The one-dimensional and two-dimensional sine-Gordon equations with dimensionless loss factors and unitless normalized bias are numerically calculated by computer. The results are presented for accelerations, velocities, collisions, coupled states, and two-dimensional propagation of solitons.

Abstract— Interest in the use of electrophoretic displays for smart handheld applications has grown tremendously over the past few years. Since the launch of the Philips and E Ink joint development effort in February 2001, material parameters, TFT backplane, electronic hardware and software and modulization skills have been developed to make this promising display concept into a real product. The first commercial launch of active‐matrix electronic‐ink display modules is planned for mid 2004.

Static and dynamic load balancing strategies for a multiprocessor system for a ray tracing algorithm based on constant subdivision are presented. An object space is divided into regular cubes (subspaces), whose boundary planes are perpendicular to the coordinate axes, and these are allocated to the processors in the system. Here, load balancing among the processors is the most important problem. Firstly, in a category of static load balancing, strategies for mapping the subspaces into the processors are evaluated by simulation. Moreover, we propose a hierarchical multiprocessor system in order to realize dynamic load balancing with the static one. Its architecture can overcome the limitation of the static load balancing in a large scale multiprocessor system.
