Describing function theory as applied to thermal and neutronic problems

Creator:: Nassersharif, Bahram
Abstract:: Describing functions have traditionally been used to obtain the solutions of systems of ordinary differential equations. In this work the describing function concept has been extended to include nonlinear, distributed parameter partial differential equations. A three-stage solution algorithm is presented which can be applied to any nonlinear partial differential equation....

A mathematical model for differential thermal analysis

Creator:: Kaakinen, J. W.
Abstract:: A mathematical model of a differential thermal analysis (DTA) system was formulated so that influence of the various physical parameters on the DTA peak could be determined. The specific DTA apparatus simulated had cylindrical sample holes drilled into a nickel block considered to have a negligible thermal resistance, and the...

On the melting of cylinders and spheres

Creator:: Chutia, Bolindra Nath
Abstract:: In this thesis we consider boundary and initial value problems associated with the melting of homogeneous cylinders and spheres. The study includes the temperature distribution in cylinders and spheres which are perfectly insulated at the surface and subjected to a heat input respectively along the axis and at the center....

Large-strain softening of aluminum in shear at elevated temperature

Creator:: Alhajeri, Saleh N.
Abstract:: Pure aluminum deformed in torsion (shear) at elevated temperatures reaches a broad "peak" stress and then undergoes about a 17% decrease in flow stress with deformation to roughly 1-2 equivalent uniaxial strain. Beyond this strain the flow stress is approximately constant. The sources for this softening are unclear. The suggested...

Thermal characterization technique for thin dielectric films

Creator:: Indermuehle, Scott W.
Abstract:: A phase sensitive measurement technique that permits the simultaneous determination of two independent thermal properties of thin dielectric films is presented. Applying the technique results in a film's thermal diffusivity and effusivity, from which the thermal conductivity and specific heat can be calculated. The technique involves measuring a specimen's front...

Applied color processing

Creator:: Zhang, Heng
Abstract:: The quality of a digital image pipeline relies greatly on its color reproduction which should at a minimum handle the color constancy, and the final judgment of the excellence of the pipeline is made through subjective observations by humans. This dissertation addresses a few topics surrounding the color processing of...

Ultralight fabric reflux tube thermal vacuum testing

Creator:: Pauley, Keith Alan
Abstract:: Five Ultra light Fabric Reflux Tubes (UFRTs) were tested in a thermal vacuum chamber at the National Aeronautics and Space Administration's Johnson Space Center in September 1994. These test articles were design and fabricated by staff at the Pacific Northwest Laboratory, operated by Battelle Memorial Institute for the United States...
