Emergence Of Delamination Fractures Around Casing And Its Stability, Wei Wang Jan 2013

Emergence Of Delamination Fractures Around Casing And Its Stability, Wei Wang

LSU Doctoral Dissertations

The cement sheath failures and nearby wellbore failures may lead to upward flow of drilling fluid or formation fluid, which may have significantly adverse consequences like loss of reserve and environmental hazards. In order to maintain wellbore integrity in the long term, it is expedient to examine the causes of failures around the wellbore and propose suitable numerical models to predict annulus cracks around the casing. The complex failure behavior of cement/rock interfaces observed in the laboratory experiments does not look like the behavior of linear or simple nonlinear mechanical interfaces. Cohesive zone method (CZM) with BK-form bilinear traction separation …

Quantum Simulations On Square And Triangular Hubbard Models, Kuang-Shing Chen Jan 2013

Quantum Simulations On Square And Triangular Hubbard Models, Kuang-Shing Chen

LSU Doctoral Dissertations

In this thesis we try to understand the unconventional superconducting mechanism on cuprates and organic superconductors (or sodium cobaltates) which can be modeled by a two-dimensional square- and triangular-lattice Hubbard model respectively. The formation of the superconducting dome requires explanations of feasible scenarios. Generally speaking, pairing strength is provided by magnetic fl_x001D_uctuations in the strongly correlated region and the structure of the Fermi surface in this region will favor superconducting pairings with a certain type of symmetry. For the cuprate physics, a superconducting dome composed of d-wave pairings has been identified experimentally. We study the Hubbard model on square lattices …

Ecosystem Metabolism In Coastal Plain Streams Of Southeast Louisiana : Environmental And Watershed Effects, Jonathan L. West Jan 2013

Ecosystem Metabolism In Coastal Plain Streams Of Southeast Louisiana : Environmental And Watershed Effects, Jonathan L. West

LSU Doctoral Dissertations

Since its introduction in 1956, the use of open-system, diel dissolved oxygen curves for estimating the components of ecosystem metabolism in the lotic setting have been important in determining the current ecosystem theory of streams, both spatially among multiple systems and longitudinally within the same system, as well as identifying potentially impaired systems, especially when contrasted with streams considered unimpaired. Several factors have been identified as controls on both components of ecosystem metabolism and include light, nutrients, and stable substrates for gross primary production (GPP) and a source of organic matter (OM) for ecosystem respiration (ER). Stream size is important …

The Polysemy Of Privacy, Ronald J. Krotoszynski Jr. Jan 2013

The Polysemy Of Privacy, Ronald J. Krotoszynski Jr.

Articles

"The Polysemy of Privacy" considers the highly protean nature of the concept of "privacy" which extends to myriad disparate legal interests including nondisclosure generalized autonomy interests and even human dignity For a concept of such central importance to many systems of protecting fundamental rights its precise contours are surprisingly illdefined This lack of determinate meaning is not limited to the concept of "privacy" in the United States virtually all legal systems that utilize "privacy" or its first cousin "dignity" have experienced difficulty reducing the concept into specific carefully delineated legal interests In some respects privacy means everything "“ and nothing …

Reef Fish Demographics On Louisiana Artificial Reefs : The Effects Of Reef Size On Biomass Distribution And Foraging Dynamics, Kirsten A. Simonsen Jan 2013

Reef Fish Demographics On Louisiana Artificial Reefs : The Effects Of Reef Size On Biomass Distribution And Foraging Dynamics, Kirsten A. Simonsen

LSU Doctoral Dissertations

Understanding the role that habitat plays in the life history of reef-associated fishes is particularly significant given the dramatic increase in the number of artificial reefs deployed in coastal ecosystems over the past 50 years. In the Gulf of Mexico, the oil and gas industry has added a significant amount of structure to the Louisiana continental shelf, creating the largest de facto artificial reef deployment area in the world. Noting their usefulness as fish habitat, the Louisiana Artificial Reef Program was established to convert decommissioned platforms into artificial reefs. However, very little quantitative information exists on how these habitats affect …

Complexity In Property, Meredith M. Render Jan 2013

Complexity In Property, Meredith M. Render

Articles

This article illuminates the largely misunderstood relationship between complexity and the regulation of property interests Specifically the article presents the complexity thesis a novel explanatory account of the principle of numerus clausus The principle of numerus clausus is an ancient common law rule which prohibits the customization of property interests The complexity thesis holds that the primary function of numerus clausus is to prevent the proliferation of highly idiosyncratic property interests In so doing numerus clausus provides a bulkhead against the overwhelming complexity that would ensue if customized property interests were permitted For the last fifteen years numerus clausus has …

Silica Polypeptide-Based Colloids: Physical Properties And Novel Materials, Cornelia Rosu Jan 2013

Silica Polypeptide-Based Colloids: Physical Properties And Novel Materials, Cornelia Rosu

LSU Doctoral Dissertations

The investigation of polypeptide composite particles, PCPs, is described. The production of mesoporous and polycolloid architectures is also addressed. PCPs were prepared by both growing form and grafting to method. They consist of a core made of silica, silica-coated magnetite or silica-coated cobalt. Some of the particles were covalently labeled with fluorescein isothiocyanate. Several polypeptides were chosen for attachment on the core: poly(γ-stearyl-L-glutamate), PSLG, poly(Nε-carbobenzyloxy-L-lysine), PCBL and poly(o-benzyl-L-tyrosine), PBTY. Attachment of a well-characterized alkyne-end terminated PSLG and PCBL to an azide- functionalized particle yielded PCPs with a desired sparse coverage. A blend of techniques such as FTIR, XPS, TEM, HTEM, …

Treatment Integrity Failures Matched To Behavioral Function, Joanna Elizabeth Lomas Mevers Jan 2013

Treatment Integrity Failures Matched To Behavioral Function, Joanna Elizabeth Lomas Mevers

LSU Doctoral Dissertations

Prior research on treatment integrity has focused on either the lack of measurement of the independent variable (Peterson, Homer & Wonderlich, 1982; Gresham, Gansle & Noel, 1993; Wheeler, Baggett, Fox & Blevins, 2006; McIntyre, Gresham, DiGennaro & Reed, 2007; Sanetti, Gritter & Dobey, 2011) or on methods to increase overall levels of treatment integrity(Witt, Noell, LaFleur & Mortenson, 1997; Noell, Witt, Gilbertson, Ranier & Freeland,1997; Noell et al., 2005). Yet little research has been devoted to understanding the effectiveness of common interventions when those interventions are implemented with less than perfect integrity. The current investigation evaluated the effectiveness of using …

A Large Scale Network Model To Obtain Interwell Formation Characteristics, Seyedmohammadamin Gherabati Jan 2013

A Large Scale Network Model To Obtain Interwell Formation Characteristics, Seyedmohammadamin Gherabati

LSU Doctoral Dissertations

Limited data availability and poor data quality make it difficult to characterize many reservoirs. For reservoirs that have undergone waterflooding, production and injection data are a reliable source of information from which injector-to-producer connections can be inferred. In this research, we use well locations, injection and production rate data and well fractional flow values to develop a reservoir-scale network model. A Voronoi mesh divides the reservoir into a number of node volumes each of which contains a well. Bonds connect each of the nodes with conductance values that must be inferred from the rate data. An inverse problem is formulated …

Molecular-Level Investigations Combining Nanoscale Lithography And Atomic Force Microscopy, Chamarra Karmelia Saner Jan 2013

Molecular-Level Investigations Combining Nanoscale Lithography And Atomic Force Microscopy, Chamarra Karmelia Saner

LSU Doctoral Dissertations

In this dissertation, nanostructures of octadecyltrichlorosilane (OTS) and were prepared using particle lithography and evaluated using characterizations with atomic force microscopy (AFM). The nanostructures of OTS were used as a resist for patterning fibronectin, an extracellular matrix protein. Particle lithography provides a practical and reproducible approach to generate billions of nanostructures comprised of organic thin films or nanomaterials. A film of mesospheres can be applied as a surface mask to define the periodicity and size of nanopatterns using processes of self-assembly. A close-packed arrangement of mesospheres is produced spontaneously when monodisperse solutions of latex or silica are dried on a …

Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins Jan 2013

Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins

LSU Doctoral Dissertations

Two studies investigated the effectiveness of the Reciprocal Peer Mentoring intervention in improving the prosocial behavior of socially neglected elementary school students as measured by a Direct Behavior Rating filled out by their teachers. Reciprocal Peer Mentoring uses the methodological framework of the Check-In/Check-Out intervention (e.g. Hawken & Horner, 2003), but expands on it by using peers as mentors, adding a reciprocity component, focusing on prosocial behavior, and targeting socially neglected students. In Study 1, the effectiveness of Nonreciprocal Peer Mentoring was examined, as popular peers served as mentors for neglected peers. In Study 2, neglected or rejected students mentored …

The Role Of Self And Parental Criticism In Non-Suicidal Self-Injury, Brooke Aleece Ammerman Jan 2013

The Role Of Self And Parental Criticism In Non-Suicidal Self-Injury, Brooke Aleece Ammerman

Dissertations and Theses @ UNI

Non-suicidal self-injury (NSSI) is found at high rates among adolescents and young adults, and often produces many negative consequences, warranting additional research (Yates, 2004). Parental criticism and self-criticism may greatly influence the likelihood of NSSI in these populations (Wedig & Nock, 2007), but the relationship needs to be expanded upon. The purpose of the current study was to address this need by measuring self-criticism, perceived parental criticism, and parent-reported criticism among adolescents and young adults. Results suggest that levels of self-criticism and perceived expressed emotion may influence whether or not an individual engages in NSSI. One particular aspect of self-criticism, …

Pulsed Line Source Response Of A Thin Sheet With High-Contrast Dielectric And Conductive Properties - A Time-Domain Analysis, Adrianus T. De Hoop, Ling Ling Meng, Li (Lijun) Jun Jiang Jan 2013

Pulsed Line Source Response Of A Thin Sheet With High-Contrast Dielectric And Conductive Properties - A Time-Domain Analysis, Adrianus T. De Hoop, Ling Ling Meng, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

A methodology is presented for analytically modeling the reflection and transmission of line-source excited pulsed electromagnetic fields at a thin, planar layer with high-contrast dielectric and conductive properties. Closed-form analytic time-domain expressions are derived for the field components in a 2-D setting via an extension of the Cagniard-DeHoop method. The response to the power exponential source and the power exponential monocycle pulse were studied using the newly proposed method. © 2013 IEEE.

Skin-Effect Loss Models For Time- And Frequency-Domain Peec Solver, Albert E. Ruehli, Giulio Antonini, Li (Lijun) Jun Jiang Jan 2013

Skin-Effect Loss Models For Time- And Frequency-Domain Peec Solver, Albert E. Ruehli, Giulio Antonini, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

A challenging and interesting issue for the solution of large electromagnetic problems is the efficient, sufficiently accurate modeling of the broadband skin-effect loss for conducting planes and 3-D shapes. The inclusion of such models in an electromagnetic (EM) solver can be very costly in compute time and memory requirements. These issues are particularly important for the class of signal, power, and noise integrity (NI) problems. In this paper, we concentrate on partial element equivalent circuit (PEEC)-type methods which are suitable for the solution of this class of problems. Progress has been made recently in the design of skin-effect models. The …

Finite-Width Feed And Load Models, Yat Hei Lo, Li (Lijun) Jun Jiang, Weng Cho Chew Jan 2013

Finite-Width Feed And Load Models, Yat Hei Lo, Li (Lijun) Jun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

We demonstrate a new method of applying the feed model for the method of moments (MoM) formulation for the electric field integral equation (EFIE). The model is based around a previously reported magnetic ribbon current model which is accurate and allows for a finite width of the feed port. However, with proper approximations, one can reduce the formulation such that the magnetic field operator can be removed in order to simplify computations arising from the curl of the dyadic Green's function and its singularities. We show here that the new feed model can also be used to model a lumped …

An Iterative Source Reconstruction Method Exploiting Phaseless Electric Field Data, Ping Li, Lijun Jiang Jan 2013

An Iterative Source Reconstruction Method Exploiting Phaseless Electric Field Data, Ping Li, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Conventional equivalent source reconstruction methods (SRM) require both phase and amplitude information of the acquired field data. However, there are situations where the phase information is not available or impractical to obtain. Hence, the development of SRM using phaseless fields is important. In this paper, a novel iterative SRM based on phaseless electric fields is presented. The reconstructed equivalent current source can be electric, magnetic current, or both. They can fit the physical geometry of the radiator. Electric field integral equation (EFIE) is employed to build the relationship between the reconstructed current source and measured fields. It can precisely reproduce …

Asking The First Question: Reframing Bivens After Minneci, Alexander A. Reinert, Lumen N. Mulligan Jan 2013

Asking The First Question: Reframing Bivens After Minneci, Alexander A. Reinert, Lumen N. Mulligan

Articles

In Minneci v. Pollard, decided in January 2012, the Supreme Court refused to recognize a Bivens v. Six Unknown Federal Narcotics Agents suit against employees of a privately run federal prison because state tort law provided an alternative remedy, thereby adding a federalism twist to what had been strictly a separation-of-powers debate. In this Article, we show why this new state-law focus is misguided. We first trace the Court’s prior alternative-remedies-to-Bivens holdings, illustrating that this history is one narrowly focused on separation of powers at the federal level. Minneci’s break with this tradition raises several concerns. On a …

Postmodern Humanism And The "Exhaustion Of Easy Life", Mason Beets Jan 2013

Postmodern Humanism And The "Exhaustion Of Easy Life", Mason Beets

Dissertations and Theses @ UNI

The twenty-first century appears to herald a new epoch, one in which religion and other similar belief systems appear to have run their course. However, this should not necessarily mean that other forms of spirituality and interconnectedness must fade away. Within America, there is a humanistic undercurrent that is gaining strength within our postmodern condition, even as we begin to challenge several of the tenets of postmodernity itself. The groundswell of American humanism has a notable and wholly unintended effect: it ideologically rehabilitates modes or vehicles of thought that might otherwise be labeled as defunct, or inapplicable to the changing …
