Perry, Leo Celi, Ismini Lourentzou, Luk Hendrik

Teaching, Leadership & Professional Practice Faculty Publications

Student engagement is a key predictor of academic achievement and is closely linked to career awareness, interest, and preparedness. Measuring student engagement during STEM learning is challenging for teachers, given the dynamic and ever-changing nature of these learning environments. Even when engagement data can be collected, leveraging this information to refine and personalise instruction requires significant experience and time. To address this, we are developing Scoutlier EngagEd, a digital teaching assistant that embeds in existing Learning Management Systems (LMS) to automatically and invisibly gather multidimensional data on student engagement and performance during STEM learning. These data are being leveraged to …

On Lexicographic Proof Rules For Probabilistic Termination, Krishnendu Chatterjee, Ehsan Kafshdar Goharshady, Petr Novotný, Jiří Zárevucký, Dorde Zikelic

Research Collection School Of Computing and Information Systems

We consider the almost-sure (a.s.) termination problem for probabilistic programs, which are a stochastic extension of classical imperative programs. Lexicographic ranking functions provide a sound and practical approach for termination of non-probabilistic programs, and their extension to probabilistic programs is achieved via lexicographic ranking supermartingales (LexRSMs). However, LexRSMs introduced in the previous work have a limitation that impedes their automation: all of their components have to be non-negative in all reachable states. This might result in a LexRSM not existing even for simple terminating programs. Our contributions are twofold. First, we introduce a generalization of LexRSMs that allows for some …

Runtime Backdoor Detection For Federated Learning Via Representational Dissimilarity Analysis, Xiyue Zhang, Xiaoyong Xue, Xiaoning Du, Xiaofei Xie, Yang Liu, Meng Sun

Research Collection School Of Computing and Information Systems

Federated learning (FL), as a powerful learning paradigm, trains a shared model by aggregating model updates from distributed clients. However, the decoupling of model learning from local data makes FL highly vulnerable to backdoor attacks, where a single compromised client can poison the shared model. While recent progress has been made in backdoor detection, existing methods face challenges with detection accuracy and runtime effectiveness, particularly when dealing with complex model architectures. In this work, we propose a novel approach to detecting malicious clients in an accurate, stable, and efficient manner. Our method utilizes a sampling-based network representation method to quantify …

Nexusgs: Sparse View Synthesis With Epipolar Depth Priors In 3d Gaussian Splatting, Yulong Zheng, Zicheng Jiang, Shengfeng He, Yandu Sun, Junyu Dong, Huaidong Zhang, Yong Du

Research Collection School Of Computing and Information Systems

Neural Radiance Field (NeRF) and 3D Gaussian Splatting (3DGS) have noticeably advanced photo-realistic novel view synthesis using images from densely spaced camera viewpoints. However, these methods struggle in few-shot scenarios due to limited supervision. In this paper, we present NexusGS, a 3DGS-based approach that enhances novel view synthesis from sparse-view images by directly embedding depth information into point clouds, without relying on complex manual regularizations. Exploiting the inherent epipolar geometry of 3DGS, our method introduces a novel point cloud densification strategy that initializes 3DGS with a dense point cloud, reducing randomness in point placement while preventing over-smoothing and overfitting. Specifically, …

Irhunter: Universal Detection Of Instruction Reordering Vulnerabilities For Enhanced Concurrency In Distributed And Parallel Systems, Guohua Xin, Guangquan Xu, Yao Zhang, Cheng Wen, Cen Zhang, Xiaofei Xie, Neal N. Xiong, Shaoying Liu, Pan Gao

Research Collection School Of Computing and Information Systems

Instruction reordering is an essential optimization technique used in both compilers and multi-core processors to enhance parallelism and resource utilization. Although the original intent of this technique is to benefit the program, some improper reordering can significantly impact the program correctness, which we call instruction reordering vulnerability (IRV). However, existing methods detect IRV by defining CPU instruction reordering rules to schedule execution paths while neglecting compiler reordering, and thus generate false positives that require manual filtering and resulting in inefficiency. To bridge this gap, in this paper, we propose the IRV detection method, , which analyzes IRV characteristics and extracts …

De-Duplicating Silent Compiler Bugs Via Deep Semantic Representation, Junjie Chen, Xingyu Fan, Chen Yang, Shuang Liu, Jun Sun

Research Collection School Of Computing and Information Systems

The compiler bug duplication problem (where many test failures are caused by the same compiler bug) can lead to huge waste of time and resource in diagnosing test failures produced by compiler testing. It is particularly challenging with regard to the silent compiler bugs that do not produce any error messages. To address this problem, multiple white-box techniques were proposed, but they are inapplicable in many practical scenarios. Black-box techniques are more practical, but the existing ones are less effective as they often rely on irrelevant syntactic information. To bridge this gap, we propose a novel black-box technique (BLADE), which …

Gianjara's Ribs: The Ecosystem, Body, Animalia, And Politic, Linus Gomez Ellis

University Honors Theses

This work is a series of four six foot tall full-body portraits of people, which are displayed alongside an actual, physical item or garment present in the associated painting. The purpose of this is to blur the line between the fiction of the individuals depicted and the viewer. By creating "portals" through which to view them as equals in stature, Linus Gomez Ellis is taking something that can be seen in the ecosystem of this fiction and making it into an objective reality. The most enduring, well preserved, and eternal pieces of history and anthropology are tall tales. This ecosystem, …

Examining Long-Term Care For Ncaa Student-Athletes: Improving Concussion Protocols And Healthcare, Sydney Watson

University Honors Theses

Sports-related concussions (SRC) are a significant issue in collegiate athletics, particularly in high-impact sports. While the National Collegiate Athletic Association (NCAA) has protocols for immediate injury management, they don't fully address the long-term effects retired athletes experience. This paper examines whether former NCAA athletes who suffered from SRC should receive more comprehensive concussion-related healthcare. Findings reveal that current NCAA measures, such as baseline assessments and return-to-play protocols, fall short in addressing the lasting physical, cognitive, and emotional challenges of student-athletes who suffered multiple SRC. Protocols and procedures set by professional leagues like the NFL and NHL highlight the NCAA's gaps …

Schauder A Priori Estimates For Poisson's Equation., Janani P. Marasinghe

Research Papers

The Schauder a priori estimate for Poisson's equation is considered. These estimates are important for establishing the smoothness of solutions. Instead of proving the theorem of Schauder a priori estimate directly, this paper focuses on proving the theorem through three reductions. The first reduction normalizes the problem, the second reduction controls the H\"older semi-norm, and finally the third reduction gets a local estimate of the domain. Interpolation inequality for H\"older space and derivative estimates are used throughout this work.

Satellite Infrastructures And Law In The Making Of Planetary Knowledge, Benedict Kingsbury, Yirong Sun

Chicago Journal of International Law

Imaginations of Planet Earth as-a-whole—that is, Earth conceived in planetary terms by wide publics—have been shaped over several decades by the growing capabilities of artificial Earth satellites to image the whole Earth, to specify all locations, and to integrate the Earth’s diverse orbital space with everyday human activities. Different Earth orbits are becoming more densely used, more securitized, more intensely managed from Earth, and more integral to activities on Earth.

This Article focuses on two categories of satellite systems that contribute directly to planetary knowledge, Global Navigation Satellite Systems (GNSS) and Earth Observation Satellite Systems (EOSS). GNSS and EOSS have …

From Human Mapping To Machine Embedding: Uncovering Key Legal Drivers And Deterrents Of Isds Filing Frequencies, Sangchul Park

Chicago Journal of International Law

International investment agreements (IIAs), while intended to prop cross-border investment, have faced persistent criticism for potentially undermining the regulatory sovereignty of developing countries. Various mechanisms have been proposed as alternatives to traditional bilateral investment treaty (BIT) models, often with the goal of curbing investor-state dispute settlement (ISDS) filings. While existing research has uncovered the impact of nonlegal factors, such as macroeconomic crises, little has been done to systematically examine how legal provisions in either major model BITs or ISDS reform toolboxes influence ISDS filing patterns. To address this gap, this Article analyzes the interplay between (i) legal texts of 2,148 …

Technology And The Law Of Jus Ante Bellum, Asaf Lubin

Chicago Journal of International Law

The temporal boundaries of the international rules governing military force are myopic. By focusing only on the initiation and conduct of war, the legal dichotomy between Jus Ad Bellum and Jus In Bello fails to address the critical role of peacetime military preparations in shaping future conflicts. Disruptive military technologies, such as artificial intelligence and cyber offensive capabilities, only further underscore this deficiency. During their pre-war development, these technologies embed countless design choices, hardcoding into their software and user interfaces policy rationales, legal interpretations, and value judgments. Once deployed in battle, these choices have the potential to precondition warfighters and …

Scaffolded Integration: Aligning Ai Literacy With Authentic Assessment Through A Revised Taxonomy In Education, James Hutson

Faculty Scholarship

The accelerating prevalence of generative artificial intelligence in educational and professional spheres necessitates a reevaluation of when and how such technologies are introduced within pedagogical practice. The principal challenge for educators is not merely the imperative to prepare students for an AI-driven world, but rather to ensure that assessment practices remain authentic—providing an accurate measure of what students can independently achieve before leveraging the augmentation potential of intelligent systems. This article contends that the incremental introduction of AI, mapped onto a scaffolded framework aligned with a revised Bloom’s Taxonomy, constitutes a methodologically sound approach for maintaining academic integrity, fostering transferable …

Despite increasing cyber threats to higher education, little research examines how administrative leaders experience and navigate these crises to keep their institutions operational. This hermeneutic phenomenological study explores the lived experiences of seven administrative leaders in three higher education institutions following cyber attacks that disrupted normal operations. This study examined how leaders make sense of cyber crisis experiences and what factors shape their decision-making during response and recovery. Key findings reveal five critical areas of impact. First, cyber attacks can have deep emotional impacts on leaders and staff. Despite these effects, they maintain a strong dedication to enacting the educational …

Weight Recidivism Post-Bariatric Surgery: A Lifestyle Modifications Educational Intervention, Kimeshia N. Johnson

Electronic Theses and Dissertations

Weight recidivism after bariatric surgery is a frustrating phenomenon for bariatric surgery patients and healthcare professionals. A 90-day lifestyle modification intervention for patients at least 18 months postsurgery was performed in the primary care setting to determine if a structured program could promote or maintain weight loss. The intervention aimed to investigate if participation in a structured lifestyle modification program would impact the body mass index of bariatric patients at least 18 months postsurgical intervention. In coordination with a nutritionist specializing in addiction and obesity education, a booklet detailing the guidelines for a 12-week program was provided to 41 bariatric …

Leadership And Peer Support Of Surgeons Post-Adverse Event: A Phenomenological Study, Maxine E. Trent

Electronic Theses and Dissertations

Abstract Surgeons are leaving the active practice of surgery and fewer physicians are pursuing surgical training, as a result the United States is predicted to have a shortage of surgeons until 2050. Surgery hosts a multitude of occupational stressors, one of which is interoperative adverse events and the subsequent experience of second victims. The literature indicates surgeons prefer psychological/emotional support from peers after interoperative adverse events. However, best practices for how to deliver peer and leadership support responses when surgeons experience second victims have not been established. This was a phenomenological qualitative study targeting practicing surgeons across the United States. …

Technology And The Unique Challenges Of Applying Law To The Realm Of Outer Space And Space Activities, F.G. Von Der Dunk

Chicago Journal of International Law

For better or worse, technology at heart is—except to the extent that artificial intelligence fundamentally becomes involved—not so much a creator as a facilitator and enhancer of human acts, actions and activities, allowing them to become more effective, less costly, or sometimes even just merely feasible. Perhaps nowhere that is more pertinent then when it comes to human activities in outer space, which are still overwhelmingly conducted remotely and hence crucially dependent on technology. Given that “the law” has always been geared to address humans and their acts, actions, and activities, this gives rise to a rather special approach to …
