The purpose of the research has been to derive an algorithm that finds optimal aerial refueling segments (non-instantaneous) for a single aircraft deployment while also accounting for atmospheric winds. There are two decision variables: (1) Where to locate the refueling segments? (2) How much fuel to offload at each refueling segment? Later in the dissertation, a third ....

Flooding, stream bank erosion, and closures of fisheries have led to increased regulation and the use of Best Management Practices (BMPs) for stormwater management. Stormwater BMPs, such as bioretention areas, are popular among developers because they fulfill both landscape and water quality needs; however, questions on design persist. A total of four bioretention areas....

Abstract JASON, KENDRA JEANEL. Organizational Inequality in Job Promotions. (Under the direction of Dr. Donald Tomaskovic-Devey and Dr. Michael Schulman) In this study I explore the distribution of promotion opportunities between jobs in a general sample of Australian organizations. Most empirical studies of promotion have focused on a single firm, a single occupation, ....

It is well known that two of the most common microorganisms associated with food-borne illnesses are Campylobacter jejuni and Salmonella serotypes which are readily found in poultry house environments. Poultry products have been repeatedly implicated as a significant source of food-borne disease organisms. This has researchers examining methods of reducing bacteria at t....

This dissertation introduces a new online system called Expert TA. The system was developed based on the hypothesis that expressions are key elements in engineering problems and that the treatment of expressions is critical to the advancement of online systems. This dissertation identifies ergonomic problems with expression entry that Expert TA overcomes through the use....

Incorporating immersive technology into education has the potential to offer robust pedagogical situations to students that they otherwise would not be able to experience. Research suggests the incorporation of immersive technology in future chemistry labs will require utilizing a 3D graphics engine designed with VC++ and OpenGL. The design requirements, prototype, and ....

Faults, if remained undetected lead to huge financial losses. Troubleshooting faults requires analytical skills and knowledge of the system. Elementary skills help in solving common faults but faults that are infrequent or those which cannot be debugged by a consumer or even a field technician due to lack of in-depth knowledge of the system requires an experts intervent....

Caterpillars of the moth species Heliothis subflexa G. (Lepidoptera: Noctuidae) are known to feed exclusively on fruits of plants in the genus Physalis L. (Solanaceae). However, data were lacking on whether H. subflexa is constrained to feeding on a subset of the approximately 90 species in this plant genus. The purpose of this research has been to determine which Physa....

ZHAO, GANG. Finite Element Analysis and Design of Welded HSS Connections. (Under the direction of Emmett Sumner PhD., P.E.) The design specifications used for the Hollow Structural Sections (HSS) truss connections used in North America has been criticized by many structural engineers. Because of the restrictive limitations on the range of applicability, the preferred HS....

The main objective of this dissertation was to create transgenic chickens expressing â-galactosidase as a genetic marker for cell lineage studies. To generate the transgenic chickens, the replication-defective retroviral-based SNTZ vector carrying the E. coli lacZ gene encoding nuclear-localized â-galactosidase was injected into subgerminal cavity of stage X (EG & K) ....

A practical fatigue analysis methodology was developed for predicting the life of rotary-wing aircraft components. The focus of this fatigue capability was two-fold. First, to gain insight into the current life prediction methodologies and their use, and second, to be able to predict the service life of aircraft components and determine if reworked parts are suitable fo....
