25. Design of CAN-based distributed control systems with optimized configuration
A current trend in distributed control systems is the application of communication networktechnologies such as CAN - Controller Area Network. A recent utilization approach ofthese technologies is the networked control systems (NCS). The fundamental challenges inthe development of NCS are the analysis of the network delay effects and the prediction of the tim

28. Hardware/Software codesign of particle filter for real time localization of mobile robots / Co-projeto de hardware/software do filtro de partículas para localização em tempo real de robôs móveis
Sophisticated techniques for estimation of models based on simulation, particle filters or Sequential Monte Carlo Methods, were recently used to solve many difficult problems in the field of mobile robotics. However, the success of particle filters was limited to the computation of parameters in low dimensionality spaces. The current research efforts in mobi

31. Uma arquitetura de controle de qualidade de serviço aplicada a redes heterogêneas e serviços convergentes. / An architecture for QoS control applied to heterogeneous networks and convergent services.
One of the targets of the next generation communication systems is to provide access to any service, to any user, anytime, anywhere, regardless the access network technology or type of user device (mobile phone, PDA, personal computer, and so on). This scenario is called convergence of services by heterogeneous networks, and in such scenario quality of servi

36. Collaborative Journalism in Digital Networks: Communication Strategy in the Cyberspace. The case of Zero Hora.com / Jornalismo Colaborativo em Redes Digitais: Estratégia Comunicacional no Ciberespaço. O caso de Zero Hora.com
This study was based in the idea that digital participative systems lead to changes in the institutionalized territory of journalism. The search for evidences of this process begins in the first chapter, with the analysis of journalism as an institutionalized territory and the processes of deterritorialization, reterritorialization and unterritorialization.
