The Method of Moments (MoM) technique is the backbone of all computational methods for the modeling and simulation of complex systems. With applications including fluid mechanics, electromagnetics, and fracture modeling, MoM is versatile and has laid the foundation for modern optimization methods. Modeling and simulation is absolutely necessary for the success of all complex engineering problems of...
The quest for raw computing power has shifted from increasing processor clock speeds to increasing the number of processing cores. Currently, mainstream CPUs can be purchased in dual-slot quad-core and hex-core configurations. On the other hand, graphic cards provide hundreds of processing cores. Although there have been various implementations of scientific applications on graphics hardware, including...
The main purpose of this paper is to demonstrate how we make use of the powerful graphics processor, NVIDIA GTX280, in numerical simulation with the support of double precision floating number. Apply the finite volume method in simulating the Euler equation, two well-known examples for travelling shock waves were examined in high resolution. We had achieved at best 878 times faster than a Core 2 Duo...
We present a method for fast phase based registration of volume data for medical applications. As the number of different modalities within medical imaging increases, it becomes more and more important with registration that works for a mixture of modalities. For these applications the phase based registration approach has proven to be superior. Today there seem to be two kinds of groups that work...
Main objective of this paper is to outline possible ways how to achieve a substantial acceleration in case of advection-diffusion equation (A-DE) calculation, which is commonly used for a description of the pollutant behavior in atmosphere. A-DE is a land of partial differential equation (PDE) and in general case it is usually solved by numerical integration due to its high complexity. These types...
