Towards Context-Aware Traffic Classification Via Time-Wavelet Fusion Network, Ziming Zhao, Zhuoxue Song, Xiaofei Xie, Zhaoxuan Li, Jiongchi Yu, Fan Terry Zhang, Tingting Li

Research Collection School Of Computing and Information Systems

Encrypted traffic classification occupies a significant role in cybersecurity and network management. The existing encrypted traffic classification technology mostly relies on intra-flow semantics for extracting features. However, considering that some attack behaviors inherently have similar patterns to legitimate behaviors, and powerful adversaries could simulate benign users to conceal their attack intentions, intra-flow features may be similar between different categories. In this paper, we propose TrafficScope, a time-wavelet fusion network based on Transformer to enhance the performance of encrypted traffic classification. Specifically, in addition to using intra-flow semantics, TrafficScope also extracts contextual information to construct more comprehensive representations. Moreover, to cope …

Tetd: Trusted Execution In Trust Domains, Zhanbo Wang, Jiaxin Zhan, Xuhua Ding, Fengwei Zhang, Ning Hu

Research Collection School Of Computing and Information Systems

Intel TDX empowers cloud service providers to construct confidential virtual machines called trust domains (TDs) on x86 platforms. Similar to its counterparts from AMD and Arm, TDX's hardware based protection over integrity and secrecy of virtual machine memory and vCPU states inevitably hinders legitimate virtual machine management such as introspection. At the presence of compromised high-privileged software (e.g., the guest kernel), neither the cloud service provider nor the TD owner can securely carry out a task within the TD. To tackle this problem, we propose TETD, an in-TD trusted execution technique without trusting any TD system software. Our design does …

Oblivious Digital Tokens, Mihael Liskij, Xuhua Ding, Gene Tsudik, David A. Basin

Research Collection School Of Computing and Information Systems

A computing device typically identifies itself by exhibiting unique measurable behavior or by proving its knowledge of a secret. In both cases, the identifying device must reveal information to a verifier. Considerable research has focused on protecting identifying entities (provers) and reducing the amount of leaked data. However, little has been done to conceal the fact that the verification occurred.We show how this problem naturally arises in the context of digital emblems, which were recently proposed by the International Committee of the Red Cross to protect digital resources during cyber-conflicts. To address this new and important open problem, we define …

Practical Keyword Private Information Retrieval From Key-To-Index Mappings, Meng Hao, Weiran Liu, Liqiang Peng, Cong Zhang, Pengfei Wu, Lei Zhang, Hongwei Li, Deng, Robert H.

Research Collection School Of Computing and Information Systems

This paper introduces practical schemes for keyword Private Information Retrieval (keyword PIR), enabling private queries on public databases using keywords. Unlike standard indexbased PIR, keyword PIR presents greater challenges, since the query’s position within the database is unknown and the domain of keywords is vast. Our key insight is to construct an efficient and compact key-to-index mapping, thereby reducing the keyword PIR problem to standard PIR. To achieve this, we propose three constructions incorporating several new techniques. The high-level approach involves (1) encoding the server’s key-value database into an indexable database with a key-to-index mapping and (2) invoking standard PIR …

Mpo: Multilingual Safety Alignment Via Reward Gap Optimization, Weixiang Zhao, Yulin Hu, Yang Deng, Tongtong Wu, Wenxuan Zhang, Jiahe Guo, An Zhang, Yanyan Zhao, Bing Qin, Tat-Seng Chua, Ting Liu

Research Collection School Of Computing and Information Systems

Large language models (LLMs) have become increasingly central to AI applications worldwide, necessitating robust multilingual safety alignment to ensure secure deployment across diverse linguistic contexts. Existing preference learning methods for safety alignment, such as RLHF and DPO, are primarily monolingual and struggle with noisy multilingual data. To address these limitations, we introduce Multilingual reward gaP Optimization (MPO), a novel approach that leverages the well-aligned safety capabilities of the dominant language (e.g., English) to improve safety alignment across multiple languages. MPO directly minimizes the reward gap difference between the dominant language and target languages, effectively transferring safety capabilities while preserving the …

Think Both Ways: Teacher-Student Bidirectional Reasoning Enhances Mcq Generation And Distractor Quality, Yimiao Qiu, Yang Deng, Quanming Yao, Zhimeng Zhang, Zhiang Dong, Chang Yao, Jingyuan Chen

Research Collection School Of Computing and Information Systems

Generating high-quality Multiple Choice Questions (MCQs) remains challenging for educational tools due to the need for contextual relevance and plausible distractors. Existing methods still struggle with these dual requirements, leading to questions that lack depth and distractors that are either too obvious or irrelevant. In this paper, we propose BiFlow, a novel framework that integrates bidirectional reasoning perspectives: teacher reasoning generates contextually relevant questions and plausible distractors, while student reasoning evaluates question clarity and the misleading nature of the distractors. To further enhance reasoning, we introduce PathFinder, a mechanism that employs breadth-first search and Chainof-Thought (CoT) strategies to explore diverse …

Pricing The Unknown: An Analysis Of Expected Value Of Young Horses And Price-Determining Factors, Rupasri Sura

Graduate Theses and Dissertations

From a seller’s point of view in a market, it is crucial to plan the pricing strategies based on perceptions of buyer preferences and their willingness to purchase to ensure market success in selling and pricing. Applying this to the equine industry, this paper studies the factors determining the price of young horses (age ≤ 2 years) in digital auction platforms. Using data from Professional Horse Services, LLC (2012–2023), a Heckman’s two-step approach was employed, which involves a probit model as the first step and a hedonic price model as the second, aiming to correct for sample selection bias in …

Examining Shock Wave Flow Past The Brim Of A Helmet Using Schlieren Imaging, Cody Thomas, Catherine E. Johnson

Mining Engineering Faculty Research & Creative Works

Increasing the protection a helmet provides the user from shock waves can help reduce the prevalence of blast induced traumatic brain injury (bTBI). Previous research has shown that air enters and gets trapped in the helmet-head cavity and can increase the overpressure experienced by the wearer. The brim design of the helmet has yet to be studied to understand how shock waves flow into the helmet. By studying a variety of brims, it is possible that the design can be modified to minimize shock wave flow into the helmet. This paper investigated a shock wave impacting interior and exterior facing …

Using Interpersonal Motives To Identify Latent Profiles Of Borderline Personality Pathology: Implications For An Overcontrolled Style Of Bpd, Regina Schreiber

Graduate Theses and Dissertations

Borderline personality disorder (BPD) is conceptualized as a disorder of undercontrol (i.e., behaviorally impulsive, emotionally expressive), with affective, interpersonal, and identity instability. BPD related impairment is high, yet diagnostic accuracy remains a problem for individuals who present with greater overcontrol (i.e., behavioral inhibition, expressive suppression), which occurs in some BPD subtypes. The current study used ecological momentary assessment (EMA) to expand on prior research by identifying latent profiles based on interpersonal motives for agency and relatedness, desire for predictability, perceived dependency, and self-efficacy in a sample of people with elevated BPD features (n = 136). Individual differences in overcontrol, undercontrol, …

End Times: American Mortality, Death Materiality, And Social Death In The 1990s, Jordan A. Savage

Graduate Theses and Dissertations

The United States in the 1990s was marked by pervasive representations of death in popular culture. As death imagery became increasingly visible in entertainment, there was a growing detachment from the embodied, biological realities of death, a tension intensified by the ongoing AIDS crisis. This project explores how death is politicized and how decisions about who lives and dies are shaped by power. I draw on a constellation of theoretical frameworks that collectively illuminate the operations of state-sanctioned death and social abandonment. These include Michel Foucault’s concept of biopolitics, which examines the management of life by state power; Giorgio Agamben’s …

Cultural Vibrations: Student Power, International Exchange, And Black America In Mai 1968, Noah Micheal Roberts

Graduate Theses and Dissertations

Abstract This thesis examines the prominence of Black Americans in the 68’ student movement in France. May 68’ incorporated a diverse and global network of social movements and political organizations, and had a notable connection to the American student movement. Black Americans had formed a large expatriate community in France which overlapped with many of the transnational connections forged by the student movements of 68’. This community was extremely notable in the French public sphere for popular works of literature and music, but its political contributions have been minimized or understudied. By utilizing student accounts, state and organizational records, and …

Lifetime Stressor Exposure, Race And Ethnicity, And Habitual Stress Processes: An Evaluation Of Repetitive Negative Thinking And Hair Cortisol Concentration, Harrison Dickens

Graduate Theses and Dissertations

Habitual stress processes are thought to influence acute stress reactivity and stress-related disease. Habitual stress processes have been shown to adapt in response to stressor exposure experienced across the lifespan. The current study seeks to explore whether two habitual stress processes, hypothalamic-pituitary-adrenal (HPA) axis activity and repetitive negative thinking (RNT), were associated with lifetime stressor exposure (self-reported and objective neighborhood-level stressors). Additionally, the current study attempts to quantify how this process may be moderated by race and ethnicity. Participants (N = 134, Mage = 18 [SDage= 1.69], 56.7% female) consisting of White (N = 52), Black (N = 37 ), …

The Effects Of Background Child-Directed And Adult-Directed Singing On Reading Comprehension Performance, Agnes Yeboah Amfo-Adu

Graduate Theses and Dissertations

Although music features in speech, such as those found in child-directed speech and song, are known to enhance language processing, the underlying mechanism of this benefit remains unclear. Prior research has primarily compared verbal materials presented in a musical, child-directed style to those in a less musical, adult-directed style, leaving it uncertain whether the benefit stems from the music style of verbal presentation or mere exposure to musical features. This study examined whether the language benefits of child-directed input persist when it is presented as background auditory stimuli rather than the primary focus of cognitive tasks. Experiment 1 found that …

An Examination Of Legal Status, Law Enforcement Perception, And Crime Victimization And Reporting Among Hispanic Immigrants, Guadalupe C. Cabrera

Electronic Theses and Dissertations

This study relied on in-depth interviews with naturalized citizens and lawful permanent resident Hispanic immigrants to explore their perceptions of law enforcement and experiences with crime victimization and reporting. Past literature has explained that the absence of legal status may deter crime reporting. We added to this body of work by investigating relationships among legal status, trust, and reporting behaviors. This study finds that direct experiences with law enforcement and acquired knowledge may be a better indicator of law enforcement trust and crime reporting compared to legal status. While most participants expressed trust in law enforcement, others felt neutral due …

Empathetic Differentiated Instruction In Deaf Education: Examining Influencing Factors And Experienced Educator Practices, Laura A. Blackburn

STEMPS Master's Level Projects and Papers

This mixed-methods study investigated how experienced K–12 deaf educators implement empathetic, differentiated instruction (EDI) to support the academic and linguistic needs of deaf students who use American Sign Language (ASL) as their language of learning. Guided by Tracey and Baaki’s instructional design empathy model and grounded in constructivism, the study explored how teachers navigated the tension between standardized, English (sound-based) curriculum demands and the need to make instructional decisions aligned with signed language modalities and responsive to students’ real-time learning needs.

A custom electronic survey was distributed to a national sample of experienced educators, with 19 respondents completing Likert-scale items, …

Comparison Of Nutrient Concentrations And Primary Production Indicators Across Plume Fronts, Taylor Dishon

Electronic Theses and Dissertations

Coastal buoyant plumes carry low-salinity waters containing particulate and dissolved terrestrial materials with an abundance of nutrients into the coastal ocean, including inorganic nitrogen and phosphorous. Plume fronts act as transport barriers created from the convergence of a fresher plume with an older, saltier plume or with ambient waters, leading to potential accumulation of phytoplankton and nutrients. This accumulation creates an optimal environment for primary production. The primary goals of this study were: to investigate the distribution of and potential relationships between nutrient concentrations and chlorophyll a across plume fronts of the Winyah Bay River Plume, and examine potential relationships …

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

During the Last Glacial Maximum (LGM), the Great Plains in Nebraska consisted of wooded parklands and grasslands, whereas spruce (Picea) forests, parklands, and steppe grasslands dominated east of the Missouri River. I analyzed bulk carbon (δ¹³C), oxygen (δ¹⁸O), and strontium (⁸⁷Sr/⁸⁶Sr) isotopes from tooth enamel in isolated mammoth (Mammuthus) molars to compare diet and movement patterns in two late Pleistocene assemblages: one in Nebraska (n = 24), and one in western Iowa and Missouri (n = 17). Furthermore, I identified a morphometric subset of molars as …

Online Prediction Of Streaming Data, Aleena Chanda

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

We present two new approaches for point prediction with streaming data based on a) the Count-Min sketch and b) Gaussian Process Priors with random bias. The methods are intended for the most general case where no true model can be usefully formulated for the data stream. In statistical contexts, this is often called the M open problem class. For the Count Min Sketch method we show that the predicted distribution function ^F converges to F under the assumption that the data consists of i.i.d samples from a fixed distribution function F. To implement the Gaussian Process Prior methods, we used …

Modifying Italian Consonants In The Voice Studio: An Exploratory Sequential Mixed Methods Study, Elisa Ramon

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The body of lyric diction literature, particularly on Italian, has grown substantially in the second half of the twentieth century. Lyric diction courses are now a required part of many voice programs across the United States. The widespread use of International Phonetic Alphabet (IPA) transcriptions and transcription rules has significantly contributed to the field. However, relatively few sources focus on the pedagogical strategies needed to teach and modify Italian consonants effectively.

This two-phase exploratory sequential mixed methods study identifies the features of Italian consonants that differentiate the lyric diction of novice singers from that of native speakers. It also proposes …

Soft Infrastructure And The Location Choice Of Multinational Firms:Evidence From Japanese Investment In The United States In The 1980s, Shuichiro Nishioka, Eric Olson, Haoyu Wang

Economics Faculty Working Papers Series

We examine whether culture-specific educational infrastructure influenced the location decisions of multinational enterprises by analyzing Japanese foreign direct investment (FDI) in the United States during the 1980s. Using the quasi-natural experiment of politically-driven Japanese FDI following Reagan-era trade tensions, we test whether pre-existing Japanese Studies programs in U.S. universities predict subsequent Japanese investment across 722 commuting zones. We find that zones with Japanese Studies programs in 1980 were 21-29% more likely to receive new Japanese manufacturing investment by 1992, controlling for traditional determinants likemanufacturing infrastructure, agglomeration, and market access. Our results suggest that "soft infrastructure"—culture-specific human capital pipelines—represents an overlooked …
