Energies, 2023 Many recent studies show that the performance of Savonius turbines can be considerably increased by using wind deflectors. Axisymmetric deflectors are particularly interesting; they concentrate the wind flow in all directions.

Sharp isoperimetric inequalities via the ABP [PDF]
, 2016 Given an arbitrary convex cone of Rn, we find a geometric class of homogeneous weights for which balls centered at the origin and intersected with the cone are minimizers of the weighted isoperimetric problem in the convex cone.

Lifts of convex sets and cone factorizations [PDF]
, 2012 In this paper we address the basic geometric question of when a given convex set is the image under a linear map of an affine slice of a given closed convex cone.

Toward Guaranteed Illumination Models for Non-Convex Objects [PDF]
, 2013 Illumination variation remains a central challenge in object detection and recognition. Existing analyses of illumination variation typically pertain to convex, Lambertian objects, and guarantee quality of approximation in an average case sense.

From Steiner Formulas for Cones to Concentration of Intrinsic Volumes [PDF]
, 2014 The intrinsic volumes of a convex cone are geometric functionals that return basic structural information about the cone. Recent research has demonstrated that conic intrinsic volumes are valuable for understanding the behavior of random convex ...

Equivalent relaxations of optimal power flow [PDF]
, 2014 Several convex relaxations of the optimal power flow (OPF) problem have recently been developed using both bus injection models and branch flow models.

$Star^1$-convex functions on tropical linear spaces of complete graphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 Given a fan $\Delta$ and a cone $\sigma \in \Delta$ let $star^1(\sigma )$ be the set of cones that contain $\sigma$ and are one dimension bigger than $\sigma$ . In this paper we study two cones of piecewise linear functions defined on $\delta$ : the cone

A cone theoretic Krein-Milman theorem in semitopological cones [PDF]
Sahand Communications in Mathematical Analysis, 2018 In this paper, a Krein-Milman type theorem in $T_0$ semitopological cone is proved, in general. In fact, it is shown that in any locally convex $T_0$ semitopological cone, every convex compact saturated subset is the compact saturated convex hull of ...

Semidefinite descriptions of the convex hull of rotation matrices [PDF]
, 2014 We study the convex hull of $SO(n)$, thought of as the set of $n\times n$ orthogonal matrices with unit determinant, from the point of view of semidefinite programming. We show that the convex hull of $SO(n)$ is doubly spectrahedral, i.e. both it and its
