New Journal of Physics, 2017 We investigate the utility of the convex hull of many Lagrangian tracers to analyze transport properties of turbulent flows with different anisotropy. In direct numerical simulations of statistically homogeneous and stationary Navier–Stokes turbulence ...

Assessment of Postural Sway Area in Single-Leg Balance: A Comparative Analysis of Center-of-Pressure Area Metrics with the Convex Hull approach [PDF]
운동과학PURPOSE Quantifying postural control using Center-of-Pressure (COP) data obtained from a force plate is commonly used in balance assessments, yet the sensitivity of various sway area metrics remains unclear.

The Randomized Integer Convex Hull [PDF]
Discrete & Computational Geometry, 2004 Let \({\mathbb Z}^d\) denote the \(d\)-dimensional integer lattice. Let \(K\subset {\mathbb R}^d\) be a convex body, i.e. a convex compact set with nonempty interior. The integer convex hull \(I(K)\) of \(K\) is the convex hull of all lattice points in \(K\), i.e. \(I(K) = conv(K\cap {\mathbb Z}^d)\).

Relative Convex Hull Determination from Convex Hulls in the Plane [PDF]
, 2015 A new algorithm for the determination of the relative convex hull in the plane of a simple polygon A with respect to another simple polygon B which contains A, is proposed. The relative convex hull is also known as geodesic convex hull, and the problem of its determination in the plane is equivalent to find the shortest curve among all Jordan curves ...

Discrete MathematicsA \emph{thrackle} is a graph drawn in the plane so that every pair of its edges meet exactly once, either at a common end vertex or in a proper crossing. Conway's thrackle conjecture states that the number of edges is at most the number of vertices. It is known that this conjecture holds for linear thrackles, i.e., when the edges are drawn as straight ...
