WebIn this paper, we develop a fully discrete entropy preserving ADER-Discontinuous Galerkin (ADER-DG) method. To obtain this desired result, we equip the space part of the method with entropy correction terms that balance the entropy production in space, inspired by the work of Abgrall. Whereas for the time-discretization we apply the relaxation approach … WebHigh-order entropy H k(S) = ∑ t∈Σk S t n ⋅H 0(S t) of a length- string is a weighted sum over all contexts of the zero order empirical entropy of symbols having that context H k n …
WebThe term Hh < lg IEI denotes the hth-order empirical entropy of the text, which means that our index is nearly optimal in space apart from lower-order terms, achieving asymptotically the empirical entropy of the text (with a multiplicative constant 1). If the text is highly compressible so that H~ = o (1) and the alphabet size is small, we ... WebJul 25, 2024 · Similar entropy conservative/stable numerical fluxes were adopted in the high-order nodal DG literature, which, in combination with discrete derivative operators using Gauss-Lobatto quadrature points that satisfy the summation-by-parts (SBP) property, yield entropy conservative/stable DG discretizations [ 24, 45, 46 ].
The relationship between entropy, order, and disorder in the Boltzmann equation is so clear among physicists that according to the views of thermodynamic ecologists Sven Jorgensen and Yuri Svirezhev, “it is obvious that entropy is a measure of order or, most likely, disorder in the system.” See more In thermodynamics, entropy is often associated with the amount of order or disorder in a thermodynamic system. This stems from Rudolf Clausius' 1862 assertion that any thermodynamic process always "admits to … See more To highlight the fact that order and disorder are commonly understood to be measured in terms of entropy, below are current science encyclopedia and science dictionary definitions of entropy: • A measure of the unavailability of a system's energy to … See more Entropy has been historically, e.g. by Clausius and Helmholtz, associated with disorder. However, in common speech, order is used to describe organization, structural regularity, … See more In recent years the long-standing use of term "disorder" to discuss entropy has met with some criticism. Critics of the terminology state that entropy is not a measure of 'disorder' … See more This "molecular ordering" entropy perspective traces its origins to molecular movement interpretations developed by Rudolf Clausius in the 1850s, particularly with his 1862 visual conception of molecular disgregation. Similarly, in 1859, after reading a … See more Owing to these early developments, the typical example of entropy change ΔS is that associated with phase change. In solids, for example, … See more In the quest for ultra-cold temperatures, a temperature lowering technique called adiabatic demagnetization is used, where atomic entropy considerations are utilized which can be described in order-disorder terms. In this process, a sample of solid such as chrome … See more WebApr 10, 2024 · Recently, the HfNbZrTi high-entropy alloy (HEA) has received extensive attention due to its exceptional mechanical properties, which is ascribed to the significant lattice distortion and complex structural evolution induced by inherent chemical short-range order (CSRO).

WebFeb 26, 2016 · Moreover, high entropy means that interactions between subsystems are at its maximum, which corresponds better to the definition of a living being. When two gases at different temperatures mix, entropy grows, but that doesn't mean that energy has stopped flowing. Energy is flowing at its best throughout all the molecules.
