Variability Management in Dynamic Software Product Lines: A Systematic Mapping

Dynamic Software Product Lines (DSPLs) are SPLs in which the product configuration may occur at runtime. Over the last decade, DSPL has gained the interest of researchers as a way of modelling and developing dynamically adaptive systems. We have conducted a systematic mapping to discover how variability is modelled in DSPL approaches and which information is used to guide variability binding at runtime. This paper presents the results of our systematic mapping, which can be used to identify research trends and gaps for variability management in DSPLs.

Deriving the behavior of context-sensitive systems from contextual goal models

Context-sensitive systems are flexible, capable of acting autonomously on behalf of users and to dynamically adapt their behavior. This work proposes a systematic process to derive the behavior of context-sensitive systems from contextual goal models considering the impact of non-functional requirements (NFRs). This process is centered on the incremental refinement of a goal model, obtaining different views of the system (design, contextual, and behavioral). A key contribution of this work is the Behavioral Contextual Design Goal Model, which depicts in a single artefact the operationalization of NFRs, the adaptation and the monitoring tasks.

Realidade Aumentada para o Ensino de Geometria Espacial

Este artigo discute a colaboracao entre estudantes na internet e a troca de conhecimento por meio desse canal de comunicacao. Propoe uma metodologia que visa potencializar as relacoes entre os usuarios de uma rede educacional situada num contexto especifico. Tal metodo tem como fundamento as teorias do contexto e a analise de redes sociais (ARS), para promover um mapeamento das redes estudadas.Refletir sobre curriculo escolar formal e comunidades de aprendizagem como metafora das TIC dinamizam os caminhos empiricos, construcoes criticas e aprofundamento da difusao do conhecimento como parte do processo de humanizacao/ tecnologizacao do homem. Oriundos de processos e movimentos contemporâneos, a consolidacao de ambientes computacionais nas escolas potencializa a construcao do conhecimento e a socializacao de praticas pedagogicas inovadoras. Esta investigacao assume as situacoes especificas curriculares, procura descobrir o que existe de mais essencial e caracteristico, partindo do conhecimento de curriculo e suas bases teoricas tradicionais, para a construcao da discussao sobre um curriculo em rede associada a instrumentalizacao das comunidades de aprendizagem.O sistema Moodle constitui-se atualmente numa das mais importantes ferramentas de apoio a cursos na Web. Apesar disto, seu modelo apresenta algumas deficiencias para uma estruturacao hierarquica e compartilhamento de materiais digitais entre disciplinas e turmas do seu ambiente virtual. Este artigo apresenta um estudo sobre a arquitetura central do Moodle, propondo a definicao de um novo nucleo, visando o aprimoramento destas caracteristicas.Estudo descritivo, qualitativo, com estudantes da 3a serie de Graduacao em Enfermagem de uma Universidade Publica de Sao Paulo, SP. Os participantes construiram Mapas Conceituais, por meio do software Cmap Tools®. Os dados foram coletados em um Grupo Focal e todos os sujeitos indicaram que o uso do software facilita e garante a organizacao, visualizacao e correlacao dos dados, porem houve dificuldades iniciais relacionadas ao manejo das ferramentas. Conclui-se, que o software Cmap Tools® favoreceu a construcao dos MC por seus recursos de formatacao, porem estrategias de orientacao deveriam ser implantadas. Como resultado, desenvolveu-se um manual para o uso do software Cmap Tool® em video Podcasting.Ha poucas iniciativas com respeito aos ambientes de virtuais para a divulgacao de materiais curriculares sobre modelagem matematica. Esses ambientes oferecem acesso as praticas pedagogicas em modelagem. Este trabalho apresenta um sistema Web para hospedar atividades de modelagem e materiais multimidia para descrever o desenvolvimento do ambiente de modelagem em sala de aula e apoiar outros professores na implementacao em suas praticas pedagogicas.A composicao e sequenciamento de Objetos de Aprendizagem sao discutidas neste trabalho a partir da representacao da estrutura conceitual de um dominio em termos das suas relacoes de dependencia. A composicao de Objetos de Aprendizagem e modelada a partir da estrutura narrativa de um discurso considerando-se os aspetos formais dos planos do conteudo e de expressao. O aspecto formal do conteudo da composicao e dado pelas pelos conceitos e seus relacionamentos e forma da expressao corresponde aos tipos de signos definidos pelo LOM. A estrutura da composicao obtida independe do tipo de midia utilizado e o modelo adequa-se as propostas de composicao adaptativas tanto do ponto de vista do meio como das disponibilidades de conexao.

Core Ontology to Aid the Goal Oriented Specification for Self-Adaptive Systems

[Context] Self-adaptive systems are able to modify their own behavior according to the environment in which they are inserted. Ontology is a set of concepts and relations about a specific domain and can help in the requirements communication. The core ontology for self-adaptive systems does not cover the four groups goal-oriented modeling dimensions for self-adaptive systems (goal, change, mechanism and effects). [Objective] This paper aims to complete the core ontology for self-adaptive systems in order to facilitate the requirements elicitation and specification. [Method] We had performed a comparative study in order to realize the modeling dimensions supported by the goal-oriented approaches for self-adaptive systems. So, we complete the core ontology for self-adaptive systems with the modeling dimensions concepts. [Results] As result, we present some concepts and relationships required when modeling a self-adaptive systems. [Conclusion] We obtained more complete core ontology to assist the requirements elicitation and specification for self-adaptive systems.

Usability and Software Architecture: A Literature Review

In the literature, there are available proposals that aim to contribute to bridge the gap between user interface designers and software engineers. These proposals attempt to produce architectural solutions that successfully address the usability requirements. The objective of this paper is report the planning, execution and the results of a systematic review regarding the works about usability and software architecture. We investigated the definitions, the relationship between these two areas, the impact, problems, methods, tools, reports of success or failure, and finally, the contributions of existing solutions to the academy and the industry. From the 22 selected studies, it was possible to confirm that usability has an impact on software architecture. The methods used to bridge the gap between these areas use mainly patterns, scenarios, and usability evaluation of the architecture. Furthermore, it is possible to conclude that the proposed methods and tools require more empirical evidence.

Using Tranformation Rules to Align Requirements and Archictectural Models

In previous works we have defined the STREAM strategy to align requirements and architectural models. It includes four activities and several transformations rules that could be used to support the systematic generation of a structural architectural model from goal oriented requirements models. The activities include the Preparation of Requirements Models, Generation of Architectural Solutions, Selection of Architectural Solution and Refinement of the Architecture. The first two activities are time consuming and rely on four horizontal and four vertical transformation rules which are current performed manually, requiring much attention from the analyst. For example, the first activity consists of the refactoring of the goal models, while the second one derives architectural models from the refactored i* (iStar) models. In this paper we automate seven out of the eight transformation rules of the two first activities of STREAM approach. The transformation language used to implement the rules was QVTO. We rely on a running example to illustrate the use of the automated rules. Hence, our approach has the potential to improve the process productivity and the quality of the models produced.
