Phenomenological two – gap model for the specific heat of
– We show that the specific heat of the superconductor MgB2 in zero field, for which significant non–BCS features have been reported, can be fitted, essentially within experimental error, over the entire range of temperature to Tc by a phenomenological two–gap model. The resulting gap parameters agree with previous determinations from band–structure calculations, and from various spectroscopic ...

متن کاملNon-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production
In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
متن کاملAutonomous Wireless Heat Energy Meter based on Piezoelectric Energy Harvester for Heat Energy Measurement in Building Complexes
This paper presents a platform for power autonomous wireless energy meter device using piezoelectric energy harvesters. This device can be mainly used for measuring the share of heat energy consumption in a fair manner in building complex with central heat energy system. In the suggested device, the piezoelectric energy harvester is also used as a flow-meter to reduce the power consumption of t...
متن کاملSpecific heat of random fractal energy spectra.
The specific heat corresponding to systems with deterministic fractal energy spectra is known to present logarithmic-periodic oscillations as a function of the temperature T in the low T region around a mean value given by a characteristic dimension of the energy spectrum. In general, it is considered that the presence of disorder does not affect strongly these results, and that the fractal str...
