1. Projeto de um codificador/decodificador Viterbi integrado / Integrated Viterbi encoder/decoder design
Com o aumento da densidade de transistores devido aos avanços na tecnologia de fabricação de IC, que usam cada vez dimensões menores e a possibilidade de projetar chips cada vez mais complexos, ASIC (Application Specific Integrated Circuit) podem de fato integrar sistemas complexos em um chip, chamado de System-on-chip. O ASIC possibilita a implementaç�

2. DevC: uma linguagem de suporte ao desenvolvimento concorrente de device drives e modelos de controladores de entrada e saÃda
Modern electronic products incorporate several features, combining mobility, computational power, a great capacity for communication and facility for interfacing. Nevertheless, integrating such functionalities increases the complexity of the design. The design of such products includes an embedded system that implements their functionalities in a combined so

3. Proposta e implementação de uma arquitetura reconfigurável híbrida para aplicações baseadas em fluxo de dados
The increase of applications complexity has demanded hardware even more flexible and able to achieve higher performance. Traditional hardware solutions have not been successful in providing these applications constraints. General purpose processors have inherent flexibility, since they perform several tasks, however, they can not reach high performance when

4. AN INTERCEPTOR BASED ON AOP TO TREAT TRANSVERSAL INTERESTS IN SERVICES WEB / UM INTERCEPTADOR BASEADO EM AOP PARA TRATAR INTERESSES TRANSVERSAIS EM SERVIÇOS WEB
This research currently presents the description of a project in development in the laboratory of intelligent systems (LSI), of the Federal University of the Maranhão (UFMA). The current Middlewares ESB such as the BEA Web Logic, BizTalk, Mule ESB and similars, does not possess a semantics for the treatment of the crosscutting concerns neither before, durin

5. T&D-bench : explorando o espaço de projeto de processadores em ensino e em pesquisa
Uma metodologia de modelagem para a exploração do espaço de projeto de processadores é apresentada. A exploração do espaço de projeto constitui uma das etapas do fluxo de projeto dos atuais processadores de alto desempenho e de sistemas embarcados, que auxilia os projetistas no tratamento da complexidade inerente ao processo contemporâneo de projeto

6. 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

7. Incorporação de qualidade de serviço no modelo de serviços web / Inclusion of quality of service into the web service model
Although the Web service technology allows the development and execution of distributed applications, it still lacks facilities to deal with Quality of Service (QoS). Consumers may require services with particular non-functional characteristics and expect quality level guarantees. The goal of this thesis is to propose an extended Web service architecture sup

8. Estimativa de consumo de energia de cÃdigo ANSI-C para sis- temas embarcados: uma abordagem baseada em simulaÃÃo estocÃstica
Embedded Systems are present in most daily activities with many different purposes. Generally, embedded systems have several design constraints, such as memory size, power source, CPU speed, and so on. Over the last years, power consumption has been receiving particular attention from scientific community since several embedded devices rely on battery as pow

9. Uma proposta de arquitetura de linha de produto para sistemas de gerenciamento de workflow
A tecnologia de workflow vem apresentando um grande crescimento nos últimos anos. Os Workflow Management Systems (WfMS) ou Sistemas de Gerenciamento de Workflow oferecem uma abordagem sistemática para uniformizar, automatizar e gerenciar os processos de negócios. Esta tecnologia requer técnicas de engenharia de software que facilitem a construção desse

10. Crosscutting interfaces for aspect-oriented modeling
Aspect-oriented software development promotes improved separation of concerns by introducing a new modular unit, called aspect, for the modularization of crosscutting concerns. As a new kind of modular unit, aspects should have explicit interfaces that describe the way they interact with the rest of the system and how they affect other modules. This interact

11. Uma abordagem para detecção de ataques distribuídos e múltiplas etapas baseada na composição de serviços web voltados para à segurança
With the wide use of the Internet and the proliferation of technologies to reproduce attacks, institutions have become target of a variety of intrusion activities, ranging from simple port scans to complex attacks, such as distributed denial of services and worms. Aiming to develop solutions to minimize the intruders chances to succeed in his/her activities,

12. Nested-CA: um fundamento para modelagem de mudança de uso e cobertura do solo em multiplas escalas / Nested-ca: a foundation for multiscale modelling of land use and land cover change
This work presents the mathematical foundations of the Nested Cellular Automata (nested-CA) model, a model of computation for multiple scale Land Use and Land Cover Change studies. The main properties of nested-CA model are described and compared to the agent-based and cellular automata models of computation. The nested- CA model has been implemented in a so
