This paper mainly deals with the almost surely exponential stability and exponential p-th moment stability for a class of stochastic Cohen–Grossberg neural networks with distributed delays and reaction–diffusion term. By constructing suitable Lyapunov functional, employing the nonnegative semi-martingale convergence theorem and applying matrix theory and stochastic analysis technique, two delay...

This paper aims to extend the proportionate adaptation concept design of a class diffusion normalized subband adaptive filter (DNSAF) algorithms. leads four extensions algorithm associated with different step-size variations, namely (DPNSAF), $$\mu $$ -law PNSAF (DMPNSAF), improved (DIPNSAF) and IPNSAF (DIIPNSAF). Subsequently, steady-state performance, stability conditions computational comple...

In this paper, the works on time synchronization in wireless sensor networks are investigated step by step. In particular, the diffusion-based algorithms for global synchronization in large-scale distributed sensor network are intensively focused. We thus propose a fast-converged asynchronous diffusion synchronization scheme in order to improve the performance of the asynchronous averaging diff...

Molecular communication networks consist of transmitters and receivers distributed in a fluid medium. The communication in these networks is realised by the transmitters emitting signalling molecules, which are diffused in the medium to reach the receivers. This paper investigates the properties of noise, or the variance of the receiver output, in molecular communication networks. The noise in ...

in this paper we investigate the effects of broadband infrastructure providing high speed internet, on economic growth in developing countries. we have used two different broadband measures to classify developing countries into two groups for the period 1999-2008. by using logistic diffusion model and iv approach, a nonlinear diffusion model is specified. differences in ceiling of diffusion cur...

Distributed adaptive signal processing and communication networking are rapidly advancing research areas which enable new and powerful signal processing tasks, e.g., distributed speech enhancement in adverse environments. An emerging new paradigm is that of multiple devices cooperating in multiple tasks (MDMT). This is different from the classical wireless sensor network (WSN) setup, in which m...
