1. D-VisionDraughts: uma rede neural jogadora de damas que aprende por reforço em um ambiente de computação distribuída
The objetive of this work is to propose a draughts learning system, the D-VisionDraughts (Distributed VisionDraughts): a distributed draughts player agent based on neural networks that learns by reinforcement. The D-VisionDraughts is trained in a distributed processing environment in order to achieve a high level of play without expert game analysis and with

3. Equações de biomassa e estoques de carbono de seis espécies em plantios mistos no noroeste do Mato Grosso
During this time of discussion about global warming and climate change, environmental restoration projects thought as a CO2 sink in its plant biomass are essential in the fighting the increasing concentration of global warming greenhouse gases. One very eficient method to sequester atmosphere carbon is through reforestation and quantifying the resulting stan

4. Cálculo de propriedades elétricas lineares, não-lineares e estruturais da molécula HOBr
Ab initio, also known as first principles, computational methods are highly esteemed because of the accuracy of the results produced and the fact that they are not built upon any empirical models, therefore considered reliable. Although, these positive remarks carry along a heavy computational effort, which increase very rapidly with the number of basis func

5. Regressão de dados binários : distribuição Weibull
In this work a new class of models for binary data based on Weibull distribution is introduced. A review is made of the most known linkage functions. This class of models has as special case the complementary log-log model and approximates well the logit and probit models. Three real data sets are given to compare the proposed model with many others. In one

6. Uma família de códigos corretores de erro para criptossistemas eficientes baseados em decodificação de síndromes. / A family of error-correcting codes to eficient cryptosystems based on syndrome decoding.
A criptografia é uma ciência que tem especial destaque no mundo moderno, evidenciando a necessidade em pesquisar algoritmos e técnicas para seu aperfeiçoamento. Apesar das soluções atualmente empregadas serem baseadas em problemas suficientemente seguros, se comparados ao poderio computacional necessário para resolvê-los, seu emprego futuro é questi

7. Nanofibres characterization through image processing techniques. / Caracterização de nanofibras através de técnicas de processamento de imagens.
The electrospinning technique represents a simple and convenient process to provide polymers and ceramics bers with both solid and hollow interiors that are exceptionally long in length, uniform in diameter, varying within the interval of few nanometers to several microns, and diversied in composition. Despite the versatility and potencially the scanning ele

8. Problema de reagrupamento capacitado / Redistricting capacitated problem
The aim of this dissertation is to develop an eficient methodology to solve the multicriteria redistricting capacitated problem (PACM), in which objects with associated weights are given, which must be partitioned into groups with limited capacity. In this work, the PACM is inserted in to a reassignment problem of urban clusters of clients, in which the read

9. Middleware Cerberus using RFID for traceability bovine / Middleware Cerberus usando RFID para rastreabilidade bovina
The management in zootechnics is increasingly necessary to ensure the profits and conquest of new markets that require a quality and certification. This monograph a traceability system is approached for the control in the bovinocultura using chips RFID. The identification holds of animals is the basic for trace cattle and buffaloes. Given the demands of the

10. Sistemas de análises químicas em fluxo explorando multi-impulsão, interface única ou quimiometria / Flow systems exploiting multi-pumping, single interface or chemometry
Multi-pumping flow systems (MPFS) present as an unique feature the use of solenoid pumps as fluid propelling devices, which deliver pulsed flows. This flow regime was evaluated in order to improve mixing conditions between the involved solutions, heating transfer and gas diffusion.The association of the chemometric methods of analysis and MPFS systems was de

11. Interações de peroxirredoxinas citossólicas da levedura Saccharomyces cerevisiae com peróxidos. Estudos cinéticos e funcionais / Saccharomyces cerevisiae cytosolic peroxiredoxin interactions with peroxides. Kinetics and functional studies
Peroxiredoxins constitute a family of cysteine-based peroxidases that are able to reduce hydrogen peroxide, organic peroxides and peroxinitrite to water, alcohol and nitrite, respectively, through the use of reducing equivalents provided by thioredoxin, thioredoxin reductase and NADPH. Peroxiredoxins are abundant enzymes (correspond to approximately 0.7% of

12. Development of areal time color classifier to robotics applications / Desenvolvimento de um sistema de classificação de cores em tempo real para aplicações robóticas
In computer vision, the detection of objects is a task of great importance. We can verify this by the existence of several methods proposed in the literature. Each one of these methods is based on some characteristics present in the image to reach an eficient performance. Considering environments that make use of colors for determining the objects present in
