Precision of nano-metric operations is an important issue in nano-engineering studies. Several operative parameters might affect the quality of results. The parameters of the nano world are significant but not entirely controllable. However, the geometrical and mechanical properties of micro cantilevers are completely controllable. So, controlling the sensitivity of resulting image through t la...

a common enzymatic cycle to turn the protein on and off. therefore learn how a set of proteins that regulate a wide Philadelphia, PA: W.B. Saunders (2002). variety of cellular functions uses a common structural 805 pp. $59.95 domain in order to carry out their diverse functions. The text is clearly written and atomic structures illustrate key points. A second example of a conceptual synthesis I...

In life, the paths we choose are influenced by our day-today experiences and the people we meet. Career choices are no different. As a pediatrician and academic, I am not infrequently asked how I became interested in working with the transgender community and doing academic work with this population. An openly gay man, many wrongfully assume that my interest and devotion stem from an identity a...

Parts orienting, the process of bringing parts in initially unknown orientations to a goal orientation, is an important aspect of automated assembly. Bowl feeders used in industry rely on a sequence of mechanical operations, without using sensors, to orient parts. In our work, we use partial information sensors along with mechanical operations to eliminate uncertainty in part orientation. We sh...

This paper describes an experimental very high level programming system for computer controlled mechanical assembly. AUTOPASS (AuTomated Parts Assembly System). The AUTOPASS language is oriented towards objects and assembly operations, rather than motions of mechanical assembly machines. It is intended to enable the user to concentrate on the overall assembly sequence and to program with Englis...

Anode-supported micro-tubular solid oxide fuel cell (SOFC) offers many advantages over the electrolyte and cathode-supported confgurations in terms of simplicity, reliability, and efciency. In such design, the anode substrates should possess a highly porous structure, provide active sites reaction as well as serving good mechanical strength. This structure is desired to ...

For generality, MPI collective operations support arbitrary dense communication patterns. However, in many applications where collective operations would be beneficial, only sparse communication patterns are required. This paper presents one such application: Octopus, a production-quality quantum mechanical simulation. We introduce new sparse collective operations defined on graph communicators...

Relaxation phenomena in glasses are a subject of utmost interest, as they are deeply connected with their structure and dynamics. From a theoretical point of view, mechanical relaxation allows one to get insight into the different atomic-scale processes taking place in the glassy state. Focusing on their possible applications, relaxation behavior influences the mechanical properties of metallic...
