As human exploration of space continues, eventually sights will be set on establishing a permanent manned habitat on the surface of Mars. The success of such a base will depend on many new and developing technologies. Low mass and high energy density power production units will be of paramount importance....
Real-time, high efficiency neutron spectroscopy has, historically, been a persistent challenge in the field of radiation detection and, for the most part, has gone unsolved. The most promising method to resolve this challenge, is the boron-capture technique using an organic scintillation system (BC-523a). Detectors that utilize this method possess an...
John Wesley Powell worked actively for public land system
reform while a director of geographical and geological surveys in
the West from 1869 to 1894. Although this has won him acclaim as a
conservationist, the basis of Powell's linkage of reform with
scientific work is poorly understood.
A study of...
The purpose of this work was to design a system for measuring
the velocity of a powder actuated fastener or drivepin during penetration.
This system would provide a tool for further investigation
into drivepin penetration characteristics. The main characteristic
of interest is the instantaneous acceleration from which the forces
on...
This thesis is concerned with the problem of developing a
method to categorize probability models by their outlier properties.
There have been two such categorization methods proposed in the
literature. Neyman and Scott (1971) classify an entire family of
distributions into the outlier properties outlier-prone completely
(OPC) and outlier resistant....
Agricultural economists have devoted considerable attention to
the financial stress situation of agricultural producers. Many
studies have been conducted in various regions of the U.S. in an
attempt to better understand the causes of the problem. The costs
associated with farm financial stress imply corresponding benefits to
be realized by...
It is desirable to be able to describe an automobile mathematically
because of the large number of variables which affect automobiles'
handling characteristics and of the high cost of building prototypes.
A mathematical analysis facilitates the construction of a
few prototypes whose configurations look most promising.
Equations of motion were...
