Design and evaluation of test bed software for a smart antenna system supporting wireless communication in rural areas: Author: Panique, Michael David; Date: 2008-05-15; Program: Electrical Engineering; Abstract: This paper explores the design and development of a test bed to analyze feasibility of utilizing adaptive smart antennas in conjunction with high bandwidth WiMAX radio systems to achieve improved performance for mobile nodes and to suppress potential interference from unwanted signals. Although the new WiMAX standard offers the potential for using smart, adaptive antennas, this functionality has not been implemented. This design serves as a common platform for testing adaptive array algorithms including direction of arrival (DOA) estimation, beamforming, and adaptive tracking, as well as compl...; Download File | View full details

System for Wireless, Automated and Continuous Monitoring of Resonant Frequency of an Inductor - Capacitor Circuit: Author: Sajeeda; Date: 2004-05-15; Program: Electrical Engineering; Abstract: This thesis presents a new technique for remote query monitoring of environmental parameters such as pressure, temperature, humidity, complex permittivity, temperature, strain and gases like carbon dioxide, oxygen and ammonia. Resonant peak passive telemetry is used for wireless remote monitoring. The resonance frequency of an inductor-capacitor (LC) circuit sensor changes with the surrounding environmental parameter and detector circuitry employing a loop antenna is used to remotely identify the resonance frequency. The mutual coupling between the antenna and the sensor inductor enables wirel...; Download File | View full details

Data Analysis for Space-Based Gravitational Wave Detectors: Author: Crowder, Jefferson Osborn; Date: 2006-05-15; Program: Physics; Abstract: With the launch of the Laser Interferometer Space antenna (LISA) expected for the next decade, the nascent field of gravitational wave astronomy will be taking a giant leap forward. The data that will be gathered from space-borne gravitational wave detectors such as LISA will provide an expansive look through a new window on the Universe. This dissertation is presented to help open that window by exploring some of the techniques and methods that will be needed to understand the data from these detectors. The first original work presented here investigates the resolution of LISA and follow-on s...; Download File | View full details

Gravitational Wave Astronomy using Spaceborne Detectors: Author: Rubbo, Louis Joseph; Date: 2004-08-15; Program: Physics; Abstract: This dissertation explores the use of spaceborne gravitational wave detectors as observatories for studying sources of gravitational radiation. The next decade will see the launch of the first space-based gravitational wave detector. Planning for several follow on missions is already underway. Before these observatories are constructed, extensive studies into their responses, expected output, and data analysis techniques must be completed. In this dissertation these issues are addressed using the proposed Laser Interferometer Space antenna as an exemplary model. The first original work present...; Download File | View full details

Assessment of Culvert Passage of Yellowstone Cutthroat Trout in a Yellowstone River Spawning Tributary Using A Passive Integrated Transponder System: Author: Solcz, Andrew Anthony; Date: 2007-08-15; Program: Fish and Wildlife Management; Abstract: Road crossing culverts can pose passage barriers during salmonid migration. However, existing models to predict passage have not been sufficiently tested, particularly for non-anadromous species. In addition, most existing tools for evaluating culvert passage status categorize culverts as passable or impassable whereas an estimate of the probability of passage under a range of flows and hydraulic conditions would be more useful for assessing barrier status. This study used Half-duplex (HDX) Passive Integrated Transponder (PIT) tags and PIT tag reading antennas to examine the ability of migrati...; Download File | View full details

Determining the biomechanical response of a filiform hair array: a low Reynolds number fluid-structure model: Author: Cummins, Breschine; Date: 2009-08-15; Program: Mathematics; Abstract: A model system that has been the subject of many anatomical, developmental, functional, and theoretical studies over the last 30 years is the cercal sensory system of the cricket. This system is composed of two antenna-like appendages covered with hundreds of filiform mechanosensory hairs, and encodes information about the direction and dynamics of low-velocity air currents. The encoding is determined by the biomechanical properties of the mechanosensory hairs. These properties are poorly understood, primarily because accurate experimental measurements of the air-current-driven movements of th...; Download File | View full details
