Stud welding is a process used in the construction industry to anchor concrete slabs to underlying steel substructures . This process is highly repetitive and, thus, a good candidate for automation. A robotic device, the Studmaster , has been developed which will automate stud welding currently done in the construction of industrial buildings. This machine, currently controlled by a microcomput...

Retention of a mandibular denture can be achieved by an implant-retained or natural tooth-retained bar and stud attachment in the anterior segment of the mandible. The same design principles holds true for both implant-retained and tooth-retained methods of anchoring the bar and stud attachment. A simple and cost effective treatment for more complex implant overdenture is the concept of convent...

In this paper the maximum current carrying capability of ACAs flip chip joint is investigated based on two failure mechanisms: (1) degradation of the interface between gold stud bumps and aluminum pads; and (2) ACA swelling between chips and substrates under high current stress. For the determination of the maximum allowable current, bias stressing was applied to ACAs flip chip joint. The curre...

There are many reasons for freezing canine semen. Perhaps the most important reason is to preserve and insure the breeding potential of a dog against loss, death or infertility. This provides for the stud dog to sire puppies when he is no longer able to do so. Freezing semen also allows for the transport of genetic material both within and between countries. This obviously increases the marketi...

Although the consequences of hospital ED crowding have been studied extensively, causes are still not well understood. Throughput factors in models difficult to stud...

The title compound, a Ga(II) dimer, [Ga(2)Br(4)(C(12)H(23)P)(2)], was synthesized by reaction of GaBr(THF)(n) (THF is tetra-hydro-furan) with dicyclo-hexyl-phosphine in toluene. At 150 K the crystallographically centrosymmetric molecule exhibits disorder in which one of the two independent cyclo-hexyl groups is modelled over two sites in a 62 (1):38 (1) ratio. In d(6)-benzene solution, the comp...

We classify the possible Mumford-Tate groups of polarizable rational Hodge structures.

In this paper, a new method is proposed for calibrating a planar array of general geometry with respect to errors in location, phase and gain, even when all errors are present simultaneously (global calibration). The method requires the use of three pilot sources, which operate one at a time and from at least two different azimuth angles. Since the sources need not operate simultaneously, one o...

We prove that for abelian varieties with semistable ordinary reduction the p-adic Mazur-Tate height pairing is induced by the unit root splitting of the Hodge filtration on the first deRham cohomology.
