1. PRO-ELICERE: A Hazard Analysis Automation Process Applied to Space Systems
ABSTRACT In the last decades, critical systems have increasingly been developed using computers and software even in space area, where the project approach is usually very conservative. In the projects of rockets, satellites and its facilities, like ground support systems, simulators, among other critical operations for the space mission, it must be applied

3. Simulação do processo de adsorção psa para separação da mistura etanol-água / Simulation of the adsorption process psa for separation of ethanol-water mixtures
One of the problems with ethanol production is the high energy cost which is associated with the separation of ethanol due to of excess water and the existence of an azeotrope in the mixture ethanol-water, by conventional distillation the mixture can be separated up to 95% weight. Currently, there is great interest in the development of technological process

4. Implementações sequencial e paralela de um novo algoritmo para a simulação de elementos e compostos magnéticos
The magnetic phenomena are widely used in many devices, such as electronic, data storage and telecommunications devices. The understanding of this phenomenon is therefore of great interest to support the improvement and development of new technologies. To better understand the magnetic phenomena, it is essential to study interactions at nano scale. When magn

5. Desenvolvimento de uma ferramenta computacional para aplicação em métodos de elevação por bombeio centrífugo submerso
The Electrical Submersible Pump (ESP) has been one of the most appropriate solutions for lifting method in onshore and offshore applications. The typical features for this application are adverse temperature, viscosity fluids and gas environments. The difficulties in equipments maintenance and setup contributing to increasing costs of oil production in deep

6. INFRAESTRUTURA PARA SIMULAÇÃO DE PROCESSOS DE SOFTWARE BASEADA EM METAMODELOS DE DINÂMICA DE SISTEMAS
Better results are achieved, in projects involving software development, when the responsible manager has some previous experience in projects. However, it is impossible for educational institutions to educate their students by creating pilot projects for each student, due to problems with the time scale, costs and staff. An alternative way study problems th

7. Restructuring of ArchC for integration to TLM-based project / Reestruturação de ArchC para integração a metodologias de projeto baseadas em TLM
The advent of SoCs (Systems-on-Chip) lead to the development of project methodologies based on TLM (Transaction-Level Modelling), which consist of several modelling layers between pure specifications and synthesizable RTL (Register Transfer Level ) descriptions, making the complexity of such systems more manageable. Considering that those systems usually hav

8. A platform development framework and a debugging mechanism based on computacional reflection / Um framework de desenvolvimento de plataformas e um mecanismo de depuração baseado em reflexão computacional
Digital systems are becoming more and more complex through the years, putting general purpose processors together with specialized hardware and buses into the same silicon die, due to power, area and performance constraints. In order to deal with this complexity and a short time-to-market, designers are adopting high level hardware descriptions, based on lan

9. Modelagem e simulação de barramentos com systemC / Modeling and simulation of bus using SystemC
The system-on-chip era is creating new challenges to the system design. There is an increasing demand for smaller electronic devices with more features and reduced time to market. To face these new challenges is necessary to introduce new methodologies and development techniques. Buses are important elements for connecting devices in a complex system. To inc

10. Fluid animation by cellular automata and particles systems / Animação de fluidos via autômatos celulares e sistemas de partículas
The past two decades showed a rapid growing of physically-based modeling of fluids for computer graphics applications. Techniques in the field of Computational Fluid Dynamics (CFD) have been applied for realistic fluid animation for virtual surgery simulators, computer games and visual effects. In this approach, since the equation is solved numerically the n

11. Modelos de depleção para reservatorios de oleo espumo / Depletion models for foamy oil reservoirs
Fields in Canada and Venezuela, which contain foamy oil reservoirs, have exhibited a primary oil recovery on the order of 10 to 15 % greater than the recovery estimated by black-oil simulators. Besides the high oil recovery, other unusual characteristics have been observed, as low gas-oil ratio and high reservoir pressure maintenance. Such discrepancy betwee

12. Estudo sobre a variação dos parâmetros do Tree Load Balancing Algorithm / Study about the variation of the Tree Load Balancing Algorithm parameters
In locally distributed systems, when plenty of tasks are randomically submitted to network computers where certain computers may be heavily loaded, while others lightly loaded, load balancing algorithms may be used on to homogenize and optimize the resources allocation, and hence improve the computer performance. Later on, the distributed systems evolution m
