Multi-Period Risk-Aware Procurement Optimization Under Covid-19 Disruption, Jonathan Chase, Hoong Chuin Lau, Jinfeng Yang, Lu Liu

Research Collection School Of Computing and Information Systems

Supply chain resilience has been a topic of active research in the operations research and AI communities for several years, but the COVID-19 pandemic threw the frailties of global supply chains into sharp relief. Disruptions and delays caused by fresh outbreaks leading to lockdowns, put severe strain on supply chains in many industries. In this work we develop lockdown-resilient procurement capabilities for a global technology company. First, through analysis of lockdown data from China we develop a logarithmic regression-based lockdown prediction method to complement a supplier risk metric for conventional risks. Second, we develop a multi-period stochastic optimization model that …

Teaching Diffusion Models To Ground Alpha Matte, Tianyi Xiang, Weiying Zheng, Yutao Jiang, Tingrui Shen, Hewei Yu, Yangyang Xu, Shengfeng He

Research Collection School Of Computing and Information Systems

The power of visual language models is showcased in visual understanding tasks, where language-guided models achieve impressive flexibility and precision. In this paper, we ex tend this capability to the challenging domain of image matting by framing it as a soft grounding problem, enabling a single diffusion model to handle diverse objects, textures, and transparencies, all directed by descriptive text prompts. Our method teaches the diffusion model to ground alpha mattes by guiding it through a process of instance-level localization and transparency estimation. First, we introduce an intermediate objective that trains the model to accurately localize semantic components of the …

Tactile Data Comics: Combining Step-By-Step Presentation Of Tactile Graphics With Verbal Narration For The Blind And Visually Impaired, Yang Jiao, Ruoting Sun, Rong Luo, Xiwen Yao, Xinran She, Kotaro Hara, Yuewen Zhang, Xinyi Fu

Research Collection School Of Computing and Information Systems

Tactile graphics on a refreshable display have proven effective in enabling visually impaired people to comprehend pictorial content. To further evaluate the effectiveness of refreshable tactile displays in blind education, we designed tactile data comics, a method that combines step-by-step presentation of tactile graphics with verbal narration. We conducted a user study with sixteen visually impaired students to compare tactile data comics against verbal-only and static tactile graphics. Our findings show that tactile data comics significantly improve participants’ comprehension and engagement during the learning experience. These empirical results suggest that the integration of refreshable tactile displays and tactile data comics …

Emoshortcuts: Emotionally Expressive Body Augmentation For Social Mixed Reality Avatars, Hyuna Seo, Youngki Lee, Rajesh Krishna Balan, Thivya Kandappu

Research Collection School Of Computing and Information Systems

We present EmoShortcuts1, a novel social Mixed Reality (MR) framework that enhances emotional expression by dynamically augmenting avatar body gestures to reflect users’ emotional states. While social MR enables immersive remote interactions through avatars, conveying emotions remains challenging due to limitations in head-mounted display (HMD) tracking (e.g., missing lower-body movements, such as stomping or defensive postures), and users’ tendency to deprioritize nonverbal expressions during multitasking. EmoShortcuts addresses these challenges by introducing an augmentation framework that generates expressive body gestures even when users’ physical movements are restricted. We conducted a formative study with 12 participants to identify key challenges in emotional …

Learn To Fly: Enabling Deep Learning Based Perception And Control In Aerial Robotics, Krishna Muvva

School of Computing: Dissertations, Theses, and Student Research

Uncrewed Aerial Vehicles (UAVs) are increasingly deployed in dynamic, GPS degraded, and cluttered environments, yet their autonomy remains fundamentally constrained by limitations in onboard perception and real-time control. This dissertation addresses these challenges by proposing a unified framework that co-designs deep learning-based perception and model-based control, organized around three core thrusts: Learn to Track, Learn to Localize, and Learn to Evade.

Learn to Track develops dynamic and adaptive perception control mechanisms that optimize CNN inference for target tracking. A control-aware CNN framework dynamically adjusts inference frequency based on UAV motion, reducing latency while maintaining visual lock. An adaptive CNN with …

Exudation Entomology, John Buchanan

Department of Entomology: Distance Master of Science Projects

My master's project is exudation entomology. I propose a new area of entomology that will renew and reshape the science, answer questions that have been explored, and open new questions that have yet to be asked.

Exudation entomology is the study of exudates from arthropods. This includes (but is not limited to) honey, saliva, silk, secretions, venom, pheromones, paper, wax, and more. Other properties, such as bioluminescence, sounds, and odors, are also included. Exudation entomology will explore the chemical makeup of exudates, the anatomical mechanisms for how the arthropod produces the exudate, why the exudate is essential for arthropods and …

Colaborate: A Mixed-Methods Approach To Enabling Inclusive Dialogue Of Emotional Regulation Resources For Young Autistic Children, Sarai E. Deese

Senior Theses

Emotion regulation (ER) is a critical developmental milestone and is often delayed or more difficult for autistic children. Publicly available resources for birth-5-year-olds with autism could benefit significantly by integrating the values of and information provided by autistic adults. However, existing resources may have poor accessibility, acceptability, and feasibility according to different groups within the autism community, creating a significant gap in effective support. This mixed-methods study investigated ER experiences, resource knowledge, and resource desire among autistic adults (N=4; Stage 1) and caregivers of young autistic children (N=4; Stage 2) to inform the development of acceptable ER supports. In Stage …

Investigating The Effects Of Cbd And Caffeine Interaction On Embryonic Development In Xenopus Laevis, Jeanesia M. Pierre

Theses

This study examined the interactive effects of cannabidiol (CBD) and caffeine on Xenopus laevis embryos over a 96-hour exposure period. Developmental toxicity was assessed using toxic unit isobole analysis, with LC₅₀, EC₅₀, and teratogenic index (TI) values calculated for CBD, caffeine, and mixtures at 3:1, 1:1, and 1:3 ratios.

Results showed that mixtures produced concentration-dependent interactions. When caffeine levels were higher, the mixtures displayed synergistic toxicity; as the proportion of CBD increased, the interaction shifted toward a concentration-addition model. Mortality was elevated in mixtures relative to single-compound exposures, while malformation rates decreased, indicating reduced teratogenicity. Overall, findings suggest that CBD …

Genome-Wide Identification Of Essential Genes For Microbial Insecticide Bioremediation, Mary Snook

AES Theses

Insecticides pose a threat to ecological, wildlife and human health when they are carried in runoff water from agricultural fields to surface and ground waters. Microbial bioremediation provides a promising avenue for degrading and removing these pollutants from runoff water before they dissipate into downstream ecosystems. While effective bioremediators for various target pesticides have been identified, we do not yet understand exactly how microbes degrade insecticides in most cases. In this study, I examined three bacterial strains with the ability to metabolize imidacloprid (strain Imidl Y) or malathion (strains Mal4 and Mal6), both common insecticides, and used transposon-mediated mutagenesis to …

Lung Cancer In Patients Of African Descent: A Transcontinental Review Of Epidemiology, Disparities, Outcomes, And Opportunities For Equity In Africa, North America, South America, And The Caribbean, Elvis Obomanu, Colton Jones, Verna Vanderpuye, Nazik Hammad

Division of Internal Medicine Faculty Papers & Presentations

Lung cancer in people of African descent is characterized by transcontinental disparities driven by epidemiologic heterogeneity, systemic inequities, and unequal access to health care. Globally, lung cancer incidence and mortality rates vary; however, underdiagnosis and late-stage presentation in low- and middle-income countries obscure the true prevalence of lung cancer because of limited cancer registries and diagnostic infrastructure. In Africa, most patients with lung cancer present at an advanced stage, primarily because of health illiteracy, misdiagnosis, delayed referrals, and inadequate treatment infrastructure. Although tobacco smoking remains a dominant risk factor worldwide, African populations are disproportionately exposed to environmental and occupational hazards, …

Computational Dataset Of Cetyl Trimethyl Ammonium-Anion Complex Structures And Simulated Infrared Spectra, Arun K. Sharma, Owen Mcmillan

Biology, Agriculture and Chemistry Faculty Publications and Presentations

This dataset presents computationally derived geometries and vibrational spectra of cetyl trimethyl ammonium ion pairs formed with three environmentally and chemically relevant anions: bisulfate, nitrate, and methyl sulfonate. Data were obtained using quantum chemical calculations performed using the Gaussian 16 software package, utilizing the ONIOM method at the second-order Møller–Plesset perturbation theory (MP2) level. To account for solvent effects and electrostatic screening, calculations incorporated an implicit solvent environment via the polarizable continuum model (PCM). The dataset includes optimized geometric coordinates, harmonic vibrational frequencies, and simulated infrared (IR) spectra for each cetyl trimethyl ammonium-anion pair. Additional computational details, including input parameters, …

Asymmetric Interdependence In Tunisian–Algerian Energy Relations, Samuel Harlow

Tunisia and Italy: Politics and Religious Integration in the Mediterranean

This research interprets contemporary Tunisian–Algerian relations through the

lens of asymmetric interdependence, offering a nuanced analysis of the power

dynamics embedded in their energy relationship. Employing a disciplined

configurative case study design, the study systematically applies established

theories of asymmetric interdependence, particularly relative vulnerability and

the influence effect, to energy trade data, oil and natural gas infrastructure, and

patterns of fiscal and emergency assistance. The analysis demonstrates that

Algerian energy policy and financial support have contributed to an

interdependent relationship in which Algeria is relatively less vulnerable than

Tunisia, generating latent conditions for economic influence without asserting

that coercive instruments …

Navigating Survival Without Rights: The Case Of Sub-Saharan And Sudanese Migrants In Tunisia, Amel Mohdali

Tunisia and Italy: Politics and Religious Integration in the Mediterranean

This study examines irregular migration and the lived experiences of migrants and asylum seekers in Tunisia, focusing on how individuals navigate prolonged transit in the absence of legal status, protection, and formal rights. Based on qualitative interviews with eight migrants from Sub-Saharan Africa, and Sudanese refugees displaced by mass violence, the research approaches migration not as a single act of movement but as an extended condition shaped by housing, employment, mobility, and access to safety. Across interviews, Tunisia is described as a transit country that unexpectedly became a site of residence due to expired visas, exit fines, and restricted onward …

The Public Health Cost Of Online Behavioral Targeting, Arthi Annadurai

Vanderbilt Journal of Entertainment & Technology Law

Behavioral targeting is an increasingly popular marketing technique that utilizes users’ online activity to personalize advertisements aimed at consumers. However, since personalized advertisements aim to influence individual consumers, behavioral targeting can negatively impact vulnerable users. For instance, it may reinforce harmful behaviors—like showing alcohol advertisements to individuals with alcohol dependency—or worsen mental health struggles, such as prolonging grief by continuing to serve parenting advertisements to those mourning the loss of a child. These practices can perpetuate harmful behaviors, such as relapse or heightened psychological distress, and contribute to long-term health problems, such as addiction or other mental health problems, creating …
