300072, China) Abstract: Considering the isentropic efficiency of steam turbine and pump, the theoretical calculation formula of thermal efficiency for the small organic Rankine cycle (ORC) system was deduced. According to the formula derived, the thermal efficiency of four organic working fluids (R134a, R123, R245fa and R227ea) for the small ORC system were calculated under the same condition......
Energy efficiency enhancement of two-way amplifier forward relaying with channel estimation errorSHI Xiao-ye(师晓晔), GE Jian-hua(葛建华), LI Jing(李靖), ZHANG Chen-si(张沉思) (State Key Laboratory of Integrated Service Networks, Xidian University, Xi’an 710071, China)Abstract:In order to save energy consumption of two-way amplifier forward (AF) relaying with channel estimation error, an energy efficiency......
