The problem of Impulsive effects on stability analysis of high-order BAM neural networks with time delays is investigated in this paper. By using the Lyapunov technique and Razumikhin method, we characterize theoretically the aggregated effects of impulse and stability properties of impulse-free version and then analyze the stabilizing mechanism and destabilizing mechanism of impulses, strength...

In this paper, we present an approach in which synchronization of chaos is used to address identification problems. In particular, we are able to identify (i) the discontinuity points of systems described by piecewise dynamical equations and (ii) the delays of systems described by delay differential equations. Delays and discontinuities are widespread features of the dynamics of both natural an...

We assess the possibility of determining the Hubble constant H0 by measuring time delays between multiple images of supernovae gravitationally lensed by rich clusters of galaxies and combining these delay measurements with detailed cluster-potential models based on other lensing constraints. Such a lensing determination of H0 would be complementary to those obtained from galaxyQSO lensing studi...

The symmetry in a network of oscillators determines the spatiotemporal patterns of activity that can emerge. We study how a delay in the coupling affects symmetry-breaking and -restoring bifurcations. We are able to draw general conclusions in the limit of long delays. For one class of networks we derive a criterion that predicts that delays have a symmetrizing effect. Moreover, we demonstrate ...

Digital lters where unit delays are replaced with frequencydependent delays, such as rst order allpass sections, are often called warped lters since they implement lter specications on a warped non-uniform frequency scale. Warped IIR (WIIR) lters cannot be realized directly due to delayfree loops. Speci c solutions have been known that make WIIR lters realizable but no general approach has been...

Packet losses and delays represent two of the main causes of impairment on packet-based communications. Recent proposals for robust and efficient transmission suggest joint design of coding and routing strategies. This paper introduces a general framework to analyze time diversity in packet-based communications. An algorithm for designing an efficient distribution of information in multiple pac...

In this paper, we first establish a basic theorem on the zeros of general transcendental functions. Based on the basic theorem, we develop a decomposition technique to investigate the stability of some exponential polynomials, that is, to find conditions under which all zeros of the exponential polynomials have negative real parts. The technique combines the D-decomposition and τ -decomposition...

For a family of non-autonomous differential equations with distributed delays, we give sufficient conditions for the global exponential stability of an equilibrium point. This family includes most of the delayed models of neural networks of Hopfield type, with time-varying coefficients and distributed delays. For these models, we establish sufficient conditions for their global exponential stab...

This paper presents the considerations on selecting a multiprocessor MISD architecture for fast implementation of the vision image processing. Using the author’s earlier experience with real-time systems, implementing of specialized hardware processors based on the programmable FPGA systems has been proposed in the pipeline architecture. In particular, the following processors are presented: me...
