The Music Muse
(Virginia Tech, 1996-11-01)
Ever wonder why two people can sing the same note with the same loudness, but sound completely different? Middle C is middle C no matter who sings it, yet for some reason Lucianno Pavarotti1s middle C sounds richer and ...
Computer Aided Analysis of Smoke Stack Designs
(Virginia Tech, 1996-09-01)
The purpose of this research is to analyze the statics and dynamics of steel smoke stacks subject to excitation by aerodynamic forces. The wind loads experienced by smoke stacks arise from various phenomenon, the most ...
Application of the Filtered-X LMS Algorithm for Disturbance Rejection in Time-Periodic Systems
(Virginia Tech, 1996-05-03)
Extensive disturbance rejection methods have been established for time-invariant systems. However, the development of these techniques has not focused on application to time-periodic systems in particular until recently. ...
Ballistic Impact Resistance of Graphite Epoxy Composites With Shape Memory Alloy and Extended Chain Polyethylene Spectra Hybrid Components
(Virginia Tech, 1996-12-09)
Graphite epoxy composites lack effective mechanisms for absorbing local impact energy often resulting in penetration and a structural strength reduction. The effect of adding small amounts of two types of high strain ...
A pneumatic conveying powder delivery system for continuously heterogeneous material deposition in solid freeform fabrication
(Virginia Tech, 1996-07-05)
<p>Great improvements are continuously being made in the solid free form fabrication (SFF) industry in terms of processes and materials. Fully functional parts are being created directly with little, if any, finishing. ...
A computational study of the 3D flow and performance of a vaned radial diffuser
(Virginia Tech, 1996-08-14)
<p>A computational study was performed on a vaned radial diffuser using the MEFP (The Moore Elliptic Flow Program) flow code. The vaned diffuser studied by Dalbert et al. was chosen as a test case for this thesis. The ...
Thermal characterization of honeycomb core sandwich structures
(Virginia Tech, 1996-03-21)
An experimental investigation of the turbulent flow in a closed compound channel
(Virginia Tech, 1996-02-05)
<p>A three-component laser Doppler anemometer was used to measure the fully developed, turbulent flow in a closed, symmetric, smooth-wall compound channel. Measurements were made across one quadrant of the cross-section ...
Development of the second-generation IMTS (Intelligent Monitoring and Trending System) and WOT (Wizard of Tech) expert system for rotating machinery
(Virginia Tech, 1996)
IMTS and WOT form a PC-based hardware and software system designed to continuously monitor large numbers of rotating machinery, evaluate each machine's condition through a series of user-definable standards, and alert ...
Neural network estimation of disturbance growth and flow field structure of spatially excited jets
(Virginia Tech, 1996-06-15)
<p>Neural networks were applied to the estimation problem consisting of identifying both nearfield and quasi-farfield flow structures of a jet undergoing spatial mode excitation. The evolution of disturbances introduced ...
