What are nonfarming residents' and farmers' levels of support for various interventions outlined in previous research on water quality issues in local streams and waterways and the CBW? What is the level of nonfarming residents' and …

Ecological Interactions Of Cougars, Deer, And Wild Pigs In The Central Coast Range, California, Mitchell A. Parsons

All Graduate Theses and Dissertations, Fall 2023 to Present

Wild pigs are an introduced species in the Americas that negatively affect ecosystems in many ways. Previous research has documented their negative effects on water quality and vegetation and their potential to spread disease among wildlife, domestic animals, and humans. However, how wild pigs affect predator-prey interactions between native wildlife has received little attention. This research explores multiple interactions between wild pigs, a native predator (cougars), and a native prey (black-tailed deer). First, I studies cougar diet to understand how frequently pigs are used as prey. During this project, I also placed wildlife cameras at cougar killed prey to monitor …

Designing Technology-Enriched Learning Environments: The Effects Of An Agent-Based Computer Model On Biology Students' Understanding Of The Covid-19 Pandemic And The Nature Of Models In Science, April Sullivan

All Graduate Theses and Dissertations, Fall 2023 to Present

Science education researchers have called for increased attention to the science practice of modeling to engage students in authentic scientific inquiry. A major challenge to integrating the modeling practice into science instruction is that students tend to conceptualize models as static end-products of research rather than generative tools for theory-building. Engaging students in using computer models, specifically agent-based computer models (ABMs), to explain and predict scientific phenomena could improve students' understanding of models in science. In this design-based research project I investigate the effects of an ABM-supported learning environment on high-school biology students' understanding of the COVID-19 pandemic and the …

Examining The Impacts Of Demographics, Individual Experiences, And Perceptions On Range Anxiety And Electric Vehicle Road Trips, Joshua Ward

All Graduate Theses and Dissertations, Fall 2023 to Present

Range anxiety is perhaps the most widely cited barrier to electric vehicle (EV) adoption and use. Range anxiety is generally defined as a general fear that an EV has insufficient battery range or that there is insufficient charging infrastructure to travel from one place to another. Although this barrier is widely cited, there is little research that investigates how EV drivers experience range anxiety and how it might vary based on personal characteristics, perceptions, and experiences. Data on long-distance EV trips is also scarce in the United States and mainly limited to personal stories of an EV road trip.

Delidar: Decoupling Lidars For Pervasive Spatial Computing, Kanatta Gamage Ramesh Darshana Rathnayake, Razat Sutradhar, Abbaas A. M. Nishar, Weerakoon Dulaj S., Ashwin Ashok, Archan Misra

Research Collection School Of Computing and Information Systems

Unbounded proliferation of LiDAR-equipped pervasive devices generates two challenges: (a) mutual interference among emitters and (b) significantly higher sensing energy overhead. We propose a fundamentally different approach for LiDAR sensing, in indoor spaces, that decouples the sensor’s emitter and receiver components. Our proposed approach, called DeLiDAR, centralizes the emitter functionality in one or more stationary nodes that continually emit pulses; this decoupling allows each mobile LiDAR sensor to be an ultra-low power, pure receiver unit consisting solely of passive multiple photodiodes. We explain how the emitter can utilize VLC-based encoding of its pulses to convey parameter settings that allow a …

Shield-U: Safeguarding Traffic Sign Recognition Against Perturbation Attacks, Shengmin Xu, Jianfei Sun, Hangcheng Cao, Yulan Gao, Ziyang He, Cong Wu

Research Collection School Of Computing and Information Systems

Traffic sign recognition systems are crucial for the navigation and situation awareness of autonomous vehicles. They leverage deep learning technologies to swiftly and accurately identify traffic signs, even in the most challenging traffic environments. However, security researchers have uncovered a critical vulnerability in these systems: learning-based TSRs are particularly susceptible to physical-world perturbation attacks. Through subtle modifications (i.e., attaching well-designed patches on traffic signs), attackers can deceive the recognition system into making erroneous judgments, which can further lead to serious traffic accidents. Although several defense mechanisms have been proposed to enhance the security of sign recognition systems, these solutions generally …

A Comprehensive Study On Static Application Security Testing (Sast) Tools For Android, Jingyun Zhu, Kaixuan Li, Sen Chen, Lingling Fan, Junjie Wang, Xiaofei Xie

Research Collection School Of Computing and Information Systems

To identify security vulnerabilities in Android applications, numerous static application security testing (SAST) tools have been proposed. However, it poses significant challenges to assess their overall performance on diverse vulnerability types. The task is non-trivial and poses considerable challenges. Firstly, the absence of a unified evaluation platform for defining and describing tools’ supported vulnerability types, coupled with the lack of normalization for the intricate and varied reports generated by different tools, significantly adds to the complexity. Secondly, there is a scarcity of adequate benchmarks, particularly those derived from real-world scenarios. To address these problems, we are the first to propose …

Within this ecosystem, Android permissions play a crucial role in managing access to resources, with system permissions controlled by system apps and custom permissions declared by third-party apps. However, the security of custom permissions has not received enough attention from the mobile security community, resulting in a lack of thorough evaluation of security practices for app developers using custom permissions. This study systematically evaluated the misconfiguration of custom permissions by Android app developers. It is …

User Acceptance Of Advice By Ai Agents: Expectation-System Fit Perspective, Jingyuan Cai, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

Algorithms have increasing influence on our daily decisions, especially when the recommendations are presented by human-like AI agents. This study applies the Theory of Effective Use to investigate how the fit between the user’s role expectation for an AI agent and the agent’s interaction style impacts AI advice adoption. We proposed a new concept termed Perceived Expectation-System Fit (PESF) and empirically examined its impact on user perceptions and advice acceptance. We found that low PESF reduces advice acceptance by diminishing cognitive and affective trust in the AI agent. Furthermore, increased algorithm transparency increases PESF's impact on decision-making. Our findings provide …

Not All Samples Are Created Equal: Task-Aware Informative Sampling And Adaptive Inference For Efficient Edge Ai, Rebati Gaire

School of Computing: Dissertations, Theses, and Student Research

The rapid proliferation of Internet of Things (IoT) devices has resulted in an unprecedented influx of data generated at the edge by billions of sensors. Traditional approaches relying on cloud-based processing are increasingly inadequate due to constraints in bandwidth, latency, and privacy. Edge computing has emerged as a transformative paradigm, enabling real-time data processing and decision-making by decentralizing computation to the edge. While the integration of deep learning into edge environments—termed edge intelligence—promises autonomous and personalized operations, it is hindered by challenges such as limited computational resources, energy constraints, and data redundancies.

This thesis addresses these challenges by presenting three …

Using Symbolic Execution To Analyze The Hardware Tcp Protocol, Nianhang Hu

School of Computing: Dissertations, Theses, and Student Research

As the demand for high performance and flexible networking capabilities increases, the shift from software to hardware implementations of stateful networking functions (such as TCP) is becoming increasingly important. This transition not only enhances processing efficiency in modern networking environments where data transmission rates are rising, but it also reduces the inherent CPU overhead found in software implementations, allowing hardware devices to handle network traffic more efficiently. However, validating the correctness of these hardware designs poses significant challenges due to the complex timing requirements and the vast input space associated with packet-level properties.

The verification of packet-level properties requires coverage …

This study, therefore, sought to assess the strategies for competition in libraries and information centers and develop a framework that can be deployed in libraries and information centers for competitive advantage. The study adopted a conceptual and qualitative approach to research. Based on the review and analysis, the researcher developed a framework that suggests that technology (infrastructure, social media systems, gamification, and artificial intelligence) …

Artificial Intelligence And Cracks In The Foundation Of Intellectual Property, Robin Feldman

UC Law Journal

Our implicit image of progress and the standards we use to calibrate human contribution to progress are quietly at risk from the onslaught of artificial intelligence (AI). AI has the potential to significantly shrink the pool of creative work that is protectable by intellectual property (IP) law and the range of information that is protectable, as well as shrinking the value proposition of IP regimes themselves.

As society faces this changing landscape, we must tread carefully to distinguish fears about AI from the task of defining the boundaries of intellectual property, whose theoretic concepts aren’t designed to bear such weighty …

Harnessing Collective Structure Knowledge In Data Augmentation For Graph Neural Networks, Rongrong Ma, Guansong Pang, Ling Chen

Research Collection School Of Computing and Information Systems

Graph neural networks (GNNs) have achieved state-of-the-art performance in graph representation learning. Message passing neural networks, which learn representations through recursively aggregating information from each node and its neighbors, are among the most commonly-used GNNs. However, a wealth of structural information of individual nodes and full graphs is often ignored in such process, which restricts the expressive power of GNNs. Various graph data augmentation methods that enable the message passing with richer structure knowledge have been introduced as one main way to tackle this issue, but they are often focused on individual structure features and difficult to scale up with …

Echo And Drag As Resistance: Coloniality, Queerness, And Practices Of Reading Student Texts, Joshua Barsczewski, Florianne Jimenez

The Journal of the Assembly for Expanded Perspectives on Learning

In this article, a postcolonial theorist and a queer studies scholar reconsider the role of student resistance in Writing Studies’ social justice turn, arguing for a way of reading student texts that accounts for why students might choose to take up social justice or not in their own writing. Through examples from their ongoing research projects, the writers discuss how students’ resistance surfaced not as visible and explicit signs of a changed epistemological framework or political perspective, but as a series of normative rhetorical choices that made space for more transgressive or subversive possibilities.

Polymeric Sumo-2/3 Chain Signals Are Antagonistically Regulated By The Sumo-Targeted Ubiquitin E3 Ligase Rnf4 And The Sumo-Specific Isopeptidase Senp6, Shaniah A. Irving M.A., Xiang-Dong Zhang Ph.D.

Biology Theses

Polymeric SUMO-2/3 chain modification is critical for chromosome segregation, DNA damage repair, genome stability, stress responses, and protein degradation. However, how these signals are regulated remains poorly understood. Both the SUMO-targeted ubiquitin E3 ligase (STUbL) RNF4 and the SUMO-specific isopeptidase SENP6 recognize poly-SUMO-2/3 chains through multiple SUMO-interacting motifs (SIMs). RNF4 contains four tandem SIMs within a short (~80 amino acids) region, whereas SENP6 possesses eight SIMs spanning a much larger (~500 amino acids) domain.

Our preliminary results show that overexpressing an RNF4 N-terminal fragment containing four tandem SIMs (wild type, WT), but not an inactive SIMs mutant (Mut), increases levels …

Post-Emption And The Mayoral Toolbox: Levers And Limits Of City Resistance To State Preemption, Quinton D. Lucas, Gavriel Schreiber

University of Chicago Law Review

States increasingly deploy aggressive preemption measures against disfavored localities. Scholars have raised the alarm, but cities’ subordinate legal status leaves them disempowered. To push back, municipal advocates need to thoroughly under- stand the complex bilateral relationship between cities and their states.

That is where I come in. As mayor of a progressive city in a conservative state, I swim in the hostile symbiosis that characterizes city-state relations. By drawing on real-life examples, closed-door conversations, and previously private documents, my coauthor and I demonstrate the potence of multipronged city power. We synthesize our stories into a thicker account of state motivation …
