Intensity Measure Based on a Smooth Inelastic Peak Period for a More Effective Incremental Dynamic Analysis

open access: yesApplied Sciences, 2020
The Incremental Dynamic Analysis (IDA) assesses the global collapse capacity of a structure by plotting its maximum inelastic response, obtained through a non-linear time-history analysis, versus the scaled intensity of different input earthquakes.

Am I Exaggerating? An Affect Intensity Measure Adapted for the Brazilian Context [PDF]

open access: yesPsicologia: Teoria e Pesquisa, 2023
The intensity of affect refers to the strength with which individuals experience their emotions. This study aimed to adapt and seek evidence of validity for the version of the Short Affect Intensity Scale (SAIS) for the Brazilian context.

Scalar and vector-valued fragility analysis of typical Algerian RC bridge piers

open access: yesGrađevinar, 2023
This paper presents and discusses an approach for performing scalar and vector vulnerability assessments of typical Algerian RC bridge piers. Across incremental dynamic analysis, the seismic response was calculated while considering 60 seismic ground ...

适用于全周期结构的速度脉冲型地震动强度表征参数研究

open access: yesDizhen xuebao, 2019
鉴于传统的地震动强度表征参数(IM)不能有效地反映速度脉冲型地震动的破坏特征,需要研究能够在全周期段内表征速度脉冲型地震动强度的参数。本文首先从NGA-West2强震数据库中选取了236条速度脉冲记录,分析了42种地震动参数之间的相似性和相关性,初步给出了速度脉冲型地震动强度的表征参数;其次,利用单自由度体系动力时程分析方法,研究了不同延性μ条件下速度脉冲型地震动强度表征参数与最大非线性位移um之间的相关性系数随周期T的变化特征 ...

Continuum percolation for Cox point processes [PDF]

open access: yes, 2017
We investigate continuum percolation for Cox point processes, that is, Poisson point processes driven by random intensity measures. First, we derive sufficient conditions for the existence of non-trivial sub- and super-critical percolation regimes based ...

Invariant Measures for a Stochastic Fokker-Planck Equation [PDF]

open access: yes, 2017
We study the kinetic Fokker-Planck equation perturbed by a stochastic Vlasov force term. When the noise intensity is not too large, we solve the Cauchy Problem in a class of well-localized (in velocity) functions.

Infrared Small Target Detection Based on Gradient-Intensity Joint Saliency Measure

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Small target detection is an arduous mission in the infrared search and tracking system, especially when the target signal is disturbed by high-intensity background clutters.

Theoretical loss and gambling intensity: a simulation study [PDF]

open access: yes, 2012
Many recent studies of internet gambling—particularly those that have analysed behavioural tracking data—have used variables such as ‘bet size’ and ‘number of games played’ as proxy measures for ‘gambling intensity.’ In this paper, it is argued that the ...
