Simulation Study Of Sweep Improvement In Heavy Oil Co2 Floods, Venu Gopal Rao Nagineni Jan 2011

Simulation Study Of Sweep Improvement In Heavy Oil Co2 Floods, Venu Gopal Rao Nagineni

LSU Master's Theses

Enhanced oil recovery by CO2 injection is a common application used for light oil reservoirs since CO2 is relatively easily miscible with light oils. CO2 flooding in heavy oil reservoirs is often uneconomic due to unfavorable mobility ratios. Reservoir heterogeneity further complicates the process as CO2 channels through high permeability layers leading to premature breakthrough. However, this can be controlled by choosing a suitable modification to the CO2 injection process enabling better sweep efficiencies, and making the process economic. The current work focuses on two such methods; water-alternating-gas injection (WAG) and profile modification by blocking gas flow in the high …

An Examination Of The Relationship Between Communication And Socialization Deficits In Infants And Toddlers With Autism And Pervasive Developmental Disorder-Not Otherwise Specified (Pdd_Nos), Megan Alice Hattier

LSU Master's Theses

Autism Spectrum Disorders (ASDs) are characterized by pervasive impairments in repetitive behaviors or interests, communication, and socialization. As the onset of these features occurs at a very young age, early detection is of the utmost importance. In an attempt to better clarify the behavioral presentation of communication and socialization deficits to aid in early assessment and intervention, impairments in these areas were examined among infants and toddlers (17-37 months) with Autistic Disorder (AD), Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS), and non-ASD related developmental delay. The Baby and Infant Screen for Children with aUtIsm Traits-Part1 (BISCUIT-Part1) and the Battelle …

Efficient Replica-Exchange Across Distributed Production Infrastructure, Abhinav S. Thota Jan 2011

Efficient Replica-Exchange Across Distributed Production Infrastructure, Abhinav S. Thota

LSU Master's Theses

Replica-Exchange (RE) methods represent a class of algorithms that involve a large number of loosely-coupled ensembles and are used to understand physical phenomena -- ranging from protein folding dynamics to binding affinity calculations. We develop a framework for RE that supports different replica pairing and coordination mechanisms, that can use a wide range of production cyberinfrastructure concurrently. Additionally, our framework uses a flexible pilot-job implementation, which enables effective resource allocation for multiple replicas. We characterize the performance of two different RE algorithms - synchronous and asynchronous - at unprecedented scales on production distributed infrastructure (Teragrid and LONI). The synchronous RE …

Development And Validation Of Biomechanical Models To Quantify Horse Back Forces At The Walk In Three Horse Breeds, Laxmi Raghunandana Kaidapuram

LSU Master's Theses

Therapeutic horseback riding is a common component of physical therapy programs. Quantification of the horse back forces will provide vital information to match therapeutic riders with equine partners. To meet this medical need, a model to quantify the horse back forces from ground reaction forces was developed to test the hypothesis that the forces transferred to a static weight on the horse’s back can be predicted given horse breed and weight. Simultaneous, real time kinetic, kinematic, and back force data on a static weight were collected from 7 adult horses: 3 thoroughbreds, 3 quarter horses, and 1 paso fino. An …

I Can Has Thesis? A Linguistic Analysis Of Lolspeak, Jordan Lefler Jan 2011

I Can Has Thesis? A Linguistic Analysis Of Lolspeak, Jordan Lefler

LSU Master's Theses

Lolspeak, which I characterize as an internet dialect of English that is used in conjunction with images of cats, exhibits distinctive variations and patterns which differ from those of standard English. Lolspeak has influenced other language use and may have a significant impact on the English language, due in part to the internet’s role in the evolution of English (Crystal “Language and the Internet,” 2006:26-27). To approach this data, I created a multi-modal discourse transcription technique for analyzing Lolspeak utterances within the context of their images based on Grounded Theory (Glaser and Strauss “The Discovery of Grounded Theory” 2007:9). I …

Soft Sediment Relay Zones: A High Resolution Seismic Survey Livingston Parish, Louisiana, Erin T. Elliott Jan 2011

Soft Sediment Relay Zones: A High Resolution Seismic Survey Livingston Parish, Louisiana, Erin T. Elliott

LSU Master's Theses

The southern coast of the United States, bordering the Gulf of Mexico, is home to several down-to-the-south, listric, normal fault systems striking parallel to the coast. One of these, the Baton Rouge–Tepetate Fault System located in southern Louisiana, consists of a series of near-surface, reactivated growth faults and relay ramps– a broad area of ductile strain, with contemporaneous sedimentation. Evidence of recent fault and relay ramp movement is seen in surficial fault line scarps and offset roads. This thesis utilizes two near-surface (<500 >m), high-resolution (10 - 300 Hz), continuous seismic reflection profiles (360 m and 480 m long, 3 …

From Global To Polycentric Climate Governance, Daniel H. Cole Jan 2011

From Global To Polycentric Climate Governance, Daniel H. Cole

Articles by Maurer Faculty

Global governance institutions for climate change, such as those established by the United Nations Framework Convention on Climate Change and the Kyoto Protocol, have so far failed to make a significant impact on greenhouse gas emissions. Following the lead of Elinor Ostrom, this paper offers an alternative theoretical framework for reconstructing global climate policy in accordance with the polycentric approach to governance pioneered in the early 1960s by Vincent Ostrom, Charles Tiebout, and Robert Warren. Instead of a thoroughly top-down global regime, in which lower levels of government simply carry out the mandates of international negotiators, a polycentric approach provides …

The Contribution Of Implicit Stereotypes To The Overrepresentation Of African Americans In The Special Education Category Of Emotional Disturbance, Tai A. Collins Jan 2011

The Contribution Of Implicit Stereotypes To The Overrepresentation Of African Americans In The Special Education Category Of Emotional Disturbance, Tai A. Collins

LSU Master's Theses

The overrepresentation of African Americans in special education is a problem that has plagued the field since its inception, yet very little progress has been made in alleviating the issue. The problem is especially troubling because of the host of negative outcomes associated with special education in general, as well as placing African American students into special education specifically. The current study sought to examine the contribution of implicit racial stereotypes to the overrepresentation problem. Participants were randomly assigned to conditions where they viewed vignettes about either an African American or Caucasian problem student, after which they completed a questionnaire …

The Story Of Kleppe V. New Mexico: The Sagebrush Rebellion As Un-Cooperative Federalism, Robert L. Fischman, Jeremiah Williamson Jan 2011

The Story Of Kleppe V. New Mexico: The Sagebrush Rebellion As Un-Cooperative Federalism, Robert L. Fischman, Jeremiah Williamson

Articles by Maurer Faculty

The story of Kleppe v. New Mexico dramatizes how assertion of federal power advancing national conservation objectives collided with traditional, local economic interests on public lands in the 1970s. This article connects that history with current approaches to natural resources federalism. New Mexico challenged the Wild Free-Roaming Horses and Burros Act, which diminished both state jurisdiction and rancher influence over public rangelands. In response, the Supreme Court resoundingly approved federal authority to reprioritize uses of the public resources, including wildlife, and spurred a lasting backlash in the West. Further legislation passed in the wake of Kleppe transformed this unrest into …

An Euler Solver For Nonlinear Water Waves Using A Modified Staggered Grid And Gaussian Quadrature Approach, Qi Fan Jan 2011

An Euler Solver For Nonlinear Water Waves Using A Modified Staggered Grid And Gaussian Quadrature Approach, Qi Fan

LSU Master's Theses

A structured, finite-volume Euler solver for non-hydrostatic, free surface flows is developed to simulate coastal nonlinear dispersive water waves. A semi-implicit projection method which splits the pressure term into hydrostatic and non-hydrostatic parts is employed. A vertically shifted, staggered grid is designed to accommodate a new Gaussian discharge calculator and to facilitate the enforcement of a non-hydrostatic free-surface boundary condition. The Gaussian discharge calculator on the shifted grid increases the dispersion accuracy compared to traditional approaches that calculate discharges on a regular staggered grid. Numerical results are presented to demonstrate the improvements of these methods.
