Faculty Publications

The Mars Odyssey Gamma Ray Spectrometer Suite has yielded global chemical information for Mars. In this work, we establish regions of unusual chemical composition relative to average Mars primarily on the basis of Ca, Cl, Fe, H, K, Si, and Th. Using data from Mars Odyssey; the Mars Exploration Rovers; the Mars Reconnaissance Orbiter Imaging; and 3.5 cm and 1.35 cm radar observations from Earth, we examine a chemically striking ≈2.E6 km2 region and find it to overlap significantly with a radar Stealth region on Mars. It is remarkably enriched in Cl and depleted in Fe and Si (along with …

Creation And Implementation Plan For A Sales Engineering Minor At California Polytechnic University, San Luis Obispo, Joshua M. Checkis

Biomedical Engineering

The profession of Sales Engineering (S.E.) offers engineers a unique opportunity to fuse their technical background with communication and business skills in order to seek a rewarding alternative to the typical engineering career path. The shortfall of this niche industry is the lack of formal academic programs that seek to develop the skills necessary to prepare engineers for the field. At this time only two sales engineering minors exist in the nation, one at Iowa State University and the other at the University of Florida. The process for this senior project was to clearly identify the scope of a competitive …

The Behavior Of Novae Light Curves Before Eruption, Andrew C. Collazzi, Bradley E. Schaefer, Limin Xiao, Ashley Pagnotta, Peter Kroll, Klaus Löchel, Arne A. Henden

Faculty Publications

In 1975, E. R. Robinson conducted the hallmark study of the behavior of classical nova light curves before eruption, and this work has now become part of the standard knowledge of novae. He made three points: 5 out of 11 novae showed pre-eruption rises in the years before eruption, one nova (V446 Her) showed drastic changes in the variability across eruptions, and all but one of the novae (excepting BT Mon) have the same quiescent magnitudes before and after the outburst. This work has not been tested since it came out. We have now tested these results by going back …

Faculty Perceptions Of Faculty Evaluation Programs At Selected Private Colleges/Universities In The Southeast United States, Jeffrey L. Rector

Masters Theses and Doctoral Dissertations

This study was conducted to determine the effectiveness of the faculty performance appraisal programs at the participating institutions. Faculty perception, regarding the effectiveness of the faculty evaluation appraisal program at their institution can be an important part of assessing the program itself. The study attempted to identify whether or not faculty members perceive that faculty performance appraisal is effective? Institutions continue to have difficulty in implementing a successful faculty performance appraisal program (Cashin, 1978). This difficulty and the need for institutions to implement effective faculty performance appraisal programs were the rationale for this study. Through analysis of the appraisal programs …

Sonic Boom Prediction Methods Using Feature-Based Adaptation Of Unstructured Meshes, Jacob Chackasseril Varghese

Masters Theses and Doctoral Dissertations

This study examines the improvement of near-field sonic boom prediction of an inviscid supersonic configuration using two grid generation refinement procedures. The first method uses P_HUGG, a parallel hierarchical Cartesian mesh generation algorithm to generate a volume mesh, with the solution-based mesh adaptation capability of P_HUGG being exploited. The mesh quality was improved using P_OPT, a parallel optimization-based mesh-smoothing program. In the second method, the commercially-available software POINTWISE™ is used for volume mesh generation. Then, P_REFINE, a parallel subdivision refinement code, is used t o adaptively refine the mesh. The effectiveness of capturing far field shocks was examined using TENASI, …

The Role Of Is Project Critical Success Factors: A Revelatory Case, Cecil Eng Huang Chua, Wee-Kiat Lim

CCX Research

Research in Critical Success Factors (CSFs) of Enterprise Systems (ES) projects has identified numerous practitioner governance mechanisms for ensuring project success. However, such research has not developed a theory of why certain critical success factors encourage project success. Our research develops such theory on a case study where even though the levels of several critical success factors were weak, the project nevertheless succeeded. Specifically, the logistics ES project succeeded even though there was (1) only marginal top management support, (2) low key user commitment, and (3) change management, training and other critical aspects of user management and communication were not …

The research was conducted in a high school classroom in which elements of engineering design were taught in a technology education context to eleventh-grade student from diverse academic backgrounds (measured by grade point average [GPA]). Participant motivation was assessed by the California Measure of Mental Motivation (CM3). The CM3 measures student motivation to apply critical thinking skills and reasoning to solve problems in five subscales: mental focus, learning orientation, creative problem solving, cognitive integrity, and …

Empirical Mode Decomposition Operator For Dewowing Gpr Data, Bradley M. Battista, Adrian Addison, Camelia C. Knapp

Faculty Publications

Signal processing tools available to ground penetrating radar data used for shallow subsurface imaging and hydrogeophysical parameter estimation are significantly handled using the same tools available to seismic reflection data. Overall, the same tools produce interpretable images from both data types, but particular noise (wow noise) in electromagnetic data must be removed before stable and accurate quantitative results can be produced. Wow noise is an inherent, nonlinear electromagnetic interference and a significant component of GPR data. Further, the nonlinear and non-stationary nature of wow noise provides a strong argument for preprocessing radar traces with time-domain operators. Time-domain operators designed for …

Heme Reversibly Damps Period2 Rhythms In Mouse Suprachiasmatic Nucleus Explants, C. J. Guenthner, David Bickar, Mary E. Harrington

Psychology: Faculty Publications

The hypothalamic suprachiasmatic nucleus (SCN), which in mammals serves as the master circadian pacemaker by synchronizing autonomous clocks in peripheral tissues, is composed of coupled single-cell oscillators that are driven by interlocking positive/negative transcriptional/translational feedback loops. Several studies have suggested that heme, a common prosthetic group that is synthesized and degraded in a circadian manner in the SCN, may modulate the function of several feedback loop components, including the REV-ERB nuclear receptors and PERIOD2 (PER2). We found that ferric heme (hemin, 3-100 μM) dose-dependently and reversibly damped luminescence rhythms in SCN explants from mice expressing a PER2::LUCIFERASE (PER2::LUC) fusion protein. …

Manganese Flux Across The Blood-Brain Barrier, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Manganese (Mn) is essential for brain growth and metabolism, but in excess can be a neurotoxicant. The chemical form (species) of Mn influences its kinetics and toxicity. Significant Mn species entering the brain are the Mn²⁺ ion and Mn citrate which, along with Mn transferrin, enter the brain by carrier-mediated processes. Although the divalent metal transporter (DMT-1) was suggested to be a candidate for brain Mn uptake, brain Mn influx was not different in Belgrade rats, which do not express functional DMT-1, compared to controls. Brain Mn influx was not sodium dependent or dependent on ATP hydrolysis, but was …

Identification And Genotyping Of Bacteria From Paired Vaginal And Rectal Samples From Pregnant Women Indicates Similarity Between Vaginal And Rectal Microflora, Nabil Abdullah El Aila, Inge Tency, Geert Claeys, Hans Verstraelen, Bart Saerens, Guido Lopes Dos Santos Santiago, Ellen De Backer, Piet Cools, Marleen Temmerman, Rita Verhelst

Obstetrics and Gynaecology, East Africa

Background: The vaginal microflora is important for maintaining vaginal health and preventing infections of the reproductive tract. The rectum has been suggested as the major source for the colonisation of the vaginal econiche.

Methods: To establish whether the rectum can serve as a possible bacterial reservoir for colonisation of the vaginal econiche, we cultured vaginal and rectal specimens from pregnant women at 35-37 weeks of gestation, identified the isolates to the species level with tRNA intergenic length polymorphism analysis (tDNA-PCR) and genotyped the isolates for those subjects from which the same species was isolated simultaneously vaginally and rectally, by RAPD-analysis. …

A Bandwidth Aware Modification To The Dsr Routing Protocol For Wireless Mesh Networks, Mustafa Ramadhan, Mark Davis

Conference papers

This work proposes a bandwidth aware cross-layer modification to the DSR routing protocol. We include the Access Efficiency Factor (AEF) parameter in addition to the hop-count in the routing discovery mechanism. AEF is a measure to the local availability of bandwidth at a node. Employing the AEF as a metric in the routing discovery mechanism attempts to avoid routing through a congested area in the network. In this modification, we impose a limit on the hop-count in order to control the delay time in the network. The path selection procedure operates by finding a path with the highest minimum AEF …

The Ecology Of The Peaks Of Otter Salamander (Plethodon Hubrichti) In Sympatry With The Eastern Red-Backed Salamander (Plethodon Cinereus), Norman Reichenbach, Andrew Kniowski

Faculty Publications and Presentations

The Peaks of Otter Salamander, Plethodon hubrichti, is found along a 19 km length of the Blue Ridge Mountains, Virginia, USA, often in sympatry with the Eastern Red-backed Salamander, P. cinereus. In a sympatric area of Bedford County, Virginia, we conducted a mark-recapture study on a 10 × 10 m site. Surface densities of salamanders increased as the number of days without precipitation prior to a collection event increased. This suggests vertical movements in response to surface moisture. When salamanders returned to the surface after rain, individuals appeared to “shuffle” between rocks and likely, leaf litter. That is, we were …

Ict Usage In Microfinance Institutions In Uganda, Joseph Kaumba Ssewanyana

The African Journal of Information Systems

Microfinance institutions (MFIs) are always often faced with high operating costs to provide financial services to the poor people and Small and Medium Enterprises. Information and Communication Technologies (ICTs) has been found to promote the dual objective of microfinance - sustainability and outreach to the poor people. Using a quantitative survey and descriptive research approach, this paper has established the extent to which ICT has been used in the microfinance institutions in Uganda. Despite the barriers, ICT usage in MFIs has been on the rise; and different applications and technologies have been adopted by some MFIs to control costs, create …

Deception Analysis In Interpersonal Communication, Loren E. Schwarzwalter

Theses and Dissertations

The art of magic reigns as the premiere form of entertainment made possible through the strategic means of deception. An untrained individual (civilian) who desires personal gain at the expense of others, however, may use the same strategic gimmicks and manipulations that magicians employ. This study considered the theatrical elements used by magicians during the performance of magic but in an interpersonal civilian context. In order to examine civilian use of the premeditated theatrical elements, and to determine their presence in deceptive interpersonal communication, this study examined low versus high self-monitors and male versus female genders.

The 2009 Personal Firewall Robustness Evaluation, Ken Pydayya, Peter Hannay, Patryk Szewczyk

Australian Information Security Management Conference

The evolution of the internet as a platform for commerce, banking, general information and personal communications has resulted in a situation where many individuals who may not have previously required internet access now require this connectivity as part of their everyday lives. In addition to this the widespread adoption of mobile broadband has lead to an increasing number of individuals having public facing IP addresses with no firewall appliances present. This situation has dramatically increased reliance on personal firewalls as the first and often last defence against intruders (human and malware alike). The evaluation performed demonstrates the capabilities of current …

Electronic-Supply Chain Information Security: A Framework For Information, Alizera Bolhari

Australian Information Security Management Conference

Over the last few years, the materials and distribution management has developed into a broader strategic approach known as electronic supply chain management by means of information technology. This paper attempts to visibly describe supply chain management information security concepts which are necessary for managers to know about. So, the depth of information presented in this paper is calibrated for managers, not technical security employees or agents. Global supply chains are exposed to diverse types of risks that rise along with increasing globalization. Electronic supply chains will be more vulnerable from information security (IS) aspect among other types of supply …

"A Change Has Swept Over Our Land": American Moravians And The Civil War, Adrienne E. Robertson

Master's Theses

When they first came to North America, the Moravians—a pietistic, Germanic Christian sect—settled in isolated communities where only a few people ventured out to do missionary work for the community. They separated themselves from their non-Moravian neighbors, one missionary community serving the North from its seat in Bethlehem, Pennsylvania, and the other serving the South from Salem, North Carolina, and neither participating in civic or military life. Then, over the course of a few decades, economic and civic circumstances forced the Moravians in North America to adapt their ways to be more like those of their non-Moravian neighbors, adopting styles …
