Extreme-value statistics from Lagrangian convex hull analysis for homogeneous turbulent Boussinesq convection and MHD convection [PDF]
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 ...

Convex Hulls under Uncertainty [PDF]
Algorithmica, 2014 We study the convex-hull problem in a probabilistic setting, motivated by the need to handle data uncertainty inherent in many applications, including sensor databases, location-based services and computer vision.

Preprocessing 2D data for fast convex hull computations. [PDF]
PLoS ONE, 2019 This paper presents a method to reduce a set of n 2D points to a smaller set of s 2D points with the property that the convex hull on the smaller set is the same as the convex hull of the original bigger set.

Preconditioning 2D Integer Data for Fast Convex Hull Computations. [PDF]
PLoS ONE, 2016 In order to accelerate computing the convex hull on a set of n points, a heuristic procedure is often applied to reduce the number of points to a set of s points, s ≤ n, which also contains the same hull.

Alpha-Concave Hull, a Generalization of Convex Hull [PDF]
Theoretical Computer Science, 2013 Bounding hull, such as convex hull, concave hull, alpha shapes etc. has vast applications in different areas especially in computational geometry. Alpha shape and concave hull are generalizations of convex hull. Unlike the convex hull, they construct non-convex enclosure on a set of points.

Benchmark dataset for the convex hull of 2D disks [PDF]
Data in Brief, 2019 In this paper, we present a benchmark dataset which can be used to evaluate the algorithms to construct the convex hull of 2D disks. The dataset contains disk arrangements including general and extremely biased cases, which are generated by a C++ program.

From automatic integration to selective control: time-resolved effects of sensory cues on numerical comparison [PDF]
Frontiers in NeuroscienceIntroductionApproximate numerical comparison is often influenced by various non-numerical sensory cues, yet whether they act via uniform inhibition (inhibitory control theory) or cue-weighted integration (sensory integration theory) remains debated ...

Characterizing the spatial structures of competing football teams [PDF]
Scientific ReportsProgress in football analytics is hampered by two main reasons: the unavailability of detailed datasets; and a dearth of meaningful metrics that would aid in gaining insight into the collective action of teams.

Optimal base point selection method based on convex hull construction technology [PDF]
E3S Web of Conferences, 2021 The primary purpose of maritime delimitation is to ensure the maximum internal waters area obtained. In order to grantee the maximum internal waters area obtained with the selected base point, the idea and method of optimal selection of the territorial ...
