A two-box model for equator-to-pole planetary heat transport is extended to include simple atmospheric dynamics. The surface drag coefficient CD is treated as a free parameter and solutions are calculated analytically in terms of the dimensionless planetary parameters eta (atmospheric thickness), omega (rotation rate) and xi (advective capability). Solutions corresponding to maximum entropy pro...

Musical ability determines how well a musician, or a band, can perform. From a listener’s perspective, a musician’s ability is often judged by the subjective overall impression of the music. However, others, such as teachers or talent seekers, use more specific criteria to determine a musician’s ability. Regardless of who is evaluating, judgements of musical ability are still subjective and req...

In this short essay we review the arguments showing that black hole entropy is, at least in part, “entanglement entropy”, i.e., missing information contained in correlations between quantum field fluctuations inside and outside the event horizon. Although the entanglement entropy depends upon the matter field content of the theory, it turns out that so does the Bekenstein-Hawking entropy A/4h̄Gr...

We are concerned with the approximation of undercompressive, regularizationsensitive, nonclassical solutions of hyperbolic systems of conservation laws by high-order accurate, conservative, and semidiscrete finite difference schemes. Nonclassical shock waves can be generated by diffusive and dispersive terms kept in balance. Particular attention is given here to a class of systems of conservati...

It is shown that two reacting cosmological fluids, each of them perfect on its own, which exchange energy and momentum without preserving particle numbers, give rise to an entropy producing ‘reactive’ bulk stress of the system as a whole, as soon as the detailed balance between decay and inverse decay processes is perturbed. This demonstrates explicitly that particle generation is dynamically e...

in this article, multichannel eeg signals of artists and nonartists were analyzed during the performances of visual perception and mental imagery of paintings using cepstrum coefficients. each of the calculated cepstrum coefficients and their parameters such as energy, average, standard deviation and entropy were separately used for distinguishing the two groups. it was also found that a distin...

We use the principle of maximum entropy to propose a parsimonious model for generation of simulated rainfall during the wettest three-month season at a typical location on the east coast of Australia. The model uses a checkerboard copula of maximum entropy to model the joint probability distribution for total seasonal rainfall and a set of two-parameter gamma distributions to model each of the ...

The ultrasonic velocity (U), density (ρ), viscosity (η) have been measured for Cholesteryl oleyl carbonate at different temperatures. From the experimental data, , Free Volume (VF)), Internal Pressure (πi), Relaxation time (τ), Gibbs Free Energy (ΔG), Absorption Coefficient () and Enthalpy (H), Entropy(S) have been calculated.Entropy is a thermodynamic state property, its value depends only on...

The biological effect of one single radiation dose on a living tissue has been described by several radiobiological models. However, the fractionated radiotherapy requires to account for a new magnitude: time. In this paper we explore the biological consequences posed by the mathematical prolongation of a previous model to fractionated treatment. Nonextensive composition rules are introduced to...
