Bypassing Modern Cpu Protections With Function-Oriented Programming, Logan Stratton

Masters Theses & Doctoral Dissertations

Over the years, code reuse attacks such as return-oriented programming (ROP) and jump-oriented programming (JOP) have been a primary target to gain execution on a system via buffer overflow, memory corruption, and code flow hijacking vulnerabilities. However, new CPU-level protections have introduced a variety of hurdles. ARM has designed the “Pointer Authentication” and “Branch Target Identification” mechanisms to handle the authentication of memory addresses and pointers, and Intel has followed through with its Shadow Stack and Indirect Branch Targeting mechanisms, otherwise known as Control-Flow Enforcement Technology. As intended, these protections make it nearly impossible to utilize regular code reuse methods …

Ai-Based Bridge And Road Inspection Framework Using Drones, Hovannes Kulhandjian

Mineta Transportation Institute

There are over 590,000 bridges dispersed across the roadway network that stretches across the United States alone. Each bridge with a length of 20 feet or greater must be inspected at least once every 24 months, according to the Federal Highway Act (FHWA) of 1968. This research developed an artificial intelligence (AI)-based framework for bridge and road inspection using drones with multiple sensors collecting capabilities. It is not sufficient to conduct inspections of bridges and roads using cameras alone, so the research team utilized an infrared (IR) camera along with a high-resolution optical camera. In many instances, the IR camera …

Sentiment And Accruals Earnings Management: Does Governance And Regulatory Environment Matter?, Kakul Modani, Saumya Ranjan Dash, Mehul Raithatha, Robert Brooks

American Business Review

This paper examines the implications of firm-level governance mechanisms and the regulatory environment on the relationship between investor sentiment and accrual-based earnings management. Our findings confirm the positive impact of sentiment on earnings management through accruals. Our results confirm that in the presence of a stringent regulatory environment, the likelihood of abnormal accruals following a positive sentiment environment is low. We document that a stringent regulatory environment reduces the likelihood of abnormal accruals following a positive sentiment environment. Results further confirm that improved governance characteristics like larger board, increased board independence, and stringent related party transaction norms help to monitor …

Hedging Around A Ceo Change: Further Evidence From The Oil And Gas Industry, Zahid Iqbal, Shekar Shetty

Information Sharing In A Green Supply Chain With A Common Retailer, Abdul Quadir, Alok Raj

American Business Review

In the paper, we analyze the problem of information sharing in a green supply chain with two competing manufacturers selling environmentally friendly substitutable products in markets through a common retailer. We develop a game-theoretic framework of a network supply chain structure. The study shows that (a) the manufacturer is better off while the retailer is worse off when the retailer shares his private information with the manufacturer; (b) the equilibrium greening levels are the highest when both the manufacturers are informed; (c) under intense competition, the retailer has an incentive to share the information with the manufacturer; (d) the equilibrium …

Environmental Sustainability Strategy, Creativity, Innovation And Organizational Performance: The Role Of Green Human Resource Management, Jessica R. L Good, Parbudyal Singh, Souha Ezzedeen

American Business Review

This paper provides a theoretical explanation for the “black box” between “going green” and organizational performance and links individual-level behaviors with organizational-level outcomes. We argue that the adoption of an environmental sustainability strategy and high involvement green human resources management practices will have the intended impact of increasing employee green creativity and the unintended impact of increasing employee general creativity. As well, we suggest that employee green values moderate these relationships. Furthermore, the positive effects on employee creativity (green and general) are theorized to increase organizational innovation, which positively impacts organizational performance. This paper extends the research by providing a …

Meta-Analysis Of Insulated Concrete Wall Panel Design Methods For Shear And Flexure Behavior, Maryam Al-Bayati

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Insulated Concrete wall panels have been designed and constructed since the early 1950s with various shear ties, dimensions, and methods; nonetheless, thermal bridging and rational design are still a concern. Many companies have recently developed plastic connectors that have gradually replaced solid concrete sections and steel connectors due to their superior thermal efficiency and strength. However, there is no generally accepted method for predicting the behavior of sandwich wall panels in structural engineering practice or codes, but many methods have been used since the early 1920. This study aims to evaluate the accuracy of current methods for predicting the flexural …

Uv Dynamics Of Different Ring Molecules Studied By Ultrafast Electron Diffraction, Sajib Kumar Saha

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

Understanding natural light-induced phenomena requires a direct viewing of atomic motion during structural evolution, which, in turn, facilitates controlling and manipulating these light-induced processes. Ultrafast Electron Diffraction (UED) is a structure-sensitive technique that can probe electronic and nuclear dynamics at sub-angstrom spatial and femtosecond time scales. UED has become a vital tool for studying photo-induced molecular dynamics and underlying science. Organic ring systems are prevalent in biology, materials, and pharmaceuticals. Their synthesis and transformation are fundamental in synthetic chemistry, influencing various fields. We used UV photons to photo-excite different cyclic molecules and investigated their photo-dynamics using gas phase UED. The …

A Generalized Machine Learning-Based Classifier Considering Cost-Effective Features For Automated Fault Detection And Diagnosis (Afdd) Of Packaged Rooftop Units, Md Rasel Uddin

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

Packaged rooftop units (RTUs) are widely used for space conditioning in commercial buildings and manufacturing facilities. The typical soft faults related to RTUs degrade the system's performance in terms of cooling capacity, power consumption, and Coefficient of Performance (COP), detrimentally affecting both the equipment and energy consumption and the environment. Previous research in soft fault detection for rooftop units lacked classifier validation using lab and field data, developing a generalizable algorithm, and analyzing its performance across varying fault intensities.

Using a simulated data library for multiple rooftop units, this study proposes a machine-learning classifier with a reduced set of 9 …

Department of Paediatrics and Child Health

Next-generation sequencing technology has revolutionised pathogen surveillance over the last two decades. However, the benefits are not equitably distributed, with developing countries lagging far behind in acquiring the required technology and analytical capacity. Recent declines in the cost associated with sequencing-equipment and running consumables have created an opportunity for broader adoption. During the COVID-19 pandemic, rapid diagnostics development and DNA sequencing revolutionised the ability to diagnose and sequence SARS-CoV-2 rapidly. Socioeconomic inequalities substantially impact the ability to sequence SARS-CoV-2 strains and undermine a developing country's pandemic preparedness. Low- and middle-income countries face additional challenges in establishing, maintaining and expanding genomic …

Effect Of Type And Quantity Of Inherent Alkali Cations On Alkali-Silica Reaction, Pengfei Ma, Jiaoli Li, Jincheng Bai, Ying Zhuo, Lingyu Chi, Yanping Zhu, Zhenhua Shi, Hongyan Ma, Genda Chen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, the macroscopical expansion induced by alkali-silica reaction (ASR) and its corresponding ASR products are investigated using ordinary Portland cement (OPC) mortar specimens with a gradient of boosted alkalis. Experimental results show that the expansion increases with the concentration of inherent alkalis. Sodium-boosted samples expand approximately three times as much as potassium-boosted samples. ASR gels that are present in aggregate veins are calcium-free and amorphous; the atomic ratios of ASR gels are nearly independent of the type and quantity of alkali cations. Aggregate ASR gel exudation occurs in high (≥2.5 %) sodium cases and produces potential Na-shlykovite. Crystalline …

The State-Led Platformisation Of Financial Services: Frictionless Ecosystems And An Expansive Logic Of "Smartness" In Singapore, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This article explores the role of the state in driving the platformisation of industry, and in doing so offers a counterpoint to scholarship that focusses on the exploitative effects of private sector-led platformisation. That scholarship views platformisation as the latest incarnation of neoliberal urbanism, with the profit-maximising tendencies of the private sector driving the proliferation of platforms throughout everyday life. Notwith- standing, there remains a need to consider alternative models of platformisation. Drawing on 31 interviews with architects of Singapore’s Smart Nation initiative, we consider the state-led platformisation of financial services. We argue that state-led platformisation can open up marketplaces …

The Illusory Infrastructure Of Ink: Machinic Bodies And Epidermic Affects In Singapore, Orlando Woods

Research Collection College of Integrative Studies

This paper advances recent theorisations of the body-as-infrastructure by exploring the premise that there are multiple bodily infrastructures at play at any one time. It focusses on three infrastructural formations – the body, the skin that encases the body, and tattoos as visual inscriptions on the skin – that jostle against each other for representational primacy. The layering of infrastructure-upon-infrastructure leads to understandings of the self that exist in a state of tension with societal norms and the illusions of self-representation. Indeed, it is the intersecting gazes of society and the self that cause these infrastructures to become disaggregated, and …

After Great Pain: The Uses Of Religious Folklore In Kenji Mizoguchi’S Sansho The Bailiff (Jp 1954) And Kaneto Shindo’S Onibaba (Jp 1964), Teng-Kuan Ng

Research Collection College of Integrative Studies

This article studies the adaptations and applications of religious folklore in two mas-terworks of Japanese cinema: Kenji Mizoguchi’s Sansho Dayu (Sansho the Bailiff, JP 1954) and Kaneto Shindo’s Onibaba (JP 1964). While academic approaches will often draw a strict line between narrative genres and discursive forms, these films, I argue, draw creatively from Japanese tradition for both critical and constructive purposes in the postwar context. Besides mounting trenchant criticisms of Japan’s erstwhile militaristic violence and imperial ambitions, both filmmakers present their respective female protagonists as models for spiritual and sociocultural transformation in the face of anomie. Embodying humanistic compassion on …

Enhancing Classification Of Energy Meters With Limited Labels Using A Semi-Supervised Generative Model, Chun Fu, Hussain Kazmi, Matias Quintana, Clayton Miller

Research Collection College of Integrative Studies

In the energy domain, the classification of power meters has become an increasingly significant area of interest, such as appliance identification and characteristics prediction, enabling targeted and efficient energy management. However, the limited availability of labeled data for power meters and the inconsistencies in labeling and naming conventions have constrained the potential of metadata for further application. This study aims to bridge the gap by employing semi-supervised Generative Adversarial Networks (SGAN) to classify 1805 power meters distributed globally. This approach explores and assesses the advantages of incorporating unlabeled power meter data into the learning process. A comparative analysis is performed …
