Thin 1 mm or 1.5 mm Kirschners wires which as suitable for paediatric or adult hand bones have 3 sharpened end facets. The mini-Ilizarov fixator is composed of fixation units (Figure 1) for attaching the wires in to the slots (7) of slotted washers (3) and their fastening with a fixation nut (8) (Figure 2). (A) composed of slotted washers (3,7), space washer (4), bolt (5) with an axial hole and...

High flame retardant drag chain power sheathed cables are used for equipment supply, and in the outdoor environment, transmission cable needs to be fixed wall, usually along industrial route. The bridge moves, extends more frequently, supply with a sling device, because there is no such special device on market, so use of existing card fixing method leads often squeezed damaged insulation layer...

This paper demonstrates a method for tuning elastomeric microchannels for hydrophoretic separation made in poly(dimethylsiloxane) (PDMS). Uniform compressive strain is imposed on the elastomeric microchannel between two acrylic substrates by fastening the bolts. The elastomeric microchannel can change its cross-section during compression, simultaneously tuning the criterion for hydrophoretic or...

Any `–cycle, 6 6 `6 n!, can be embedded in the Pancake graph Pn, n > 3. In this paper we prove the existence of a family of maximal sets of even independent cycles with length bounded by O(n2). We introduce the new concept of Prefix– reversal Gray codes based on the independent cycles which extends the known greedy Prefix–reversal Gray code constructions considered by Zaks and Williams. We deri...

We explore which polyhedra and polyhedral complexes can be formed by folding up a planar polygonal region and fastening it with one zipper. We call the reverse process a zipper unfolding. A zipper unfolding of a polyhedron is a path cut that unfolds the polyhedron to a planar polygon; in the case of edge cuts, these are Hamiltonian unfoldings as introduced by Shephard in 1975. We show that all ...

EDICS (Engineering Design Instructional Computer Program) has proven to be a fun and intriguing means of conveying a wide variety of engineering design subjects to motivated students. The program consists of seven subjects which engineering students often have difficulty with even after completing their undergraduate studies. These subjects are: bearings, drawing and drafting, mounting of shaft...

Generally, an approximately 1% weight reduction in a 200 kg automobile improves the fuel economy by 20~26% and acceleration performance 8%. Hence, various techniques for automotive lightweighting have been developed to satisfy environmental regulations of industry. The joining dissimilar materials is critical assembling lightweight body structures, but fusion welding inapplicable owing differen...
