Fuzzy Clustering Using the Convex Hull as Geometrical Model
Advances in Fuzzy Systems, 2015 A new approach to fuzzy clustering is proposed in this paper. It aims to relax some constraints imposed by known algorithms using a generalized geometrical model for clusters that is based on the convex hull computation.

Is cranial anatomy indicative of fossoriality? A case study of the mammaliaform Hadrocodium wui
The Anatomical Record, EarlyView.Abstract Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle.

A plane 1.88-spanner for points in convex position
Journal of Computational Geometry, 2016 Let $S$ be a set of $n$ points in the plane that is in convex position. For a real number $t>1$, we say that a point $p$ in $S$ is $t$-good if for every point $q$ of $S$, the shortest-path distance between $p$ and $q$ along the boundary of the convex ...

The Anatomical Record, EarlyView.Abstract Measurement error (ME) in geometric morphometrics has been the subject of countless articles, but none specific to the effect of time lags on landmark digitization error. Yet, especially for visiting scientists working on museum collections, it is not uncommon to collect data in multiple rounds, with interruptions of weeks or years. To explore

On Convex Hull of Orthogonal Scalar Spectral Functions of a Carleman Operator
Boletim da Sociedade Paranaense de Matemática, 2008 In this paper we describe the closed convex hull of orthogonal resolvents of an abstract symmetric operator of defect indices (1; 1), then we study the convex hull of orthogonal spectral functions of a Carleman operator in the Hilbert space L^2(X;mu).

The Anatomical Record, EarlyView.Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated

Convex hulls of bounded curvature
, 1996 In this paper, we consider the problem of computing a convex hull of bounded curvature of a set S of points in the plane, i.e., a set containing S and whose boundary is a curve of bounded curvature of minimal length. We prove that, if the radius of the smallest disk that contains S is greater than 1, such a hull is unique.
