We examine a diffusive, incompressible three component mixing system with symmetric, degenerate equilibrium values of the free energy. To the best of our knowledge, this presents the first example of a realization of a phase ordering system with a conserved two component vector order parameter. We present and discuss the dynamics of our system in one, two, and three dimensional systems using th...

We consider a lattice model for three-component systems in which the lattice bonds are covered by molecules of type AA, BB, and AB, and the only interactions are between the molecular ends of a common lattice site. The model is equivalent to the standard Ising model, and the coexistence curves for different lattices and/or some specific form of the interactions have been previously investigated...

In this paper, we introduce a three-component Schnakenberg model. Its key feature is that it has solution consisting of N spikes undergoes Hopf bifurcation with respect to distinct modes nearly simultaneously. This results in complex oscillatory dynamics the spikes, not seen typical two-component models. For parameter values above bifurcations, derive reduced equations motion which consist coup...

In this article, we analyze the stability and the associated bifurcations of several types of pulse solutions in a singularly perturbed three-component reaction–diffusion equation that has its origin as a model for gas discharge dynamics. Due to the richness and complexity of the dynamics generated by this model, it has in recent years become a paradigm model for the study of pulse interactions...

We have developed NetPay, a micro-payment protocol characterized by off-line processing, customer anonymity and relatively high performance and security using one-way hashing functions for encryption. In our NetPay prototypes we have designed and implemented two kinds of NetPay vendor systems which use thin-client user interfaces, a component-based server-side infrastructure and CORBA remote ob...

In this article, we analyze the three-component reaction-diffusion system originally developed by Schenk et al. (PRL 78:3781–3784, 1997). The system consists of bistable activator-inhibitor equations with an additional inhibitor that diffuses more rapidly than the standard inhibitor (or recovery variable). It has been used by several authors as a prototype three-component system that generates ...

spleen is a major component of the reticuloendothelial system and functions as a filtering system for the encapsulated bacteria especially in children. knowing the spectrum of conditions leading to splenectomy in any geographic area is important to decrease the number of unnessesary splenectomies. here we report the causes of splenectomy in three major general referring hospitals in shiraz, the...

The available fatigue theories have been examined using simple specimens subjected to bending or tension-compression loads. Therefore, the stress fields have been generally one or two dimensional. Anti-roll bar is a component belongs to the suspension system of the vehicles. In spite of having simple circular section, due to the having several curvatures, this component experiences a three-dime...
