Small Scale Modeling of a Broad Area Detector Network Array

Creator:: Johnson, Patrick M.
Abstract:: Nuclear material monitoring systems have long been established at ports of entry. However, there are no standard systems for monitoring points of interest within the country. Therefore, the use of a network of radiation sensors deployed throughout an area of interest is being investigated within this thesis. Before full scale...

Use of CR-39 for nuclear criticality accident dosimetry and high neutron dose monitoring

Creator:: Tai, Lydia I.
Abstract:: CR-39 foils were irradiated as part of nuclear accident dosimetry experiments using the Godiva reactor at the Nevada National Security Site and the Caliban and Prospero reactors at the Valduc Centre for Nuclear Studies in France. The irradiated foils were chemically etched using the standard Lawrence Livermore National Laboratory process...

A quantitative comparison of cardiovascular imaging systems with respect to the resolution capabilities and the resulting skin entrance doses operating in both fluoroscopic and cine mode

Creator:: Helms, W. Scott
Abstract:: The increasing use of medical procedures using ionizing radiation has increased significantly in recent years. In 1987, the National Council on Radiation Protection Report 93 (NCRP) reported that the average exposure ionizing radiation was 53mRem/year (0.53mSv/year). In their most recent study on radiation exposures NCRP Report 160 in 2009, the...

Comparison of object detection and image quality between conventional digital mammography and digital breast tomosynthesis through contrast measurements and phantom image evaluation

Creator:: Leek, Angela E.
Abstract:: Advancements in digital detector technology over the past decade have facilitated the transition of mammography image acquisition from film screen to full field digital applications. Nearly 90% of the mammography performed in the United States utilizes digital imaging technologies. The ability to capture the image information in an electronic format...

Progress in the development of a portable phoswich-style skin contamination dosimeter

Creator:: Tang, Matthew M.
Abstract:: The Code of Federal Regulations (10CFR20.1201) mandates occupational dose limits to the shallow, lens and deep tissue layers. The NRC-accepted procedure of estimating dose to these layers from contamination events is laborious. The current work aims to further the development of a portable phoswich-style skin dosimeter that will operate in...

Coordinating secondary-user behaviors for inelastic traffic reward maximization in large-scale DSA networks

Creator:: NoroozOliaee, MohammadJavad
Abstract:: We develop efficient coordination techniques that support inelastic traffic in large-scale distributed dynamic spectrum access DSA networks. By means of any learning algorithm, the proposed techniques enable DSA users to locate and exploit spectrum opportunities effectively, thereby increasing their achieved throughput (or "rewards" to be more general). Basically, learning algorithms...

Dual referencing guidelines to minimize power delivery noise coupling

Creator:: Mark, Shannon
Abstract:: Dual referencing has been garnering a lot of attention in the power integrity community, specifically in the voltage mode driver application because it shows a lower overall power delivery noise (PDN) compared to other signal referencing types. Additionally, the increasing push to drive down package and board manufacturing costs is...

Characterization of a fiber optic coupled dosimeter for clinical electron beam dosimetry

Creator:: Nitzling, Kevin Dave
Abstract:: Fiber-optic-coupled dosimeters (FOCDs) are a relatively new method in which to obtain in-vivo dose concomitant with radiation treatment. Accurate live dosing can be achieved virtually anywhere due to their small dimensions (0.2 mm) which can be accommodated by a catheter. The purpose of this experiment is to characterize the electron...

Design, construction, and analysis of a skin contamination dosimeter

Creator:: Cazalas, Edward J.
Abstract:: International recommendations provided by the International Commission on Radiation Protection (ICRP), as well as national regulations, set by the U.S. Nuclear Regulatory Commission (NRC), state that the exposure of skin to highly concentrated radioactive sources should be monitored at specified depths in skin and kept below specific dose equivalence levels....
Resource Type:: Masters Thesis
Full Text:: pulse shape analysis. The doctoral work of Farsoni (2006) serves as a model for the future work

An ultra low voltage micropower GPS receiver RF front-end for wildlife tracking

Creator:: Heiberg, Adam C.
Abstract:: A fully integrated CMOS GPS receiver RF front end optimized for low power operation is presented. The system operates with a supply voltage down to 250 mV. A prototype has been fabricated in a 0.13μm CMOS process and includes a low voltage LNA, quadrature oscillators, and quadrature mixers. It exhibits...
