Preparation Of High Entropy Titanite Pyrochlore And Radiation Stability Study, Adam Gootgeld

All Theses

Pyrochlore has been studied as a host phase for safe storage of radionuclides and exists naturally with long-term stability with good long-range order [1]. High entropy oxides show promising tunable properties that could demonstrate favorable bulk deposit of radioactive materials such as spent nuclear fuel (Uranium and other actinides). It is proposed that using high entropy oxides (HEOs) as the cation in this framework will shift the gibbs free energy so that radioactive nuclear waste will be stabilized for safe, long-term, eco-friendly storage. We have established a consistent method to fabricate high entropy titanite pyrochlores. In this study, ion beam …

Digital twins (DTs), or virtual replicas of the system and its assets, enhanced with AI paradigms can add enormous value to tasks performed by regulators, distribution system operators and energy market analysts, thereby providing cognition to the system. DTs …

Adaptive Protection Scheme For Microgrids With Seamless Transition, Jason Sabet

All Theses

As traditional, carbon-emitting power generation facilities are being retired, the future of the electric grid is being powered by renewable energy sources and supported by energy storage. Unlike centralized power generation, renewable energy can be installed in a distributed or local manner, leading to a restructuring of the distribution system towards a more modular design and the growth of microgrid technology.

Microgrids are small, locally fed power systems that supply electricity to a specific customer base. Utilities are using this technology to enhance the reliability and resilience of their distribution systems. These utility microgrids can provide grid support during normal …

Tunable Linewidth Chip-Level Lasers Using Hybrid Integration Methods, Charles Porter

All Theses

Photonic integrated circuits (PICs) have significant value in today’s world of research. They enable devices to experience large reductions in size, weight, operation power, and cost (SWAPc), making photonic technology more accessible than ever. The functionality of PICs is greatly enhanced due to the realization of both active and passive devices within a single device structure. This is made possible through hybrid integration, which utilizes various coupling methods to transfer light from an active chip to a passive chip. Hybrid integration technology tremendously expands the capabilities of PICs, leading to a plethora of applications. One significant application is that of …

Augmented Human Inspired Phase Variable Using A Canonical Dynamical System, Timothy Driscoll

All Theses

Accurately parameterizing human gait is highly important in the continued development of assistive robotics, including but not limited to lower limb prostheses and exoskeletons. Previous studies introduce the idea of time-invariant real-time gait parameterization via human-inspired phase variables. The phase represents the location or percent of the gait cycle the user has progressed through. This thesis proposes an alternative approach for determining the gait phase leveraging previous methods and a canonical dynamical system.

Human subject experiments demonstrate the ability to accurately produce a phase variable corresponding to the human gait progression for various walking configurations. Configurations include changes in incline …

Survey And Prevalence Of Palmer Amaranth Herbicide Resistance In South Carolina, Mitchell Williams

All Theses

Palmer amaranth is a troublesome weed for growers to control, not only due to its aggressive growth characteristics that limit row-crop production, but because of its resistance to different herbicide modes of action. The first case of herbicide resistance in Palmer amaranth was detected in 1989 and has since grown to nine different herbicide classes throughout the United States. New herbicide modes of action have not been developed since the 1980s, so proper stewardship of the remaining modes of action is important for effective control of Palmer amaranth. Increased herbicide resistance from states bordering South Carolina have been reported; therefore, …

Experimental Investigation Of The Long-Term Bending Deflection And Creep Performance Of Cross-Laminated Timber (Clt), Aaron Desantis

All Theses

Rising popularity in mass timber construction for residential and commercial projects has escalated the need to develop and increase understanding of mass timber products both from a strength and serviceability perspective. For cross-laminated timber (CLT) there is a significant lack of research on the creep characteristics also known as long-term deflection behavior. Creep is particularly important for products such as CLT that are used for floors with longer spans. Full-scale creep testing was conducted using 5-ply CLT panels over the course of 6 months in a controlled environment under dry service condition. Testing resulted in average final deflections 1.73 times …

Making Summer Camp Inclusive: Staff Perspectives From Two National Youth-Serving Organizations, Bryn Spielvogel, Meagan Ricks, Michael Froehly, Jim Sibthorp, Tellisia Williams, Wendy Friedman, Tara Hetz

Journal of Youth Development

Organized out-of-school time (OST) activities can provide youth with developmentally enriching experiences. Summer camp is one such activity, offering opportunities for positive youth development and, in some cases, promoting socioemotional learning, character development, resilience, and academic and career-related outcomes (Garst et al., 2011; Henderson et al., 2007; Merryman et al., 2012; Whittington & Garst, 2018; Wilson & Sibthorp, 2018). Not all youth, however, have access to high-quality summer programs (Browne et al., 2019; National Academies of Science, Engineering, & Medicine, 2019). Furthermore, summer camps designed around the needs and interests of relatively privileged youth can create exclusive dynamics within camp …

Medical Specialty Camp Alumni Perceptions Of Outcomes And Experiences, Ann Gillard, Allison B. Dymnicki, Leah Brown

Journal of Youth Development

Summertime can be an important time of year for youth development. During summer, children and youth can experience belonging, develop meaningful relationships, and engage in interest-driven learning (NASEM, 2019). For example, Richmond et al. (2019) found that camp, home, work, school, sports, and church contributed to important and useful skills and traits for youth. Specifically, they found that camp was a primary learning setting for developing affinity for nature, how to live with peers, leisure skills, a willingness to try new things, independence, being present, and empathy and compassion whereas school and home were primary learning settings for other outcomes …

Design Of Bamboo Reinforced Concrete Beams Considering Variability In Tensile Strength Of Bamboo, Bibek Bhardwaj, Michael Stoner, Weichiang Pang

Publications

In recent years, the price of steel has soared, making steel reinforcement in concrete structures unaffordable for households in low-income countries. Seismic activities in low-income households, particularly those in developing countries, pose a significant threat to life and property to unreinforced concrete structures. The application of bamboo as an alternative to steel in reinforced concrete is still in its early stages of development. Unlike steel, bamboo is a natural material, and its structural properties vary greatly based on species, location, age, and geometric properties. Thus, the design of bamboo-reinforced concrete involves more uncertainties than steel-reinforced concrete. This research investigates the …

Publications

Artificial intelligence (AI) is used in the clinic to improve patient care. While the successes illustrate the impact AI can have, few studies have led to improved clinical outcomes. A gap in translational studies, beginning at the basic science level, exists. In this review, we focus on how AI models implemented in non-orthopedic fields of corrosion science may apply to the study of orthopedic alloys. We first define and introduce fundamental AI concepts and models, as well as physiologically relevant corrosion damage modes. We then systematically review the corrosion/AI literature. Finally, we identify several AI models that may be Preprint …

An Introduction To Consumptive Use Of Water In South Carolina, Heather Bergerud Nix, Mani Rouhi Rad

Journal of South Carolina Water Resources

Effective water resource management requires understanding the supply of and the demand for water. In South Carolina, as in other places, water demand is often determined using total withdrawal volumes. However, the volume of water that is withdrawn can be significantly different from the volume that is actually consumed, which becomes unavailable for downstream uses. Water used for energy generation is commonly excluded from evaluations of total withdrawal volume because it is often assumed to be no or low consumptive use, meaning much of the withdrawn water is returned to the source and remains available for downstream uses. Additionally, energy …

Chlorophyll A Predictions In A Piedmont Lake In Upstate South Carolina Using Machine-Learning Approaches, Ibrahim O. Busari, Debabrata Sahoo, Raghavendra Jana, Charles Privette

Journal of South Carolina Water Resources

Freshwater systems are often breeding grounds for harmful algal blooms (HABs), although they are more dominant in ponds and lakes due to the prevailing conditions in those bodies of water. Therefore, the monitoring, modeling, and management of HABs requires knowledge of the complex interrelationship between factors that influence HABs and their detrimental effect on the ecosystem. High concentrations of chlorophyll a are often used to measure algal blooms in bodies of water. Generally, water samples are collected from the field and the concentration of chlorophyll a is measured in a laboratory and compared to water quality standards in order to …

Thermoplastics Foams: An Automotive Perspective, Sai Aditya Pradeep, Srishti Shukla, Nathaniel Brown, Srikanth Pilla

Publications

The automotive industry has witnessed a massive shift in terms of materials used, ranging from being a metallic heavyweight in the 1950s to employing a hybrid sandwich of multiple material systems. This apparent shift can be attributed to achieving improvements in performance, safety and fuel efficiency, along with responding to the various environmental regulations imposed by different governments. The recent advocacy of Corporate Average Fuel Economy (CAFE) standard of 54.5 MPG by 2025 by the US Environmental Protection Agency (EPA) to reduce greenhouse gas (GHG) emissions [1] has spurred the sector at large towards the use of lightweight materials.

Composites 4.0: Enabling The Modernization Of Legacy Manufacturing Assets In South Carolina, Amit Makarand Deshpande, Gayatri Keskar, Sai Aditya Pradeep, Saeed Farahani, Srikanth Pilla

Publications

Composites 4.0 is the implementation of Industry 4.0 concepts to plastics and composites manufacturing with the goal to overcome the complexities associated with these materials. Due to very complex process-structure-property relationships associated with plastics and composites, a wide range of process parameters need to be tracked and monitored. Furthermore, these parameters are often affected by the tool and machinery, human intervention and variability and should thus, be monitored by integrating intelligence and connectivity in manufacturing systems. Retrofitting legacy manufacturing systems with modern sensing and control systems is emerging as one of the more cost-effective approaches as it circumvents the substantial …

Patent searching is an important research tool for undergraduate engineering students, yet it requires special topic knowledge to conduct successfully. Patent database websites have the ability to alleviate or add to the complexity of patent searching, depending on their usability. Prompted by the launch of the US Patent and Trademark Office’s Patent Public Search (PPS) website in early 2022, the authors investigated the usability of PPS and Google Patents. The study's objective was to gain insights into the ways in which the websites of commonly-used patent databases support undergraduate students’ patent searching activities. The study examined students’ performance of typical …

A Case Study Of The Complicated History Of Rice University’S First Patents, Hannah G. Edlund

Journal of the Patent and Trademark Resource Center Association

Digitization and online public databases have made patent searches a much simpler pursuit in recent years. However, uncovering a pre-digital era patent’s history and context remains challenging. A search for the first patents assigned to Rice University highlighted associated issues. Older patent formats often do not clearly indicate inventor-assignee relationships, and applications and official communications are not available online. To determine how Rice came to own three 1948 patents, extensive archival research was required. Were these patents assigned to the University by inventors, independent of its support or funding, or was their work performed at and for Rice, thus obliging …

Journal of South Carolina Water Resources

The South Carolina Department of Health and Environmental Control has recently incentivized planners to incorporate climate change projections into watershed-based plans. Methods for doing so vary by geography, specific basin-level conditions, and available resources. This short communication documents an early example developed by a collaborative team including a council of governments, private contractor, and university researchers. We outline steps taken to construct climate change scenarios, incorporate them into a basin-level model, and develop a holistic approach to climate adaptation and resilience for the Three Rivers Watershed-Based Plan in the Columbia, South Carolina, metropolitan area. We present lessons learned about integrating …

Mapping And Characterization Of Center Pivot And Lateral Move Irrigation Systems In South Carolina Using Quantum Geographic Information System, Udayakumar Sekaran, José O. Payero

Journal of South Carolina Water Resources

In recent decades, the adoption of overhead irrigation systems, especially center pivots, to irrigate row crops has been steadily increasing in South Carolina. The adoption of irrigation in the state has been enhanced by the predominance of coarse-textured soils with low water-holding capacities, which increases the likelihood of obtaining a significant and profitable crop yield response to irrigation. As the number of overhead irrigation systems in the state increases, it is vital to understand their number, location, and characteristics for better planning and managing available water resources. The objective of this project was to map and characterize the overhead irrigation …
