1. Belmasrour, Rachid. The Distribution of Cotton Fiber Length.

Degree: PhD, Mathematics, 2010, University of New Orleans

By testing a fiber beard, certain cotton fiber length parameters can be obtained rapidly. This is the method used by the High Volume Instrument (HVI). This study is aimed to explore the approaches and obtain the inference of length distributions of HVI beard sam- ples in order to develop new methods that can help us find the distribution of original fiber lengths and further improve HVI length measurements. At first, the mathematical functions were searched for describing three different types of length distributions related to the beard method as used in HVI: cotton fiber lengths of the original fiber population before picked by the HVI Fibrosampler, fiber lengths picked by HVI Fibrosampler, and fiber beard's pro-jecting portion that is actually scanned by HVI. Eight sets of cotton samples with a wide range of fiber lengths are selected and tested on the Advanced Fiber Information System (AFIS). The measured single fiber length data is used for finding the underlying theoreti-cal length distributions, and thus can be considered as the population distributions of the cotton samples. In addition, fiber length distributions by number and by weight are dis- cussed separately. In both cases a mixture of two Weibull distributions shows a good fit to their fiber length data. To confirm the findings, Kolmogorov-Smirnov goodness-of-fit tests were conducted. Furthermore, various length parameters such as Mean Length (ML) and Upper Half Mean Length (UHML) are compared between the original distribution from the experimental data and the fitted distributions. The results of these obtained fiber length distributions are discussed by using Partial Least Squares (PLS) regression, where the dis-tribution of the original fiber length from the distribution of the projected one is estimated.

2. Wu, Yuefeng. Construction of Some Unbalanced Designs for the Partition Problem.

Degree: MS, Mathematics, 2005, University of New Orleans

In a pioneering work, Bechhofer (1954) introduced the concept of indifference-zone formulation and formulated some methodologies in the case of the problem of selecting the best normal population. In statistical literature, many vector-at-a time and unbalanced methodologies are available for the selecting the best normal population. However, the literature is not that rich for the partition problem. In this thesis, an unbalanced methodology of sampling along the lines of Mukhopadhyay and Solanky (2002) is introduced for the partition problem. A two-stage and a purely sequential procedure are introduced which take c observations from the control population from the control population for each observation from each of the non-control population. The theoretical second-order asymptotics of the two introduced procedures are derived and studied for small to moderate sample sizes via Monte Carlo simulations. The robustness of various already known procedures in the statistical literature and the ones proposed in this thesis are studied via simulation studies. An attempt has also been made to determine the optimal choice of the value of c. Advisors/Committee Members: Solanky, Tumulesh, Li, Linxiong, Watkins, Terry.
