A computational method based on Chebyshev series to rigorously compute solutions of initial and boundary value problems of analytic nonlinear vector fields is proposed. The idea is to recast solutions as fixed points of an operator defined on a Banach space of rapidly decaying Chebyshev coefficients and to use the so-called radii polynomials to show the existence of a unique fixed point nearby ...

introduction: voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, alzheimer's disease and parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). the aim of this study is evaluate the effectiveness of this method in detection of dif...

This article describes work carried out to investigate whether a classic reaction-diffusion (RD) system could be used to control a minimally cognitive animat. The RD system chosen was that first described by Gray and Scott, and the minimally cognitive behaviors were those used by Beer et al. involving the fixation and discrimination of diamond and circle shapes by a whiskered animat. A further ...

Self-esteem remains a popular research topic especially as it pertains to African American2 communities. Blacks were commonly understood to possess low selfesteem and, as a consequence, to suffer from a host of intra-psychic and interpersonal problems (Banks, 1976; Clark & Clark, 1950; Cross, 1991; Horowitz, 1939; Hoelter, 1982; Lind, 1914; Scott, 1997). More recent findings have documented tha...

With no vaccine or medicine specifically designed to treat Dengue, attention naturally shifts to prevention. Minimizing the risk of the disease equates to minimizing the exposure to aedes aegypti. Getis, Morrison, Gray, and Scott conducted a spatial study of the distribution of the aedes aegypti in Iquitos, Peru, a city of about 345,000 people 120m above sea level in the Amazon basin area of Pe...

We introduce a model of the second-order lambda calculus. Such a model is a Scott domain whose elements are themselves Scott domains, and in it polymorphic maps are interpreted by generic continous maps.

in this paper a simple and effective expert system to predict random data fluctuation in short-term period is established. evaluation process includes introducing fourier series, markov chain model prediction and comparison (gray) combined with the model prediction gray- fourier- markov that the mixed results, to create an expert system predicted with artificial intelligence, made this model to...

Let X be a dcpo and let L be a complete lattice. The family σL(X) of all Scott continuous mappings from X to L is a complete lattice under pointwise order, we call it the L-fuzzy Scott structure on X. Let E be a dcpo. A mapping g : σL(E) −> M is called an LM-fuzzy possibility valuation of E if it preserves arbitrary unions. Denote by πLM(E) the set of all LM-fuzzy possibility valuations of E. T...
