1. Hardware-assisted visibility sorting for unstructured volume rendering
Harvesting the power of modern graphics hardware to solve the complex problem of real-time rendering of large unstructured meshes is a major research goal in the volume visualization community. While, for regular grids, texture-based techniques are well-suited for current GPUs, the steps necessary for rendering unstructured meshes are not so easily mapped to

3. MÉTODOS PARA OTIMIZAÇÃO DOS AJUSTES DOS REGULADORES DE TENSÃO E ZONAS DE TAP EM SISTEMAS DE DISTRIBUIÇÃO / METHODS FOR OPTIMIZATION OF THE VOLTAGE REGULATORS AND TAP ZONES IN DISTRIBUTION SYSTEMS
The new regulations in the electric sector utilities have have requested greater efficiency and quality both in terms of continuity and in conformity of the energy supplied. Electrical equipments quality, efficiency and useful life depend directly of the power quality supplied. In addition to operation of equipments, supply of energy within the limits must b

4. Uma metodologia analítico-determinística para a avaliação de desempenho no tempo de processadores de rede implementados como sistemas-sobre-silício. / An analytical deterministic methodology for the performance evaluation of network processors deployed as systems-on-chip.
O grande aumento da capacidade de integração de transistores em um único circuito integrado tem exigido grande e constante evolução na metodologia de projeto e práticas de implementação de sistemas eletrônicos embarcados. Tal capacidade de integração resultou no surgimento de sistemas sobre silício (SoCs). O projeto de tais sistemas, mais complex

5. Intelligent systems for welding process automation
This paper presents and evaluates the concept and implementation of two distinct multi-sensor systems for the automated manufacturing based on parallel hardware. In the most sophisticated implementation, 12 processors had been integrated in a parallel multi-sensor system. Some specialized nodes implement an Artificial Neural Network, used to improve photogra

6. Modelo Híbrido de Programação Paralela para uma Aplicação de Elasticidade Linear Baseada no Método dos Elementos Finitos
In the area of parallel processing there are two major programming paradigms: Shared Memory and Message Passing. Each of them fits into a specific physical model, but there are multiprocessor architectures whose mapping to one of these paradigms is not so simple. SMP clusters, for example, are built by connecting some shared memory machines through an interc

7. A LIBRARY FOR THE CREATION OF NETWORK-PROCESSORS-BASED VIRTUAL MACHINES / UMA BIBLIOTECA PARA CRIAÇÃO DE MÁQUINAS VIRTUAIS BASEADAS EM PROCESSADORES DE REDE
The aim of this work is to study, propose and implement a tool that allows the experimentation with architectures that follow the Network Processors (NP) paradigm. A generic object library was implemented, allowing the emulation of the various hardware components, such as memories, registers, arithmetic-and-logical units, control units etc., that are commonl

11. SEQUENTIAL AND PARALLEL STRATEGIES OF GRASP WITH PATH-RELINKING FOR THE 2-PATH NETWORK DESIGN PROBLEM / ESTRATÉGIAS SEQÜENCIAIS E PARALELAS DE GRASP COM RECONEXÃO POR CAMINHOS PARA O PROBLEMA DE SÍNTESE DE REDES A 2-CAMINHOS
Let G = ( V, E) be a connected undirected graph , where V is the set of nodes and E denotes the set of edges. A 2- path between nodes (s,t)is a sequence of a most two edges connecting them. Given a non-negative weight function associated with edges of G and a set D of origin- destination pairs of nodes, the 2-path network design problem (2PNDP) consists in f

12. Um ambiente para geraÃÃo automÃtica de biblioteca de componentes de comunicaÃÃo em sistemas embarcados distribuÃdos
design environment that support these kind of projects. The co-design of distributed embedded systems is an even more challenger task, because each methodology phase has to take into consideration the physical restrictions imposed by the systems features. One of the distributed embedded systems co-design challenges is the generation of communication between
