Estimations for the Separation Number of a Polynomial System
This paper is devoted to the study of the separation number of a polynomial system f : C → C defining a zero-dimensional nonsingular variety. The separation number of f is defined by sep(f) = min ‖x− y‖ where the minimum is taken for x 6= y ∈ C with f(x) = f(y) = 0. In the case of a single variable polynomial f(x) = ad ∏d i=1(x − ri) various lower bounds for sep(f) have been proved and can be f...

15 صفحه اولinvestigating 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...
