Optimizing The Space Transportation Information Network: A Training Model For An Innovative Project At Nasa Glenn Research Center, Jeff Rybak

All-Inclusive List of Electronic Theses and Dissertations

The Space Transportation Information Network (STIN) was developed to solve the challenge of managing a geographically disparate NASA program. By its nature, this "enterprise information portal" enhances communication, saves time, and retains expertise as a form-driven knowledge management data base. However, for the Revolutionary Turbine Accelerator Project (RTA) led by the NASA Glenn Research Center, a comprehensive STIN training program, designed specifically for RTA, had never been instituted. To help optimize STIN for this population, a training intervention model was designed and developed to clarify the purpose, policy, and technical usability of STIN. As the front-end to the training development …

Spatial Frequency Response Of Acrylamide Based Holographic Photopolymer, Raghavendra Jallapuram, Izabela Naydenova, Vincent Toal, Suzanne Martin, Robert Howard

Conference Papers

It has been shown that photopolymers are useful in holographic optical elements [1] and holographic interferometry [2]. However, the list of potential applications increases greatly if reflection holography is possible. Reflection holography requires a material that has the potential to record high spatial frequencies. Here we studied the spatial frequency response of an acrylamide based dye sensitized holographic photopolymer. We have investigated the effect of molecular weight of the binder and concentration of crosslinking monomer on diffusion using real time monitoring of the holographic grating formation. The effect of uniform pre-exposure on diffusion was also investigated. We have also demonstrated …

Fiducial Predictive Densities And Econometric Duration Analysis, Zhenlin Yang

Research Collection School Of Economics

In this article, we propose using fiducial predictive density (FPD) as a density estimate, which leads naturally to estimators of survivor and hazard functions and provides a simple way of constructing shortest prediction intervals. This approach is studied in detail in the context of two flexible duration models proposed in this paper, namely the trans-normal and trans-exponential families, by presenting the FPDs, their basic properties, their Bayesian correspondence and their applications in econometric duration analysis. Empirical evidences show that the FPD method provides better estimates of survivor and hazard functions, particularly the latter, than does the usual maximum likelihood method. …

Divided We Fall: The Federal Government Confronts The Digital Divide, Charmaine Jackson

Journal of Student Financial Aid

This research examines the potential consequences for higher education access if the U.S. Department of Education continues to move forward with its technology plan for financial aid delivery. More specifically, it explores how the transition of Federal Student Aid (formerly Student Financial Assistance) toward a Web-based financial aid application process will affect college applicants'particularly low-income students who often lack access to technology. Using a national data set of financial aid applicants, discriminant analyses (several stepwise) are conducted on selected demographic variables to ascertain the potential impact of this migration.

Preserving Conformance For Gcra Regulated Flows, Deryck Hong

Theses

Traffic policing/shaping has been employed at the edge of networks to ensure proper provisioning of network resources and Quality of Service (QoS) guarantees. As shown in this thesis, however, network flows that have been regulated at the network edge based on traffic descriptors, e.g., GCRA, may still become non-conforming in the network core, depending on the packet scheduling algorithm used. Two supplemental schemes to scheduling algorithms are proposed and analyzed in this thesis to ensure conformance for GCRA regulated flows. The first scheme is to add an additional traffic regulator to shape the traffic more aggressively than required constraints before …

Implementing Software Engineering Practices In Small Industry With A Focus On Requirements Elicitation, James Clifford Fleming

Graduate Theses, Dissertations, and Problem Reports (ETD)

I have been involved in small industry for 33 years and I have seen how the evolution of computers and software has affected small companies striving to grow in their market place by trying to take advantage of an evolving technology. Many times an individual is assigned the task of developing software to fit the company's needs and begins the process without any formal training in the practices of Software Engineering. My Thesis will discuss my evolving skills, gained through my Masters in Software Engineering degree work, as a Software Engineer and how I have been able to implement proper …

Evaluation Of Concrete Median Barrier Delineation Under Poor Visibility Conditions, Kari A. French

Graduate Theses, Dissertations, and Problem Reports (ETD)

A nationwide survey, durability test, and visibility test were conducted for concrete median barrier delineation. PENNDOT was encountering with delineators becoming detached due to harsh conditions in the roadside areas, as well as visibility problems in spot locations prone to fog. From the results of the research it was recommended that in areas prone to poor visibility conditions, PENNDOT consider decreasing the longitudinal spacing and providing delineation lower on the barrier than shown in the standards. With respect to the durability, in instances where the "peel-n-stick" delineators are comparable in price to obtaining the delineator and adhesive separately, that special …

Ersatz, George M. Horton Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

My work attempts to develop the relationship between optical and formal painting traditions in modernism via the literal surface of the painting and the object or objects represented. They are arranged to create an effect of simultaneous emergence and dissolution. They represent the falsely temporal aspects of the perceived world, the concretization of which only exists in the mind of the viewer. This thesis statement will address issues of surface and illusionism in modern pictorial theory and the importance of perception verses objectification. In addition I will discuss the subject matter, composition, and techniques employed to create the works. I …

Characterization Of In-Use Emissions From On-Highway Heavy-Duty Diesel Engines, Mohan Krishnamurthy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Class-8 trucks with GVWR of 80,000 lbs were tested on different driving routes and in-use brake-specific emissions of NOx and CO2 data were collected using the West Virginia University's Mobile Emissions Measurement System (MEMS). An uncertainty analysis was performed on the MEMS and it was determined the maximum possible error in the measurement of brake-specific emissions of NOx was 8% and CO2 was 6%.;A modal analysis indicated that the cruise mode comprised 70% of the time that the vehicle spent in the Not-to-Exceed (NTE) zone while the acceleration and deceleration modes about 20% and 10% respectively.;In order to reduce the …

Evaluation Of Performance Graded Asphalt Binder Equipment And Testing Protocol, Michael E. Pumphrey

Graduate Theses, Dissertations, and Problem Reports (ETD)

The testing and grading of asphalt cement has progressively changed to meet the demanding needs for quality hot mix asphalt pavements. From October 1987 through March 1993, the Strategic Highway Research Program (SHRP) conducted a {dollar}50 million research effort to improve asphalt pavement technology. The research led to the development of the Superpave(TM) mix design system (Superior Performing Asphalt Pavements) and the Performance Graded (PG) asphalt binder tests and specifications. The Performance Graded asphalt binder specifications were developed to address the shortcomings of the previous asphalt grading systems.;The objective of this research was to critically evaluate the SHRP performance graded …

Comparison Of Classification Methods For Perspiration-Based Liveness Algorithm, Sujan T. V. Parthasaradhi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the modern world there is a need for security. Biometric technologies provide a means for providing this security. Of the many different available biometric technologies, fingerprint recognition is the most popular. As with all security measures, biometric devices may be subject to attacks on the system. Fingerprint scanners may be susceptible to spoofing using artificial materials, or in the worst case, dismembered fingers. Liveness, i.e. to determine whether the introduced biometric is coming from a live source, has been suggested as a means to circumvent attacks that use spoof fingers. It has been shown that water based casting materials …

Potential Field Theory And Its Applications To Classical Mechanical Problems, Shannon Rae Stillwagon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Advances in many scientific fields are expected to come from work in nanotechnology. Engineering at nano-scales presents novel problems that classical mechanics cannot solve. Many engineers are uncomfortable designing at this level because classical or continuum mechanics does not apply and quantum mechanics is said to apply in a tangible way. There are unique opportunities to contribute to the design, controls, and analysis of systems that are particularly suited to mechanical engineering. Within the derivations of classical mechanics are assumptions that limit its use to bulk engineering. These assumptions are examined to determine what principles can be extended to smaller …

Effect Of Rate Of Sumping On Fragmentation Process In Laboratory Rotary Cutting Simulator, Muralidharan Venkataraman

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study was done to examine the fragmentation process and to improve sumping. Research has demonstrated that specific energy and specific respirable dust must be kept minimum to produce the optimum parameters of the rock/coal breakage process and to attain maximum sumping. There are three major elements affecting the efficiency of the cutting head namely: (1) Geometry and size of the cutting tool, (2) Geometry of the drum and lacing and arrangements of the tools on the drum and (3) Effect of rate of advance/dynamic impacts. The emphasis is made on the rate of advance utilizing a miniature rotary cutting …

Alkaline Durability Tests For E-Glass/Vinyl Ester-Reinforced Polymer With Nanoclay, Shu-Kai Yeh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Two kinds of GFRP (glass fiber reinforced plastics) composite materials were prepared and used in this study. One was E-glass/vinyl ester glass fiber reinforced polymer (plain GFRP) and the other was nano-GFRP prepared with the addition of 1 wt% of CloisiteRTM 10A nanoclay. These samples were aged in an alkaline solution (pH = 13.2) with 3560N (800-lbs), 2225N (500-lbs) and 885N (200-lbs) of sustained load, which were 50%, 31% and 12.5% of the tensile strength, respectively. Time to failure or tensile strength reduction was measured and used to determine durability of the samples in terms of Aging Index, which was …

Hybrid Neural Networks Models For A Membrane Reactor, Mohammed Al-Yemni

Graduate Theses, Dissertations, and Problem Reports (ETD)

Artificial neural networks (ANN) have become an established discipline and have gained extensive interest within chemical engineering. In recent years, research effort has focused on the use of "hybrid artificial neural networks" (HANN) models that combine both the deterministic and the ANN elements. Several methods have been proposed for combining ANN with first principle relations. In this thesis, a new hybrid scheme, which is similar to that developed by Kasprow for a space-independent and time-dependent fed-batch microbial reactor, was developed for a space-dependent steady-state enzymatic reactor. This scheme combines ANN with mass balances and assumed rate expressions. It was shown …

National Survey Of Psychological Practices Across Rural And Urban Communities, Craig M. Helbok

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this study was to examine potential differences in the practice of psychology across urban and rural communities. The review of the rural literature suggests that psychologists in rural areas are likely to encounter numerous ethical dilemmas and problems that are related specifically to the characteristics of such communities. To date, however, much of this literature has been based on theory and the individual experiences of practitioners. This study sought to quantify any differences in the practice of psychology across communities for such ethical issues as multiple relationships, competency, burnout, confidentiality, and visibility in the community. A survey …

Censusing And Modeling The Dynamics Of A Population Of Eastern Hemlock (Tsuga Canadensis L.) Using Remote Sensing, W. Robert Lamar

Graduate Theses, Dissertations, and Problem Reports (ETD)

A population of eastern hemlock (Tsuga canadensis L.) was censused from the ground using traditional field methods and from the air using large scale, high-resolution, aerial imagery in the early spring of 1997, 1998 and 1999. A manual crown survey map of the population, prepared from aerial imagery, was compared to a traditional field census. Over 60% of the individuals measured on the ground were not detected in the aerial census. Tree size, crown density and crown position all played roles in determining a crown's visibility from the air. Nearly all large, upper canopy hemlocks were visible in the aerial …

Empirical Development Of A Scale Of Patience, Kenneth C. Dudley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Patience is a construct not directly studied in the literature. Studies in the psychological literature have typically spoken of patience only as the converse of impatience. The assumption of these studies is that patience exists in the absence of impatience. However, other research proposes a multidimensional model of patience based on qualitative studies. It follows from the multidimensional model that patience exists on a continuum with the potential for different levels or amounts of patience across different situations. The purpose of this study was to develop an objective measure of patience.;To develop a measure of patience an item pool was …
