The research of Internet distribution of GIS contents is still in its infancy. This paper reports an implementation of a systematic approach to optimize Internet distribution of GIS datasets. The goal is to reduce user-perceived response time and improve users' navigation efficiency.On the server side, a large GIS dataset associated with a map is decomposed(More)
In the domain of computer security, how to enhance the speed of RSA algorithm has been the research hot spot. With the recent tremendous increase in Graphics Processing Unit's computing capability as a co-processor of the CPU, Nvidia’s Compute Unified Device Architecture (CUDA) can greatly benefit single instruction multiple thread styled,(More)
The classical inexact Newton algorithm is an efficient and popular technique for solving large sparse nonlinear system of equations. When the nonlinearities in the system are well-balanced, a near quadratic convergence is often observed, however, if some of the equations are much more nonlinear than the others in the system, the convergence is much slower.(More)
In this study, a new type of highly sensitive fiber-optic Fabry-Perot interferometer (FFPI) is proposed with a high sensitivity on a wide refractive index (RI) measurement range based on internal reflection mirrors of micro-cavity. The sensor head consists of a single-mode fiber (SMF) with an open micro-cavity. Since light reflections of gold thin films are(More)
