In this presentation the audience will be: (a) introduced to the aims and objectives of the DBTechNet initiative, (b) briefed on the DBTech EXT virtual laboratory workshops (VLW), i.e. the educational and training (E&T) content which is freely available over the internet and includes vendor-neutral hands-on laboratory training sessions on key database technology topics, and (c) informed on some...

In this paper, the response of hybrid composite laminate plate reinforced by the smart wires (shape memory or the SMA wires) subjected to low velocity impact is studied. The smart wires are embedded within the layers of the composite laminate. The effect of the smart wires on contact force history, and deflection of these structures is investigated. The first-order shear deformation theory as w...

Many robotic hands have been proposed to unique designs and capabilities, focusing on sensing, actuation, control. This paper presents experimental studies a soft 3D-printed hand whose fingers are actuated by twisted coiled polymer (TCP<sub>FL</sub>) muscles, driven resistive heating, cooled water Peltier mechanism (thermoelectric cooling) for increasing the actuation frequency. The...

OBJECTIVE To determine the mechanical properties of commercially available thermodynamic wires and to classify these wires mathematically into different groups. MATERIALS AND METHODS The samples examined were 48 nickel-titanium (NiTi) alloy orthodontic wires commercially available from five manufacturers. These samples included 0.016-inch, 0.016- x 0.022-inch, 0.017- x 0.025-inch, and 0.018- ...

Coiled bodies are a special type of small round nuclear body, composed of coiled fibers and granules, especially prominent in the nucleoplasm of highly active cells (Brasch and Ochs (1992) Exp. Cell Res. 202, 211-223). Although no specific function has been assigned to coiled bodies, they contain spliceosome snRNAs and proteins, as well as the nucleolar U3 RNA-associated protein fibrillarin. In...

Coiled-coils are found in proteins throughout all three kingdoms of life. Coiled-coil domains of some proteins are almost invariant in sequence and length, betraying a structural and functional role for amino acids along the entire length of the coiled-coil. Other coiled-coils are divergent in sequence, but conserved in length, thereby functioning as molecular spacers. In this capacity, coiled-...

Coiled coils have attracted considerable interest as design templates in a wide range of applications. Successful coiled-coil design strategies therefore require a detailed understanding of coiled-coil folding. One common feature shared by coiled coils is the presence of a short autonomous helical folding unit, termed "trigger sequence," that is indispensable for folding. Detailed knowledge of ...
