Accurate detection of weld seams for laser welding in real‐world manufacturing
AI Magazine, Volume 44, Issue 4, Page 431-441, Winter 2023., 2023 Abstract Welding is a fabrication process used to join or fuse two mechanical parts. Modern welding machines have automated lasers that follow a predefined weld seam path between the two parts to create a bond. Previous efforts have used simple computer vision edge detectors to automatically detect the weld seam on an image at the junction of two ...

Toward a Novel Energy‐Dissipation Metamaterial with Tensegrity Architecture
Advanced Materials, Volume 35, Issue 26, June 28, 2023., 2023 A new dissipator with a tensegrity‐based architecture that is highly customizable is presented. It has movement amplification capabilities due to its internal geometry and it is possible to control its stiffness and damping by adjusting the pre‐strain. A 3D‐printed prototype is analyzed and its excellent dissipation abilities are confirmed. Furthermore,

Much ado about diversity? The perpetuation of old elites on corporate boards
Managerial and Decision Economics, Volume 43, Issue 8, Page 3263-3285, December 2022., 2022 Despite ubiquitous diversity pledges, many corporate boards still closely resemble those of the past, in that they are largely composed of directors with distinct elite backgrounds. Our study asks why some firms have more elite boards than others. We draw on elite theory and organizational change and stability literature to argue that the elite's ...

Polymer Composites, Volume 43, Issue 7, Page 4417-4436, July 2022., 2022 Abstract The robotic fiber placement (RFP) process depends on continuous fusion bonding and solidifying of prepreg tows onto a substrate by subjecting them to a compression force and heat flux. However the advantages provided when using the RFP to fabricate the composite structures, it has adverse effects due to the induced residual stresses (RSs). The
