Viability Of Bismuth As A Green Substitute For Lead In Jacketed .357 Magnum Revolver Bullets, Joel A. Jenkins

USF Tampa Graduate Theses and Dissertations

In seeking to develop environmentally friendly lead-free non-toxic bullets, the research ballistically evaluated the performance of copper-jacketed handgun bullets containing a pure bismuth core. The lead was first removed from 140 grain Hornady^TM XTP® bullets of 38 caliber (.357 diameter) by melting. The empty jackets were then refilled with pure bismuth, including the forming of a correctly sized hollow-point cavity. Due to the lower density of bismuth as compared to lead, the bismuth-cored bullets consistently weighed 125 gains. Conveniently this allowed direct comparison to commercially available 125 grain Hornady^TM XTP® lead-cored bullets of 38 caliber. Both bismuth-cored and …

Can Passive Mobile Application Traffic Be Identified Using Machine Learning Techniques, Peter Holland

Dissertations

Mobile phone applications (apps) can generate background traffic when the end-user is not actively using the app. If this background traffic could be accurately identified, network operators could de-prioritise this traffic and free up network bandwidth for priority network traffic. The background app traffic should have IP packet features that could be utilised by a machine learning algorithm to identify app-generated (passive) traffic as opposed to user-generated (active) traffic. Previous research in the area of IP traffic classification focused on classifying high level network traffic types originating on a PC device. This research was concerned with classifying low level app …

Analysis Of A Low-Angle Annular Expander Nozzle, Kyll Schomberg, John Olsen, Graham Doig

Aerospace Engineering

An experimental and numerical analysis of a low-angle annular expander nozzle is presented to observe the variance in shock structure within the flow field. A RANS-based axisymmetric numerical model was used to evaluate flow characteristics and the model validated using experimental pressure readings and schlieren images. Results were compared with an equivalent converging-diverging nozzle to determine the capability of the wake region in varying the effective area of a low-angle design. Comparison of schlieren images confirmed that shock closure occurred in the expander nozzle, prohibiting the wake region from affecting the area ratio. The findings show that a low angle …

Techniques For Aerodynamic Analysis Of Cornering Vehicles, James Keogh, Tracie J. Barber, Sammy Diasinos, Graham Doig

Aerospace Engineering

When a vehicle travels through a corner it can experience a significant change in aerodynamic performance due to the curved path of its motion. The yaw angle of the flow will vary along its length and the relative velocity of the flow will increase with distance from the central axis of its rotation. Aerodynamic analysis of vehicles in the cornering condition is an important design parameter, particularly in motorsport. Most racing-cars are designed to produce downforce that will compromise straight-line speed to allow large gains to be made in the corners. Despite the cornering condition being important, aerodynamicists are restricted …

Differential Effects Of Buffer Ph On Ca2+-Induced Ros Emission With Inhibited Mitochondrial Complexes I And Iii, Daniel P. Lindsay, Amadou K. S. Camara, David F. Stowe, Mohammed Aldakkak, Ryan Lubbe

Biomedical Engineering Faculty Research and Publications

Excessive mitochondrial reactive oxygen species (ROS) emission is a critical component in the etiology of ischemic injury. Complex I and complex III of the electron transport chain are considered the primary sources of ROS emission during cardiac ischemia and reperfusion (IR) injury. Several factors modulate ischemic ROS emission, such as an increase in extra-matrix Ca²⁺, a decrease in extra-matrix pH, and a change in substrate utilization. Here we examined the combined effects of these factors on ROS emission from respiratory complexes I and III under conditions of simulated IR injury. Guinea pig heart mitochondria were suspended in experimental …

P-08 Paper-Based Biosensor For Colorimetric Detection Of Psa Biomarker, Alyson E. Drew

Honors Scholars & Undergraduate Research Poster Symposium Programs

Prostate cancer is detected by excess PSA in the bloodstream, a protein the prostate overproduces when tumors are present. In this paper, we designed an origami paper analytical device, specific to PSA using gold nanoparticles which provide a colorimetric, qualitative, inexpensive, disposable design to detect PSA. Our device separates the sample laterally to prevent back-mixing and vertically to enable addition of novel particles. The design was optimized for channel thickness, size, proper heating, type of paper involved, and amount of sample solution needed. We are currently concept-testing of PSA qualitative detection via sandwich assay to target detection levels < 100ng/mL.

Physics and Astronomy Faculty Publications

The static and dynamic magnetic responses of patterned ferromagnetic thin films are uniquely altered in the case of aperiodic patterns that retain long-range order (e.g., quasicrystals). We have fabricated permalloy wire networks based on periodic square antidot lattices (ADLs) distorted according to an aperiodic Fibonacci sequence applied to two lattice translations, d₁  = 1618 nm and d₂  = 1000 nm. The wire segment thickness is fixed at t = 25 nm, and the width W varies from 80 to 510 nm. We measured the DC magnetization between room temperature and 5 K. Room-temperature, narrow-band (9.7 GHz) ferromagnetic resonance …

Assessment Of Surface Soil Moisture Using High-Resolution Multi-Spectral Imagery And Artificial Neural Networks, Leila Hassan-Esfahani, Alfonso F. Torres-Rua, Austin M. Jensen, Mac Mckee

Civil and Environmental Engineering Faculty Publications

Many crop production management decisions can be informed using data from high-resolution aerial images that provide information about crop health as influenced by soil fertility and moisture. Surface soil moisture is a key component of soil water balance, which addresses water and energy exchanges at the surface/atmosphere interface; however, high-resolution remotely sensed data is rarely used to acquire soil moisture values. In this study, an artificial neural network (ANN) model was developed to quantify the effectiveness of using spectral images to estimate surface soil moisture. The model produces acceptable estimations of surface soil moisture (root mean square error (RMSE) = …
