Comparing Theory And Experiment For Analyte Transport In The First Vacuum Stage Of The Inductively Coupled Plasma Mass Spectrometer, Matthew R. Zachreson

Theses and Dissertations

The Direct Simulation Monte Carlo algorithm as coded in FENIX is used to model the transport of trace ions in the first vacuum stage of the inductively coupled plasma mass spectrometer. Haibin Ma of the Farnsworth group at Brigham Young University measured two radial trace density profiles: one 0.7 mm upstream of the sampling cone and the other 10 mm downstream. We compare simulation results from FENIX with the experimental results. We find that gas dynamic convection and diffusion are unable to account for the experimentally-measured profile changes from upstream to downstream. Including discharge quenching and ambipolar electric fields, however, …

Treatment Of A Ring With Periodic Atomic Placement Through Differential Geometry, Gregory Karjala, Lok Lew Yan Voon

Explorations – The Journal of Undergraduate Research, Scholarship and Creativity at Wright State

Most treatments of Bloch’s Theorem have relied on group theory or other mathematical methods for its proof. In this paper we give a derivation of the quantum number first proposed by Y.C Lee and Wei Z. Lee for the Benzene ring through the use of differential geometry. We also develop a Bloch style relationship relation for the benzene ring with an additional quantum number. Through this treatment we show the usefulness of differential geometry in the theorist’s toolkit when it comes to solid-state problems.

Multivariate Data Analysis, Diana Copeland, Michael Raymer

Explorations – The Journal of Undergraduate Research, Scholarship and Creativity at Wright State

The study of biology, computer science, and information technology all combine to form the science of bioinformatics [1]. This field was created to make discoveries on new biological insights [1]. Bioinformatics has several important task one of them being able to analyze and interpret different types of data and this includes multivariate data analysis. Multivariate data analysis can use linear projection methods such as linear discriminant analysis (LDA), principal component analysis (PCA), and projection to latent structures (PLS). I have created a Java program that can manipulate multivariate data by manual rotation and will be comparing my results to the …

Using Pairs Of Criteria To Obtain Superior Stock Portfolio Performance, Abdullah Aai Yousuf

Explorations – The Journal of Undergraduate Research, Scholarship and Creativity at Wright State

This paper discusses the use of pair of financial criteria to obtain the superior stock portfolio performance. Several Portfolios are created with different number of securities over different time horizons, using pair of financial criteria and Price momentum strategy. Our results give support for the use of pairs of criteria in selecting and managing equity portfolio. The synergy effect of combining a financial ratio with the price momentum obtains both statistical and economical superior performance results; especially the pair of Earnings to Price ratio along with Price Momentum strategy with smaller of number of securities in short run.

Unresolved Question Of The 10he Ground State Resonance, Z. Kohley, J. Snyder, T. Baumann, G. Christian, P.A. Deyoung, J.E. Finck, R.A. Haring-Kaye, M. Jones, E. Lunderberg, B. Luther, S. Mosby, A. Simon, J.K. Smith, A. Spyrou, Sharon L. Stephenson, M. Thoennessen

Physics and Astronomy Faculty Publications

The group state of ¹⁰He was populated using a 2p2n-removal from a 59 MeV/u ¹⁴Be beam. The decay energy of the three body system, 8He + n + n, was measured and a resonance was observed at E = 1.60(25) MeV with a 1.8(4) MeV width. This result is in agreement with previous invariant mass spectroscopy measurements, using the ¹¹Li(-p) reaction, but is consistent with recent transfer reaction results. The proposed explanation that the difference, about 500 keV, is due to the effect of the extended halo nature of ¹¹Li in the one-proton knockout reaction is …

Ultracold Neutron Depolarization In Magnetic Bottles, A. Steyerl, Charles Kaufman, Gerhard Müller, S. S. Malik, A. M. Desai

Physics Faculty Publications

We analyze the depolarization of ultracold neutrons confined in a magnetic field configuration similar to those used in existing or proposed magnetogravitational storage experiments aiming at a precise measurement of the neutron lifetime.We use an extension of the semiclassical Majorana approach as well as an approximate quantum mechanical analysis, both pioneered by Walstrom et al. [Nucl. Instrum. Methods Phys. Res. A 599, 82 (2009)]. In contrast with this previous work we do not restrict the analysis to purely vertical modes of neutron motion. The lateral motion is shown to cause the predominant depolarization loss in a magnetic storage trap. …

Modeling Radial Bernstein Modes In A Finite-Length Axisymmetric Non-Neutral Plasma, Mark Andrew Hutchison

Theses and Dissertations

Axisymmetric radial Bernstein modes are known to exist in non-neutral plasmas and have been studied theoretically and computationally in 1D, but detection of these modes has still proven to be difficult due to self-shielding. To help advance the work on this front we created a 2D particle-in-cell (PIC) code that simulates a non-neutral plasma in a Malmberg-Penning trap. A detailed description of the PIC code itself has been included that highlights the benefits of using an $r^2$--$z$ grid and how it can be tested. The focus of the PIC simulation was to discover how best to drive and detect these …

Monitoring Land-Cover Change In The Las Vegas Valley: A Study Of Five Change Detection Methods In An Urban Environment, Bonnie Diane Weidemann

Theses and Dissertations

Change detection is currently a topic of great interest to theoretic geographic researchers. The necessity to map, monitor, and model land cover change is also important to a variety of applied fields as varied as urban planning and military intelligence. This research compares five algorithms to map urban land cover change in the greater Las Vegas, Nevada metropolitan area. Landsat Thematic Mapper imagery acquired on May 1990 and May 2000 was used as the primary data. The change detection methods yielded simple maps of change vs. no change. These algorithms included image differencing, image ratioing, image regression, vegetation index differencing, …

A Survey Of Invasive Exotic Ants Found On Hawaiian Islands: Spatial Distributions And Patterns Of Association, Camie Frandsen Martin

Theses and Dissertations

An intensive sampling of all ant species encountered on 6 Hawaiian Islands: Big Island, Maui, Oahu, Kauai, Molokai, and Lanai took place between 1988 and 1996. Species presence and absence was recorded at each site. Using remote sensing, variables were added insitu and used throughout my analysis. Species accumulation curves suggest that sampling was comprehensive. There is a significant trend between island area and species richness which validates the Theory of Island Biogeography for invasive species. Islands were found to be significantly nested by area, order, and tourism. Cluster analysis shows a link between elevation, land-use and island, and species …

Advanced Numerical Methods In General Relativistic Magnetohydrodynamics, Michael J. Besselman

Theses and Dissertations

We show our work to refine the process of evolutions in general relativistic magnetohydrodynamics. We investigate several areas in order to improve the overall accuracy of our results. We test several versions of conversion methodologies between different sets of variables. We compare both single equation and two equations solvers to do the conversion. We find no significant improvement for multiple equation conversion solvers when compared to single equation solvers. We also investigate the construction of initial data and the conversion of coordinate systems between initial data code and evolution code. In addition to the conversion work, we have improved some …

Website Adaptive Navigation Effects On User Experiences, James C. Speirs

Theses and Dissertations

The information search process within a website can often be frustrating and confusing for website visitors. Navigational structures are often complex and multitiered, hiding links with several layers of navigation that user's might be interested in. Poor navigation causes user frustration. Adaptive navigation can be used to improve the user's navigational experience by flattening the navigational structure and reducing the number of accessible links to only those that the user would be interested in. This examines the effects on a user's navigational experience, of using adaptive navigation as the main navigational structure on a website. This study measured these effects …

Investigation Of Possible Novel Peptide Inhibitors To Bag-1 Based On Peptidyl-Biomimetics, Jonathan Brunn

Theses and Dissertations

In this Master’s Thesis Research the results can be summarized from two major tasks: (1) In our first task, we utilized our two protein system (BAG-1 and HSP 70) as part of beta testing of a computational software 1 that can take three dimensional x-ray crystallography information about protein complexes and predict the strength of atom –atom interactions between amino-acid residues Open Contact predicts binding hotspots that can be used to identify short amino acid chains or peptides that mimic that particular binding segment of the larger protein. These peptides are called pepidyl-biomimetics. The peptide can potentially act as an …

Vibrotactile Feedback Generation Using Envelope Waveforms And Eccentric-Mass Motors, Michael G. Plooster

Theses and Dissertations

The usefulness of vibrotactile feedback as a channel to communicate information has been widely recognized. However, most of the recent work on this subject uses actuators that are either too expensive or too large for many practical applications. This thesis explores the generation of vibrotacatile feedback patterns using a simple, inexpensive eccentric-mass motor that is constrained to use a constant voltage and a low on/off switching frequency. In particular, it explores the pulse timing method, which utilizes the slow transient response of the eccentric-mass motor to calculate pulse and rest times for an arbitrary envelope waveform shape. Several hardware tests …

Water Use In Las Vegas, Gram Bazylinski

Anthropology 100: Feast and Famine In a Global World Poster Assignment

How Much Water Does Las Vegas Use?

Water Use Per Capita

The average household in Southern Nevada uses about 222 gallons of water per day. This has recently dropped from using 314 gallons of water per day. The southern Nevada Water Authority hopes that by the year 2035, water use will have dropped down to 199 gallons per day for each household.

The majority of Southern Nevada’s water goes to residential use, both indoor and outdoor. Because of this, restrictions have been placed on certain aspects of water use such as the amount of lawn a household can own. Aside …

Water Consumption In Southern Nevada, Paul Conyers

Anthropology 100: Feast and Famine In a Global World Poster Assignment

With its massive hotels, casinos, restaurants, and dramatic architecture it can be easy to forget that Las Vegas resides in the middle of a desert receiving just 4.5 inches of rain per year. Its population has grown immensely to nearly 2 million as of 2012 and that is without including the more than 30 million tourists visiting every year. With this growth more and more water is needed to keep yards and golf courses green, to keep the fountains of Bellagio flowing, to support the habitats of Mandalay Bay and the Flamingo, and to allow Las Vegas to maintain its …
