1. Experimentos em simulações paralelas do Dilema do Prisioneiro com n jogadores. / Experiments in parallel simulations of the n-player Prisoner\ s Dilemma.
O Dilema do Prisioneiro com n jogadores é um problema que ilustra a dificuldade na formação da cooperação em sociedades de indivíduos racionais. Diversos trabalhos foram feitos no sentido de compreender melhor os fatores que influenciam o surgimento e a evolução da cooperação nessas sociedades, sendo que muitos desses mostraram que a simulação de

2. Sequential and parallel approaches to reduce the data cube size.
Since the introduction of Data Warehouse (DW) and Online Analytical Processing (OLAP) technologies, efficient computation of data cubes has become one of the most relevant and pervasive problems in the DW area. The data cube operator has exponential complexity; therefore, the materialization of a data cube involves both huge amount of memory and substantial

4. Uma Abordagem, baseada em framework e na técnica de descrição formal Estelle, para o desenvolvimento de sistemas de arquivos paralelos distribuídos. / An approach, based on framework and the formal description technique Estelle, for the development of distributed parallel file systems.
The constant increase of processing speed, mainly due to the use of a large number of processors, has allowed an improvement in the design and building of parallel computation systems. However, the performance of several types of applications is affected by the latency originated from Input/Output operations on data. In order to solve this problem parallel f

6. ProgramaÃÃo paralela de alto nÃvel e eficiente sobre arquiteturas distribuÃdas
New technological paradigms have emerged in high-performance computing since last decade. The consolidation of distributed architectures and the recent advances in the state-of-the-art performance of processor and interconnection networks gave birth to clusters, conventional computer networks that can compete with supercomputers in its niche of applications,

9. Neural networks counting chimes.
It is shown that the ideas that led to neural networks capable of recalling associatively and asynchronously temporal sequences of patterns can be extended to produce a neural network that automatically counts the cardinal number in a sequence of identical external stimuli. The network is explicitly constructed, analyzed, and simulated. Such a network may ac

10. How the owl resolves auditory coding ambiguity
The barn owl (Tyto alba) uses interaural time difference (ITD) cues to localize sounds in the horizontal plane. Low-order binaural auditory neurons with sharp frequency tuning act as narrow-band coincidence detectors; such neurons respond equally well to sounds with a particular ITD and its phase equivalents and are said to be phase ambiguous. Higher-order n

11. Exploring Issues of Quality of Service in a Next Generation Internet Testbed: A Case Study Using PathMaster
This case study describes a project that explores issues of quality of service (QoS) relevant to the next-generation Internet (NGI), using the PathMaster application in a testbed environment. PathMaster is a prototype computer system that analyzes digitized cell images from cytology specimens and compares those images against an image database, returning a r
