A two-dimensional nonlinear inverse fluid-structure interaction problem for a curvilinear elastic hydrofoil is considered. A cavity formed behind the foil is modeled according to the single-spiral-vortex model by Tulin. The fluid-structure problem is decoupled by the method of successive approximations. For the cavitation problem, the foil is modeled as a polygon. The method of conformal mappin...

We propose an ILP system FOIL-I, which induces logic programs by a top-down method from incomplete samples. An incomplete sample is constituted by some of positive examples and negative examples on a nite domain. FOIL-I has an evaluation function to estimate candidate de nitions, the function which is composition of an information-based function and an encoding complexity measure. FOILI uses a ...

The limiting uncertainty in recent high accuracy measurements of the mass attenuation coefficient is the measurement of the integrated column density. An improvement in the design of the absorption foil holder is described which reduces the integrated column density uncertainty. The new design allows the edges of the foil to be more accurately mapped by the X-ray beam by reducing the largest so...

Vol. 37 No. 5 • May 2012 • P&T® 261 mivacurium following a sales visit by a pharmaceutical representative. The carton of mivacurium was delivered to the pharmacy and was placed in stock next to metronidazole. Both products were packaged in foil overwraps. Before the error occurred, metronidazole had been the only foil-wrapped, premixed solution in the pharmacy; miva curium was not on the formul...

From last 50 years, electron beam therapy has an important radiation therapy modality. The electron beam from the LINAC is of size ∼ 2 mm, whereas the size required for actual treatment is usually larger than 2 × 2 cm up to 25 × 25 cm at the isocenter. In the present work, it is proposed to use dual scattering foil system for production of clinical electron beam. The foils for 6 to 20 MeV elect...

The accumulation of defects, and in particular He bubbles, can have significant implications for the performance of materials exposed to the plasma in magnetic-confinement nuclear fusion reactors. Some of the most promising candidates for deployment into such environments are nanocrystalline materials as the engineering of grain boundary density offers the possibility of tailoring their radiati...

A new type of infrared imaging bolometer, known as the infrared imaging video bolometer ~IRVB! has been under development at the National Institute of Fusion Science ~NIFS! over the last year. A prototype of this diagnostic has been designed and constructed at NIFS and installed on the large helical device ~LHD! and successfully operated. This diagnostic utilizes a 6639030.001 mm gold foil moun...

Compliant foil gas lubricated bearings are used for the support of light loads in the order of few kilograms at high speeds, in the order of 50,000 RPM. The stiffness of the foil bearings depends both on the stiffness of the compliant foil and on the lubricating gas film. The stiffness of the bearings plays a crucial role in the stable operation of the supported rotor over a range of speeds. Th...

This paper describes the properties of nanocrystalline silver products (Acticoat) and their applications and examines available evidence supporting their use in wound management. Acticoat utilizes nanotechnology to release nanocrystalline silver crystals. Acticoat releases 30 times less silver cations than silversulfadiazine cream or 0.5% silver nitrate solution but more of the silver released ...
