n-fold Commutative Hyper K-ideals

 In this paper, we aresupposed to introduce the definitions of n-fold commutative, andimplicative hyper K-ideals. These definitions are thegeneralizations of the definitions of commutative, andimplicative hyper K-ideals, respectively, which have been definedin [12]. Then we obtain some related results. In particular wedetermine the relationships between n-fold implicative hyperK-ideal and n-fol...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A k-Structure Generalization of the Theory of 2-Structures

Ehrenfeucht. A. and R. McConnell, A k-structure generalization of the theory of 2-structures, Theoretical Computer Science 132 (1994) 209-227. The prime tree decomposition of graphs facilitates the solution of a number of important combinatorial problems. The decomposition is also known as modular decomposition and substitution decomposition. It has been generalized to 2-structures and to k-ary...
