Active control of acoustic radiation due to discontinuities on thin beams
(Virginia Tech, 1991-04-15)
<p>Two experiments were conducted to study the active control of acoustic radiation due to discontinuities on thin beams. One experiment investigated the radiation from a clamped end condition and the other investigated ...
A study of the static to kinetic friction transition of polymers
(Virginia Tech, 1995-05-01)
<p>This study investigates the transition from static to kinetic friction for structural polymers and continues previous research conducted by Dr. N. S. Eiss, B. McCann, and R. Molique. A new test apparatus which simultaneously ...
Statistical Characterization of Vehicle and Track Interaction Using Rail Vehicle Response and Track Geometry Measurements
(Virginia Tech, 1998-06-29)
This study evaluates the dynamic interaction between rail vehicles and the track on which they travel. The measurements were analyzed in the time and frequency domain. The effects of external parameters such as the vehicle ...
Analysis of a space experimental design for high-Tc superconductive thermal bridges
(Virginia Tech, 1994-12-12)
<p>Infrared sensor satellites are used to monitor the conditions in the earth's upper atmosphere. In these systems, the electronic links connecting the cryogenically cooled infrared detectors to the significantly warmer ...
Development of a cantilever beam, capacitive sensing, skin friction gage and suppporting instrumentation for measurements
(Virginia Tech, 1993-05-15)
<p>A cantilever beam type, capacitive sensing, skin friction gage has been developed. A prototype along with supporting electronics has been constructed. The cantilever beam gage is a change of area variable capacitive ...
The design and construction of a free surface water table for the investigation of compressible-flow phenomena
(Virginia Tech, 1956-02-05)
An object-oriented class library for the creation of engineering graphs
(Virginia Tech, 1993)
Reduction of Unsteady Stator-Rotor Interaction by Trailing Edge Blowing Using MEMS Based Microvalves
(Virginia Tech, 1999-04-16)
This research performs an experimental study of a trailing edge blowing system that can adapt to variations in flow parameters and reduce the unsteady stator-rotor interaction at all engine operating conditions. The fan ...
A personal computer based instrumentation system for determining real-time dynamic torque in rotating machinery
(Virginia Tech, 1987-06-10)
<p>Measurement of dynamic/transient torques is important in the dynamic analysis of rotating machinery as it provides insight into the internal state of the machine. Existing methods are difficult to implement, results ...
