13. Contribuições para a análise e simulação de redes ópticas: aspectos de Engenharia de Tráfego, restauração dinâmica e conversão de comprimentos de onda / Contributions for the analysis and simulation of optical networks: aspects of traffic engineering, dynamic restoration and conversion of wavelenghts
The Wavelength Division Multiplexing (WDM) technology as well as both the introduction of all optical OXCs (Optical Cross Connect) and OADMs (Optical Add/Drop Multiplexer) may provide the optical network with the networking function, i.e, the capacity to manipulate wavelengths in order to implement their routing. This possibility implies a new type of relati

14. SYNTHESIS METHODOLOGY FOR SIMPLIFIED ZVT TOPOLOGIES APPLIED TO BIDIRECTIONAL PWM POLES / METODOLOGIA DE SÍNTESE DE TOPOLOGIAS ZVT SIMPLIFICADAS APLICADAS A PÓLOS PWM BIDIRECIONAIS
Among the soft-switching techniques, the zero-voltage-transition (ZVT) technique has been accepted well by the industry due its attractive characteristics, such as simplicity, low losses in the auxiliary commutation circuit (ACC), operation with soft-switching for a wide load range, and closest operation to the PWM converter counterpart. In three-phase volta

15. Uma Proposta de MÃtricas para Avaliar Modelos i*
The Goal-Oriented Requirement Engineering has shown a promising way to describe software systems. It provides a natural mechanism to structure complex requirement documents through goals providing a mechanism to justify the existence of the requirements and facilitate the management of conflicting requirements. In this context, different approaches that use

17. Gerência de projetos de software livre no framework SAFE
The open source software theme has become an important area of Software Engineering study and research, earning its space as a ramification of the Traditional Software Engineering, defined as Open Source Software Engineering (OSSE). Several communities have obtained success in developing open source software based solutions, among them: Mozilla, Apache and L

18. Proposta de método para gestão de requisitos de sistemas integrando modelagem de negócio e linguagens formais. / Proposal for management system requirements method integrating business modeling and formal languages.
Despite new and effective software engineering techniques, system development projects are likely to have the same problems that affect the management support software. Delivery delay, above budget and not fitting the real needs of end users or the organization that is funding the system development, are the most common problems. The latter problem is the on

19. Estudos qualitativos para elicitaÃÃo de requisitos: uma abordagem que integra anÃlise sÃcio-cultural e modelagem organizacional
It is known that to adequately obtain software requirements it is necessary to understand the human activities of the social and organizational contexts where the future systems will be used. Traditional ethnomethodological approaches of qualitative social studies provide a detailed description of human activities. However, the rethorical aspect these approa

20. O QFD como foco da satisfaÃÃo dos clientes: a qualidade no desenvolvimento de produtos e serviÃos para a criaÃÃo de software
This study discusses the application of QFD (Quality Function Deployment) methodology as a focus on customer satisfaction, emphasizing the quality parameters on products and services development in software creation. The QFD, indicated as a path to organize products progress at operational level, specifically on software development. This faced on one hand,

21. TÉCNICO VS. USUÁRIO: UMA ANÁLISE DO PROCESSO COMUNICACIONAL NA ENGENHARIA DE REQUISITOS DE SOFTWARE
This research analyzes a practical and a communicational problem associated to software development which takes place before the program begins to be created: the software industry professionals say that the user does not know what he wants, due to frequent change requests associated to the software requirements that originate volatile requirements. This wor

22. Improving traceability in agent oriented development
Requirements engineering has argued that in order to successfully develop complex software systems, it is necessary to support the modeling process with traceability mechanisms and tools. Requirement Traceability refers to the ability to ensure continued alignment between stakeholdersâ requirements and various outputs of the systems development process. A r

23. Avaliação do sensor de umidade TOPDEA no manejo da irrigação. / Evoluation of the moisture sensor topdea for irrigation scheduling.
The scientific community, in recent years, has intensified studies to measure the impacts to the environment caused by pollution, mainly the adverse effects to air and water. The fact that less than 1% of the global water resources is comprised of drinking water and available at the surface of the earth makes it a commodity of conflict. According to the FAO

24. O uso da simulação no suporte a implementação da estrutura de controle supervisório
Abstract: The growth of competitiveness in enterprises has forced them to reduce more the releasing time of their products. Consequently, the enterprise and academy s effort in providing techniques and tools for the reconfiguration of its systems is in force. A manufacturing system is a classical example of a Discrete-Event System (DES), for its dynamics dev
