Efficient adaptive integration of functions with sharp gradients and cusps in n-dimensional parallelepipeds [PDF]
, 2012 In this paper, we study the efficient numerical integration of functions with sharp gradients and cusps. An adaptive integration algorithm is presented that systematically improves the accuracy of the integration of a set of functions.

On Topp-Leone-G Power Series: Saturation in the Hausdorff Sense and Applications
Mathematics, 2023 This paper discusses the Topp-Leone-G power series class of distributions. The greatest attention is paid to the investigation of intrinsic characteristic “saturation” to the horizontal asymptote in the Hausdorff sense.

Singular Limits in Free Boundary Problems [PDF]
, 1991 We analyze the following class of nonlinear eigenvalue problems: find (uµ) є B x R satisfying (1) Du + µH(a.u - 1)f(u) = 0 in Ω ⊆ R^N, (2) u = O on ∂Ω. Here H (X) is the Heaviside step-function defined by H(X) =0, X ≤ 0 H (X) = 1 X > 0.

Some Notes for Two Generalized Trigonometric Families of Distributions
Axioms, 2022 The paper deals with two general families of cumulative distribution functions based on arctangent function. We provide analysis of the error of the best one-sided Hausdorff approximation for some special cases of these families.

Integrated random processes exhibiting long tails, finite moments and 1/f spectra [PDF]
, 2000 A dynamical model based on a continuous addition of colored shot noises is presented. The resulting process is colored and non-Gaussian. A general expression for the characteristic function of the process is obtained, which, after a scaling assumption ...

A proof of anomalous invasion speeds in a system of coupled Fisher-KPP equations [PDF]
, 2014 This article is concerned with the rigorous validation of anomalous spreading speeds in a system of coupled Fisher-KPP equations of cooperative type. Anomalous spreading refers to a scenario wherein the coupling of two equations leads to faster spreading

Collective motion of macroscopic spheres floating on capillary ripples: Dynamic heterogeneity and dynamic criticality [PDF]
, 2014 When a dense monolayer of macroscopic slightly polydisperse spheres floats on chaotic capillary Faraday waves, a coexistence of large scale convective motion and caging dynamics typical for jammed systems is observed. We subtract the convective mean flow

Analysis of the Chen’s and Pham’s Software Reliability Models
Cybernetics and Information Technologies, 2018 In this paper we study the Hausdorff approximation of the shifted Heaviside step function ht0(t) by sigmoidal functions based on the Chen’s and Pham’s cumulative distribution functions and find an expression for the error of the best approximation.
