Turning An Organic Semiconductor Into A Low-Resistance Material By Ion Implantation, Beatrice Fraboni, Alessandra Scidà, Piero Cosseddu, Yongqiang Wang, Michael Nastasi, Silvia Milita, Annalisa Bonfiglio

Nebraska Center for Energy Sciences Research: Publications

We report on the effects of low energy ion implantation on thin films of pentacene, carried out to investigate the efficacy of this process in the fabrication of organic electronic devices. Two different ions, Ne and N, have been implanted and compared, to assess the effects of different reactivity within the hydrocarbon matrix. Strong modification of the electrical conductivity, stable in time, is observed following ion implantation. This effect is significantly larger for N implants (up to six orders of magnitude), which are shown to introduce stable charged species within the hydrocarbon matrix, not only damage as is the case …

Computation Of A Virtual Tide Corrector To Support Vertical Adjustment Of Autonomous Underwater Vehicle Multibeam Sonar Data, Lawrence H. Haselmaier

LSU New Orleans Theses and Dissertations

One challenge for Autonomous Underwater Vehicle (AUV) multibeam surveying is the limited ability to assess internal vertical agreement rapidly and reliably. Applying an external ellipsoid reference to AUV multibeam data would allow for field comparisons. A method is established to merge ellipsoid height (EH) data collected by a surface vessel in close proximity to the AUV. The method is demonstrated over multiple collection missions in two separate areas. Virtual tide corrector values are derived using EH data collected by a boat and a measured ellipsoid to chart datum separation distance. Those values are compared to measurements by a traditional tide …

Correlations Between Quantitative Fat–Water Magnetic Resonance Imaging And Computed Tomography In Human Subcutaneous White Adipose Tissue, Aliya Gifford, Ronald C. Walker, Theodore F. Towse, E Brian Welch

Peer Reviewed Articles

Beyond estimation of depot volumes, quantitative analysis of adipose tissue properties could improve understanding of how adipose tissue correlates with metabolic risk factors. We investigated whether the fat signal fraction (FSF) derived from quantitative fat–water magnetic resonance imaging (MRI) scans at 3.0 T correlates to CT Hounsfield units (HU) of the same tissue. These measures were acquired in the subcutaneous white adipose tissue (WAT) at the umbilical level of 21 healthy adult subjects. A moderate correlation exists between MRI- and CT-derived WAT values for all subjects, R²=0.54, p<0.0001, with a slope of −2.6, (95% CI [−3.3,−1.8]), indicating that a decrease of 1 HU equals a mean increase of 0.38% FSF. We demonstrate that FSF estimates obtained using quantitative fat–water MRI techniques correlate with CT HU values in subcutaneous WAT, and therefore, MRI-based FSF could be used as an alternative to CT HU for assessing metabolic risk factors.

An Examination Of Voter Groups That Make Up The Emerging Democratic Majority Thesis, Jason Waguespack

LSU New Orleans Theses and Dissertations

In 2002, John Judis and Ruy Teixeira published The Emerging Democratic Majority, a book that postulated that the United States was in the beginning of a political realignment that would spell the end of the Reagan-era coalition that gave Republicans an electoral advantage on the presidency. The authors claimed an electorate that would favor the Democratic Party would emerge to take its place. Since Senator Barack Obama’s victory in the 2008 presidential election was powered by a coalition that looked much like the one Judis and Teixeira described, it appeared the authors’ thesis was being borne out by actual …

Characterizing Far-Infrared Laser Emissions And The Measurement Of Their Frequencies, Michael Jackson, Lyndon R. Zink

All Faculty Scholarship for the College of the Sciences

The generation and subsequent measurement of far-infrared radiation has found numerous applications in high-resolution spectroscopy, radioastronomy, and Terahertz imaging. For about 45 years, the generation of coherent, far-infrared radiation has been accomplished using the optically pumped molecular laser. Once far-infrared laser radiation is detected, the frequencies of these laser emissions are measured using a three-laser heterodyne technique. With this technique, the unknown frequency from the optically pumped molecular laser is mixed with the difference frequency between two stabilized, infrared reference frequencies. These reference frequencies are generated by independent carbon dioxide lasers, each stabilized using the fluorescence signal from an external, …

From Containing Communism To Fighting Floods: The Louisiana Army National Guard In The Cold War, 1946-1965, Rhett G. Breerwood

LSU New Orleans Theses and Dissertations

In the decades following World War II, the Louisiana National Guard evolved due to world, national, and local events. In response to the United States’ Cold War policies to contain Communism, the Guard expanded, professionalized, and was occasionally called to federal service. In conjunction with Cold War fears of external attack and internal subversion, a civil defense mission brought coordination between federal, state and local response agencies. Despite the lack of large scale war service or an attack on the U.S. homeland , the skills and responsibilities acquired by the Louisiana Guard during this time period resulted in an enhanced …

Second Lieutenant Charles Scheffel, B Company Platoon Leader, 39^th Infantry Regiment, 9^th Infantry Division modified existing methods of venereal disease control in Algeria, North Africa during Operation Torch after being ordered to reduce the venereal disease rate by his regimental commander, Colonel William Ritter. Tasked with defeating the Germans first, Scheffel learned other enemies lurked as well, and he instituted an illegal policy to solve the problem as fast and as effectively as possible. Official United States policy on the eve of World War Two prohibited the establishment and operation of a brothel. Scheffel operated this brothel as …

Three Dimensional Nanowire Array Piezo-Phototronic And Piezo-Photo-Magnetotronic Sensors, Satish C. Rai

LSU New Orleans Theses and Dissertations

Piezotronic and piezo-phototronic is a burgeoning field of study which emerges from the coupling of intrinsic materials properties exhibited by non-centrosymmetric semiconductors. In the past decade research efforts were mainly focused on the wurtzite family of 1D nanostructures, with major emphasis on ZnO nanowire nanogenerators, MS piezotronic transistors, LEDs and photodetectors mainly integrated on single nanowires. In view of previously known advantages of charge carrier separation in radial heterojunctions, particularly in type-II core/shell nanowires, it can be anticipated that the performance of photosensing devices can be largely enhanced by piezo-phototronic effect. Moreover, the performance metrics can be further improved in …

Developing And Testing An Anguilliform Robot Swimming With Theoretically High Hydrodynamic Efficiency, John B. Potts Iii

LSU New Orleans Theses and Dissertations

An anguilliform swimming robot replicating an idealized motion is a complex marine vehicle necessitating both a theoretical and experimental analysis to completely understand its propulsion characteristics. The ideal anguilliform motion within is theorized to produce ``wakeless'' swimming (Vorus, 2011), a reactive swimming technique that produces thrust by accelerations of the added mass in the vicinity of the body. The net circulation for the unsteady motion is theorized to be eliminated.

The robot was designed to replicate the desired, theoretical motion by applying control theory methods. Independent joint control was used due to hardware limitations. The fluid velocity vectors in the …

Response Of Fishes To Restoration Projects In Bayou St. John Located Within The City Of New Orleans, Louisiana, Including Hydrological Characterization And Hydrodynamic Modelling, Patrick W. Smith

LSU New Orleans Theses and Dissertations

Quantifying the impacts of restoration on coastal waterways is crucial to understanding their effectiveness. Here, I look at the impacts of multiple restoration projects on urban waterways within the city limits of New Orleans, LA, with an emphasis on the response of fishes. First I report the effects of two projects designed to improve exchange down estuary on the hydrologic characteristics of Bayou St. John (BSJ). Within BSJ, flow is dominated by subtidal wind driven processes. Removal of an outdated flood control structure did not appear to alter exchange in BSJ, but removal combined with sector gate openings did. I …

In the beginning, this numeric model is implemented in MATLAB/Simulink® and it is used to predict the performance of a three phase squirrel single-cage type induction motor/generator in two different cases. The first case is a small 3 meter rotor diameter, 20 kW ocean current turbine with fixed pitch blades, and the second case a 20 …

Modeling And Analysis Of A Steel Truss Railroad Bridge Traversed By Trains At Various Speeds, Surendra Baniya Mr.

Master's Theses

The dynamic analysis of a truss railroad bridge under a moving train is very complicated. The simplified model where an entire bridge is represented by a single beam of equivalent stiffness could be suitable to analyze a girder bridge, but is not adequate to analyze accurately truss bridges, which inherently consist of numerous structural components. Moreover, due to the repetitive nature of train loading on a railroad bridge, there is an excitation frequency as a function of speed associated with each moving train. If this loading (excitation) frequency coincides with the natural frequency of the bridge, the bridge response builds …

Pulsed Photonic Curing Of Conformal Printed Electronics, Sourav Das

Theses

As next-generation electronic products emerge, there is a need to create more electronic functionality in compact spaces. One of the techniques to achieve this is by integrating electronic circuitry on mechanical stress bearing parts of electro-mechanical products. Direct-write printing processes like inkjet printing and aerosol jet printing can be used to print conductive inks on conformal surfaces of mechanical components. Advanced curing/sintering processes such as pulsed photonic curing can be used to cure/sinter printed inks to produce conductive traces. However, the use of photonic curing on conformal surfaces introduces two sources of variability into the process, which are the distance …

Alarm Management: Electrocardiographic Lead Management, Dale Elaine Dominguez Ms.

Master's Projects and Capstones

Abstract

Alarm Management: Electrocardiographic Lead Management

Quality improvement and safety that incorporates the Clinical Nurse Leader (CNL) competency of putting in place quality improvements plans that are bases on evidence, analysis, and risk anticipation is the thesis for this project. The associated problem is the myriads of electrocardiographic (ECG) alarms that alert staff to patient issues each day. Of those alerts, 88% to 90% are false or do not require immediate attention (Sendelbach & Jepsen, 2013). The high numbers of false alerts cause staff to become desensitized to the sound. This desensitization may cause staff not to respond to a …

Urban Stormwater Management: Treatment Of Heavy Metals And Polycyclic Aromatic Hydrocarbons With Bioretention And Permeable Pavement Technologies, Viktoriya Sirova

Master's Projects and Capstones

Urban stormwater runoff is a major non-point source of pollutants release into the environment. Pollutants of concern include sediments; heavy metals; polycyclic aromatic hydrocarbons (PAHs); petroleum hydrocarbons; and chlorinated organic compounds, such as pesticides and polychlorinated biphenyls. Conventional stormwater management practices are designed to dispose of the runoff as quickly as possible, not to treat the pollutants. Low Impact Development (LID) concept is an alternative approach to the conventional framework that attempts to recreate hydrologically functional landscape mimicking pre-development regimes. This research paper assesses the effectiveness of two LID technologies, bioretention and permeable pavements in treating PAHs and common urban …

Adapting To Rising Sea Levels In San Francisco Bay: The Potential For Thin Layer Sediment Application To Enhance Tidal Marsh Resiliency Through This Century, Scott K. Hine

Master's Projects and Capstones

The research here focuses on two projected century sea-level rise scenarios (100 and 180 cm/century) and the potential to offset elevation loss to sea-level rise by supplying deteriorating tidal marsh habitat with a thin layer of dredge sediment via high-pressure spray disposal within San Francisco Bay. This adaptation strategy is then analyzed for potential integration into the Bay’s long term management plan for dredge material disposal. The Marsh Equilibrium Model (Morris, 2012) is used to evaluate elevation deficits for existing tidal marsh habitat around San Pablo Bay against future century sea-level rise scenarios and model marsh resiliency following elevation enhancement. …
