recent developments in the area of smart structures indicate that variable geometry / stiffness truss network is of fundamental importance in designing smart transformable structures and systems for space applications. this paper presents the conceptual design and dynamic modeling of a cooperative re-configurabel dual-arm robotic structure called dual-arm cam-lock manipulator. the manipulator i...

Structures enabling transformability of buildings, components and materials at different levels gain significance in view a sustainable built environment. Such structures are capable obtaining shapes response to varying functional, environmental or loading conditions. Certain limitations classic tensegrity scissor-like structures, applied so far an architectural engineering context, attributed ...

A single-crystal to single-crystal transformable coordination polymer compound was hydrothermally synthesized. The structural rearrangement is induced by selecting a ligand that contains both strong and weaker coordinating groups. Both hydrated and dehydrated structures were determined by single crystal X-ray analysis.

We describe an approach to the derivation of correct algorithms on tree-based pointer structures. The approach is based on enriching trees in a way that allows us to model commonly-used pointer manipulations on tree structures. We provide rules which allow recursive functions on trees to be transformed into imperative algorithms on enriched trees. In addition, we provide rules which allow algor...

Increase in the operational functionality of space technology leads to necessity creating large-sized transformable systems. The development adequate models which are used computational experiments simulate opening structures is great importance. Significant progress has been made field antennas: ratio mass reflector its working area decreased 0.5–1.5 kg/m 2 . Despite significant achieved desig...
