A brief history of X-ray control methods is presented, and
the instrumentation requirements and physiological considerations
pertaining to an automatic X-ray control system are discussed.
The latter half of the thesis describes the design and operation
of a device which will permit medical radiographs to be taken
automatically and at...
It is well known that every Banach space with a Schauder basis
is separable. However, whether the converse of the above statement
is true is not known.
It is therefore the purpose of this thesis to investigate the question
of under what conditions an arbitrary, separable, Banach space
has a...

integrated systems framework to analyze the planning
process in family businesses. The model was developed
from a literature review of family study, organizational
development, and family business research. Major
components of the family business planning process were

The thesis describes the properties of surface wind and air
temperature time series recorded at three locations on the pack ice
of the Beaufort Sea. Time series consisting of sequential one-half
hourly means were constructed for a period of approximately a year.
A diurnal fluctuation in air temperature is found...
Many species of rodents and insectivores live in subterranean burrows in soils throughout the world. The soil surface perforations of burrow entrances are often connected to complex, subsurface tunnel networks. Burrow entrances and associated subsurface tunnel networks represent a link between surface and subsurface ecological function. Anecdotal observations of surface-water...
