Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model
Advanced Engineering Materials, EarlyView.Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

A sparsity for decomposing a symmetric matrix
Computers & Mathematics with Applications, 1993 AbstractThis paper studies a sparse configuration for a new class of decomposition derived by the author. Based upon the sparsity, the inverse of a sparse and symmetric matrix and the solution of a system of linear equations can be economically computed. Numerical examples are included.

Hodge decomposition for symmetric matrix fields and the elasticity complex in Lipschitz domains
, 2008 In 1999 M. Eastwood has used the general construction known as the Bernstein-Gelfand-Gelfand (BGG) resolution to prove, at least in smooth situation, the equivalence of the linear elasticity complex and of the de Rham complex in $\mathbf{R}^{3}$.

Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Symmetric Nonnegative Matrix Factorization Based on Box-Constrained Half-Quadratic Optimization
IEEE Access, 2020 Nonnegative Matrix Factorization (NMF) based on half-quadratic (HQ) functions was proven effective and robust when dealing with data contaminated by continuous occlusion according to the half-quadratic optimization theory.

Advanced Engineering Materials, EarlyView.This study reports for the first time the mechanical properties of brazed joints featuring Additively manufactured parts, such parts will likely need to be joined or combined with other components, and brazing offers a way of doing this for complex shapes without distortion. A new shear test methodology developed for such joints is also described.

Adaptive Clustering via Symmetric Nonnegative Matrix Factorization of the Similarity Matrix
Algorithms, 2019 The problem of clustering, that is, the partitioning of data into groups of similar objects, is a key step for many data-mining problems. The algorithm we propose for clustering is based on the symmetric nonnegative matrix factorization (SymNMF) of a ...

The symmetric N-matrix completion problem
Linear Algebra and its Applications, 2005 AbstractAn n×n matrix is called an N-matrix if all its principal minors are negative. In this paper, we are interested in the symmetric N-matrix completion problem, that is, when a partial symmetric N-matrix has a symmetric N-matrix completion. Here, we prove that a partial symmetric N-matrix has a symmetric N-matrix completion if the graph of its ...

The JK method: a procedure for finding the eigenvectors and eigenvalues of a real symmetric matrix
Computer/law journal, 1972 A procedure for finding the eigenvectors and eigenvalues of a real symmetric matrix, dubbed the 'JK method,' is presented. It is similar to Jacobi's classic procedure, but involves only a postmultiplying orthonormal transformation. When both eigenvectors
