Several research effort has been devoted to increase the performance of the relational database systems. Various types of database machines were so far proposed. Among them, shared nothing parallel database system such as Teradata, GAMMA, TANDEM are actually implemented and detail performance evaluation is undergoing. On the other hand, recently massively parallel processor like the Connection ...

To date, most modular robotic systems lack flexibility when increasing the number of modules due to their hard building blocks and rigid connection mechanisms. In order to improve adaptation to environmental changes, softness at the module level might be beneficial. However, coping with softness requires a fundamental rethinking of the way modules are built. A major challenge is to develop a co...

the present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. this new optimization concept is carried out for unbrac...

We prove that the saddle connection graph associated to any half-translation surface is $4$–hyperbolic and uniformly quasi-isometric regular countably infinite-valent tree. Consequently, not quasi-isometrically rigid. also characterise its Gromov boundary as set of straight foliations with no connections. In our arguments, we give a generalisation unicorn paths in arc which may be independent...

Origami is an ancient art form and can be divided into rigid non-rigid origami. Rigid origami suitable for the design of building structures because panels are not twisted deformed during folding process. Currently, generally built with steel. However, compared natural, non-polluting wood, steel has a high energy consumption environmental impact. Based on this situation, paper designs developab...

The aim of the paper is to analyse an exemplary bolted connection under conditions loss bearing capacity some fasteners in connection. presented tests are numerical and concern asymmetric joined elements were modelled as 3D finite elements, treated hybrid models consisting rigid heads nuts, flexible beams between them. was first preloaded according six different tensioning orders using a standa...
