13. Um ambiente de animacao dinamica de corpos rigidos
The general purpose of this work is the study of the fundamentals of the computer animation and the object-oriented development of a procedural animation system for visualization and dynamic simulations of 3D scenes in science and engineering applications. In such system an animation is specified by an animation language AL and an animation API.AL was derive

14. Cordel: memória e comunicação em rede / Cordel: memory and network communication
The first fair pamphlets were printed in Brazil just over one hundred years ago. Between tradition and invention a wider network was spread around the country and was called cordel. A cordel network, index of memory and collective creation has also expanded in time. Its production knew other communication technologies until the interconnected computer networ

16. MULTI-RESOLUTION OF OUT-OF-CORE TERRAIN GEOMETRY / MULTI-RESOLUÇÃO DE GEOMETRIA DE TERRENOS ARMAZENADOS EM MEMÓRIA SECUNDÁRIA
The visualization of large terrains is a challenging Computer Graphics issue. The number of polygons required to faithfully represent a terrain`s geometry can be too high for real-time visualization. To solve this problem, a multiresolution algorithm is used to feed the graphics processor only with the most important polygons, without visual quality loss. Th

17. Analogic memories characterization implemented with floating gate MOS transistors / Caracterização de memorias analogicas implementadas com transistores MOS floating gate
Monolithic integration of memories and analog circuits ,in the same die offers interesting advantages like: smaller application boards, higher robustness and mainly lower costs. Today, a profitable integration of these kind of circuit can only be possible using conventional CMOS technology, which allows efficiently extraordinary levels of integration. Thus,

18. Controle dinâmico de recursos em sistemas operacionais
One of the main functions of the operating systems is to manage the computer resources. A network operating system has the same duty, however, the quantity of resources that should be manage is bigger. Even so, COTS operating systems supply only limited mechanisms of resources management, where is not possible impose contraints or privileges of access to the

19. Desenvolvimento de um protótipo de aquisitor portátil de sinal mioelétrico / Development of a prototype of data logger to myoelectric signal
Electromyography is the study of the muscular function by the acquisition of the electric sign that the muscles produce. Most of the equipments for reception of the sEMG is bench models, in other words, they have a size that disables that the patient can carry it during the period of acquisition of the sign and it is also necessary that a connected computer

20. Um processo Otimizado de produção de mapas da radiação cósmica de fundo em microondas / An optimized process of production of cosmic microwave backgroud radiation maps
The current work describes the optimization and parallelization of the software for the production of Cosmic Microwave Background (CMB) radiation maps in a distributed memory architecture. Initially, the Fortran code was ported to Fortran 90 and to High Performance Fortran (HPF) and run in a SMP (Shared Memory Processor) machine. In order to provide timing i

21. BUILDING AN ARCHITECTURE STRATEGIC CORPORATE MEMORY BASED ON A BUSINESS MODEL / CRIANDO UMA ARQUITETURA DE MEMÓRIA CORPORATIVA BASEADA EM UM MODELO DE NEGÓCIO
This work presents a proposal for building corporate memory architecture. It has three layers: sources, middleware and repositories. First, we create an conceptual enterprise model, named Organizational Baseline (OB), based on theories of business management and organized in accordance with an approach of ontology. Second, we use multi agents system as a mea

22. SimulaÃÃo de reservatÃrio de petrÃleo em arquiteturas paralelas com memÃria distribuida
New codes have been developed for the solution of large scale models in reservoir simulations with high performance computing. This work shows the development of a petroleum reservoir simulator using distributed memory models for parallel computers. A two phase oil/water Black-Oil model was implemented and the resulting equations are discretized by ânite di

24. Serviço de persistência para ambientes distribuídos explorando os recursos do repositório de interfaces
- This dissertation presents a new approach to the persistence of objects in distributed environments. Service persistence for a SICSD architecture was the focus of this research. SICSD architecture has shown itself to be both flexible and dynamic in the distributed environments of the satellite control software used at the Brazilian National Space Research
