13. Efeitos da Segmentação em Sistemas Híbridos ANN+HMM
The Hidden Markov Models has become the widely used speech recognition framework due to its solid probabilistic approach. However, this robustness is damaged when the Markov chains are trained under the maximum likelihood method, which is poor in discriminative power. Until now several efficient techniques and algorithms have been developed to increase the p

14. DEVELOPMENT OF METHODS AND ALGORITHMS FOR EVALUATION AND OPTIMIZATION OF THE RELIABILITY IN NETWORKS DISTRIBUTION / DESENVOLVIMENTO DE MÉTODOS E ALGORITMOS PARA AVALIAÇÃO E OTIMIZAÇÃO DA CONFIABILIDADE EM REDES DE DISTRIBUIÇÃO
O sistema de distribuição é parte extremamente importante do fornecimento de energia. Ao mesmo tempo, as redes de distribuição, na maioria das vezes com configuração radial, são os elementos mais vulneráveis comparado com o sistema de transmissão e sub transmissão. A experiência mundial mostra que até 80% de todas as interrupções no fornecimen

15. ALGORITHM DEVELOPMENT FOR THE RELIABILITY OPTIMIZATION ON DISTRIBUTION NETWORKS / DESENVOLVIMENTO DE ALGORITMOS PARA OTIMIZAÇÃO DA CONFIABILIDADE DE REDES DE DISTRIBUIÇÃO
New regulations of the electricity sector have requested greater efficiency from the power utilities in the performance of their distribution systems, requiring more rigorous quality and continuity energy levels. This work has the purpose of stating the best way to model the integer indicators of reliability for electric systems, financial resources and mate

16. Um algoritmo para estimação de estado em alimentadores de distribuição de energia elétrica com base no método da soma de potências
Most algorithms for state estimation based on the classical model are just adequate for use in transmission networks. Few algorithms were developed specifically for distribution systems, probably because of the little amount of data available in real time. Most overhead feeders possess just current and voltage measurements at the middle voltage bus-bar at th

17. Avaliação da acurácia das temperaturas da superfície do mar obtidas por satélite para a região. sul-sudeste da costa brasileira / South Brazil satellite sea surface temperature accuracy assessment
The accuracies of the global Advanced Very High Resolution Radiometer (AVHRR) split-window Sea Surface Temperature (SST) algorithms, derived from NOAA 11 and 12 satellites, were determined from comparisons with a match-up data set of COROAS project drifting buoy measurements for the southeast coast of Brazil, in the western part of the South Atlantic Ocean.

18. Avaliacao de dados MSS/Landsat para identificacao e delimitacao de manguezais na area de Cananeia-Iguape (Estado de Sao Paulo) / Assessment of data MSS / Landsat for identification and delimitation of mangroves in the area of Cananeia-Iguape (Sao Paulo state)
Mangroves are considered to be responsible for the high biological productivity of coastal enviroments. In spite of their ecological importance, their spatial distribution patterns are poorly known and this fact restricts the effectiveness of management regarding protective measures against devastation by man. The application of satellite remote sensing tech

19. Identification and handling of artifactual gene expression profiles emerging in microarray hybridization experiments
Mathematical methods of analysis of microarray hybridizations deal with gene expression profiles as elementary units. However, some of these profiles do not reflect a biologically relevant transcriptional response, but rather stem from technical artifacts. Here, we describe two technically independent but rationally interconnected methods for identification
