Constrained and unconstrained rearrangement minimization problems related to the p-Laplace operator [PDF]

, 2015
In this paper we consider an unconstrained and a constrained minimization problem related to the boundary value problem\ud −∆pu = f in D, u = 0 on ∂D.\ud In the unconstrained problem we minimize an energy functional relative to a rearrangement class, and

A UV-Method for a Class of Constrained Minimized Problems of Maximum Eigenvalue Functions

Journal of Function Spaces, 2017
In this paper, we apply the UV-algorithm to solve the constrained minimization problem of a maximum eigenvalue function which is the composite function of an affine matrix-valued mapping and its maximum eigenvalue.

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 ...

Outer Approximation Algorithms for DC Programs and Beyond [PDF]

, 2008
We consider the well-known Canonical DC (CDC) optimization problem, relying on an alternative equivalent formulation based on a polar characterization of the constraint, and a novel generalization of this problem, which we name Single Reverse Polar ...

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

A singular local minimizer for the volume- constrained minimal surface problem in a nonconvex domain

Proceedings of the American Mathematical Society, 2018
It has recently been established by Wang and Xia that local minimizers of perimeter within a ball subject to a volume constraint must be spherical caps or planes through the origin. This verifies a conjecture of the authors and is in contrast to the situation of area-minimizing surfaces with prescribed boundary where singularities can be present in ...
