An Underwater Channel Model And Chirp Slope Keying Modulation Scheme Performance, Brice Zoh Dec 2010

An Underwater Channel Model And Chirp Slope Keying Modulation Scheme Performance, Brice Zoh

LSU New Orleans Theses and Dissertations

Chirp-Slope Keying (CSK) is a new and innovative digital modulation scheme for underwater data transmission. The underwater environment brings up several challenges to the manufacturing and operation of communication systems. This thesis shows through analysis and simulations the effectiveness of Chirp-Slope Keying (CSK) in providing a satisfying performance in underwater communication. The experiment consists of modulating a chirp slope by binary numbers (representing our data). '0' is represented by a linear- down chirp and '1' is represented by a linear-up chirp. The received data is first processed by a correlator receiver. Then, the detection of either binary symbol is obtained …

In The Middle, Nicole Pugh

LSU New Orleans Theses and Dissertations

A woman just getting settled in New Orleans with her fiancé is uprooted by Hurricane Katrina. She spends the two months after the hurricane in various parts of Louisiana trying to pick up the pieces of her uprooted reality. Along the way, she encounters ordinary people who act as inspirations and is also reminded of her deceased Chinese grandmother, whom she was care-giver to before she died and whose stories about life in China and the US parallel the woman´s own life during the post-Katrina months of vulnerability and change.

Latency And Distortion Compensation In Augmented Environments Using Electromagnetic Trackers, Henry Himberg Dec 2010

Latency And Distortion Compensation In Augmented Environments Using Electromagnetic Trackers, Henry Himberg

Theses and Dissertations

Augmented reality (AR) systems are often used to superimpose virtual objects or information on a scene to improve situational awareness. Delays in the display system or inaccurate registration of objects destroy the sense of immersion a user experiences when using AR systems. AC electromagnetic trackers are ideally for these applications when combined with head orientation prediction to compensate for display system delays. Unfortunately, these trackers do not perform well in environments that contain conductive or ferrous materials due to magnetic field distortion without expensive calibration techniques. In our work we focus on both the prediction and distortion compensation aspects of …

Crisis: Capitalism, Economics And The Environment, Raj Navanit Patel Mr Dec 2010

Crisis: Capitalism, Economics And The Environment, Raj Navanit Patel Mr

Undergraduate Economic Review

The basic thesis of this paper is that there is an undeniable tension between maximization of individual welfare and a sustainable and healthy environment in a finite world. Following from this, the further claim is that our current capitalist system of private production and ownership is fundamentally in tension with the environment and should be changed. Without a change in attitude toward our conceptualization of these problems, that is, without contextualizing these problems outside of the market-based solutions and free market solutions, crisis is inevitable. Homo economicus needs to be replaced by homo environmentus.

The Effects Of Permafrost Degradation On Soil Carbon Dynamics In Alaska's Boreal Region, Jonathan A. O'Donnell Dec 2010

The Effects Of Permafrost Degradation On Soil Carbon Dynamics In Alaska's Boreal Region, Jonathan A. O'Donnell

Biological Sciences

High-latitude regions store large quantities of organic carbon (C) in permafrost soils and peatlands, accounting for nearly half of the global belowground C pool. Projected climate warming over the next century will likely drive widespread thawing of near-surface permafrost and mobilization of soil C from deep soil horizons. However, the processes controlling soil C accumulation and loss following permafrost thaw are not well understood. To improve our understanding of these processes, I examined the effects of permafrost thaw on soil C dynamics in forested upland and peatland ecosystems of Alaska's boreal region. In upland forests, soil C accumulation and loss …

Scanning Laser Registration And Structural Energy Density Based Active Structural Acoustic Control, Daniel Alan Manwill Dec 2010

Scanning Laser Registration And Structural Energy Density Based Active Structural Acoustic Control, Daniel Alan Manwill

Theses and Dissertations

To simplify the measurement of energy-based structural metrics, a general registration process for the scanning laser doppler vibrometer (SLDV) has been developed. Existing registration techniques, also known as pose estimation or position registration, suffer from mathematical complexity, instrument specificity, and the need for correct optimization initialization. These difficulties have been addressed through development of a general linear laser model and hybrid registration algorithm. These are applicable to any SLDV and allow the registration problem to be solved using straightforward mathematics. Additionally, the hybrid registration algorithm eliminates the need for correct optimization initialization by separating the optimization process from solution selection. …

Configuration Of The Pleistocene Surface Beneath Cat Island, Mississippi And Implications For Barrier Island Formation And Evolution, Kathryn Rose Dec 2010

Configuration Of The Pleistocene Surface Beneath Cat Island, Mississippi And Implications For Barrier Island Formation And Evolution, Kathryn Rose

LSU New Orleans Theses and Dissertations

The mechanism of Holocene barrier formation aids in determining island geomorphologic responses to modifying climatic processes of the surrounding environment. The geometry and composition of local antecedent topography plays a role in barrier formation by providing an elevated base, nucleus for sedimentation and local sediment supply. Investigation of barriers' subsurface geology provides insight into island formation and evolution. High-resolution shallow seismic data acquired in the island's nearshore zone and interior canals, correlated with existing drillcore data, reveal that Cat Island, MS is situated over an Oxygen Isotope Stage 3 Phase 3 paleochannel located between two topographic high-grounds of the Pleistocene …

Nonattribution Properties Of Jpeg Quantization Tables, Punnya Tuladhar Dec 2010

Nonattribution Properties Of Jpeg Quantization Tables, Punnya Tuladhar

LSU New Orleans Theses and Dissertations

In digital forensics, source camera identification of digital images has drawn attention in recent years. An image does contain information of its camera and/or editing software somewhere in it. But the interest of this research is to find manufacturers (henceforth will be called make and model) of a camera using only the header information, such as quantization table and huffman table, of the JPEG encoding. Having done research on around 110, 000 images, we reached to state that "For all practical purposes, using quantization and huffman tables alone to predict a camera make and model isn't a viable approach". We …

A Web Service For Protein Refinement And Refinement Of Membrane Proteins, Kapil Pothakanoori

LSU New Orleans Theses and Dissertations

The structures obtained from homology modeling methods are of intermediate resolution 1-3Ã… from true structure. Energy minimization methods allow us to refine the proteins and obtain native like structures. Previous work shows that some of these methods performed well on soluble proteins. So we extended this work on membrane proteins. Prediction of membrane protein structures is a particularly important, since they are important biological drug targets, and since their number is vanishingly small, as a result of the inherent difficulties in working with these molecules experimentally.

Effective Ionic Conductivity Of A Novel Intermediate-Temperature Mixed Oxide-Ion And Carbonate-Ion Conductor, Xue Li, Guoliang Xiao, Kevin Huang Dec 2010

Effective Ionic Conductivity Of A Novel Intermediate-Temperature Mixed Oxide-Ion And Carbonate-Ion Conductor, Xue Li, Guoliang Xiao, Kevin Huang

Faculty Publications

A systematic investigation on the effective ionic conductivity (σm) of a novel intermediate-temperature mixed oxide-ion and carbonate-ion conductor MOCC consisting of a ceria phase and a carbonate phase is reported. The study explicitly shows that the observed remarkable temperature-dependent σm is primarily the result of softening/melting of the carbonate phase as the physical state of the carbonate phase transforms from solid, softened to molten. Differential scanning calorimetry analysis complements the understanding of the observed electrical behavior by revealing temperatures of melting and solidification in agreement with the onset temperatures of σm. In addition, the …

Reconciling Motor Performance Indicators From Theoretical Calculations And Laboratory Tests, Himanshu Hirlekar, Badrul H. Chowdhury, Stephen Ruffing

Electrical and Computer Engineering Faculty Research & Creative Works

Quite often because of the complexity in the design of large industrial motors, the theoretical motor parameter calculations do not match actual results from laboratory tests. Thus, it becomes important to predict the amount of discrepancy between the two methods to develop confidence in the motor parameter calculations. This paper discusses the development of multiple artificial neural networks (ANNs) designed to predict the ratios of measured parameters to calculated parameters, given the geometry and construction of the motor. These ratios represent correction factors which can be applied to the values calculated from the theoretical program, which, in this case, is …
