Effects Of Fabrication Errors On The Focusing Performance Of A Sector Metalens, S. S. Stafeev, A. G. Nalimov, Liam O’Faolain, M. V. Kotlyar

Cappa Publications

Using e-beam lithography, a 16-sector spiral metalens was fabricated in an amorphous silicon, capable of converting linearly polarized incident light into an azimuthally polarized optical vortex. When illuminated by a 633-nm linearly polarized laser beam, the metalens generated a near-surface subwavelength focal spot equal to 0.75 of the incident wavelength at full-width of half-maximum intensity. The focusing performance of the spiral metalens was numerically shown to be sensitive to the deviation of the factual microrelief from the calculated height. For the designed microrelief height, a circularly polarized incident beam was focused into a bright ring with a reverse energy flow …

Using Carbon Isotope Fractionation To Constrain The Extent Of Methane Dissolution Into The Water Column Surrounding A Natural Hydrocarbon Gas Seep In The Northern Gulf Of Mexico, M. Leonte, B. Wang, Scott A. Socolofsky, John A. Breier, John D. Kessler

School of Earth, Environmental, & Marine Sciences Faculty Publications

A gas bubble seep located in the northern Gulf of Mexico was investigated over several days to determine whether changes in the stable carbon isotopic ratio of methane can be used as a tracer for methane dissolution through the water column. Gas bubble and water samples were collected at the seafloor and throughout the water column for isotopic ratio analysis of methane. Our results show that changes in methane isotopic ratios are consistent with laboratory experiments that measured the isotopic fractionation from methane dissolution. A Rayleigh isotope model was applied to the isotope data to determine the fraction of methane …

Active Disturbance Rejection Control Of Lcl-Filtered Grid-Connected Inverter Using Pade Approximation, Abdeldjabar Benrabah, Dianguo Xu, Zhiqiang Gao

Electrical and Computer Engineering Faculty Publications

In this paper, a simplified robust control is proposed to improve the performance of a three-phase current controlled voltage source inverter connected to the grid through an inductive-capacitive-inductive ( LCL) filter. The presence of the LCL-filter resonance complicates the dynamics of the control system and limits its overall performance, particularly when disturbances and parametric uncertainty are considered. To solve this problem, a robust active damping method based on the linear active disturbance rejection control (LADRC) is proposed. The simplification is made possible by order reduction in the plant transfer function using Padé approximation. Simulation results show that the proposed LADRC-based …

Christian High School Science Teachers' Perspective Transformation: The Journey From Evolution To Creation, Paul Leslie Thorpe

Doctoral Dissertations and Projects

The purpose of this hermeneutical phenomenology study was to explore and describe the perspective transformations of 11 science instructors teaching at Christian high schools. These science teachers previously believed the evolutionary paradigm of origins. However, they have all experienced a transformation and now hold a young-earth creation perspective and believe the literal six-day creation event in the book of Genesis is accurate and true. Transformation of perspective regarding origins is defined as a phenomenon of transformative faith accompanied by assimilation and accommodation of new knowledge as seen through the lens of Jack Mezirow’s (1991) transformative adult learning theory, and James …

Addressing Environmental Gentrification: Improving Environmental Health For Children And Youth Without Displacement, Tania Schusler, Amy Krings

Center for the Human Rights of Children

This research brief aims to consider how community members and policies might improve environmental amenities within contaminated communities without displacing existing residents. To this end, we will first introduce a concept known as environmental gentrification. We will then summarize some of the existing literature that explores the relationships between urban greening and brownfield redevelopment projects in relation to gentrification. Brownfields refer to properties where the presence or potential presence of a hazardous substance, pollutant, or contaminant may complicate the property’s expansion, redevelopment, or reuse (https://www.epa.gov/brownfields/overview-brownfields- program). Our review of literature indicates that the degree of gentrification associated with sustainable development …

Field Oriented Sliding Mode Control Of Surface-Mounted Permanent Magnet Ac Motors: Theory And Applications To Electrified Vehicles, Xin Wang, Max Reitz, Edwin E. Yaz

Electrical and Computer Engineering Faculty Research and Publications

Permanent magnet ac motors have been extensively utilized for adjustable-speed traction motor drives, due to their inherent advantages including higher power density, superior efficiency and reliability, more precise and rapid torque control, larger power factor, longer bearing, and insulation life-time. Without any proportional-and-integral (PI) controllers, this paper introduces novel first- and higher-order field-oriented sliding mode control schemes. Compared with the traditional PI-based vector control techniques, it is shown that the proposed field oriented sliding mode control methods improve the dynamic torque and speed response, and enhance the robustness to parameter variations, modeling uncertainties, and external load perturbations. While both first- …

Molecular Level Interactions And Transformations Of Natural Organic Matter Within The Environment, Benjamin J. Haywood

LSU Doctoral Dissertations

This work was done in order to deepen the understanding of interactions occurring during sorption of anthropogenic organic compounds and dissolved organic matter (DOM) onto soil. As well as the transformation DOM undergoes during the sorption process and the overall transformation OM undergoes in the environment. This was achieved through the use of a “bottom-up” synthetic investigation, “top-down” natural system study, and a combination of these approaches.

The “bottom-up” approach, discussed in Chapter 2, involved the synthesis of a modular multi-tiered engineered soil surrogate (ESS) designed to mimic OM and general trends identified in the literature that impacts sorption behavior. …

Development Of Hydroxyapatite-Polymer Sorbents For The Removal Of Heavy Metal Ions From Waste Waters, Eleanora Charnetskaya

Chemistry Theses

Water pollution due to the presence of soluble metal ions is one of the greatest challenges to environmental scientists. Different methods have been explored to the removal of these soluble ions. Among these methods, elimination by sorption into/onto solid materials has been considered one of the successful approaches. Sorbent materials usually chemically interact with soluble ions and eliminate them by bond formation between the ions and the sorbent molecules. On the other hand, soluble ions can be also exchanged with inorganic sorbents in which other environmentally friendly ions can exchange with the soluble metal ions. In the current study, the …

Piezoelectric-Based Cardiac Monitoring Portable System, Shina Siamak Mokhtari

Electrical Engineering Theses

In this thesis, a portable-based cardiac monitoring system is discussed, which helps to keep a check on the corresponding patient vitals.
