This report results from ongoing work to develop a digital proficiency measurement architecture that includes the battle<br />
staff equipped with the Army Tactical Comm<strong>and</strong> <strong>and</strong> Control System (ATCCS). The report first examines primary dimensions<br />
of ATCCS-enabled performance, including major system capabilities, high- payoff user skills <strong>and</strong> tasks, <strong>and</strong> network<br />
management skills. It then explores how ATCCS exploitation contributes to critical staff functions, with an emphasis on<br />
integration across Battlefield Operating Systems (BOSs). The discussion includes findings on brigade versus battalion<br />
differences <strong>and</strong> digital versus analog staff processes. A family of proficiency level matrixes is presented for six major staff<br />
sections. Finally, the report discusses implications of the findings for digital proficiency measurement <strong>and</strong> after action review<br />
(AAR) procedures. Altogether the findings point to high-payoff proficiency targets, paving the way for ATCCS exploitation<br />
guidelines <strong>and</strong> analysis of measurement <strong>and</strong> AAR requirements for the Future Force. The report includes recommendations<br />
for harnessing the knowledge products.<br />

A Gamma Memory Neural Network for System Identification<br />
Motter, Mark A.; Principe, Jose C.; [1992]; 6 pp.; In English<br />

A gamma neural network topology is investigated for a system identification application. A discrete gamma memory<br />
structure is used in the input layer, providing delayed values of both the control inputs <strong>and</strong> the network output to the input<br />
layer. The discrete gamma memory structure implements a tapped dispersive delay line, with the amount of dispersion<br />
regulated by a single, adaptable parameter. The network is trained using static back propagation, but captures significant<br />
features of the system dynamics. The system dynamics identified with the network are the Mach number dynamics of the 16<br />
Foot Transonic Tunnel at <strong>NASA</strong> Langley Research Center, Hampton, Virginia. The training data spans an operating range of<br />
Mach numbers from 0.4 to 1.3.<br />

The Use of a Microcomputer Based Array Processor for Real Time Laser Velocimeter Data Processing<br />
Meyers, James F.; [1990]; 15 pp.; In English; Fifth International Symposium on Applications of Laser Techniques to Fluid<br />
Mechanics, 9-12 Jul. 1990, Lisbon, Portugal; Original contains color illustrations; No Copyright; Avail: CASI; A03, Hardcopy<br />
The application of an array processor to laser velocimeter data processing is presented. The hardware is described along<br />
with the method of parallel programming required by the array processor. A portion of the data processing program is<br />
described in detail. The increase in computational speed of a microcomputer equipped with an array processor is illustrated<br />
by comparative testing with a minicomputer.<br />

MSST2004, the Twelfth <strong>NASA</strong> Goddard / Twenty-first IEEE Conference on Mass Storage Systems <strong>and</strong> Technologies has<br />
as its focus long-term stewardship of globally-distributed storage. The increasing prevalence of e-anything brought about by<br />
widespread use of applications based, among others, on the World Wide Web, has contributed to rapid growth of online data<br />
