Global Sensitivity Analysis of Fuzzy Distribution Parameter on Failure Probability and Its Single-Loop Estimation

open access: yesJournal of Applied Mathematics, 2014
An extending Borgonovo’s global sensitivity analysis is proposed to measure the influence of fuzzy distribution parameters on fuzzy failure probability by averaging the shift between the membership functions (MFs) of unconditional and conditional failure

Conditional probability distributions in the wide sense [PDF]

open access: yesProceedings of the American Mathematical Society, 1957
Introduction. Doob [3, p. 29],2 has shown that if Q= [U, Al, u] is a probability space (i.e. cL is a o-field of subsets of a set U and u is a countably additive non-negative measure defined on 'U, normalized by the condition u(U) =1) and cto is a o-subfield of cl, and y is an n-dimensional random variable mapping U into an n-dimensional Euclidean space

Encounter probability analysis of irrigation water and reference crop evapotranspiration in irrigation district

open access: yesJournal of Hydrology and Hydromechanics, 2018
Based on the data series of the annual reference crop evapotranspiration (ET0) and the amount of irrigation water (IR) from 1970 to 2013 in the Luhun irrigation district, the joint probability distribution of ET0 and IR is established using the Gumbel ...

A Simple Markov Chain [PDF]

open access: yesSHS Web of Conferences, 2023
In this paper, Markov chain is used to model the reproduction of the fixed finite population, and use binomial distribution to discuss the probability of gen inheritance between generations population genes and establish transfer matrix ,using ...

Joint probability distribution of winds and waves from wave simulation of 20 years (1989-2008) in Bohai Bay

open access: yesWater Science and Engineering, 2013
The joint probability distribution of wind speed and significant wave height in the Bohai Bay was investigated by comparing the Gumbel logistic model, the Gumbel-Hougaard (GH) copula function, and the Clayton copula function.

Multiscale Data-Driven Energy Estimation and Generation

open access: yesPhysical Review X, 2023
We develop a multiscale approach to estimate high-dimensional probability distributions. Our approach applies to cases in which the energy function (or Hamiltonian) is not known from the start.

Corrigendum: Characterizing a Joint Probability Distribution by Conditionals [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1999
With regard to the theorem in the paper, the second part is, in general, false, and the proof, given in Section 4.2, is in error. Dr K. W. Ng and Professor A. P. Dawid have pointed out the following simple counter-example for two binary random variables x,, x2: P(0, 0) = 0.3, P(0, 1) = 0.2, P(1, 0) = 0.2 and P(1, 1) = 0.3.

Supply–demand scenario generation of active distribution systems using conditional generative adversarial networks

open access: yesEnergy Reports, 2023
The intermittency of distributed renewable energy resources (DRERs) and the fluctuation of load demand make the supply–demand scenario of active distribution systems significantly different from that of traditional radial distribution systems.
