IEEE Access, 2020 To improve the prediction accuracy of the wave propagation velocity of high-speed railway catenary, a method for identifying the fluctuation velocity of catenary (FVC) considering the influence of the accessory parts of catenary (APC) is proposed.

The steady state fluctuation relation for the dissipation function
, 2007 We give a proof of transient fluctuation relations for the entropy production (dissipation function) in nonequilibrium systems, which is valid for most time reversible dynamics. We then consider the conditions under which a transient fluctuation relation

Ensemblization of density-functional theory: Insight from the fluctuation-dissipation theorem
, 2020 Density functional theory can be generalized to mixtures of ground and excited states, for the purpose of determining energies of excitations using low-cost density functional approximations. Adapting approximations originally developed for ground states

Dependent Competing Failure Processes in Reliability Systems
EntropyThis paper deals with a reliability system hit by three types of shocks ranked as harmless, critical, or extreme, depending on their magnitudes, being below H1, between H1 and H2, and above H2, respectively.

Semiclassical gravity theory and quantum fluctuations [PDF]
Physical Review D, 1993 We discuss the limits of validity of the semiclassical theory of gravity in which a classical metric is coupled to the expectation value of the stress tensor. It is argued that this theory is a good approximation only when the fluctuations in the stress tensor are small. We calculate a dimensionless measure of these fluctuations for a scalar field on a

On the Balance between Emigration and Immigration as Random Walks on Non-Negative Integers
MathematicsLife is on a razor’s edge resulting from the random competitive forces of birth and death. We illustrate this aphorism in the context of three Markov chain population models where systematic random immigration events promoting growth are simultaneously ...

Evaluation Method of Wind Power Consumption Capacity Based on Multi-Fractal Theory
Frontiers in Energy Research, 2021 An analysis model of wind power consumption capacity is established with the multi-fractal theory. Firstly, the fluctuation characteristics of wind power are described through multi-fractal parameters, and the correlation between wind power fluctuation ...

Combinatorial Results in Fluctuation Theory
The Annals of Mathematical Statistics, 1963 The main purpose of the paper is to prove a combinatorial extension of a recent theorem of Baxter [6] concerning partial sums of random variables. The method of proof is closely related to that used by Sparre Andersen [1] in his basic 1949 paper which initiated the combinatorial approach to problems in fluctuation theory.

Fluctuation Scaling, Taylor’s Law, and Crime
, 2014 Fluctuation scaling relationships have been observed in a wide range of processes ranging from internet router traffic to measles cases. Taylor’s law is one such scaling relationship and has been widely applied in ecology to understand communities ...
