Generalized set-valued variational inequalities

open access: yesLe Matematiche, 1997
In this paper, we introduce and study a new class of variational inequalities, which is called generalized set-valued variational inequality. The projection technique is used to establish the equivalence among generalized set-valued variational ...

A domain of influence in the Moore–Gibson–Thompson theory of dipolar bodies

open access: yesJournal of Taibah University for Science, 2020
We establish a domain of influence theorem for the mixed initial-boundary value problem in the context of the Moore–Gibson–Thompson theory of thermoelasticity for dipolar bodies. Based on the data of the mixed problem, we define, for a finite time t>0, a

A system of generalized auxiliary problems principle and a system of variational inequalities [PDF]

open access: yesMathematical Inequalities & Applications, 2001
The author obtains in an elegant manner the approximation-solvability of a system of nonlinear variational and quasivariational inequalities \[ \langle F_1(x^*, y^*), x-x^*\rangle\geq 0\quad\text{for all }x\in X, \] and \[ \langle F_2(x^*, y^*), g(y)- g(y^*)\rangle\geq 0\quad\text{for all }g(y)\in Y, \] where \(X\) and \(Y\), respectively, are nonempty

Auxiliary Sensor-Based Borehole Transient Electromagnetic System for the Nondestructive Inspection of Multipipe Strings

open access: yesSensors, 2017
Transient electromagnetic (TEM) techniques are widely used in the field of geophysical prospecting. In borehole detection, the nondestructive inspection (NDI) of a metal pipe can be performed efficiently using the properties of eddy currents.

Auxiliary Problem Principle of augmented Lagrangian with Varying Core Functions for Large-Scale Structured Convex Problems

open access: yes, 2015
The auxiliary problem principle of augmented Lagrangian (APP-AL), proposed by Cohen and Zhu (1984), aims to find the solution of a constrained optimization problem through a sequence of auxiliary problems involving augmented Lagrangian. The merits of this approach are two folds. First, the core function is usually separable, which makes the subproblems

A Zero-Voltage-Transition H5-Type Transformerless Photovoltaic Grid-Connected Inverter

open access: yesIEEE Access
Efficiency and leakage current are two major issues for transformerless grid-connected inverters (TLI). Soft-switching technology can reduce switching losses, and is a good choice for high-frequency TLIs. Herein, a zero-voltage-transition H5 type (ZVT-H5)
