In this paper analytical travel time model for the computation of cycle times and throughput performance of the multi-tier shuttle-based storage and retrieval system, is presented. The proposed model considers the real operating characteristics of the shuttle carrier and the elevators lifting table. Assuming uniform distributed storage locations and the probability theory, expressions for the e...

The life time of a component is defined by the reliability demands place on it due to its operating environment and operation conditions. To evaluate the necessarily thermal / power cycle stability of a power semiconductor module in a hybrid electrical vehicle (HEV), a vehicle driving cycle profile is used to calculate the thermal reliability requirements. The calculations are based on power lo...

An irreversible Maisotsenko reciprocating Brayton cycle (MRBC) model is established using the finite time thermodynamic (FTT) theory and taking the heat transfer loss (HTL), piston friction loss (PFL), and internal irreversible losses (IILs) into consideration in this paper. A calculation flowchart of the power output (P) and efficiency (η) of the cycle is provided, and the effects of the mass ...

this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...
