Energy efficiency (EE) is an important factor for the deployment of wireless sensor networks. Cooperative communication can help to reduce energy consumption for long distance data transmission. This paper mainly presents the joint optimization of node selection and power allocation for cooperative communication in wireless sensor networks. The proposed brute force approach based on optimal power...
Based on classical electromagnetic theory, the electromagnetic separation calculation model and the formula of electromagnetic body force have been established. Theoretical results indicated that the frequency, current density and electric conductivity can influence the effect of electromagnetic separation. The effects of electromagnetic body force on the microstructure of Al-Si alloy were given in...
