The Socialization Of Students Serving On United States Public Post-Secondary Education Boards, Erin Renee Bendily

LSU Doctoral Dissertations

This study aimed to explain how student members of United States public post-secondary education boards are socialized into their roles and how specific strategies influence their engagement and effectiveness. Researchers have studied student involvement and leadership, including why and how students become involved, individual and institutional benefits, challenges that students experience, and perceptions about students’ involvement in decision-making. Literature also addresses organizational socialization and that of post-secondary education board newcomers, including strategies that organizations use to support their engagement and effectiveness. Little research, however, has been done on the ways in which those boards attempt to support and facilitate students’ …

Non-Parametric Classification Of Time Series Using Permutation Ordinal Statistics, Aldo Duarte Vera Tudela

LSU Master's Theses

The present thesis explores some approaches to classify time series without prior statistical information using the concept of permutation entropy. Motivated by the results from a previous published and relevant work that set similarity relationships between EEG time series, a reproduction of the proposed approach was performed giving negative results. The failure to reproduce those results led to the conclusion that the approach of building statistics from permutation patterns have to be complemented with another metric in order to be used for classification purposes. The concept of Total Variation Distance (TVD) was then used to develop three algorithms to classify …

Taking (Birth) Control: Empowerment Through Contraceptive Education, Meghan Saas

LSU Master's Theses

TAKING (birth) CONTROL is a body of work that educates women on their options for contraceptives, and empowers them to claim their right to choose if—and when—to have a child. Utilizing graphic design and letterpress printing processes, I created a visual system consisting of carefully honed typographic, color, and graphic styles. The bulk of the materials make up an educational toolkit for use at Delta Clinic of Baton Rouge, one of only three remaining abortion providers in Louisiana. Delta Clinic was in need of comprehensive and affordable materials for their patients on the subject of contraception. The toolkit consists of …

Selected participants were interviewed to gather data from their own narratives about the experiences and challenges as current women Deans in higher education. Each participant attributed their success to family support and proper mentoring, while highlighting institutional policies acting as a form of gendered oppression. Recommendations were suggested to higher educational representatives and legislators concerning the correction of the gendered environment favoring the advancement of men into a more equitable …

Thermal And Mechanical Energy Harvesting Using Lead Sulfide Colloidal Quantum Dots, Taher Ghomian

LSU Doctoral Dissertations

The human body is an abundant source of energy in the form of heat and mechanical movement. The ability to harvest this energy can be useful for supplying low-consumption wearable and implantable devices. Thermoelectric materials are usually used to harvest human body heat for wearable devices; however, thermoelectric generators require temperature gradient across the device to perform appropriately. Since they need to attach to the heat source to absorb the heat, temperature equalization decreases their efficiencies. Moreover, the electrostatic energy harvester, working based on the variable capacitor structure, is the most compatible candidate for harvesting low-frequency-movement of the human body. …

Evaluation Of Oral Function Before And After Frenectomy In Breastfed Infants Diagnosed With Tethered Oral Tissue, Cindy L. Parr

LSU Doctoral Dissertations

Assessment and treatment of tethered oral tissue, or tongue tie, vary within and across providers, resulting in inconsistent surgical and therapeutic outcomes. Assessment and treatment have historically focused on the anatomical (structural) underpinnings of tongue tie, as opposed to the physiological (functional) aspects that can affect daily activities. This is particularly noteworthy in the infant population in regards to breastfeeding. Clinical findings, however, suggest that connections exist between tongue tie and a variety of other oral functions that go beyond breastfeeding. The goal of this research was to examine a relatively small group of breastfed infants with tethered oral …

Computational Aerodynamics And Anatomical Characterization Of Laryngotracheal Stenosis In Children, William Poynot

LSU Master's Theses

Laryngotracheal stenosis (LTS) is a health condition in which an obstruction in the upper trachea can cause breathing difficulties and increased incidence of infection, among other symptoms. Occurring most commonly due to intubation in infants, LTS often requires corrective surgery. Currently, clinical methods of assessing the blockage region are simplistic and subjective, and it is challenging to determine the most effective surgical strategy for any given patient. In the present work, a comprehensive methodology is proposed for characterizing the stenosis region both in terms of its anatomical parameters and its corresponding aerodynamic properties. The combination of computational fluid dynamics (CFD) …

Partner Gender As A Predictor Of Relationship Satisfaction, Sexual Satisfaction, Relationship Commitment, And Attachment Identity Among Women, Amy Leigh Wright

LSU Doctoral Dissertations

Previous research examining overall relationship satisfaction, relationship commitment, and sexual satisfaction among heterosexual women is well-documented. The theoretical foundation of attachment has also been well-established within relationship research among heterosexual women. However, little to no published reports examine such variables among women currently in same-sex relationships. Furthermore, virtually no reports assess for any differences in attachment identity based on the gender of women’s romantic partners. This study therefore sought to identify any interrelationships between relationship satisfaction, relationship commitment, sexual satisfaction, and attachment identity (measured using the dimensions of avoidance and anxiety) among two groups of women based on their partner’s …

With the Auger Engineering Radio Array (AERA) of the Pierre Auger Observatory, we have observed the radio emission from 561 extensive air showers with zenith angles between 60 and 84. In contrast to air showers with more vertical incidence, these inclined air showers illuminate large ground areas of several km2 with radio signals detectable in the 30 to 80 MHz band. A comparison of the measured radio-signal amplitudes with Monte Carlo simulations of a subset of 50 events for which we reconstruct the energy using the Auger surface detector shows agreement within the uncertainties of the current analysis. As expected …

Machine Learning Tools For Optimization Of Fuel Consumption At Signalized Intersections In Connected/Automated Vehicles Environment, Saleh Ragab Mousa

LSU Doctoral Dissertations

Researchers continue to seek numerous techniques for making the transportation sector more sustainable in terms of fuel consumption and greenhouse gas emissions. Among the most effective techniques is Eco-driving at signalized intersections. Eco-driving is a complex control problem where drivers approaching the intersections are guided, over a period of time, to optimize fuel consumption. Eco-driving control systems reduce fuel consumption by optimizing vehicle trajectories near signalized intersections based on information of the SpaT (Signal Phase and Timing). Developing Eco-driving applications for semi-actuated signals, unlike pre-timed, is more challenging due to variations in cycle length resulting from fluctuations in traffic demand. …

Deconstruction And Conditional Erasure Of Quantum Correlations, Mario Berta, Fernando G.S.L. Brandaõ, Christian Majenz, Mark M. Wilde

Faculty Publications

We define the deconstruction cost of a tripartite quantum state on systems ABE as the minimum rate of noise needed to apply to the AE systems, such that there is negligible disturbance to the marginal state on the BE systems, while the system A of the resulting state is locally recoverable from the E system alone. We refer to such actions as deconstruction operations and protocols implementing them as state deconstruction protocols. State deconstruction generalizes Landauer erasure of a single-party quantum state as well the erasure of correlations of a two-party quantum state. We find that the deconstruction cost of …

On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of this gravitational-wave signal, GW170817, offers a novel opportunity to directly probe the properties of matter at the extreme conditions found in the interior of these stars. The initial, minimal-assumption analysis of the LIGO and Virgo data placed constraints on the tidal effects of the coalescing bodies, which were then translated to constraints on neutron star radii. Here, we expand upon previous analyses by working under the hypothesis that both bodies were …

Economic Approaches And Market Structures For Temporal-Spatial Spectrum Sharing, Feixiang Zhang

LSU Doctoral Dissertations

In wireless communication systems, economic approaches can be applied to spectrum sharing and enhance spectrum utilization.

In this research, we develop a model where geographic information, including licensed areas of primary users (PUs) and locations of secondary users (SUs), plays an important role in the spectrum sharing system. We consider a multi-price policy and the pricing power of noncooperative PUs in multiple geographic areas. Meanwhile, the value assessment of a channel is price-related and the demand from the SUs is price-elastic. By applying an evolutionary procedure, we prove the existence and uniqueness of the optimal payoff for each PU selling …

Bipartite Quantum Interactions: Entangling And Information Processing Abilities, Siddhartha Das

LSU Doctoral Dissertations

The aim of this thesis is to advance the theory behind quantum information processing tasks, by deriving fundamental limits on bipartite quantum interactions and dynamics. A bipartite quantum interaction corresponds to an underlying Hamiltonian that governs the physical transformation of a two-body open quantum system. Under such an interaction, the physical transformation of a bipartite quantum system is considered in the presence of a bath, which may be inaccessible to an observer. The goal is to determine entangling abilities of such arbitrary bipartite quantum interactions. Doing so provides fundamental limitations on information processing tasks, including entanglement distillation and secret key …

Applications Of Position-Based Coding To Classical Communication Over Quantum Channels, Haoyu Qi, Qingle Wang, Mark M. Wilde

Faculty Publications

Recently, a coding technique called position-based coding has been used to establish achievability statements for various kinds of classical communication protocols that use quantum channels. In the present paper, we apply this technique in the entanglement-assisted setting in order to establish lower bounds for error exponents, lower bounds on the second-order coding rate, and one-shot lower bounds. We also demonstrate that position-based coding can be a powerful tool for analyzing other communication settings. In particular, we reduce the quantum simultaneous decoding conjecture for entanglement-assisted or unassisted communication over a quantum multiple access channel to open questions in multiple quantum hypothesis …

Project Narrative: Examining The Interplay Of Experiences Of Participants In An After-School Writing Club, Courtney A. Brown

LSU Doctoral Dissertations

Writing is a vital part of literacy development. It affords the opportunity for the expression and analysis of comprehensive thought, while simultaneously being a modality for unique and creative communication. In order for productive dialogue about the study of writing to be engaged, the contemplation of its many dynamic parts occurring across a diversity of contexts must be considered in such a way that one writing strategy, process, product or environment is not privileged above another. Each constituent part of writing construction contributes meaningfully to the existing body of research for this field, and when carefully disaggregated can offer specific …

Embodiments of the present invention include methods for increasing off-chip bandwidth. The method includes designing a circuit of switchable pins, replacing a portion of allocated pins of a processor with switchable pins, connecting the processor to a memory interface configured to switch the switchable pins between a power mode and a signal mode, providing a metric configured to identify which of the power mode and the signal mode is most beneficial during 1 millisecond intervals, and switching the switchable pins to signal mode during intervals where the signal mode provides more benefit than the power mode.

3d Mri Modeling Of Thin And Spatially Complex Soft Tissue Structures Without Shrinkage: Lamprey Myosepta As An Example, Bradley M. Wood, Guang Jia, Owen Carmichael, Kevin Mcklveen, Dominique G. Homberger

Faculty Publications

© 2018 Wiley Periodicals, Inc. 3D imaging techniques enable the nondestructive analysis and modeling of complex structures. Among these, MRI exhibits good soft tissue contrast, but is currently less commonly used for nonclinical research than X-ray CT, even though the latter requires contrast-staining that shrinks and distorts soft tissues. When the objective is the creation of a realistic and complete 3D model of soft tissue structures, MRI data are more demanding to acquire and visualize and require extensive post-processing because they comprise noncubic voxels with dimensions that represent a trade-off between tissue contrast and image resolution. Therefore, thin soft tissue …
