Impact of a typical scanner delay processing parameter on local microstructure in metallic laser-based powder bed fusion

Additive Manufacturing Letters
In laser-based powder bed fusion of metals (PBF-LB/M), variations in laser scanner movements, particularly lesser-studied parameters like scanner delays that control laser directional changes, can influence the microstructure in a part during fabrication

Computing medial axis of a simple polygon in linear time based on R-L sequence

Graphical Models
Medial axis computation has wide applications in pattern recognition, image processing, finite element mesh generation, and CNC tool path extraction. Aiming to explore intrinsic geometric attributes of the medial axis of a simple polygon which can be ...

Prescriptive unitarity from positive geometries

Journal of High Energy Physics
In this paper, we define the momentum amplituhedron in the four-dimensional split-signature space of dual momenta. It encodes scattering amplitudes at tree level and loop integrands for N $$ \mathcal{N} $$ = 4 super Yang-Mills in the planar sector.

Radiation fields created by accelerated relativistic charges: A simple approach based on inertial moving charges

Results in Physics, 2019
An electrical circuit is considered a polygon in that it has edges and nodes. The moving (let’s say, relativistic) charges that change their velocity directions (i.e., are accelerating), radiate, and we confront this radiation with the well-known fact ...
