Image-Based Modeling Of Porous Media Using Fem And Lagrangian Particle Tracking, Paula Cysneiros Sanematsu Jan 2015

Image-Based Modeling Of Porous Media Using Fem And Lagrangian Particle Tracking, Paula Cysneiros Sanematsu

LSU Doctoral Dissertations

The study of fundamental flow and transport processes at the pore scale is essential to understanding how the mechanisms affect larger, field-scale, processes that occur in oil and gas recovery, groundwater flow, contaminant transport, and CO2 sequestration. Pore-scale imaging and modeling is one of the techniques used to investigate these fundamental mechanisms. Although extensive development of pore-scale imaging and modeling has occurred recently, some areas still need further advances. In this work, we address two areas: (1) imaging of bulk proppants and proppant-filled fractures under varying loading stress and flow simulation in these systems and (2) nanoparticle (NP) transport modeling …

The Cost Of Design: A Life-Cycle Assessment Of Green Infrastructure Technology, Cheryl Kaye Lough Jan 2015

The Cost Of Design: A Life-Cycle Assessment Of Green Infrastructure Technology, Cheryl Kaye Lough

LSU Master's Theses

Landscape architectural research of green infrastructural practices has increased dramatically over the last decade. Due to this research, many designers are suggesting some form of green infrastructure within their projects. Much of the present-day research focuses on function and not long term impacts of individual materials. The current rate of implementation of green infrastructures might not produce a drastic impact upon the environment, but with installations being realized at an ever-increasing and larger scales, even minute elements within the construction of these structures begin to influence the overall ecological footprint produced by our designs. Designers must re-evaluate the materiality of …

Nationalization And Regionalism In 1920s College Football, Bennett Jeffery Koerber Jan 2015

Nationalization And Regionalism In 1920s College Football, Bennett Jeffery Koerber

LSU Master's Theses

By illuminating the complexities of 1920s American society, college football serves as a remarkably insightful cultural device. At the commencement of the decade, a national business community – one that had been developing since the late nineteenth century – appeared to have come to fruition. The more connected nature of the country served to homogenize the United States economically, politically, and even socially. Citizens who had once lived autonomously found themselves more interconnected with neighboring regions of the country, and thus increasingly defined by national characteristics. This served as an internal crisis of sorts because regional identity operated as a …

Language Processing And The Artificial Mind: Teaching Code Literacy In The Humanities, Jerry Scott Weltman Jan 2015

Language Processing And The Artificial Mind: Teaching Code Literacy In The Humanities, Jerry Scott Weltman

LSU Master's Theses

Humanities majors often find themselves in jobs where they either manage programmers or work with them in close collaboration. These interactions often pose difficulties because specialists in literature, history, philosophy, and so on are not usually "code literate." They do not understand what tasks computers are best suited to, or how programmers solve problems. Learning code literacy would be a great benefit to humanities majors, but the traditional computer science curriculum is heavily math oriented, and students outside of science and technology majors are often math averse. Yet they are often interested in language, linguistics, and science fiction. This thesis …

Metamorphoses Of The Pygmalion Myth In French Literature 1771 – 1886, Carrie L. O'Connor Jan 2015

Metamorphoses Of The Pygmalion Myth In French Literature 1771 – 1886, Carrie L. O'Connor

LSU Doctoral Dissertations

Writers have long explored and attempted to portray the visual artist’s challenge of creating the ideal in the real world through art. My thesis asserts that the Pygmalion myth, originally told in written form in Ovid’s 8 A.D. Metamorphoses, is the quintessential model to explore the changing, and sometimes problematic, relationships between the artist, the creation, and the creative process. The three main characters in the Pygmalion myth – the sculptor, the sculpture, and the divine intervention – each appear, albeit in different manifestations, in its later adaptations. Throughout the late eighteenth and nineteenth centuries in French literature, authors explored …

The Unattainable Ideal: Walter Lippmann And The Limits Of The Press And Public Opinion, Amy Solomon Whitehead Jan 2015

The Unattainable Ideal: Walter Lippmann And The Limits Of The Press And Public Opinion, Amy Solomon Whitehead

LSU Master's Theses

Walter Lippmann’s classic work, Public Opinion, crystallized thinking about the dynamic relationship between the press and public opinion, and clarified the role of each in democracy. Evaluations of that book, however, tend to be one-dimensional. Public Opinion captured just one iteration of his thinking on the subject, not his final statement on the matter. A comprehensive survey of his writing reveals Lippmann’s views on the press and public opinion were not static, yet the attention Public Opinion receives continues to overshadow his other works; his evolving views on the press and public opinion are rarely mentioned. Although his views shifted …

Using Stormwater Modeling In Iterative Site Design: An Integration Of Techniques From Engineering And Landscape Architecture, Brooke Erin Morris Jan 2015

Using Stormwater Modeling In Iterative Site Design: An Integration Of Techniques From Engineering And Landscape Architecture, Brooke Erin Morris

LSU Master's Theses

Landscape Architects currently do not have an efficient method for including stormwater quantities in early stages of their design process. With stormwater control infrastructure and theory rapidly shifting in favor of stormwater management with Green Infrastructure or Low Impact Development technologies (LIDs), landscape architects and planners are increasingly making layout and sizing decisions for stormwater design. Due to the development of modeling tools, it is now possible to rapidly produce quantifiable stormwater values for complex site designs at a range of scales. This paper proposes a methodology for the utilization of the EPA – Stormwater Management Model (SWMM), in conjunction …

Beyond Batterers: A Primary Prevention And Adult Learning Approach To Engage Well-Meaning Men To Prevent Violence Against Women, Lorett Sturgill Swank Jan 2015

Beyond Batterers: A Primary Prevention And Adult Learning Approach To Engage Well-Meaning Men To Prevent Violence Against Women, Lorett Sturgill Swank

LSU Doctoral Dissertations

This purpose of this research is to examine the critical issue of intimate partner violence and to explore a how non-battering “well-meaning men” can help to end this violence against women. Domestic violence has been primarily considered a women’s issue, and current efforts to prevent this violence have been led mostly by women. In spite of these efforts, violence against women still persists and “well-meaning men” have not been part of a proactive solution. This growing movement to engage men in preventing violence against women, empowers men to learn about and identify the issues that support a culture that tolerates …

A Quantitative Study Using Constructist Learning Activities To Connect Biology Concepts To Local Environmental Issues In A Non-Major Introductory College Biology Course, Michaelyn Broussard

LSU Doctoral Dissertations

Among the general population, there has continued to be a struggle to improve environmental literacy with the knowledge, attitude, and awareness of basic environmental issues locally and nationally. Despite efforts through many formal and informal programs, the result nationally has indicated little to no understanding of basic environmental issues (Coyle, 2005). Many educators such as Sobel (1996, 2004) and Louv (2005) have documented the lack of positive outdoor experiences or environmental behaviors. The purpose of this study was to incorporate local environmental examples through constructivist learning techniques within a general biology non-major course to promote an increase in environmental literacy …

Multiscale Modeling Of Particle Transport In Petroleum Reservoirs, Layne Bryan French Jan 2015

Multiscale Modeling Of Particle Transport In Petroleum Reservoirs, Layne Bryan French

LSU Master's Theses

Modeling subsurface particle transport and retention is important for many processes, including sand production, fines migration, and nanoparticle injection. In this study, a pore-scale particle plugging simulator is concurrently coupled with a streamline reservoir simulator to predict the behavior of particles in the subsurface. The coupled simulators march forward in time together. The automated communication between the two models enables the prediction of spatially and time dependent parameters that control the particle transport process. At each time step, the reservoir simulator provides the inlet velocity and particle concentration of the fluid suspension to the pore-scale model which outputs the permeability, …

Impact Of Algae On Sugar Mill Effluents: Water Treatment And Added Value Assessment, Jacob Stephen Foy Jan 2015

Impact Of Algae On Sugar Mill Effluents: Water Treatment And Added Value Assessment, Jacob Stephen Foy

LSU Master's Theses

Installations similar to Louisiana sugar mills have been proposed as potential biorefineries for sugarcane, energy cane, and sweet sorghum. The nutrient-rich wastewater generated from the milling process can be used as an algal growth medium. Simultaneously, algae can serve as a water treatment strategy to deplete these effluents of excess nitrogen, phosphorus, and organic carbon. In this research the effluents of a sugar mill were characterized for water quality and nutrient characteristics; the effluents were determined to be suitable for growth of a native Louisiana co-culture of microalgae and cyanobacteria (Chlorella vulgaris/Leptolyngbya sp.); growth rate, biomass productivity and nutrient uptake …

Expertise And Disbelief: Post-1945 American Attitudes Toward The Authority Of Knowledge, Terry Wagner Jan 2015

Expertise And Disbelief: Post-1945 American Attitudes Toward The Authority Of Knowledge, Terry Wagner

LSU Doctoral Dissertations

“You can’t beat brains,” said President John Kennedy of the intellectuals and technicians he assembled in his cabinet. Kennedy was perhaps the greatest political champion for the virtues of expertise. However, all over America during the 1960s and ‘70s, diverse groups voiced doubts about how much experts, such as social scientists, policy specialists, and others, actually improved life. This dissertation examines how movements on the political left and right, and spiritual ruptures such as the rise of ‘60s counterculture and of evangelicalism, spoke in different language to express a similar point: human mastery over the world is profoundly limited. Many …

Analysis Of Nonlinear Dispersive Model Equations, Jacob Grey Jan 2015

Analysis Of Nonlinear Dispersive Model Equations, Jacob Grey

LSU Doctoral Dissertations

In this work we begin with a brief survey of the classical fluid dynamics problem of water waves, and then proceed to derive well known evolution equations via a Hamiltonian Variational approach. This method was first introduced in the seminal work of Walter Craig, et al. \cite{CG}. The distinguishing feature of this scheme is that the Dirichlet-Neumann operator of the fluid domain appears explicitly in the Hamiltonian. In the second and third chapters, we utilize the Hamiltonian perturbation theory introduced in \cite{CG} to derive the Benjamin-Bona-Mahony (BBM) and Benjamin-Bona-Mahony-Kadomtsev-Petviashvili (BBM-KP)equations. Finally, we briefly review the existence theory for their corresponding …
