CIS (Cu-InSe) thin films were prepared onto glass substrate by the two stage process—generally called bilayer process. At first, Cu layer was deposited onto glass substrate by electron beam evaporation technique and then InSe single layer was deposited on the resulting Cu layer to produce CIS thin film. XRD (X-ray diffraction) analysis revealed that deposited film has an amorphous nature. Elect...

Integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. A new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. The proposed system includes evacuated tub...

Today air conditioning systems have been considered by all people as one of welfarerequirements in buildings and closed environments. Since a considerable part of energy lossoccurs in ordinary modern systems, new strategies and solutions are developed in the field inorder to save amount of energy consumption and observe environmental considerations. Fuzzycontrol is one of these methods which pr...

A new model for cooling flows in X-ray clusters, capable of naturally explaining salient features observed, is proposed. The only requirement is that a significant relativistic component, in the form of cosmic rays (CR), be present in the intra-cluster medium and significantly frozen to the thermal gas. Such an addition qualitatively alters the conventional isobaric thermal instability criterio...

Occurrence of Hysteresis like behavior of resistance of Sb 2 Te 3 film in heating-cooling cycle. Abstract Experimental observations of a peculiar behavior observed on heating and cooling Sb 2 Te 3 films at different heating and cooling rate are detailed. The film regained its original resistance, forming a closed loop, on the completion of the heating-cooling cycle which was reproducible for id...

We simulate the effects of viscous dissipation of waves that are generated by AGN activity in clusters of galaxies. We demonstrate that the amount of viscous heating associated with the dissipation of these waves can offset radiative cooling rates in cooling flow clusters of galaxies. This heating mechanism leads to spatially distributed and approximately symmetrical dissipation. The heating wa...
