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...

متن کاملCapital Accumulation in a Model of Growth and Creative Destruction
_________________________________________________________________________ Capital accumulation and creative destruction is modeled together with risk-averse households. The novel aspect—risk-averse households—allows to use well-known models not only for analyzing long-run growth as in the literature but also short-run fluctuations. The model remains analytically tractable due to a very convenie...
