Geometry on arc spaces of algebraic varieties

, 2000
This paper is a survey on arc spaces, a recent topic in algebraic geometry and singularity theory. The geometry of the arc space of an algebraic variety yields several new geometric invariants and brings new light to some classical invariants.Comment: 22

Prediction of deposition bead geometry in wire arc additive manufacturing using machine learning

Journal of Materials Research and Technology, 2022
The deposition bead geometry in the arc strike zone is often abnormal compared with that in the middle deposition zone. The accumulation of these errors in the deposition process results in defects in the overall geometry of the deposition bead.

Lidar arc scan uncertainty reduction through scanning geometry optimization

, 2015
. Doppler lidars are frequently operated in a mode referred to as arc scans, wherein the lidar beam scans across a sector with a fixed elevation angle and the resulting measurements are used to derive an estimate of the n minute horizontal mean wind ...

Geometrical Relations Between Slab Dip and the Location of Volcanic Arcs and Back‐Arc Spreading Centers

Geochemistry, Geophysics, Geosystems, 2023
A global study of subduction zone dynamics indicates that the thermal structure of the overriding plate may control arc location. A fast convergence rate and a steep slab dip bring a hotter mantle further into the wedge corner, forming arc volcanoes ...

Geometry and Distortion Prediction of Multiple Layers for Wire Arc Additive Manufacturing with Artificial Neural Networks

Applied Sciences, 2021
Wire arc additive manufacturing (WAAM) is a direct energy deposition (DED) process with high deposition rates, but deformation and distortion can occur due to the high energy input and resulting strains.
