Any modern Graphics Processing Unit (graphics card) is a good platform to run massively parallel programs. Still, we lack tools observe and measure performance characteristics of GPU-based software. We state that due complex memory hierarchy thou- sands execution threads the all issues are about efficient use graphics card hierarchy. propose GPGPUSim simulator, previously used mostly for archit...

Particle tracking simulations with space charge effects are very important for high-intensity proton rings. Since they include not only Hamilton mechanics of a single particle but constructing densities and solving Poisson equations to obtain the electromagnetic field due charge, extremely time-consuming. We have newly developed simulation code that can be used in Graphics Processing Units (GPU...

To manipulate and modify digital images are very easy due to rapid advances of image processing software. So, to judge the authenticity of a given image is very difficult for a viewer. Many documents are created by Cut-And-Paste (CAP) of existing documents. In this thesis, we proposed a novel technique to detect CAP in document images using Neural Network. This can help in detecting unethical C...

A brief survey on on-line graphics recognition is presented. We first present some common scenarios and applications of on-line graphics recognition and then identify major problems and sub-problems at three levels: primitive shape recognition, composite graphic object recognition, and document recognition and understanding. Representative approaches to these problems are also presented. We als...

Zed3D is a document about computer graphics, more particularly real-time 3d graphics. This document should be viewed as a practical reference for a first and perhaps second course in computer graphics. The original Zed3D document grew out of my work notes. As a matter of fact, the original Zed3D, up to version 0.61beta, was my work notes. As such, it was messy, incomplete and often incorrect. I...
