data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
the second law of thermodynamic (entropy principle) is of special theo-philosophical importance. it seems that this law, which is renowned as “the death of software design” and despite the order in the world, is like an incompatible universal. this article examines the concept of entropy in the three temperature, statistic, and information applications and addresses the contradiction of the sec...
In this study, a dual pressure combined cycle power plant without duct burner for three types of fuel has been investigated. The main objective of this paper is to specify the effect of changing the fuel poperties on cycle performance and finally introducing the best choice. Applying the results, one can see that the highest exergy loss occurs in the combustion chamber and maximum energy and ex...
We construct an entangled quantum Otto engine based on spin-1/2 systems undergoing Dzyaloshinski–Moriya (DM) interaction within a varying magnetic field. We investigate the influence of the DM interaction on basic thermodynamic quantities, including heat transfer, work done, and efficiency and find that the DM interaction importantly influences the engine's thermodynamics. We obtain an expressi...
in this research, energetic andexergetic analysis of calcium oxide formation, co2 emissions, andenvironmental effects during the clinker production process in rotary kilnare investigated. first the energy and exergy analysis of rotary kiln were carried out according to the first and second law of thermodynamics based on dead state, respectively. consequently, the amount of co2 emissions associa...
