Containment orders for similar ellipses with a common center
نویسندگان
چکیده
Every .nite two-dimensional partially ordered set has an inclusion representation by similar noncircular ellipses centered at the origin. The representing ellipses have the same ratio r of minor axis length to major axis length, and any r ∈ (0; 1) can be used for the representation. c © 2002 Elsevier Science B.V. All rights reserved.

Solvation Force of Ellipse-Shaped Molecules Moving in One Dimension and Confined between Two Parallel Planar Walls
The model fluids containing hard ellipses (HEs) and Gay-Berne (GB) particles where their center is moving in one dimension and confined between two parallel walls with different interactions are investigated using Monte Carlo simulation, NVT ensemble. The dependency of fluid pressure with respect to the wall distances is studied. The oscillatory behaviors are seen in this quantity against ...
متن کاملVisualizing set relations and cardinalities using Venn and Euler diagrams
In medicine, genetics, criminology and various other areas, Venn and Euler diagrams are used to visualize data set relations and their cardinalities. The data sets are represented by closed curves and the data set relationships are depicted by the overlaps between these curves. Both the sets and their intersections are easily visible as the closed curves are preattentively processed and form co...
متن کاملA Multi-Layered Discourse Analysis of Students’ Classroom Talk in Two Contexts: Rural vs. Urban
This study aimed at discussing and representing discourse analysis of classroom talk in two contexts. It is significant, since it considers different genres of talk, cultural and social identities, social relations, different ideologies and many other aspects in this analysis. It attempts to analyze the dominant classroom patterns in two contexts. Two cases of study were analyzed in this study:...
متن کاملGeometric Containment Orders: A Survey
A partially ordered set (X,≺) is a geometric containment order of a particular type if there is a mapping from X into similarly shaped objects in a finite-dimensional Euclidean space that preserves ≺ by proper inclusion. This survey describes most of what is presently known about geometric containment orders. Highlighted shapes include angular regions, convex polygons and circles in the plane, ...
متن کاملA Non Local Quantitative Characterization of Ellipses Leading to a Solvable Differential Relation
In this paper we prove that there are no domains E ⊂ R2, other than the ellipses, such that the Lebesgue measure of the intersection of E and its homothetic image εE translated to a boundary point q ∈ ∂E is independent of q, provided that E is ”centered” at a certain interior point O ∈ E (the center of homothety). Similar problems arise in various fields of mathematics, including, for example, ...
