Radial solutions for a nonlinear problem with $p$-Laplacian
Differential and Integral Equations, 1996 This paper concerns nonlinear singular boundary value problems of the type \[ [t^a|y'(t)|^b y'(t)]'= t^a g(t, y(t), y'(t)),\;t\in I= (0, 1], \quad y(1)= 0= \lim_{t\to 0+} y'(t),\tag{1} \] for constants \(a> 0\), \(b> -1\). Under various technical conditions on the function \(g\), the main theorems establish the existence of bounded solutions, positive ...

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Uniqueness of Large Radial Solutions and Existence of Nonradial Solutions for a Superlinear Dirichlet Problem in Annulii [PDF]
, 2007 Here we establish the existence of infinitely many nonradial solutions for a superlinear Dirichlet problem in annulii. Our proof relies on estimating the number of radial solutions having a prescribed number of nodal regions.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Radial and non-radial positive solutions to a system with critical growth on Rᴺ [PDF]
, 2017 In this talk, I will look at positive entire solutions to the following system involving the critical Sobolev exponent: -Δuᵢ = ∑ⱼ aᵢⱼ uⱼ^{(N+2)/(N-2)} in Rᴺ, uᵢ > 0 in Rᴺ, uᵢ ∈ D¹²(Rᴺ), where i=1,...,k and N ≥ 3.

Radial solutions of equations and inequalities involving the p-Laplacian
Journal of Inequalities and Applications, 1997 Several problems for the differential equation Lpαu=g(r,u)  with  Lpαu=r−α(rα|u′|p−2u′)′ are considered. For α=N−1, the operator Lpα is the radially symmetric p-Laplacian in â„ÂN.

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Radial and Non-radial Numerical Solutions to the Non-linear Elliptic BVP on the Disk [PDF]
, 2018 In the last few decades, much research has gone into proving the existence of solutions to the non-linear elliptic partial differential equations (PDEs) with 0 - Dirichlet boundary conditions on the unit disk. Following the work of Luna

Radial positive solutions for a nonpositone problem in an annulus
Electronic Journal of Differential Equations, 2014 The main purpose of this article is to prove the existence of radial positive solutions for a nonpositone problem in an annulus when the nonlinearity is superlinear and has more than one zero.
