1. Why do Latin American firms hold so much more cash than they used to?
Resumo Este estudo avalia se as teorias de trade-off ou pecking order explicam o aumento dos índices de caixa em empresas latino-americanas. Ele também avalia o poder explicativo de variáveis adicionais que identificam características macroeconômicas fundamentais nas economias latino-americanas. Por causa de seu notável aumento, o caixa se tornou uma c

2. Etched FBG written in multimode fibers: sensing characteristics and applications in the liquid fuels sector
AbstractIn this work, a refractometric fiber sensor for the liquid fuels sector is described. The use of etched FBGs produced in multimode fibers is proposed to overcome the drawbacks associated with sensing high refractive index samples employing fiber transducers. The transducer sensitivity can be tailored by adjusting the final diameter of the etched Brag

3. A Multi-objective, active fuzzy force controller in control of flexible wiper system
Chaotic vibration has been identified in the flexible automotive wiper blade at certain wiping speeds. This irregular vibration not only decreases the wiping efficiency, but also degrades the driving comfort. A reliable nonlinear system identification namely nonlinear auto regressive exogenous Elman neural network (NARXENN) was adopted in first stage of this

4. Otimização na alocação dinâmica de veículos no transporte rodoviário de cargas completas entre terminais
The domain of logistics is concerned with providing customers with the right product in the right place at the right time. In our modern economy, the faster pace and wider scope of logistic operations has led to complex management problems that have drawn the attention of both industry and the academic world Optimizing the number of vehicles for a determined

5. Governança corporativa e a velocidade de ajuste da estrutura de capital das empresas brasileiras
O presente trabalho tem por objetivo analisar a relação entre governança corporativa e a velocidade de ajuste para a estrutura ótima de capital das empresas listadas na BM&FBovespa entre 1998 e 2009, sob o prisma da teoria do Trade-Off Dinâmico. O nível de governança corporativa foi medido com base nos segmentos de listagem diferenciada da BM&FBovespa

6. Country factors and the dynamic modeling of capital structure : an empirical study of latin american firms
Desenvolvemos modelos de ajuste parcial e de duration para testar a relevância de fatores específicos de países na determinação da estrutura de capital de empresas listadas nas bolsas de valores brasileira, chilena e mexicana. Utilizamos dados em painel, em um período que se estende do quarto trimestre de 1996 ao segundo trimestre de 2010, abrangendo 4

7. Estudo sobre a estrutura de capital das empresas brasileiras no período pós Plano Real (1995-2005)
The purpose of this work was to identify the determinants of the capital structure in Brazilian listed companies, from 1995-2005. After establishing the analytical framework, quantitative and qualitative procedures were used. From the quantitative point of view, the selected econometric technique was a balanced panel, additionally to the use of factor analys

8. A estrutura de capital das maiores empresas brasileiras: análise empírica usando Panel Data
Theories about capital structure suggest several variables that might determinate financing decisions. In general, the studies use cross-section or time series analysis to test these determinants. This study aimed to analyze some of the supposed determinants of capital structure of the larger Brazilian firms, under the lights of the two main theories, the Tr

9. Uma metodologia de projetos para circuitos com reconfiguração dinâmica de hardware aplicada a support vector machines. / A design methodology for circuits with dynamic reconfiguration of hardware applied to support vector machines.
Systems based on general-purpose processors are characterized by a flexibility to design changes, although with a computational performance below those based on optimized dedicated circuits. The implementation of algorithms in reconfigurable devices, known as Field Programmable Gate Arrays, FPGAs, offers a solution with a trade-off between the processors fle

10. Analise de suspensões veiculares utilizando tecnicas de controle robusto
This thesis presents an analysis of the H IND. 2 e H IND. INFINITO robust control theory via linear matrix inequalities, and an approach by Youla parametrization of the closed loop transfer matrix, applied to the design of three different vehicular suspension models. The focus is on comparative analyses of the techniques employed rather than on a specific pr

11. ONLINE TRAINING OF NEURAL METWORKS: METHODOLOGY FOR TIME VARYING ENVIRONMENTS / TREINAMENTO CONTÍNUO EM REDES NEURAIS: UM TRATAMENTO PARA AMBIENTES VARIANTES NO TEMPO
The main issue when dealing with non-stationary processes is related to the requirement of fast adaptation while simultaneously preventing catastrophic damage to previously learned behavior. In this thesis, two on-line learning techniques, one for supervised and the other for unsupervised artificial neural networks, are proposed. A new supervised procedure t

12. Dynamic flow alterations dictate leukocyte adhesion and response to endovascular interventions
Although arterial bifurcations are frequent sites for obstructive atherosclerotic lesions, the optimal approach to these lesions remains unresolved. Benchtop models of arterial bifurcations were analyzed for flow disturbances known to correlate with vascular disease. These models possess an adaptable geometry capable of simulating the course of arterial dise
