There are a nearly unlimited number of situations in which the
status of time-varying processes must be updated. The monitoring of
these processes usually occurs at periodic intervals. Whether the
monitoring is performed by man or machine, a decision must be made
regarding the frequency of these activities, that is,...
Experiments were designed to reveal the accuracy and precision of
four types of automatic sampler prototypes after initial testing indicated
that the single tube vibrator sampler was not drawing a complete
cross section of the seed flow in a vertical column. These experiments
compared the automatic samplers with the trier...
This thesis presents a table of dependent, mixed variables
and attributes double sampling plans, where the standard deviation
of the quality characteristic is assumed to be known, and the acceptance
number is zero for the attributes portion of the plans.
The table gives sampling plans for ten ranges of lot...
Laboratory soil tests help you develop and maintain more productive soil and increase crop production by providing information on the available nutrient content of your soil. Soil testing helps you select the correct kind and amount of fertilizer and liming material. Recommendations are based on the results of fertilizer experiments,...
A common problem in postal surveys of human populations
arises when some of the sampled people fail to respond to the questionnaire.
The problem is that the answers provided by the respondents
may not be typical of the answers the nonrespondents would
provide if these had been solicited more successfully....
The problem of predicting variate values for all individual units
in a finite population based on a sample of some of the units is Investigated.
Two prediction problems are considered: the one-stage prediction
problem where the unit variate values are directly observable for
each sample unit, and the two-stage prediction...
An inspection model is considered in which inspections are
hazardous to the device being monitored. The model is formulated as
a partially observable Markov decision process. Previous research
has determined the optimal ongoing inspection policies for a previously inspected device. In this thesis, the optimal inspection
initiation policies are investigated...
The purpose of the thesis is to synthesize the major results of a continuous
research effort directed toward new applications of high speed sampling in general and Electrooptic Sampling in particular.
Equivalent time sampling of repetitive high speed signals continues to provide significant performance enhancements for present and future generations...
Most raw product received at processing plants in Oregon is sampled to determine quality characteristics as a basis of grower payment. Raw product sampling procedures must provide the processor with a means of sampling which will be sufficiently precise to satisfy himself as well, as his growers, and thus avoid...
The sampling theorem states that any frequency bandlimited signal can be exactly reconstructed from its sampled values. Different forms of this theorem have been reviewed since 1841 up to the present time. Kramer's generalized sampling theorem has been extended to two dimensions, and the form for higher dimensions can be...
