Networks whose structure of connections evolves in time constitute a big challenge in the study of synchronization, in particular when the time scales for the evolution of the graph topology are comparable with (or even longer than) those pertinent to the units' dynamics. We here focus on networks with a slow-switching structure, and show that the necessary conditions for synchronization, i.e. ...
The switching speeds of electronics cannot keep up with the transmission capacity offered by optics. All-optical switch fabrics play a central role in the effort to migrate the switching functions to the optical layer. Optical packet switching provides an almost arbitrary fine granularity but faces significant challenges in the processing and buffering of bits at high speeds. Generalized multip...
Recent research in switching has concentrated on various forms of statistical switching networks capa ble of supporting user connections of arbitrary band width Fast packet switching is one approach that has gained a lot of attention and is being studied by many researchers This paper addresses the problem of how the con guration of user connections a ects the loading of the internal links of a...
This paper presents accurate estimation of signal activity at the internal nodes of CMOS combinational logic circuits. The methodology is based on stochastic model of logic signals and takes correlations and simultaneous switching of signals at logic gate inputs into consideration. In combinational logic synthesis, in order to minimize spurious transitions due to nite propagation delays, it is ...
An optical soliton pulse may be used as a control signal in non-linear optical loop mirror demultiplexers in order to reduce timing-jitter noise and cross-talk. A mathematical model for calculating the width of the soliton switching window and optimizing critical parameters such as walk-off time and pulse width has been presented, and its accuracy is verified by solving the nonlinear Schrodinge...

This signal controls semiconductor switches H-bridge inverter to generate high-power imitation referenc...
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...
This paper develops hybrid control strategies for stabilizing a class of nonlinear systems. Common Lyapunov functions and switched Lyapunov functions are used to establish easily verifiable criteria for the stabilizability of weakly nonlinear systems under switched and impulsive control. Three types of controller switching rules are studied: time-dependent (synchronous), statedependent (asynchr...
