Robustness Investigation, Detection, And Defense Of Deep Learning Models Against False Data Injection, Amirhossein Nazeri

All Dissertations

This dissertation addresses the critical challenge of adversarial robustness in deep learning systems, focusing on two fundamental domains: time-series prediction and object detection. As these AI systems become increasingly deployed in safety-critical applications from power grid management to autonomous vehicles their vulnerability to adversarial attacks poses significant risks to infrastructure and human safety.

The first contribution introduces a novel stealthy black-box False Data Injection (FDI) attack specifically designed for quasi-periodic time-series data. Unlike existing attacks that produce easily detectable anomalies, our method generates adversarial perturbations that preserve the underlying periodicity and statistical properties of the data, effectively bypassing traditional anomaly …

Robust Adaptive Rigid Body State And Mass Property Estimation Via Unscented Kalman Filter On Tse(3) With Process Noise Estimation, Herman Gunter

Doctoral Dissertations and Master's Theses

Mass property estimation, including mass, center of mass, and moment of inertia, is a crucial yet challenging problem in spacecraft autonomy and astrodynamics. Knowledge of mass properties of a spacecraft is essential for future astronautical missions, as changes in the mass properties of a spacecraft due to a shift in cargo distribution often require a careful and costly recalculation to ensure applied control inputs produce the desired results. As spacecraft missions grow in both duration and number, meeting the need for precise and accurate measurements becomes increasingly complex. Stochastic effects, such as angle and velocity random walks, along with persistent …

Discovery Of High-Performance Cathode Materials For Protonic Ceramic Fuel Cells, Liang Han

All Dissertations

Environmental pollution and rapid energy consumption have become common problems in global development and will continue to grow with the world population. PCFCs use proton-conducting ceramics as electrolytes, with low activation energy and high ionic conductivity at intermediate temperatures, enabling them to operate at intermediate-temperature conditions, which can effectively solve the problems of poor stability and high cost of exotic materials of traditional solid oxide fuel cells. However, as the operating temperature decreases, the electrocatalytic activity of the cathode decreases significantly, seriously affecting PCFC’s performance. Therefore, developing high-performance cathode material suitable for working under intermediate-temperature conditions has become the key …

Secure Control And Trust Evaluation Framework For Autonomous Transportation Systems, Grace Muriithi

All Dissertations

This dissertation advances the cybersecurity of hybrid tracked vehicles (HTVs) and ship power systems (SPSs) by developing innovative cyber-attack models and corresponding defence frameworks. First, we formulate stealthy false-data-injection attacks (FDIAs) on HTV energy-management systems as a partially observable Markov decision process (POMDP) solved via deep reinforcement learning. A novel sniffing-based reward function guides the attacker to covertly degrade battery capacity and energy efficiency, which we evaluate using custom stealth–impact metrics and a sliding-window anomaly detector (Isolation Forest with Dynamic Time Warping). Additionally, we model sophisticated control-layer attacks in HTVs, including reinforcement-learning-optimised replay attacks and denial-of-service (DoS) attacks targeting generator-speed …

How Was Rehab? A Follow-Up To A Randomized Effectiveness Control Trial Of A Brief Acceptance And Commitment Therapy Protocol For Inpatient Detoxification Patients, Alexander J. Twohy

Dissertations

Residential treatment for Substance Use Disorders (SUD) is a common treatment modality. However, the literature is sparse on modifiable predictors that affect change during the residential treatment stay. Acceptance and Commitment Therapy (ACT) has been shown to be an effective treatment for SUDs. Weststrate et al. (2023), in a randomized controlled effectiveness trial, compared ACT plus medication management to medication management during detoxification. The addition of ACT increased consumer satisfaction and ACT skills use, while decreasing psychological inflexibility and reducing withdrawal symptoms.

This study explored whether the brief ACT intervention had impacts during participants' subsequent residential stay. Forty out of …

Soil Carbon Storage And Its Relation To Abiotic And Biotic Factors In The Boise Foothills, Richie William Holder

Boise State University Theses and Dissertations

Terrestrial soil sequesters a significant amount of carbon (C), and changes to this pool can impact atmospheric CO2 concentrations and climate change. Thus, it is crucial to understand the drivers of the size of this pool. Changes in plant community composition in semi-arid ecosystems can impact soil C storage. However, little is known about the impact of plant functional type on the quantity and distribution of soil C on a landscape scale relevant to ecosystem management. I conducted a study in the City of Boise’s Open Space Reserves located north of Boise, Idaho to evaluate how plant functional type affects …

Unraveling Snow And Rain Contributions To Streamflow Through A Methodological Investigation On Cold And Warm Season End-Members, Rachel Grena

Boise State University Theses and Dissertations

Water supply and demand are encountering unique challenges in the western United States as climate change impacts the availability of water resources. Much of the west relies on high mountain snowpack to maintain consistent streamflow throughout the dry, warm season months. Temperatures often rise above freezing in the cold season, diminishing the snowpack size, and altering the timing of snowmelt. As droughts become more frequent, water managers are increasingly concerned about the risk of reduced summer streamflow. To understand changing hydrologic patterns, this study utilizes phase changes in precipitation, specifically the distinction between cold and warm season precipitation, and their …

Social And Economic Gradients Of Resource Transfer Behavior In Gorongosa, Mozambique, Karl J. Mertens

Boise State University Theses and Dissertations

Why do people who experience the same environmental and social conditions vary so much in their resource transfer behavior? This dissertation addresses that question through examination of behavioral variation in subsistence horticulturalists in the dry tropical forest bufer conservation area of Gorongosa National Park in Mozambique. In this region of moderate and acute food shortages at both household and regional levels, individuals face similar challenges of addressing social and resource uncertainty yet respond with marked behavioral variation that cannot be explained solely by diferences in wealth, kinship, or reciprocity patterns.

Using a Behavioral Reaction Norms (Dingemanse et al., 2010) (BRN) …

Aging Effect On Effective Connectivity Within The Prefrontal-Motor Network And Postural-Related Muscle Responses During Dual-Task Paradigms, Jiahao Pan

Boise State University Theses and Dissertations

Falls are a significant global public issue for older adults, leading to severe health and social impacts. To understand the underlying mechanism of increased fall risk with aging, loss of postural automaticity has been suggested as increased prefrontal cortex and motor cortices activation, as well as worse balance performance in response to the secondary cognitive task. However, the interaction within these cortical regions and its effects on postural-related muscle responses are poorly understood. This dissertation investigated age-related changes in effective connectivity within the prefrontal-motor network, postural related lower limb muscle response, and biomechanical characteristics in response to the secondary cognitive …

Considerations For Developing Dna-Templated Dye-Aggregate Systems, Simon Kristopher Roy

Boise State University Theses and Dissertations

Molecular excitons have been the subject of significant research interest for nearly 100 years. Molecular excitons arise when conjugated organic molecules (dyes) are excited such that the resulting excitation is delocalized over multiple dyes in a wavelike manner. The shared excited states that allow the excitation energy to hop between molecules is of particular interest for applications that can make use of the wavelike properties of excitons, including applications in quantum information science. A key challenge for developing materials for these advanced applications is to overcome the knowledge gaps associated with precisely templating dyes with spatial control of their aggregation, …

Biojardineras In Monteverde: A Mixed Method Approach To Examine Greywater Treatment, Elyssa Allen, Jackson Anderson, Brayden Dostal, Alan Hernandez, Kacy Moe, Facundo Pereya-Kluser

Monteverde Institute: Tropical Ecology and Conservation

Rural and semi-rural regions around the globe often struggle with inadequate wastewater treatment infrastructure, thereby negatively impacting the public and environmental health of the region. Due to its rural nature and current infrastructure, the Monteverde Zone (MVZ) in Costa Rica lacks a centralized wastewater system, with many homes relying on septic tanks for wastewater treatment. To prevent overloaded flows to septic tanks, greywater from kitchens, laundry, showers, and sinks is often discharged separately to the environment with no treatment. This pollutes the surrounding water bodies and streets with pathogens, soap, excess nutrients, as well as fats, oils, and grease (FOG). …

The Lived Experiences Of Fathers With Postpartum Depression: A Qualitative Study, Rachael Elizabeth Schmitz

Nursing and Health Sciences

Background:

Although parents may joyfully anticipate the birth of a child, it's impossible for them to know ahead of time just how profoundly their lives will change. Postpartum depression (PPD) can result. While there is a substantial body of research regarding maternal PPD, paternal PPD has received far less attention and is neither adequately understood nor diagnosed. This is exacerbated by outdated but persistent sociocultural masculinity norms and the stigmas around mental health issues.

Purpose:

This study sought to explore the lived experiences of new fathers with PPD in order to provide greater insight into their experiences.

Methods:

This qualitative …

Some of the main obstacles reported were not properly training staff and keeping patients from sharing their thoughts on this subject.

The main objective of the doctoral project was to test …

Parenting For Wellness: Positive Parenting Factors As Predictors Of College Student Physical Health, Mental Health, And Social Connectedness Through The Lens Of Self-Determination Theory, Mary E. Lamkin

Dissertations

Research suggests that the transition to college can impact college student well-being across the domains of physical health, mental health, and social connectedness (Frech, 2012; Pittman & Richmond, 2008; Xiao et al., 2017). As parents are more heavily connected to their college-aged students when compared to years before cell phones and social media, they likely continue to play a significant role in their child’s well-being, even while they are in college (Wartman & Savage, 2008). Therefore, the aim of this dissertation was to investigate positive parenting behaviors as predictors of wellness in college-aged participants using Self Determination Theory (Ryan & …

Coyote (Canis Latrans) And Non-Target Wildlife Responses To Livestock Guardian Dogs At Sheep Grazing Sites On The California Central Coast, Tricia T. Nguyen
