the photocatalytic decomposition of trichloroethylene (tce) and tetrachloroethylene (pce)in water was studied. tce and pce were present in water at very low concentrations of about 15 μg/dm3. thisconcentration level corresponds to the one occasionally occurring in groundwater. results of this researchconfirmed usefulness of the photocatalytic process for successful removal of low-concentrated t...

Many owners and operators of concentrated animal feeding operations (CAFO) need to secure National Pollutant Discharge Elimination System permits from the federal or state permitting authority. Because of the expense and inconvenience of permit applications, farm groups have challenged revisions to the federal CAFO Rule as well as state regulations claiming selected provisions exceeded the auth...

In this thesis, two new models are introduced for the purposes of (i) locating sites in hillside terrain suitable for central receiver solar thermal plants and (ii) optimization of heliostat field layouts for any terrain. Additionally, optimization of heliostat canting, is presented as an application of the heliostat layout optimization model. Using the site selection model, suitable sites are ...

The interactions between the two most important colloids in milk, fat globules and casein micelles, were investigated. Mixtures of oil droplets (as a model for fat globules) and casein micelles were prepared, and their phase behavior was studied. It was found that the oil droplets and the casein micelles phase separate as a result of depletion interaction. The experimentally determined phase bo...

This research employs probit analysis to examine the selection criteria governing nonuniform application of concentrated housing code enforcement in the city of St. Louis. The study has three specific objectives: (1) to identify the goals and geographic selection criteria characteristic of St. Louis' concentrated code enforcement program during the twenty years that it was in effect; (2) to est...

This paper discusses the theory and application of learning Boolean functions that are concentrated in the Fourier domain. We first estimate the VC dimension of this function class in order to establish a small sample complexity of learning in this case. Next, we propose a computationally efficient method of empirical risk minimization, and we apply this method to the MNIST database of handwrit...
