A domain decomposition method for approximating the conformal modules of long quadrilaterals [PDF]
, 1991 This paper is concerned with the study of a domain decomposition method for approximating the conformal modules of long quadrilaterals. The method has been studied already by us and also by D Gaier and W K Hayman, but only in connection with a special ...

The Interplay of Curvature, Geometry, and Topology Shapes Tissue Organisation in Epithelial Shells [PDF]
Advanced Science, EarlyView.Purely geometric 3D Voronoi models predict the organisation of epithelial shells. The interplay of curvature, geometry, and topology enriches the number of pentagons in shells with lower number of cells. Small MDCK cysts and Mouse embryos match the top polygonal configurations in a compactness‐based ranking derived from the Voronoi model. In conclusion,

On the numerical performance of a domain decomposition method for conformal mapping [PDF]
, 1989 This paper is a sequel to a recent paper [14], concerning a domain decomposition method (hereafter referred to as DDM ) for the conformal mapping of a certain class of quadrilaterals.

The Dynamics of Quadrilateral Folding [PDF]
Experimental Mathematics, 1993 When a quadrilateral undergoes a certain infinite folding process, an intricate curve is traced out by its transformed vertices. The curve possesses attractive symmetry properties. We study the folding as a dynamical system in C 4, which is partially described by a billiard-like dynamical system on the bounded component of an elliptic curve associated ...

Learners’ understanding of the definitions and hierarchical classification of quadrilaterals: towards a theoretical framing [PDF]
, 2007 Defining and classifying quadrilaterals, though an established component of the school mathematics curriculum, appears to be a difficult topic for many learners.

RoomSLAM: Simultaneous Localization and Mapping With Objects and Indoor Layout Structure
IEEE Access, 2020 This article presents RoomSLAM, a Simultaneous Localization and Mapping (SLAM) method for mobile robots in indoor environments where environments are modeled by points and quadrilaterals in 2D space. Points represent positions of semantic objects whereas
