Development And Optimization Of A Reconfigurable Telemetry System For Sounding Rocket Payloads, Niladri Si Dec 2007

Development And Optimization Of A Reconfigurable Telemetry System For Sounding Rocket Payloads, Niladri Si

Engineering

This thesis addresses the development of a flight-ready telemetry encoder for the Alaska Student Rocket Project (ASRP) sounding rocket payload. The Frame Oriented eXpandable Integrated circuit Encoder-2007 (FOXIE-07) was developed to resolve crosstalk, timing, and thermal issues in the original FOXIE-03 encoder prototype. A pre-modulation low-pass filter was implemented between the encoder and the FM transmitter to minimize undesired sidebands from the transmitted signal. Complete testing of the FOXIE-07 encoder and pre-modulation filter was performed to certify them as flight-ready components for the SRP5 payload launch from Poker Flat Research Range in 2009.

Analysis Of A Chemically-Bonded Phosphate Ceramic As An Alternative Oilfield Cementing System For Arctic Regions, Nilesh Limaye

Engineering

Novel chemically bonded phosphate ceramic borehole sealant, i.e. Ceramicrete, has many advantages over conventionally used permafrost cement at Alaska North Slope (ANS). However, in normal field practices when Ceramicrete is mixed with water in blenders, it has a chance of being contaminated with leftover Portland cement. In order to identify the effect of Portland cement contamination, recent tests have been conducted at BJ services in Tomball, TX as well as at the University of Alaska Fairbanks with Ceramicrete formulations proposed by the Argonne National Laboratory. The tests conducted at BJ Services with proposed Ceramicrete formulations and Portland cement contamination have …


A Unified Framework For Solving Multiagent Task Assignment Problems, Kevin Cousin Dec 2007

A Unified Framework For Solving Multiagent Task Assignment Problems, Kevin Cousin

Theses and Dissertations

Multiagent task assignment problem descriptors do not fully represent the complex interactions in a multiagent domain, and algorithmic solutions vary widely depending on how the domain is represented. This issue is compounded as related research fields contain descriptors that similarly describe multiagent task assignment problems, including complex domain interactions, but generally do not provide the mechanisms needed to solve the multiagent aspect of task assignment. This research presents a unified approach to representing and solving the multiagent task assignment problem for complex problem domains. Ideas central to multiagent task allocation, project scheduling, constraint satisfaction, and coalition formation are combined to …

Reconfiguration Of Shipboard Power Systems Using A Genetic Algorithm, Koteshwar Reddy Padamati

Theses and Dissertations

The shipboard power system supplies energy to sophisticated systems for weapons, communications, navigation, and operation. After a fault is encountered, reconfiguration of a shipboard power system becomes a critical activity that is required to either restore service to a lost load or to meet some operational requirements of the ship. Reconfiguration refers to changing the topology of the power system in order to isolate system damage and/or optimize certain characteristics of the system related to power efficiency. When finding the optimal state, it is important to have a method that finds the desired state within a short amount of time, …


Video Coding With 3d Wavelet Transforms, Joseph Bradley Boettcher Dec 2007

Video Coding With 3d Wavelet Transforms, Joseph Bradley Boettcher

Theses and Dissertations

Video coding systems based on 3D wavelet transforms offer several advantages over traditional hybrid video coders. This thesis proposes two 3D wavelet-based video-coding approaches. In the first approach, motion compensation with redundant-wavelet multihypothesis, in which multiple predictions that are diverse in transform phase contribute to a single motion estimate, is deployed into the fully scalable MC-EZBC video coder. The bidirectional motion-compensated temporaliltering process of MC-EZBC is adapted to the redundant-wavelet domain, wherein transform redundancy is exploited to generate a phase-diverse multihypothesis prediction of the true temporal filtering. In the second approach, a video coder is proposed that does not perform …


Intelligent Placement Of Meters/Sensors For Shipboard Power System Analysis, Sandhya Sankar Dec 2007

Intelligent Placement Of Meters/Sensors For Shipboard Power System Analysis, Sandhya Sankar

Theses and Dissertations

Real time monitoring of the shipboard power system is a complex task to address. Unlike the terrestrial power system, the shipboard power system is a comparatively smaller system but with more complexity in terms of its system operation. This requires the power system to be continuously monitored to detect any type of fluctuations or disturbances. Planning metering systems in the power system of a ship is a challenging task not only due to the dimensionality of the problem, but also due to the need for reducing redundancy while improving network observability and efficient data collection for a reliable state estimation …

Increasing The Efficiency Of Network Interface Card, Amit Uppal Dec 2007

Increasing The Efficiency Of Network Interface Card, Amit Uppal

Theses and Dissertations

A Network Interface Card (NIC) is used for receiving the packets, processing the packets, passing the packets to the host processor, and sending the packets to other computers in a network. NIC uses the buffer management algorithm to distribute the buffer space among different applications. An application may use User Datagram Protocol (UDP) or Transmission Control Protocol (TCP), depending upon the type of application. Buffer Management Algorithm for UDP-based applications may be completely different from the one for TCP applications, since in UDP- based applications receiver do not send acknowledgement back to the sender. This thesis proposes two buffer management …


Dynamic Electron-Phonon Interactions In One Dimensional Models, Rahul Padmakar Hardikar Dec 2007

Dynamic Electron-Phonon Interactions In One Dimensional Models, Rahul Padmakar Hardikar

Theses and Dissertations

We study the unusual phases seen in charge transfer salts (CTS) at 1/2 and 1/4 filling. We use the Holstein-Hubbard model (HHM) and the Peierls extended Hubbard model (PEH) to study competing phases in CTS. In the 1/2illed HHM the Holstein coupling promotes a Peierls charge-density wave phase while the on-site Coulomb repulsion U gives rise to antiferromagnetic correlations and a Mott insulating state. Takada et al. have shown possibility of a third metallic phase between the Mott and the Peierls phase. We investigate the presence of an intermediate phase between the Mott and Peierls phase using Stochastic Series Expansion …


Full Scale Instrumented Testing And Analysis Of Matting Systems For Airfield Parking Ramps And Taxiways, Chad A. Gartrell Dec 2007

Full Scale Instrumented Testing And Analysis Of Matting Systems For Airfield Parking Ramps And Taxiways, Chad A. Gartrell

Theses and Dissertations

The U.S. military requires the ability to rapidly deploy troops, equipment, and materials anywhere in the world. Recent operations have brought attention to the need to utilize austere, unsurfaced, and sometimes sub-standard airfields within a theater of interest. These airfields may require additional taxiways and aprons. One option for the rapid construction of such is airfield matting systems. The focus of the work for this thesis was commercially available airfield matting systems to support large military transport aircraft, such as the C 17. Several test sections with differing strength soils were built with chosen mats tested in an elimination method, …


Development Of Bio-Photonic Sensor Based On Laser-Induced Fluorescence, Chan Kyu Kim Dec 2007

Development Of Bio-Photonic Sensor Based On Laser-Induced Fluorescence, Chan Kyu Kim

Theses and Dissertations

Laser-induced fluorescence (LIF) has been shown to be potentially useful for identifying microorganisms in real time. It is a selective and sensitive technique because the excitation is performed at one wavelength while the emission is monitored at longer wavelengths so that background from the excitation source can be eliminated. This specialized optical property of LIF can be applied to development of an optical sensor capable of quickly, non-invasively, and quantitatively probing complex biochemical transformations in microorganisms. Various bio-photonic optical fiber sensors based on laser-induced fluorescence (LIF) spectroscopy were developed as diagnostic tools for microorganisms. In the first phase, the enhancement …


On The Determination Of Building Footprints From Lidar Data, Henry C. George Dec 2007

On The Determination Of Building Footprints From Lidar Data, Henry C. George

LSU New Orleans Theses and Dissertations

A new approach to improve the determination of building boundaries through automatic processing of light detection and ranging (LIDAR) data is presented. The LIDAR data is processed and interpolated into a grayscale image of intensity values corresponding to height measurements. Ground measurements are separated from non-ground measurements by using a progressive morphological filter. With these measurements now distinct, further separation of non-ground measurements into building and non-building measurements is performed by growing regions with similar characteristics. These building areas are then refined, resulting in a ground plan representation of building boundaries, known as building footprints. Several algorithms are then implemented …


Long-Term Ambient Noise Statistics In The Gulf Of Mexico, Mark Alan Snyder Dec 2007

Long-Term Ambient Noise Statistics In The Gulf Of Mexico, Mark Alan Snyder

The buoys were located near a major shipping lane, with an estimated 1.5 to 4.5 ships per day passing nearby. The data were sampled at 2500 Hz and have a bandwidth of 10-1000 Hz. Data are …


Feasibility Of The Use Of Two Spent Blast Materials As Aggregate In Hot Mix Asphalt In Louisiana Post-Katrina, Amer Kholoqui Khanfar Dec 2007

Feasibility Of The Use Of Two Spent Blast Materials As Aggregate In Hot Mix Asphalt In Louisiana Post-Katrina, Amer Kholoqui Khanfar

LSU New Orleans Theses and Dissertations

Using spent abrasive blast material (ABM) in hot mix asphalt to replace part of the fine aggregates used in the production of conventional hot mix asphalt has several environmental benefits. First, onsite storage of spent ABMs negatively impact neighboring properties because the fine materials are a source of airborne debris and dust. Use of tarps as curtains only reduces this hazard. Secondly, storage piles of this waste are situated near canals, waterways and the Mississippi River. Future storms may carry these waste products into the neighboring waterways. Most importantly, these wastes are ultimately disposed of in non-hazardous landfills. Reuse of …
