Advanced reactor designs offer many advantages over typical Light Water Reactors (LWRs) including fast neutron capability, passive safety features, and improved performance. While the future for these reactors seems promising, operating and test experience is necessary to further validate such claims. The development of full-scale facilities has proved to be...

Advanced reactor designs offer many advantages over typical Light Water
Consider the c- sample testing problem with null hypothesis H[subscript]o : F₁(x) = ... = F[subscript]c(x), where F[subscript]j(x), j = 1 ..., c, represent
absolutely continuous distribution functions for failure distributions.
Furthermore, consider arbitrarily (right) censored samples, which
may arise from putting the (censored) experimental units on test at
different...
Some nonparametric maximum likelihood estimation procedures
are developed for the class of pairs of distributions which have proportional
failure rate functions. Special consideration is given to the
case in which the shape of the failure rate functions are assumed to
be either increasing or decreasing. Estimators of the proportionality
constant,...
The purpose of this thesis is to derive and compare asymptotic
performances of certain tests of independence, interchangeability
and equality of the distributions of_ratios Y/X for positive variates
and Y with joint c.d.f. H(x,y) of particular forms. Three bivariate
families, Morgenstern, Plackett, and Moran, are considered which permit
marginal c.d.f.'s...
Several lower tolerance limit procedures are compared with regard
to efficiency and robustness. The procedures include the nonparametric
based on a single order statistic and the maximum likelihood
estimates for complete and censored samples from parametric families
of distributions. Right-censoring is considered as an approach for
improving the robustness of...
Generalizations of the smooth goodness-of-fit test statistics,
the components of Cramer-von Mises type statistics and the
Pearson chi-square statistics are considered for censored samples.
Asymptotic efficiency comparisons are made between these
general goodness-of-fit tests for Weibull and gamma distributions
for certain parametric alternatives in the case of singly censored
samples....
The National Agricultural Statistical Service (NASS) conducts quarterly surveys for estimation of some primary commodities produced on farms and ranches. The commodities often have highly skewed distributions with a few farms producing very large amounts. NASS uses dual sampling frames comprised of the list frame for efficient stratification and the...
