Learners’ understanding of the definitions and hierarchical classification of quadrilaterals: towards a theoretical framing [PDF]

open access: yes, 2007
Defining and classifying quadrilaterals, though an established component of the school mathematics curriculum, appears to be a difficult topic for many learners.

The Dynamics of Quadrilateral Folding [PDF]

open access: yesExperimental 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 ...

Are Bilinear Quadrilaterals Better Than Linear Triangles? [PDF]

open access: yes, 1993
This paper compares the theoretical effectiveness of bilinear approximation over quadrilaterals with linear approximation over triangles. Anisotropic mesh transformation is used to generate asymptotically optimally efficient meshes for piecewise linear ...

On quadrilaterals in the suborbital graphs of the normalizer [PDF]

open access: yesTransactions on Combinatorics, 2020
n this paper‎, ‎we investigate suborbital graphs formed by $N\big(\Gamma_0(N)\big)$-invariant equivalence relation induced on $\hat{\mathbb{Q}}$‎. ‎Conditions for being an edge are obtained as a main tool‎, ‎then necessary and sufficient conditions for ...

Generation of hybrid grids over plane domains

open access: yesComputer Assisted Methods in Engineering and Science, 2023
The paper presents an algorithm of coverage 2-D multiconnected domain by trianlges and quadrilaterals. The zone covered with quadrilaterals is structured, thus the zone covered with triangles is unstructured.

RoomSLAM: Simultaneous Localization and Mapping With Objects and Indoor Layout Structure

open access: yesIEEE 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
