1. Rheology of mine tailings deposits for dam break analyses
Abstract This article deals with the rheology of tailings deposits related to dam break analysis. The material used was a fine tailings from iron ore processing. Geotechnical and rheological characterization of these tailings were performed. The rheological characterization consisted of rotational and oscillatory tests. It was observed that the rheological p

2. Macrodinâmica à Keynesiana : uma travessia com consistência entre fluxos e estoques a partir do encadeamento de curtos períodos do multiplicador / Keynesian-style macrodinamics : a stock-flow consistent traverse throught the enchainment of short multiplier periods
This thesis is divided into three parts. The first one discusses the short period behind the traditional autonomous expenditure multiplier, in a way that exposes the major macroeconomic aggregates and their interconnections; at this point the separation between the autonomous and induced parcels with respect to income is crucial. A second chapter, compoundin

3. Designing a neural network for closed thermosyphon with nanofluid using a genetic algorithm
Heat transfer of a silver/water nanofluid in a two-phase closed thermosyphon that is thermally enhanced by magnetic field has been predicted by an optimized artificial Neural Network. Artificial neural network is a technique with flexible mathematical structure that is capable of identifying complex non-linear relationships between input and output data. A m

4. A geometrical approach for fuzzy DEA frontiers.
Interval DEA frontiers are here used in situation where one input or output is subject to uncertainty in its measurement and is presented as an interval data. We built an efficient frontier without any assumption about the probability distribution function of the imprecise variable. We take into account only the minimum and the maximum values of each impreci

5. Sugarcane crop efficiency in two growing seasons in São Paulo State, Brazil.
A conceptual framework for crop production efficiency was derived using thermodynamic efficiency concept, in order to generate a tool for performance evaluation of agricultural systems and to quantify the interference of determining factors on this performance. In Thermodynamics, efficiency is the ratio between the output and input of energy. To establish th

6. A indústria moveleira de Boa Vista : estrutura e potencialidades
O objetivo desta dissertação foi avaliar a estrutura e as potencialidades da indústria moveleira do Município de Boa Vista (Roraima). Para a obtenção dos dados, foram aplicados questionários a empresas filiadas ao Sindicato das Indústrias de Marcenaria do Estado de Roraima – SINDIMAR; de um total de 19 empresas, 15 responderam aos questionários, r

7. Um estudo sobre métodos de Kernel para classificação e agrupamento de dados
The learning machines project involves modelling a set of samples based on the mapping performance of the input-output pairs. The group of samples submitted to training provides information for determining the parameters of the model. And the validation and/or test group evaluates the performance of the classifier on its generalization ability. However, the

8. "Planejamento de quinonas com atividade tripanossomicida" / Planning of quinone compounds with trypanocidal activity
A set of 25 quinone compounds with anti-trypanocidal activity was studied by using the Density Functional Theory (DFT) method in order to calculate electronic atomic and molecular properties to be correlated with the biological activity. The chemometric methods Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), Stepwise Discriminant Ana

9. Non linear signal analysis applied to friction force identification in tribological tests / Identificação da força de atrito através de análise de sinais não lineares em ensaios tribológicos
When the surfaces of two elastic bodies present relative motions under certain amount of contact pressure the mechanical system can be instable. Experiments conducted on elastic bodies under friction forces shown that the dynamical system is self-excited by the non-linear behavior of frictional forces. The main objectives of this thesis are the study of the

10. Intersectorial relationships of the acrean economy and its insertion into the brazilian economy: an input-output analysis. / Relações intersetoriais da economia acreana e sua inserção na economia brasileira: uma análise insumo-produto.
Este estudo aplicou os princípios da teoria insumo-produto para analisar a importância relativa dos setores primários e, em especial, do setor florestal para a economia acreana, bem como a sua dependência com relação às regiões resto do Norte e resto do Brasil. Os resultados decorrentes desta análise também permitiram caracterizar a estrutura produ

11. Fitomonitoração e modelagem de fotossíntese em jatobá (Hymenaea courbaril L.) com redes neurais artificiais. / Phytomonitoring and modelling of photosynthesis in jatobá (Hymenaea courbaril L.) with artificial neural.
The increases in greenhouse gas concentrations, mainly carbon dioxide, and the climatic changes have become important scientific, economic, and political subjects in the past years. The Kyoto Protocol establishes the Clean Development Mechanism, which grants carbon credits for projects that promote the sequestration of carbon in developing countries. Therefo

12. Analise e previsões de vasões utilizando modelos de series temporais, redes neurais e redes neurais nebulosas
Analysis and forecast of seasonal stream flow series are of utmost importance in the operation planning of water resources systems. One of the greatest difficulties in forecasting of those series is the seasonality nature of stream flow series due to wet and dry periods of the year. For a long time, the use of stochastic models, based on the c1assic Box &Jen
