1. The Long-Range Memory and the Fractal Dimension: a Case Study for Alcântara
ABSTRACT: This study aimed to analyze the time series behavior of the Southern Oscillation Index through techniques using Fast Fourier Transform, computing the autocorrelation function, and the calculation of the Hurst coefficient. The methodology of Hurst Exponent calculation uses different lags, which are computed in the time series of Southern Oscillation

2. Softening Mechanisms of the AISI 410 Martensitic Stainless Steel Under Hot Torsion Simulation
This study investigated the softening mechanisms of the AISI 410 martensitic stainless steel during torsion simulation under isothermal continuous in the temperature range of 900 to 1150 °C and strain rates of 0.1 to 5.0s-1. In the first part of the curves, before the peak, the results show that the critical (εc) and peak (εp) strains are elevated for hig

3. Análisis de tasas y modelos para generación de viajes en hipermercados y supermercados
The location of commercial trip generation hubs produces urban impacts in the area of influence since they increase the number of vehicle trips that affects environment and quality of life. For better understanding of this phenomenon, it is reported in this article an analysis of trip generation rates and models in hypermarkets and supermarkets considering d

4. Transporte elétrico e magnetotransporte em carbono granular
In this work we have studied the electrical conduction between localized states in samples with dierent volumetric densities of carbon-black, a kind of granular carbon. Firstly, we have shown that the Mott s variable range hopping (VRH) model t our data in a large range of temperatures. At low temperatures, we can see a deviation to a larger exponent, which

5. Um estudo sobre a minimização de funcionais de expoente variável aplicados à restauração de imagens digitais / An study over the minimization of functionals of exponent variable applied to the restauration from digital images
Estuda-se neste trabalho um funcional com expoente variável, ou seja, com 1 ≤ p(x) ≤ 2, o qual fornece um modelo para a restauração de imagens digitais, mais precisamente para a remoção de ruídos. A difusão resultante do modelo proposto é uma combinação da Variação Total com a difusão isotrópica. A existência, unicidade e o comport

6. SimulaÃÃo de fluidos imiscÃveis em meios porosos atravÃs de autÃmatos celulares de gÃs na rede
In this study, we investigated the displacement of two immiscible fluids in bidimensional porous media by means of models of lattice gas cellular automata. Such an automaton can reproduce the behavior of the Navier-Stokes equation, along with the Laplace equation for the case of two immiscible fluids and, besides, can implement conditions of complex contour

7. Variable survival exponents in history-dependent random walks: hard movable reflector
We review recent studies demonstrating a nonuniversal (continuously variable) survival exponent for history-dependent random walks, and analyze a new example, the hard movable partial reflector. These processes serve as simplified models of infection in a medium with a history-dependent susceptibility, and for spreading in systems with an infinite number of

8. PartsList: a web-based system for dynamically ranking protein folds based on disparate attributes, including whole-genome expression and interaction information
As the number of protein folds is quite limited, a mode of analysis that will be increasingly common in the future, especially with the advent of structural genomics, is to survey and re-survey the finite parts list of folds from an expanding number of perspectives. We have developed a new resource, called PartsList, that lets one dynamically perform th
