Covering Properties of Simplexes

open access: yesJournal of Mathematical Analysis and Applications, 1993
Let \(N=\{1,2,\ldots,n\}\) and \(\{e_ 1,e_ 2,\ldots,e_ n\}\) be the unit vectors of \(n\)-dimensional Euclidean space i.e., the \(i^{\text{th}}\) coordinate of \(e_ i\) is 1, the other coordinates are 0. For any \(S \subset N\) let \(\Delta^ S\) denote the convex hull of \(\{e_ j:\;j \in S\}\). These are the simplexes of the title. \textit{E. Sperner} [

Matroids with the Circuit Cover Property

open access: yesEuropean Journal of Combinatorics, 1999
Let \(M\) be a binary matroid and \(p: M \mapsto Z^+\) be a weight on \(M\). A family \(\mathcal F\) of circuits of \(M\) is called a faithful circuit cover of \(M\) with respect to \(p\) if every element \(e\) of \(M\) is contained in precisely \(p(e)\) members of \(\mathcal F\).

Sensitivity of Aerodynamic Characteristics of Paraglider Wing to Properties of Covering Material

open access: yesAUTEX Research Journal, 2020
The paper is theoretically oriented. The main goal is to analyze the sensitivity of aerodynamic characteristics to the properties of the material used for paraglider wing. The paraglider of considerable dimensions is designed without stiffening elements.

Experimental study on axial compressive properties and failure mechanism of unidirectional covered carbon fiber-reinforced polymer composites

open access: yesPolymers and Polymer Composites, 2022
Axial compression performance is one of the main factors considered in the structural design of fiber-reinforced composites. However, the properties of the fibers in such composites are poor because of their orientation structures.

SOME PROPERTIES OF INDUCED COVER FROM FAMILY OF COVERING ROUGH SETS

open access: yesTạp chí Khoa học Đại học Đà Lạt, 2017
Rough set theory is an efficient and essential tool for dealing with vagueness and granularity in information systems. Covering based rough set theory is proposed as a significant generalization of classical rough sets.

Further properties of 1-sequence-covering maps [PDF]

open access: yes, 2008
summary:Some relationships between $1$-sequence-covering maps and weak-open maps or sequence-covering $s$-maps are discussed. These results are used to generalize a result from Lin S., Yan P., {\it Sequence-covering maps of metric spaces\/}, Topology ...

Covering-Based Rough Single Valued Neutrosophic Sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2017
Rough sets theory is a powerful tool to deal with uncertainty and incompleteness of knowledge in information systems. Wang et al. proposed single valued neutrosophic sets as an extension of intuitionistic fuzzy sets to deal with real-world problems.
