In this study, the overall performance of air PV/T, based on energy and exergy analysis has been investigated. Two combinations of air PV/T, which consist of unglazed and glazed air PV/T, are considered. Thermal analysis and numerical calculations were carried out, and the performance parameters of the system for the climate conditions of Kerman were studied. The results are presented in graphs...

this study describes the result of relationship between disc personality types and pay to performance system. also, describe the relationship between herzberg two-factor model and pay to performance. we invited 300 mangers’ of bank refahe kargaran to participate in the study through random selection and received 208 returned responses. the responses rate was 69.3 percent. the data used in this ...

Heat dissipation from electrical appliances is a significant issue with contemporary electrical devices. One factor in the improvement of heat dissipation is the heat transfer performance of the working fluid. In this study, we used plasma arc technology to produce a nanofluid of carbon nanoparticles dispersed in distilled water. In a one-step synthesis, carbon was simultaneously heated and vap...

Trapped magnetic flux is known to degrade the quality factor of superconducting cavities by increasing the surface losses ascribed to the residual resistance. In Nb3Sn cavities, which consist of a thin layer of Nb3Sn coated on a bulk niobium substrate, the bimetallic interface results in a thermal current being generated in the presence of a thermal gradient, which will in turn generate flux th...

The current multi-layer insulation used in the extravehicular mobility unit (EMU) will not be effective in the atmosphere of Mars due to the presence of interstitial gases. Alternative thermal insulation means have been subjected to preliminary evaluation by NASA to attempt to identify a material that will meet the target conductivity of 0.005 W/m-K. This study analyzes numerically the thermal ...

Temperature issues have become a first-order concern for modern computing systems. There are several approaches for dynamic thermal management, including reacting based on some threshold temperature, predicting based on history, or estimating localized temperatures based on performance counters. One possibility for more proactive management is to predict temperatures based on the upcoming instr...

The paper describes an in house made experimental set-up that measures the thermal conductivity of liquids. The measurement principle is based on the Transient Hot Wire Method. The theoretical bases of the measurement method are firstly presented, and then our original experimental implementation is described. The hardware as well as the software design reveals the simple configuration of the m...

General purpose mobile processors present two new design challenges. The first is the need to achieve the best performance while fitting into limited thermal environment and the second is maximizing the battery life of the entire system. The Intel® Pentium® M processor has been developed specifically to target the mobile market and therefore, much emphasis was given to advanced mobile features ...
