CONSIDERATIONS ON THE SHAPE OF DISCHARGING CHAMBERS FOR THE ELECTRO-HYDRAULIC DEFORMING METHOD

Journal of Industrial Design and Engineering Graphics, 2022
The electro-hydraulic plastic deforming method belongs to non-conventional plastic deforming techniques class. The shape of the discharging chamber and of the energy concentrators influences workpiece machining, along with the other parameters of the ...

Positive Solutions of a Nonlinear Fourth-order Integral Boundary Value Problem

Annals of the West University of Timisoara: Mathematics and Computer Science, 2016
In this paper, the existence of positive solutions for a nonlinear fourth-order two-point boundary value problem with integral condition is investigated. By using Krasnoselskii’s fixed point theorem on cones, sufficient conditions for the existence of at

A necessary and sufficient condition for the existence of positive solutions to singular boundary-value problems of higher order differential equations

Electronic Journal of Differential Equations, 2006
By constructing some special cones and using fixed point theorem of cone expansion and compression, this paper presents some necessary and sufficient conditions for the existence of $C^{4n-2}$ positive solutions to a class of singular boundary-value

Three positive solutions for a system of singular generalized Lidstone problems

Electronic Journal of Differential Equations, 2009
In this article, we show the existence of at least three positive solutions for the system of singular generalized Lidstone boundary value problems $displaylines{ (-1)^m x^{(2m)}=a(t)f_1(t,x,-x'',dots,(-1)^{m-1}x^{(2m-2)},y,-y'',cr dots,(-1)^{n-1}y^{

Positive periodic solutions of neutral functional differential equations with a parameter and impulse

Electronic Journal of Differential Equations, 2008
In this paper, we consider first-order neutral differential equations with a parameter and impulse in the form of $$displaylines{ frac{d}{dt}[x(t)-c x(t-gamma)]=-a(t)g(x(h_1(t)))x(t)+lambda b(t) fig(x(h_2(t))ig),quad t eq t_j;cr Delta ig[x(t)-c x(t ...

Positive solutions to boundary-value problems of p-Laplacian fractional differential equations with a parameter in the boundary

Electronic Journal of Differential Equations, 2012
In this article, we consider the following boundary-value problem of nonlinear fractional differential equation with $p$-Laplacian operator $$displaylines{ D_{0+}^eta(phi_p(D_{0+}^alpha u(t)))+a(t)f(u)=0, quad 0<t<1, cr u(0)=gamma u(xi)+lambda,
