Scrobonia, David. "Rules Based Analysis Engine for Application Layer IDS." DigitalCommons@CalPoly, 2017. https://digitalcommons.calpoly.edu/theses/1773.
Full textAbstract:
Web application attack volume, complexity, and costs have risen as people, companies, and entire industries move online. Solutions implemented to defend web applications against malicious activity have traditionally been implemented at the network or host layer. While this is helpful for detecting some attacks, it does not provide the gran- ularity to see malicious behavior occurring at the application layer. The AppSensor project, an application level intrusion detection system (IDS), is an example of a tool that operates in this layer. AppSensor monitors users within the application by observing activity in suspicious areas not able to be seen by traditional network layer tools. This thesis aims to improve the state of web application security by supporting the development of the AppSensor project. Specifically, this thesis entails contributing a rules-based analysis engine to provide a new method for determining whether suspicious activity constitutes an attack. The rules-based method aggregates information from multiple sources into a logical rule to identify malicious activity, as opposed to relying on a single source of information. The rules-based analysis engine is designed to offer more flexible configuration for administrators and more accurate results than the incumbent analysis engine. Tests indicate that the new engine should not hamper the performance of AppSensor and use cases highlight how rules can be leveraged for more accurate results.

Full textAbstract:
This thesis describes a proposed design and implementation of a predictive maintenance engine developed to fulfill the requirements of the STO Company (Societe de transport de l'Outaouais) for maintaining vehicles in the fleet. Predictive maintenance is proven to be an effective approach and has become an industry standard in many fields. However, in the transportation industry, it is still in the stages of development due to the complexity of moving systems and the high level dimensions of involved parameters. Because it is almost impossible to cover all use cases of the vehicle operational process using one particular approach to predictive maintenance, in our work we take a systematic approach to designing a predictive maintenance system in several steps. Each step is implemented at the corresponding development stage based on the available data accumulated during system funсtioning cycle.
% by dividing the entire system into modules and implementing different approaches.
This thesis delves into the process of designing the general infrastructural model of the fleet management system (FMS), while focusing on the edge gateway module located on the vehicle and its function of detecting maintenance events based on current vehicle status. Several approaches may be used to detect maintenance events, such as a machine learning approach or an expert system-based approach. While the final version of fleet management system will use a hybrid approach, in this thesis paper we chose to focus on the second option based on expert knowledge, while machine learning has been left for future implementation since it requires extensive training data to be gathered prior to conducting experiments and actualizing operations.
Inspired by the IDEA methodology which promotes mapping business rules as software classes and using the object-relational model for mapping objects to database entities, we take active database features as a base for developing a rule engine implementation. However, in contrast to the IDEA methodology which seeks to describe the specific system and its sub-modules, then build active rules based on the interaction between sub-systems, we are not aware of the functional structure of the vehicle due to its complexity. Instead, we develop a framework for creating specific active rules based on abstract classifications structured as ECA rules (event-condition-action), but with some expansions made due to the specifics of vehicle maintenance. The thesis describes an attempt to implement such a framework, and particularly the rule engine module, using active database features making it possible to encapsulate the active behaviour inside the database and decouple event detection from other functionalities. We provide the system with a set of example rules and then conduct a series of experiments analyzing the system for performance and correctness of events detection.

Diante do ambiente complexo e dinâmico encontrado nas empresas atualmente, o sistema tradicional de Workflow não está sendo flexível suficiente para modelar Processos de Negócio. Nesse contexto, surgiram os Processos Flexíveis que tem por principal objetivo suprir a necessidade de modelar processos menos estáticos. Processo declarativo é um tipo de processo flexível que permite os participantes decidirem a ordem em que as atividades são executadas através de regras de negócio. As regras de negócio determinam as restrições e obrigações que devem ser satisfeitas durante a execução. Tais regras descrevem o que deve ou não deve ser feito durante a execução do processo, mas não definem como. Os métodos e ferramentas atualmente disponíveis para modelar e executar processos declarativos apresentam várias limitações que prejudicam a sua utilização para este fim. Em particular, a abordagem que emprega lógica temporal linear (LTL) sofre do problema de explosão de estados a medida que o tamanho do modelo do processo cresce. Embora mecanismos eficientes em relação a memória terem surgido, eles não são capazes de adequadamente garantir a conclusão correta do processo, uma vez que permitem o usuário alcançar estados proibidos ou que causem deadlock. Além disso, as implementações atuais de ferramentas para execução de processos declarativos se concentram apenas em atividades manuais. Comunicação automática com aplicações externas para troca de dados e reutilização de funcionalidade não é suportado. Essas oportunidades de automação poderiam ser melhor exploradas por uma engine declarativa que se integra com tecnologias SOC existentes. Este trabalho propõe uma nova engine de regras baseada em grafo, chamado de REFlex. Tal engine não compartilha os problemas apresentados pelas abordagens disponíveis, sendo mais adequada para modelar processos de negócio declarativos. Além disso, REFlex preenche a lacuna entre os processos declarativos e SOC. O orquestrador REFlex é um orquestrador de serviços declarativo, eficiente e dependente de dados. Ele permite que os participantes chamem serviços externos para executar tarefas automatizadas. Diferente dos trabalhos relacionados, o algoritmo de REFlex não depende da geração de todos os estados alcançáveis, o que o torna adequado para modelar processos de negócios grandes e complexos. Além disso, REFlex suporta regras de negócio dependentes de dados, o que proporciona sensibilidade ao contexto.
Declarative business process modeling is a flexible approach to business process management in which participants can decide the order in which activities are performed. Business rules are employed to determine restrictions and obligations that must be satisfied during execution time. Such business rules describe what must or must not be done during the process execution, but do not prescribe how. In this way, complex control-flows are simplified and participants have more flexibility to handle unpredicted situations. The methods and tools currently available to model and execute declarative processes present several limitations that impair their use to this application. In particular, the well-known approach that employs Linear Temporal Logic (LTL) has the drawback of the state space explosion as the size of the process model grows. Although approaches proposing memory efficient methods have been proposed in the literature, they are not able to properly guarantee the correct termination of the process, since they allow the user to reach deadlock states. Moreover, current implementations of declarative business process engines focus only on manual activities. Automatic communication with external applications to exchange data and reuse functionality is barely supported. Such automation opportunities could be better exploited by a declarative engine that integrates with existing SOC technologies. This work proposes a novel graph-based rule engine called REFlex that does not share the problems presented by other engines, being better suited to model declarative business processes than the techniques currently in use. Additionally, such engine fills this gap between declarative processes and SOC. The REFlex orchestrator is an efficient, data-aware declarative web services orchestrator. It enables participants to call external web services to perform automated tasks. Different from related work, the REFlex algorithm does not depend on the generation of all reachable states, which makes it well suited to model large and complex business processes. Moreover, REFlex is capable of modeling data-dependent business rules, which provides unprecedented context awareness and modeling power to the declarative paradigm.

Full textAbstract:
In order to improve the feedback an intelligent tutoring system provides, the grading engine needs to do more than simply indicate whether a student gives a correct answer or not. Good feedback must provide actionable information with diagnostic value. This means the grading system must be able to determine what knowledge gap or misconception may have caused the student to answer a question incorrectly. This research evaluated the quality of a rules-based grading engine in an automated online homework system by comparing grading engine scores with manually graded scores. The research sought to improve the grading engine by assessing student understanding using knowledge component research. Comparing both the current student scores and the new student scores with the manually graded scores led us to believe the grading engine rules were improved. By better aligning grading engine rules with requisite knowledge components and making revisions to task instructions the quality of the feedback provided would likely be enhanced.

Dissertation to obtain the Master degree in Electrical Engineering and Computer ScienceSpecialized and diversified global markets are facing a competitiveness that keeps pushing enterprises to abandon their traditional product centrism, where basically it is enough to concentrate their efforts in very narrow specialization fields and change their methods of work relying on networks of other providers that are able to fulfill their needs towards the development of complete solutions. These new methods of work, regarding the rapid change in markets and business organizations, requires new interoperability demands and complexity levels, from connection and syntax-oriented exchanges to semantic and model-oriented knowledge, which becomes very difficult for enterprises to cope with the pace of change. This dissertation proposes the implementation of a framework, based on agents and rules, to achieve solid and stable integration of solutions, via the use of a strong and formal negotiation mechanism, which will be the basis for increasing the enterprise interoperability in the supply chain for the development of solutions.

E-business provides important opportunities of trade for businesses, and the supporting business system must handle this environment efficiently. One current trend in business systems is to move business logic, such as business processes and business rules, out from the application logic and into separate support systems. The reason to make this separation is to increase the agility of the business, to make the system able to change more rapidly when the business situation changes.
This report focus on business rules enforced in business rule engines. Specific interest is on how such rule engines meet the requirements of the e-business domain. The report presents an overview of business rule engines. Five general categories of characteristics are proposed. The proposed characteristics are then used in a comparison of three business rule engines.

Operating industrial processes is becoming more complex each day, and one of the factors that contribute to this growth in complexity is the integration of new technologies and smart solutions employed in the industry, such as the decision support systems. In this regard, this dissertation aims to develop a decision support system based on an computational tool called expert system. The main goal is to turn operation more reliable and secure while maximizing the amount of relevant information to each situation by using an expert system based on rules designed for a particular area of expertise. For the modeling of such rules has been proposed a high-level environment, which allows the creation and manipulation of rules in an easier way through visual programming. Despite its wide range of possible applications, this dissertation focuses only in the context of real-time filtering of alarms during the operation, properly validated in a case study based on a real scenario occurred in an industrial plant of an oil and gas refinery

Full textAbstract:
This thesis investigates the changing boundaries of the firm. Drawing on a study of the aircraft engine industry, it explores the managerial choices faced by firms in the development of complex products. The thesis builds on the literature on the resourcebased view of the firm, and studies on inter-firm division of labour. It integrates comparative quantitative analysis and case study methods. The thesis shows that despite the increasing use of collaborative agreements, aircraft engine manufacturers maintain a broad and deep set of in-house technological capabilities. Collaborative agreements are used to complement in-house technological capabilities and as a means to maintain systems integration capabilities. The thesis also shows that the aircraft engine industry is characterised by (a) increasing product modularization, often entailing a greater division of labour across firms at the product level, and (b) active co-ordination by engine manufacturers at the technological level. These two phenomena demonstrate that the technological boundaries of the firm differ fundamentally from the boundaries of the firm as defined by make-buy decisions. Outsourcing of components does not necessarily entail outsourcing technologies. These findings challenge current managerial prescriptions that suggest that firms should focus on a few technological capabilities. They also challenge the literature that argues that modularity should inform product design as well as firms' technology bases. The thesis proposes a framework to analyse the boundaries of firms developing complex products. Focusing on their role as systems integrators, it identifies two key dimensions of systems integration: synchronic and diachronic. Synchronic systems integration refers to the range of in-house technological capabilities of engine manufacturers required to set the concept design, decompose it, co-ordinate the network of suppliers, and re-compose the engine within a given product architecture. Diachronic systems integration refers to engine manufacturers' capabilities to envisage different paths of product architectures to meet evolving customer and regulatory requirements.

Full textAbstract:
With the ascendency of data and the rise of interest in analytics, organizations are becoming more interested in the use of data to make their business processes more intelligent and reactive. BI applications are a common way that organizations integrate analytics in their processes. However, it can be days, weeks or even months before a manual response is undertaken based on a human interpreting a report. Even when information technology supports automatic responses within an organization, it is often implemented in an ad hoc manner without following a systematic framework.
In this thesis, we present a reactive performance monitoring (RPM) framework which aims at automating the link from the analytical (how well is the operational achieving the strategic) to the operational (the particular process steps implemented within an organization that determine its behavior) aspects of businesses to bypass the strategic (the high level and long term goals an organization is trying to achieve) as needed and reduce the latency between knowledge and action. Our RPM framework is composed of an architecture, a methodology, and a rule environment which permits the redaction of rules possessing relevant conditions and actions. In addition, we present an OLAP rule engine which is demonstrated to be effective in our framework where events are streamed in, reacted upon in real-time, and stored in an OLAP database.
To develop and evaluate our framework, two case studies were undertaken. The first was done using IBM technologies implementing an application made to identify patients at high risk of cancer recurrence. The second was done using open source technologies. With this second implementation, we created an application that has the goal of informing women from at risk populations of the different stages of pregnancy on a weekly basis.

Det växande önskemålet att använda ny teknik, leder till en ökning av att använda mer komplexa programvarudomäner. Dessutom kan det orsaka ett antal utmaningar, som kan lösas genom att förändra sättet som system är utformade på. Företag har tillämpat instruktioner och standarder inom sina organisationer för att minska problemen och öka samstämmigheten mellan sina program och att återanvända komponenter i olika system. Generiska eller specifika metoder kan användas för att implementera sådana system. Eftersom en specifik metod ger en bättre lösning med större fördelar och användbarhet i vissa domäner så följde denna studie denna metod. Denna studie presenterar resultatet av en explorativ fallstudie vid telekombolaget Ericsson där de utmaningar som definierar ett yttre och inre domänspecifikt språk utreddes. Möjligheterna att övergå från en manuellt byggd konfiguration för en radiobasstation till en mer automatiserad och pålitlig systemkonfiguration undersöktes. Dessutom presenteras resultatet av att utveckla ett internt och externt domänspecifikt språk baserade på företagets krav. Fördelar, tillkortakommanden, exempel på domänspecifikt språk och implementationstekniker diskuteras i rapporten. Resultatet av detta examensarbete kommer att användas som en konfigurationsdel som ingår i ett större internt verktyg inom företaget. Detta tillhandahåller en effektiv metod för att hantera komplicerade system på ett enkelt sätt.The growing request of using new technologies, leads to an increased usage of more complex software domains. In addition, it may cause number of challenges, which can be resolved by changing the way systems are designed. Companies have applied instructions and standards within their organizations to reduce the problems and increase the consistency between their software applications and reusing components in different systems. A generic or specific approach can be used to implement such systems. As a specific approach delivers a better solution with significant advantages and ease of use for particular application domains, this study followed this methodology. This study presents the result of an exploratory case study at the Ericsson telecom company where the challenges of defining an external and internal Domain Specific Language were investigated. The possibilities of how to transfer from a manually built Radio Base Station configuration towards a more automated and reliable system configuration was investigated. Moreover, the results of developing an internal and external DSL based on the company’s requirements are presented. Benefits, shortcomings, example DSLs, and implementation techniques are discussed in this report. The outcome of this thesis work will be used as a configuration part that is included in a larger in-house tool within the company. This provides an effective method to handle complicated system in a simple manner.

Route specification can be a time consuming process in flight planning, and at the same time, it should be done very diligently for the sake of a safe flight and to reach the target on time. An autonomous decision support system can save time spent on finding the most accurate and shortest route from departure to destination. Different kinds of external sources are used as input for making intelligent decisions by taking advantage of a rule based reasoning approach. In this regard, a rule based decision support concept based on Drools rule engine is proposed in order to ease the workload of pilots during route specification.Flygruttsplanering är en tidskrävande process vid uppdragsplanering. Den bör göras med stor omsorg för att garantera en säker flygning som når målet på utsatt tid.

I detta sammanhang används olika externa källor som indata och de ligger till grund för att fatta intelligenta beslut med hjälp av regelbaserat resonerande. Konceptet regelbaserat beslutsstöd är baserat på Drools regelmotor för att minska arbetsbördan för piloter under ruttplanering.

Esse cenário torna ainda mais crítico o já antigo problema de manutenção de sistemas, uma vez que as atualizações precisam ser realizadas para contemplar novos modelos de negócio, no contexto destas mudanças rápidas. Esta situação justifica a necessidade de uma abordagem que consiga capturar as mudanças nos negóios e rapidamente implementá-las nos sistemas computacionais. Considera-se que existem porções da lógica de negócio que são bastante voláteis e suscetíveis às mudanças e outras porções que são bastante estáveis e muito pouco suscetíveis às mudanças. Neste contexto, propõe-se um modelo para desenvolvimento rápido e execussão de serviços, baseado em regras de negócio. Neste modelo as porções voláteis são externalizadas como regras de negócio e as porções estáveis como serviços. A prova de conceito desta abordagem traduz regras modeladas em linguagem natural para regras no modelo da máquina de regras instanciada, que invoca os serviços
Abstract: In the current globalized world, characterized by strong Web based interactions, relationships between people, companies and government organizations are subject to changes that occur faster and faster. This scenario makes the old problem of system maintenance even more critical, as the updating of these systems needs to contemplate new business models in the context of these fast changes. This situation justifies the need for an approach that can capture business changes and quickly implement them into computational systems. It is considered that some business logic portions are quite volatile and susceptible to the changes and other portions are quite stable and less susceptible to the changes. In this context, a model for fast development and execution of services based on business rules is proposed. In this model the volatile portions are externalized as business rules and the stable portions as services. The proof of concept of this approach translates rules which are modeled in a natural language to rules in the model of the instantiated rule engine that invokes the services

Full textAbstract:
Significant developments in microprocessor and sensor technology make wirelessly connected small computing devices widely availablehence they are being used frequently to collect data from the environment. In this study, we construct a framework in order to extract high level information in an environment containing such pervasive computing devices. In the framework, raw data originating from wireless sensors are collected using an event driven system and converted to simple events for transmission over a network to a central processing unit. We also utilize complex event processing approach incorporating temporal constraints, aggregation and sequencing of events in order to define complex events for extracting high level information from the collected simple events. We develop a prototype using easily accessible hardware and set it up in a classroom within our university. The results demonstrate the feasibility of our approach, ease of deployment and successful application of the complex event processing framework.

The main objective of this thesis is to propose the control of 2D object in a remote scene, using a contextualized, collaborative and interactive multimedia. The 2D objects are mainly electronic devices. For the use case in this work, an IP camera is placed in front of the device to control. The generated stream is decoded. The front of the device is identified using image-processing techniques based on natural feature points. Then, an interactive multimedia based on the MPEG-4 binary format for scenes standard is built and broadcasted to the remote users. In order to handle collaboration, we propose a notification mechanism and communication tools to reproduce the "group awareness", which allows users to apprehend interactions between them. This approach leads us to enrich the MPEG-4 BIFS with the websocket protocol. The use of the semantic web allows us to encode expected sequences of use of the interactive multimedia. Eventually the system provides on the fly interaction adaptations to the end-user. The implementation of a proof of concept is illustrated in contributions to two open source projects : Ocelot (http://ocelot.ow2.org) and GPAC (http://gpac.wp.institut-telecom.fr)

Full textAbstract:
As samambaias do gênero Pteridium caracterizam-se pelas largas frondes e por um sistema de rizomas subterrâneos que possibilita sua rápida expansão. Apresentam elevada produção de biomassa ao longo do ano, que aumenta a incidência de incêndios, e ainda liberam substâncias químicas consideradas alelopáticas. Atualmente, são conhecidas como plantas-problema, pois vêm se expandindo e ocupando grandes áreas em diversas partes do mundo, causando impacto econômico e ecológico. Nesse contexto, este estudo teve por objetivo geral a compreensão do impacto da invasão por Pteridium arachnoideum sobre a vegetação de cerrado e a elucidação dos mecanismos por meio dos quais vem sendo lentamente revertido o processo de invasão na área de estudo. Para tanto, analisamos áreas de cerradão invadidas há mais de quatro décadas na Estação Ecológica de Assis (EEcA), no sudoeste do estado de São Paulo. Analisamos a composição florística e estrutura da comunidade em uma área invadida dentro da EEcA. Avaliamos os componentes do estrato arbóreo e regenerante da comunidade, a fim de verificar quais as espécies que conseguiram ultrapassar as barreiras físicas e químicas impostas pela presença da samambaia. Para tanto, comparamos a vegetação da área invadida com uma área adjacente não invadida, com ambiente e histórico de perturbações semelhantes. Utilizamos 100 pontos quadrantes para amostragem da composição florística e, para caracterização da estrutura da comunidade, alocamos 15 parcelas de 10 m x 30 m para amostrar o estrato superior, dentro das quais foram instaladas sub-parcelas de 2 m x 30 m para o estrato intermediário e de 2 m x 2 m para o estrato inferior. Medimos a cobertura das copas das árvores dentro das parcelas e estimamos a porcentagem de cobertura do solo por Pteridium. As espécies que conseguiram ocupar a área no início da invasão são tolerantes à sombra e com ritmo de crescimento rápido, características que possibilitaram que tais espécies ultrapassassem a barreira de samambaia e se estabelecessem na área. Já as espécies do estrato inferior se assemelham às da área não invadida, indicando que está havendo uma substituição das espécies na comunidade vegetal. A baixa densidade das árvores na área invadida diminui a competição entre os indivíduos, que, por sua vez, investem em aumento de tamanho, sendo consideravelmente maiores do que as árvores do cerradão não invadido. Essas árvores, que formam o estrato arbóreo atualmente, estão facilitando a regeneração natural de espécies arbóreas nativas e, assim, revertendo, lentamente, o processo de invasão. Testamos quais variáveis, relacionadas às funções ecológicas e aspectos estruturais das árvores de grande porte que se estabeleceram nas áreas invadidas, estão favorecendo as plantas em regeneração sob suas copas. Para tanto, amostramos os indivíduos maiores que 50 cm sob a copa de árvores sistematicamente selecionadas, segundo atributos funcionais e estruturais. Verificamos que as árvores que possuem copas mais densas e perenifólias apresentaram mais regenerantes sob suas copas. A resiliência característica do cerrado tem possibilitado que as áreas invadidas consigam se recuperar, podendo se assemelhar futuramente às áreas de cerradão da EEcA, porém muito lentamente. Ações de manejo que almejam a restauração dessas áreas mais rapidamente devem focar seus esforços na eliminação do Pteridium e/ou na introdução de espécies que possuam as características das árvores que atuam como facilitadoras da regeneração.The genus Pteridium comprises bracken species recognized by large fronds and a rhizome system that allows their fast expansion. Bracken presents an elevated biomass production throughout the year, that increases fire occurrence and release chemical compounds that are considered allelopathic. Nowadays, species of the genus Pteridium are well known as problem-species, due to their expansion and occupation of large areas around the world, causing great economic and ecological impacts. Aiming at the comprehension of bracken invasion over cerrado vegetation, we studied its impact over the plant community and, also, the slow natural regeneration process of cerrado recovery after invasion. We analyzed savanna woodland areas that have been invaded for over four decades, at Assis Ecological Station (EEcA), in southwestern São Paulo State. We analyzed the floristic composition and the plant community structure in an invaded area, compared to a non invaded patch of savanna vegetation. Components of the arboreal and regeneration strata were analyzed, in order to verify which species managed to pass by the physical and chemical barrier imposed by bracken. We assessed 100 points to assemble the floristic composition, using the quarter method, and for the community structure we used 15 plots of 10 m x 30 m to assemble the superior strata. The intermediate layer was assessed by sub-plots of 2 m x 30 m and the inferior strata using 2 m x 2 m sub-plots. We measured the canopy cover and also bracken cover inside the plots. The arboreal species first occupying the invaded area are shadow tolerant and fast growing, attributes which allowed them to overtake the bracken layer and establish. Nowadays, the invasive species has been replaced by a high number of arboreal species, the inferior strata being floristically similar to the area not invaded. The low density of adult trees in the invaded area reduce the competition among individuals that end up investing in growth, with greater size compared to those trees in the non invaded area. These large trees function as nurse trees, facilitating other species to establish under their canopies. We tested which variables related to the ecological functions and tree structure are favouring the understory, in order to comprehend the ecological processes and interactions that regulate the assembly rules of the invaded community being recovered. We assembled all individuals from arboreal species over 50 cm high growing under the projection of nurse trees canopy. These nurse trees were systematically selected, for the basis of functional and structural attributes. Understory density and richness were higher under trees with dense and permanent shadow, and that was the attribute better explaining the recovery process. The high resilience of savanna have helped the recovery of invaded areas. This process, however, has been very slow. Interventions whiling to restore those areas should be focused on bracken eradication and/or introduction of those species that can facilitate the natural regeneration.

A large number of URLs collected by web crawlers correspond to pages with duplicate or near-duplicate contents. These duplicate URLs, generically known as DUST (Different URLs with Similar Text), adversely impact search engines since crawling, storing and using such data imply waste of resources, the building of low quality rankings and poor user experiences. To deal with this problem, several studies have been proposed to detect and remove duplicate documents without fetching their contents. To accomplish this, the proposed methods learn normalization rules to transform all duplicate URLs into the same canonical form. This information can be used by crawlers to avoid fetching DUST. A challenging aspect of this strategy is to efficiently derive the minimum set of rules that achieve larger reductions with the smallest false positive rate. As most methods are based on pairwise analysis, the quality of the rules is affected by the criterion used to select the examples and the availability of representative examples in the training sets. To avoid processing large numbers of URLs, they employ techniques such as random sampling or by looking for DUST only within sites, preventing the generation of rules involving multiple DNS names. As a consequence of these issues, current methods are very susceptible to noise and, in many cases, derive rules that are very specific. In this thesis, we present a new approach to derive quality rules that take advantage of a multi-sequence alignment strategy. We demonstrate that a full multi-sequence alignment of URLs with duplicated content, before the generation of the rules, can lead to the deployment of very effective rules. Experimental results demonstrate that our approach achieved larger reductions in the number of duplicate URLs than our best baseline in two different web collections, in spite of being much faster. We also present a distributed version of our method, using the MapReduce framework, and demonstrate its scalability by evaluating it using a set of 7.37 million URLs.
Um grande número de URLs obtidas por coletores corresponde a páginas com conteúdo duplicado ou quase duplicado, conhecidas em Inglês pelo acrônimo DUST, que pode ser traduzido como Diferentes URLs com Texto Similar. DUST são prejudiciais para sistemas de busca porque ao serem coletadas, armazenadas e utilizadas, contribuem para o desperdício de recursos, a criação de rankings de baixa qualidade e, consequentemente, uma experiência pior para o usuário. Para lidar com este problema, muita pesquisa tem sido realizada com intuito de detectar e remover DUST antes mesmo de coletar as URLs. Para isso, esses métodos se baseiam no aprendizado de regras de normalização que transformam todas as URLs com conteúdo duplicado para uma mesma forma canônica. Tais regras podem ser então usadas por coletores com o intuito de reconhecer e ignorar DUST. Para isto, é necessário derivar, de forma eficiente, um conjunto mínimo de regras que alcance uma grande taxa de redução com baixa incidência de falsos-positivos. Como a maioria dos métodos propostos na literatura é baseada na análise de pares, a qualidade das regras é afetada pelo critério usado para selecionar os exemplos de pares e a disponibilidade de exemplos representativos no treino. Para evitar processar um número muito alto de exemplos, em geral, são aplicadas técnicas de amostragem ou a busca por DUST é limitada apenas a sites, o que impede a geração de regras que envolvam diferentes nomes de DNS. Como consequência, métodos atuais são muito suscetíveis a ruído e, em muitos casos, derivam regras muito específicas. Nesta tese, é proposta uma nova técnica para derivar regras, baseada em uma estratégia de alinhamento múltiplo de sequências. Em particular, mostramos que um alinhamento prévio das URLs com conteúdo duplicado contribui para uma melhor generalização, o que resulta na geração de regras mais efetivas. Através de experimentos em duas diferentes coleções extraídas da Web, observa-se que a técnica proposta, além de ser mais rápida, filtra um número maior de URLs duplicadas. Uma versão distribuída do método, baseada na arquitetura MapReduce, proporciona a possibilidade de escalabilidade para coleções com dimensões compatíveis com a Web.

This paper focuses on leadership problems and possibilities regarding creativity in a specific R&D organization. This is done with the help of a model consisting of four domains of special interest for R&D leaders. A survey in the form of personal interviews was conducted with leaders and staff members of two R&D sections in the organization. The analysis pointed towards problems on work load and stress issues. Furthermore the organizational structure of the two sections provided a discussion on optimal structural build‐up in order to maximize creativity. Trust issues arose because of the apparent use of control by upper management as described by lower level leaders and the employees. Indications showed that the trust issues put up obstacles for learning and dealing with failure. On the other hand the relationships between section management and staff were perceived as good. Also the ground works of a good creative work was laid with the trusting relationships between fellow professionals within the group.

Full textAbstract:
The present decade has seen significant progress towards realizing the vision of the Semantic Web. This progress has most often been seen in the levels of maturity reached by each layer in the architectural layers representing the Semantic Web vision. The ontology layer reached a substantial level of maturity with the OWL Web Ontology Language (OWL) being recommended by the World Wide Web Consortium (W3C) as the standard for representing ontologies on the Web. This move has triggered several other standardizations and led to interesting research results that have further strengthened the ontology layer. This has motivated the Semantic Web community to venture further towards the rules layer in the vision. One of the interesting lines of research in this context is to extend OWL with rules both syntactically and semantically and providing a sound, complete and terminating reasoning support for the extension. Our present work corresponds to this line of research.

In this thesis, we propose a new search algorithm which exploits the association rules to enhance the search performance. When users input the keywords for query, our model will find more related expansion words for the users from Google and Yahoo. Our model can handle not only a simple word but also phrase problems in bilingual language queries, English and Traditional Chinese. We can easily delimit a word by blanks in English, but in the contrast Chinese words do not have obvious delimiters. Since a phrase is composed of words, there should exist a method to consider whether a word should be concatenated with consecutive words to become a phrase. We treat a word as an item in the transaction database. We then compute the confidence value of one term and its following terms to determine whether they can be concatenated to become a phrase. If the confidence value is greater than the given threshold, it will be treated as a large item set to represent the consecutive appearance in an article. In addition, the proposed system provides another function for users, i.e., personalized service. Applying the gray relational method, our system can infer users’ preferences according to the log files. By utilizing the state-of-the-art technique, data mining, the system can extract the association rules to be the foundation of recommendation. Whenever users login the website, browse and click the search results, our system can automatically recommend personal-interesting information. Detailed simulation results are given to illustrate the applicability of the presented work.

In the age of information explosion, it is easy and fast to search information on the Internet. It is convenient to use mobile technology. The keywords become more important because people use them to search information on searching engines. However, the price of keyword advertising is usually unaffordable for general companies. This thesis studies how to increase the exposure of specific website by embedding keywords on the webpage, which can accelerate the speed of finding specific website without keyword advertising. This research embeds keywords of specific company on the webpage and develops an optimum rule by putting several combinations of keywords on a webpage and finding the most efficient combination. The developers of the website can use this rule to embed the keywords they need, as the result, people can find this website quickly. So far, we already list thirteen rules and test for three months. Finally, we are able to obtain the highest exposure and ranking by mixing common and uncommon keywords

Full textAbstract:
Software systems are widely used in people daily routines and responsibilities, therefore, systems need to be developed rapidly and efficiently. Domain specific languages (DSLs) are languages that are applied to a specific application domain. Since DSLs provide notations and constructs adapted to a particular domain, they offer gains in expressiveness and ease of use when compared with general-purpose languages (GPLs). Therefore, one of the most important steps in the Software Language Engineering is the evaluation of the languages produced, with the end-users, since the risk of building inappropriate languages, that often do not fit the end users, may decrease productivity. Although DSLs evaluation is one of the most important steps in development process, Software Language Engineers tend to relax the experimental validation of their products due to several reasons like costs (time, means, money, the number of people required, etc.) and required know-how associated with it. The lack of systematic approaches and guidelines to evaluate DSLs, and a comprehensive set of tools may explain this shortcoming in the current state of practice. The Usability Driven DSL development with USE-ME (USE-ME) approach, developed in NOVA-LINCS, "promotes the quality in use of DSLs by building a
framework that leverages usability as a main concern". The feedback of the pilot studies was that despite the approach was "more or less easy" to understand it was not easy to model, since "there were too many steps to follow" and the framework did not provide a "guided cycle". So, in order to improve the system usability and the quality of the models produced with USE-ME, we developed a new version of the framework with validation rules implemented with Eclipse Validation Language (EVL) that guide, suggest and validate the Software Language Engineer actions throughout the development process. The validation rules were designed in such a way that the tool educates the user about the process, so that the user makes the best decision regarding his DSL evaluation. We performed two experiments, with different goals. The main goals of the first one was to analyse the effect of validation rules on the USE-ME framework, with respect to their impact on the System Usability Scale, and on the Model Correctness of USE-ME models. We analysed the results and we found evidences of improvements on the System Usability Scale, and on the Model Correctness of models, brought by the addition of the rules. The second experiment was conducted with a research team from Ege University, in Turkey. The main goal of this experiment was to perform a guided evaluation on a DSL related with Multi-Agent Systems, SEA-ML. Since the number of participants was low we cannot draw conclusions regarding this experiment.
Despite the significant results from the first experiment further evaluation on the
new version of the framework is necessary, this time, with more experienced users and
with more complex exercises. With this new experiment, we can compare the results and improve the USE-ME framework.

Context-awareness is one of the key requirements for intelligent systems in ubiquitous computing and smart space. A knowledge-based context-aware system infers the relevant services from its knowledge base, or KB, in which contexts are represented. To maintain relations between context KB and the physical environment synchronously, this thesis describes a logic-based model that attempts to management dynamic contexts stored in the KB from which a context-aware system can infer context-triggered actions and high-level contexts. By applying STRIPS representation and assumption, we model context-aware reasoning formally into a series of situation-driven actions. A context-aware rule engine called or CARE is developed based on the proposed reasoning model. To support making context-aware reasoning and building context-aware applications, CARE provides a systematic way to manage contexts in the KB. It utilizes a forward chaining rule engine called Jess to process rules, facts, and contexts. Three context-aware applications developed with CARE are described in this thesis to demonstrate the capabilities of context-aware reasoning, the design of context-aware applications, and the software support by CARE. All three applications are covered in healthcare domain. The first targets context-aware access control in pervasive healthcare environment. The second introduces a context-aware services integration system for assisting elder care in future smart home. The third aims to speedup the process of emergency visit by designing several location-aware notification services for medical members in an emergency department.

Gateway is connected with electrical equipment components and sensors, and transfer data between electrical equipment and server. We built a distributed management method to manage massive electrical equipment. We built a general rule grammar according to BNF. Users can build rule according to our rule grammar so that system can evaluate device statues which reported from sensors, and send control command to operate electrical equipment.

The average makespan of aircraft engine maintenance directly influences the availability of aircrafts in an aircraft service organization. The study takes a military aircraft engine (M53-P2) maintenance problem as an example, and the objective is to improve the schedule of the I/L engine maintenance activities. Two improvement policies are proposed: one reallocates the human resources and the other applies the DBR (Drum-Buffer-Rope) scheduling rule in the theory of constraints. The aircraft engine maintenance problem is a complex task. An engine consists of many modules and each module contains a lot of parts. An activity is the maintenance work on an individual module. Nevertheless, for many activities, duration depends on the extent of the component damages, which is usually uncertain before the module is disassembled. Thus simulation method is an appropriate tool to cope with this problem. Generally speaking, the maintenance work can be classified into three levels: organizational level maintenance, intermediate level maintenance, depot level maintenance. Our study focuses on the intermediate level maintenance. The goals of the two proposed improvement policies are to shorten the maintenance makespan and increase the repaired or maintained engine throughput. Policy one adjusts the workstation manpower while holding the total human resources fixed. Policy two uses the DBR rule. Simulation tool ARENA software is used to simulate the scenarios for the two policies based on the current data. Our experimental result indicates that both policies achieve improvement on the annual throughput of aircraft engines, but the DBR rule outperforms the other one. As a result, we suggest that DBR rule be used for the aircraft engine maintenance problem.

An ideal concept of smart home should provide proper service in accordance with user's preference. In addition, it should ensure appropriate responses to context change in the home environment. To achieve these objectives, this paper proposes a Context Aware Service Platform (CASP) with reasoning mechanism for providing a personalized smart home. This paper designs a rule-based template which defines the relation between environment context and service. The core of the platform, rule-based engine, suggests a reasoning service which reacts to context change in environment. Demonstration shows that the appropriate service can be configured in the configurable rule-based engine and later automatically invoked by considering the user’s preference setting, sensor status, user activity, and presence time from smart home environment.

In this thesis, we propose a solution to combine Workflow Engine which is implemented by COM , Database’s Stored Procedure and Database’s Extended Stored Procedure,…,etc to perform business process automatically. The features of our system are as follows: ● Using COM technology to implement functions of Workflow Engine. These functions include State-Searching, Rule execution and Receipting and Assigning. ● Using the Extended Stored Procedure to integrate the Database with the COM. ● Using Meta Stored Procedures to create triggers for each kind of document ● Using a Database’s Table to simulate a file system of user in workflow, and this file system can be used for receipting documents of workflow. ● Providing a Electric-Form Designer to design electric documents which is delivered in workflow. ● WorkFlow Designer is used to build system tables which are used by workflow and produced triggers for each kind of document and Workflow’s rule.

In a traditional game engine with polling model, the whole exhibit is concerned with drawing sprites and controlling role. To improve this problem, we propose an engine which is mixed with event-driven and looping model. We also design the role as a component, so there is a benefit of reuse. The modifiable rule is composed with an instruction set and stored in a database file which is accessible with ADO. The game engine we finished is made of ActiveX control, DirectX components, and COM class. Our game engine contains an Animation & Interaction Engine(AIE) and a GameWorld. The former is an out-process ActiveX class module with looping model and its primary functions are drawing sprites, collision detecting and time handling. The GameWorld is the major part of the system. It is an event-driven model which contains a GameWorld engine, a rule engine, event handlers and all role components. So, our game engine is event-driven and periodicity. Besides, for network, we use a method that needs the beginning line and the number of actions in the action table. This may reduce the overhead of communication traffic. Since we use component-based design and our game engine is mixed with event-driven model and looping model, our programs are reusable and flexible. Furthermore, the whole code is implemented by Visual Basic. It may take the convenience of Visual Basic. With our game engine, the game design is just focus on constructing the game rule, the role components, and the event handles. The most detail things such as drawing sprites and handling network may be simplified. According to these methodologies, we may anticipate that the productivity is increased and the debugging cost is reduced.

Due to the deterioration of global economy, the growth of Taiwan national defense finance has been highly restricted. In the meantime, Taiwan armed force face the dilemma to reorganize the military structure while facing the budget shortage. In response to the down-sizing in military scale and limited support, naval vessels often encounter contingency missions to protect our territorial seas. Under these diverse missions, decision makers usually intend to know how to optimally utilize the resource of naval vessels with limited budget? The Navy's ongoing efforts to achieve the goal is to explore the best maintenance efficiency in the life-cycle and make sure the availability and utilization of naval vessels. MTU diesel engine, widely used in naval vessels and driven by dual axis propulsion, is highly associated to the availability of fleet which support combat readiness training and other tasks while often sailed to the walrus harsh sea. Hence, the proper maintenance of equipment may lead to the success of mission. The repair or maintenance project of the host system is performed by the technical order defined by the manufacturer. Although most of the maintenance task followed the preliminary maintenance project, the test data cannot be effectively used to analyze the fault time of the component. Besides, even with mature technical analysis, it still lacks of using scientific method to effectively analyze systems or components with high frequency of equipment failures. This study aims to uses the historical maintenance dataset of the MTU engine and the association rule analysis algorithm to construct a analytics model. The proposed framework can infer equipment failure and operation management rules, reduce the frequency of equipment failure repairs and raise equipment availability and reduce maintenance costs.
