Estalishing a nonlinear optimization method for structural reliability analysis [PDF]

open access: yesمهندسی عمران شریف, 2023
The Hasofer-Lind and Rackwitz-Fiessler (HLRF) algorithm, which is based on the first-order reliability method (FORM), is widely used to estimate failure probability, reliability index, and design point in structural reliability analysis.

Effect of pens with an elevated platform on space utilization, skin lesions and growth performance in nursery pigs

open access: yesAnimal, 2021
Environmental enrichment, adequate space and the ability to separate a living area into suitable functional areas are key elements for pig welfare. In this study, a two-level pen for nursery pigs was explored with the aim of analysing the use of space ...

Riemannian Gaussian distributions, random matrix ensembles and diffusion kernels

open access: yesNuclear Physics B, 2021
We show that the Riemannian Gaussian distributions on symmetric spaces, introduced in recent years, are of standard random matrix type. We exploit this to compute analytically marginals of the probability density functions.

A Modification of the PBIL Algorithm Inspired by the CMA-ES Algorithm in Discrete Knapsack Problem

open access: yesApplied Sciences, 2021
The subject of this paper is the comparison of two algorithms belonging to the class of evolutionary algorithms. The first one is the well-known Population-Based Incremental Learning (PBIL) algorithm, while the second one, proposed by us, is a ...

On Probabilistic Risk of Aircraft Collision along Air Corridors

open access: yesAerospace, 2021
The separation of aircraft in cruising flight in air corridors is based on the assurance of an extremely low probability of collision due to position inaccuracy caused by navigation errors, atmospheric disturbances, or other factors.

Encounters and conversations: an office café space as a “magnet space”

open access: yesJapan Architectural Review, 2020
A study was conducted on the activities of office workers at a café space with a lounge in a free‐address office to investigate communication at a “magnet space.” The major results were as follows: (i) The encounter probability between two office workers

New Approaches to Fractal Dimension Estimation With Application to Gray-Scale Images

open access: yesIEEE Access, 2020
Two new approaches for calculating box-counting fractal dimension (FD) estimates for gray-scale images are considered to overcome some of the limitations of the standard box-counting method, which requires setting a threshold in a pre-processing step ...

A generalization of the standard map and its statistical characterization

open access: yesScientific Reports, 2022
From the statistical mechanical point of view, area-preserving maps have great potential and importance. These maps exhibit chaotic and regular behavior separately or together in the available phase space as the control parameter changes.
