Cognitive Fatigue Detection Using Photoplethysmography (Ppg) And Reaction Time Data, Anhar Sami Mohammed, Prajoy Podder, Maciej Jan Zawodniok, Cihan Dagli

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a framework for real-time cognitive fatigue detection among shift workers using an integrated approach that combines photoplethysmography (PPG) data and reaction time analysis with advanced deep learning models, including Long Short-Term Memory (LSTM) networks and Feedforward Neural Networks (FNNs). The system leverages heart rate variability (HRV) and reaction time data to identify fatigue indicators. The results demonstrate significant performance, with the first FNN model achieving a test accuracy of 98.94% and a loss of 0.2928, while the second FNN model achieved the same accuracy with a slightly higher loss of 0.3089. The LSTM model, designed for sequential …

Online Learning-Driven Human Intent Estimation And Control For Human-Robot Interaction, Irfan Ganie, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a novel Stackelberg-game theoretic multilayer-online learning framework for cooperative control of nonlinear Physical Human-Robot Interaction (pHRI), where the human is modeled as the leader guiding a robot follower. This hierarchical interaction is captured as a dynamic Stackelberg game, with the human's intention estimated in real-time through online multilayer neural networks (MNNs). We introduce SVD-based weight update laws for actor-critic MNNs, which approximate value functions and control inputs for both human and robot, eliminating the need for predefined basis functions. In this framework, the human objective is first inferred and used to guide the robot actions by shaping …

Multi-Model Safe Neuro-Optimal Output Tracking Control Of Autonomous Surface Vessels With Explainable Ai, Behzad Farzanegan, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a safety-aware deep reinforcement learning (DRL)-based trajectory tracking control of autonomous surface vessels (ASVs). A multilayer neural network (MNN) observer estimates the ASV's state and uncertain dynamics. By utilizing the estimate state vector from the observer, a safety-aware DRL-based optimal policy is formulated using control barrier function (CBF) and Karush-Kuhn-Tucker (KKT) conditions. An actor-critic MNN with singular value decomposition (SVD)-based update mitigates vanishing gradients. To enhance adaptability, an online safe lifelong learning (SLL) scheme counters catastrophic forgetting across varying ASV dynamics. The Shapley Additive Explanations (SHAP) method identifies key features influencing the control policy. Simulations on an …

Aperture-Based Fss For Dielectric Thickness Sensing, Alexander Hook, Gage Donahue, Kristen M. Donnell

Electrical and Computer Engineering Faculty Research & Creative Works

Frequency selective surfaces (FSSs) are planar arrays of patch- or aperture-based elements that have a particular transmissive or reflective response. As FSS performance is affected by changes in the local (to the FSS) environment, FSSs may be used to detect changes in strain, temperature, or nearby material (substructure) thickness, amongst other parameters. To this end, an aperture-based FSS can be considered as a sensor for substructure thickness monitoring for surface mounted sensing scenarios. An aperture-based design was selected due to its ability to operate in reflection mode (and hence a one-sided measurement) without the need for a conductive backplane. In …

Reinforcement Learning-Based Nonlinear Optimal Discrete-Time Control Of Power Systems, Vijay Kumar Singh, Behzad Farzanegan, S. Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents a partially model-free adaptive optimal tracking control method for power systems, specifically targeting a synchronous generator connected through a reactive transmission line. By integrating the tracking error dynamics with reference trajectory dynamics, an augmented system is created. A discounted performance function is introduced to address the nonlinear tracking problem optimally. Unlike traditional methods that compute feedforward and feedback terms separately, the proposed approach calculates both simultaneously by minimizing the discounted performance function. The discrete-time tracking Bellman and Hamilton-Jacobi-Bellman (HJB) equations are derived, and a reinforcement learning (RL)-based technique is employed to solve the optimal policy online without …

A Cost-Effective Nilm Solution With Three-Point Labelling And Non-Causal Convolution Technique, Yanan Zhang, Gan Zhou, Yanjun Feng, Zhan Liu, Li Huang, Zhi Li, Rui Bo

Electrical and Computer Engineering Faculty Research & Creative Works

Although deep learning is increasingly promising in the field of Non-Intrusive Load Monitoring (NILM) these days, the high costs of data recording and labelling represent a significant challenge for the training of supervised models. To address this, a cost-effective sequence-to-points NILM solution is proposed, integrating three-point labelling with non-causal convolution techniques. The approach introduces a semi-automatic labelling framework for obtaining NILM three-point data, which provides a low-cost data collection and labelling solution for large-scale applications. Then, a novel loss function combining coordinate loss and confidence loss is developed to address the positional misalignment and negative sample confusion in sequence-to-points scenario …

When One Door Closes: Legal Education And Racial Justice After Students For Fair Admissions, Michael I. Meyerson

Nebraska Law Review

In Students for Fair Admissions, Inc. v. President & Fellows of Harvard College, the Supreme Court ruled that the Equal Protection Clause and Title VI of the Civil Rights Act of 1964 prohibited colleges and universities from using race as a factor in admissions decisions. Many have feared that this ruling portends the end of racial diversity in higher education. Law schools, however, can choose to treat this decision as creating a fresh opportunity to pursue racial justice in a comprehensive and meaningful way. Most of the early scholarly writing on Students for Fair Admissions focused on either its …

Uncle Sam And The Sea: An Administrative Red Herring, Heather Haratsis

Nebraska Law Review

“The law must be stable and yet it cannot stand still.”¹

Compared to the Old Man and the Sea, the administrative state’s situation does not seem all that different.² The idea of the administrative state has been around since the birth of civilization. There has always been a need for caretakers to protect the best interests of their people. While the administrative state is a testament of our society’s resilience and loyalty to the idea of one union providing for public good; it has become the Santiago.³ An administrative state is only as good as its …

A Judiciary Without Trust?, Brandon J. Johnson

Nebraska Law Review

Public hand wringing over waning faith in the Supreme Court, this Essay contends, mistakes symptom for cause. The real crisis is not distrust but the Court’s persistent failure to earn trust in the first place. Trust is a feeling; trustworthiness is a record. This Essay adopts a common understanding of trustworthiness that evaluates the demonstrated ability of the trusted party to protect the vulnerable trusting parties, and analyzes the Court’s trustworthiness against that yardstick. From Dred Scott, Plessy, and Korematsu to modern “shadow docket” interventions and undisclosed donor funded travel, the Court has too often shown itself untrustworthy …

Not The “Mere Creature” Of Big Tech: The Constitutionality Of Parental Consent Laws For Minors’ Social Media Accounts, Kat Turco

Nebraska Law Review

A growing number of states have passed laws requiring social media platforms to obtain parental consent before granting accounts to minors to combat rising mental health issues, cyberbullying, and screen addiction. Although well intentioned, every such law has been enjoined in the lower courts, and the Supreme Court has yet to address whether laws requiring parental consent for minors’ social‑media accounts violate the First Amendment. This Comment argues that lower courts have miscast such statutes as content‑based speech restrictions requiring strict scrutiny under Brown v. Entertainment Merchants’ Association. Parental consent laws differ from the content-based statute at issue in …

The Self-Erasure Of The Eeoc In Bostock V. Clayton County, Nicholas B. Mauer

Nebraska Law Review

During the decade before the Supreme Court decided Bostock v. Clayton County, the Equal Employment Opportunity Commission (“EEOC”) interpreted Title VII to prohibit employment discrimination based on gender identity and sexual orientation. Through informal adjudication, independent litigation, and nonacquiescence, the EEOC successfully etched its interpretation of Title VII into law without receiving Chevron deference. The agency made arguments about the meaning of Title VII that succeeded in lower courts and eventually at the Supreme Court. However, the majority opinion in Bostock never mentioned the EEOC’s near-decade of work. Thus, the EEOC’s role in Bostock is both a potential model …

A Study Of The Tap In Center Movement: How Collaboration In The Legal System Is Reducing The Negative Impact Of Bench Warrants And Restoring Justice In Communities, Patrick C. Brayer

Nebraska Law Review

While many aspects of the criminal legal system have been criticized for the harm judicial institutions inflict on communities, a unique legal initiative is garnering praise from observers across the nation. What started as a local effort to help residents withdraw bench warrants during the COVID-19 Pandemic has blossomed into four independent legal service centers in three separate Midwest metropolitan areas called Tap In Centers. The primary mission of the Centers is the recalling of bench warrants issued when criminal defendants fail to appear for court or pay a fine; however, the needs of the individual and the community guide …

Reversible Degradation Of Peptidoglycan By Lytic Transglycosylases, Aaron Devereaux

Theses and Dissertations (Comprehensive)

Antimicrobial resistance continues to be a burden on the global healthcare system with an estimated cost of billions of dollars and millions of deaths each year. Recently, there has been little to no development on new antibiotics to treat bacterial infection, and any that are developed become resisted to within a few years. Both Gram-positive and Gram-negative bacteria contain a mesh-like layer called peptidoglycan (PG) that surrounds their cells providing strength, cell shape, and protection from their environments. This layer is a polymer of N-acetylmuramic acid (MurNAc) and N-acetylglucosamine (GlcNAc) connected via a b-1,4-glycosidic bond, with each strand being cross-linked …

You’Ve Got Mail—Or Not? The Deepening, Decades-Long Circuit Split Surrounding The Tax Filing Mailbox Rule, Colton Franks

SMU Law Review

Tax filing deadlines have always been a source of anxiety for U.S. citizens, and the law surrounding the subject is equally perplexing. Federal courts developed a mailbox rule to determine whether a document is timely filed through the mail, but the federal circuits did not agree on how it functioned. Congress subsequently passed Section 7502 of the Internal Revenue Code to clear up confusion among the circuits. However, this only sparked a new debate—whether the statute takes the place of the common law mailbox rule or merely adds another avenue for the taxpayer to prove timely filing. This circuit split …

After Identity: Reverse Discrimination, Anti-Essentialism, And The Future Of Title Vii, Maayan Sudai, Lihi Yona

SMU Law Review

This Article argues that the Supreme Court’s unanimous decision in Ames v. Ohio Department of Youth Services marks a turning point in Title VII’s long-standing struggle with identity. By striking down the “background circumstances” rule, a doctrine that required majority-group plaintiffs to meet a heightened evidentiary burden, the Court appeared at first glance to reaffirm its steady march toward strict anticlassification. We offer a different reading. We contend that Ames gestures toward a third, overlooked normative framework within antidiscrimination law: anti-essentialism. This framework, rooted in feminist, critical race, and queer theory, rejects both the rigidity of anticlassification and the categorical …

Socially Responsible Ai In The Gpt Era, Yussuf A. Aleem

SMU Law Review

Recent advancements in artificial intelligence (AI) showcase its rapid evolution and promise, with the potential to profoundly transform decision-making, self-expression, and even the practice of law. However, AI also presents formidable challenges, including the further entrenchment of societal inequalities, widespread labor disruption, and existential threats to humanity. Modern AI systems show early signs of general intelligence, enabling them to perform a wide range of tasks beyond those of chatbots in both virtual and physical environments. Despite industry assurances of responsible AI development, these technologies are easily exploited and often exhibit troubling behaviors that even their creators struggle to understand.

Ready Or Not: How Congressional Dysfunction And Loper Bright Enterprises V. Raimondo Will Shift U.S. Regulation Of Emerging Technologies To The Federal Bench, Michelle Benedetto Neitz

SMU Law Review

This Article is the first in legal academic literature to consider how the power shift generated by Congressional dysfunction and the Supreme Court’s decision in Loper Bright Enterprises v. Raimondo will affect emerging technology law. Power is moving toward the judicial branch of government— and away from the legislative and executive branches. As a result, federal courts will now take a leading role in the evolution of emerging technology law in the United States.

Unfortunately, the federal judiciary is not prepared for this new era. Drawing from the information processing theory, this Article explains why federal judges will be deciding …

Roaring Skies: The Law Of Supersonic Commercial Flight And Arguments For Its Return, Caleb S. Dorris

Journal of Air Law and Commerce

The prospect of supersonic commercial flight is no longer confined to history; it is reemerging as a viable transportation model in the 21st century. With major airlines placing orders for next-generation supersonic aircraft and regulatory agencies, including the Federal Aviation Administration (FAA) and the International Civil Aviation Organization (ICAO), reconsidering longstanding restrictions, the return of supersonic flight is imminent. This article examines the legal, regulatory, and policy considerations that have shaped supersonic aviation’s trajectory and explores the challenges that remain for its full reintroduction into global airspace.

First, this article surveys the historical rise and fall of supersonic passenger aviation, …

Airplane!: Does The Federal Aviation Act Preempt State Law Design Defect Claims?, Max Birmingham

Journal of Air Law and Commerce

Which level of government—state or federal—has jurisdiction to set safety standards for aviation defect design is a nuanced issue. Generally speaking, federal law preempts state law in this context by occupying the field through a regulatory scheme that permeates aviation safety. The Federal Aviation Act of 1958 (FAAct) confers its namesake agency—the Federal Aviation Administration (FAA)—the powers to prescribe the “minimum standards required in the interest of safety.” The word “minimum” has been seized upon by those on the state side of the debate to advocate that it means the floor. And they contend that those in the Union have …

Air Strikes In Myanmar - An Analysis Under International Law, Jacob Davis

Journal of Air Law and Commerce

Since the Russian invasion of Ukraine in 2022, and the reignited Israel-Palestine conflict in 2023, international law regulating the use of air power has been put to the test. The use of air strikes in civilian areas has put this shortcoming at the forefront of conversation about the use of force, and what constitutes a war crime in modern conflict.

This conversation has centered around the two aforementioned conflicts but has left other international disputes out of the discussion. In particular the civil war in Myanmar, a bloody conflict which follows decades of ethnic violence, political stratification, and a successful …

Let’S Jettison Some Executive Perks: Exploring The Sec And Irs Approaches To Personal Use Of Corporate Aircraft, Christine Lane

Journal of Air Law and Commerce

In 2023, 46% of the S&P 500 companies provided personal use of corporate aircraft to their chief executive officers, and 31% provided this perk to other named executive officers. This type of executive compensation has notoriously garnered much attention from the media, given the large amount of investor money spent on personal travel and the environmental impacts of flying private. In addition, the line between personal travel and business travel is often blurred, and the media has tracked flight paths of corporate aircraft to speculate that some flights may be incorrectly categorized as business trips when the jets land and …

What Does It Mean To "Humanize" Online Teaching?, Dana L. Rognlie, Kathryn E. Frazier, Elizabeth A. Siler

Philosophy Faculty Publications

[Introduction] "Humanizing" the online classroom is widely acknowledged as a feminist goal (e.g., Pacansky-Brock et al., 2020). Yet the project of humanizing has a complex history in the academy and beyond, with elements of this history often misaligned or directly opposed to what might be considered "feminist" goals. Feminist philosophers have long critiqued the neutral-human-as-masculine default (Beauvoir, 2010; Irigaray, 1993; Lloyd, 1993), and decolonial and antiracist scholars have highlighted the racist legacy of projects that aim to qualify humanity (Cameron, 2021) and of programs designed to humanize the Other (Berenstain, 2020, Foucault, 1979; See Malone & Malone, 2015, on the …

Grading Legal Research, Julie Tedjeske Crane

Faculty Scholarship

Law school grading practices often conflict with legal research instruction goals. Small class sizes render norm-referenced (curved) grading unreliable, and the emphasis on ranking students detracts from learning essential skills. Drawing on scholarship on legal education and other disciplines, this article examines several grading approaches that may better serve students and instructors, including criteria-referenced, specification-based, and equitable grading systems. It offers practical suggestions for improving grading practices, such as working with colleagues on assessment design, being intentional about grading formative work, and using anonymous grading. The article concludes with a call for more discussion about grading in legal research courses.
