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 …

A Test Of General Strain Theory: Suicidal Ideation And Attempt Among Adolescents In Istanbul, Turkey, Muhammed Yildiz Jan 2015

A Test Of General Strain Theory: Suicidal Ideation And Attempt Among Adolescents In Istanbul, Turkey, Muhammed Yildiz

LSU Master's Theses

Previous suicidal ideation and attempt are the strongest predictors of subsequent completed suicide, which is the second leading cause of death among youth today. Research shows that the risk factors for adolescent suicidal behaviors can be grouped into demographic, social, and psychological categories, so a broad theoretical framework is needed to examine the range of these factors’ effects. In this study, Agnew’s general strain theory is tested to explain those suicidal behaviors among adolescents in Istanbul, Turkey. Agnew argued that specific strains were more likely to lead to deviance, therefore a corresponding set of strains are selected. He also argued …

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 …

A Distributed Diffusion-Driven Algorithm For Load Balancing In An Electrical Power Grid, Isaac Abhilash Ayyala Jan 2015

A Distributed Diffusion-Driven Algorithm For Load Balancing In An Electrical Power Grid, Isaac Abhilash Ayyala

LSU Master's Theses

In this thesis we propose a distributed algorithm, based on diffusion, to balance loads on an electrical power grid, while maintaining stable operation (system’s ability to maintain bus voltages within preset bounds). This algorithm, called the Diffusion-driven Distributed Load Balancing (DDLB) algorithm, is implemented on the OMNET++ Discrete Event Simulator and the response of the physical grid is simulated on a load flow program, which together simulate a deployment of the DDLB algorithm on the grid. The electrical grid is represented as a graph whose nodes are buses and whose edges are power lines connecting buses. Each node (except the …

Metacommunity Dynamics And The Biogeography Of Central Louisiana Crayfishes, William Robert Budnick Jan 2015

Metacommunity Dynamics And The Biogeography Of Central Louisiana Crayfishes, William Robert Budnick

LSU Master's Theses

The greatest diversity of crayfishes, especially of rare Orconectes species, is found in the central Louisiana watersheds (Red River, Mermentau, Calcasieu, and Vermillion-Teche), and most species are widely distributed among the drainages. The purpose of this research was to lay groundwork for species distribution and metacommunity modelling for crayfishes in this region. To address this goal, two field studies were performed in the summers of 2013 and 2014, as well as an indoor laboratory study. Analyses of broadly distributed species indicated no significant correlations between species abundances and habitat variables nor any significant environmental gradients for those species. Within-drainage variability …

The Plagues Of Colonialism: Representations Of Suffering In The Colonial And Postcolonial Francophone Algerian Novel From 1950-1966, Benjamin Jack Sparks Jan 2015

The Plagues Of Colonialism: Representations Of Suffering In The Colonial And Postcolonial Francophone Algerian Novel From 1950-1966, Benjamin Jack Sparks

LSU Doctoral Dissertations

The indigenous Francophone Algerian novel dates from the early 1950s and since then has been a political manifestation of uneasiness. The anticolonial undertones of this literature demonstrate the sufferings and harsh realities of life under an oppressive colonial regime; meanwhile the postcolonial novel continues the representation of this suffering through the residual effects of colonialism and the impact of the bloody decolonization war. This dissertation contributes to the discourse regarding suffering as a result of French colonial oppression in light of François Hollande’s official recognition of the trauma of colonialism and the acceptance of the events from 1954-1962 as a …

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 …
