This paper studies a special instance of the graph partitioning problem motivated by an application in parallel processing. When a parallel computation is represented by a weighted task graph, we consider the problem of mapping each node in the graph to a processor in a linear array. We focus on a particular type of computation, a grid structured computation (GSC), where the task graph is a gri...

in this study, aluminum (al) matrix reinforced with micro-particles (30 µm) and nano-particles (50 nm) boron carbide (b4c) were used to prepare al-2.5%wt., b4c nano-composite and micro-composite, respectively, using mechanical alloying method. the mixed powders were mechanically milled at 5, 10, 15 and 20 hrs. the xrd results indicated that the crystallite sizes of both the micro-composite and ...

Most events are processed by a number of neural pathways. These pathways often differ considerably in processing speed. Thus, coherent perception requires some form of synchronization mechanism. Moreover, this mechanism must be flexible, because neural processing speed changes over the life of an organism. Here we provide behavioral evidence that humans can adapt to a new intersensory temporal ...

Land-use changes result from in the human population, their activities, and social environmental which occur a complex dynamic manner. The change of forested areas to non-forested areas, also known as deforestation, is land-use change. Deforestation influences land cover by creating specific distribution pattern (fragmentation). Almost entire forest has been fragmented into smaller but each the...

We introduce the Schlesinger transformations for Gambier, linearisable, equation and by combining former construct contiguity relations of solutions latter. extend approach to discrete domain obtaining thus Gambier mapping. In all cases resulting relation is a linearisable equation, involving free functions, which can be related generic

Cultured aortic endothelial cells, like their in vivo counterparts, form highly organized, confluent monolayers of polarized epithelioid cells that secrete, exclusively at their basal surface, an extracellular matrix to which they then attach. The influence of isolated subendothelial matrix preparations on cell polarity and monolayer organization was studied by presenting fragments of the matri...
