1. O uso de redes neurais auto-organizÃveis na anÃlise da transferÃncia de conhecimentos prosÃdico em aprendizes brasileirios de lÃngua inglesa / The use of self-organizing artificial neural networks for the analysis of prosodic knowledge in Brazilian learner of English
The objective of this dissertation was to investigate how the prosodic knowledge is organized in an early stage of L2 acquisition in Brazilian learners of English with the help of a connectionist neural network. The approach proposed in this research is first, to quantify the utterances of L2 learners in the form of LPC coefficients and other linguistic/phon

2. Redes neurais artificiais aplicadas ao problema da localização em ambientes fechados
This thesis addresses the indoor location problem using on artificial neural networks-based techniques. In this system, the received signal strength information (RSSI) provided by standard network wireless interfaces are the basis for mobile devices location prediction. Traditional methods of indoor location have several undesirable characteristics, such as

3. A tabela periódica dos elementos químicos prevista por redes neurais artificiais de Kohonen
Although several chemical elements were not known by end of the 18th century, Mendeleyev came up with an astonishing achievement: the periodic table of elements. He was not only able to predict the existence of (then) new elements but also to provide accurate estimates of their chemical and physical properties. This is certainly a relevant example of the hum

4. REACTIVE POWER FORECASTING / PREVISÃO DE POTÊNCIA REATIVA
No novo modelo do Setor Elétrico é essencial desenvolver novas técnicas que estimem valores futuros, a curto e longo-prazos, das potências ativa e reativa. Com base nisso, este trabalho tem por objetivo apresentar uma nova técnica de previsão horária de potência reativa a curto-prazo, por subestação, baseada na linearidade existente entre as potên

5. Projeto e implementação em VLSI de uma rede neural auto-organizavel usando sintese automatica de auto nivel
: A Kohonen-based (SOFM - Self-Organizing Feature Map ) artificial neural network was simulated, modelated and hardware implemented in a VLSI circuit. A Top-Down methodological approach was used by using ANSI-C and VHDL (Very High Speed Circuits, Hardware Description Language). The original SOFM algorithm was lightly modified for customizing to the hardware
