The splittable flow arc set with capacity and minimum load constraints [PDF]
, 2013 Cataloged from PDF version of article.We study the convex hull of the splittable flow arc set with capacity and minimum load constraints. This set arises as a relaxation of problems where clients have demand for a resource that can be installed in ...

Formalizing Convex Hull Algorithms [PDF]
, 2001 We study the development of formally proved algorithms for computational geometry. The result of this work is a formal description of the basic principles that make convex hull algorithms work and two programs that implement convex hull computation and have been automatically obtained from formally verified mathematical proofs.

Advanced Functional Materials, EarlyView.Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...

Error Analysis of the Convex Hull Method for the Solution of the Distribution System Security Region
EnergiesThe convex hull method is a common approach for the solution of the distribution system security region (DSSR). For the first time, this paper identifies that this method is not applicable to solve many DSSRs.

Convex hulls of spheres and convex hulls of convex polytopes lying on parallel hyperplanes [PDF]
, 2011 Given a set $\Sigma$ of spheres in $\mathbb{E}^d$, with $d\ge{}3$ and $d$ odd, having a fixed number of $m$ distinct radii $\rho_1,\rho_2,...,\rho_m$, we show that the worst-case combinatorial complexity of the convex hull $CH_d(\Sigma)$ of $\Sigma$ is $\

On Rationally Convex Hulls [PDF]
Transactions of the American Mathematical Society, 1973 For a compact set X ⊆ C n X \subseteq {{\mathbf {C}}^n} , let h r ( X ) {h_r}(X) denote the rationally convex hull of X ...

Advanced Healthcare Materials, EarlyView.We characterized the distribution of cargo proteins associated with extracellular vesicles using various exogenous loading methods. In all cases, single‐particle analysis revealed that the distribution of protein content per EV is heterogeneous, following an exponential decay function.

Parameter Identification of Bivariate Fractal Interpolation Surfaces by Using Convex Hulls
Mathematics, 2023 The scope of this article is to identify the parameters of bivariate fractal interpolation surfaces by using convex hulls as bounding volumes of appropriately chosen data points so that the resulting fractal (graph of) function provides a closer fit ...

Advanced Healthcare Materials, EarlyView.This study exploits the plasticity of ASCs‐derived cartilage organoids which generate a perichondrial layer of MSCs when exposed to cyclic chondrogenic/proliferative cues. Using these organoids as building blocks, we develop (i) Phalange Shaped Tissue Engineered Cartilage (Pa‐TECs), recapitulating endochondral ossification suitable for the treatment of

Convex Hull Pricing for Unit Commitment: Survey, Insights, and Discussions
EnergiesEnergy prices are usually determined by the marginal costs obtained by solving economic dispatch problems without considering commitment costs. Hence, generating units are compensated through uplift payments. However, uplift payments may undermine market
