Abstract: Energy efficiency is an important issue in the field of Wireless Sensor Networks (WSNs). So, minimizing the energy consumption in this kind of networks should be an essential consideration. Sleep/wake scheduling mechanism is an efficient approach to handling this issue. In this paper, we propose a Genetic Algorithm-based Sleep-Wake up Area Coverage protocol called GA-SWAC. The proposed protocol puts the minimum of nodes in active mode and adjusts the sensing radius of each active node to decrease the energy consumption while maintaining the network’s coverage. The proposed protocol is simulated. The results demonstrate the efficiency of the proposed protocol in terms of coverage ratio, number of active nodes and energy consumption

Abstract: Estimator designs only using relative displacement between sprung mass and unsprung mass for semi-active suspension system are investigated. Modified sensitivity method controls semi-active suspension directly using relative velocity and MR damper model without calculating absolute velocity and parameter estimator. The comfort evaluation parameters about the driver are presented and the mathematical models of skyhook and modified skyhook ontrol suspension are simulated in Simulink. The comparison results of suggests that modified skyhook control could significantly improve riding comfort and provide more comfortable working conditions for passenger, which can be widely applied on car in the future
