Infield Biomass Bales Aggregation Logistics And Equipment Track Impacted Area Evaluation, Subhashree Navaneetha Srinivasagan
Infield Biomass Bales Aggregation Logistics And Equipment Track Impacted Area Evaluation, Subhashree Navaneetha Srinivasagan
Agribusiness and Biosystems Engineering
Efficient bale stack location, infield bale logistics, and equipment track impacted area were conducted in three different studies using simulation in R. Even though the geometric median produced the best logistics, among the five mathematical grouping methods, the field middle was recommended as it was comparable and easily accessible in the field. Curvilinear method developed (8-259 ha), incorporating equipment turning (tractor: 1 and 2 bales/trip, automatic bale picker (ABP): 8-23 bales/trip, harvester, and baler), evaluated the aggregation distance, impacted area, and operation time. The harvester generated the most, followed by the baler, and the ABP the least impacted area and …

Towards An Intellectual History Of Evolutionary Economics: Competition And Struggle Versus Cooperation And Mutual Aid, John B. Hall, Svetlana Kirdina-Chandler
Economics Faculty Publications and Presentations
Our inquiry considers the origins of Evolutionary Economics by reintroducing a debate that took place in Russia in the 19th and early 20th century. Responses to Charles Darwin’s The origin of Species are considered, especially critiques stressing Darwin’s emphasis upon competition and struggle in natural selection, that can be traced directly to Thomas Robert Malthus. Considering challenging contributions made by several Russian scholars, we place special emphasis upon Peter Kropotkin’s focus on cooperation and “mutual aid” in natural selection and evolution. We then speculate upon the commonality found in the evolutionary views advanced by Kropotkin and his American contemporary, Thorstein …
Oblivion, Michael Stumbras
Oblivion, Michael Stumbras
LSU Master's Theses
I am fascinated by the myriad ways humans construct meaning in the face of existential uncertainty. For the exhibition Oblivion, I endeavor to provide a gallery experience, a body of metaphorically charged functional vessels, and a number of ritualistic accoutrements that address death, futility, and the passage of time as it inexorably flows toward obsolescence. The process of handcraft and the method of firing that I employ highlights the absurdity of the endeavor of the handmade: the seemingly futile and interminable quest for perfection and meaning. This futilitarian pottery exaggerates the errors of the hand and flaunts artifacts of the …

Performance Evaluation Of Virtual Flow Metering Models And Its Application To Metering Backup And Production Allocation, Kahila Mokhtari Jadid
Performance Evaluation Of Virtual Flow Metering Models And Its Application To Metering Backup And Production Allocation, Kahila Mokhtari Jadid
LSU Doctoral Dissertations
In the oil and gas industry, reliable and accurate measurements of the amount of oil, gas and water being produced by individual wells is essential. The production revenue for each well is determined from measured flow rates. Measurement of well production can be achieved by using multiphase flow meters on individual wells. However, the use of such metering technique is not always reliable or economical. As an alternative technique to monitoring individual well performance in real-time, multiphase flow simulators together with pressure and temperature sensors located at different locations in the production systems have been recently deployed to estimate individual …

University Studies Faculty Publications and Presentations
With society’s increasing dependence on technology infrastructure, the importance of securing the computers, networks, data, and algorithms that run our digital and physical lives is becoming critical. To equip the next generation of citizens for the challenges ahead, an effort is underway to introduce security content early in a student’s academic career. It is important that these efforts broaden participation and increase diversity in the field. While many camps and curricula focus on introducing technical content and skills related to cybersecurity, such approaches can prematurely limit how students view career opportunities in the field, potentially limiting those who ultimately pursue …

Terrorist Aesthetics As Ideal Types: From Spectacle To "Vicious Lottery", Marshall Battani, Michaelyn Mankel
Terrorist Aesthetics As Ideal Types: From Spectacle To "Vicious Lottery", Marshall Battani, Michaelyn Mankel
Contemporary Aesthetics (Journal Archive)
This essay builds on Arnold Berleant’s concept of the negative sublime and his less-appreciated image of the vicious lottery to engage the ongoing discussion about the importance of aesthetic analysis for understanding terrorism. Sociological definitions of aesthetics and terrorism are presented as potential tools to aid in the analyses of terrorist aesthetics. Three aesthetic types of terrorism are developed in the tradition of Weberian sociological ideal typification. The article discusses the appropriateness and applicability of that typology for enriching our understanding of terrorism and counterterrorism.
Experience, Knowledge, And Appreciation In The Implicit Aesthetics Of Weather Lore, Mădălina Diaconu
Experience, Knowledge, And Appreciation In The Implicit Aesthetics Of Weather Lore, Mădălina Diaconu
Contemporary Aesthetics (Journal Archive)
[1] Weather sayings are empirical rules for the prediction of weather and have been studied, so far, only by paremiologists and meteorologists. The author argues that they also present interest for environmental aesthetics, and that their aesthetic dimension is not confined to their stylistic qualities and versified form but is mainly based on the experience that underlies them. The analyses of weather lore in English, French, and German emphasize that this pre-modern, expert knowledge produced and still can bring enjoyment and, conversely, that the sources of this aesthetic enjoyment are to a large extent cognitive, even if not scientific by …

Visualizing Morphogenesis With The Processing Programming Language, Avik Patel, Amar Bains, Richard Millet, Tamira Elul
Faculty Publications & Research of the TUC College of Osteopathic Medicine
We used Processing, a visual artists’ programming language developed at MIT Media Lab, to simulate cellular mechanisms of morphogenesis – the generation of form and shape in embryonic tissues. Based on observations of in vivo time-lapse image sequences, we created animations of neural cell motility responsible for elongating the spinal cord, and of optic axon branching dynamics that establish primary visual connectivity. These visual models underscore the significance of the computational decomposition of cellular dynamics underlying morphogenesis.

Serious mental illness (SMI) is disabling, and current interventions are ineffective for many. This exploratory study sought to demonstrate the feasibility of applying topological data analysis (TDA) to resting-state functional connectivity data obtained from a heterogeneous sample of 235 adult inpatients to identify a biomarker of treatment response. TDA identified two groups based on connectivity between the prefrontal cortex and striatal regions: patients admitted with greater functional connectivity between these regions evidenced less improvement from admission to discharge than patients with lesser connectivity between them. TDA identified a potential biomarker of an attenuated treatment response among inpatients with SMI. Insofar …

A protocol for environmental sampling using Continuous Low-level Aquatic Monitoring (C.L.A.M.) C-18 disks is described, along with effective solid phase extraction (SPE) and gas chromatography mass spectrometry (GC/MS) methodology for the determination of atrazine, chlorothalonil, and fipronil in surface water. Average concentrations of atrazine and chlorothalonil inside the Bayou Lamoque freshwater diversion structure for the months …
Impacts Of Enso On Tornado Frequency, Intensity, And Geography Across The Eastern United States, Coryn Ann Collins
Impacts Of Enso On Tornado Frequency, Intensity, And Geography Across The Eastern United States, Coryn Ann Collins
LSU Master's Theses
Tornadoes are a reoccurring severe weather hazard, with the highest rates globally occurring in the central United States. Despite their high frequency in the U.S., the scientific community’s disagreement of tornado activity during varying phases and intensities of the El Niño Southern Oscillation (ENSO) justifies a need for further research. In this study, tornado events from 1950 to 2014 in the U.S. east of the Rocky Mountains were investigated for seven phases of ENSO: strong, moderate, and weak El Niño/La Niña and the neutral phase. A seasonal Niño 3.4 index was used as the definition of ENSO. ENSO influences on …
National Electoral Winners And Losers: Satisfaction With Democracy Predicated On Institutional Context, Casey Newman Knott
National Electoral Winners And Losers: Satisfaction With Democracy Predicated On Institutional Context, Casey Newman Knott
LSU Master's Theses
How does being an electoral winner or loser shape a citizen’s satisfaction with democracy? More importantly, how does the voter’s institutional context moderate this relationship? In this paper, I demonstrate that the institutional context of a democracy interacts with a citizen’s national- level electoral loser status to moderate the relationship between the individual’s status as a loser and her satisfaction with democracy in her country. I also explore the way winning and losing at different levels of representation interact to formulate satisfaction with democracy. Using cross-sectional survey data from the Comparative Study of Electoral Systems nested in 75 different country-election …
Modeling The Influence Of Energy And Climate Megatrends On Future Costs And Benefits Of Marsh Creation In The Mississippi Delta, Adrian R. H. Wiegman
Modeling The Influence Of Energy And Climate Megatrends On Future Costs And Benefits Of Marsh Creation In The Mississippi Delta, Adrian R. H. Wiegman
LSU Master's Theses
Over 25% of Mississippi delta (MRDP) wetlands were lost over the past century. There is currently a major effort to restore the MRDP focused on a 50-year time horizon, a period during which the energy system and climate will change dramatically. I modeled hydraulic dredging to sustain marsh from 2016-2066 and 2016-2100 under a range of scenarios for sea level rise, energy price, and management regimes. A marsh elevation model was calibrated to data from MRDP marshes. I developed a model to simulate dredging costs based on the price of crude oil and a project efficiency factor. Crude oil prices …
Ex-Companions Of Supernovae Progenitors, Zhichao Xue
Ex-Companions Of Supernovae Progenitors, Zhichao Xue
LSU Doctoral Dissertations
Supernovae (SNe) are titanic explosions that end the life of stars. Fast expanding ejecta can create brightness that is comparable to the entire luminosity of the host galaxy for weeks. Eventually, the ejecta run into the ambient medium, creating the so-called supernova remnant (SNR) that fades away in ~ 10,000 years. SNe come from two completely different mechanisms. The Type Ia SNe (SNIa) are powered by thermonuclear runaway when a white dwarf (WD) in a binary system accretes enough mass from a companion star. The Core Collapse supernovae (CCSNe) are massive stars that run out of fuel at the end …

Small modification of this well-known fluophore has been shown to optimize its photophysical and chemical properties. This work mainly focuses on functionalization of BODIPY cores with halogenated atoms, particularly iodine, and their subsequent post-functionalization reactions, mainly cross-coupling reaction and substitutions, for various further applications. Chapter 1 of this dissertation gives a general overview of BODIPYs including their synthetic strategies, post-functionalization, and how BODIPYs are utilized in many biological applications. Chapter 2 mainly focuses on the synthesis and characterization …
Condition Of Birds In Amazonian Rainforest Fragments And Second-Growth Forests, Angelica Maria Hernandez Palma
Condition Of Birds In Amazonian Rainforest Fragments And Second-Growth Forests, Angelica Maria Hernandez Palma
LSU Doctoral Dissertations
Deforestation modifies otherwise intact expanses of forest into small, isolated fragments. In addition to fragmentation, deforestation also creates abrupt forest edges and large areas of regenerating vegetation where land is abandoned after clearing. Understanding how changes in the landscape affect the physical condition of birds is crucial for managing populations in human-modified landscapes. Here I use the biomarkers feather growth rate and feather quality (ptilochronology), fluctuating asymmetry (FA), and stress hormones from feathers (CORT), to estimate the physical condition of Amazonian understory birds living in forest fragments, second-growth forests, and continuous forests. Feather CORT revealed how fragmentation disrupts interspecific interactions; …
Atmospheric Boundary Layer Processes To Mimic Peak Pressures On Low-Rise Buildings: Cfd Versus Full-Scale And Wind Tunnel Measurements, Hamzeh Gol Zaroudi
Atmospheric Boundary Layer Processes To Mimic Peak Pressures On Low-Rise Buildings: Cfd Versus Full-Scale And Wind Tunnel Measurements, Hamzeh Gol Zaroudi
LSU Doctoral Dissertations
Realistic prediction of peak wind pressures is indispensable in a safe design of low-rise buildings. For several decades wind tunnel testing was employed to obtain wind loads on buildings and other structures. However, there is still doubt in the wind engineering community regarding the adequacy of wind tunnels to predict accurately full-scale pressures on low-rise buildings and small-size structures. The recommendations of the American Society of Civil Engineers (ASCE) 7-10 standard for external pressure coefficients, for roof components and cladding (C&C) design are also based on published wind tunnel data. Recent field measurements show significant deviation of full-scale pressures from …
Maintaining High Performance Across All Problem Sizes And Parallel Scales Using Microkernel-Based Linear Algebra, Md Rakib Hasan
Maintaining High Performance Across All Problem Sizes And Parallel Scales Using Microkernel-Based Linear Algebra, Md Rakib Hasan
LSU Doctoral Dissertations
Linear algebra underlies a large proportion of computational problems. With the continuous increase of scale on modern hardware, performance of small sized linear algebra has become increasingly important. To overcome the shortcomings of conventional approaches, we employ a new approach using a microkernel framework provided by ATLAS to improve the performance of a few linear algebra routines for all problem sizes. Our initial research consists of improving the performance of parallel LU factorization in ATLAS for which we were able to achieve up to 2.07x and 2.66x speedup for small problems, up to 91% and 87% of theoretical peak performance …
Resonant Interactions In Strong Field Laser Physics, Seth Jacob Camp
Resonant Interactions In Strong Field Laser Physics, Seth Jacob Camp
LSU Doctoral Dissertations
We present a theoretical study of the influence of resonant enhancement on high harmonic generation for harmonics near the ionization threshold of helium and argon atoms. This is done by solving the time-dependent Schrodinger equation (TDSE) for the interaction between an atom and a driving laser pulse. By varying parameters of the driving laser pulse, we are able to identify the enhancement of harmonics resulting from multiphoton resonances between the ground state and Stark-shifted excited states of the atom. In this way, spectral and temporal signatures of resonant enhancement are identified and highlighted. We also study trajectory dynamics in HHG. …
Characterizing The Hydrodynamics Of A Meandering River Neck Cutoff, Christopher Turnipseed
Characterizing The Hydrodynamics Of A Meandering River Neck Cutoff, Christopher Turnipseed
LSU Master's Theses
Meandering river systems often experience a geomorphic phenomenon known as a neck cutoff. The White River of Arkansas has recently undergone several neck cut offs, which have provided a unique opportunity to collect field measurements of the first two years after the opening of the cutoff. In this study the field data was complemented with hydrodynamic simulations to assess the significance of different flow conditions. The findings suggest that flood events play a substantial role in the geomorphic adjustment of the river to the cutoff.
Nanoscale Studies Of Proteins And Thin Films Using Scanning Probe Microscopy, Zachary Lane Highland
Nanoscale Studies Of Proteins And Thin Films Using Scanning Probe Microscopy, Zachary Lane Highland
LSU Doctoral Dissertations
Nanostructures of organosilanes, thin metal films, and protein nanopatterns were prepared and analyzed with atomic force microscopy (AFM). Organosilanes with designed functional groups were used to selectively pattern green fluorescent protein at the nanoscale using protocols developed with particle lithography. Mesospheres are deposited onto a substrate to produce a surface mask. Organosilanes are deposited to form a matrix film surrounding nanopores for depositing proteins. The nanopatterns were characterized using AFM, after steps of particle lithography for directly visualizing surface changes. Studies with AFM also provide a compelling tool for teaching undergraduates to introduce concepts of nanoscience. An undergraduate laboratory was …

In Search Of Antarctica's Last Vegetation Refugium Within The Mcmurdo Dry Valleys, David Rau
LSU Master's Theses
The McMurdo Dry Valleys, a hyper-arid cold polar desert located within the Transantarctic Mountains was once covered by vegetation. An in depth study of surface samples of various Neogene age, acquired throughout the Valleys, provide insight to the location of one of Antarctica’s last vegetation refugia. Boston University’s Antarctic Research Group has collected 82 surface samples from paleo lake sediments on 14 expeditions spanning 22 years in the McMurdo Dry Valleys. The ages of the samples are still not fully constrained, but 8 regions where samples were collected have been interpreted to range between 16.95 ± 0.17 to 4 Ma …

The dynamics of the Greenland Ice Sheet and drift of sea ice from the Arctic Ocean reaching Denmark Strait are poorly constrained. We present data on the provenance of Fe oxide detrital grains from two cores in the Denmark Strait area and compare the Fe grain source data with other environmental proxies in order to document the variations and potential periodicities in ice-rafted debris delivery during the Holocene. Based on their Fe grain geochemistry, the sediments can be traced to East Greenland sources and to more distal sites around the Arctic Basin. On the Holocene time scales of the two …

Do Direct Behavior Rating-Single Item Scales (Dbr-Sis) Help Students With Attention Deficit Hyperactivity Disorder Self-Regulate?, Regina M. Hildenbrand-Moore
All-Inclusive List of Electronic Theses and Dissertations
As accountability of teachers has been pushed to the forefront, it has been speculated that tolerance for students with behavior problems will dissipate (Menzies & Lane, 2011). Strategies that are efficient and effective are needed to help monitor behavior change and to help students learn to regulate their behavior. Attention-Deficit/Hyperactivity Disorder (ADHD) is the most common disorder of self-regulation (Barkley, 1997). An estimated three million children in the United States take medications for attention and behavior problems associated with deficits in self-regulation (Olfson, Marcus, Weissman, & Jensen, 2002). Self-regulation interventions have been proposed as methods that are effective in increasing …
