Blind Fault Detection Using Spectral Signatures, Pallavi Chethan Jan 2003

Blind Fault Detection Using Spectral Signatures, Pallavi Chethan

LSU Master's Theses

This work studies a blind fault detection method, which only analyses a system's output signal for any change in the characteristics from pre-fault to post-fault to identify the occurrence of faults. In our case the fault considered to develop the procedure is change in time constant of an aircraft's aileron-actuator system and its simplified version - a position servo system. The method is studied as an alternative to conventional fault detection and identification methods. The output signal is passed through a filter bank to enhance the effect of a fault. The Short time Fourier transform is performed on the enhanced …

Molecular Beacon Sequence Design Algorithm, W. Todd Monroe, Frederick R. Haselton Jan 2003

Molecular Beacon Sequence Design Algorithm, W. Todd Monroe, Frederick R. Haselton

Faculty Publications

A method based on Web-based tools is presented to design optimally functioning molecular beacons. Molecular beacons, fluorogenic hybridization probes, are a powerful tool for the rapid and specific detection of a particular nucleic acid sequence. However, their synthesis costs can be considerable. Since molecular beacon performance is based on its sequence, it is imperative to rationally design an optimal sequence before synthesis. The algorithm presented here uses simple Microsoft® formulas and macros to rank candidate sequences. This analysis is carried out using mfold structural predictions along with other free Web-based tools. For smaller laboratories where molecular beacons are not the …

Resistant Rice Starch Development, Siow Ying Tan Jan 2003

Resistant Rice Starch Development, Siow Ying Tan

LSU Master's Theses

This study showed that enzyme treatments were effective in producing resistant starch from rice flour and starch. Rice starch produced higher resistant starch yields than rice flour. The lower resistant starch yields in rice flour could be attributed to the presence of lipids and proteins which were competitively binding to amylose, resulting in decreased recrystallization of amylose. The gelatinization type and incubation periods were not as influential as enzyme treatments in the resistant starch formation. The rapid visco amylograph (RVA) analysis indicated that the gelatinized samples have minimal pasting characteristics since they had been gelatinized prior to enzyme treatments. Pasting …

Rhizome Manipulation Affects Growth And Development Of Ornamental Gingers, Maria Del Pilar Paz Jan 2003

Rhizome Manipulation Affects Growth And Development Of Ornamental Gingers, Maria Del Pilar Paz

LSU Master's Theses

Ornamental gingers are popular cut flowers and have been promoted as a promising potted flower crop because of unique foliage, long-lasting colorful bracts, and few pest problems. Rhizomes are the primary means of propagation in late spring followed by shoot growth and flowering, and plants enter dormancy under short days in the fall. Termination of dormancy is important for greenhouse forcing and extending the growing season. Rhizomes of five ginger species (Curcuma alismatifolia Gagnep., C. cordata L., C. roscoeana Wallich, Globba winittii C.H. Wright, and Kaempferia galanga L.) were either: 1) stored for 0 to 16 weeks at 15, 20 …

Bombarding The City Of The Dead: Who Has A Right To The Past?, Corey David Hotard

LSU Master's Theses

This study focuses on the relationship between tourism and archaeology at Saint Louis Cemetery Number One in New Orleans. In the past two decades, the discipline of archaeology has been thrust into the gaze of the public. The Information Age has led to the increased accessibility of archaeological sites to anyone who may have an interest. Due to this increased accessibility, professional archaeologists have turned to public archaeology in order to satiate the public’s curiosity. Although public archaeology is a growing field, a good bit of the subject still deals mainly with legislation and preservation rather than direct contact with …

"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle Jan 2003

"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle

LSU Master's Theses

This thesis claims that Shakespeare exaggerated the characterization of two figures in Romeo and Juliet, Friar Laurence and the apothecary, to make a statement about the conditions of medical treatment in sixteenth century London. These two figures represent two very different approaches to healing, one that is informed with ancient holistic medical theory and one that is driven by economics, and this work attempts to explain the cultural conditions that warranted such a discrepancy in the play. I address these two medical figures in the contexts of the events of the text, of the contemporary medical profession, and of materialism …

A Comparison Of Finfish Assemblages On Subtidal Oyster Shell (Cultched Oyster Lease) And Mud Bottom In Barataria Bay, Louisiana, John Plunket Jan 2003

A Comparison Of Finfish Assemblages On Subtidal Oyster Shell (Cultched Oyster Lease) And Mud Bottom In Barataria Bay, Louisiana, John Plunket

LSU Master's Theses

Recent research suggests that oyster reefs provide unique three-dimensional hard bottom habitat for many fish species. Along the northern shore of the Gulf of Mexico, oyster shell bottoms are predominantly flat, subtidal and cultched, lacking the vertical relief and spatial heterogeneity provided by natural reefs. This study compared finfish assemblages, gut contents, and macroinvertebrate assemblages at subtidal oyster shell (cultched oyster lease) and mud bottoms in Barataria Bay, Louisiana. Three mud and three shell sites were sampled on seven dates from October 2001 to October 2002, using gill nets and substrate trays. Data from the gill nets were used to …

Ultrasonic Characterization Of Engineering Performance Of Oriented Strandboard, Ronnie Yunheu Vun Jan 2003

Ultrasonic Characterization Of Engineering Performance Of Oriented Strandboard, Ronnie Yunheu Vun

LSU Doctoral Dissertations

Direct-contact (DC) and non-contact (NC) ultrasonic transmission (UT) methods were developed to characterize the structural performance of oriented strandboard (OSB). The UT variable velocity was shown to be sensitive to the physical impediments caused by flake interfacial boundaries and embedded voids. Both attenuation and root mean square (RMS) voltage were good indicators of the “zero void” densification level for OSB, a point of the greatest transmissivity of the stress wave energy. For both DC and NC methods, the predicted densities of the model were validated for spatial distribution over each OSB type. Based on the EN300 standard for panel manufacturing, …

The Use Of The Bang-3 Polymer Gel To Quantify The Three-Dimensional Dose Distribution Of Imrt, Paul Anthony Bruce Jan 2003

The Use Of The Bang-3 Polymer Gel To Quantify The Three-Dimensional Dose Distribution Of Imrt, Paul Anthony Bruce

LSU Master's Theses

The sophistication of radiation therapy delivery techniques at Mary Bird Perkins Cancer Center (MBPCC) creates the need for an advanced dosimetric system that can quantify and verify the dose distributions in three-dimensions. Current dosimetric systems perform this dose analysis in only one or two dimensions. This paper evaluates the application of BANG-3™ polymer gel dosimetry to quantify the 3-D dose distribution of Intensity-Modulated Radiation Therapy (IMRT) using a "step and shoot" approach. The gel was irradiated by 10 MV photons at a dose rate of 400 MU/min. Relaxation rate maps were computed from proton density and T2-weighted magnetic …

Using Trabecular Architecture Of The Proximal Femur To Determine Age At Death: An Accuracy Test Of Two Methods, Wendy Michelle Jones Jan 2003

Using Trabecular Architecture Of The Proximal Femur To Determine Age At Death: An Accuracy Test Of Two Methods, Wendy Michelle Jones

LSU Master's Theses

Osteologists and forensic researchers are often called upon to determine age at death for skeletal remains. Although there are common methods in wide use, new methods are always sought. This study evaluates the accuracy of two radiographic methods of determining age by looking at the changes in the trabecular architecture of the proximal femur. These two methods are the Szilvassy and Kritscher (1990) method and the Walker and Lovejoy (1985) method. Samples were taken from four skeletal collections. Radiographs were taken of each individual and both Szilvassy and Kritscher’s (1990) phases of trabecular change and Walker and Lovejoy’s (1985) phases …

The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich Jan 2003

The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich

LSU Master's Theses

Vaccination programs are designed to protect an animal from infection, however, depending upon the age and health of the animal vaccination may not stimulate a protective humoral response. It is possible that, as in the human and mouse models, geriatric equines may be less responsive than their younger counterparts to current vaccination protocols. The purpose of this study was to identify an age related diminution in the primary and secondary immune responses of geriatric horses in response to vaccination. Two groups of horses were sampled. The first group consisted of an open herd of 39 privately owned horses, varying in …

Exploring Geometric, Kinematic And Behavioral Scalability Of Microscopic Traffic Simulation Systems, Srikanth Chakravarthy Jan 2003

Exploring Geometric, Kinematic And Behavioral Scalability Of Microscopic Traffic Simulation Systems, Srikanth Chakravarthy

LSU Master's Theses

Even with today's remarkable advancement in computing power, microscopic simulation modeling remains a computationally intensive process that imposes limitations on its potential use for modeling large-scale transportation networks. Research and practice have repeatedly demonstrated that microscopic simulation runs can be excessively time-consuming, depending on the network size, the number of simulated entities (vehicles), and the computational resources available. While microscopic features of a simulated system collectively define the overall system characteristics, it is argued that the microscopic simulation process itself is not necessarily free of redundancy, which if reduced, could substantially improve the computational efficiency of simulation systems without compromising …

A Risk-Averse Strategy For Blackjack Using Fractional Dynamic Programming, Ryan A. Dutsch Jan 2003

A Risk-Averse Strategy For Blackjack Using Fractional Dynamic Programming, Ryan A. Dutsch

LSU Master's Theses

We present how blackjack is related to a discrete-time control problem, rather than a zero-sum game. Using the compiler Visual C++, we write a program for a strategy for blackjack, but instead of maximizing the expected value, we use a risk-averse approach. We briefly describe how this risk-averse strategy is solved by using a special type of dynamic programming called fractional dynamic programming.

Evaluation Of Mechanical Fitness For Service Of High Temperature Hydrogen Attacked Steels, Brent Matthew Saba Jan 2003

Evaluation Of Mechanical Fitness For Service Of High Temperature Hydrogen Attacked Steels, Brent Matthew Saba

LSU Master's Theses

A novel approach is introduced in evaluating one of industry’s most complex corrosion phenomena, high temperature hydrogen attack (HTHA). Limited efforts have been made by industry to address this degradation mechanism and even less data are available to properly utilize their evaluation techniques. The predominant fracture mechanics based analysis of HTHA relies on Charpy V-Notch (CVN) impact test data. In the face of limited CVN test data, accurate results are shaky at best. The HTHA evaluation set forth in this paper combines the analysis tools of plastic collapse and both static and dynamic fracture mechanics. The first condition addresses plastic …

Modeling A Mississippi River Diversion Into A Louisiana Wetland, Stephan Alexander Capps Jan 2003

Modeling A Mississippi River Diversion Into A Louisiana Wetland, Stephan Alexander Capps

LSU Master's Theses

Wetland loss has significant impacts. Numerous loss mechanisms have been hypothesized, and a greater number of solutions have been proposed. One proposed solution is to divert river water into a degraded area with the intent of increasing sedimentation, introducing nutrients, and/or decreasing salinity within the wetland. However, wetland hydraulics and hydrology are complex processes and any hydrologic modification may result in unintended consequences. Predicting these consequences can be problematic due to the complexity and difficulty associated with proper modeling of the hydraulics and topography. The primary objective of this study is to evaluate the suitability of established one- and two-dimensional …

Disarming The Externalist Threat To Self-Knowledge, Gabriel Guy Cate Jan 2003

Disarming The Externalist Threat To Self-Knowledge, Gabriel Guy Cate

LSU Master's Theses

The purpose of this thesis is to examine various attempts to disarm the externalist threat to self-knowledge. That threat is engendered by a certain causal theory of meaning and reference, which suggests that empirical investigations may be required to know the contents of our own thoughts. It is claimed, then, that direct, non-inferential self-knowledge of our own mental states, is not possible if externalism is true. The leading compatibilist strategies that attempt to reconcile these apparently conflicting theses are explored and criticized. I conclude by offering what I take to be the essential features of a more successful compatibilist strategy.

A Disjoining Pressure For Small Contact Angles And Its Applications, Qingfang Wu Jan 2003

A Disjoining Pressure For Small Contact Angles And Its Applications, Qingfang Wu

LSU Master's Theses

A thin liquid film experiences additional intermolecular forces when the film thickness h is less than roughly 100 nm. The effect of these intermolecular forces at the continuum level is captured by the disjoining pressure . Since dominates at small film thicknesses, it determines the stability and wettability of thin films. To leading order, a thin film can be treated as uniform and . This form, however, cannot be applied to films with non-zero contact angles. A recent ad-hoc derivation to include the slope leads to a that allows a contact line to move without slip.
