Absfract Despite the enormous research efforts in creating new applications with MEMS, the research efforts at the backend such as packaging and assembly are relatively limited. One reason for this is the level of dimculty involved. One fundamental challenge lies in the fact that at micro-scale, micro mechanical structures are fragile and easy to break they typically will break at the micro-New...

We have been developing a novel method to program a robot, an APO (assemblyplan-from-observation) method. A human performs assembly operations in front of the APO system's TV camera. The APO system recognizes such assembly operations and generates an assembly plan to repeat the assembly operations using its robot arm. Since an important purpose of assembly operations is to achieve face contacts...

Langley Research Center developed a unique test bed for investigating the practical problems associated with the assembly of large space truss structures using robotic manipulators. The test bed is the result of an interdisciplinary e ort that encompasses the full spectrum of assembly problems|from the design of mechanisms to the development of software. This paper describes the automated struc...

stract In this paper, we propose the scheduling methodology for a multi-robot assembly cell, which is then integrated into a simulation environment. Since modeling a multi-robot assembly system is difficult and tedious, a systematic method is proposed to transfer the AND/OR product assembly graph and the domain knowledge to assembly rules. Given this rule-base knowledge, an inference engine fir...

In the context of Model Driven Architecture (MDA), most model transformation mechanisms aim for rigorously and unambiguously defined, fully automatic transformations. We argue that such techniques, even when fully mature, are not applicable in all cases of software development. These difficult cases would benefit from flexible and semi-automatic open transformations. We present a mechanism, so ...

The type II secretion system is utilized by many Gram-negative bacteria to export folded proteins to the surface and/or the extracellular environment of the cell. Although the function of the system is to move proteins from the periplasm to the outside of the cell, it is a large trans-envelope structure composed of more than a dozen different proteins present in multiple copies, including perip...

MOTIVATION In order to accelerate the finishing phase of genome assembly, especially for the whole genome shotgun approach of prokaryotic species, we have developed a software package designated prokaryotic genome assembly assistant system (PGAAS). The approach upon which PGAAS is based is to confirm the order of contigs and fill gaps between contigs through peptide links obtained by searching ...

Abstract Theoretical approaches, computer modell methods and experimental studies analyse the state behaviour of machine parts to determine changes in their properties parameters from a single synergetic position.
