Utilização de Redes Neurais na Manutenção Pró-Ativa de Índices

This paper presents a mechanism, denoted Neural-PIM, for proactive index management based on the use of artificial neural networks. Neural-PIM is DBMS-independent, runs continuously and with no DBA intervention. Additionally, Neural-PIM is based on a four steps approach: (1) monitoring the workload submitted to DBMS, (2) identifying a set of time consuming queries and discovery the more appropr...

Utilização de técnicas de análise estática e dinâmica para otimização de aplicações de propósito geral em GPUs

We have witnessed large advances in the use of devices designed speci cally for running parallel applications. Examples of this class of hardware are graphics processing cards, as those produced by NVIDIA. The use of GPUs to accelerate general purpose applications gave rise to a new line of parallel applications development, popularly known as GPGPU. Although recent, GPGPU applications achieved...

Utilização de Imagens de Sensoriamento Remoto de Alta Resolução para Realizar a Contagem de Copas em Povoamento de Eucalyptus spp

The present work aims at performing automatic tree crown counting in planted Eucalypt forests. High resolution remote sensing imagery and digital image processing using Lee Filters and the unsupervised classification algorithm ISODATA were used. The classification result that best extracted tree crowns was exported to a GIS for tree counting. The resulting number of trees was compared to the nu...

Utilização do Caminhamento Aleatório na Identificação de Características de Documentos na Língua Portuguesa

Due to a great amount of web-stored texts, the text mining area has been coming through a series of studies in order to optimize the automatic classification of texts. In this context, this study is aimed at testing a technique to assess the weight of terms named random-walk and applying it to Portuguese language texts. This technique uses the co-occurrence of the terms as a measure between the...
