Progress in high-performance computing (HPC) fundamentally requires effective thermal dissipation. At present this challenge is viewed in terms of two distinct architectural components: a computational substrate and a heat-exchange substrate. Typically these two components are viewed as performing conceptually different functions that are independent up to optimization constraints applied when ...

In the present work, we develop a theoretical analysis to minimize the entropy generation of a thermo-electric cooler (TEC), which can be used to cool a processor. We have applied an analysis of first and second law of the Thermodynamics to a TEC. We consider the entropy generation equation as the objective function and the first law as a restriction, in accordance with the variational calculus...

This conference has seen much discussion about non-gravitational heating of the intracluster medium, as required to reduce cooling rates and central densities sufficiently to explain the observed properties of galaxy clusters. The amount of energy input required is often computed by comparing to the entropy profile that would be expected from gravitational processes alone, as determined, for ex...

The present paper presents a thermodynamic approach to assess the quality of human-thermal environment interaction and quantify thermal comfort. The approach involves development of entropy generation term by applying second law of thermodynamics to the combined human-environment system. The entropy generation term combines both human thermal physiological responses and thermal environmental va...

Directionality in populations of replicating organisms can be parametrized in terms of a statistical concept: evolutionary entropy. This parameter, a measure of the variability in the age of reproducing individuals in a population, is isometric with the macroscopic variable body size. Evolutionary trends in entropy due to mutation and natural selection fall into patterns modulated by ecological...

Abstract: The diameter and configuration of tubes are important design parameters of power condensers. If a proper tube diameter is applied during the design of a power unit, a high energy efficiency of the condenser itself can be achieved and the performance of the whole power generation unit can be improved. If a tube assembly is to be replaced, one should verify whether the chosen condenser ...
