A new compact magnetron plasma system and its characteristics are described. The system makes it possible to carry out ion irradiation experiments at high fluxes of 1018 ions/cm2·s and to reach fluences of 1022 cm−2, with a homogeneous distributio

A data acquisition system was developed for the recording of flight test data of a Cessna 172 S general aviation aircraft. The proposed system required the ability to reliably acquire data suitable for a validation database for general aviation simul

We describe performance of an analog neural network trained to identify signatures from the AC electrical power system on the Space Shuttle Orbiter. The network is based on the Intel ETANN analog neural network and identifies various electrical equip

There is a distinct parallel between software requirements for hardware in the loop simulation and dynamic wind tunnel testing. Timing, hardware interface, and usability are key factors in overall system quality. A reconfigurable PC-Based simulation

An investigation has been conducted in the Spin Tunnel Facility at the NASA Langley Research Center to measure the pressures on the wing surfaces of a model of a Basic Training Aircraft during steady rotation. The tests were made to determine the nat

We have studied the optical beam-foil spectra of Li, Be, and Mg in the wavelength region 200–550 nm by use of a quantum efficiency calibrated monochromator at projectile energies of 210 keV for Li, 156, 256, and 356 keV for Be, and 100 keV for Mg.

Experimental beam-foil decay curves for the 4s-4p, 4p-4d, 4d-4f, and the 4p-5s transitions in Zn II are compared to decay curves synthesized from transition probabilities calculated in the numerical Coulomb approximation and either measured initial l
