Generalized convex hull construction for materials discovery [PDF]
PHYSICAL REVIEW MATERIALS, 2018 High-throughput computational materials searches generate large databases of locally-stable structures. Conventionally, the needle-in-a-haystack search for the few experimentally-synthesizable compounds is performed using a convex hull construction ...

Convex hulls of spheres and convex hulls of disjoint convex polytopes
Computational Geometry, 2013 Given a set @S of spheres in E^d, with d>=3 and d odd, having a constant number of m distinct radii @r"1,@r"2,...,@r"m, we show that the worst-case combinatorial complexity of the convex hull of @S is @Q(@?"1"= "j"= =3 odd, where n"i spheres have radius @r"i, i=1,2, and @r"2 @r"1, such that their convex hull has combinatorial complexity @W(n"1n"2^@?^d ...

Effect of Performance of Soil Cultivator with Different Surface Textures of Shovel Wing
Agriculture, 2021 Cultivating the soil is a necessary measure to ensure the growth of potatoes, and it has a significant impact on potato yield. In this study, a soil cultivator with a textured shovel wing was designed to address the problem that soil cultivators have ...

Convex Hull Formation for Programmable Matter [PDF]
International Conference of Distributed Computing and Networking, 2018 We envision programmable matter as a system of nanoscale agents (called particles) with very limited computational capabilities that move and compute collectively to achieve a desired goal.

A Convex Primal Formulation for Convex Hull Pricing [PDF]
IEEE Transactions on Power Systems, 2016 In certain electricity markets, because of nonconvexities that arise from their operating characteristics, generators that follow the independent system operator's (ISO's) decisions may fail to recover their cost through sales of energy at locational ...
