remote sensing using small spacecraft arising from multi-objective economic activity problems is getting more and more developed. these satellites require very accurate pointing to specific locations of interest, with high reliability and small latency. the space borne imaging systems always attempted to achieve the highest ground resolution possible with the available technology at the given t...

The usage and applicability of Information and Communication Technology (ICT) is increased from the past three decades. Monitoring quality-of-Service (QoS) pertaining to networks is a major challenge for the researchers and academicians. Bandwidth, Latency, Jitter, Loss of data and security are some of the important parameters related to the network QoS. Especially security plays an important r...

In this paper, a novel scheme for synchronizing four drive and four response systems is proposed by the authors. The idea of multi switching and dual combination synchronization is extended to dual combination-combination multi switching synchronization involving eight chaotic systems and is a first of its kind. Due to the multiple combination of chaotic systems and multi switching the resultan...

An important problem in nonlinear science is the unknown parameters estimation in Loranz chaotic system. Clearly, the parameter estimation for chaotic systems is a multidimensional continuous optimization problem, where the optimization goal is to minimize mean squared errors (MSEs) between real and estimated responses for a number of given samples. The Bees algorithm (BA) is a new member of me...

We suggest and experimentally demonstrate a chaotic memory resistor (memristor). The core of our approach is to use a resistive system whose equations of motion for its internal state variables are similar to those describing a particle in a multi-well potential. Using a memristor emulator, the chaotic memristor is realized and its chaotic properties are measured. A Poincaré plot showing chaos ...

The control of nonlinear chaotic system and the estimation of parameters is a vital issue in nonlinear science. Studies on parameter estimation for chaotic systems have been investigated recently. A variant of Particle Swarm Optimization (PSO) known as Chaotic Multi Swarm Particle Swarm Optimization (CMS-PSO) is proposed which is inspired from the metaphor of ecological co-habitation of species...

In distributed systems deployed on the world-wide scale, the primary determinant of performance is latency. This technical report illustrates the importance of latency minimization in such systems by analysis of realistic world-wide distributed computing examples. It then develops a technique for distributed systems interaction — employing mobile Java objects as ambassadors, acting for clients ...
