Model-Driven Development (MDD) is proposed to reduce the semantic gap between problem and solution/implementation domains. Some tools are used, and the code generator is commonly used in this context. These generators are often implemented using templates. A Reference Implementation (RI) favoring the development/ maintenance of software facilitates this implementation’s types. However, RI requires a code migration process which consists in artifacts’ synchronization, and it is responsible for 20% to 25% of the time spent on development. The literature has no describe automatic solutions, but the group that this reaserch was included has develop tools that automate this process and reduce the time spent on some tasks. But each task has a different performance in relation to time spent, so automation of some tasks can be disadvantageous. Few reports describe such tasks and which ones are capable of automatic code migration. The aim of this study is to investigate the maintain and evolution process to identify and describe the types of maintain and evolution tasks that are essentially. Based on this study, a method (MME-MDD) that drives the developer during that proccess to guide the developer during the realization of each task, with the aim to maximize the benefits of this approach. The MME-MDD was validated by a case study and a empirical study and the method showed effective in most of tasks. In addition, studies show that using the proposed method brought a gain in the quality of the source code.
O MDD (Model-Driven Development) tem como proposta a redução da distância semântica entre os domínios problema e solução/implementação. Para isso, são utilizadas algumas ferramentas, sendo o gerador de código comumente usado neste contexto. Os geradores de código são frequentemente implementados com a utilização de templates. Para facilitar este tipo de implementação, usualmente é empregado uma Implementação de Referência (IR), favorecendo a evolução/ manutenção do software. Contudo, a IR traz a necessidade do processo de migração de código, que consiste na sincronização entre o seu código-fonte e os templates, sendo que este é responsável por 20 a 25% do tempo gasto no desenvolvimento. Na literatura não há relatos de solução automatizada, mas o grupo no qual esta pesquisa se insere vem desenvolvendo ferramentas que automatizam este processo e reduzem o tempo aplicado em algumas tarefas testadas. Porém, cada tarefa tem um desempenho diferente em relação ao tempo gasto e, portanto, a automação de algumas tarefas pode ser desvantajosa. Existem poucos relatos na literatura descrevendo tais tarefas e quais são os passos necessários para realizá-las. O objetivo deste estudo foi a investigação do processo de manutenção e evolução de sistemas baseados em MDD com a finalidade de identificar e descrever os tipos de tarefas de manutenção e evolução. Com base nesse estudo, foi elaborado o método MMEMDD que conduz o desenvolvedor durante o processo de manutenção e evolução de sistemas, visando guiar o desenvolvedor durante a realização de cada um dos tipos de tarefas, com o intuito de maximizar os benefícios da utilização dessa abordagem. O método foi validado por meio de um estudo de caso e um estudo experimental, sendo que o método se mostrou efetivo em grande parte das tarefas testadas. Além disso, os estudos apontaram que a utilização do método proposto trouxe ganho na qualidade do código-fonte.

Abstract:
For complex traits, population genetic studies ask: to what extent do genetic variation and environmental variation influence, determine and predict phenotypic variation? More specifically, researchers ask two questions. First, how much of the phenotypic variation is genetic in origin? Second, if the genetic component of a trait has been ascertained, then by what mechanisms do the causal variants contribute to the genetic variation that impacts on the phenotype? Previous studies have indicated a polygenic structure for many complex traits, which means that the genetic variation in those traits is the result of the cumulative effect from hundreds or even thousands of genetic variants. To further decipher the polygenic genetic architecture of a complex trait, genetic studies aim to identify the number, the location in the genome, and the distribution of the effect sizes of causal variants, as well as their individual and interacting effects. Linkage analysis and genome-wide association studies (GWAS), either based on single variants or sets of variants categorized by functional annotations, can be applied to map the potentially causal variants in the genome. The identification of disease-associated loci, however, is only the starting point in identifying causal variants. Causal variants are usually difficult to distinguish from the large number of variants in linkage disequilibrium (LD) within the associated loci, and may be in incomplete LD with genotyped variants. Computational prediction integrated with multi-level ‘Omic’ data will help the prioritization of candidate causal variants, which then become important targets for experimental validation (Chapter 1). Major depressive disorder (MDD) is a complex trait, contributes the second most important burden to global disease. Both genetic and environmental components have been suggested for this disorder in previous studies, although a clear partitioning of the contribution of each component and the identification of major contributing components is yet to be achieved. In efforts to map causal genetic variants, genome-wide association studies of MDD have identified few significant associations so far. The polygenic architecture combined with the widespread clinical and genetic heterogeneity of MDD between populations may impede the identification of causal variants (Chapter 2). In this thesis, I will present three studies; the first study estimated the proportions of the phenotypic variation that are genetic or familial environmental in origin in two depression definitions(chapter 3), followed by two studies where distinct (non- GWAS) methods were used to identify candidate causal genetic variants for MDD (chapter 4,5). In detail, in chapter 3, a variance component analysis was applied to GS:SFHS (Generation Scotland: Scottish Family Health Study) to investigate the relative genetic and environmental contributions to diagnosed major depressive disorder (MDD) and self-declared depression (SDD). Models for MDD and SDD that simultaneously included genetic and environmental effects suggested that narrow-sense heritability could be inflated by the environments shared by nuclear family members. The most parsimonious models selected for both MDD and SDD included SNP and pedigree-associated genetic effects and the effect of the common environment of couples. In chapter 4, I integrated pathway analysis and multi-level regional heritability analyses in a pipeline designed to identify MDD-associated pathways. The pipeline was applied to two independent GWAS studies (GS:SFHS and PGC1-MDD). The NETRIN1 signalling pathway showed the most consistent association with MDD across the two samples. Polygenic risk scores (PRSs) from this pathway showed predictive accuracy better than whole-genome PRSs when using AUC statistics, logistic regression and the linear mixed model. In chapter 5, genome-wide Haplotype-block-based regional heritability mapping (HRHM) was applied to identify haplotype blocks significantly contributing to MDD. A haplotype block across a 24kb region within the TOX2 gene reached genotype-wide significance in GS:SFHS. Single-SNP and haplotype based association tests were used to localize the association signal within the region identified by HRHM, and demonstrated that five out of nine genotyped SNPs and two haplotypes were significantly associated with MDD. The results were replicated in the UK-Ireland group in PGC2-MDD. The brain expression of TOX2 and brain-specific LncRNA RP1-269M15.3 were also significantly regulated by MDD-associated SNPs within the identified haplotype block. The three studies highlight the value of the application of multiple population genetics and bioinformatics methods to multiple family-based and population-based cohorts in identification of risk factors for MDD.

Abstract:
O surgimento e o uso crescente de novas tecnologias têm levado à produção e armazenamento de grandes volumes de dados biomédicos. Tais dados são provenientes de diferentes técnicas, armazenados em formatos de representação diversos e utilizados por diferentes ferramentas. Esta heterogeneidade representa um empecilho ao maior uso desses dados em abordagens integrativas de pesquisa como, por exemplo, a biologia sistêmica. Neste cenário, artefatos de modelagem conceitual, tais como ontologias, têm sido utilizados para organizar e integrar dados heterogêneos de uma forma coerente. A OBO Foundry representa, atualmente, o maior esforço no desenvolvimento de ontologias biomédicas de forma colaborativa. Dentre as ontologias desenvolvidas pela OBO Foundry, destaca-se Ontologia de Relacionamentos (RO-OBO). A RO-OBO provê definições formais para um conjunto de relacionamentos de propósito geral utilizados nas ontologias biomédicas e busca promover a criação de ontologias mais corretas e integráveis. Um perfil UML foi proposto para representar formalmente o conjunto de conceitos e relacionamentos existentes na RO-OBO. Este perfil permite desenvolver modelos UML utilizando os conceitos presentes nesta ontologia, bem como torna possível o desenvolvimento de suporte à validação sintática dos modelos criados em relação a um conjunto de restrições formalmente definidas. Adicionalmente, percebe-se na literatura que o suporte à integração de modelos UML e ontologias OBO, em particular as ontologias representadas na linguagem OBO File Format, é limitado. Neste sentido, este trabalho teve como objetivo geral investigar o suporte ao desenvolvimento de ontologias biomédicas na linguagem UML. De forma específica, investigou-se o desenvolvimento de um editor gráfico, chamado OBO-RO Editor, para o suporte à construção de ontologias utilizando o perfil UML proposto, bem como a integração de ontologias desenvolvidas utilizando UML e ontologias desenvolvidas na linguagem OBO File Format. De forma a atingir nossos objetivos, uma arquitetura de referência foi definida e um processo de desenvolvimento orientado a modelos foi utilizado. A arquitetura definida é composta por uma série de artefatos inter-relacionados os quais são transformados (semi) automaticamente em código de aplicação, possibilitando a obtenção de ciclos de desenvolvimento mais rápidos e confiáveis. O OBO-RO Editor disponibiliza um conjunto de elementos gráficos de modelagem definidos a partir do perfil UML proposto, bem como provê mecanismos para a validação sintática (semi) automática de uma ontologia desenvolvida segundo as restrições definidas neste perfil. Adicionalmente, o OBO-RO Editor também provê suporte à integração de modelos UML a outras ontologias da OBO Foundry, permitindo o reuso e o desenvolvimento menos propenso a erros de ontologias no domínio biomédico.
The development and increasing use of new technologies has resulted in the production and storage of a huge amount of biomedical data. These data are produced using different techniques, stored in different formats and consumed by different (software) tools. This heterogeneity hinders effective data usage in integrative research approaches, including systems biology. In this scenario, conceptual modeling artifacts, such as ontologies, have been used to organize and integrate heterogeneous data in a coherent manner. Nowadays, the OBO Foundry represents the most important effort for the collaborative development of ontologies in the biomedical domain. The OBO Relation Ontology (OBO-RO) can be considered one of the most relevant ontologies in the domain. This ontology provides formal definitions for a number of general purpose relationships used in biomedical ontologies, thus facilitating the integration of existing ontologies and the development of new ontologies in the domain. An UML profile has been proposed to formally define the different types of concepts and relationships provided by the OBO-RO. This profile enables the creation of UML models using such concepts and allows the development of support for the automatic validation of these models based on formal constraints. Additionally, the support for the integration between UML models and OBO ontologies, particularly ontologies represented using the OBO File Format, is limited. In this sense, this project aimed at investigating the support for the development of biomedical ontologies using UML. In particular, we investigated the development of a graphical editor, named OBO-RO Editor, to support ontology development using the proposed UML profile. Additionally, we also investigated the integration of ontologies developed using UML and ontologies developed using the OBO File Format. In order to achieve our goals, we have defined a reference architecture and a model-driven development process. The reference architecture consists of a number of related artifacts that are transformed to application code (semi) automatically. Such characteristic allowed us to obtain faster and more reliable development cycles. The OBO-RO Editor provides a number of graphical elements defined in the proposed UML profile for the modeling of biomedical ontologies and support the (semi) automatic syntactic validation of such ontologies against the contraints defined in the profile. Additionally, OBO-RO Editor also provides support for the integration of developed UML models and other OBO ontologies, allowing the reuse and the accurate development of biomedical ontologies.

The model driven software development with MDA requires the transformation of system models, initially specified in high-level and platform independent, into platform dependent models. The Model Driven Architecture (MDA) presents an architectural guided modeling technique, using mappings and transformations that must be applied in the system models according system platforms. This work presents the FOMDA (Features-Oriented Model-Driven Architecture) approach, to help developers specifying models and managing transformations using the MDA technique. The FOMDA approach combines Features Model and MDA in an environment where developers can represent system characteristics with features and map them to transformation code that is responsible to generate the final application. This work also presents a case study using FOMDA to assist the development on an embedded real-time system.

Abstract:
Este trabalho tem por objetivo propor a utilização de soluções pré-definidas e comprovadas na abordagem MDA, auxiliando o desenvolvedor na resolução de problemas recorrentes ao desenvolvimento de software. A utilização destas soluções pré-definidas leva a um aumento de produtividade no contexto MDA e na geração de software baseado em boas práticas. Para que este objetivo seja cumprido, é empreendida uma análise sobre o MDA e sobre como operacionalizar as transformações entre modelos. Também é empreendida uma análise sobre o suporte fornecido pela UML e sobre reutilização em desenvolvimento orientado a modelos. Por fim este trabalho apresenta partes de uma aplicação protótipo, construída para ser uma prova de conceito de código gerado através da combinação de UML e soluções pré-definidas.

Model-Driven Development (MDD) é um paradigma que usa modelos como o principal artefato no processo de desenvolvimento de sistemas. Isto é, neste paradigma, modelos não são apenas artefatos de documentação, pois devem corresponder a códigos executáveis. Em projetos de Banco de Dados Espaciais (BDE), existem várias linguagens de modelagens (e.g., OMT-G, MADS, GeoProfile e UML-GeoFrame), as quais permitem representar características espaciais (e.g., Múltiplas Representações e Relacionamento Espacial) por meio de uma ferramenta do tipo Computer-Aided Software Engineering (CASE). Embora essas linguagens sejam bem exploradas e difundidas na literatura, constatou-se que estas têm deficiências para modelar e implementar integridade espacial a partir de entidades com múltiplas representações. Assim, de modo a avançar o estado da arte sobre projeto de BDE, este trabalho faz uma análise dos principais trabalhos relacionados, e, de modo a contribuir para superar as deficiências encontradas, propõe uma extensão espacial para a linguagem de modelagem Enhanced Entity Relationship (EER). Essa extensão é implementada na ferramenta EERCASE e avalidada por meio de uma análise comparativa com os principais trabalhos relacionados, evidenciando seus pontos fortes e fracos.
Model-Driven Development (MDD) is a paradigm that uses models as the primary artifact in the systems development process. That is, in this paradigm, models are not only documentation artifacts, since these should be the executable code. In Spatial Databases projects (SDB), there are several modeling languages (e.g., OMT-G, MADS, GeoProfile and UML-GeoFrame), which allow to represent spatial characteristics (e.g., Multiple Representations and Spatial Relationship) by means of a tool type Computer-Aided Software Engineering (CASE). Although these languages are better exploited and widespread in the literature, it was found that they have deficiencies in modeling and implement spatial integrity from entities with multiple representations. Thus, in order to advance the state of the art in SDB project, this paper analyzes the main works related and, in order to contribute to overcome the deficiencies, proposes a spatial extension for modeling language Enhanced Entity Relationship (EER). This extension is implemented in tool EERCASE and evaluated through a comparison with the main work related, highlighting their strengths and weaknesses.

No mundo globalizado e competitivo, a sobrevivência de uma organização está relacionada a atrair e, principalmente, manter clientes (consumidores) através da prestação de serviços de qualidade. Atualmente, a forma mais usual de comunicação direta entre as organizações e seus (possíveis) clientes é através de aplicações baseadas na Web. Entre as vantagens deste tipo de aplicação estão a disponibilidade em tempo integral (24/7/365) e a facilidade de acesso, tendo em vista que o requisito inicial é apenas um computador com acesso à Internet. No contexto da disciplina de Engenharia de Software, as aplicações Web possuem características específicas que as diferem de aplicações tradicionais, especialmente no que se refere à interação com os usuários, e que devem ser consideradas adequadamente no processo de desenvolvimento. Entretanto, os processos de software tradicionais são dirigidos à funcionalidade e a parte do sistema responsável pela interação com os usuários é tratada com menor ênfase usualmente apenas na etapa de Implementação, ocasionando deficiências no produto e insatisfação dos usuários quanto ao uso do sistema. Neste cenário, este trabalho apresenta o método WE4UIV (Web Engineering User Interaction View), dirigido a modelos e baseado em componentes, cujo propósito é tratar os aspectos relacionados à visão de interação com os usuários de aplicações Web, nos níveis de análise e projeto, de modo a fornecer subsídios para orientar a etapa de Implementação. Além disso, visando acelerar e tornar menos manual a etapa de Implementação, este trabalho também apresenta uma ferramenta integrada a um ambiente de desenvolvimento para geração de código fonte a partir de artefatos de projeto descritos em UML. A abordagem apresentada neste trabalho pressupõe melhorias quantitativas no processo de desenvolvimento da visão de interação com os usuários, especificamente redução do tempo da etapa de Implementação e do índice de trabalho adicional causado por solicitações de mudança. A abordagem proposta é validada através de um processo de experimentação no contexto de um projeto real de desenvolvimento de software

Abstract:
O desenvolvimento orientado a modelos (Model Driven Development - MDD) é uma abordagem que tem ganhado cada vez mais espaço na indústria e na academia, trazendo grandes benefícios, como o aumento de produtividade. Uma forma de se trabalhar usando MDD em equipe é usando uma IDE (Integrated Development Environment) associada a um sistema de versionamento. Entretanto, trabalhar colaborativamente usando uma IDE associada a um sistema de versionamento pode trazer algumas complicações para o desenvolvimento como: conflitos de modelos, documentação descontinuada, dificuldades por parte dos interessados em usar sistemas de versionamento, etc. Nesse contexto, este trabalho propõe uma abordagem de uso de wiki para desenvolvimento de MDD, de modo que o desenvolvedor seja capaz de criar modelos, gerar código fonte, compartilhar e versionar os modelos e ainda documentar colaborativamente, de maneira mais simples e fácil do que abordagens tradicionais. Isso possibilita que mais usuários não desenvolvedores possam participar mais no processo de desenvolvimento e ainda permite o aumento de produtividade. Para tentar evidenciar de que é possível uma wiki ser usada para desenvolver software, foi criada uma Domain Specific Language - DSL em uma wiki e foram realizados três estudos de caso: um com estudantes do ensino médio e que representam os não desenvolvedores, um com quatro alunos de pós-graduação com experiência de desenvolvimento na indústria e o último estudo de caso foi realizado com 48 participantes entre desenvolvedores e alunos de pósgraduação em Ciências da Computação. Os estudos de caso mostraram que é viável usar uma wiki para desenvolvimento, que não desenvolvedores se adaptam bem à abordagem e que 86% dos desenvolvedores usariam a abordagem proposta se tivessem que trabalhar com MDD. Os estudos de caso também levantaram as principais barreiras para aumentar a aceitação da abordagem. Com isso, este trabalho apresenta além de uma abordagem relativamente inédita na literatura, resultados sobre uso de sistemas de versionamento, de IDEs e de desenvolvimento colaborativo
The Model Driven Development (MDD) is an approach that has gained more space in industry and academia, bringing great benefits such as increased productivity. One way of working in teams with MDD is using an IDE (Integrated Development Environment) with a versioning system. However, to collaboratively work with an IDE and a versioning system may have implications and problems for the development as: conflicts of models, documentation discontinued, difficulties for stakeholders to use versioning systems, etc. In this context, this work proposes an approach to use a wiki to develop MDD, so that the developer is able to create models, generate source code, sharing and versioning models and also to collaboratively document, in a more simple and easy way than the traditional approaches. This enables non developers can participate more in the development process and also allows increasing productivity. To try to show that a wiki can be used to develop software, we created a Domain Specific Language (DSL) in a wiki and were performed three case studies: one with high school students and represent the non developers, another one with four graduate students with experience in software development in the industry, and the last case study was conducted with 48 participants among developers and graduate students in Computer Science. The case studies showed the feasibility of using a wiki for development, that non developers adapted well to the approach and 86 % of the developers would use a wiki to develop MDD. The study also raised the main barriers to increase the acceptance of the approach. Therefore, this work presents also a relatively new approach in the literature and results on the use of versioning systems, IDEs and collaboratively development

Abstract:
Com o aumento do uso das atividades de modelagem em processos de desenvolvimento de software, a participação de pessoas com deficiência visual em tais processos requer esforços dedicados para que os modelos sejam passíveis de entendimento, caso contrário essa participação fica comprometida. Os modelos são em sua maioria visuais e, portanto, seu processo de construção requer o posicionamento de elementos no espaço do documento por meio de um dispositivo de apontar, como o mouse, e sua leitura requer o uso da visão, uma vez que os diagramas são compostos não apenas por textos, mas também por elementos visuais como retângulos e arcos conectando-os. Neste contexto, o objetivo deste projeto foi desenvolver uma técnica textual para representação e interação com diagramas que possibilite que pessoas com deficiência visual sejam capazes de colaborar em projetos de software, tanto utilizando uma abordagem de desenvolvimento orientado a modelos, quanto em uma abordagem de desenvolvimento tradicional. Para atingir o objetivo proposto foi desenvolvido um protótipo de uma ferramenta Web, a AWMo (lê-se letra a letra: A-W-M-O), a partir da qual a edição de modelos pode ser realizada por meio de duas visões equivalentes: uma visão gráfica, na qual o engenheiro de software poderá inserir novos elementos no diagrama, posicioná-los e definir suas propriedades de modo visual; e uma visão textual, na qual o engenheiro de software pode inserir novos elementos, propriedades e relacioná-los utilizando uma gramática textual. Um estudo de caso foi conduzido para avaliar sua eficácia e os resultados mostraram que a linguagem textual desenvolvida não representa uma barreira para a utilização da abordagem proposta pela AWMo. Os resultados sugerem que a AWMo é uma opção viável para facilitar o acesso de deficientes visuais a modelos de software, ajudando a promover a colaboração e comunicação efetiva e de maneira independente entre usuários com e sem visão para atividades de modelagem de software
With the growth of modeling activities in software development processes, the participation of visually impaired users requires dedicated efforts so that the models are capable to be understood, otherwise this participation is compromised. The models are mostly visuals and, therefore, their construction process requires the positioning of elements in the document space with a pointing device, like the mouse, and their reading requires the use of vision, since the diagrams are composed not only by text, but also by visual elements such as rectangles and arcs connecting them. In this context, the goal of this project was to develop a textual technique to represent and interact with diagrams to allow visually disabled people to collaborate in software development projects, either using an model driven development approach or a tradicional development approach. To achieve the proposed goal, a prototype Web tool called AWMo was developed. The prototype allows the edition of models to be done in two distinct views: a graphical view, where the software engineer is able to insert new elements and define their position in a visual and traditional way; and a textual view, where the software engineer is able to insert new elements, their properties and relationships using a textual grammar. A case study was conducted to evaluate the efficacy of the approach and the results show that the textual language developed did not posed itself as a barrier to the use of the AWMo. The results suggest that AWMo is a viable option to allow the access of the visually impaired to software models, promoting collaboration and effective communication between sighted and blind users in software modeling activities, but most importantly, in an independent way

Nos últimos anos, o paradigma de desenvolvimento de software dirigido a modelos tem se consolidado e ganho popularidade. Desta forma, um produto de software pode ser obtido através de transformações dos modelos de mais alto nível de abstração para os de mais baixo nível, sendo essa transformação guiada por metamodelos. Por exemplo, requisitos iniciais de um sistema de software podem ser transformados em modelos conceituais deste sistema. Observamos que, tanto a abordagem de modelagem de requisitos i* (iStar) como a linguagem de modelagem conceitual OO-Method (OO-M), têm ganho notoriedade no âmbito acadêmico e industrial. Nesta dissertação, estamos interessados em transformar modelos de requisitos iniciais, descritos em i*, em modelos conceituais especificados em OO-Method. Em particular, investigaremos como os requisitos não-funcionais (NFR) de produto, relacionados a softgoals internos a um ator sistema do i*, poderão ser analisados nas abordagens que transformam modelos de requisitos i* em modelos conceituais descritos em OO-Method. Erros e omissões dos requisitos não-funcionais têm impacto bastante negativo na qualidade do produto final: custos elevados de correção pós-implantação e inviabilização do projeto de software. Esses requisitos estão entre os mais caros e difíceis de corrigir. Nesta dissertação, é apresentada a proposta OOM-NFR, que analisa os softgoals internos a um ator sistema em modelos i* para verificar conflitos, prioridades e satisfação dos mesmos. Além disso, com base nos metamodelos i* de origem e OO-Method de destino, a proposta especifica um processo de transformação contendo regras que convertem uma instância de um modelo i* em outra instância do modelo OO-Method. Com o processo OOM-NFR, o modelo OO-M gerado reflete as prioridades dos softgoals especificados em i*. Para ilustrar e validar a proposta, foi concebido um exemplo de uma aplicação baseada num sistema real, utilizando-se a linguagem de transformação de modelos Query/View/Transformation (QVT) para automatizar e implementar essas transformações.

Abstract:
Early onset depression is associated with high recurrence rates later in life. Recurrent depressive episodes during childhood may be particularly problematic, if additional episodes have a scarring effect that hinders healthy development. Distinguishing between first onsets and recurrences has been useful in understanding adult depression. This distinction has seldom been examined in pediatric depression, in part because it is difficult to enroll adequate samples of children with recurrent depression. We conducted archival analyses of carefully-diagnosed pediatric probands with depression first onset between ages of 4 and 12. Probands who reported one depressive episode (N = 435) were compared with probands who reported two depression episodes (N = 115) on clinical (treatment, comorbidities), psychosocial (negative life events (NLEs), parental psychopathology) and emotion regulation measures. Based on previous findings in older adolescents and adults, we hypothesized that probands with two MDEs will have higher comorbidity, parental psychopathology, more NLEs, and higher maladaptive emotion regulation scale scores than probands with one MDE. Surprisingly, probands with one and two MDEs were indistinguishable on psychological and pharmacological treatment variables. As expected, probands with two MDEs had lower age of first onset, higher maladaptive emotion regulation scores, higher rates of comorbid anxiety and reported more NLEs than probands with one MDE. Probands with two MDEs also spent a longer total time in episode; group differences remained after controlling for time spent depressed. Distinguishing between first onsets and recurrences is meaningful in pediatric depression.

Abstract:
Objetos de aprendizagem (OA) compõem uma das abordagens adotadas para tratar a crescente complexidade da educação com auxílio de computadores, promovendo o reúso e a qualidade de materiais didáticos. Tais benefícios podem ser ampliados ao incluir questões de projeto instrucional e associá-las às características multimídias e interativas dos dispositivos computacionais, sistematizando-se a produção de objetos de aprendizagem. Nesse contexto, esta tese define uma abordagem para o desenvolvimento de objetos de aprendizagem multimídias e interativos considerando o cenário de televisão digital. Essa abordagem, denominada LOD (Learning Object Development) consiste de um modelo de processo ou processo-padrão para desenvolvimento de objetos de aprendizagem (SPLOD Standard Process for Learning Object Development), a partir do qual se define um processo (LODP Learning Object Development Process) adequado para a construção de objetos de aprendizagem como recursos educacionais abertos (análogos a software livre); de um método de desenvolvimento dirigido a modelos, denominado LODM (Learning Object Development Method), compreendendo a modelagem conceitual, instrucional e de interação do objeto de aprendizagem; e de um conjunto de ferramentas que estabelecem um protótipo de ambiente para o desenvolvimento de objetos de aprendizagem (LODE Learning Object Development Environment) considerando o método LODM e o processo LODP. A abordagem LOD foi preliminarmente avaliada quanto à engenharia de objetos de aprendizagem multimídia e interativos, representados por apresentações multimídia e aplicações interativas para televisão digital para a plataforma Ginga do Sistema Brasileiro de Televisão Digital (SBTVD). Os resultados apontam para os benefícios da abordagem integrada para o desenvolvimento, com a geração de objetos de aprendizagem multimídias e interativos de forma mais ágil e sistemática, além de promover o reúso desde os primeiros passos da modelagem dos objetos de aprendizagem
Learning objects are an approach to address the increasingly complexity of computersupported education, fostering reuse and learning material quality. Such benefits can be improved by considering instructional design and the multimedia and interactivity features of current computing devices, providing a systematic method to develop learning objects. Considering such context, this thesis defines an approach to the development of multimedia and interactive learning objects, considering the digital television scenario. This approach is named LOD (Learning Object Development) and is composed of (1) a reference process (SPLOD Standard Process for Learning Object Development) from which we defined a process for learning objects development (LODP Learning Object Development Process) suitable for engineering of open educational resources; (2) a model-driven development method (LODM Learning Object Development Method) that integrates conceptual, instructional and interaction modeling of learning objects; and (3) a set of tools that establish a prototype for an environment for learning object development named LODE (Learning Object Development Environment). The LOD approach was evaluated with multimedia and interactive learning objects development realized as multimedia presentations and interactive digital television applications aimed at the Brazilian Digital Television System and its Ginga middleware. The results evince the benefits of the integrated approach, providing an agile and systematic development and fostering the reuse since the initial models of the learning object engineering process

Abstract:
Major Depressive Disorder is a devastating psychiatric illness with a complex genetic and environmental component that affects 10% of the UK population. Previous studies have shown that that individuals with depression show poorer performance on measures of cognitive domains such as memory, attention, language and executive functioning. A major risk factor for depression is a higher level of neuroticism, which has been shown to be associated with depression throughout life. Understanding cognitive performance in depression and neuroticism could lead to a better understanding of the aetiology of depression. The first aim of this thesis focused on assessing phenotypic and genetic differences in cognitive performance between healthy controls and depressed individuals and also between single episode and recurrent depression. A second aim was determining the capability of two decision-tree based methods to detect simulated gene-gene interactions. The third aim was to develop a novel statistical methodology for simultaneously analysing single SNP, additive and interacting genetic components associated with neuroticism using machine leaning. To assess the phenotypic and genetic differences in depression, 7,012 unrelated Generation Scotland participants (of which 1,042 were clinically diagnosed with depression) were analysed. Significant differences in cognitive performance were observed in two domains: processing speed and vocabulary. Individuals with recurrent depression showed lower processing speed scores compared to both controls and individuals with single episode depression. Higher vocabulary scores were observed in depressed individuals compared to controls and in individuals with recurrent depression compared to controls. These significant differences could not be tied to significant single locus associations. Derived polygenic scores using the large CHARGE processing speed GWAS explained up to 1% of variation in processing speed performance among individuals with single episode and recurrent depression. Two greedy non-parametric decision-tree based methods - C5.0 and logic regression - were applied to simulated gene-gene interaction data from Generation Scotland. Several gene-gene interactions were simulated under multiple scenarios (e.g. size, strength of association levels and the presence of a polygenic component) to assess the power and type I error. C5.0 was found to have an increased power with a conservative type I error using simulated data. C5.0 was applied to years of education as a proxy of educational attainment in 6,765 Generation Scotland participants. Multiple interacting loci were detected that were associated with years of education, some most notably located in genes known to be associated with reading and spelling (RCAN3) and neurodevelopmental traits (NPAS3). C5.0 was incorporated in a novel methodology called Machine-learning for Additive and Interaction Combined Analysis (MAICA). MAICA allows for a simultaneous analysis of single locus, polygenic components, and gene-gene interaction risk factors by means of a machine learning implementation. MAICA was applied on neuroticism scores in both Generation Scotland and UK Biobank. The MAICA model in Generation Scotland included 151 single loci and 11 gene-gene interaction sets, and explained ~6.5% of variation in neuroticism scores. Applying the same model to UK Biobank did not lead to a statistically significant prediction of neuroticism scores. The results presented in this thesis showed that individuals with depression performed significantly lower on the processing speed tests but higher on vocabulary test and that 1% of variation in processing speed can be explained by using a large processing speed GWAS. Evidence was provided that C5.0 had increased power and acceptable type I error rates versus logic regression when epistatic models exist - even with a strong underlying polygenic component, and that MAICA is an efficient tool to assess single locus, polygenic and epistatic components simultaneously. MAICA is open-source, and will provide a useful tool for other researchers of complex human traits who are interested in exploring the relative contributions of these different genomic architectures.

Abstract:
Background: There is growing evidence of abnormalities in neurocognition, neuroanatomy, and functional connectivity in posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). However, there has been less work on individuals who suffer with comorbid PTSD and MDD. It is important to investigate the neurobiology of this overlap because of its prevalence, its associated morbidity, and the hope that it may shed more light on the mechanisms involved in each disorder, including the role of the prefrontal regions. This dissertation tests the hypothesis that women with PTSD and MDD display distinct patterns of neurocognitive impairment and associated brain dysfunction, relative to healthy controls, and these effects will be amplified in patients with both disorders. Methods: This dissertation was undertaken within the Drakenstein Child Health Study, a study exploring child health determinants in mother-infant dyads from the Drakenstein district, Western Cape. Mothers (between 18 and 50 years) were recruited and divided into 4 groups: PTSD, MDD, PTSD with MDD, and healthy controls. Participants were assessed using the computerised NIH Toolbox, and paper and pencil neurocognitive tests. Domains assessed included memory, learning, and processing speed, and with particular focus on executive function and attention domains. Participants underwent resting-state functional imaging as well as structural brain imaging. Functional connectivity within and between cognitive control networks (salience network, dorsal attention network, and frontoparietal networks) and a default mode network were compared across the 4 groups. Neuroanatomical indices (cortical thickness, volume, and surface area) of 10 frontal cortical regions from the Desikan-Killiany atlas in Freesurfer 6 were analysed across the 4 groups. Results: All three clinical groups demonstrated no group differences on measures of attention and executive function, diagnoses of PTSD and MDD were associated with more intrusive thoughts and delayed recall impairment, respectively. However, neurocognitive findings indicate that PTSD with comorbid MDD is not associated with greater neurocognitive dysfunction relative to mono-diagnostic groups. Abnormal resting-state connectivity was observed for the MDD group in the default mode network, and for both comorbid and MDD patient groups within frontoparietal networks. Abnormal salience network connectivity for the comorbid group was observed when examining performance on the Pattern Comparison Processing Speed test. No between-network connectivity group differences were observed. Surface area and volume reductions of prefrontal regions were evident for PTSD and MDD, however, no volumetric and surface area differences were observed for the comorbid group. Conclusion: In this sample of mothers from a low-middle income region, distinct patterns of neurocognitive dysfunction and impairment in PTSD, MDD, and PTSD with MDD were observed. However, contrary to hypotheses, comorbidity is not associated with greater dysfunction and impairment and the associations of PTSD and comorbid MDD are not amplified in this sample. These findings have implications for the development of treatment plans for patients diagnosed with PTSD, MDD, and PTSD with comorbid MDD, so that interventions are tailored in a way that is responsive to differences between these groups in the presentation of neurocognitive profile, brain function, and structure.

Abstract:
No contexto das tecnologias propostas pela OMG, o MOF é utilizado para definir a sintaxe de linguagens de modelação, contudo, os aspectos semânticos não podem ser capturados usando esta linguagem. A descrição dos aspectos não sintácticos é realizada com recurso à linguagem OCL. Consequentemente, para uma completa definição de uma linguagem de modelação é necessário incorporar o OCL no MOF, criando uma infra-estrutura que possui a expressividade necessária para realizar esta função. Este projecto visa complementar a ferramenta de metamodelação MetaSketch Editor, introduzindo a capacidade de executar expressões em OCL e permitindo, desta forma, a verificação semântica dos modelos construídos usando o MetaSketch Editor. A gramática da linguagem OCL adoptada está de acordo com a especificação elaborada pela OMG (2006-05-01), juntando-se algumas contribuições de trabalhos existentes sobre esta linguagem. O projecto envolveu a implementação de um parser com recurso ao sistema GOLD Parser, a implementação da standard library do OCL em C# e, por último, a implementação de uma estratégia de execução das expressões em OCL.

Aspect-Oriented Software Development (AOSD) is a technique that complements the Object- Oriented Software Development (OOSD) modularizing several concepts that OOSD approaches do not modularize appropriately. However, the current state-of-the art on AOSD suffers with software evolution, mainly because aspect definition can stop to work correctly when base elements evolve. A promising approach to deal with that problem is the definition of model-based pointcuts, where pointcuts are defined based on a conceptual model. That strategy makes pointcut less prone to software evolution than model-base elements. Based on that strategy, this work defines a conceptual model at high abstraction level where we can specify software patterns and architectures that through Model Driven Development techniques they can be instantiated and composed in architecture description language that allows aspect modeling at architecture level. Our MDD approach allows propagate concepts in architecture level to another abstraction levels (design level, for example) through MDA transformation rules. Also, this work shows a plug-in implemented to Eclipse platform called AOADLwithCM. That plug-in was created to support our development process. The AOADLwithCM plug-in was used to describe a case study based on MobileMedia System. MobileMedia case study shows step-by-step how the Conceptual Model approach could minimize Pointcut Fragile Problems, due to software evolution. MobileMedia case study was used as input to analyses evolutions on software according to software metrics proposed by KHATCHADOURIAN, GREENWOOD and RASHID. Also, we analyze how evolution in base model could affect maintenance on aspectual model with and without Conceptual Model approaches
O Desenvolvimento de Software Orientado a Aspectos (DSOA) ? uma t?cnica que complementa o Desenvolvimento de Software Orientado a Objetos (DSOO) modularizando diversos conceitos que as abordagens para suporte ao DSOO n?o conseguiam modularizar adequadamente. No entanto, o estado da arte atual do DSOA sofre com a evolu??o de software, principalmente porque as defini??es de aspectos podem deixar de funcionar corretamente quando elementos do Modelo Base evoluem. Uma abordagem promissora para tratar este problema ? a defini??o de pontos de corte (pointcuts) baseados em modelos (model based-pointcuts), onde pontos de corte s?o definidos em termos de elementos de um Modelo Conceitual que s?o menos suscept?veis a evolu??o que elementos do Modelo Base.

Abstract:
Test Driven Development (TDD), Model-Driven Development (MDD), and Test Case Generation with their associated practices and tools each in their own right promise to deliver robust higher quality code more economically then other approaches. These process are not mutually exclusive but are not typically used together. This thesis develops a combined approach using complimentary aspects of each of the above three process. Test cases are described, generated, and then injected back into the model, which is then used to produce the test and production code. We have enhanced a model-driven tool to support the approach, adding a test case generator, capable of understanding augmented MDD software model and utilizing the constraints captured in our test-centric language to generate model-level test cases back into the model. Our results show that, with a reduction in overall effort one can produce a tested model-based system in which its test and implementation for multiple platforms such as C and Java, using one of multiple test xUnit frameworks.

Atualmente, é cada vez mais exigido como critério competitivo a aderência do processo de software de uma organização a um modelo ou norma de qualidade. Alcançar altos níveis de aderência é uma tarefa complexa para as organizações, pois a atividade de avaliar essa aderência exige cuidado ao ser realizada. Com isso, busca-se cada vez mais o apoio de ferramentas de avaliação computadorizadas, cujo objetivo é agilizar e tornar mais confiável o processo de avaliação dos processos de software. Ainda assim, um dos fatores que tendem a dificultar a utilização e propagação do uso de ferramentas é a atualização das normas de qualidade e dos métodos de avaliação associados, que visam se adequar constantemente às boas práticas do mercado. Ora, se uma ferramenta é criada baseada na norma de qualidade e no seu método de avaliação, qualquer mudança em algum dos dois componentes significa mudanças na ferramenta, gerando custos de manutenção e de distribuição da nova versão da ferramenta. Este trabalho busca criar uma engine de geração que seja sensível a esses mudanças, sem que seu processo de desenvolvimento necessite ser executado novamente. Para isto, utiliza o processo MDD (Model-Driven Development) para atender a esses requisitos, dado que o seu objetivo é transformar elementos mais abstratos em elementos mais concretos utilizando uma sucessão de transformações, através de modelos. O objetivo deste trabalho é, então, aplicar as regras de MDD aos modelos de qualidade e métodos de avaliação. Isto torna possível a criação de ferramentas para avaliação baseada nos modelos necessários à avaliação. Ou seja, através de um modelo de processo e de um metamodelo da norma de qualidade, além do método de avaliação, é possível criar de forma automática via MDD uma ferramenta que possa ser atualizada sob demanda, sem que seu código-fonte precise ser alterado manualmente.
Nowadays, it is increasingly required as a competitive criteria the adherence of an organization to a software model or quality standard process. Achieving high levels of adherence is a complex task for organizations, because the activity of evaluating this adherence requires care to be performed. Thus, it is increasing the nedd of computerized evaluation tools whose goal is to speed up and make more reliable the process of evaluating software processes.Still, one of the factors that tend to hamper the use and propagation of tool use is the change of the quality standards and assessment methods, which aim to adapt constantly to best practices in the market. So, if a tool is created based on quality standard and its evaluation method, any change in any of the two components mean changes in the tool, generating costs of maintaining and distributing the new version of the tool. This work seeks to develop a tool that is sensitive to that changes, but without the need of performing its development process again. For that, it uses MDD (Model- Driven Development) processes meet these requirements, since their goal is to transform more abstract elements into more concrete elements using a succession of transformations, through models. So, the goal of this work is to apply the rules of MDD to quality models and assessment methods. It makes possible to create tools based on models. In other words, through a process model and a metamodel quality standard, besides the evaluation method, it is possible to create automatically via MDD a tool that can be updated on demand, without its source code need to be changed manually.

Abstract:
Jordens resurser används åt att tillfredsställa människans livsstil vilket har lett till att jorden har börjat säga ifrån genom klimatförändring eftersom den inte klarar av det som människan gör. Hållbarhet är ett av de viktigaste ämnena i dagens samhälle och aldrig har det varit viktigare att tänka på miljön och hur man inte skadar den. Hållbarhet är ett ämne som det bedrivs mycket forskning kring, vilket företaget RISE lägger stora resurser på. De har tagit fram ett nytt material som baseras på träavfall, eftersom de vill undersöka ifall människan kan återanvända något som inte har ett värde och ge det ett nytt värde och nytt liv. I ett samarbete med RISE har jag undersökt detta material som kallas för White Wood och fått i uppdrag att hitta ett användningsområde för materialet baserat på dess egenskaper. Forskningen kring White Wood har inte ännu kommit till stadiet där det kan börja produceras i stor skala, då det krävs en hel del fortsatta studier innan det steget kan tas. Målet med min studie har varit att hitta ett lämpligt användningsområde för White Wood när det är redo att ta det steget. Jag har använt mig av Material Driven Design metoden då detta är ett materialdrivet arbete som utgår ifrån materialets egenskaper och möjligheter. Jag har haft ett öppet sinne och låtit materialet och utforskandet av detta ta mig framåt, men mina tidigare erfarenheter och kunskaper har också varit till stor nytta. Genom att utmana och testa gränserna för White Wood så har jag upptäckt unika egenskaper och tillverkningsmetoder. Denna summering använde jag mig av för att sedan kunna placera White Wood inom elektronikområdet och ge konkreta produktförslag. Jag hoppas att mitt bidrag inom denna forskning kommer till nytta och kan inspirera till ökad hållbarhet nu och för framtiden.

Abstract:
Vi behöver minska vår materialkonsumtion, idag gör vi av med mer resurser än vad vi har tillgång till. I den här studien har först en materialkonstruktion tagits fram och därefter ett produktkoncept för konstruktionen. För att ta fram materialkonstruktionen har biomimicry använts. Biomimicry är designmetoder för att lösa designproblem med inspiration från naturen. Naturen använder sig av så lite material som möjligt. Materialkonstruktionen är inspirerad av växtceller. Konstruktionen har två hierarkier som går i två olika riktningar, en riktning som går längs med och en riktning som går i djupled.För att hitta ett produktkoncept för materialkonstruktionen har material driven design (MDD) använts. MDD är en experimentell metod för att lära känna ett material och förstå dess användningsområde. Produktkonceptet är en stapelbar pall.För att minska på resurser används 3d-printning. 3d-printning är en additiv teknik och minskar på så sätt materialåtgång. Dessutom kan allt material lätt återanvändas eftersom det bara behövs ett material.Produkten kan produceras lokalt vilket minskar på transporter. PLA har använts som material i den här studien.
We need to reduce our material consumption, today we are wasting more resources than we have access to. In this study, a material construction was first developed and then a product concept for the construction. Biomimicry has been used to develop the material construction. Biomimicry are design methods for solving design problems with inspiration from nature. Nature uses as little material as possible. The material construction is inspired by plant cells. The construction has two hierarchies that go in two different directions.To find a product concept for the construction, material driven design (MDD) has been used. MDD is an experimental method used to get to know a material and understand its application. The product concept is a stackable pallet.To reduce resources, 3D printing is used. 3D printing is an additive technology and thus reduces material consumption. In addition, all material can be easily reused as only one material is needed.The product can be produced locally, which reduces on transport. PLA has been used as material in this study.

Abstract:
La question de l’assortiment des produits dans les magasins est devenue un enjeu stratégique majeur pour pénétrer les nouveaux marchés et fidéliser les clients. La forte progression des marques de distributeur (MDD) face aux marques nationales (MN) et l’internationalisation croissante des enseignes de distribution sont deux bouleversements qui ont particulièrement retenu l’attention des chercheurs et des praticiens ces dernières années.Dans ce contexte, la problématique centrale de cette thèse est de comprendre les facteurs explicatifs du comportement d’achat envers les produits MDD. Dans le cadre d’une posture épistémologique hypothético-déductive, nous adoptons une approche psycho-cognitive tout en prenant en compte les travaux issus de l’achat impulsif. Dans ce sens, une revue des travaux antérieurs combinée à une étude qualitative exploratoire multi-méthodes (étude documentaire, entretiens avec 24 consommateurs et entretiens 8 managers) a été effectuée au Brésil. Nous avons par la suite conçu un modèle conceptuel intégrateur des déterminants du choix de la MDD, formulé des hypothèses de recherche et effectué les tests de validation avec un échantillon de 600 consommateurs brésiliens. Les résultats ont permis de valider une nouvelle échelle de mesure bidimensionnelle de l’image prix perçue des MDD. Ils montrent aussi que les facteurs explicatifs du choix de la MDD sont multiples et de nature diverse (perception de la valeur des MDD, attitude générale envers les MDD, perception de l’image du magasin, image prix perçue des MDD, familiarité avec le magasin, etc.). Ils indiquent également que l’importance des relations structurelles du modèle varie en fonction du caractère international ou local de l’enseigne.La discussion des résultats aboutit à la formulation de recommandations managériales (variables qui affectent le plus le comportement d’achat envers les MDD des enseignes étudiées et la perception de l’image du magasin) et méthodologiques (orthogonalisation pour tester la modération des variables latentes de second ordre). La conclusion synthétise les apports, limites et voies de recherche futures
The question of product and brand assortment within the stores has become a major strategic challenge to penetrate new markets and retain customers. Two changes that have particularly caught the attention of researchers and practitioners are the strong growth of store brands (SBs) compared to national brands (NB) and the increasing internationalization of retail chains.In this context, the central issue of this thesis is to understand factors explaining purchase behavior toward SB products. In this sense, a review of previous work combined with a qualitative multi-method study (desk research, interviews with 24 consumers and 8 managers) was conducted in Brazil. We then developed an integrated conceptual model of the determinants of SB choice, proposed research hypotheses and performed the validation tests with a sample of 600 Brazilian consumers.The results allow us to validate a new two-dimensional scale of SB perceived price-image. They also show that factors explaining SB choice are numerous and diverse in nature (SB perceived value, general attitude towards SBs, store image perceptions, perceived SB price-image, etc.). They also indicate that the importance of the structural paths in the model depends on the retailer as local or international.The discussion of the results leads to managerial recommendations (variables that most affect purchase behavior toward SBs and store image perceptions) and methodological ones (orthogonalization to test the moderation of second order latent variables). The conclusion summarizes the contributions, limitations and future research avenues

Abstract:
Unternehmen agieren heute in einer hochdynamischen Umwelt, wodurch die Anforderungen an Business Intelligence-Systeme (BI-Systeme) sich stetig verändern. Durch zügiges Reagieren darauf können sich Unternehmen Wettbewerbsvorteile verschaffen. Die dazu notwendige Wandlungsfähigkeit von BI-Systemen setzt voraus, dass bereits die BI-Architektur auf Flexibilität ausgelegt ist. Die Anwendung des Paradigmas der modellgetriebenen Softwareentwicklung auf die Domäne des Data Warehouse Engineerings (DWE) kommt diesem Bedarf nach. Zudem muss neben der Agilität von BI-Systemen auch der Faktor der Korrektheitsprüfung nach vorgenommenen Änderungen betrachtet werden. Es soll untersucht werden, inwieweit sich die im modellgetriebenen DWE anfallenden Metadaten zur Unterstützung und Automatisierung von Softwaretests zur Korrektheitsprüfung nutzen lassen. Die so erzielte Verringerung des Überprüfungsaufwandes führt zu einer verbesserten Wandlungsfähigkeit von BI-Architekturen und kommt somit dem Bedarf von effizienten agilen BI-Lösungen nach.

Aspect Oriented approaches associated to different activities of the software development process are, in general, independent and their models and artifacts are not aligned and inserted in a coherent process. In the model driven development, the various models and the correspondence between them are rigorously specified. With the integration of aspect oriented software development (DSOA) and model driven development (MDD) it is possible to automatically propagate models from one activity to another, avoiding the loss of information and important decisions established in each activity. This work presents MARISA-MDD, a strategy based on models that integrate aspect-oriented requirements, architecture and detailed design, using the languages AOV-graph, AspectualACME and aSideML, respectively. MARISA-MDD defines, for each activity, representative models (and corresponding metamodels) and a number of transformations between the models of each language. These transformations have been specified and implemented in ATL (Atlas Definition Language), in the Eclipse environment. MARISA-MDD allows the automatic propagation between AOV-graph, AspectualACME, and aSideML models. To validate the proposed approach two case studies, the Health Watcher and the Mobile Media have been used in the MARISA-MDD environment for the automatic generation of AspectualACME and aSideML models, from the AOV-graph model

The approach Software Product Line (SPL) has become very promising these days, since it allows the production of customized systems on large scale through product families. For the modeling of these families the Features Model is being widely used, however, it is a model that has low level of detail and not may be sufficient to guide the development team of LPS. Thus, it is recommended add the Features Model to other models representing the system from other perspectives. The goals model PL-AOVgraph can assume this role complementary to the Features Model, since it has a to context oriented language of LPS's, which allows the requirements modeling in detail and identification of crosscutting concerns that may arise as result of variability. In order to insert PL-AOVgraph in development of LPS's, this paper proposes a bi-directional mapping between PL-AOVgraph and Features Model, which will be automated by tool ReqSys-MDD. This tool uses the approach of Model-Driven Development (MDD), which allows the construction of systems from high level models through successive transformations. This enables the integration of ReqSys-MDD with other tools MDD that use their output models as input to other transformations. So it is possible keep consistency among the models involved, avoiding loss of informations on transitions between stages of development

Dessa forma, ? recomend?vel agregar o Modelo de Features a outros modelos que representem o sistema sob outras perspectivas. O Modelo de Metas PL-AOVgraph pode assumir esta fun??o complementar ao Modelo de Features, uma vez que possui uma linguagem voltada para o contexto das LPS s, que permite a modelagem de requisitos de forma detalhada e a identifica??o de caracter?sticas transversais, que podem surgir em decorr?ncia da variabilidade. Com o objetivo de inserir PL-AOVgraph no processo de desenvolvimento das LPS s, este trabalho prop?e um mapeamento bi-direcional entre PLAOVgraph e Modelo de Features, que ser? automatizado pela ferramenta ReqSys-MDD. Esta ferramenta utiliza a abordagem de Desenvolvimento Orientado a Modelos (Model-Driven Development MDD), que permite a constru??o de sistemas a partir de modelos de alto n?vel, atrav?s de transforma??es sucessivas. Isto possibilita a integra??o de ReqSys-MDD com outras ferramentas MDD que utilizem seus modelos de sa?da como entrada para outras transforma??es.

Abstract:
Syftet med detta projekt är att med hjälp av en materialinriktad designprocess skapa en produkt av biokompositmaterialet OrganoComp® för att demonstrera dess styrkor och möjligheter. Arbetet kommer att följa metoden ”Material Driven Design (MDD)”, vilket betyder att processen kommer att börja med en noggrann studie av materialet – dels tekniskt och ur ett användarcentrerat perspektiv, men även jämförelsemässigt mot andra material. Insikterna från dessa studier kommer sedan trattas ner och sammanfattas i en ”designintention” som ska sätta målet för designarbetet. Slutligen kommer ett antal koncept som uppfyller designintentionen arbetas fram, varav ett koncept – ett litet, ihopvikbart och nedbrytbart paraply/regnskydd kommer att väljas ut som det slutgiltiga. Paraplyet visar på materialets vattenavvisande egenskaper, i kombination med hårdhet och vikbarhet.  Målet med projektet är att skapa en demonstrator som även har potential att bli en användbar produkt i framtiden, och samtidigt ge företaget OrganoClick nya insikter och flera förslag på nya användningsområden för sitt material.

Abstract:
Actualmente, uno de los principales retos de la Ingeniería del Software (IS) es el desarrollo de sistemas de calidad. La calidad es una propiedad del software que cuenta con diversas características, entre ellas la usabilidad, que es en la que se centra esta tesis. La IS se ha centrado históricamente en problemas de funcionalidad y de persistencia, relegando a un segundo plano aspectos de la interacción con el usuario, y más concretamente, de la usabilidad. Este vacío ha sido cubierto por la comunidad Interacción Persona-Ordenador (IPO), que ha propuesto recomendaciones para mejorar la usabilidad. Algunas de estas recomendaciones deben ser consideradas desde las primeras fases de construcción de los sistemas a fin de evitar realizar cambios en la arquitectura una vez ésta haya sido diseñada. Estas recomendaciones se conocen como Functional Usability Features (FUF). La incorporación de los FUFs desde las primeras fases del proceso de desarrollo añade cierta complejidad a la construcción de sistemas, ya que el analista ha de tener en cuenta más factores a la hora del desarrollo. Esta tesis presenta una solución basada en transformaciones entre modelos. El objetivo de la tesis es el de presentar un método (llamado MIMAT) para incorporar los FUFs dentro de un método de desarrollo Model-Driven Development (MDD). Para ello, se profundiza en los cambios que el diseñador del método MDD debe aplicar para enriquecer dicho método con los FUFs. Una vez incorporados los FUFs, el analista que modele sistemas con el método MDD puede utilizar las características de usabilidad en el desarrollo de sistemas. La principal ventaja de esta aproximación es que el analista puede incorporar las características de usabilidad simplemente a partir de modelos conceptuales, dejando la implementación a las transformaciones de modelo a código. La factibilidad de MIMAT se ha demostrado aplicándolo a un método de desarrollo MDD específico: OO-Method.

Abstract:
Regelverket för medicintekniska produkter är omfattande och medicintekniska företag lägger idag stora resurser på att säkerställa att deras produkter uppfyller de lagar och krav som finns. Detta arbete beskriver författarnas bidrag till CE-märkningsprocessen på det nystartade företaget LARA Diagnostics första produkt, en handhållen enhet för utvärdering av perifer neuropati samt hur processen att CE-märka en medicinteknisk produkt generellt går till för ett mindre eller nystartat företag. Arbetet syftar till att visa vilka utmaningar mindre bolag har i synnerhet vid processen att CE-märka sin första produkt samt vad företag kan göra för att effektivisera sin process. I arbetet visas att mindre företag kan effektivisera sin process genom att: Tidigt lägga grunden till CE-märkningen. Se till att rätt kompetens finns eller införskaffas utifrån Redan i produktutvecklingen säkerställa att väsentliga krav uppfylls, gärna genom att följa harmoniserade standarder. Arbetet visar även att kraven inom det regulatoriska området för medicintekniska produkter blir hårdare med tiden och att den utvecklingen förväntas fortsätta.
The regulatory framework for medical devices is extensive and the medical device industry spends considerable resources on ensuring that their products comply with existing laws and requirements. This paper describes the authors’ contribution to the CE marking process of the very first product from the startup company LARA Diagnostics, a handheld device for the evaluation of peripheral neuropathy, as well as how the process of CE marking a medical device is carried out in general for a small or startup business. The work aims to point out the challenges for smaller companies in particular to get their first product certified, but also what can be done to streamline that process. The paper shows that small companies can improve the process by: Laying the foundation for CE marking early in the process. Ensure that the right skills exist internally or are acquired externally. Making sure that essential requirements are met early in the product development life cycle, preferably by adhering to harmonized standards. The paper also shows that the requirements within the regulatory framework for medical devices are becoming stricter over time and that this trend is expected to continue.

Abstract:
A abordagem de desenvolvimento dirigido por modelos (DDM) propõe que modelos (e transformações entre modelos) assumam o papel principal no desenvolvimento de sistemas. Entretanto, não há uma notação consensual para modelagem de persistência baseada em arcabouços de mapeamento objeto-relacional: enquanto a UML não possui recursos específicos para a modelagem de persistência, o modelo entidade-relacionamento não expressa os conceitos dinâmicos existentes na UML. Este trabalho propõe o perfil UML MD-JPA (Model Driven JPA) para a modelagem de persistência baseada na já difundida API de persistência Java (JPA), buscando a modelagem dos elementos persistentes e transientes de forma mais coerente e integrada. São especificadas as principais características do perfil MD-JPA, assim como a maneira pela qual modelos que adotam este perfil podem ser transformados em implementação Java, através de transformações de modelos propostas em uma abordagem DDM. Por fim, uma ferramenta de código livre foi desenvolvida para disponibilizar para comunidade os resultados deste trabalho.
The model driven development (MDD) approach proposes that models (and modelto- model transformations) play the main role on system development. However, there is not a consensual notation to model persistence based upon object relational mapping frameworks: while UML lacks specific resources for persistence modeling, the entityrelationship model does not make reference to the dynamic concepts existing in UML. This work proposes MD-JPA, a UML profile for persistence modeling based on the well-known Java Persistence API (JPA), pursuing the modeling of transient and persistent elements in a more coherent and integrated way. This work describes the main characteristics of MD-JPA as well as the way that models that adopt such profile can them be used to generate a Java implementation by the application of the proposed model transformations on a MDD approach. Finally, an open source tool was developed to make the results of this work available to the community.

Abstract:
Major depressive disorder (MDD) is a relevant condition to consider regarding Work Capacity Evaluation (WCE) because of its high prevalence, strong impact on short-term work disability, and low rate of treatment. The challenge that faces occupational therapists (OTs) is that there is no specific guideline and process to follow when conducting Work Capacity Evaluation with clients suffering from MDD. The researcher had also noted conflicting opinions with regard to the outcome of Work Capacity Evaluation (WCE) and recommendations in occupational therapy reports. The researcher is of the opinion that indeed occupational therapy assessments need to be clear about what to measure, and selection of appropriate standardised measures and non-standardised assessments is needed. Therefore, the research question was, what are the perceptions and practices of occupational therapists in determining work capacity of employees suffering from major depressive disorder? The aim of this study was to describe the perceptions and practices of occupational therapists in determining work capacity of employees suffering from major depressive disorder. The literature showed that Work Capacity Evaluation assists to determine the employee’s returnto- work. The Code of Good Practice: Dismissal contained in the Labour Relations Act of 1998, stipulates that incapacity on the ground of ill health or injury may be either temporary or permanent. The nature of this study was a mixed method design including both qualitative and quantitative approaches. The phenomenological strategy was used. The study had a sample size of 68 participants, practising as occupational therapists. Purposive sampling was used. The data were collected in four distinct phases, referred to as sequential exploratory strategy with elements of embedded design. Phase one, used descriptive open-ended questions; phase two was a close-ended questionnaire to confirm findings in phase one; phase three consisted of focus group interviews and phase four was member checking to confirm findings in phase three. During data analysis, five themes related to employees suffering from MDD emerged and they were identified as: (1) the content of comprehensive assessment for work capacity evaluation, (2) the process of work capacity evaluation, (3) the competency requirements of the occupational therapist, (4) occupational performance and (5) formulating return-to-work decision. Recommendations related to the five themes were formulated and suggestions for future research proffered. The study clarified and confirmed that occupational therapists have a major role to play in performing work capacity of employees suffering from major depressive disorder, and that they need to be competent in performing these evaluations.

Abstract:
Ubiquitous and Pervasive computing put forth a vision where environments are enriched with devices that provide users with services to serve them in their everyday lives. The building of such environments has the final objective of automating tedious routine tasks that users must perform every day. This automation is a very desirable challenge because it can considerably reduce resource consumption and improve users' quality of life by 1) making users' lives more comfortable, eficient, and productive, and 2) helping them to stop worrying and wasting time in performing tasks that need to be done and that they do not enjoy. However, the automation of user tasks is a complicated and delicate matter because it may bother users, interfere in their goals, or even be dangerous. To avoid this, tasks must be automated in a non-intrusive way by attending to users' desires and demands. This is the main goal of this thesis, that is, to automate the routine tasks that users want the way they want them. To achieve this, we propose two models of a high level of abstraction to specify the routines to be automated. These models provide abstract concepts that facilitate the participation of end-users in the model specification. In addition, these models are designed to be machine-processable and precise-enough to be executable models. Thus, we provide a software infrastructure that is capable of automating the specified routines by directly interpreting the models at runtime. Therefore, the routines to be automated are only represented in the models. This makes the models the primary means to understand, interact with, and modify the automated routines. This considerably facilitates the evolution of the routines over time to adapt them to changes in user behaviour. Without this adaptation, the automation of the routines may not only become useless for end-users but may also become a burden on them instead of being a help in their daily life.

Abstract:
Introduction: As modern diseases such as depression and obesity become more prevalent, the need for investigations into the role of lifestyle factors in their development becomes more pressing. Studies have associated both stress and obesity with depression, however there are currently few studies that explore the role of combined subclinical stress and an obesogenic Western diet (WD) in the aetiology of depression. Subclinical stress refers to the stress as experienced by people in their everyday life due to work, family, or outside worldly events. Aims and hypothesis: The primary aim of this study was to assess whether subclinical stress and an obesogenic diet interact to promote metabolic disease and mood disorders such as MDD. A secondary aim of the study was to assess potential hormonal and neuronal changes induced by stress and the obesogenic WD and relate these to mood disorders. We hypothesised that chronic stress and a WD will act synergistically to promote metabolic disease and mood disorders. Methods: Sixty-four C57BL6/J mice randomly divided into 4 groups (n=16) Control (C), Western Diet (WD), control diet + restraint stress (C+RS), and WD+RS. WD macronutrient content was: 32% fat, 57% carbohydrate, 11% protein and 14% fat, 59% carbohydrate, 19% protein for the control diet. Two-hour restraint per day was used to induce restraint stress (RS) for the last two weeks of the 16-week feeding program used in the study. Body weight was assessed weekly and blood was collected after habituation and before sacrifice. Behavioural data was obtained using an open field test and sucrose preference test. Brain tissue and blood samples were collected after animal sacrifice. ELISAs were performed on regions of the brain thought to be impacted by depression and diabetes, specifically frontal cortex and hippocampus. ELISAs that were performed on the brain tissue included: norepinephrine, epinephrine, glutamate, dopamine, serotonin, −aminobutyric acid (GABA), cholesterol, and melatonin. Results: WD animals consumed more food in both absolute weight (P<0.0001) and in calorie content (P<0.0001), however the only significant difference in final body weight at sacrifice was between WD + stress and control diet + stress animals (P<0.05). No significant differences were found in post intervention (after 15 weeks feeding and 2 weeks restraint) glucose, triglycerides, or cholesterol. Fasting insulin (between stress groups: P<0.05, between non stressed groups: P<0.001) and HOMA-IR values were however significantly higher in WD animals (C+RS vs. WD+RS groups: P<0.01, and, C vs. WD groups P<0.001). Wall seeking behaviour in open field test (OFT) suggests heightened anxiety in animals exposed to stress while animals not exposed to stress displayed a reduction in locomotion post-intervention compared to pre-intervention OFT (P<0.01). WD animals also displayed features of anhedonia with the sucrose preference test (SPT) (P<0.001). The WD increased hippocampal leptin (P<0.05), and decreased hippocampal dopamine (P<0.05) and noradrenaline (P<0.01). Stress reduced frontal cortex BDNF (P<0.05) and increased frontal cortex glutamate (P<0.05). Combined stress and the western diet reduced levels of hippocampal BDNF (P<0.05) and tryptophan (P<0.05) and reduced frontal cortex levels of leptin (P<0.05). Conclusion: The WD successfully induced a prediabetic state due to a combination of hyperphagia and an increased caloric intake. Metabolic state was changed by Western diet to a pre-diabetic state, with increased insulin and HOMA-IR in the absence of elevated fasting glucose, triglycerides, or cholesterol. The WD also caused anhedonia which was associated with changes in hippocampal dopamine, leptin, and noradrenaline levels. Our data supports the additive effects of WD + subclinical stress on neural levels of BDNF, tryptophan, and leptin all of which are relevant to mood and metabolic disorders. A model of low-grade stress alone produced behavioural changes consistent with increased anxiety and modified BDNF and glutamate levels. Stress induced changes distinctly targeted the frontal cortex whereas all changes attributed to the WD occurred in the hippocampus.

Abstract:
A travers le cas des fournisseurs de Marques de Distributeurs (MDD) en agro-alimentaire, cette thèse vise à montrer que la satisfaction du fournisseur peut être expliquée par la proximité entre ce dernier et son distributeur. En adoptant une posture épistémologique positiviste et une démarche hypothético-déductive, nous avons réalisé une revue de littérature qui a permis d’élaborer un modèle conceptuel. Celui-ci postule que la proximité, déclinée en quatre dimensions-proximité relationnelle, proximité identitaire, proximité de processus et proximité géographique, est un antécédent de la confiance et in fine de la satisfaction de cette relation B to B. Afin de tester les hypothèses formulées, nous avons ensuite mené une étude empirique auprès de 93 fournisseurs de MDD de la Grande Distribution Alimentaire. Une première phase de collecte des données s’est déroulée au salon MDDEXPO en avril 2014 et a permis de recueillir 51 questionnaires. La deuxième phase de collecte a été réalisée via le réseau social numérique professionnel VIADEO et a permis de recueillir 42 réponses. Puis, nous avons soumis notre modèle au test avec la méthode PLS sous le logiciel SMARTPLS3. Les résultats de cette recherche montrent que deux dimensions de la proximité permettent d’accroitre directement la satisfaction du fournisseur de MDD de la relation, sans « passer par la confiance du fournisseur de MDD envers son distributeur »
Through the case of private label supplier in food sector, this thesis aims to show that the satisfaction of private label supplier can be explained by the proximity with his distributor. By adopting a positivist epistemological position and hypothetical-deductive approach, we conducted a literature review that allowed us to develop an integrative model made up of four dimensions: relational proximity, identity proximity, process proximity and geographical proximity. Then realized an empirical study alongside 93 suppliers of private label. A first data collection stage took place in MDDEXPO on April 2014 and has enabled to collect 51 questionnaires. The second phase of collection was done via VIADEO and which came up with 42 responses. Further, we submitted our model to test using PLS method under SMARTPLS3 software. The results of this research show that two dimensions of proximity have direct relationship with increasing private label supplier satisfaction. They are, in the order of importance of structural relations, level of cooperation (relational proximity) and adaptations (process proximity). They also indicate that three dimensions of proximity are used to increase the satisfaction of private label supplier. They are , in order of importance of structural relationships, identity proximity (shared values), social bonds (sub-scale relational proximity) and geographic proximity. Moreover, they show that two sub-dimensions of proximity do not significantly influence the confidence nor the satisfaction of private label supplier to its retailer. It is a question of information exchange (relational proximity) and idiosyncratic assets (process proximity)

Abstract:
Certain electrophysiological markers hold promise in distinguishing individuals with major depressive disorder (MDD) and in predicting antidepressant response, thereby assisting with assessment and optimizing treatment, respectively. This thesis examined resting brain activity via electroencephalographic (EEG) recordings, as well as EEG-derived event-related potentials (ERPs) to auditory stimuli and facial expression presentations in individuals with MDD and controls. Additionally, the utility of resting EEG as well as auditory ERPs (AEPs), and the associated loudness-dependence of AEPs (LDAEP) slope, were assessed in predicating outcome to chronic treatment with one of three antidepressant regimens [escitalopram (ESC); bupropion (BUP); ESC+BUP]. Relative to controls, depressed adults had lower pretreatment cortical activity in regions implicated in approach motives/positive processing. Increased anterior cingulate cortex (ACC)-localized theta was observed, possibly reflecting emotion/cognitive regulation disturbances in the disorder. AEPs and LDAEPs, putative indices of serotonin activity (implicated in MDD etiology), were largely unaltered in MDD. Assessment of ERPs to facial expression processing indicated slightly blunted late preconscious perceptual processing of expressions, and prolonged processing of intensely sad faces in MDD. Faces were rated as sadder overall in MDD, indicating a negative processing bias. Treatment responders (vs. non-responders) exhibited baseline cortical hypoactivity; after a week of treatment, cortical arousal emerged in responders. Increased baseline left fronto-cortical activity and early shifts towards this profile were noted in responders (vs. non-responders). Responders exhibited a steep, and non-responders shallow, baseline N1 LDAEP derived from primary auditory cortex activity. P2 LDAEP slopes (primary auditory cortex-derived) increased after a week of treatment in responders and decreased in non-responders. Consistent with overall findings, ESC responders displayed baseline cortical hypoactivity and steep LDAEP-sLORETA slopes (vs. non-responders). BUP responders also exhibited steep baseline slopes and high ACC theta. These results indicate that specific resting brain activity profiles appear to distinguish depressed from non-depressed individuals. Subtle ERP modulations to simple auditory and emotive processing also existed in MDD. Resting alpha power, ACC theta activity and LDAEP slopes predicted antidepressant response in general, but were limited in predicting outcome to a particular treatment, which may be associated with limited sample sizes.

Abstract:
The use of models for designing and developing Information Systems (IS) has changed in recent years. Models are no longer considered a peripheral documentation medium that is poorly maintained and often neglected. Rather, models are increasingly seen as essential parts of the final product—as central artifacts that drive and guide the development efforts. The knowledge that modelers rely on when designing models is represented as formal models and clearly defined rules for transforming the models. The flexibility, reliability, and effectiveness offered by the formal models and the transformations are making Model Driven Development (MDD) a popular choice for building IS. Models also serve in describing enterprise design, where enterprise-level models capture organizational knowledge and aid in understanding, improving, and growing the enterprise. Enterprise Modeling (EM) offers a structured and unified view of the enterprise, thereby enabling more informed and accurate decisions to be made. Many MDD approaches have been proposed to tackle a wide range of IS-related issues, but little attention is being paid to the source of the knowledge captured by the IS models. EM approaches capture organizational knowledge and provide the necessary input and underlying context for designing IS. However, the results produced by EM approaches need to be manually analyzed by modelers to create the initial MDD model. This interruption of the MDD process represents a gap between enterprise models and MDD models. Limited research has been done to connect EM to MDD in a systematic and structured manner based on the principles of model-driven development. This thesis proposes a unifying meta-model for integrating EM and MDD. The meta-model captures the inherent links that exist between organizational knowledge and IS design. This helps to improve the alignment between organizational goals and the IS that are created to support them. The research presented herein follows the guidelines of the design science research methodology. It starts with a state-of-the-art survey of the current relationship between MDD and prior stages of development. The findings of the survey are used to elicit a set of necessary properties for integrating EM and MDD. The unifying meta-model is then proposed as the basis for an integrated IS development approach that applies the principles of MDD and starts on the enterprise level by considering enterprise models in the development process. The design of the meta-model supports the elicited integration properties. The unifying meta-model is based on the Enterprise Knowledge Development (EKD) approach to EM. A prototype tool is developed to support the unifying meta-model, following a study to choose a suitable implementation environment. The use of the unifying meta-model is demonstrated through the implemented tool platform using an example case study, revealing its advantages and highlighting the potential for improvement and future development.

Thesis, Örebro universitet, Institutionen för medicinska vetenskaper, 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:oru:diva-73977.

Abstract:
Background: Psychiatric diseases such as bipolar disorder, major depressive disorder (MDD)and schizophrenia are chronic ailments that severely affect daily function and quality of life. A relationship between elevated levels of proinflammatory cytokines and these disorders hasbeen suggested in several studies. Lithium is used as a treatment in bipolar disorder, and as anadjunctive treatment in MDD and schizophrenia. Despite the extensive use of lithium, it’smechanism of action is not fully understood. One of the proposed hypotheses of lithium’smechanism of action is reduction in the levels of proinflammatory cytokines. Aim: The aim of this systematic literature review is to describe the effects of lithium onproinflammatory cytokines (IL-1, IL-6, INF- γ, TNF) in bipolar disorder, MDD andschizophrenia. Methods: The study was conducted through a search in the electronic database PubMed.Using the PICOS format, inclusion and exclusion criteria were specified. Search words andfilters were combined using both Medical Subject Headings (MeSH) terms and free textsearch words. The search initially resulted in 105 articles and through inclusion and exclusioncriteria full-text articles were estimated for eligibility. Risk of bias was estimated using theCochrane Handbook. Results: A total of 10 eligible articlets were included in this study. Nine out of 10 articlesinvestigated bipolar patients, and one article investigated patients with MDD. No article investigated patients with schizophrenia. Four out of 9 articles regarding bipolar patientsreported a significant decrease in some proinflammatory cytokines after lithiumtreatment, 4 articles reported a significant increase, and one article reported no change in theproinflammatory cytokines. In two well conducted studies where bipolar disorder wasinvestigated, lithium had differential effects, namely decreasing proinflammatory cytokines inlithium responders compared to lithium non-responders. No significant change inproinflammatory cytokine levels after lithium treatment were found in the article studyingMDD patients. Conclusions: The results indicated that lithium may have different effects depending onwhich specific cytokine was studied and on the specific characteristics of the studiedpopulation. Therefore, the outcomes of our review cannot unequivocally answer whetherlithium acts by increasing or decreasing proinflammatory cytokines, or both depending on theexperimental conditions. Further research is needed to fully elucidate the relationship betweenlithium and proinflammatory cytokines in bipolar disorder, MDD and schizophrenia.

Abstract:
The following document proposes a traceability solution for model-driven development. There as been already previous work done in this area, but so far there has not been yet any standardized way for exchanging traceability information, thus the goal of this project developed and documented here is not to automatize the traceability process but to provide an approach to achieve traceability that follows OMG standards, making traceability information exchangeable between tools that follow the same standards. As such, we propose a traceability meta-model as an extension of MetaObject Facility (MOF)1. Using MetaSketch2 modeling language workbench, we present a modeling language for traceability information. This traceability information then can be used for tool cooperation. Using Meta.Tracer (our tool developed for this thesis), we enable the users to establish traceability relationships between different traceability elements and offer a visualization for the traceability information. We then demonstrate the benefits of using a traceability tool on a software development life cycle using a case study. We finalize by commenting on the work developed.

Typically Web services contain only syntactic information that describes their interfaces. Due to the lack of semantic descriptions of the Web services, service composition becomes a difficult task. To solve this problem, Web services can exploit the use of ontologies for the semantic definition of service s interface, thus facilitating the automation of discovering, publication, mediation, invocation, and composition of services. However, ontology languages, such as OWL-S, have constructs that are not easy to understand, even for Web developers, and the existing tools that support their use contains many details that make them difficult to manipulate. This paper presents a MDD tool called AutoWebS (Automatic Generation of Semantic Web Services) to develop OWL-S semantic Web services. AutoWebS uses an approach based on UML profiles and model transformations for automatic generation of Web services and their semantic description. AutoWebS offers an environment that provides many features required to model, implement, compile, and deploy semantic Web services

Abstract:
In this study, the Turkish left in the 1960s is discussed in the light of the term peculiarism. This is done on the basis of three groups of the Turkish left in the period, namely the Yö
n journal, the MDD group and the TiP with specific reference to Mehmet Ali Aybar. The main premises of the term peculiarism are considered to be nationalism, Kemalism, developmentalism or non-capitalist path of development, the idea of a &ldquo
popular national front&rdquo
and anti-imperialism. Accordingly, each group is discussed on the basis of the above told concepts.

Abstract:
Dans un circuit asynchrone, la synchronisation entre les blocs est locale: on s'affranchit ainsi des contraintes liées à l'horloge. Ces circuits sont plus robustes, modulaires, moins bruités, et ont une consommation dynamique plus faible que les circuits synchrones. Cependant, le manque d'outils de conception de tels circuits freine leur développement. Cette thèse a permi de développer une technique de synthèse automatique de circuits asynchrones quasi insensibles aux délais (QDI), qui sont particulièrement robustes. La méthode de synthèse permet de synthétiser un circuit totalement décomposé en portes logiques élémentaires, ce qui permet d'effectuer une projection technologique. De plus, une étude formelle réalisée durant la thèse démontre que les circuits synthétisés respectent la contrainte de quasi insensibilité aux délais. Cette technique de synthèse a été développé au sein du projet TAST. Elle a été validée sur un ensemble de circuits de tests
In an asynchronous circuit, the synchronization between the blocs is local: the constraints due to the clock do not apply. These circuits are more robust, modular, have less noise and a lower dynamic power consumption that asynchronous circuits. However, the lack of design tools for such circuits prevents them from spreading widely. This thesis aimed at developping an automatic synthesis technique targeting asynchronous quasi delay insensitive (QDI) circuits, which are particularly robust. The technique synthesizes a circuit totally decomposed in elemetary logical gates, which allows a later technology mapping. Moreover, a formal study done during this thesis proves that the circuits synthesized respect the constraint of quasi delay insensitivity. This synthesis technique was developped in the TAST project. Is has been validated on a set of test circuits
