Extreme value theory for moving average processes with light-tailed innovations [PDF]

open access: yes, 2005
We consider stationary infinite moving average processes of the form $Y_n = \sum c_i Z_{n+i}$, where the sum ranges over the integers, (Z_i) is a sequence of iid random variables with ``light tails'' and (c_i) is a sequence of positive and summable ...

More On P-Union and P-Intersection of Neutrosophic Soft Cubic Set [PDF]

open access: yesNeutrosophic Sets and Systems, 2017
The P-union ,P-intersection, P-OR and P-AND of neutrosophic soft cubic sets are introduced and their related properties are investigated. We show that the P-union and the P-intersection of two internal neutrosophic soft cubic sets are also internal ...

Tail asymptotics for cumulative processes sampled at heavy-tailed random times with applications to queueing models in Markovian environments [PDF]

open access: yes, 2013
This paper considers the tail asymptotics for a cumulative process $\{B(t); t \ge 0\}$ sampled at a heavy-tailed random time $T$. The main contribution of this paper is to establish several sufficient conditions for the asymptotic equality ${\sf P}(B(T) >

An Experimental and Numerical Study of CO2–Brine-Synthetic Sandstone Interactions under High-Pressure (P)–Temperature (T) Reservoir Conditions

open access: yesApplied Sciences, 2019
The interaction between CO2 and rock during the process of CO2 capture and storage was investigated via reactions of CO2, formation water, and synthetic sandstone cores in a stainless-steel reactor under high pressure and temperature. Numerical modelling

Multiplicity results for an impulsive boundary value problem of p(t)-Kirchhoff type via critical point theory [PDF]

open access: yesOpuscula Mathematica, 2016
In this paper we obtain existence results of \(k\) distinct pairs nontrivial solutions for an impulsive boundary value problem of \(p(t)\)-Kirchhoff type under certain conditions on the parameter \(\lambda\).

The Multiplicative Inverse Eigenvalue Problem over an Algebraically Closed Field [PDF]

open access: yes, 2000
Let $M$ be a square matrix and let $p(t)$ be a monic polynomial of degree $n$. Let $Z$ be a set of $n\times n$ matrices. The multiplicative inverse eigenvalue problem asks for the construction of a matrix in $Z$ such that the product matrix $MZ$ has ...

Structural deformation and geochronology of the ductile shear zone along the southern margin of the Foping dome, South Qinling

open access: yesDizhi lixue xuebao
Objective  A typical granulite–migmatite–gneiss dome developed in the Foping area of the central Qinling orogenic belt. This area is key to studying the metamorphic deformation of continental crust and the Mesozoic tectonic evolution of Qinling.

Instability of the solitary waves for the generalized Boussinesq equations [PDF]

open access: yes, 2018
In this work, we consider the following generalized Boussinesq equation \begin{align*} \partial_{t}^2u-\partial_{x}^2u+\partial_{x}^2(\partial_{x}^2u+|u|^{p}u)=0,\qquad (t,x)\in\mathbb R\times \mathbb R, \end{align*} with ...

Inhomogeneous parabolic equations on unbounded metric measure spaces [PDF]

open access: yes, 2011
We study inhomogeneous semilinear parabolic equations with source term f independent of time u_{t}={\Delta}u+u^{p}+f(x) on a metric measure space, subject to the conditions that f(x)\geq 0 and u(0,x)=\phi(x)\geq 0.

Closedness type regularity conditions for surjectivity results involving the sum of two maximal monotone operators

open access: yes, 2010
In this note we provide regularity conditions of closedness type which guarantee some surjectivity results concerning the sum of two maximal monotone operators by using representative functions.
