Hace 1 día · In information theory, the entropy of a random variable is the average level of "information", "surprise", or "uncertainty" inherent to the variable's possible outcomes.
Hace 3 días · S(B) − S(A) ≥ ∫B AdQ T. for an irreversible thermodynamic process between an initial state A and final state B. To prove this inequality, Fermi argues that one can form a cycle by joining to the irreversible transformation a reversible transformation from A to B run in reverse, i.e., from B to A.
Hace 1 día · The examination of the total entropy generation reveals that the entrance pipe exhibits the least amount of entropy loss, measuring below 0.045 [W/K] across all five models. This observation suggests that the inlet has a negligible or little impact on the development of entropy inside the pump.
Hace 2 días · The results reveal that the proposed method provides an improved dynamic response of the drive under changing operating conditions with a reduction of 28% in computational burden and 38% in total ...
Hace 3 días · Total scattering measurements and pair distribution function analysis of slow-cooled and quenched samples support this view. In general, we demonstrate that SRO effects in high entropy materials are less prevalent as more components are added in, provided the pairwise interaction strengths remain comparable, while local distortions are less affected by the number of components.
Hace 3 días · The magnetic behaviors and magnetocaloric properties of these alloys were analyzed to investigate the competition between magnetic and lattice contributions to the total entropy change. Finally, the mutually contradictory role of magnetic and lattice contributions was demonstrated.
Hace 3 días · An idealized high entropy oxide is characterized by perfect chemical disorder and perfect positional order. In this work, we investigate the extent to which short-range order (SRO) and local structural distortions impede that idealized scenario. Working in the entropy stabilized $\alpha$-PbO$_2$ structure, we compare a two-component system, (Ti,Zr)O$_2$, with a four-component system, (Ti,Zr,Hf ...
