The micropolar equations of motion are developed, in a very general form, for a
mixture of fluid and solid particles. The fluid is allowed to move differently than the solids,
and the solids are modeled as a micropolar continuum. That is, the solid particles have an
additional degree of freedom...
This report is one of a series issued in cooperation with the Army-Navy-Civil Committee on aircraft design criteria under the supervision of the aeronautical board. Information reviewed and reaffirmed 1962.
A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...
In certain cases in system modeling, parameter search problems
are complicated by the availability of scanty and corrupt physical
system data and a large number of model parameters. An algorithm
using man-machine interaction is presented to attack this type
of parameter search problem with the objective of efficiency in the...
Biomechanical models have been used in designing human work environments to evaluate potential risks to workers before a work environment is constructed. In order for work environments to be modeled correctly, most biomechanical models require as input, an accurate body posture of the worker. This information can be obtained by,...
This dissertation consists of three papers on land use economics and policies. The first two papers focus primarily on local land use policies and urban development. The third paper addresses the question how environmental amenities affect households' residential choices in a metropolitan area. In the first paper, an option value...
