Economists look at the entrepreneurship from the prospective of profitability, investment, risk, and insight supporting the economical development but it seems that, in modern societies, entrepreneurship`s function is beyond the economical bounds. According to the stage and importance of entrepreneurship which is known as the society’s economic and culture evolution engine, it is necessary to d...

This article is devoted to economical aspects of Human Computation (HC) and to perspectives of HC in economics. As of economical aspects of HC, it is first observed that much of what makes HC systems effective is economical in nature suggesting that complexity being reconsidered as a “HC complexity” and the conception of efficient HC systems as a “HC economics”. This article also points to the ...

The economical and secure operation of power systems has significant importance. Due to technical limitations, the best economical operation point is not always the desired operating point for system stability or power losses. In this study, first, the most economical operating point is obtained by solving the nonlinear, network-constrained economic dispatch problem using a genetic algorithm. T...

the both atlantic side relations from the ancient time had been faced with too much challenge but the continuing of this relation is due to the common political and economical interests. the upper atlantic and the two organizations (nato, eu) still exist to gain the essential goals and the political and security connection which are boosting with the economical integration at the same time. but...

Caves and rockshelters are found all over the world, and they have been frequently occupied throughout prehistory and early history. In many areas of Europe, some of these natural places are still used as sites of worship and as shelter against the elements. There is great variability in their use. Some appear to only have traces of short occupations, while others have thick cultural deposits, ...

A number n is said to be economical if the prime power factori-sation of n can be written with no more digits than n itself. We show that under a plausible hypothesis, related to the twin prime conjecture, there are arbitrarily long sequences of consecutive economial numbers, and exhibit such a sequence of length 9.

Linkage maps allow us to deepen the understanding of the genome of a species and the identification of genes or genomic regions, denominated QTL, which control traits of economical importance. The phenotypic expression of these genes can have a discrete or continuous distribution; in the latter case the trait is generally controlled by more than one gene. Among the markers applied for mapping t...
