Electronic Journal of Qualitative Theory of Differential Equations, 2012 In this paper, we study the existence and multiplicity of positive solutions of a class of nonlinear fractional boundary value problems with Dirichlet boundary conditions. By applying the fixed point theory on cones we establish a series of criteria for

Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Electronic Journal of Qualitative Theory of Differential Equations, 2010 The quasilinearization method coupled with the method of upper and lower solutions is used for a class of nonlinear boundary value problems with integral boundary conditions. We obtain some less restrictive sufficient conditions under which corresponding

Advanced Engineering Materials, EarlyView.This study applies machine learning regression to predict chromium layer thickness in decorative trivalent chromium electroplating, using 441 experiments from laboratory‐scale (1L) and pilot‐scale (14L) setups. Tree‐based models, particularly CatBoost, outperformed linear regression by capturing nonlinear parameter interactions (R2$R^2$ up to 0.77 ...

Weak solutions for the p-Laplacian with a nonlinear boundary condition at resonance
Electronic Journal of Differential Equations, 2003 We study the existence of weak solutions to the equation $$ Delta_p u = |u|^{p-2} u+f(x,u) $$ with the nonlinear boundary condition $$ | abla u|^{p-2} frac{partial u}{partial u} = lambda |u|^{p-2} u -h(x,u),.

Electronic Journal of Qualitative Theory of Differential Equations, 2002 The method of quasilinearization for nonlinear impulsive differential equations with linear boundary conditions is studied. The boundary conditions include periodic boundary conditions. It is proved the convergence is quadratic.

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy
Advanced Engineering Materials, EarlyView.A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Existence of solutions to Sturm–Liouville boundary value problems
Electronic Journal of Qualitative Theory of Differential EquationsWe study the solvability of Sturm–Liouville boundary value problems for $x''=f(t,x,x'), t\in(0,1)$. The nonlinearity can be defined on a bounded set and is required to be continuous on its subset.
