Collision-free motion among dynamic moving objects is an on-going research topic. Based on the concept of modified path-velocity decomposition, a strategy, the interface propagation method, is proposed for path planning in this paper. Since all global navigation paths are assumed to be planned already without any static obstacle in their paths. Each sub-task along the global path of each contro...

Nowadays, house packaging waste (HPW) materials acquired a great deal of importance, due to environmental and economic reasons, and therefore waste collection companies place thousands of collection points (ecopontos) for people to deposit their HPW. In order to optimize HPW collection process, accurate forecasts of the waste generation rates are needed. Our objective is to develop forecasting ...

in the deregulated power systems, transmission congestion is one of the significant and main problems of the electrical networks which can cause incremental cost in the energy. this problem has resulted to new challenging issues in different parts of power systems which there was not in the traditional systems or at least had very little importance. transmission congestion happens when the maxi...

Case 1. A full-term male child, weighing 6j lb., the product of a second pregnancy, was born on Aug. 3, 1945. The parents were unrelated. When three months old the child was thought to be blind, and two months later on x-ray examination a diagnosis of osteopetrosis was made. Mental retardation was noted at ten months. At two years two months he was admitted to the Royal Blind School; he was a w...

The specific feature of the Overlapping Generations Model is that new cohorts are born in every period, live for a number of periods and die. Consequently, at any point in time, society is composed of individuals belonging to the different generations that are currently alive. Because of the demographic structure of the population, no trade involving individuals about to die is possible and hen...

The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in...

Intel’s processor clock has tocked, delivering a nextgeneration architecture for PCs and servers. At the recent Intel Developer’s Forum (IDF), the company unveiled its Sandy Bridge processor architecture, the next tock in its tick-tock roadmap. The new CPU is an evolutionary improvement over its predecessor, Nehalem, tweaking the branch predictor, register renaming, and instruction decoding. Th...

■ Abstract Naturally occurring variations in maternal care alter the expression of genes that regulate behavioral and endocrine responses to stress, as well as hippocampal synaptic development. These effects form the basis for the development of stable, individual differences in stress reactivity and certain forms of cognition. Maternal care also influences the maternal behavior of female offsp...
