1.1 This specification covers unalloyed tungsten plate, sheet, and foil.

1.2 The values stated in inch-pound units are to be regarded as the standard.

A 2-D finite point meshless model was used to simulate the heat transfer and solidification of steel in continuous casting molds to illustrate its use in metallurgy. The latent heat of the pure metal was treated using the temperature recovery method and the latent heat of the alloy was treated using...

The limitations of traditional approaches to selection problems are examined. A problemsolving strategy is presented in which decision-support and knowledge-based techniques play complementary roles. An approach to the representation of knowledge to support the problem-solving strategy is presented ...

We report a novel self-powered nanocomposite sensor composed of K_0.5Na_0.5NbO₃ (KNN) nanoparticles (NPs) and multiwalled carbon nanotubes (MW-CNTs). The KNN NPs and MW-CNTs are dispersed in polydimethylsioxane by mechanical agitation to produce a piezoelectric nanocom...

Common mode current suppression is important to grid-connected photovoltaic (PV) systems and depends strongly on the value of the parasitic capacitance between the PV panel and the ground. Some parasitic capacitance models have been proposed to evaluate the magnitude of the effective parasitic capac...
