Evaluation of Metaheuristic-Based Methods for Optimization of Truss Structures via Various Algorithms and Lèvy Flight Modification

open access: yesBuildings, 2021
Truss structures are one of the major civil engineering members studied in the optimization research area. In this area, various optimization applications such as topology, size, cost, weight, material usage, etc., can be conducted for different truss ...

Multiplicity dependence of (multi-)strange hadron production in proton-proton collisions at √s = 13 TeV [PDF]

open access: yes, 2020
The production rates and the transverse momentum distribution of strange hadrons at mid-rapidity (| y| < 0.5) are measured in proton-proton collisions at s = 13 TeV as a function of the charged particle multiplicity, using the ALICE ...

The Lévy Flight of Cities: Analyzing Social-Economical Trajectories with Auto-Embedding

open access: yesDiscrete Dynamics in Nature and Society, 2022
Lévy flights are useful in stochastic measurement, such as biology, human mobility, and financial mathematics, where trajectories contain many short flights and some long flights, and the step-lengths follow a power-law distribution. For cities inhabited

Characterizing Human Mobility Patterns in a Large Street Network

open access: yes, 2009
Previous studies demonstrated empirically that human mobility exhibits Levy flight behaviour. However, our knowledge of the mechanisms governing this Levy flight behaviour remains limited.

The fractional Fisher information and the central limit theorem for stable laws [PDF]

open access: yes, 2015
A new information-theoretic approach to the central limit theorem for stable laws is presented. The main novelty is the concept of relative fractional Fisher information, which shares most of the properties of the classical one, included Blachman-Stam ...

Levy Flights in Inhomogeneous Media

open access: yes, 2003
We investigate the impact of external periodic potentials on superdiffusive random walks known as Levy flights and show that even strongly superdiffusive transport is substantially affected by the external field.

Anomalous fluctuation relations [PDF]

open access: yes, 2013
We study Fluctuation Relations (FRs) for dynamics that are anomalous, in the sense that the diffusive properties strongly deviate from the ones of standard Brownian motion. We first briefly review the concept of transient work FRs for stochastic dynamics

Reconfiguration Strategy for DC Distribution Network Fault Recovery Based on Hybrid Particle Swarm Optimization

open access: yesEnergies, 2021
DC distribution network faults seriously affect the reliability of system power supply. Therefore, this paper proposes a fault recovery reconfiguration strategy for DC distribution networks, based on hybrid particle swarm optimization.

Indirect Evidence for L\'evy Walks in Squeeze Film Damping

open access: yes, 2010
Molecular flow gas damping of mechanical motion in confined geometries, and its associated noise, is important in a variety of fields, including precision measurement, gravitational wave detection, and MEMS devices.
