Modeling energy harvesting devices with Non-uniformly polarized piezoceramic materials
Non-uniformly polarized piezoceramic materials can be used in effective energy harvesting devices. Axisymmetric and plane models of electro elastic bodies were studied using applied theory and finite element method (FEM). Applied theory for devices made of parts with longitudinal and transverse polarization was developed.

WIRELESS ENERGY HARVESTING RELAYING NETWORKS UNDER IMPERFECT CSI: THROUGHPUT ANALYSIS
The purpose of this research aims to investigate an amplify-and-forward-based (AF) energy harvesting (EH) system with imperfect channel state information (CSI), where twoend-nodes and one relay are operated in half-duplex mode. Power splitting-based relaying (PSR) protocol is used to transmit information from source to destination by the energy harvesting enabled relay

Power splitting-based relaying (PSR) protocol is used to transmit information from source to destination by the energy harvesting enabled relay. The authors propose that the initial power contained in the battery is...

In this paper, the authors investigate relay selection for decode-and-forward (DF) Full-duplex (FD) based wireless energy harvesting relaying networks. Considering time-switching based relaying (TSR) protocol, this investigation is concerned with the performance of maximum harvested energy relay selection (MHE-RS) scheme. In particular, this work analyzes the system performance in terms of outage probability (OP) and throughput over Rayleigh...

Impact of Hardware Impairments for Power Splitting Relay with wireless Information and EH
In this paper, the research is about analyzing the effect of hardware impairments at the relay node in the cooperative networks which base on amplifying and forwarding. Importantly, in respected to the level of hardware impairments for Rayleigh fading channels. in addition, in term of the throughput which depends on the antenna noise, source's transmission power and the transmission rate, the system's overall performance is also evaluated....
