1. Simulador eletromagnético em um ambiente de grades computacionais / Eletromagnetic simulator in a grid computing environment
The aim of this work is to develop the Pre and Post-Processing stages from an electromagnetic simulation suite, called SSAR-BR, and also a grid computational environment, which permits the execution of large electromagnetic problems. The processing stage, based in the Finite Difference Time Domain (FDTD) method, has been already developed as part of a doctor

2. Performance evaluation of a discovery and scheduling protocol for multihop ad hoc mobile grids
Despite the many research efforts addressing the integration of mobile nodes into grids, only a few of them have considered the establishment of mobile grids over wireless ad hoc networks (hereafter, mobile ad hoc grids). Clearly, such grids need specialized resource discovery and scheduling mechanisms. To the best of our knowledge, though, the research on t

3. Acesso Móvel aos Serviços do Middleware InteGrade / Mobile Access Services Middleware InteGrade
Mobile computing technologies and wireless networks have evolved very quickly. Nowadays, many of the portable devices have significant processing power, storage and communication capacity. At the same time, grid computing technology became an important tool for collaborative work among users and organizations enabling the sharing of computing resources and s

4. Uma proposta de um modelo de confiança computacional para grupos em sistemas distribuídos
A representação da confiança e da reputação em sistemas computacionais é um desafio em sistemas distribuídos. Nesses sistemas, a aplicação da confiança e da reputação busca contribuir com a segurança da informação, de forma a dar uma garantia mínima de realizar transações seguras sem uma autoridade central de controle. Nessa perspectiva, a

5. UM PROTOCOLO PARA DESCOBERTA E SELEÇÃO DE RECURSOS EM GRADES MÓVEIS AD HOC / A PROTOCOL FOR RESOURCE DISCOVERY AND SELECTION IN MOBILE AD HOC GRIDS
In the last few years, the use of mobile devices in computational grids has seen a growing interest. Nevertheless, a more challenging issue, the dynamic establishment of mobile grids on wireless ad hoc networks, has been so far only partially addressed. The first contribution of this thesis is the proposal of a software architecture for mobile grids that can

6. MAG: uma grade computacional baseada em agentes móveis / MAG: a based computational grating in agents you move
In recent years, Grid computing has emerged as a promising alternative to the integration and sharing of multi-institutional resources. However, constructing a Grid middleware is a complex task. Developers must address several design and implementation challenges, such as: ecient management and allocation of distributed resources, dynamic task scheduling, hi

7. Evidence grids with omnidirectional stereovision for mobile robots. / Grades de evidência com visão estéreo omnidirecional para robôs móveis.
Autonomous mobile robots depend on information acquired with its sensors to make decisions during its task. The use of vision systems provide a large amount of data about the environment in which the robot is. Particularly, an omnidirectional vision systems provide information in all directions of the environment to the robot with just one image. Through the
