Computer Graphics of the Regular Polygons and their Applications

KnE Engineering, 2018
Abstract. The computer graphics of regular polygons and their applications is a scarcely studied area that allows to create situations of significant learning by its mathematical and geometric content. This research presents the design and programming of regular polygons and composite sacred figures using computational analytical geometry and ...

Accurate, simple and efficient triangulation of a polygon by ear removal with lowest memory consumption

Ceylon Journal of Science, 2016
Polygons can conveniently represent real world objects. In automatic character recognition, shapes of individual letters are represented by polygons. In robotics, obstacles are represented using polygons.

A COMPUTER TECHNIQUE FOR ANALYZING RADIO‐TELEMETRY DATA

Wildlife Society Bulletin, 1980
An interactive computer system to analyze radio‐telemetry data has been developed and used on turkey observations. The program calculates home range by the convex polygon, capture radius, and non‐circular home range methods.

PS: Polygon Streams A Distributed Architecture for Incremental Computation Applied to Graphics [PDF]

, 1991
Polygon Streams is a distributed system with multiple processors and strictly local communication. A unique custom VLSI chip that constitutes an independent processing module forms a stage of the PS pipeline. The number of these modules in PS is a variable that is determined by the application.

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

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

Advanced 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 ...

AI‐Powered Framework for Evaluating Drug Efficacy for Three‐Dimensional In Vitro Cancer Models in Robot‐Assisted Production

Advanced Robotics Research, EarlyView.
An AI‐powered, robot‐assisted framework automatically produces, images, and analyzes 3D tumor spheroids to evaluate drug efficacy. Integrated modules handle spheroid formation, live/dead staining, brightfield imaging, and automated image analysis, including spheroid segmentation, viability and metrics to assess the drug treatment efficacy. The workflow

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment
