Simulation Model To Evaluate Performance Of Operational Systems And Their Impact On Repair Shop Activity At A Navy Field Site, James T. Newell
Simulation Model To Evaluate Performance Of Operational Systems And Their Impact On Repair Shop Activity At A Navy Field Site, James T. Newell
Retrospective Theses and Dissertations
This paper presents the background and procedures leading to development of a simulation model to analyze the impact of certain decision variables on operational system performance and workloads as the repair facility of a typical Navy field site. The research examines the impact of maintenance support concepts, as implemented by changes in the decision variables, associated with the broader application of Automatic Test Equipment. The initial effort consisted of data collection and field site surveys which culminated in defining a work flow model illustrating typical repair facility operations. The work flow model is translated into a computer simulation model. The …
Software Quality Assurance, Edward C. Soistman
Software Quality Assurance, Edward C. Soistman
Retrospective Theses and Dissertations
The problems associated with software development and use are investigated from a management point of view. Having identified the critical aspects of effective software management, an approach is suggested for the creation and implementation of a software quality assurance program, Particular attention is focused on the concept of Life Cycle Procurement as currently utilized by the Department of Defense. The research was accomplished in two phases. The first consisted of an extensive literature search, seminar attendance and participation in several working groups assigned the responsibility for establishing software quality assurance guidelines. The second phase involved direct participation in the development …
An Introduction To The Winograd Discrete Fourier Transform, Janice S. Agnello
An Introduction To The Winograd Discrete Fourier Transform, Janice S. Agnello
Retrospective Theses and Dissertations
This paper illustrates Winograd's approach to computing the Discrete Fourier Transform (DFT). This new approach changes the DFT into a cyclic convolution of 2 sequences, and illustrates shortcuts for computing this cyclic convolution. This method is known to reduce the number of multiplies required to about 20% less than the number of multiplies used by the techniques of the Fast Fourier Transform. Three approaches are discussed, one for prime numbers, one for products of primes, and lastly one for powers of odd primes. For powers of 2 Winograd's algorithm is, in general, inefficient and best if it is not used. …
