1. Solução baseada em gerenciamento de processos de negócios para circuitos virtuais inter-domínio / Solution based on business process management for inter-domain virtual circuits
O estabelecimento de Circuitos Virtuais (CVs) é uma solução bastante utilizada para garantir requisitos de qualidade de serviço para aplicações que trafegam na rede (e.g., transmissão de altas taxas de dados com baixa latência). Anteriormente, esses CVs eram estabelecidos manualmente a partir da troca de mensagens (via email e telefone) entre adminis

2. [email protected] um rolê pelas ruas da cultura digital
Rolê, in urban slang means to walk around, to go for a walk. Following this definition, this research walks through files posted by urban writers, in the great computer‟s world wide net. The technological advance allowed great changes in the way we communicate to each other. The spaces for human relationship have spread, and are also cyberspace and th

3. Ambiente de apoio ao projeto de circuitos integrados baseado no world wide web / A world wide web based integrated circuits design environment
Atualmente, o use de ferramentas de apoio ao projeto de circuitos integrados é indispensável, devido a complexidade desses circuitos que aumenta incessantemente. O presente trabalho discute um modelo para integração de ferramentas em um ambiente único - formando um framework - com o objetivo de acelerar o processo de concepção dos circuitos através d

4. Desenvolvimento e aplicações de sensores de campo magnético por indução : [dissertação]
This work addresses the development of magnetic elds meters at low frequencies. The sensing elements used are induction coils and the Chattock-Rogowski coils, both with non-ferromagnetic cores. Theoretical and experimental studies on the working principle of these sensors are presented, considering the practical aspects related to their non-ideal behavior. T

5. Desenvolvimento de sistemas portáteis de monitoramento eletroquímico. / Development of portables electrochemical monitoring systems.
This work presents the development of two different portable electrochemical detection systems. Both systems are applicable in environment and biomedical areas. The electrochemical detection techniques have many interesting advantages, when compared to other detections techniques, such as good sensitivity, good selectivity, and low maintenance cost. The dete

6. A VPN (Virtual Private Network) design based on reconfigurable computing and applied to mobile robots / Projeto de uma VPN(Rede Privada Virtual) baseada em computação reconfigurável e aplicada a robôs móveis
This work designs a system that implements a VPN using FPGA (Field Programmable Gate Array) reprogrammable circuits, which are the basis of reconfigurable computing. VPNs use cryptography to allow private communication between parts. In this manner, the computational cost of the cryptography is handled by the hardware, achieving great performance and allowin

7. Phoenix um framework para trabalhos em síntese de alto nível de circuitos digitais
Este trabalho descreve o desenvolvimento de um framework de código aberto para síntese de circuitos digitais, para uso em projetos de hardware/software co-design. O framework consiste de um compilador que aceita ANSI C como código fonte e que permite a construção de um dado sistema e sua execução em hardware. Este compilador, intitulado Phoenix, permi

8. o uso do paradigma restrições geométricas para apoio a projetos de instalações elétricas / Using geometric constraint approach to support electri- cal installation design
Nowdays, a growth has been observing in the software use CAD (Computer-Aided Design) and CAE (Computer-Aided Engineering) for design in area of the architecture, engineering and building . The professional makes use of those tools that automate and accelerate design routines propitiating more time to improve the quality of them. However, most of the current

9. Proposta de um modelo de seguranÃa para VPNs na interligaÃÃo de redes corporativas
A Virtual Private Network - VPN is a protected connection, built for the private use of the enterprise, over a shared public network. A VPN uses security protocols, cryptography technologies and authentication to guarantee characteristics of a private and dedicated network to enterprises that use a not-trustworthy infrastructure, as the Internet, for interco

10. The brain decade in debate: VI. Sensory and motor maps: dynamics and plasticity
This article is an edited transcription of a virtual symposium promoted by the Brazilian Society of Neuroscience and Behavior (SBNeC). Although the dynamics of sensory and motor representations have been one of the most studied features of the central nervous system, the actual mechanisms of brain plasticity that underlie the dynamic nature of sensory and mo

11. Projeto e construção de uma porta universal CMOS em logica ternaria
In this work we developed a universal gate in temary logic through Post algebra; using this gate we could develop some well known circuits from binary logic like Flip-Flops and Adders. These circuits were simulated using Spice and the Lay-Out was developed using tools like Tanner and L YS; to construct the integrated circuit we use a foundry that we already
