Melanocytic nevi are recognized as precursors of melanoma. Aiding in early recognition of melanoma, we estimated color texture parameters, fractal dimension and lacunarity of melanoma and other melanocytic nevi. Digital images of the lesions were processed. Graphic three-dimensional pseudoelevation images of the lesions and surrounding skin were produced to identify irregularities in color text...

We introduce a new measure for the capital market efficiency. The measure takes into consideration the correlation structure of the returns (long-term and short-term memory) and local herding behavior (fractal dimension). The efficiency measure is taken as a distance from an ideal efficient market situation. Methodology is applied to a portfolio of 41 stock indices. We find that the Japanese NI...

In this paper we offer a way to measure the knowledge base of an economy in terms of probabilistic entropy. This measure, we hypothesize, is an indication of the extent to which a system, including the economic system, self-organizes. In a self-organizing system, interactions between dimensions or subsystems will unintentionally give rise to anticipations that are properly aligned. The potentia...

let r be a commutative noetherian ring. we study the behavior of injectiveand at dimension of r-modules under the functors homr(-,-) and -×r-.

Due to the increasingly demand for spatio-temporal analysis, time series and spatial statistics are extended to the spatial dimension and the temporal dimension respectively or they are combined via linear regression. However, such linear regression is just a simplification of complicated spatio-temporal associations existing in complex geographical phenomena. In this study, the Support Vector ...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a rm can costlessly receive external knowledge best. Since knowledge spillovers are unmeasurable, a `goodness of t' measure is constructed using innovation survey data. It turns out that measures of the uncentered correla...

This article addresses the perceptual identification of French regional accents by listeners from the Paris region and Belgium. It is based on the geographical localisation of about thirty speakers from seven French-speaking areas: Vendee (West of France), Languedoc (South of France), Alsace (East of France), Romand Switzerland, East, Centre and West of Belgium. Contrary to the speake bracket (...

Most research on family interventions of children with autism has focused on the role of the mother, and little is known about the effects of training fathers. Through a series of National Institutes of Health– funded studies we have demonstrated treatment success by focusing on fathers who are trained at home. Although our research has been successful, this work introduces questions related to...

Since at least the sixteenth century, the areas of the present day regions of Harar and Wallo have been important centres of teaching and diffusion of Islam as well as of preservation of Islamic culture and education. Preachers and scholars from these areas played a decisive role in the introduction and dissemination of the faith in the country, especially in the eighteenth and nineteenth centu...
