Projecting points on the convex hull [PDF]
, 2016 We discuss the problem of projecting points on their convex hull. Points in the interior of the convex hull are moved outwards to the boundary of the convex hull.

A new Approach to Compute Convex Hull [PDF]
, 2011 Virtual reality techniques have proved their importance in almost every field of knowledge, particularly in medical and architecture. Convex hull is an application of virtual reality which is used to draw the boundary of some object inside an image.

The relationship between form and function of the carnivore mandible
The Anatomical Record, EarlyView.Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

General models in min-max planar location [PDF]
This paper studies the problem of deciding whether the present iteration point of some algorithm applied to a planar singlefacility min-max location problem, with distances measured by either anl p -norm or a polyhedral gauge, is optimal or not. It turns

On the Smoothed Complexity of Convex Hulls.
, 2015 We establish an upper bound on the smoothed complexity of convex hulls in $\mathbb{R}^d$ under uniform Euclidean ($\ell^2$) noise. Specifically, let $\{p_1^*, p_2^*, \ldots, p_n^*\}$ be an arbitrary set of $n$ points in the unit ball in $\mathbb{R}^d$ and let $p_i=p_i^*+x_i$, where $x_1, x_2, \ldots, x_n$ are chosen independently from the unit ball of ...

Convex approximations for a class of mixed-integer recourse models [PDF]
We consider mixed-integer recourse (MIR) models with a single recourse constraint.We relate the secondstage value function of such problems to the expected simple integer recourse (SIR) shortage function.

Improvement of volume estimation of stockpile of earthworks using a concave hull- footprint [PDF]
Micro, Macro & Mezzo Geoinformation, 2015 In the estimation of volume of stockpiles of earthworks, the question is no longer whether the data collected is dense and accurate (equipment and techniques capable of accurate data measurement are available), but how to manipulate the data to yield ...
