Standard Cosmology in the DGP Brane Model
In recent years large extra dimensions which can only be probed by gravitons and eventually non-standard matter have attracted a lot of attention. These models usually yield the correct Newtonian (1/r)-potential at large distances because the gravitational field is quenched on submillimeter transverse scales. This quenching appears either due to finite extension of the transverse dimensions [1]...
متن کاملinvestigating 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...
