New AI‐Assisted Approach for Expanding the Solution Space: Application to Lattice Structure Design

Advanced Engineering Materials, EarlyView.
This work introduces an innovative framework for designing structured materials by ex panding the design space through reparameterization of qualitative variables into continuous structural descriptors. Combined with machine‐learning‐based prediction and multi‐objective optimization, the approach enables the discovery of novel lattice architectures ...

Existence results for nonlinear boundary-value problems with integral boundary conditions

Electronic Journal of Differential Equations, 2005
In this paper, we investigate the existence of solutions for a second order nonlinear boundary-value problem with integral boundary conditions. By using suitable fixed point theorems, we study the cases when the right hand side has convex and ...

Quasilinear Parabolic Systems with Nonlinear Boundary Conditions

Journal of Differential Equations, 2000
Let \(\Omega\) be a smoothly bounded domain in \(\mathbb{R}^n\) with unit outward normal \(\eta\), and let \(M_i> 0\), \(\alpha_i\), and \(m_{ij}\) be nonnegative constants for \(i,j=1,\dots, n\). This paper is considered with the initial-boundary value problem \[ \begin{gathered} \frac {\partial u_i}{\partial t} = \nabla(u_i^{\alpha ^i}\nabla u_i ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Parametrization for non-linear problems with integral boundary conditions

Electronic Journal of Qualitative Theory of Differential Equations, 2012
We consider the integral boundary-value problem for a certain class of non-linear system of ordinary differential equations of the form \begin{equation*} \frac{dx\left(t\right)}{dt} =f\left(t,x\left(t\right)\right), t\in \left[0,T\right],\: x\in \mathbb ...

Reaction-diffusion waves with nonlinear boundary conditions

Networks & Heterogeneous Media, 2013
A reaction-di usion equation with nonlinear boundary condition is considered in a two-dimensional in nite strip. Existence of waves in the bistable case is proved by the Leray-Schauder method.

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

Advanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.
