Dynamic transduction characterization of magnetostrictive actuators
(Virginia Tech, 1993-12-06)
The objective of this thesis is to develop an analysis approach for formulation of transduction or input/output representations for magnetostrictive actuators. This transduction model is developed through application of ...
Unsteady surface heat flux and temperature measurements
(Virginia Tech, 1993-05-19)
A fast response thin-film heat flux sensor was used to measure the time-resolved surface heat flux and temperature from a turbulent combustion flame impinging on a surface. Using the analytical semi-infinite conduction ...
A parametric study of the radiative and optical characteristics of a scanning radiometer for Earth Radiation Budget applications using the Monte-Carlo method
(Virginia Tech, 1993-08-17)
The Earth Radiation Budget Experiment (ERBE) and the Clouds and Earth's Radiant Energy System (CERES) are systems that measure the earth's radiation budget, or the difference between earth-emitted radiation and radiation ...
Neural network calibration of moderator temperature coefficient measurements in pressurized water nuclear reactors
(Virginia Tech, 1993-05-06)
<p>Neural networks have been shown to be capable of predicting the moderator temperature coefficient in a nuc1ear reactor by using the frequency response functions between the in-core neutron flux signal and the ex-core ...
Numerical inverse kinematics for a six-degree-of-freedom manipulator
(Virginia Tech, 1993-03-06)
A numerical study of equivalence in scanning thermistor bolometer radiometers for earth radiation budget applications
(Virginia Tech, 1993-02-05)
The Earth Radiation Budget Experiment (ERBE) consists of a suite of three scanning and four nonscanning radiometric instruments on each of three satellites which monitor the solar-reflected and Earth-emitted components of ...
An object-oriented, knowledge-based, non-procedural approach to multi-disciplinary, parametric, conceptual design
(Virginia Tech, 1993-07-19)
<p>The use of computers in the area of design and manufacturing is commonplace in industry. Many companies are turning to custom designed in-house software to surpass the competition. A growing number are developing ...
Jet mixing: the role of numerical flow visualization
(Virginia Tech, 1993-04-10)
Entrainment can be defined as the thickening of a shear layer in the streamwise direction due to an increase in the volume occupied by the vorticity-containing fluid. The extent to which this process occurs depends heavily ...
Development of a new shock capturing formula for pressure correction methods
(Virginia Tech, 1993-12-05)
<p>Several methods have been developed to capture shock waves in turbo machinery flows, such as Moore's pressure correction procedure and Denton's time marching procedure. The time marching procedure is traditionally used ...
Three-dimensional velocity extraction using laser Doppler vibrometry
(Virginia Tech, 1993-02-03)
<p>In the analysis of plates and beams, in-plane velocities have been assumed to be small and negligible. This was nearly an unavoidable assumption due to the fact that the in-plane velocity was near impossible to determine ...
