Comparative Evaluation Of Ethanol Yield From Htf Corn Varieties In The Whisky Production Process., Kara Marie Zoeller

Electronic Theses and Dissertations

In the whisky industry there is a balance between the desire to adhere to the traditional production process and the desire to increase profit margins. One solution that follows both stipulations is to increase the alcohol yield of a given batch of whisky. This can be achieved by utilizing high total fermentable corn which has a higher concentration of fermentable starches than other corn. HTF corn has the potential for a greater final ethanol yield. By simply using a higher quality of raw materials, the integrity of the process is maintained while allowing for an increase in output. Ten strains …

Rear Impact Crashworthiness Of A Manual Wc19 Wheelchair Occupied By A 50th Percentile Atd., Zdravko Salipur

Electronic Theses and Dissertations

For persons with disabilities, access to transportation is necessary for integration into society. The Americans with Disabilities Act (ADA) has been instrumental in assuring transportation access to individuals with disabilities for purposes of employment, education, and recreation. A substantial number of wheelchair users may not be able to transfer from their wheelchair to a motor vehicle seat during transportation. It is necessary to afford these wheelchair users the same level of safety as occupants seated in motor vehicle seats. The purpose of this study was to investigate the response of a manual wheelchair used as a motor vehicle seat, while …

Identification Of Chlorinated Solvent Sources In The Indoor Air Of Private Residences Around Hill Air Force Base, Utah, Andrew Jensen Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Volatile chlorinated solvents such as trichloroethylene (TCE), 1,2 dichloroethane (1,2 DCA), and perchloroethylene (PCE) have been identified in the indoor air of residences located near Hill Air Force Base (AFB), Utah. These vapors can originate from either volatilization of contaminates from shallow contaminated groundwater and transport into residences or from sources within the residence. The focus of the thesis was the development of a testing strategy for determining sources of TCE, 1,2 DCA, and PCE in the indoor air of residences near Hill AFB.

Eight residences were selected for this study by Hill AFB based on prior detections of TCE, …

Monitoring Tissue Engineering Using Magnetic Resonance Imaging, Huihui Xu, Shadi F. Othman, Richard L. Magin

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Assessment of tissue regeneration is essential to optimize the stages of tissue engineering (cell proliferation, tissue development and implantation). Optical and X-ray imaging have been used in tissue engineering to provide useful information, but each has limitations: for example, poor depth penetration and radiation damage. Magnetic resonance imaging (MRI) largely overcomes these restrictions, exhibits high resolution (approximately 100 μm) and can be applied both in vitro and in vivo. Recently, MRI has been used in tissue engineering to generate spatial maps of tissue relaxation times (T₁, T₂), water diffusion coefficients, and the stiffness (shear moduli) of …

Energy Efficient Geographic Routing For Wireless Sensor Networks., Gang Zhao

Electronic Theses and Dissertations

A wireless sensor network consists of a large number of low-power nodes equipped with wireless radio. For two nodes not in mutual transmission range, message exchanges need to be relayed through a series of intermediate nodes, which is a process known as multi-hop routing. The design of efficient routing protocols for dynamic network topologies is a crucial for scalable sensor networks. Geographic routing is a recently developed technique that uses locally available position information of nodes to make packet forwarding decisions. This dissertation develops a framework for energy efficient geographic routing. This framework includes a path pruning strategy by exploiting …

Focused Image Search In The Social Web., Zhiyong Zhang

Electronic Theses and Dissertations

Recently, social multimedia-sharing websites, which allow users to upload, annotate, and share online photo or video collections, have become increasingly popular. The user tags or annotations constitute the new multimedia "meta-data". We present an image search system that exploits both image textual and visual information. First, we use focused crawling and DOM Tree based web data extraction methods to extract image textual features from social networking image collections. Second, we propose the concept of visual words to handle the image's visual content for fast indexing and searching. We also develop several user friendly search options to allow users to query …

Experiences Influencing Degree Completion Articulated By Doctoral Students In Education Administration., David Lee Barnett

Electronic Theses and Dissertations

Educational literature indicates that approximately half of all doctoral students persist to degree completion. The literature indicates persistence rates among the social sciences are even lower. This study examined factors influencing doctoral student persistence in education administration programs. Tinto's theory of graduate student persistence framed four research questions: Do the demographics of doctoral students persisting to degree completion in education administration differ from those not completing their programs? Do doctoral students in education administration programs articulate experiences of academic integration as influencing their persistence? Do doctoral students in education administration programs articulate experiences of social integration as influencing their persistence? …

The Role Of Hsp90 In Pc-12 Cell Survival., Christina Blume Clark

Electronic Theses and Dissertations

The chaperone heat shock protein 90 (Hsp90) regulates physiologically and pathological cellular processes, by binding and stabilizing kinases involved in basal cellular functions and in cellular responses to stress, respectively. I hypothesize that Hsp90 binding to kinases Akt and Raf-l and to co-chaperone Cdc37 and Akt-dependent phosphorylation of Hsp90 regulate PC-12 cell survival. Hsp90 binding was inhibited using the classical Hsp90 inhibitor, Geldanamycin (GA). Disruption of Hsp90 binding by GA correlated with similar cell death at normoxia (RA) and at 0.1 % O2 sustained hypoxia (SH), suggesting that Hsp90 binding plays a role in cell survival. Indeed, GA cytotoxicity is …

Voting System Risk Assessment Via Computational Complexity Analysis, Dan S. Wallach

William & Mary Bill of Rights Journal

Any voting system must be designed to resist a variety of failures, ranging from inadvertent misconfiguration to intentional tampering. The problem with conducting analyses of these issues, particularly across widely divergent technologies, is that it is very difficult to make apples-to-apples comparisons. This paper considers the use of a standard technique used in the analysis of algorithms, namely complexity analysis with its "big-O" notation, which can provide a high-level abstraction that allows for direct comparisons across voting systems. We avoid the need for making unreliable estimates of the probability a system might be hacked or of the cost of bribing …

Origins, Composition And Distribution Of The Bees Of Cuba (Hymenoptera: Apoidea: Anthophila), Julio A. Genaro

Insecta Mundi

The origins of the Cuban bee fauna are reviewed. This fauna began to form 40 million years ago during the Proto Antilles period, through ancestors that arrived in successive invasions from adjacent continental areas. The composition of the Antillean fauna has evolved continuously over millions of years until the present time. The native bee fauna of Cuba is represented by 89 species, contained in 29 genera and 4 families. The number of genera represented per family is as follows: Colletidae (3), Halictidae (8), Megachilidae (4), and Apidae (14). The Cuban apifauna contains four principal groups with distinct biogeographic histories: endemic …

Hydrodynamic Loading Of Microcantilevers Oscillating Near Rigid Walls, Ryan C. Tung, Jana Anirban, Arvind Raman

Birck and NCN Publications

The vibrations of microcantilevers in atomic force microscopes (AFMs) or radio frequency (RF) switches are strongly influenced by the viscous hydrodynamics of the surrounding fluid in the vicinity of a rigid wall. While prior efforts to model this hydrodynamic loading have focused on squeeze film damping effects at high Knudsen and squeeze numbers, the regimes of low Knudsen and squeeze numbers are also very important for which squeeze film models need to be discarded in favor of unsteady Stokes hydrodynamics. We extend the work of Green and Sader [Phys Fluids 17, 073102 (2005); J. Appl. Phys. 98, 114913 (2005)] and …

Modeling And Simulation Of Field-Effect Biosensors (Biofets) And Their Deployment On The Nanohub, Clemens Heitzinger, Rick Kennell, Gerhard Klimeck, Norbert Mauser, Michael Mclennan, Christian Ringhofer

Other Nanotechnology Publications

Biofets (biologically active field-effect transistors) are biosensors with a semiconductor transducer. Due to recent experiments demonstrating detection by a field effect, they have gained attention as potentially fast, reliable, and low-cost biosensors for a wide range of applications. Their advantages compared to other technologies are direct, label-free, ultrasensitive, and (near) real-time operation. We have developed 2D and 3D multi-scale models for planar sensor structures and for nanowire sensors. The multi-scale models are indispensable due to the large difference in the characteristic length scales of the biosensors: the charge distribution in the biofunctionalized surface layer varies on the Angstrom length scale, …

Theoretical Determination Of Subcritical Sequent Depths For Complete And Incomplete Hydraulic Jumps In Closed Conduits Of Any Shape, Nathan John Lowe

Theses and Dissertations

In order to predict hydraulic jump characteristics for channel design, the jump height may be determined by calculating the subcritical sequent depth from momentum theory. In closed conduits, however, outlet submergence may fill the conduit entirely before the expected sequent depth is reached. This is called an incomplete or pressure jump (as opposed to a complete or free-surface jump), because pressure flow conditions prevail downstream. Since the momentum equation involves terms for the top width, area, and centroid of flow, the subcritical sequent depth is a function of the conduit shape in addition to the upstream depth and Froude number. …

Who Could Best Complement A Team Of Family Business Researchers—Scholars Down The Hall Or In Another Building?, Alex Stewart

Management Faculty Research and Publications

This study explores which fields might potentially collaborate in family business research. It compares 14 research fields for their structure of topical attention. The most convenient collaborations, such as those between entrepreneurship, family business, and strategy researchers, prove to be the most appropriate for some research purposes. However, less common collaborations, particularly with scholars from law, history, and anthropology, appear to be the most appropriate for other projects. Family and marital therapy prove to be a less promising collaborator than one might expect because of their strong skewing to familial rather than commercial topics. Correspondingly, entrepreneurship also proves to be …

Impacts Of Express Bus Service On Passenger Demand, Jeffrey M. Casello, Bruce Hellinga

Journal of Public Transportation

The Region of Waterloo, Ontario, is a rapidly-growing metropolitan area approximately 100 km west of Toronto. In 2005, the Region’s transit operator, Grand River Transit, introduced an express bus service, known as iXpress, along the central northsouth corridor of the Region. This paper explores the impact of the iXpress service on transit user costs and passenger attraction. We employ a methodology to quantify the generalized cost (including waiting time, in-vehicle and transfer times) of transit trips between key destinations in the Region before and after the implementation of iXpress. We also develop a methodology to identify those customers who benefit …

Users’ Perceptive Evaluation Of Bus Arrival Time Deviations In Stochastic Networks, Nikolaos G. Daskalakis, Anthony Stathopoulos

Journal of Public Transportation

This work is a report on research concerning transit service characteristics as seen from the users’ point of view. Users of two separate bus lines, operating in a shared/ common urban infrastructure, were interviewed at bus stops about their perception concerning headways of bus lines operation. An analysis was made regarding deviations between actual and scheduled bus arrival headway. Further statistical analysis was carried out to check factors giving rise to different perceptions. The operation of each bus line was registered, and corresponding service characteristics were compared with those perceived by the users. Based on these results, a model for …
