We present a method for the solution of transient flow in a multi-port fluid device with arbitrary geometry. The method is applicable to fluid devices where the fluid motion is primarily inviscid throughout the volume, but locally near a device port

This study describes a lumped-element model for a pneumatically actuated, diaphragm-driven pump. The pump was developed to dispense molten metal for automotive electronic circuit manufacturing. In place of a CFD analysis, which proved to involve exce

A single element of a gamma-ray imaging system, based on fast inorganic scintillation materials, is discussed in the context of the ranged sensing of high explosives and other organic materials, as enabled by an interrogating pulsed 14 MeV neutron so

In order to further enable the deployment of nuclear radiation imaging instruments, one can include the directional information of the products of a radiation’s interaction. In this paper, we quantify the degree of improvement that can be achieved

This paper derives a closed-form expression for Green’s function of the three-dimensional Helmholtz scalar wave equation in an anisotropic halfspace. The boundary conditions are of either the homog...

When the di- or trimethylamine dehydrogenases (trimethylamine:(acceptor) oxidoreductase (demethylating), EC 1.5.99.7) of certain methylotrophic bacteria are reduced by two electrons with substrate unusual EPR signals arise at g = 2 and g = 4 (Steenka

A characterization of triplet EPR spectra in terms of the eight phenomenological parameters of the spin Hamiltonian is given. Closed-form solutions for the three possible resonant fields between triplet energy levels are presented, and thus the calcu
