Chemical Oxidation Enhanced Bioremediation Of Polycyclic Aromatic Hydrocarbon Contaminated Sediments, Ian Kennedy Tiang Kwong Dieng

Theses and Dissertations

This study evaluated the effect of chemical oxidation on the bioremediation of polycyclic aromatic hydrocarbons (PAHs) contaminated sediments. Sediments were treated in sequential steps: biotreatment, chemical oxidation, and biotreatment. The first biotreatment step was initiated via addition of nutrients, microbial seeds, co-metabolites, and/or Tween 80 (surfactant). The chemical oxidation step was conducted using Fenton?s Reagent, ozonation, and peroxone (combination of ozone and hydrogen peroxide). The objective was to enhance the PAHs bioavailability via oxidation of natural organic matter and transformation of Heavy PAHs into more biodegradable compounds. Biotreatment was reestablished as a final polishing step to further degrade remaining PAHs …

Parzsweep: A Novel Parallel Algorithm For Volume Rendering Of Regular Datasets, Lakshmy Ramswamy

Theses and Dissertations

The sweep paradigm for volume rendering has previously been successfully applied with irregular grids. This thesis describes a parallel volume rendering algorithm called PARZSweep for regular grids that utilizes the sweep paradigm. The sweep paradigm is a concept where a plane sweeps the data volume parallel to the viewing direction. As the sweeping proceeds in the increasing order of z, the faces incident on the vertices are projected onto the viewing volume to constitute to the image. The sweeping ensures that all faces are projected in the correct order and the image thus obtained is very accurate in its details. …

The Evaluation Of Chemical Reaction Dynamics Within Swine-Raising Facility: Implications To Odor Evolution And Assessment Of Abatement Strategies, Andrew Joseph Wynn

Theses and Dissertations

The effectiveness was measured using water quality testing, odor assessments by a human sensory panel, and air phase measurements of hydrogen sulfide and ammonia. The results indicated that both aeration and aeration …

Wavelet-Based Volume Rendering, Pujita Pinnamaneni

Theses and Dissertations

Various biomedical technologies like CT, MRI and PET scanners provide detailed cross-sectional views of the human anatomy. The image information obtained from these scanning devices is typically represented as large data sets whose sizes vary from several hundred megabytes to about one hundred gigabytes. As these data sets cannot be stored on one's local hard drive, SDSC provides a large data repository to store such data sets. These data sets need to be accessed by researchers around the world to collaborate in their research. But the size of these data sets make them difficult to be transmitted over the current …

The Simulation System For Propagation Of Fire And Smoke, Dmitry N. Shulga

Theses and Dissertations

This work presents a solution for a real-time fire suppression control system. It also serves as a support tool that allows creation of virtual ship models and testing them against a range of representative fire scenarios. Model testing includes generating predictions faster than real time, using the simulation network model developed by Hughes Associates, Inc., their visualization, as well as interactive modification of the model settings through the user interface. In the example, the ship geometry represents ex-USS Shadwell, test area 688, imitating a submarine. Applying the designed visualization techniques to the example model revealed the ability of the system …

Emerging Technologies In Architectural Visualization: Implementation Strategies For Practice, Nethra Mettuchetty Ram Mohan

Theses and Dissertations

Representation has always been a critical component in architectural practice and representational techniques have been evolving over time. The relatively recent advent of the digital media is revolutionizing architectural representation. Digital representation techniques are proving to be a more effective means of communicating the design to the client and the collaborative project team. The techniques are advancing so rapidly that it is becoming increasingly difficult to keep in pace with the digital acceleration and utilize these representation techniques in architectural practice. There is a wide difference between what is possible using digital architectural visualization and what is implemented in practice. …

Weather's Influence On The Phenological Period Length And Yield Of Mississippi Soybeans, Sarah Kathleen Mcatee

Theses and Dissertations

The climate of Mississippi has been considered to be ideally suited for the production of soybeans. Many studies have shown the influence of weather on crops, but none that specifically attempt to pinpoint which aspects of weather have an impact on the Mississippi soybean crop. The purpose of this study was to determine what affect weather has on the phenological period length and yield of Mississippi soybeans. Data on bean phenological periods and yield used in this research were recorded as a part of soybean variety testing conducted at Delta Research and Extension Center in Stoneville, Mississippi from 1976-2000.

Comparison Study Of Cooling Fins And Chills Effectiveness In Aluminum Sand Mold Casting, Vladimir E. Kouznetsov

Graduate Research Papers

Besides proper design of gating and risering systems, there are several methods used to control and modify solidification behavior of cast alloys. Within these methods, the most widely used are local cooling aids employing cooling fins (thin segments attached to problematic areas of casting) or external chills (metal inserts placed into mold walls to accelerate heat withdrawing from potential hot spot). The later helps to promote directional solidification when traditional methods are not possible to use due to limitations related to the casting design. Despite relatively wide application in aluminum foundries, there are no specific recommendations on cooling aids parameters …
