In order to demonstrate our research results on managing wireless networks that are used to provide mobile services with a large spectrum of application, we developed the BlueSpot system. This system can be easily used to investigate various open questions concerning wireless networks. Here, we present results that became apparent during our investigations on Bluetooth Scatternets with the aid ...

In this paper, the MPI master-slave parallel genetic algorithm is implemented by analyzing the basic genetic algorithm and parallel MPI program, and building a Linux cluster. This algorithm is used for the test of maximum value problems (Rosen brocks function) .And we acquire the factors influencing the master-slave parallel genetic algorithm by deriving from the analysis of test data. The expe...

INTRODUCTION A novel robotic platform for Natural Orifice Transluminal Endoscopic Surgery (NOTES) is presented in this paper. It aims to tackle two crucial technical barriers which hinder its smooth transition from animal studies to clinical trials: providing effective instrumentations to perform complex NOTES procedures and maintaining the spatial orientation for endoscopic navigation. MATER...

Humans are usually better than autonomous robots in operating in complex environments. In bilateral teleoperation, to take full advantage of the human’s intelligence, experience, and sensory inputs for performing a dexterous task, a possibility is to use the two hands of the user to manipulate two master haptic devices in order to control a slave robot with multiple degrees-of-freedom (DOF); th...

This paper presents a new robust masterslave distribution architecture for multiple populations Evolutionary Computations (EC). It discusses the main advantages and drawbacks of master-slave models over island models for parallel and distributed EC. It also formulates a mathematical model of the master-slave distribution policies in order to show that, contrary to what is implied by current mai...

In this paper time-delay effects on the master–slave synchronization scheme are investigated. Sufficient conditions for master–slave synchronization of Lur’e systems are presented for a known time-delay in the master and slave systems. A delay-dependent synchronization criterion is given based upon a new Lyapunov–Krasovskii function. The derived criterion is a sufficient condition for global as...

Abstract Time synchronization based on IEEE 1588 synchronization protocol aims to synchronize the slave clock to the master clock. Conventional synchronization algorithm focuses on calibrating offset of the slave clock with respect to the master clock. In this paper, a novel method of time synchronization is proposed, the proposed method improves the synchronization precision by considering bot...

This paper investigates the problem of exponential synchronization for a class of master-slave systems with both discrete and distributed time-delays, norm-bounded nonlinear uncertainties and Markovian switching parameters. Using an appropriate Lyapunov-Krasovskii functional, some delay-dependent sufficient conditions and a synchronization law which include the master-slave parameters are estab...

Sliding mode control has been used extensively in robotics to cope with parameters uncertainty, model perturbations and system disturbance. Bilateral robotic teleoperators are often required to provide a haptic interaction in telerobotic applications in which human kinesthetic sense is stimulated locally by remote environment. The paper deals with bilateral control for a force-reflection master...

This article presents a novel adaptive bilateral control scheme for obtaining ideal responses for teleoperation systems with uncertainties. A condition that is equivalent to getting an ideal response in teleoperation has been found to be making the closed-loop dynamics of master and slave manipulators a similar form. An adaptive approach is applied to achieve similarity for the uncertain master...
