Fuzzy clustering with Minkowski distance [PDF]

open access: yes
Distances in the well known fuzzy c-means algorithm of Bezdek (1973) are measured by the squared Euclidean distance.Other distances have been used as well in fuzzy clustering.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

A distance bound for pseudospectra of matrix polynomials

open access: yesApplied Mathematics Letters, 2007
For \(\ell=0,1,\ldots,m\), given \(n\times n\) complex matrices \(A_\ell\) and \(\Delta_\ell\), we can define the matrix polynomial \[ P(\lambda)=A_m\lambda^m+A_{m-1}\lambda^{m-1}+\cdots+A_1\lambda+A_0, \] and a perturbation of the matrix polynomial \(P(\lambda)\) of the form \[ P_\Delta(\lambda)=(A_m+\Delta_m)\lambda^m+(A_{m-1}+\Delta_{m-1})\lambda^{m-

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

On Some Distance Spectral Characteristics of Trees

open access: yesAxioms
Graham and Pollack in 1971 presented applications of eigenvalues of the distance matrix in addressing problems in data communication systems. Spectral graph theory employs tools from linear algebra to retrieve the properties of a graph from the spectrum ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
