The Maier-Saupe model for binary mixtures of uniaxial discotic nematogens, formulated in a previous study [1], is used to compute and characterize orientational entropy [2] and orientational specific heat. These thermodynamic quantities are used to determine mixture type (ideal or non-ideal) which arise due to their different intrinsic properties, determined by the molecular weight asymmetry ΔM...

The metriplectic framework, which allows for the formulation of an algebraic structure for dissipative systems, is applied to visco-resistive Magneto-Hydrodynamics (MHD), adapting what had already been done for non-ideal Hydrodynamics (HD). The result is obtained by extending the HD symmetric bracket and free energy to include magnetic …eld dynamics and resistive dissipation. The correct equati...

In this paper we show that the vanishing of the scalar curvature of Ruppeiner-like metrics does not characterize the ideal gas. Furthermore, we claim through an example that flatness is not a sufficient condition to establish the absence of interactions in the underlying microscopic model of a thermodynamic system, which poses a limitation on the usefulness of Ruppeiner’s metric and conjecture....

We show that, under rather general assumptions on the form of the entropy function, the energy balance equation for a system in thermodynamic equilibrium is equivalent to a set of nonlinear equations of hydrodynamic type. This set of equations is integrable via the method of characteristics and it provides the equation of state for the gas. The shock wave catastrophe set identifies the phase tr...

Technological scheme for the oxidation of organic wastes in SCW has been proposed. Mathematical models of all apparatuses in the scheme (heat exchangers, chemical reactor, separator) consider specific properties of chemical processes realized in supercritical water (alteration of heat capacity, enthalpy and critical parameters of mixture with changing pressure, temperature and composition). Non...

This thesis studies the problem of balancing power and performance in mobile computers, specifically, trading off power for performance by CPU speed-setting. The traditional approach to power-performance trade-offs assumes that batteries and memory bandwidth are ideal and focuses on lowering the energy per operation. This research, however, shows that non-ideal battery and performance behavior ...

Jones matrix computation is one of the widely used methods in nonlinearitycalculation in laser interferometers. In this paper, the nonlinearity error in developedthree-longitudinal mode heterodyne interferometer (DTLMI) has been mathematicallymodeled at various speeds, by using Jones matrix calculations. This review has been donedespite the fact that simultaneously the main factors including no...

A lattice-model study of double-mutant cycles published in BMC Structural Biology underscores how interactions in non-native conformations can lead to thermodynamic coupling between distant residues in globular proteins, adding to recent advances in delineating the often crucial roles played by disordered conformational ensembles in protein behavior.
