Design Guidelines: A Practical Guide To Preserving The Historic, Cultural, And Architectural Heritage Of Gladewater, Texas, Conor Herterich

Electronic Theses and Dissertations

In October of 1930, Columbus Marion Joiner’s oil rig, “Daisy Bradford No. 3,” blew a gusher of oil high into the East Texas sky. The subsequent storm of economic activity that resulted from the discovery of the East Texas oilfield irrevocably changed the built environment of many small towns in the region, including Gladewater, Texas. Oil money that flowed into the city funded a flurry of building projects in the 1930s and 1940s that left an indelible mark on the landscape of Gladewater’s downtown area. Unfortunately, a lack of oversight, planning, and guidance has since led to the deterioration of …

Steric Effects Of Alkyl Ammonium Salts On The Combustion Of Exchanged Smectite Clays, Celeste A. Keith

Electronic Theses and Dissertations

Bomb calorimetry was explored as a new method for determining the cation exchange capacity (CEC) of clays. Smectite clays were modified with several alkyl ammonium salts varying in number of carbons and the spatial orientation of the carbons about the central nitrogen atom. The clays used, standards purchased from the Source Clay Repository, have CECs of 44, 80, 88, and 120 meq/100 g. Theoretically, the combustion energy of the organo-clays should be approximately the same for each salt.

Evaluation Of Using The Bootstrap Procedure To Estimate The Population Variance, Nghia Trong Nguyen

Electronic Theses and Dissertations

The bootstrap procedure is widely used in nonparametric statistics to generate an empirical sampling distribution from a given sample data set for a statistic of interest. Generally, the results are good for location parameters such as population mean, median, and even for estimating a population correlation. However, the results for a population variance, which is a spread parameter, are not as good due to the resampling nature of the bootstrap method. Bootstrap samples are constructed using sampling with replacement; consequently, groups of observations with zero variance manifest in these samples. As a result, a bootstrap variance estimator will carry a …
