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...

Plasmid pRN1 from Sulfolobus islandicus REN1H1 is believed to replicate by a rolling circle mechanism but its origin and mechanism of replication are not well understood. We sought to create minimal expression vectors based on pRN1 that would be useful for heterologous gene expression in S. acidocaldarius, and in the process improve our understanding of the mechanism of replication. We construc...

To represent real m-dimensional vectors, a positional vector system given by non-singular matrix M ∈ ℤm×m and digit set Ɗ ⊂ ℤm is used. If m = 1, the coincides with well known numeration used to numbers. We study some properties of systems which are transformable from case 1 higher dimensions. focus on an algorithm for parallel addition allowing eventually periodic representation vectors ration...
