motivations towards all the aforementioned changesin modern vehicles are of course the improvement of road safety, the higherconvenience of the passengers, the increase in the efficiency and the higher userfriendliness.On the other hand, having vehicles connected to the Internet opens them up toa new domain of interest, this no other than the domain of cyber security. Thispractically means that while previously we were only considering cyber-attackson computational systems, now we need to start thinking about it also forvehicles. This, as a result, creates a new field of research, namely the vehicularcyber security. However, this field does not only include the possible vehicularcyber-attacks and their corresponding defenses but also the modeling andsimulation of them with the use of vehicular security analysis tools, which isalso recommended by the ENISA report titled “Cyber Security and Resilienceof smart cars: Good practices and recommendations”.Building on this need for vehicular security analysis tools, this work aims tocreate and evaluate a domain-specific, probabilistic modeling and simulationlanguage for cyber-attacks on modern connected vehicles. The language will bedesigned based on the existing threat modeling and risk management toolsecuriCAD® by foreseeti AB and more specifically based on its underlyingmechanisms for describing and probabilistically evaluating the cyber threats ofthe models.The outcome/final product of this work will be the probabilistic modeling andsimulation language for connected vehicles, called vehicleLang, that will beready for future use in the securiCAD® software.
De tekniska framstegen inom fordonsindustrin såväl som inomkommunikationsteknik som gjorts de senaste åren har omvandlat fordon tillkomplexa maskiner som inte bara omfattar elektriska och mekaniskakomponenter utan också ett stort antal elektroniska komponenter. Dessutom ärmoderna fordon nu anslutna till Internet (WAN) och inom den närmasteframtiden kommer kommunikation också att etableras mellan bilarna (Vehicleto-Vehicle, V2V) och mellan bilar och infrastruktur (Vehicle-to-Infrastructure,V2I). Detta kan också kallas fordonens internet (Internet of Vehicles - IoV) ilitteraturen. De främsta motiven för alla ovannämnda förändringar i modernafordon är förstås förbättringen av trafiksäkerheten, ökad bekvämlighet förpassagerarna, ökad effektivitet och högre användarvänlighet.Å andra sidan, att ha fordon anslutna till Internet öppnar dem för en ny domän,nämligen cybersäkerhet. Då vi tidigare bara övervägde cyberattacker påtraditionella datorsystem, måste vi nu börja tänka på det även för fordon. Dettaområde omfattar emellertid inte bara de möjliga fordonsattackerna och derasmotsvarande försvar utan även modellering och simulering av dem med hjälpav verktyg för analys av fordonssäkerhet, vilket också rekommenderas avENISA-rapporten med titeln ”Cyber Security and Resilience of smart cars: Goodpractices and recommendations”.På grund av detta behov av verktyg för fordonssäkerhetsanalys syftar dettaarbete till att skapa och utvärdera ett domänspecifikt, probabilistisktmodelleringsspråk för simulering av cyberattacker på moderna anslutna fordon.Språket har utformats utifrån det befintliga hotmodellerings- ochriskhanteringsverktyget securiCAD® av foreseeti AB och mer specifikt baseratpå dess underliggande mekanismer för att beskriva och probabilistiskt utvärderamodellernas cyberhot.Resultatet/slutprodukten av detta arbete är ett probabilistisktmodelleringsspråk för uppkopplade fordon, vehicleLang.

Resumen

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico
In ubiquitous systems, due to the complexity added by the use of contextual information, the application of context aware exception handling (CAEH) techniques has many challenges and in the literature several approaches have been found to define concepts and abstractions useful for modeling CAEH. However, only one of these approaches proposes a method for specification and verification of models in the field of ubiquitous systems, which provides a tool for specifying the CAEH model using a Java API, and also generates an error report to a text file. The disadvantage of this approach is that the designer should strive to understand programming details that are irrelevant to the analysis process of the exceptional behavior of the system. Then, this work aims to propose a domain specific language for modeling CAEH, which provides abstractions and constructors that allow to express relevant concepts and make the task of designing CAEH models simpler and more intuitive. In addition, the language is integrated with the tool mentioned before that allows automatic model verification. The errors generated by the verifier are now shown directly in the source code making their identification and correction easier for the designer. In order to evaluate the language, a case study is conducted to provide evidence of its viability as an alternative to modeling CAEH.
Em sistemas ubÃquos, devido Ã complexidade inserida pela utilizaÃÃo de informaÃÃes contextuais, a aplicaÃÃo de tÃcnicas de tratamento de exceÃÃo sensÃvel ao contexto (TESC) tem sido objeto de estudo para muitos pesquisadores. Na literatura sÃo encontradas diversas abordagens que definem conceitos e abstraÃÃes Ãteis para modelagem de TESC. Entretanto, apenas uma dessas abordagens propÃe um mÃtodo para especificaÃÃo e verificaÃÃo de modelos no domÃnio de sistemas ubÃquos o qual fornece uma ferramenta para especificaÃÃo do modelo de TESC atravÃs de uma API Java, e gera ainda um relatÃrio de erros em um arquivo texto. A desvantagem dessa abordagem Ã que o projetista deve se esforÃar para entender detalhes de programaÃÃo irrelevantes ao processo de anÃlise do comportamento excepcional do sistema. Esta dissertaÃÃo tem portanto como objetivo propor uma linguagem de domÃnio especÃfico para modelagem de TESC, com o intuito de oferecer abstraÃÃes e construtores que permitem expressar conceitos pertinentes e tornar a tarefa de projetar modelos de TESC mais simples e intuitiva. AlÃm disso, a linguagem Ã integrada com a ferramenta citada anteriormente, o que permite realizar a verificaÃÃo do modelo de forma automÃtica. Os erros gerados pelo verificador sÃo mostrados agora diretamente no cÃdigo do modelo facilitando a identificaÃÃo e correÃÃo dos mesmos pelo projetista. A fim de avaliar a linguagem, um estudo de caso Ã realizado para fornecer indÃcios de sua viabilidade como alternativa para modelagem de TESC.

Cada vez mais se evidencia uma maior escassez de recursos e uma disputa por espaços físicos, em decorrência da crescente e demasiada concentração populacional nas grandes cidades. Nesse âmbito, surge a necessidade de soluções que vão de encontro à iniciativa de “Cidades Inteligentes" (Smart Cities). Essas soluções buscam centralizar o monitoramento e controle, para auxiliar no apoio à tomada de decisão. No entanto, essas fontes de TICs formam estruturas complexas e geram um grande volume de dados, que apresentam enormes desafios e oportunidades. Uma das principais ferramentas tecnológicas utilizadas nesse contexto é o Complex Event Processing (CEP), o qual pode ser considerado uma boa solução, para lidar com o aumento da disponibilidade de grandes volumes de dados, em tempo real. CEPs realizam captação de eventos de maneira simplificada, utilizando linguagem de expressão, para definir e executar regras de processamento. No entanto, apesar da eficiência comprovada dessas ferramentas, o fato das regras serem expressas em baixo nível, torna o seu uso exclusivo para usuários especialistas, dificultando a criação de soluções. Com intuito de diminuir a complexidade das ferramentas de CEP, em algumas soluções, tem-se utilizado uma abordagem de modelos Model-Driven Development (MDD), a fim de se produzir uma camada de abstração, que possibilite criar regras, sem que necessariamente seja um usuário especialista em linguagem de CEP. No entanto, muitas dessas soluções acabam tornando-se mais complexas no seu manuseio do que o uso convencional da linguagem de baixo nível. Este trabalho tem por objetivo a construção de uma Graphic User Interface (GUI) para criação de regras de CEP, utilizando MDD, a fim de tornar o desenvolvimento mais intuitivo, através de um modelo adaptado as necessidades do usuário não especialista.
Nowadays is Increasingly evident a greater resources scarcity and competition for physical space, in result of growing up and large population concentration into large cities. In this context, comes up the necessity of solutions that are in compliance with initiative of smart cities. Those solutions seek concentrate monitoring and control, for help to make decisions. Although, this sources of information technology and communications (ITCs) forming complex structures and generates a huge quantity of data that represents biggest challenges and opportunities. One of the main technological tools used in this context is the Complex Event Processing (CEP), which may be considered a good solution to deal with increase of the availability and large volume of data, in real time. The CEPs realizes captation of events in a simple way, using expressive languages, to define and execute processing rules. Although the efficient use of this tools, the fact of the rules being expressed in low level, becomes your use exclusive for specialists, difficulting the creation of solutions. With the aim of reduce the complexity of the CEPs tools, solutions has used an approach of models Model-Driven Development (MDD), in order to produce an abstraction layer, that allows to create rules, without necessarily being a specialist in CEP languages. however, many this tools become more complex than the conventional low level language approach. This work aims to build a Graphic User Interface (GUI) for the creation of CEP rules, using MDD, in order to a more intuitive development, across of the adapted model how necessities of the non specialist users.

Resumen

Primjena Internet protokola u uređajima sa ograničenim resursima, dovodi do radikalne promjene Interneta i pojave potpuno novog koncepta pod nazivom Internet stvâri – Internet of Things (IoT), čiji je jedan od osnovnih gradivnih elemenata Senzor Web (SW) čvor. SW čvor predstavlja elementarni “resurs” u SW mreži koja se po svojoj prirodi može posmatrati kao nestrukturirana kolekcija gradivnih elemenata koji se mogu dinamički orkestrirati u virtuelne klastere, odnosno u arhi-tekturu. Cilj disertacije predstavlja unapređenje procesa razvoja arhitekture sistema baziranih na SW mrežama uz oslonac na dinamičko generisanje servisnog sloja u svrhu povećanja produktivnosti, održivosti i smanjenja troškova razvoja. Pod unapređenjem procesa razvoja arhitekture smatra se analiza, integracija i prilagođavanje postojećih sistema i pristupa projektovanja arhitekture senzorskih mreža, kao i sistema baziranih na IoT konceptima. U tu svrhu definisana je arhitektura SW mreža, kreiran domenski specifičan jezik, interaktivni grafički editor i alat za automatsku transforma-ciju modela u implementacione klase. U sklopu teze izvršena je i eksperimentalna verifikacija predloženog modela i razvojnog okruženja, čime je dokazana njhova praktična primjena.
The use of Internet protocols in limited resources devices contributes to radical changes in the Internet and the emergence of an entirely new concept called the Internet of Things (IoT), consisted of the Sensor Web (SW) nodes as one of the basic building blocks. SW node is the elementary "resource" in the SW Network, which by their nature can be seen as an unstructured collection of blocks that can be dynamically orchestrated into the virtual cluster, or in the architecture. The aim of this thesis is to improve the process of developing a system archite-cture based on SW networks, relying on the dynamic generation of the service layer in order to increase productivity, sustainability and cost of development. The improvement of the architecture development process includes analysis, integration and adaptation of existing systems and sensor network architecture design approaches, as well as systems based on the IoT concepts. For this purpose, the archite-cture of the SW Network is defined, a domain-specific language has been created as well as interactive graphics editor and a tool for automatic transformation of models into the implementation class. As part of the dissertation, the experimental verification of the proposed model and the development environment were carried out demonstra-ting their practical application.

Resumen

Dans cette thèse nous nous sommes intéressés aux problèmes concernant la conception et la gestion des plans de soins à domicile. Un plan de soins à domicile définit l'ensemble des activités médicales et/ou sociales qui sont menées jour après jour au domicile d'un patient. Ce plan de soins est généralement construit à travers un processus complexe impliquant une évaluation complète des besoins du patient ainsi que son environnement social et physique. La spécification de plans de soins à domicile est difficile pour plusieurs raisons: les plans de soins à domicile sont par nature des processus non structurés qui impliquent des activités répétitives mais irrégulières, dont la spécification requiert des expressions temporelles complexes. Ces caractéristiques font que les plans de soins à domicile sont difficiles à modéliser en utilisant les technologies traditionnelles de modélisation de processus. Tout d'abord, nous présentons l'approche basée sur les DSL (Langage spécifique au domaine) qui permet d'exprimer les plans de soins à domicile en utilisant des abstractions de haut niveau et orientées utilisateur. Le DSL nous permet à travers cette thèse de proposer un langage de temporalités permettant de spécifier les temporalités des activités du plan de soins à domicile. Ensuite, nous décrivons comment les plans de soins à domicile, formalisés grâce aux automates temporisés, peuvent être générés à partir de ces abstractions. Nous proposons une approche en trois étapes qui consiste à: (i) le mapping entre les spécifications temporelles élémentaires et les automates temporisés appelés "pattern automata", (ii) la combinaison des "patterns automata" afin de construire les automates d'activités en utilisant l'algorithme de composition que nous avons déni, et aussi (iii) la construction de l'automate de plan de soins à domicile global. L'automate de plan de soins à domicile résultant englobe tous les schedules autorisés des activités pour un patient donné. Enfin, nous montrons comment la vérification et le suivi de l'automate du plan de soins à domicile résultant peuvent être faits en utilisant des techniques et des outils existants, en particulier en utilisant l'outil de verification UPPAAL
In this thesis we are interested in the problems underlying the design and the management of home care plans. A home care plan defines the set of medical and/or social activities that are carried out day after day at a patient's home. Such a care plan is usually constructed through a complex process involving a comprehensive assessment of patient's needs as well as his/her social and physical environment. Specication of home care plans is challenging for several reasons: home care plans are inherently nonstructured processes which involve repetitive, but irregular, activities, whose specification requires complex temporal expressions. These features make home care plans difficult to model using traditional process modeling technologies. First, we present a DSL (Domain Specific Language) based approach tailored to express home care plans using high level and user-oriented abstractions. DSL enables us through this thesis to propose a temporalities language to specify temporalities of home care plan activities. Then, we describe how home care plans, formalized as timed automata, can be generated from these abstractions. We propose a three-step approach which consists in (i) mapping between elementary temporal specifications and timed automata called Pattern automata, (ii) combining patterns automata to build the activity automata using our composition algorithm and then (iii) constructing the global care plan automaton. The resulting care plan automaton encompasses all the possible allowed schedules of activities for a given patient. Finally, we show how verification and monitoring of the resulting care plan can be handled using existing techniques and tools, especially using UPPAAL Model Checker

Resumen

Experimentieren in der vorliegenden Arbeit bedeutet, Experimente auf der Basis von computerbasierten Modellen durchzuführen, wobei diese Modelle Struktur, Verhalten und Umgebung eines Systems abstrahiert beschreiben. Aus verschiedenen Gründen untersucht man stellvertretend für das System ein Modell dieses Systems. Systematisches Experimentieren bei Variation der Modelleingabeparameterbelegung führt in der Regel zu sehr vielen, potentiell lang andauernden Experimenten, die geplant, dokumentiert, automatisiert ausgeführt, überwacht und ausgewertet werden müssen. Häufig besteht dabei das Problem, dass dem Experimentator (der üblicherweise kein Informatiker ist) adäquate Ausdrucksmittel fehlen, um seine Experimentier-Prozesse formal zu beschreiben, so dass sie von einem Computersystem automatisiert ausgeführt werden können. Dabei müssen Verständlichkeit, Nachnutzbarkeit und Reproduzierbarkeit gewahrt werden. Der neue Ansatz besteht darin, generelle Experimentier-Workflow-Konzepte als Spezialisierung von Scientific-Workflows zu identifizieren und diese als eine metamodellbasierte Domain-Specific-Language (DSL) zu formalisieren, die hier als Experimentation-Language (ExpL) bezeichnet wird. ExpL beinhaltet allgemeine Workflow-Konzepte und erlaubt das Modellieren von Experimentier-Workflows auf einer frameworkunabhängigen, konzeptuellen Ebene. Dadurch werden die Nachnutzbarkeit und das Publizieren von Experimentier-Workflows nicht mehr durch die Gebundenheit an ein spezielles Framework behindert. ExpL wird immer in einer konkreten Experimentierdomäne benutzt, die spezifische Anforderungen an Konfigurations- und Auswertemethoden aufweist. Um mit dieser Domänenspezifik umzugehen, wird in dieser Arbeit gezeigt, diese beiden Aspekte separat in zwei weiteren, abhängigen Domain-Specific-Languages (DSLs) zu behandeln: für Konfiguration und Auswertung.
Experimentation in my work means performing experiments based on computer-based models, which describe system structure and behaviour abstractly. Instead of the system itself models of the system will be explored due to several reasons. Systematic experimentation using model input parameter variation assignments leads to lots of possibly long-running experiments that must be planned, documented, automated executed, monitored and evaluated. The problem is, that experimenters (who are usually not computer scientists) miss the proper means of expressions (e. g., to express variations of parameter assignments) to describe experimentation processes formally in a way, that allows their automatic execution by a computer system while preserving reproducibility, re-usability and comprehension. My approach is to identify general experimentation workflow concepts as a specialization of a scientific workflow and formalize them as a meta-model-based domain-specific language (DSL) that I call experimentation language (ExpL). experimentation language (ExpL) includes general workflow concepts like control flow and the composition of activities, and some new declarative language elements. It allows modeling of experimentation workflows on a framework-independent, conceptional level. Hence, re-using and sharing the experimentation workflow with other scientists is not limited to a particular framework anymore. ExpL is always being used in a specific experimentation domain that has certain specifics in configuration and evaluation methods. Addressing this, I propose to separate the concerns and use two other, dependent domain-specific languages (DSLs) additionally for configuration and evaluation.

Resumen

This study aims to design and implement a domain-specific computer programming language: the Building Environment Rule and Analysis (BERA) Language. As a result of the growing area of Building Information Modeling (BIM), there has been a need to develop highly customized domain-specific programming languages for handling issues in building models in the architecture, engineering and construction (AEC) industry. The BERA Language attempts to deal with building information models in an intuitive way in order to define and analyze rules in design stages. The application of the BERA Language aims to provide efficiency in defining, analyzing and checking rules. Specific example applications implemented in this dissertation are on the evaluation of two key aspects: building circulation and spatial programming. The objective of this study is to accomplish an effectiveness and ease of use without precise knowledge of general-purpose languages that are conventionally used in BIM software development. To achieve the goal, this study proposes an abstraction of the universe of discourse - it is the BERA Object Model (BOM). It is a human-centered abstraction of complex state of building models rather than the computation-oriented abstraction. By using BOM, users can enjoy the ease of use and portability of BIM data, rather than complex and platform-dependent data structures. This study also has reviewed and demonstrated its potential for extensibility of BOM. Not only its lateral extensions such as structural building elements, but also the vertical extensions such as additional properties for existing BOM objects are good examples. In current BERA Language Tool, many computed and derived properties/relations have been proposed and implemented, as well as some basic data directly from the given building model. Target users of the BERA Language are domain experts such as architects, designers, reviewers, owners, managers, students, etc., rather than BIM software developers. It means that the people who are interested in the building environment rule and analysis are the potential users. The BERA Language Tool comprises many libraries to alleviate common but unnecessary problems and limitations that are encountered when users attempt to analyze and evaluate building models using commercially available tools. Combined with other libraries which populate rich and domain-specific datasets for certain purposes, the BERA Language will be fairly versatile to define rules and analyze various building environmental conditions.

Resumen

L'engouement du grand public pour les applications mobiles, dont le nombre ne cessede croître, a rendu les utilisateurs de plus en plus exigeants quant à la qualité de cesapplications. Seule une procédure de test efficace permet de répondre à ces exigences.Dans le contexte des applications embarquées sur téléphones mobiles, le test est unetâche coûteuse et répétitive principalement à cause du nombre important de terminauxmobiles qui sont tous différents les uns des autres.Nous proposons dans cette thèse le langage MATeL, un DSML (Domain-Specific ModelingLanguage) qui permet de d’écrire des scénarios de test spécifiques aux applicationsmobiles. Sa syntaxe abstraite, i.e. un méta modèle et des contraintes OCL, permet auconcepteur de manipuler les concepts métier du test d'applications mobiles (testeur, mobileou encore résultats attendus et résultats obtenus). Par ailleurs, il permet d'enrichirces scénarii avec des points de variabilité qui autorisent de spécifier des variations dansle test en fonction des particularités d'un mobile ou d'un ensemble de mobiles. La syntaxeconcrète de MATeL, qui est inspirée de celle des diagrammes de séquence UML,ainsi que son environnement basé sur Eclipse permettent à l'utilisateur de concevoir desscénarii relativement facilement.Grâce à une plateforme de test en ligne construite pour les besoins de notre projet,il est possible d'exécuter les scénarii sur plusieurs téléphones différents. La démarcheest illustrée dans cette thèse à travers des cas d'utilisation et des expérimentations quiont permis de vérifier et valider notre proposition
Mobile applications have increased substantially in volume with the emergence ofsmartphones. Ensuring high quality and successful user experience is crucial to the successof such applications. Only an efficient test procedure allows developers to meet these requirements. In the context of embedded mobile applications, the test is costly and repetitive. This is mainly due to the large number of different mobile devices. In this thesis, we describe MATeL, a Domain-Specific Modeling Language (DSML) for designing test scenarios for mobile applications. Its abstract syntax, i.e. a meta model and OCL constraints, enables the test designer to manipulate mobile applications testing concepts such as tester, mobile or outcomes and results. It also enables him/her to enrich these scenarios with variability points in the spirit of Software Product-Line engineering, that can specify variations in the test according to the characteristics of one mobile or a set of mobiles. The concrete syntax of MATeL that is inspired from UML sequence diagrams and its environment based on Eclipse allow the user to easily develop scenarios. MATeL is built upon an industrial platform (a test bed) in order to be able to run scenarios on several different phones. The approach is illustrated in this thesis through use cases and experiments that led to verify and validate our contribution

Nowadays, tablet and smartphones are commonly used by children for both entertainment and education. Interactive e-book for mobile devices offer a enhanced experience when compared to traditional books, being potentially more engaging and fun for readers. However, to explore the most interesting features in these environments, authors have scarce support. In the sense that there are not many high level support tools and that these features are usually only accessible programmatically. In this work, we intend to extract as main characteristics of interactive e-books and propose a model called Fábulas that allow authors to create declarative interactive e-books. The model was designed based on a systematic analysis of interactive e-books, authoring tools and authoring languages for multimedia applications. In addition, this dissertation presents a case study for an implementation of Fábulas for web browsers with Javascript and HTML and for a SceneSync language.
Hoje em dia, os tablets e smartphones são comumente usados por crianças tanto para entretenimento quanto para educação. E-books interativos em dispositivos móveis permitem uma experiência mais rica quando comparada com livros tradicionais, sendo potencialmente mais envolvente e divertido para os leitores. Contudo, para explorar os recursos mais interessantes nesses ambientes, os autores têm pouco suporte. No sentido de que não existem muitas ferramentas de apoio de nível elevado e que estas funcionalidades são normalmente acessíveis apenas através de programação. Neste trabalho, retendemos extrair as principais características de e-books interativos e propor um modelo chamadoFábulas que permite aos autores criarem e-books interativos declarativamente. O modelo foi concebido tomando como ponto de partida uma análise sistemática de e-books interativos, ferramentas de autoria e linguagens de autoria para aplicações multimídia. Além disso, esta dissertação apresenta um estudo de caso para a implementação de Fábulas para navegadores web com Javascript e HTML e para a linguagem SceneSync.

Resumen

Designing and implementing coupled Earth System Models (ESMs) is a challenge for climate scientists and software engineers alike. Coupled models incorporate two or more independent numerical models into a single application, allowing for the simulation of complex feedback effects. As ESMs increase in sophistication, incorporating higher fidelity models of geophysical processes, developers are faced with the issue of managing increasing software complexity. Recently, reusable coupling software has emerged to aid developers in building coupled models. Effective reuse of coupling infrastructure means increasing the number of coupling functions reused, minimizing code duplication, reducing the development time required to couple models, and enabling flexible composition of coupling infrastructure with existing constituent model implementations. Despite the widespread availability of software packages that provide coupling infrastructure, effective reuse of coupling technologies remains an elusive goal: coupling models is effort-intensive, often requiring weeks or months of developer time to work through implementation details, even when starting from a set of existing software components. Coupling technologies are never used in isolation: they must be integrated with multiple existing constituent models to provide their primary services, such as model-to-model data communication and transformation. Unfortunately, the high level of interdependence between coupling concerns and scientific concerns has resulted in high interdependence between the infrastructure code and the scientific code within a model’s implementation. These dependencies are a source of complexity which tends to reduce reusability of coupling infrastructure. This dissertation presents mechanisms for increasing modeler productivity based on improving reuse of coupling infrastructure and raising the level of abstraction at which modelers work. This dissertation argues that effective reuse of coupling technologies can be achieved by decomposing existing coupling technologies into a salient set of implementation-independent features required for coupling high-performance models, increasing abstraction levels at which model developers work, and facilitating integration of coupling infrastructure with constituent models via component-based modularization of coupling features. The contributions of this research include: (1) a comprehensive feature model that identifies the multi-dimensional design space of coupling technologies used in high-performance Earth System Models, (2) Cupid, a domain-specific language and compiler for specifying coupling configurations declaratively and generating their implementations automatically, and (3) Component-based Coupling Operators (CC-Ops), a modular approach to code reuse of coupling infrastructure based on component technologies for high-performance scientific settings. The Cupid domain-specific language is evaluated by specifying a coupling configuration for an example fluid dynamics model and measuring the amount of code generated by the Cupid compiler compared to a hand coded version. The CC-Op approach is evaluated by implementing several CC-Ops using an existing high-performance component framework and measuring performance in terms of scalability and overhead.

The growth and popularization of wireless connectivity and of mobile devices has allowed the development of smart spaces that were previously only envisaged in the approach proposed by Mark Weiser. These smart spaces are composed of many computational resources, such as devices, services and applications, along with users, who must be able to associate with these features. However, programming these environments is a challenging task, since smart spaces have a dynamic nature, resources are heterogeneous, and it is necessary that interactions between users and devices are coordinated with one another. In this work, we present a new approach for smart spaces programming using Models@RunTime. In this regard, we propose a high level modeling language, called Smart Spaces Modeling Language (2SML), in which the user is able to model the smart space with all elements that can be part of it. Such models are developed by the users, interpreted and effected in the physical space by a model execution engine, called Smart Space Virtual Machine (2SVM), whose development is part of this work.
O crescimento e a popularização cada vez maior da conectividade sem fio e dos dispositivos móveis, tem permitido a construção de espaços inteligentes que antes eram vislumbrados apenas na proposta de computação ubíqua do cientista da Xerox PARK, Mark Weiser. Esses espaços inteligentes são compostos por diversos recursos computacionais, como dispositivos, serviços e aplicações, além de usuários, que devem ser capazes de se associar a esses recursos. Entretanto, a programação destes ambientes é uma tarefa desa- fiadora, uma vez que os espaços inteligentes possuem uma natureza dinâmica, os recursos se apresentam de forma heterogênea e é necessário que as interações entre usuários e dispositivos sejam coordenadas. Neste trabalho desenvolvemos uma nova abordagem para programação de espaços inteligentes, por meio de modelos em tempo de execução. Para isso, propomos uma linguagem de modelagem de alto nível, denominada Smart Space Modeling Language (2SML), em que o usuário é capaz de modelar o espaço inteligente com todos os elementos que dele podem fazer parte. Esse modelo desenvolvido pelo usuá- rio é interpretado e realizado no espaço físico por uma máquina de execução de modelos, denominada Smart Space Virtual Machine (2SVM), cujo desenvolvimento é parte deste trabalho.

Systems which involve adaptations due to context changes have the challenge of adapting software systems at runtime. This thesis adopts as proposal the adaptation of resources in the form of features, involving concepts of Feature Oriented Domain Analysis. A possible approach to develop systems based on adaptable features at runtime is the concept of Dynamic Software Product Line (DSPL), which can be implemented by Metamodels. The aim of this thesis is the development of a Domain Specific Modeling Language (DSML) for DSPL, designed from the construction of a metamodel for the development of DSPLs, which is divided in three metamodels: of features, of variabilities and of applications to derive products. The variabilities metamodel aims at modeling contracts that must negotiate the product adaptation to the features that may be present or not in the execution environment. Adaptations are based in state machines, which address changes of feature state or changes by transitions of equivalent features, in order to keep the execution of the software product. The developed DSML still plays the role of extending the constraints imposed by the metamodels, as well as to generate codes in general-purpose language based on modeling features, variabilities and applications. In order to validate the proposal, the DSML was used to model two DSPLs, including the derivation of products and the execution in a platform based in OSGi specification.
Sistemas que envolvem adaptação em decorrência de mudanças de contexto possuem como desafio a adaptação do sistema de software em tempo de execução. Esta dissertação adota como proposta a adaptação de recursos na forma de características, envolvendo o conceito de Análise de Domínio Orientada a Características. Uma abordagem para o desenvolvimento de sistemas baseados em características adaptáveis em tempo de execução é o conceito de Linha de Produto de Software Dinâmica (LPSD), o qual pode ser implementado por meio do desenvolvimento de Metamodelos. O objetivo desta dissertação é o desenvolvimento de uma Linguagem de Modelagem de Domínio Específico (do inglês, Domain Specific Modeling Language - DSML) para LPSD, concebida a partir da construção de um metamodelo para o desenvolvimento de LPSDs, o qual está dividido em três metamodelos: de características, de variabilidades e de aplicação para derivação de produtos. Em destaque, o metamodelo de variabilidade tem como objetivo a modelagem de contratos que devem negociar a adaptação dos produtos às características que poderão estar ou não presentes no ambiente de execução. As adaptações são baseadas em máquinas de estado, as quais abordam a mudança de estado de uma característica ou a mudança por transição de características equivalentes, com o intuito de manter a execução do produto de software. A DSML desenvolvida tem ainda o papel de estender as restrições impostas pelos metamodelos, assim como gerar códigos em linguagem de propósito geral com base na modelagem de características, variabilidades e aplicações. No sentido de validar a proposta, a DSML foi usada para a modelagem de duas LPSDs, incluindo a derivação de produtos e a execução em uma plataforma baseada na especificação OSGi.

Resumen

Les divers intervenants qui décrivent, étudient et réalisent un système complexe ont besoin de points de vue adaptés à leurs préoccupations. Cependant, dans le contexte de l’Ingénierie Dirigée par les Modèles, les moyens pour définir et mettre en œuvre ces points de vue sont, soit trop rigides et inadaptées, soit totalement ad hoc. De plus, ces différents points de vue sont rarement indépendants les uns des autres. Dès lors, il faut s’attacher à identifier puis décrire les liens/les correspondances qui existent entre les points de vue pour enfin pouvoir vérifier que les réponses apportées par les différents intervenants constituent un tout cohérent.Les travaux exposés dans cette thèse permettent la définition de langages dédiés basés sur UML pour les points de vue. Pour cela, une méthode outillée qui analyse la sémantique des descriptions textuelles des concepts du domaine que l’on souhaite projeter sur UML est proposée afin de faciliter la définition de profils UML. Les résultats obtenus sur les cas d’études concrets étudiés sont encourageants et dépassent les résultats des outils existants. Pour définir des points de vue basés sur des profils UML, cette thèse propose une méthode qui permet au méthodologiste d’expliciter le point de vue voulu. Un outil génère ensuite l’outillage qui met en œuvre ce point de vue dans un environnement de modélisation ainsi que le langage dédié correspondant là où la pratique actuelle repose sur une mise en œuvre essentiellement manuelle.Pour assister l’identification des liens entre points de vue, cette thèse propose là aussi d’analyser la sémantique des descriptions textuelles des concepts des langages utilisés par les points de vue. Utilisée en complément des heuristiques syntaxiques existantes, l’approche proposée permet d’obtenir de bons résultats lorsque les terminologies des langages analysés sont éloignées. Un cadre théorique basé sur la théorie des catégories est proposé pour expliciter formellement les correspondances. Pour utiliser ce cadre, une catégorie pour les langages basés sur UML a été proposée. Afin de pouvoir également expliciter les correspondances entre les modèles issus de ces langages, la catégorie des ontologies OWL est utilisée. Une solution est proposée pour caractériser des correspondances plus complexes que la simple équivalence. Ce cadre théorique permet la définition formelle de relations complexes qui permettront de raisonner sur la cohérence de la description de l’architecture. Une fois la description de l’architecture intégrée en un tout en suivant les correspondances formalisées, la question de la cohérence est abordée. Les expérimentations faites sur un cas d’étude concret pour vérifier la cohérence à un niveau syntaxique donnent des résultats pratiques satisfaisants. Les expérimentations menées sur le même cas pour vérifier la cohérence à un niveau sémantique ne donnent pas de résultats pratiques satisfaisants
The various stakeholders who describe study and implement a complex system require viewpoints that are dedicated to their concerns. However, in the context of Model-Driven Engineering, approaches to define and implement those viewpoints are either too rigid and inappropriate or completely ad hoc. In addition, those various viewpoints are rarely independent from each other. Therefore, we must strive to identify and describe the relationships/correspondences between the viewpoints in order to be able to verify that the parts of the solution given by the various stakeholders form a consistent whole.The work presented in this thesis provides a way to define dedicated languages based on UML for the viewpoints. For this, a method that analyzes the semantics of the textual descriptions of the concepts of the domain we want to map to UML has been implemented to facilitate the definition of UML profiles. The results we get on the concrete test cases we considered are encouraging and go beyond results of existing tools. To define a viewpoint based on some UML profiles, this thesis provides a method that lets the methodologist make explicit the viewpoint he/she wants. A tool can then generate the tooling that implements this viewpoint in a modeling environment together with the corresponding dedicated language while current practice is based on an implementation essentially manual.To assist the identification of relationships between the viewpoints, this thesis proposes again to analyze the semantics of textual descriptions of concepts of the languages used by the viewpoints. Used in combination with existing syntactic heuristics, the proposed approach provides good results when the terminologies of the languages that are analyzed are far apart. A theoretical framework based on category theory is provided to make explicit formally correspondences. To use this framework, a category for languages based on UML has been proposed. To be able to make explicit the correspondences between the models of those languages as well, the category of OWL ontologies is used. A solution is proposed to characterize correspondences that are more complex than the simple equivalence relationship. This theoretical framework provides a way to define formally complex relationships that can be used to verify the consistency of the architectural description. Once the description of the architecture has been integrated according to the formal correspondences, the issue of consistency is considered. The experiments carried out on a concrete test case to verify consistency on a syntactic perspective give satisfactory practical results. The experiments carried on the same test case to verify consistency on a semantic perspective don’t give satisfactory practical results

Resumen

Avec la construction des robots de plus en plus complexes, la croissance des architectures logicielles robotiques et l’explosion de la diversité toujours plus grande des applications et misions des robots, la conception, le développement et l’intégration des entités logicielles des systèmes robotiques, constituent une problématique majeure de la communauté robotique. En effet, les architectures logicielles robotiques et les plateformes de développement logiciel pour la robotique sont nombreuses, et sont dépendantes du type de robot (robot de service, collaboratif, agricole, médical, etc.) et de son mode d'utilisation (en cage, d’extérieur, en milieu occupé, etc.). L’effort de maintenance de ces plateformes et leur coût de développement sont donc considérables.Les roboticiens se posent donc une question fondamentale : comment réduire les coûts de développement des systèmes logiciels robotiques, tout en augmentant leur qualité et en préservant la spécificité et l’indépendance de chaque système robotique? Cette question induit plusieurs autres : d’une part, comment décrire et encapsuler les diverses fonctions que doit assurer le robot, sous la forme d’un ensemble d’entités logicielles en interaction? Et d’autre part, comment conférer à ces entités logicielles, des propriétés de modularité, portabilité, réutilisabilité, interopérabilité, etc.?A notre avis, l’une des solutions les plus probables et prometteuses à cette question consiste à élever le niveau d’abstraction dans la définition des entités logicielles qui composent les systèmes robotiques. Pour ce faire, nous nous tournons vers l’ingénierie dirigée par les modèles, et plus particulièrement la conception des DSML (Domain Specific Modeling Language).Dans cette thèse, nous réalisons dans un premier temps, une étude comparative des langages de modélisation et de méthodes utilisés dans le développement des systèmes embarqués temps réel en général. L’objectif de ce premier travail étant de voir s’il en existe qui puissent permettre de répondre aux questions susmentionnées des roboticiens. Cette étude, non seulement nous montre que ces approches ne sont pas adaptées à la définition des architectures logicielles robotiques, mais elle aboutit surtout à unFramework, que nous proposons et qui aide à choisir la (les) méthode(s) et/ou le(s) langage(s) de modélisation le(s) plus adapté(s) aux besoins du concepteur. Par la suite, nous proposons un DSML baptisé RsaML (Robotic Software Architecture Modeling Language), pour la définition des architectures logicielles robotiques avec prise en compte de propriétés temps réel. Pour ce faire, un méta-modèle est proposé à partir des concepts que les roboticiens ont l’habitude d’utiliser pour la définition de leurs applications. Il constitue la syntaxe abstraite du langage. Les propriétés temps réel sont identifiées à leur tour et incluses dans les concepts concernés. Des règles sémantiques du domaine de la robotique sont ensuite définies sous forme de contraintes OCL, puis intégrées au méta-modèle, pour permettre que des vérifications de propriétés non fonctionnelles et temps réel soient effectuées sur les modèles construits. Le Framework de modélisation EMF d’Eclipse a été utilisé pour mettre en oeuvre un éditeur qui supporte le langage RsaML.La suite des travaux réalisés dans cette thèse a consisté à définir des transformations de modèles, puis à les utiliser pour implémenter des générateurs. Ces derniers permettent à partir d’un modèle RsaML construit, d’une part, de produire sa documentation et, d’autre part, de produire du code source en langage C. Ces contributions sont validées à travers un cas d’étude décrivant un scénario basé sur le robot Khepera III
With the construction of increasingly complex robots, the growth of robotic software architectures and the explosion of ever greater diversity of applications and robots missions, the design, development and integration of software entities of robotic systems, constitute a major problem for the robotics community. Indeed, robotic software architectures and software development platforms for robotics are numerous, and are dependent on the type of robot (service robot, collaborative, agricultural, medical, etc.) and its usage mode (In cage, outdoor, environment with obstacles, etc.).The maintenance effort of these platforms and their development cost are therefore considerable.Roboticists are therefore asking themselves a fundamental question: how to reduce the development costs of robotic software systems, while increasing their quality and preserving the specificity and independence of each robotic system? This question induces several others: on the one hand, how to describe and encapsulate the various functions that the robot must provide, in the form of a set of interactive software entities? And on the other hand, how to give these software entities, properties of modularity, portability, reusability, interoperability etc.?In our opinion, one of the most likely and promising solutions to this question, is to raise the level of abstraction in defining the software entities that make up robotic systems. To do this, we turn to model-driven engineering, specifically the design of Domain Specific Modeling Language (DSML).In this thesis, we first realize a comparative study of modeling languages and methods used in the development of embedded real time systems in general. The objective of this first work is to see if there are some that can make it possible to answer the aforementioned questions of the roboticists. This study not only shows that these approaches are not adapted to the definition of robotic software architectures, but mainly results in a framework, which we propose and which helps to choose the method (s) and / or the modeling language (s) best suited to the needs of the designer. Subsequently, we propose a DSML called Robotic Software Architecture Modeling Language (RsaML), for the definition of robotic software architectures with real-time properties. To do this, a meta-model is proposed from the concepts that roboticists are used to in defining their applications. It constitutes the abstract syntax of the language. Real-time properties are identified and included in the relevant concepts. Semantic rules in the field of robotics are then defined as OCL constraints and then integrated into the meta-model, to allow non-functional and realtime property checks to be performed on the constructed models.Eclipse Modeling Framework has been used to implement an editor that supports the RsaML language. The rest of the work done in this thesis involved defining model transformations and then using them to implement generators. These generators make it possible from a RsaML model built, to produce its documentation and source code in C language. These contributions are validated through a case study describing a scenario based on the Khepera III robot

Resumen

L'intelligence ambiante vise à offrir à un utilisateur humain des applications et des services personnalisés et adaptés à la situation courante. L'environnement ambiant, dans lequel cet humain est plongé, est composé d'un ensemble d'objets connectés et de composants logiciels qui sont des briques de base pour la construction d'applications par composition. La disponibilité de ces composants peut varier dynamiquement, en cas de mobilité par exemple. Ceux-ci peuvent apparaître ou disparaître de manière non anticipée. De plus, dans ces environnements dynamiques et ouverts, le besoin de l'utilisateur humain n'est pas stable ni toujours bien défini. Pour construire des applications dans un tel contexte, et fournir à l'utilisateur "les bonnes applications au bon moment", notre équipe explore une approche originale appelée "composition logicielle opportuniste" : l'idée est de construire des applications à la volée par assemblage de composants logiciels présents dans l'environnement sur le moment, sans se baser sur des besoins explicites ni sur des schémas de construction prédéfinis. C'est l'opportunité qui déclenche la construction des applications à la volée. Elle est contrôlée par un système intelligent, appelé moteur de composition opportuniste, qui doit décider des "bonnes" compositions à effectuer sans contribution explicite de l'utilisateur. Ainsi, les applications "émergent" dynamiquement. Les applications émergentes peuvent être imprévues ou inconnues de l'utilisateur. Au centre du système, ce dernier doit être en informé. Il doit pouvoir les contrôler, c'est-à-dire les accepter ou les rejeter, et s'il a les compétences requises, les modifier ou même construire lui-même des applications en assemblant des composants logiciels présents dans l'environnement ambiant. Dans les tâches de contrôle, l'utilisateur doit être assisté au mieux. D'autre part, pour que le moteur de composition opportuniste construise des assemblages pertinents en l'absence de besoins explicites, il doit recevoir des informations de l'utilisateur. Ceci ne doit cependant pas entraîner, pour l'utilisateur, une surcharge d'information ou d'opérations à effectuer. Dans cette thèse, nous proposons une approche basée sur l'ingénierie dirigée par les modèles (IDM) afin de mettre l'utilisateur "au centre de la boucle". Il s'agit de lui présenter les applications émergentes, de l'assister dans son contrôle et d'extraire des données de feedback utiles à fournir au moteur de composition "intelligent". Notre solution repose sur un métamodèle d'assemblage de composants logiciels, des langages spécifiques à un domaine (DSL) qui supportent la description des applications, un éditeur graphique qui permet d'éditer les applications et de capturer le feedback de l'utilisateur. Différentes transformations de modèle permettent l'interfaçage avec le moteur de composition et la génération de différentes formes de descriptions structurelles et sémantiques des applications pour des utilisateurs différents. En outre, les descriptions peuvent être facilement ajustées à un humain particulier, en changeant ou en adaptant les DSL et les transformations de modèle au profil de l'utilisateur. Dans notre approche, contrairement à l'utilisation classique de l'IDM où les outils et les techniques sont utilisés par les ingénieurs pour développer des logiciels et générer du code, le focus est sur les utilisateurs finaux qui prennent la place des ingénieurs. L'ensemble de la solution a été implémentée et fonctionne de manière couplée avec le moteur de composition opportuniste : notre solution prend en entrée les applications proposées par le moteur, les transforme en des modèles présentables, compréhensibles et modifiables par l'utilisateur, et enfin capture le feedback de l'utilisateur pour le transmettre au moteur pour mettre à jour sa connaissance
Ambient intelligence aims to provide to human users applications and services that are personalized and adapted to the current situation. The ambient environment which surrounds the human consists of a set of connected objects and software components that are bricks used for the construction of applications by composition. The availability of these components can vary dynamically, in case of mobility for example. In addition, their appearance or disappearance is usually unanticipated. Moreover, in these dynamic and open environments, the user needs are not stable nor always well defined. To build these applications and provide the user with "the right applications at the right time", our team explores an original approach called "opportunistic software composition": the idea is to build applications on the fly by assembling software components present in the environment at the time, without relying on explicit user needs or predefined applications models. Here, it is the availability of the components that triggers opportunistically the on-the-fly building of applications. It is controlled by an intelligent system, called opportunistic composition engine, which decides on the "right" compositions to be made without user input. In such a way, the applications "emerge" dynamically from the ambient environment. Thus, emerging applications can be unexpected or unknown to the user. At the center of the system, the latter must be informed of these applications. On the first hand, she/he must be able to control them, i.e., accept or reject them, and if she/he has the required skills, modify them or eventually build applications herself/himself by assembling software components present in the ambient environment. However, in the control tasks, the user must be assisted as well as possible. On the other hand, in order for the opportunistic composition engine to build relevant assemblies in the absence of explicit needs, it must receive information from the user. In this thesis, we propose an approach based on Model Driven Engineering (MDE) in order to put the user "at the center of the loop". The objective is to present the emerging applications to the user, to assist him in his interventions and to extract useful feedback data to provide to the "intelligent" composition engine. Our solution is based on a metamodel for assembling software components, on different domain-specific languages (DSL) that support application descriptions, and on a graphical editor for editing applications and capturing user feedback. Different methods for model transformations are used to generate structural and semantic application descriptions for different users, from the applications models build by the intelligent engine. In addition, the descriptions can be easily adjusted to a particular human, by changing or adapting the DSL and the model transformations to the user's profile. Unlike the traditional use of MDE where tools and techniques are used by engineers to develop software and generate code, the focus in our approach is on the end users. The entire solution has been implemented and works coupled with the engine. That is to say, our solution is able to intercept the applications models built by the engine, to transform them into presentable models that can be understood and modified by the user, and finally to capture the user feedback and give it back to the engine to update its knowledge

Functional programming is concerned with referential transparency, that is, given a certain function and its parameter, that the result will always be the same. However, it seems that this is violated in applications involving uncertainty, such as rolling a dice. This thesis defines the background of probabilistic programming and domain-specific languages, and builds on these ideas to construct a domain-specific embedded language (DSEL) for probabilistic programming in a purely functional language. This DSEL is then applied in a real-world setting to develop an application in use by the Center for Gene Research at Oregon State University. The process and results of this development are discussed.

Resumen

Background: Domain-Specific Languages (DSLs) are programming languages created to a specific domain that a user has pre-conceived. Multi-Agent Systems (MAS) represent a set of systems interacting within an environment, in which many intelligent agents interact with each other. Usability is a property of something that is "capable of being used"and "convenient and practicable for use". Barišic et al. introduced a conceptual framework that supports the iterative development process of DSLs concerning the usability evaluation. Semantic Web Enabled Agent Modeling Language (SEA_ML) is a DSL that supports the modeling and generation of action-based systems for MAS and the Semantic Web. It is defined by 44 visual notations. Objective: Improve SEA_ML’s usability using "The "Physics"of Notations" principles to create a new visual notation for SEA_ML. Method: (1) Participants test the current notation and the new notation on four exercises. For each exercise, a SUS questionnaire is presented. Participants should have better results on the exercises with the new notation. (2) Participants select the notations for SEA_ML. Participants receive a list with figures including the current and the new notation, alongside a set of descriptions for each of the semantic constructs of SEA_ML. Participants should select more icons from the new notation. Results: With the results gathered from each experience it is not clear that the new visual notations are better than the current notations. Limitation: The results from the guidelines were not evaluated broadly. Conclusion: The results for each experiment are not clear that the new notation is better than the current notation. This thesis is part of a scientific and technological co-operation between NOVA LINCS research center at Universidade Nova de Lisboa, Portugal, and Ege University International Computer Institute, Turkey. regarding the project Developing a Framework on Evaluating Domain specific Modeling Languages for Multi-Agent Systems.

Resumen

With the widely use of software technique in everyday applications, the correctness of software becomes more and more important. Formal verification is an important method to improve the correctness of software. However, it mainly takes formal languages as its modeling languages, which are based on mathematical logic, automata or graph theory, hard for learning and domain description. That hinders the applications of formal verification in industry. This dissertation investigates the design and practice of domain modeling and verification language EDOLA, to possess all the features of the usability for domain description, reusability and automatic verification. It proposes a three-level design method with the domain knowledge level, the common module level and the verification support level. The main contributions are summarized as follows: 1. In the domain knowledge level, the extraction and representation methods of the domain knowledge on both job-shop scheduling and PLC control software are proposed. It defines domain-specific operators of the job-shop scheduling problem, timed Petri net, etc. for the job-shop scheduling description. It also defines the operators of the scan cycle pattern, the complete environment pattern and five kinds of verification requests for the PLC domain description. It presents the formal semantics of the defined domain-specific operators, for the further EDOLA definition and its automatic verification. 2. In the common module level, the method to define common operators is presented with real-time as an example for common knowledge. It proposes two kinds of basic time operators and four advanced ones, which help EDOLA to describe real-time features easily and make the reusability of EDOLA design among time-sensitive domains possible. 3. In the verification support level, it presents a properties-oriented abstraction strategy, which reduces the state space and exploring space during automatic verifi- cation. It then formulates the encoding rules from EDOLA to first-order logic, thus implements the verification of the models with infinite states, with the help of first-order logic automatic theorem provers. 4. A prototype of the PLC domain modeling and verification language: EDOLA-PLC are developed and its tools are implemented. The tools provide an EDOLA-PLC editor and a compiler with the functionalities like syntax checking, semantics checking and translation-based automatic verification. 5. A case study of the EDOLA-PLC language on a dock fire-fighting control system is presented. It indicates that EDOLA-PLC is easy to describe both the PLC domain knowledge and the properties to be verified; is easy to describe the common knowledge: real-time and can be verified automatically. The results show that the abstraction strategy adopted in the verification support level of EDOLA-PLC improves the efficiency of automatic verification.

The availability of a visual graphical editor for a target domain is the prerequisite of visual graphical modeling, which has been adopted by classical software development for decades and is especially emphasized in today's model-driven engineering. However, compared with traditional textual editors, developing a visual graphical editor from scratch is not an easy work. As a result, there were frameworks developed such as GEF and GMF aimed to simplify the construction of graphical editors. Even so, however, it is still though hard for an average programmer to construct a visual graphical editor by using these frameworks without a long time of learning.

Indiana University-Purdue University Indianapolis (IUPUI)
This thesis investigates integrating recommender systems into model-driven engineering tools powered by domain-specific modeling languages. The objective of integrating recommender systems into such tools is overcome a shortcoming of proactive modeling where the modeler must inform the model intelligence engine how to progress when it cannot automatically determine the next modeling action to execute (e.g., add, delete, or edit). To evaluate our objective, we integrated a recommender system into the Proactive Modeling Engine, which is a add-on for the Generic Modeling Environment (GME). We then conducted experiments to both subjective and objectively evaluate the enhancements to the Proactive Modeling Engine. The results of our experiments show that integrating recommender system into the Proactive Modeling Engine results in an Average Reciprocal Hit-Rank (ARHR) of 0.871. Likewise, the integration results in System Usability Scale (SUS) rating of 77. Finally, user feedback shows that the integration of the recommender system to the Proactive Modeling Engine increases the usability and learnability of domain-speci c modeling tools.

Resumen

Object-oriented frameworks play an important role in current software engineering practice. Frameworks enable the development of several applications in a particular domain with high levels of reuse. However, although frameworks are a powerful means for software reuse, their reuse interface is typically difficult to learn, a problem which hinders their full potential. Different strategies can be used to overcome this problem, namely by developing documentation, instantiation tools, or a domain-specific language (DSL). Although DSLs provide the most effective support for using a framework, developing and maintaining them are challenging and laborious tasks. This work proposes a technique based on aspect-oriented programming for enhancing framework reuse interfaces, so that framework-based applications can be developed at a higher abstraction level. A pattern language for aiding the design of such reuse interfaces is also presented. Although the adoption of higher level reuse interfaces facilitates framework usage, this work goes one step further and proposes a technique that, capitalizing on such reuse interfaces, enables automation gains on the development of DSLs for instantiating frameworks. By exploiting the close relation between application concepts and code based on the proposed reuse interfaces, ready-to-use DSLs can be automatically extracted using a generic language workbench. A prototype of such language workbench for building domain-specific modeling languages has been implemented, and the proposed techniques have been evaluated using two real frameworks.

Resumen

Relatório de estágio de mestrado em Matemática e Computação
Genericamente, ChatBots são programas que interagem com utilizadores humanos através de linguagens naturais. Os ChatBots podem ser criados com objetivos muito diversos, como por exemplo manter uma conversa “inteligente” com um humano, ou prestar serviços em algum domínio concreto, como seja atender chamadas num call-center, reencaminhado-as para um operador. Dada a heterogeneidade dos ChatBots, é importante identificar os seus princípios gerais de organização e de funcionamento. Neste trabalho foi desenvolvida uma proposta original de modelação de ChatBots, que procura identificar estes princípios gerais. Na modelação que desenvolvemos, os ChatBots são organizados em três componentes principais: a interface com o utilizador, o núcleo e o estado do ChatBot. O núcleo é a peça central do funcionamento do Chatbot, pois ele é responsável por processar as interações recebidas do utilizador, gerando reações em resposta. O núcleo contém um conjunto de regras que associam funções de reação a padrões linguísticos que, juntamente com o estado do ChatBot, determinam a escolha da reação a uma dada interação do utilizador. Para a modelação de padrões linguísticos, desenvolvemos aquilo que designamos por expressões regulares linguísticas (ERL). As ERL baseiam-se em expressões regulares, envolvendo etiquetas gramaticais, e incluem um mecanismo para extração das palavras-chave de um padrão linguístico, e deram origem a uma Domain Specific Language. A modelação que desenvolvemos permite a criação de um motor geral para a construção de ChatBots. Para uma prova de conceito, foi criado o Diabrete: um motor geral, open-source, escrito em Python, versão 3, com a base de dados em MySQL, que permite a criação de ChatBots que seguem a modelação desenvolvida neste trabalho. Na implementação do Diabrete recorremos a algumas ferramentas opensource, para levar a cabo as tarefas da análise sintática das frases dos utilizadores (biblioteca FreeLing) e para a construção de um classificador baseado em técnicas de machine learning para a escolha da reação a apresentar a uma dada interação do utilizador (biblioteca NLTK).
ChatBots are programs that interact with human users through natural languages. ChatBots can be created for very different purposes, such as maintaining an ”inteligent”conversation with a human, or providing services in a specific domain, such as answering calls in a call-center, and forward them to an operator. Given the heterogeneity of ChatBots, it becomes important to identify their general principles of organization and operation. In this work, we identify some of these general principles, and develop a new proposal for the modeling of ChatBots. In the developed model, ChatBots are organized into three main components: the user interface, the core of the ChatBot, and the state of the ChatBot. The core is the centerpiece of Chatbot’s operation, as it is responsible for processing the interactions received from the user, generating reactions in response. The core contains a set of rules that associates reaction functions with linguistic patterns that, together with the state of the ChatBot, determine the choice of reaction to a given user interaction. For modeling linguistic patterns, we develop what we call regular linguistic expressions (ERL). ERLs are based on regular expressions involving grammatical tags, include a mechanism for extracting the keywords from a linguistic standard, and have given rise to a Domain Specific Language. The model that we developed allows the design of a general generator for the construction of ChatBots. For a proof of concept, the Diabrete was created. Diabrete is a general, open-source generator, written in Python, version 3, with the database in MySQL, which allows the construction of ChatBots that follow the modeling developed in this work. In the implementation of Diabrete, we used some opensource tools to perform the tasks of the user-generated sentences (library FreeLing) and to construct a classifier based on machine learning techniques for the choice of reaction to be presented to a given user interaction (library NLTK).

Resumen

In the context of world economies transitioning to services, telecommunications services are the primary means of communication between different economic entities and are therefore essential. The focus on the end consumer, the convergence with the Internet, the separation between the software and the hardware implementing a service, and the telecommunications market deregulation have led to a revolution and a new era in the telecommunications industry. To meet these challenges, former national telecommunications providers have to reduce the construction time, from months to days, while affecting non-negatively other parameters (e.g., cost, quality of service, quality of experience) of new telecommunications services. To tackle this broad theme, we propose a telecommunications service construction process, the software tools that are to be used in this process and a tool building process to build them. The telecommunications service construction process reflects current practices in the telecommunications industry. As such, it should be (easily) accepted by practitioners. The software tools (i.e., Domain Specific Modeling Languages designed as profiles of an Enterprise Architecture Modeling Language, graphical editors, code generators, Off the Shelf network simulators, a collaboration Design Rationale Domain Specific Modeling Language) help telecommunications providers face the challenges. The tool building process relies on models and provides a high automation degree, hence software tools can be build more rapidly. We illustrate the telecommunications service construction process and the tools using a multimedia conferencing service. Our proposals contribute to reducing the construction time of new telecommunications services, while providing the possibility of improved quality of service and increased involvement of the consumer. Faster provisioning of new telecommunications services, that better answer the consumers¿ needs, will increase the rate of development of new economic services in general, and will ultimately have a positive impact on world economic development.
