Stochastic Delay Logistic Model under Regime Switching

open access: yesAbstract and Applied Analysis, 2012
This paper is concerned with a delay logistical model under regime switching diffusion in random environment. By using generalized Itô formula, Gronwall's inequality, and Young's inequality, some sufficient conditions for existence of global positive ...

The Calculation of Foundation Bed Reliability by Bearing Capacity (Shift) during Operation [PDF]

open access: yesИнженерно-строительный журнал, 2014
New methods of foundation bed reliability calculations by the criterion of the shift when the base is under the influence of horizontal (shifting) forces are made. Initial statistical information is limited.

Improved Chebyshev inequality: new probability bounds with known supremum of PDF

open access: yes, 2018
In this paper, we derive new probability bounds for Chebyshev's inequality if the supremum of the probability density function is known. This result holds for one-dimensional or multivariate continuous probability distributions with finite mean and ...

Almost Sure and Lp Convergence of Split-Step Backward Euler Method for Stochastic Delay Differential Equation

open access: yesAbstract and Applied Analysis, 2014
The convergence of the split-step backward Euler (SSBE) method applied to stochastic differential equation with variable delay is proven in Lp-sense.

Approximating the moments of marginals of high-dimensional distributions

open access: yes, 2012
For probability distributions on $\mathbb{R}^n$, we study the optimal sample size N = N(n,p) that suffices to uniformly approximate the pth moments of all one-dimensional marginals.

Metastability for the contact process on the configuration model with infinite mean degree [PDF]

open access: yes, 2015
We study the contact process on the configuration model with a power law degree distribution, when the exponent is smaller than or equal to two.

Censored Glauber Dynamics for the mean field Ising Model [PDF]

open access: yes, 2008
We study Glauber dynamics for the Ising model on the complete graph on $n$ vertices, known as the Curie-Weiss Model. It is well known that at high temperature ($\beta < 1$) the mixing time is $\Theta(n\log n)$, whereas at low temperature ($\beta > 1$) it

Big Data...a few Outliers = Big Mistakes. Un nuovo processo per l'individuazione di outliers

open access: yesGEOmedia, 2018
The search and identification of outliers is a fundamental step, generally preparatory to the elaborations aimed at obtaining consistent results.

Analysis of a stochastic predator–prey population model with Allee effect and jumps

open access: yesJournal of Inequalities and Applications, 2019
This paper is concerned with a stochastic predator–prey model with Allee effect and Lévy noise. First, by the comparison theorem of stochastic differential equations, we prove that the model has a unique global positive solution starting from the ...

Calculation of reliability of foundation bed in the deformations at the operational stage [PDF]

open access: yesИнженерно-строительный журнал, 2013
Russian standards recommend using certain probabilistic-statistical methods as methods of calculation of reliability of structures and bases at the operational stage.
