The National Cultural Congress which was held in 1971 has brought the idea of national identity into art and served as a guideline for Malaysian artists their creative process. In this context, Islam becomes one main elements representing our cultural identity. As result, Islamic patterns serve symbols styles that were applied most contemporary Malaysia to interpret connections between man, uni...

Pattern formation in physiochemical systems through the interaction of spatial diffusion and the local properties of the chemical reactions involved has been the subject of active research in recent years (Gmitro and Scriven 1966, Nicolis and Prigogine 1977, Winfree 1980). While the role of diffusion in such a synthesis is open to debate (Thones 1973), the reaction-diffusion (R-D) hypothesis ha...

This paper investigates the global synchronization method of two identical systems and two different chaotic systems. The proposed method is effective and convenient to synchronize two identical systems and two different chaotic systems by using nonlinear control functions. The method has been applied successfully to make two identical four-scroll attractor and also two different chaotic system...

We describe a novel nucleation mechanism of scroll rings in three-dimensional reaction-diffusion systems with anomalous dispersion. The vortices form after the collision of two spherical wave fronts from a third, trailing wave that only partially annihilates in the wake of its predecessor. Depending on the relative positions of the three relevant wave sources, one obtains untwisted or twisted s...

Anchoring of spiral and scroll waves in excitable media has attracted considerable interest in the context of cardiac arrhythmias. Here, by bombarding inclusions with drifting spiral and scroll waves, we explore the forces exerted by inclusions onto an approaching spiral and derive the equations of motion governing spiral dynamics in the vicinity of inclusion. We demonstrate that these forces n...
