grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. mobile computing is a generic word that introduces using of movable, handheld devices with wireless communication, for processing data. mobile computing focused on providing access to data, information, services and communications anywhere an...

objective: the aim of this study was to measure and compare the transverse strength and deflection of two acrylic resins. method and materials: a total of 30 samples, with dimensions of 2.5×10×65mm, were prepared with acropars and meliodent acrylic resins according to ada specification no. 12. the specimens were divided into two groups of 15 samples each. a three-point bending test was carried ...

A common question about U.S. Geological Survey (USGS) digital raster graphics (DRG) is “how can I remove the map collars and join multiple quadrangles together?” The question does not have a simple answer because of the characteristics of USGS quadrangles. Quadrangle neatlines are defined by lines of latitude and longitude, so quadrangles are not rectangles on their published projections. But d...

to use services transparently in a distributed environment, the utility grids develop a cyber-infrastructure. the parameters of the quality of service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the utility grids. optimization of both target parameters above is a challenge in a distributed environment and may conflict one ano...

abstract the usage of heroin is associated with a variety of neurologic disorders, including acute transverse myelitis. in this study we present a 19 year old man who was suffered from insufflated heroin after several months of abstinence, and admitted to hospital emergency department, unconscious. he responded to fluid therapy and naloxone, but could not move his legs on examination. he had fl...

This paper presents the results of the analysis of 56,000 flat grids in a form suitable for minimum weight design.

An overview is given of finite volume central schemes for the numerical solution of systems of conservation and balance laws. Well balanced central schemes on staggered grid for the Saint-Venant model or river flow are considered. A scheme which is well balanced for channels with variable cross section is introduced. Finally, a scheme which preserves non static equilibria is introduced, and som...

The 2D transverse electric (TE) Maxwell equations have been solved by a Finite Volume method. The reconstruction of quantities on the cell interfaces is taken as an average of the values in the two neighbouring cells. We use an explicit three step Runge-Kutta method for the time-stepping. This method is well suited for a SIMD machine because of the locality of references. We run our code on a 1...
