1. Dynamic load-balancing : a new strategy for weather forecast models
Weather forecasting models are computationally intensive applications and traditionally they are executed in parallel machines. However, some issues prevent these models from fully exploiting the available computing power. One of such issues is load imbalance, i.e., the uneven distribution of load across the processors of the parallel machine. Since weather

2. Análise,Simulações e Aplicações Algorítmicas de Caminhadas Quânticas / Analysis,Simulations and Algorithmic Applications of Quantum Walks
Quantum computing is a model of computation based on the laws of quantum mechanics, which can be used to develop faster algorithms. The development of efficient quantum algorithms, however, is a highly challenging task. A recent successful approach is the use of quantum walks. In this work, we have studied the quantum walk on the hypercube, obtaining the exa

3. Proposta de melhoria de tempo de resposta para o protocolo FTT-CAN : estudo de caso em aplicação automotiva
Embedded computing systems have become widely used in many areas. The greater part of those systems has time constraints and therefore they can be characterized as real time embedded systems. Nowadays, distributed computing has reached the embedded application, where some fieldbuses are already being used as communication platforms. Some important researches

5. 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

6. Depuração simbólica extensível para sistemas de objetos distribuídos / Extensible symbolic debugging for distributed object systems
After over thirty years of intense research, debugging distributed systems is still regarded as a difficult task. While this situation could be partially blamed on the fact that concurrent executions are complex, the fast pace of evolution witnessed with distributed computing technologies have also played its by shortening the lifespan of many potentially us

8. Arquitetura pipeline reconfigurável através de instruções geradas por programação genética para processamento morfológico de imagens digitais utilizando FPGAs / Reconfigurable pipelined architecture through instructions generated by genetic programming for morphological image processing using FPGAs
Mathematical morphology supplies powerful tools for low level image analysis, with applications in robotic vision, visual inspection, medicine, texture analysis and many other areas. Many of the mentioned applications require dedicated hardware for real time execution. The task of designing manually morphological operators for a given application isnot alway

9. Estudo comparativo entre metaheutísticas populacionais com tamanho da população variável
This work introduces four novel population-based heuristic algorithms, whose population size varies along the execution, which are aimed at solving problems of search and numerical optimization. These algorithms are extensions of the standard models of two metaheuristics recently proposed in the literature, which have been successfully applied in different f

10. ESTUDO DO CICLO DIÁRIO DA CAMADA LIMITE PLANETÁRIA ATRAVÉS DA SIMULAÇÃO DOS GRANDES TURBILHÕES / STUDY OF DAILY CYCLE OF PLANETARY BOUNDARY LAYER BY LARGE EDDY SIMULATION
The PBL is the region on the troposphere characterized by existence of turbulence (BUSINGER, 1981). Turbulent flow is that when the fluctuations of the variables that describe the flow are amplified in time and space (LANDAU; LIFSHITZ, 1959). The study of the planetary boundary layer (PBL) through the computational fluid dynamics, particularly the large eddi

12. QUANTUM-INSPIRED EVOLUTIONARY ALGORITHMS FOR PROBLEMS BASED ON NUMERICAL REPRESENTATION / ALGORITMOS EVOLUTIVOS COM INSPIRAÇÃO QUÂNTICA PARA PROBLEMAS COM REPRESENTAÇÃO NUMÉRICA
Since they were proposed as an optimization method, the evolutionary algorithms have been successfully used for solving complex problems in several areas such as, for example, the automatic design of electronic circuits and equipments, task planning and scheduling, software engineering and data mining, among many others. This success is due, among many other
