This paper presents a design and implementation of an intelligent testing system for checking the e-business application operation capable of the examinees. A novel architecture for on-line examination system is proposed. That system adopts the common client-server pattern with two major parts, the client component also called Student site and the application-oriented server component here also...

With the increasing capabilities of hardware for 3D graphics and network, 3D multi-user environments get more and more interesting for e-business, entertainment and cooperative work. This aspect concerns not only high-end devices, like caves or graphic workstation, also small mobile devices like laptop computers or PDAs become more and more suitable for the visualization of 3D graphics. In orde...

Business graphics are an important class of digital imagery. Such images are computer-generated, and comprise synthetic elements such as solid fills, line art, and color sweeps. Often these images are first printed and then scanned for further electronic reuse. The printing and scanning process destroys the synthetic structure of a graphics image, and furthermore introduces distortions due to h...

The occurrence of SH wave propagation under the effect of a point source in an orthotropic substratum lying over a heterogeneous orthotropic half space is deliberated in the prospect of a devastating earthquake. The quadratic alteration is acknowledged for density and shear modulus which is hypothesized to be a function of depth. The method of Green's function and transformation technique contr...
