In the preceding papers present author gave another proof of existence and uniqueness solution to BCS-Bogoliubov gap equation for superconductivity from viewpoint operator theory, showed that is partially differentiable with respect temperature twice. Thanks these results, we can indeed differentiate thermodynamic potential twice so as obtain entropy specific heat at constant volume a supercond...

Gas-condensate reservoirs contain hydrocarbon fluids with characteristics between oil and gas reservoirs and a high gas-liquid ratio. Due to the large gas-liquid ratio, wellhead choke calculations using the empirical equations such as Gilbert may contain considerable error. In this study, using drill stem test (DST) data of a gas-condensate reservoir, coefficients of Gilbert equation was modifi...

This work proposes a new block based motion estimation and compensation technique applied on the detail images of the wavelet pyramidal decomposition. The algorithm uses two matching criteria, namely the absolute difference and the absolute sum. For a wavelet decomposed one-dimensional step function, it is shown that for odd translations of the step, the absolute sum reaches a smaller minimum t...

There have been numerous reports over the past fifty years of survival of organisms at very low temperatures. Many of these results have been summarized by Luyet and Gehenio.2 Among the metazoa, survival at low temperatures has been reported for nematodes, rotifers, tardigrades and artemia eggs.' Two general results seem to emerge from these cryobiology experiments: (1) If a living system can s...

This is a study of morphisms in the category of finite dimensional absolute valued algebras, whose codomains have dimension four. We begin by citing and transferring a classification of an equivalent category. Thereafter, we give a complete description of morphisms from one-dimensional algebras, partly via solutions of real polynomials, and a complete, explicit description of morphisms from two...
