Design and Analysis of Distributed Resource Allocation Techniques for Large-Scale Dynamic Spectrum Access Networks

Creator:: NoroozOliaee, MohammadJavad
Abstract:: The widespread use of wireless devices that we have recently been witnessing, such as smartphones, tablets, laptops, and wirelessly accessible devices in general, is causing an unprecedented growth in the required amount of the wireless radio spectrum. On the other hand, the spectrum resource has, for the last several decades,...

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...

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...

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...

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...

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...

Application and Validation of Geant4 Modeling for Optimization of Complex Structures for Fast Neutron Detection

Creator:: Capps, Jacob W.
Abstract:: Fast neutron detection is important to the detection of illicit nuclear materials and can help prevent those materials from being used or transported without discovery. Previous research has shown that Heavy Oxide Inorganic Scintillator crystals can be used to detect fast neutrons by capitalizing on their high inelastic scattering cross...

Cherenkov Glass Detectors for Gamma and Neutron Detection

Creator:: Natto, Hattan
Abstract:: Cherenkov detectors have been developed and used in several fields since the discovery of Cherenkov radiation. They do have several advantages compared with other detector types, such as low noise due to the low-energy threshold of Cherenkov radiation, and short decay constant (on the order of picoseconds). However, the light...

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...
