Topology-Constrained NeuroB-Rep: Contact-Aware CAD Reconstruction From 3-D Point Clouds

IEEE Access
Automating the conversion of raw 3D scans into watertight and manufacturable computer-aided design (CAD) models remains challenging, as pipelines based on learning rarely enforce explicit topology such as inter-surface contacts, G1 continuity, and self ...

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

Advanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.
