The Problem: The simulated evolution of virtual creatures has produced many intriguing demonstrations, providing simple locomotion abilities and strategies for simple competetive games. However, to achieve a richer set of behaviours, adaptation within the individual’s lifetime is being explored. Can evolution be used to learn domain specific rules for solving the credit assignment problem and s...

Evidence has shown that racial-ethnic minorities in the U.S. are less likely than whites to engage in leisure-time physical activity (LTPA); yet few studies to date have included Asian subgroups in the analyses and mechanisms underlying these disparities are not well-known. This study uses data from the 2007 California Health Interview Survey (N=37,164) to examine racial-ethnic disparities in s...

The feature map represented by the set of weight vectors of the basic SOM (Self-Organizing Map) provides a good approximation to the input space from which the sample vectors come. But the timedecreasing learning rate and neighborhood function of the basic SOM algorithm reduce its capability to adapt weights for a varied environment. In dealing with non-stationary input distributions and changi...

Lifetime exposures to adverse social environments influence adult health, as do exposures in early life. It is usual to examine the influences of school on teenage health and of adult area of residence on adult health. We examined the combined long-term association of the school attended, as well as the area of residence in childhood, with adult health. A total of 6,285 children from Aberdeen, ...

PURPOSE Studies have demonstrated the effects of segregated social and physical environments on the development of chronic diseases for African Americans. Studies have not delineated the effects of segregated environments specifically on the health of African American men over their lifetime. This study examines the relationship between life course measures of racial composition of social envir...

Let $L$ be an integral and commutative quantale. In this paper, by fuzzifying the notion of generalized neighborhood systems, the notion of $L$-fuzzy generalized neighborhoodsystem is introduced and then a pair of lower and upperapproximation operators based on it are defined and discussed. It is proved that these approximation operators include generalized neighborhood system...

Wireless Sensor Network is becoming a very important area of research in today’s world and contributes lot the field technology. Reducing energy consumption improving network lifetime key factor to be considered. Clustering provides an effective way for prolonging wireless sensor network. Current clustering algorithms usually utilize two techniques, selecting cluster heads with more residual ro...

nowadays, wireless sensor network has been of interest to investigators and the greatest challenge in this part is the limited energy of sensors. sensors usually are in the harsh environments and transit in these environments is hard and impossible and moreover the nodes use non- replaceable batteries. because of this, saving energy is very important. in this paper we tried to decrease hard and...

For two graphs $mathrm{G}$ and $mathrm{H}$ with $n$ and $m$ vertices, the corona $mathrm{G}circmathrm{H}$ of $mathrm{G}$ and $mathrm{H}$ is the graph obtained by taking one copy of $mathrm{G}$ and $n$ copies of $mathrm{H}$ and then joining the $i^{th}$ vertex of $mathrm{G}$ to every vertex in the $i^{th}$ copy of $mathrm{H}$. The neighborhood corona $mathrm{G}starmathrm{H}$ of $mathrm{G}$ and $...
