Hybrid Energy Systems: Synergy Margin And Control Co-Design, Mario Garcia Sanz
Hybrid Energy Systems: Synergy Margin And Control Co-Design, Mario Garcia Sanz
Faculty Scholarship
Extraordinary properties emerge from subsystems' interactions. Hybrid energy systems (HESs) are a promising concept that could change the renewable energy landscape. By co-designing generation, storage, and conversion technologies, HESs can provide new electrical power services, increase grid stability and control authority, and generate energy and/or nonenergy products such as electricity, hydrogen, ammonia, heat, digital data, or fresh water. This article discusses some conditions the co-design of HESs should follow to optimize the combined system (synergy), avoiding deterioration (dysfunction). It introduces some technoeconomic synergy conditions, develops a synergy margin, and analyses several case studies, exploring also the control co-design methodology to …

Vision-Language Integration For Enhanced Locomotion Mode Prediction, Ehsan Ahmadi
LSU Master's Theses
Wearable exoskeletons offer significant potential in enhancing human mobility in industrial environments. However, their adaptability to dynamic, task-intensive settings presents challenges, especially in accurately predicting locomotion modes such as ladder climbing, stair navigation, low-space movement, and obstacle navigation. This research proposes a multimodal framework that integrates visual data and speech commands to improve locomotion mode prediction in unpredictable environments. Multimodal data was collected using smart glasses, capturing both the user’s perspective (field-of-view, FOV) and voice during locomotion tasks. State-of-the-art models—CLIP, ImageBind, and GPT-4o—process these visual and linguistic inputs to predict locomotion activities. The models were evaluated in zero-shot and fine-tuned …

Flexible Docking Method Development For Computer-Aided Drug Design, Luke C. Warrensford
Flexible Docking Method Development For Computer-Aided Drug Design, Luke C. Warrensford
USF Tampa Graduate Theses and Dissertations
Modern drug discovery, the process of identifying or developing novel therapeutic compounds to treat a disease, increasingly relies on computational methods to make the process faster and more efficient. One of the most useful tools in the computer-aided drug design toolbox is molecular docking, the simulation of a protein-ligand complex to determine ligand binding affinity. The results from molecular docking help inform the overall drug discovery process on which compounds have more potential to be potent inhibitors, thus saving time and resources during the later and more expensive stages of drug discovery. Two important considerations of modern docking methods are …

Lengthening Atlantic Hurricane Seasons With Earlier Storm Formation Dates Including Implications From 2020, Barry D. Keim, L. C. Hamilton, V. M. Brown, P. J. Klotzbach, A. B. Lewis, D. T. Thompson
School of Public Health Faculty Publications
This paper analyzes the formation dates of the nth storm in a sequence for all named North Atlantic tropical cyclones (TCs) and assesses whether the intraseasonal length of the Atlantic hurricane season has changed temporally. The record-breaking 2020 season, with 30 named storms, set records for the earliest third TC formation (Cristobal) and from the sixth TC (Fay) onward. Analysis of season length from 1851 to 2022 identifies only one statistically significant breakpoint detected in the early 1970s, roughly coinciding with the introduction of satellite observations. Since 1970, we also find a trend toward longer North Atlantic hurricane seasons. The …

Phagolysosomes Break Down The Membrane Of A Non-Apoptotic Corpse Independent Of Macroautophagy, Shruti Kolli, Cassidy J. Kline, Kimya M. Rad, Ann M. Wehman
Biological Sciences: Faculty Scholarship
Cell corpses must be cleared in an efficient manner to maintain tissue homeostasis and regulate immune responses. Ubiquitin-like Atg8/LC3 family proteins promote the degradation of membranes and internal cargo during both macroautophagy and corpse clearance, raising the question how macroautophagy contributes to corpse clearance. Studying the clearance of non-apoptotic dying polar bodies in Caenorhabditis elegans embryos, we show that the LC3 ortholog LGG-2 is enriched inside the polar body phagolysosome independent of autophagosome formation. We demonstrate that ATG-16.1 and ATG-16.2, which promote membrane association of lipidated Atg8/LC3 proteins, redundantly promote polar body membrane breakdown in phagolysosomes independent of their role …

Research Outputs: 2025-Present
Digital Game-Based Learning (DGBL) uses digital games to enhance engagement and learning, but its efficacy is linked to game features. Leaderboards are a commonly used feature to increase motivation through competition, improving engagement and learning outcomes. However, infinite leaderboards, displaying all players in an ordered ranking based on their scores, can demotivate players depending on their performance and characteristics. This study investigated primary school students’ experience with an infinite leaderboard during a digital maths game intervention. 1389 Irish students participated in a 6-week programme with the game ‘Seven Spells,’ which featured an infinite leaderboard. Player traits and opinions about the …
Unleaded Fuel For General Aviation, Carolina Anderson, Laura Garcia
Unleaded Fuel For General Aviation, Carolina Anderson, Laura Garcia
Sustainability Conference
The Clean Air Act, passed in the late 1970s, mandating the removal of lead from most fuels due its detrimental effects on public health, yet piston-driven aircraft continue to rely on leaded aviation gas (AvGas 100LL). This fuel remains the last lead-containing fuel regulated by the Department of Transportation (DOT). Lead, added as tetraethyl lead (TEL), enhances octane levels and prevents engine detonation, vital for high-compression aircraft engines. In response to the health effects, regulating bodies like the Environmental Protection Agency (EPA) have tightened lead standards and are assessing the risk posed by AvGas. Research links even low-level lead exposure …

Coordination Degree Of Composite Systems And Its Application, Ke Qi, Jiaojun Zhu, Dexiong Teng, Xiao Zheng, Huaiqing Zhang
Bulletin of Chinese Academy of Sciences (Chinese Version)
A composite system (CS) is an organic whole composed of multiple subsystems. It has the property of operating in a coordinated manner through the interconnection and interaction between its subsystems, which could be evaluated by the indicator of coordination degree of composite systems (CDoCS). However, there is currently a lack of quantitative methods for CDoCS and the CDoCS-based technology for composite system optimization. As a result, there is a lack of effective solutions to the problems caused by the disharmony of composite systems such as the mountain-water-forest-farm-lake-grass-sand systems (i.e., composite ecosystems) and the social-economic-natural systems. Therefore, the connotation of CDoCS …

Faculty Journal Articles
Outdoor education programs, such as Forest School, have physical, social-emotional, and academic benefits for children, and teachers trained in nature-based pedagogy are more likely to provide outdoor education opportunities for their students. Incorporating outdoor field experiences in teacher preparation may teach new teachers how to implement nature-based programming. However, little is known about how outdoor field experiences affect pre-service teacher development. Grounded in self-efficacy theory (Bandura, 1977), this mixed-methods study examined in a pretest-posttest design how participating in a 12-week outdoor field experience contributed to pre-service teachers’ (N = 9) knowledge of nature-based pedagogy and their self-efficacy. Participants also completed …

Kernels Of Motor Memory Formation: Temporal Generalization In Bimanual Adaptation, Ian S. Howard, Sae Franklin, David W. Franklin
School of Engineering, Computing and Mathematics
In daily life, we coordinate both simultaneous and sequential bimanual movements to manipulate objects. Our ability to rapidly account for different object dynamics suggests there are neural mechanisms to quickly deal with them. Here we investigate how actions of one arm can serve as a contextual cue for the other arm and facilitate adaptation. Specifically, we examine the temporal characteristics that underlie motor memory formation and recall, by testing the contextual effects of prior, simultaneous, and post contralateral arm movements in both male and female human participants. To do so, we measure their temporal generalization in three bimanual interference tasks. …

Mathematics and Statistics Faculty Publications and Presentations
Liquid droplet dynamics are widely used in biological and engineering applications, which contain complex interfacial instabilities and pattern formation such as droplet merging, splitting, and transport. This paper studies a class of mean field control formulations for these droplet dynamics, which can be used to control and manipulate droplets in applications. We first formulate the droplet dynamics as gradient flows of free energies in modified optimal transport metrics with nonlinear mobilities. We then design an optimal control problem for these gradient flows. As an example, a lubrication equation for a thin volatile liquid film laden with an active suspension is …
