Local Central Limit Theorem for Determinantal Point Processes [PDF]

open access: yes, 2014
We prove a local central limit theorem (LCLT) for the number of points $N(J)$ in a region $J$ in $\mathbb R^d$ specified by a determinantal point process with an Hermitian kernel.

Limit point buckling of a finite beam on a nonlinear foundation

open access: yesTheoretical and Applied Mechanics Letters, 2014
In this paper, we consider an imperfect finite beam lying on a nonlinear foundation, whose dimensionless stiffness is reduced from 1 to k as the beam deflection increases.

Continuum limit of total variation on point clouds [PDF]

open access: yes, 2014
We consider point clouds obtained as random samples of a measure on a Euclidean domain. A graph representing the point cloud is obtained by assigning weights to edges based on the distance between the points they connect.

FUNDAMENTAL MODELS OF STRUCTURAL STABILITY

open access: yesRudarsko-geološko-naftni Zbornik, 2017
In this paper, basic structural stability phenomena are described. After some general comments about stability in the field of civil engineering, four elementary sources of nonlinearity are mentioned: of equilibrium equations, strain (geometry) relations,

Validating a 2-mode asymptotic expansion in computational bifurcation theory (Before introducing HDN for differential operation)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
For error-free computation of high-derivatives of mathematical functions used in engineering applications, hyper-dual numbers (HDN) are receiving much attention in computational mechanics.

Graphs Whose Aα -Spectral Radius Does Not Exceed 2

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let A(G) and D(G) be the adjacency matrix and the degree matrix of a graph G, respectively. For any real α ∈ [0, 1], we consider Aα (G) = αD(G) + (1 − α)A(G) as a graph matrix, whose largest eigenvalue is called the Aα -spectral radius of G.

Non-Linear Instability of Pin-Ended Functionally Graded Material Arches Under Locally Distributed Radial Loads

open access: yesFrontiers in Materials, 2022
The arch is a common structural form in bridge engineering; its collapse is often caused by instability. In this article, in-plane nonlinear instability of pin-ended functionally graded material (FGM) arches with two cross-sectional types under local ...

LIMIT POINT, STRONG LIMIT POINT AND DIRICHLET CONDITIONS FOR DISCRETE HAMILTONIAN SYSTEMS

open access: yesJournal of Applied Analysis & Computation, 2020
Summary: This paper deals with discrete Hamiltonian systems with a singular endpoint. The limit point condition, the strong limit point condition and the Dirichlet condition are studied based on asymptotic behaviors or square summabilities in the maximal domains.

Instabilities, Point Attractors and Limit Cycles in a Inflationary Universe [PDF]

open access: yes, 1995
We study the stability of a scalar inflaton field and analyze its point attractors in the phase space. We show that the value of the inflaton field in the vacuum is a bifurcation parameter and prove the possible existence of a limit cycle by using ...

Multivariate General Compound Point Processes in Limit Order Books

open access: yesRisks, 2020
In this paper, we focus on a new generalization of multivariate general compound Hawkes process (MGCHP), which we referred to as the multivariate general compound point process (MGCPP).
