25. Identification and agreement of first turn point by mathematical analysis applied to heart rate, carbon dioxide output and electromyography
BACKGROUND: The second heart rate (HR) turn point has been extensively studied, however there are few studies determining the first HR turn point. Also, the use of mathematical and statistical models for determining changes in dynamic characteristics of physiological variables during an incremental cardiopulmonary test has been suggested. OBJECTIVES: To

26. Analytical and Mathematical Modeling and Optimization of Fiber Metal Laminates (FMLs) subjected to low-velocity impact via combined response surface regression and zero-One programming
This paper presents analytical and mathematical modeling and optimization of the dynamic behavior of the fiber metal laminates (FMLs) subjected to low-velocity impact. The deflection to thickness (w/h) ratio has been identified through the governing equations of the plate that are solved using the first-order shear deformation theory as well as the Fourier s

27. Desenvolvimento de ferramenta de comparação de técnicas de processamento de sinais para determinar fadiga muscular por meio do sinal emg / Toolkit development for signals processing technics comparison to detect muscular fadigue by EMG signal
This study aimed to development of a computational tool for electromyographic signal (EMG) analysis by signal processing techniques to determine muscular fatigue. With Ethics Committee of Federal University of Goiás approve were recorded from the dominant biceps brachii of 10 volunteers, that did not ever had muscular disease. The protocol consisted on get

28. Relação dinâmica entre a estrutura de propriedade e controle e o valor de mercado corporativo no Brasil: análise da primeira década do século XXI / Dynamic relationship between ownership and control structure and corporate market value in Brazil: Analysis of first decade of XXI century
The Brazilian model of corporate governance is characterized by the ownership and control concentration of most publicly traded companies. In this context, the academic literature points to the existence of a positive and a negative impacts of this shares accumulation by controller (s) on corporate performance, known respectively as incentive effect (or alig

29. Variabilidade climática e correlação entre TSM e vazão fluvial nos rios Amazonas e Negro / Climate variability of the Atlantic and Pacific oceans and flow of the rivers Amazonas and Negro
Climate variability is a complex system generated by the participation of various actors and their role in atmospheric dynamics, the Sea Surface Temperature(SST) plays a key role in influencing the several features of the climate indexes: Southern Hemisphere Cancel Index Mode (SAM), Southern Oscillation Index (SOI), El Nino / Southern Oscillation (ENSO), (TN

30. Ensaios não destrutivos aplicados à madeira serrada e estruturas : técnicas potenciais para uso no Brasil
The wood has many different characteristics, resulting, in part, of the conditions in which the tree grows. The physical conditions of the wood are also influenced by its complex internal structure, resulting in an anisotropic behavior. Within this variability, its best use and application can be reached through non-destructive methods. The non-destructive m

31. FORECASTING OF JUDICIAL CONTINGENCY IN ELECTRIC SECTOR COMPANIES: AN APPROACH VIA DYNAMIC REGRESSION AND EXPONENTIAL SMOOTHING / PREVISÃO DE CONTINGÊNCIA JUDICIAL EM EMPRESAS DO SETOR ELÉTRICO: UMA ABORDAGEM VIA REGRESSÃO DINÂMICA E AMORTECIMENTO EXPONENCIAL
The aim of this dissertation is to develop short term models to forecast the number of judicial process in electric sector companies. From the methodology point of view, data is analyzed and models using bottom-up strategy is developed. In other words, a simple model is improved step by step until a proper model that fits well the reality is found. From a un

34. Melhoramento de plantas: progresso genético e ambiental.
ABSTRACT: The plant breeding plays basic role in the attainment of suitable and superior genotypes to be used for farmers. The estimates of the genetic and environmental progress reached by the breeding programs are important to quantify the efficiency of the executed works and to define new strategies of breeding programs. Some techniques had been developed

36. Determinantes da taxa de juros no Brasil: uma abordagem não-linear
This paper investigates the interest rate determination in Brazil based on autoregressive Markov-Switching Process (MS-VAR). Initially developed to model US business cycle, the MS-VAR approach has been used in several fields in conomics due to its flexibility and to its important empirical results, based on estimates of nonlinear parameters of the regression
