A class of outer generalized inverses

Linear Algebra and its Applications, 2012
The notion of the Drazin generalized inverse in associative rings and semi-groups, introduced by the author of the present article [Am. Math. Mon. 65, 506--514 (1958; Zbl 0083.02901)] is as follows: Let \(S\) be a semigroup. An element \(b \in S\), is called the Drazin inverse of \(a\) if \(ab=ba,b=bab\) and \(a^{k+1}b=a^k\) for some nonnegative ...

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 ...

A study of the dynamic response of two concentric spheres in the context of thermoelastic diffusion with internal heat source

Case Studies in Thermal Engineering
This work examines the dynamic response of a heat source (inner sphere of radius a) embedded within a concentric spherical body (outer radius b), governed by the one-relaxation-time generalized thermoelastic diffusion theory.

Flexible Krylov Methods for Edge Enhancement in Imaging

Journal of Imaging, 2021
Many successful variational regularization methods employed to solve linear inverse problems in imaging applications (such as image deblurring, image inpainting, and computed tomography) aim at enhancing edges in the solution, and often involve non ...

External and Internal Cracking Caused by Heat Treatment in Laser Powder Bed Fusion‐Fabricated Inconel 738LC Components

Advanced Engineering Materials, EarlyView.
Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias

Advanced Engineering Materials, EarlyView.
Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

A kinetic study and mechanisms of reduction of N, N′-phenylenebis(salicyalideneiminato)cobalt(III) by L-ascorbic acid in DMSO-water medium

Heliyon, 2020
The kinetics of reduction of N, N1-phenylenebis-(salicylideneiminato)cobalt (III), referred to as [Co(Salophen)]+ by L-ascorbic acid (H2A) was studied in mixed aqueous medium (DMSO:H2O; 1:4 v/v) under pseudo-first-order conditions at 33 ± 1 °C, μ = 0.1 ...

Integration of OpenCV‐Based Microscopic Adhesive Volume Measurement Into a Pyiron Workflow for Automated Data Analysis

Advanced Engineering Materials, EarlyView.
Residual adhesive after electrode loading in adhesive‐assisted resistance spot welding is quantified through a traceable experimental‐to‐digital workflow. Chromatic confocal topography provides calibrated surface‐height data, while OpenCV detects the electrode imprint and integrates adhesive height into comparable volume metrics.
