Abstract:
This article describes TagML, a method to generate collections of XML documents using model-to-model (M2M) transformations. To accomplish this goal, we define the TagML meta-model and the TagML-to-XML model-to-text transformation. While TagML models represent the essential characteristics of collections of XML documents, the TagML-to-XML transformation generates the textual representation of collections of XML documents from TagML models. This approach enables developers to define model-to-model transformations to generate TagML models. These models are turned into text applying the TagML-to-XML transformation. Consequently, developers are able to use declarative languages to define model-to-text transformations that generate XML documents, instead of traditional archetype-based languages to define model-to-text transformations that generate collections of XML documents. The TagML model editor as well as the TagML-to-XML transformation were developed as Eclipse plugins using the Eclipse Modeling Framework. The plugin has been developed following the Object Modeling Group standards to ensure the compatibility with legacy tools. Using TagML, unlike other previous proposals, implies the use of model-to-model transformations to generate XML documents, instead of model-to-text transformations, which results on an improvement of the transformation readability and reliability, as well as a reduction of the transformation maintenance costs. The proposed approach helps developers to define transformations less prone to errors than using the traditional approach. The novelty of this approach is based on the way XML documents are generated using model-to-model transformations instead of traditional model-to-text transformations. Moreover, the simplicity of the proposed approach enables the generation of XML documents without the need for any transformation configuration, which does not penalize the model reuse. To illustrate the features of the proposal, we present the generation of XHTML documents using UML class diagrams as input models. The evaluation section demonstrates that the proposed method is less prone to errors than the traditional one.

Abstract:
Over the past decade, the concept of data warehousing has been widely accepted. The main reason for building data warehouses is to improve the quality of information in order to achieve specific business objectives such as competitive advantage or improved decision-making. However, there is no formal method for deriving a multidimensional schema from heterogeneous databases that is recognized as a standard by the OMG and the professionals of the field. Which is why, in this paper, we present a model-driven approach (MDA) for the design of data warehouses. To apply the MDA approach to the Data warehouse construction process, we describe a multidimensional meta-model and specify a set of transformations from a UML meta-model which is mapped to a multidimensional meta-model. The transformation rules are programmed by the Query View Transformation (QVT) language. A case study illustrates our approach. It demonstrates how it reinforces the components traceability and reusability and how it globally improves the modeler’s efficiency. Furthermore, the use of the UML, as a technique to build data warehouses, is an important facilitator which prepares our further work to automate this approach.

Abstract:
Purpose The purpose of this work is to apply a recently proposed constitutive model for mechanically induced martensitic transformations to the prediction of transformation loci. Additionally, this study aims to elucidate if a stress-assisted criterion can account for transformations in the so-called strain-induced regime. Design/methodology/approach The model is derived by generalising the stress-based criterion of Patel and Cohen (1953), relying on lattice information obtained using the Phenomenological Theory of Martensite Crystallography. Transformation multipliers (cf. plastic multipliers) are introduced, from which the martensite volume fraction evolution ensues. The associated transformation functions provide a variant selection mechanism. Austenite plasticity follows a classical single crystal formulation, to account for transformations in the strain-induced regime. The resulting model is incorporated into a fully implicit RVE-based computational homogenisation finite element code. Findings Results show good agreement with experimental data for a meta-stable austenitic stainless steel. In particular, the transformation locus is well reproduced, even in a material with considerable slip plasticity at the martensite onset, corroborating the hypothesis that an energy-based criterion can account for transformations in both stress-assisted and strain-induced regimes. Originality/value A recently developed constitutive model for mechanically induced martensitic transformations is further assessed and validated. Its formulation is fundamentally based on a physical metallurgical mechanism and derived in a thermodynamically consistent way, inheriting a consistent mechanical dissipation. This model draws on a reduced number of phenomenological elements and is a step towards the fully predictive modelling of materials that exhibit such phenomena.

Abstract:
If individual participant data are available from multiple studies or clusters, then a prediction model can be externally validated multiple times. This allows the model’s discrimination and calibration performance to be examined across different settings. Random-effects meta-analysis can then be used to quantify overall (average) performance and heterogeneity in performance. This typically assumes a normal distribution of ‘true’ performance across studies. We conducted a simulation study to examine this normality assumption for various performance measures relating to a logistic regression prediction model. We simulated data across multiple studies with varying degrees of variability in baseline risk or predictor effects and then evaluated the shape of the between-study distribution in the C-statistic, calibration slope, calibration-in-the-large, and E/O statistic, and possible transformations thereof. We found that a normal between-study distribution was usually reasonable for the calibration slope and calibration-in-the-large; however, the distributions of the C-statistic and E/O were often skewed across studies, particularly in settings with large variability in the predictor effects. Normality was vastly improved when using the logit transformation for the C-statistic and the log transformation for E/O, and therefore we recommend these scales to be used for meta-analysis. An illustrated example is given using a random-effects meta-analysis of the performance of QRISK2 across 25 general practices.

Abstract:
<span>The growth of application architectures in all areas (e.g. Astrology, Meteorology, E-commerce, social network, etc.) has resulted in an exponential increase in data volumes, now measured in Petabytes. Managing these volumes of data has become a problem that relational databases are no longer able to handle because of the acidity properties. In response to this scaling up, new concepts have emerged such as NoSQL. In this paper, we show how to design and apply transformation rules to migrate from an SQL relational database to a Big Data solution within NoSQL. For this, we use the Model Driven Architecture (MDA) and the transformation languages like as MOF 2.0 QVT (Meta-Object Facility 2.0 Query-View-Transformation) and Acceleo which define the meta-models for the development of transformation model. The transformation rules defined in this work can generate, from the class diagram, a CQL code for creation column-oriented NoSQL database.</span>

Abstract:
Conceptual models are built to depict and analyze complex systems. They are made of concepts and relationships among these concepts. In a particular domain, conceptual models are helpful for different stakeholders to reach a clear and unified view of domain problems. However, the process of building conceptual models is time-consuming, tedious, and expertise required. To improve the efficiency of the building process, this paper proposes a configurable semantic-based (semi-) automatic conceptual model transformation methodology (SbACMT) that tries to reuse existing conceptual models to generate new models. SbACMT contains three parts: (i) a configurable semantic relatedness computing method building on the structured linguistic knowledge base “ConceptNet” (SRCM-CNet), (ii) a specific meta-model, which follows the Ecore standard, defines the rules of applying SRCM-CNet to different conceptual models to automatically detect transformation mappings, and (iii) a multistep matching and transformation process that employs SRCM-CNet. A case study is carried out to detail the working mechanism of SbACMT. Furthermore, through a systematically analysis of this case study, we validate the performance of SbACMT. We prove that SbACMT can support the automatic transformation process of conceptual models (e.g., class diagrams). The scalability of SbACMT can be improved by adapting the meta-model and predefined syntax transformation rules.

Abstract:
In today’s world we see that Embedded Systems forms a major part in the life of a human being. Almost every device today has an electronic chip embedded in it. When it comes to automotive, these electronic devices are multiplying. This has resulted in innovative methods of developing Embedded Systems. Among them, Model Based Development has become very popular and a standard way of developing embedded systems. Now, we can see that most embedded systems, especially the automotive systems, are being developed using Model development tools like Simulink. In the design and development of Driver Assistance System, Model Based Design (MBD) plays an important role from system design and simulation to code generation. Modeling tool Matlab/Simulink is now among the most popular tools. Due to the proprietary nature of Simulink and challenges in requirement elicitation phase the industry is looking towards an open source alternative, such as Scicos. Since, most of the OEMs are still using Simulink, there is a need for interoperability between Simulink and Scicos. The present work proposes metamodels for Simulink and Scicos, and Model transformation using these Metamodels for the inter-operability. In order to develop the model transformation the metamodels for Simulink and Scicos were developed using EMF Ecore. These metamodels conform to OMGs MOF Standards. These metamodels were used in developing the transformation definition using the language QVTo. First a simple model was developed, and transformation rules were applied and verified using it. Then a Simulink subsystem of a cross wind assistance system was subjected to forward transformation. The outputs of the model before transformation and that after transformation were compared. They were found to give the same output as desired. Thus, verifying the transformation definition. An attempt was made to achieve reverse transformation. A subsystem in Scicos was considered for reverse transformation. After subjecting it to transformation, an intermediate model conforming to Simulink metamodel was obtained. This shows that the interoperability between Scicos and Simulink can be achieved.

Abstract:
Enterprise models are usually developed with ambition to capture the current or desired situation in enterprises with respect to performed or planned processes, organizational structure (including organization units, roles and competences), products or services produced and IT systems available in the enterprise.The above aspects are mutually reflective. Such enterprise models are often represented in formal modeling languages, like UEML (Unified Enterprise Modeling Language) or GEM (General Entity Manipulator) language allowing for the development of applications, which interprets or compute them. Enterprise ontologies basically allow the representation of the same aspects of an enterprise (processes, organizational structure, products and systems). However, enterprise ontologies use another representation (like OWL- Web Ontology Language) and often are developed for other application purposes than enterprise model. The objective of this thesis is to develop strategies for transforming enterprise models into enterprise ontologies.  There should be maximum preservation of semantics and minimum loss of information during the process of transformation. On the basis of meta-model (model to model) transformation, we propose three elements mapping approaches. Each approach has a number of elements mapping rules. After comparative study the best suitable approach according to objective of this thesis is selected for implementation purpose. From a technical perspective, a tool named “EM2EO” is developed, which accepts an enterprise model as input and produces ontology as output.

This thesis proposes an engineering approach to parallelize existing DEVS simulators without having to modify the algorithms of the initial implementation, but by injecting additional components suitable for inter-component communication protocol into force. The simulation algorithms of these new components called "Coats" are defined.An engineering approach to systematize the passage from one implementation to its counterpart parallel and distributed is then proposed. This approach is based on metamodeling and models transformation principles inspired of Model Driven Engineering (MDE). Its genericity guarantees the reusability with any sequential DEVS simulator

Abstract:
Over the past decade the capabilities of autonomous systems have been steadily increasing. Unmanned systems are moving from systems that are predominantly remotely operated, to systems that include a basic decision making capability. This is a trend that is expected to continue with autonomous systems making decisions in increasingly complex environments, based on more abstract, higher-level missions and goals. These changes have significant implications for how these systems should be designed and engineered. Indeed, as the goals and tasks these systems are to achieve become more abstract, and the environments they operate in become more complex, are current approaches to verification and validation sufficient? Domain Specific Modelling is a key technology for the verification of autonomous systems. Verifying these systems will ultimately involve understanding a significant number of domains. This includes goals/tasks, environments, systems functions and their associated performance. Relational Model Transformations provide a means to utilise, combine and check models for consistency across these domains. In this thesis an approach that utilises relational model transformation technologies for systems verification, Systems MDD, is presented along with the results of a series of trials conducted with an existing relational model transformation language (QVT-Relations). These trials identified a number of problems with existing model transformation languages, including poorly or loosely defined semantics, differing interpretations of specifications across different tools and the lack of a guarantee that a model transformation would generate a model that was compliant with its associated meta-model. To address these problems, two related solvers were developed to assist with realising the Systems MDD approach. The first solver, MMCS, is concerned with partial model completion, where a partial model is defined as a model that does not fully conform with its associated meta-model. It identifies appropriate modifications to be made to a partial model in order to bring it into full compliance. The second solver, TMPT, is a relational model transformation engine that prioritises target models. It considers multiple interpretations of a relational transformation specification, chooses an interpretation that results in a compliant target model (if one exists) and, optionally, maximises some other attribute associated with the model. A series of experiments were conducted that applied this to common transformation problems in the published literature.

Para esta análise, investigamos ainda as teorias clássicas da Argumentação, em especial os conceitos de convicção e persuasão, constatando que a “modelagem” oferece ao Sujeito recursos para ampliar seu repertório lingüístico, apreender novos significados a partir de seus próprios enunciados e, por meio da deliberação consigo mesmo, convencer-se e persuadir-se.
This study aims at presenting the origins of the Neuro-Linguistic Programming (NLP), its main ideas, theoretical presuppositions and goals. Furthermore, it will be analyzed the meta-model, its relationship with language and its exploitation through the modeling process, all based on the book The structure of magic I: a book about language and therapy, by Richard Bandler and John Grinder, the founders of NLP. Moreover, it will be examined the transformations obtained from the derivation process, based on Noam Chomsky´s Transformational-generative grammar, with the goal of verifying its relationship with the meta-model. When exploiting the subject´s discourse submitted for the process of modeling, it will be verified in which way the new semantic contents revealed by the transformations could influence that subject and made him alter his vision of the world. For this analysis, it will be investigated also the classic theories of Argumentation, especially the conviction and persuasion concepts. It will also be verified that the process of modeling can offer resources to the subject, for him to enhance his linguistic vocabulary, to learn new meanings from his own sentences and to be able to persuade and convince himself through deliberating with his inner self.

Abstract:
L'évolution rapide des besoins dus entre autres à l'innovation technique, la concurrence ou la réglementation conduit souvent à décrire le cadre d'étude des systèmes d'information dans des modèles conceptuels, pour faciliter l'évolution du fonctionnement des systèmes. La mise au point de ces modèles s'effectue en plusieurs phase au cours desquelles collaborent plusieurs équipes de nature différente, chaque intervenant apportant sa perception du système à construire en se limitant à la partie de son domaine de spécialisation. Il faut alors concilier les différentes perceptions. L'objectif essentiel de la thèse est de concevoir les mécanismes permettant d'une part d'obtenir le modèle factorisant les concepts communs à plusieurs modèles et, d'autre part, de proposer aux concepteurs une méthodologie de suivi de l'évolution de la factorisation. Pour réaliser la factorisation, nous avons mis en œuvre l'Analyse Formelle de Concepts et l'Analyse Relationnelle de Concepts (ARC) qui sont des méthodes d'analyse de données basées sur la théorie des treillis. Dans un ensemble d'entités décrites par des caractéristiques, les deux méthodes extraient des concepts formels qui associent un ensemble maximal d'entités à un ensemble maximal de caractéristiques partagées. Ces concepts formels sont structurés dans un ordre partiel de spécialisation qui les munit d'une structure de treillis. L'ARC permet de compléter la description des entités par des relations entre entités. La première contribution de la thèse est une méthode d'analyse de l'évolution de la factorisation d'un modèle basée sur l'AFC et l'ARC. Cette méthode s'appuie la capacité de l'AFC et de l'ARC à faire émerger au sein d'un modèle des abstractions thématiques de niveau supérieur, améliorant ainsi la sémantique des modèles. Nous montrons que ces méthodes peuvent aussi être employées pour suivre l'évolution du processus d'analyse avec des acteurs. Nous introduisons des métriques sur les éléments de modélisation et sur les treillis de concepts qui servent de base à l'élaboration de recommandations. Nous effectuons une expérimentation dans laquelle nous étudions l'évolution des 15 versions du modèle de classes du système d'information SIE-Pesticides. La seconde contribution de la thèse est une étude approfondie du comportement de l'ARC sur des modèles UML. Nous montrons l'influence de la structure des modèles sur différentes variables étudiées (comme les temps d'exécution et la mémoire occupée) au travers de plusieurs expérimentations sur les 15 versions du modèle SIE-Pesticides. Pour cela, nous étudions plusieurs configurations (choix d'éléments et de relations dans le méta-modèle) et plusieurs paramètres (choix d'utiliser les éléments non nommés, choix d'utiliser la navigabilité). Des métriques sont introduites pour guider le concepteur dans le pilotage du processus de factorisation et des recommandations sur les configurations et paramétrages à privilégier sont faites. La dernière contribution est une approche de factorisation inter-modèles afin de regrouper au sein d'un modèle l'ensemble des concepts communs à différents modèles sources conçus par différents experts. Outre le regroupement des concepts communs, cette analyse produit de nouvelles abstractions généralisant des concepts thématiques existants. Nous appliquons notre approche sur les 15 versions du modèle du SIE-Pesticides. L'ensemble de ces travaux s'inscrit dans un cadre de recherche dont l'objectif est de factoriser des concepts thématiques au sein d'un même modèle et de contrôler par des métriques la profusion de concepts produits par l'AFC et surtout par l'ARC
The rapidly changing needs among other things due to technical innovation, competition and regulation often leads to describe the context for the study of conceptual models in information systems to facilitate the evolution of operating systems. The development of these models is carried out in several phases during which several working teams of different nature, providing each participant's perception of the system to be built is limited to the part of his area of specialization. It must then reconcile the different perceptions.The main objective of the thesis is to design mechanisms to obtain a share of the model factoring concepts common to several models and, secondly, to provide designers with a methodology for monitoring the evolution of factorization.To perform the factorization, we have implemented the Formal Concept Analysis and Relational Concepts Analysis (RCA), which are methods of analysis based on the theory of lattice data. In a set of entities described by features, both methods extract formal concepts that combine a maximum of entities to a maximum set of shared characteristics together. These formal concepts are structured in a partial order of specialization that provides with a lattice structure.The CRA can complement the description of the entities by relationships between entities.The first contribution of the thesis is a textbf {method a model for analyzing the evolution of the factorization based on the FCA and the RCA}. This method builds the capacity of the AFC and the CRA to emerge in a model of thematic abstractions higher level, improving semantic models. We show that these methods can also be used to monitor the analytical process with stakeholders. We introduce metrics on the design elements and the concept lattices which are the basis for the development of recommendations. We conduct an experiment in which we study the evolution of the 15 versions of the model class of information-Pesticides EIS system.The second contribution of this thesis is a textbf {depth study of the behavior of the RCA on UML models.} We show the influence of model structure on different variables studied (such as execution time and memory used) through several experiments on 15 versions of the EIS-Pesticides model. For this, we study several configurations (choice of elements and relations in the meta-model) and several parameters (choice of using unnamed elements, choice of using airworthiness). Metrics are introduced to guide the designer in managing the process of factoring and recommendations on the preferred configurations and settings are made.The last contribution is a textbf {approach to inter-model factorization} to group in a model all the concepts common to different source models designed by different experts. In addition to the consolidation of common concepts, this analysis produces new abstractions generalizing existing thematic concepts. We apply our approach on 15 versions of the model EIS-Pesticides.All this work is part of a research framework which aims to factor thematic concepts within a model and control metrics by the profusion of concepts produced by the FCA and especially by RCA

Abstract:
Ce travail de thèse porte sur la problématique d'élaboration de modèles de systèmes hétérogènes. Il a associé le laboratoire de recherche LAAS-CNRS et la société MENTOR GRAPHICS. Il prend place au sein d'un processus de conception qui se fonde sur les recommandations de l'EIA-632 et sur une ingénierie guidée par les modèles. L'objectif de notre travail est de montrer en quoi le langage VHDL-AMS est adapté à la problématique de modélisation et de simulation de la solution physique au sens des recommandations de l'EIA-632. Dans un premier temps, ce manuscrit présente un état de l'art sur les besoins en modélisation pour la conception système, et dresse un bilan sur les différents langages de modélisation susceptibles d'y répondre. Afin de proposer la norme VHDL-AMS (IEEE 1076.1-1999) comme solution, notre travail s'est attaché à présenter et proposer une méthode à mettre en oeuvre pour converger vers cette norme. Notre démarche s'appuie sur l'ingénierie guidée par les modèles avec une place prépondérante jouée par les transformations de modèle. Nous avons développé ce concept de transformation en vue d'une convergence vers le VHDL-AMS : nous développons la notion de meta modèle avec, entre autre, la création d'un meta modèle du langage VHDL-AMS. Celui-ci va permettre une vérification de la conformité des modèles créés, mais aussi l'écriture de règles de transformations au niveau meta modèle. L'intérêt des industriels possédant un existant de modèles écrits dans un langage de description de matériel propriétaire autre (par exemple le langage MAST) en vue d'une migration vers la norme VHDL-AMS, nous a permis d'éprouver cette méthodologie dans de nombreux cas concrets. Nous avons aussi comparé cette approche à une méthodologie que nous avions précédemment définie, nécessitant une expertise dans les deux langages source et cible. Cela nous a permis de conclure positivement sur la faisabilité d'une telle transformation avec une semi-automatisation et une expertise encore n écessaire à certaines étapes. A titre de démonstration, nous avons développé de nombreux modèles mixtes confirmant les aptitudes du VHDL-AMS à pouvoir être le support principal du prototypage virtuel, ainsi que la validité de notre méthode de transformation. Nous avons notamment réalisé la modélisation VHDL-AMS d'un système très hétérogène de mise à feu d'une charge pyrotechnique, qui valide notre méthodologie. La validation des modèles en conformité avec les spécifications est une des perspectives identifiées de nos travaux, à approfondir.

Abstract:
Police leadership has traditionally been dominated by the commander style, yet the more recent generation of police officers reject this style of leadership. Little, however, is known about whether the different leadership styles of the full range of leadership model result in positive outcomes in policing organizations. The purpose of this quantitative meta-analysis study was to examine the relationship between transformational, transactional, and laissez-faire leadership styles and the leadership outcomes in a policing context, such as subordinate satisfaction, perception of leadership effectiveness, and exerting extra effort. Data for this research synthesis derived from primary research studies, which included 9 U.S. and international correlational policing studies that together comprised 1,939 police officers who completed the Multifactor Leadership Questionnaire (MLQ) instrument. The meta-analysis provided effect size estimates on the relationship between transformational, transactional, and laissez-faire leadership styles and perception of leadership effectiveness, extra effort, and subordinate satisfaction. The results of this meta-analysis indicate the transformational style has a stronger positive relationship with perception of leadership effectiveness, extra effort, and subordinate satisfaction, than the other 2 leadership styles. The positive social change implications of this study provide recommendations to police executives to include transformational leadership with contemporary law enforcement practices. The transformational style may result in improvements to police officer motivation, performance, and job satisfaction, thus offering opportunities to improve public safety outcomes.
