Inverse Spectral Modeling Of Geopotential Fields Over Sedimentary Basins., Michael Terry Angelich Jan 1985

Inverse Spectral Modeling Of Geopotential Fields Over Sedimentary Basins., Michael Terry Angelich

LSU Historical Dissertations and Theses

Interpretation of geopotential data using inverse spectral modeling techniques eliminates the ambiguous results produced by the standard forward-modeling approach. However, applying the spectral modeling procedures by hand is time-consuming and lacks precision. This study expands on current spectral analysis techniques by adding least-squares statistical rigor to the fitting of the chosen model. Automating the model fitting procedure allows an investigator to examine quickly many overlapping sections (windows) of mapped data. Successive overlapping of neighboring windows suggests a correlation between the ensemble-average depth solutions unique to each window is possible. This technique was shown to be especially useful in Louisiana and …

Development Of A Reliable And Valid Diagnostic Assessment Instrument For Migraine And Muscle-Contraction Headaches (Psychometrics, Classification)., Stanford Wayne Granberry Jan 1985

Development Of A Reliable And Valid Diagnostic Assessment Instrument For Migraine And Muscle-Contraction Headaches (Psychometrics, Classification)., Stanford Wayne Granberry

LSU Historical Dissertations and Theses

The reliability and validity of a headache questionnaire, designed as a diagnostic instrument, were investigated. The questionnaire was administered to 117 headache sufferers in individual interviews. Following a 2 week interval the same questionnaire was readministered to 66 of these subjects. All subjects were independently diagnosed by a board certified neurologist and an advanced graduate student in clinical psychology using an Ad Hoc Committee's (1962) criteria. The categories of headache investigated were: muscle-contraction headache (N = 38), combined headache (N = 28), classic migraine (N = 19) and common migraine (N = 32). A factor analysis of the questionnaire data …

Magnetic Anisotropy In The Trenton Limestone: Results Of A New Technique, Anisotropy Of Anhysteretic Susceptibility, Chad Mccabe, Michael Jackson, Brooks B. Ellwood Jan 1985

Magnetic Anisotropy In The Trenton Limestone: Results Of A New Technique, Anisotropy Of Anhysteretic Susceptibility, Chad Mccabe, Michael Jackson, Brooks B. Ellwood

Faculty Publications

A new method for determining magnetic anisotropy using anhysteric remanence susceptibility is described. The magnetic fabric of a collection of Trenton Limestone specimens has been determined using this method, as well as by conventional anisotropy of magnetic susceptibility. The results demonstrate the usefulness of the new method for finding the magnetic fabric of rock units such as the Trenton in which the bulk magnetic susceptibilities are low. A model is proposed to explain the observed foliated and lineated fabric as a consequence of overburden compaction and regional horizontal stresses. The original fabric is inferred to have been isotropic; the anisotropy …

Children's Affective Expression In Human Figure Drawings: Adult Recognition Of Children's Depiction Of Six Affective Expressions., Ralph Darrell Ramsden Jan 1985

Children's Affective Expression In Human Figure Drawings: Adult Recognition Of Children's Depiction Of Six Affective Expressions., Ralph Darrell Ramsden

LSU Historical Dissertations and Theses

The understanding of children's abilities to express affect in drawings of the human figure has clinical and developmental significance, yet is an area that until recently has received relatively minimal research attention. The present study investigated the abilities of child psychologists, graduate psychology students, and non-mental health raters to correctly identify the attempts of 72 kindergarten, second, fourth, sixth, eighth, and tenth-grade students to depict six common affective expressions in human figure drawings. The affective expressions were: happiness, sadness, anger, disgust, surprise, and fear. Thirty-six adult raters (18 female; 18 male) reviewed 216 drawings, identified the perceived affective expression, and …

Literature As Phenomenon: Attribution Theory And The Act Of Performance (Oral, Interpretation, Pre-Formance, Newcomb, Bakhtin)., John Walthall Creagh Iii Jan 1985

Literature As Phenomenon: Attribution Theory And The Act Of Performance (Oral, Interpretation, Pre-Formance, Newcomb, Bakhtin)., John Walthall Creagh Iii

LSU Historical Dissertations and Theses

Attribution theory seeks to explain the ways in which humans ascribe causes to everyday events, especially the observed behavior of other human beings. This study seeks to apply the basic patterns of social attribution to the act of "pre-formance"--the aesthetic act in which a performer engages the voice of a literary text and, through rehearsals involving attribuiton, embodies that voice for some audience. Theodore Newcomb's "symmetry theory," a model that contains the essential features of human attribution, is discussed within the philosophical perspective of phenomenology, and the transformed model is used as the basis for a new theory of the …

Raman Microprobe Determination Of Local Crystal Orientation In Laser Annealed Silicon, J. B. Hopkins, L. A. Farrow, G. J. Fisanick Dec 1984

Raman Microprobe Determination Of Local Crystal Orientation In Laser Annealed Silicon, J. B. Hopkins, L. A. Farrow, G. J. Fisanick

Faculty Publications

In this letter we discuss the application of polarization selective Raman microprobe spectroscopy to the detailed, nondestructive analysis of the local crystal orientation of a polycrystalline silicon sample grown over SiO 2 pads and laser annealed. Intensity measurements taken as a function of input polarization angle are fit to an expression derived from the Raman scattering selection rules to calculate the angles by which the crystal structure is twisted within the original substrate plane, as well as the degree of tipping of the crystal plane away from the plane of the Si substrate.

A Fluid Inclusion Study Of Diagenetic Mineral Phases, Upper Jurassic Smackover Formation, Southwest Arkansas And Northeast Texas, Terrence Clark O'Hearn Aug 1984

A Fluid Inclusion Study Of Diagenetic Mineral Phases, Upper Jurassic Smackover Formation, Southwest Arkansas And Northeast Texas, Terrence Clark O'Hearn

LSU Historical Dissertations and Theses

Homogenization and final melting temperature data from primary and secondary two-phase fluid inclusions within carbonate and sulfate mineral phases reflect the physical re-equilibration of pre-burial calcites and the precipitation of late diagenetic mineral phases during the burial of the upper Smackover (Upper Jurassic, Oxfordian) lime-grainstones in southwestern Arkansas and northeastern Texas. Homogenization temperatures range from 83.0° to 153.8°C (uncorrected for excess ambient formation pressures at time of trapping) . Final melting points range from -33.4° to -13.5°C. Statistically distinct temperature populations reveal the re-equilibration of pre-burial bladed calcite cements and parallel the subsequent paragenesis during burial of non-fabric-selective dolomite, zoned …

Five-Dimensional Quasispin And The Spectra Of Odd-Parity Yrast Configurations In The Ba Region, K. J. Weeks, J. P. Draayer, K. T. Hecht Feb 1984

Five-Dimensional Quasispin And The Spectra Of Odd-Parity Yrast Configurations In The Ba Region, K. J. Weeks, J. P. Draayer, K. T. Hecht

Faculty Publications

The 5-dimensional quasispin formalism is used to evaluate the (n, T)-dependent factors of the matrix elements of abnormal parity operators of relevance for yrast-band spectroscopy. The formalism allows the leading pseudo-SU(3) representation of the normal (N) parity part of a shell-model configuration to be coupled to low-seniority states of the abnormal (A) parity high-j intruder part of the configuration. To illustrate the importance of the nA, TA dependence of the (A) to (N) space-coupling matrix elements this model is applied to the negative-parity yrast spectra of 127La and 127Ba, using hamiltonian parameters which give a reasonable fit for 126Ba.

Factors Affecting The Success/Nonsuccess Of Small Farmers In Louisiana., Adell Brown Jan 1984

Factors Affecting The Success/Nonsuccess Of Small Farmers In Louisiana., Adell Brown

LSU Historical Dissertations and Theses

In Louisiana it was observed that many small farmers survived over long periods of time, while others with similar farm resources did not. The purpose of this study was to evaluate the social and economic factors affecting the degree of success of small farmers. A major objective was to compare two methodologies used in defining and evaluating success on a small farm. The farm business approach as measured by economic performance (quantitative) was compared to the family well-being approach as measured by socio-economic factors (qualitative to determine similarities and differences in classifying successful and nonsuccessful farms. The literature was examined …

A Time Series Model Of The Controller Functions Of The Human Temperature Regulating System., Mohsen Neghabat Jan 1984

A Time Series Model Of The Controller Functions Of The Human Temperature Regulating System., Mohsen Neghabat

LSU Historical Dissertations and Theses

The objective of this study is to develop time series models of the controller mechanisms of the human temperature regulating system. The controller responses are: changes in metabolic heat production, changes in evaporative heat loss and alterations in the surface blood flow. After evaluating the models developed for the controller mechanisms, the models are validated in the context of a complete simulation model of temperature regulation. Additionally, upper and lower limits are set for the controller responses. Because of the nature of the data available for surface blood flow, this controller response is not represented by time series models. Published …

Experimental Investigation Of A Cylinder In Axial Motion At Low Reynolds Number., Tsukasa Jeff Ui Jan 1984

Experimental Investigation Of A Cylinder In Axial Motion At Low Reynolds Number., Tsukasa Jeff Ui

LSU Historical Dissertations and Theses

Measurements were made on the terminal velocity of circular cylinders with length to diameter ratio 4 < L/D < 231 moving parallel to their axes at low Reynolds number in a fluid bounded by a cylindrical container. The drag was found to vary inversely with the boundary diameter as suggested by Wakiya's theory for prolate spheroids. When extrapolated to infinite boundary, the results agree well with the numerical calculations of Youngren and Acrivos, Gluckman et al. and Swanson et al. and the experimental results of Heiss and Coull.

A Regression Model To Measure The Impact Of Actual And Proposed Class Scheduling Policies On Electricity Consumption: A Case Study At Louisiana State University., Enrique Mejorada Jan 1984

A Regression Model To Measure The Impact Of Actual And Proposed Class Scheduling Policies On Electricity Consumption: A Case Study At Louisiana State University., Enrique Mejorada

LSU Historical Dissertations and Theses

Universities have adopted many programs to conserve electricity and counteract its high costs. Electricity can be conserved by adopting a class scheduling policy which schedules a reduced number of classes when the weather is more inclement. A regression model is postulated to measure the impact of the actual class scheduling policy on the 3-hourly electricity consumption at Louisiana State University. This model explicitly considers the effects of students' load, temperature, and humidity, and implicitly considers variables such as electricity prices and implemented electricity conservation programs through dummy variables. Also, two- and three-way interaction effects are considered in this model. Since …

Liver And Egg Yolk Cholesterol Changes Caused By Dietary Lipids., Jesus Perez-Buriel Jan 1984

Liver And Egg Yolk Cholesterol Changes Caused By Dietary Lipids., Jesus Perez-Buriel

LSU Historical Dissertations and Theses

A series of seven short term experiments were conducted using SCWL laying hens to study liver and egg yolk cholesterol changes caused by dietary lipids. For all the experiments, the individually caged layers were 55 week-old or older and automated procedures were used to measure the liver and yolk cholesterol responses. In the first four experiments the diets contained olive or safflower oils at 8%, oleic or linoleic acids at 6%, all with or without cholesterol. In experiment 5, dietary levels of olive and safflower (1 and 8%) and cholesterol (0 and 1%) were factorially combined and examined. The olive …

Herman Frasch (German Immigrant Chemist, Standard Oil, Petroleum; Ohio, Louisiana)., William Ralph Sutton Jan 1984

Herman Frasch (German Immigrant Chemist, Standard Oil, Petroleum; Ohio, Louisiana)., William Ralph Sutton

LSU Historical Dissertations and Theses

Herman Frasch (1851-1914) invented the hot-water process for mining sulphur that permitted the exploitation of the rich deposits beneath the coastal plain of the Gulf of Mexico. The Frasch process enabled the United States to become self-sufficient in the production of this important industrial mineral and the major supplier to the world. Frasch's new idea was to inject steam into the underground deposit to melt the sulphur and then pump the liquid to the surface. He patented the process in 1891 and first demonstrated its technical success at Sulphur, Louisiana in 1894. Initially plagued with problems due to the high …

An In Vitro Evaluation Of The Effect Of Bovine Viral Diarrhea Virus On Preimplantation Bovine Embryos., Charles Richard Looney

LSU Historical Dissertations and Theses

A total of 402 bovine embryos, non-surgically collected on day 6.5-7.5 after estrus, were utilized in evaluation of fluorescein diacetate (FDA) for estimating embryo viability in vitro and to investigate the effect of Bovine Viral Diarrhea (BVD) Virus on embryonic development during in vitro culture. Fluorescent assessment, using UV microscopy (440-480 nm) of embryos after staining in FDA (2.5 (mu)g/ml phosphate buffered saline: PBS), was found to be a rapid, non-toxic and accurate method for evaluation of viability. Embryos with highest fluorescent scores (Score = 4) prior to culture developed at the highest rate (95.7%), while embryos with no fluorescence …

A Study Of The Texture Measurement Definition Problem (Image Analysis)., Ramon Emilio Vasquez-Espinosa Jan 1984

A Study Of The Texture Measurement Definition Problem (Image Analysis)., Ramon Emilio Vasquez-Espinosa

LSU Historical Dissertations and Theses

The problem of texture measurement definition is studied. A theory is presented in order to overcome the problem. This theory includes a conceptual framework for the general measurement definition problem. This framework is based on the concepts of a perceptual transform, a perceptual space, a measurement transform and a similarity transform. Using this conceptual framework and a particular choice for the similarity transform, a set of requirements are defined. These requirements can be used to create a formal method for defining measurements off the GLC matrices. The formal procedure is based on preserving perceptual relationships among textures. To apply this …
