The efficiency of a multicomputer is critically dependent on the performance of its interconnection network. This paper presents a new analytical model for circuit-switched cubic networks in the presence of correlated traffic pattern, which is a typical scenario for multimedia applications. A message in circuit switching may need a number of connection attempts before successfully setting up a ...

It is a challenge to simulate the switching process of functional self-assembled monolayers (SAMs) on metal surfaces, since the systems consist of thousands of atoms and the switching is triggered by quantum-mechanical events. Herein a molecular dynamics simulation with a reactive rotation potential of N=N bond is implemented to investigate the dynamic conformational changes and packing effects...

In this paper we present a cross-cutting design principle for binary decision control (BDC) based congestion control systems, such as AIMD. Due to its discontinuity, constructing the switching function, or the onset condition of the congestion bit, must consider the relative degree and zero dynamics of the system based on sliding mode control (SMC) theory. We showed that the relative degree of ...

The burst contention problem in Optical Burst Switching network is an intrinsically serious problem. Many researches have tried to solve this problem, however it have been known that avoiding the burst loss is very difficult issues in the current OBS network. To improve burst blocking rate, we consider the edge/core combined OBS network where the core node performs the edge node function as wel...

Potential energy surfaces of N,N-hydrogen migration of pyrazole and 5-methyl pyrazole for the ground and triplet states were calculated by the ab initio molecular orbital methods. All potential energy surfaces for the N.N-hydrogen shift have high energy barriers. The occurrence of the structural change indispensable to the switching function is doubtful for pyrazole and 5-methyl pyrazole. The s...

In this paper, a nonlinear control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear control strategy is developed that stabilizes a given nonlinear system by stabilizing a collection of nonlinear controlled...

Abstract: In this paper, we study the synchronization problem for complex dynamical networks with switching topology. The synchronization problem is transformed into the stability problem for a time-varying switched system. We address two basic problems: synchronization under arbitrary switching topology, and synchronization via design of switching within a pre-given collection of topologies wh...

Switched systems are often described by continuous and discrete dynamics as well as their interactions. Although results are available for linear switching systems, for nonlinear switching models few results exist. In this chapter, we consider observer design for discrete-time switching nonlinear systems with a Takagi– Sugeno representation. For designing the observers, a switching nonquadratic...
