An alternative approach, between much others, for mathematical representation of dynamics systems with complex or chaotic behaviour, is a radial basis function neural network using k-means for clustering and optimized by pseudo-inverse and particle swarm optimisation. This paper presents the implementation and study to identify a dynamic system, with nonlinear and chaotic behaviour, called Röss...

this paper introduces a technique for controlling a class of uncertain chaotic systems using an adaptive fuzzy proportional-integrator-derivative (pid) controller with h∞ tracking performance. the purpose of this work is to achieve optimal tracking performance of the controller using backtracking search algorithm (bsa). bsa, which is a novel heuristic algorithm, has an easy structure with singl...

Open multi-agent systems need to cope with the characteristics of the Internet, e.g., dynamic availability of computational resources, latency, and diversity of services. Large-scale multi-agent systems employed on wide-area distributed systems are susceptible to both hardware and software failures. This paper describes AgentScape, a multi-agent system support environment, DARX, a framework for...

A set of multi-trophic population models are described, all of which yield an interesting form of chaotic dynamics-namely, the populations cycle in a periodic fashion, yet the peak abundance within each cycle is erratic and irregular over time. Since there are many ecological and biological systems that are characterized with this same form of "uniform phase-growth and chaotic amplitude (UPCA),...

In recent years chaotic secure communication and chaos synchronization have received ever increasing attention. In this paper a chaotic communication method using extended Kalman filter is presented. The chaotic synchronization is implemented by EKF design in the presence of channel additive noise and processing noise. Encoding chaotic communication is used to achieve a satisfactory, typical se...

This paper presents a novel chaotic spreading sequence for multiple input multiple output multi-carrier direct sequence code division multiple access (MIMO MCDS/CDMA) systems. The effect of multiple access interference can be mitigated by choosing the spreading sequences with appropriate cross-correlation properties. The performance of the system is analysed in multiuser scenario with the aid o...
