Archaeologies Of Roads, Tuna Kalaycı

Digital Press Books

What happens if we think of roads not only as a static archaeological object but as a dynamic and complex phenomenon?

Inspired by this question, “Archaeologies of Roads” brings together various studies spanning diverse landscapes and epochs. The central premise of the book is to reveal the complexity of the road, be it a modern or an ancient one. The starting point is that the road is not only a container for action but also the action itself; roads are perpetual works in progress, continually shaping and being shaped by the world around them.

Authors contribute with road studies from …

Catching Elusive Depression Via Facial Micro-Expression Recognition, Xiaohui Chen, Tony Tie (T.) Luo

Computer Science Faculty Research & Creative Works

Depression is a common mental health disorder that can cause consequential symptoms with continuously depressed mood that leads to emotional distress. One category of depression is Concealed Depression, where patients intentionally or unintentionally hide their genuine emotions through exterior optimism, thereby complicating and delaying diagnosis and treatment and leading to unexpected suicides. In this article, we propose to diagnose concealed depression by using facial micro-expressions (FMEs) to detect and recognize underlying true emotions. However, the extremely low intensity and subtle nature of FMEs make their recognition a tough task. We propose a facial landmark-based Region-of-Interest (ROI) approach to address the …

Artificial Intelligence And Urban Operations, Anthony King

Journal of Strategic Security

It is widely believed that AI is about to revolutionise military operations. Many scholars have claimed that AI-enabled lethal autonomous weapons, especially drone swarms, are about to take over the battlefield. This article assesses the merits of those claims in relation to urban operations. Examining the cases of the Joint Special Operations Command in Baghdad in 2004-08 and the IDF's Operation Guardian of the Walls in 2021, it argues that AI will primarily be for military intelligence and targeting, rather than lethal autonomy.

Comparison Of A Patient-Specific Computed Tomography Organ Dose Software With Commercial Phantom-Based Tools, Bindu P. Bhat

Master's Theses (2009 -)

Computed Tomography imaging is an important diagnostic tool but carries some risk due to radiation dose used to form the image. Currently, CT scanners report a measure of radiation dose for each scan that reflects the radiation emitted by the scanner, not the radiation dose absorbed by the patient. The radiation dose absorbed by organs, known as organ dose, is a more relevant metric that is important for risk assessment and CT protocol optimization. Tools for rapid organ-dose estimation are available but are limited to using general patient models. These publicly available tools are unable to model patient-specific anatomy and …

Striving To Increase Bipoc Family Participation In Early Childhood Family Education, Ayuko Boomer

School of Education and Leadership Student Capstone Theses and Dissertations

Boomer, A. U. (2023). Striving to Increase BIPOC Family Participation in Early Childhood Family Education. Early Childhood Family Education (ECFE) is a public education program designed and available for all parents and families in Minnesota. Despite these intentions, many Black, Indigenous, and People of Color (BIPOC) families remain unaware of ECFE's existence and its significance. The purpose of this study is to understand the current methodologies of parent education outreach and collaboration with other programs, in particular, BIPOC communities, and explore and process what efforts have been made to increase BIPOC participation in traditional ECFE parent education group classes (non-affinity …

Risk-Seeking Governance, Brian J. Broughman, Matthew T. Wansley -- Assoc. Professor Of Law

Vanderbilt Law Review

Venture capitalists (“VCs”) are increasingly abandoning their traditional role as monitors of their portfolio companies. They are giving startup founders more equity and control and promising not to replace them with outside executives. At the same time, startups are taking unprecedented risks—defying regulators, scaling in unsustainable ways, and racking up billion-dollar losses. These trends raise doubts about the dominant model of VC behavior, which claims that VCs actively monitor startups to reduce the risk of moral hazard and adverse selection. We propose a new theory in which VCs use their role in corporate governance to persuade risk-averse founders to pursue …

Place For Sociohydrology In Sustainable And Climate-Resilient Agriculture: Review And Ways Forward, Soham Adla, Mohammad Faiz Alam, Melissa Haeffner, Murugesu Sivapalan

Environmental Science and Management Faculty Publications and Presentations

Given the increasing demand for high-quality food and protein, global food security remains a challenge, particularly in the face of global change. However, since agriculture, food and water security are inextricably linked, they need to be examined via an interdisciplinary lens. Sociohydrology was introduced from a post-positivist perspective to explore and describe the bidirectional feedbacks and dynamics between human and water systems. This review situates sociohydrology in the agricultural domain, highlighting its contributions in explaining the unintended consequences of water management interventions, addressing climate change impacts due to/on agriculture and incorporating human behaviour into the description of agricultural water systems. …

Reduced Bias User Preference Methods For Determining The Pareto-Optimal Solution Point, Dylan Thomas Johnson

Master's Theses (2009 -)

Engineering design is filled with tradeoffs between competing objectives such as performance, mass, cost, and schedule. A designer must navigate these complex multi-objective problems and deliver the right solution for their application. Multi-objective optimization techniques are powerful and widely used; however, a key drawback to these techniques is that they often output a set of equivalent solutions called the Pareto Front. The designer must perform an additional multi-objective down selection on the Pareto Front to determine a single Pareto-optimal solution point for their design. Existing Pareto Front processing techniques either use traditional infinitely adjustable weights, which can yield results that …

Long-Term Assessment Of Skeletal And Dental Asymmetry After Conventional And Mini-Screw Assisted Rapid Palatal Expansion, Brett Barton

Developing Continuous Predictive Controls For Ankle Angle And Moment Across Multiple Mobility Tasks, John Eganhouse

Master's Theses (2009 -)

This thesis aimed to create a predictive model for controlling lower limb prostheses, using electrical activity from muscles in the residual limb to predict ankle angle and moment across mobility tasks including level ground walking, stair ascent, and descent (LW, SA, and SD). In aim 1, kinematic and kinetic ankle data, were used together with electromyographic (EMG) signals obtained from six healthy ambulators to train a nonlinear autoregressive (NARX) model to predict ankle angle and moment. Networks were trained with a delay of 58.33 ms, using a 120 ms sampling window and tested for their ability to predict ankle angle …

Employing Thermal Imagery From Small Unmanned Aerial Systems To Model The Energy Balance Of Urban Runoff, Gregory M. Dieter

Master's Theses (2009 -)

The hydrologic urban heat island occurs when thermally polluted stormwater runoff is exported from hot urban centers to fragile downstream ecosystems. Mitigating runoff with higher temperatures requires an understanding of the relationship between land surface temperatures (LST) and stormwater runoff; however, LST is difficult to define due to the complexity of heterogenous urban catchments. Therefore, this thesis combines in-situ monitoring with thermal imaging via small unmanned aerial systems (sUAS) to understand how urban catchment heterogeneity influences runoff temperature. Based upon this data, a framework for modeling heat flux in stormwater runoff using sUAS LST datasets is presented. Monitoring was conducted …

Multivariable State Feedback Pid Control With Eigenvalue Assignment Via Linear Matrix Inequalities, Timothy Alexander Goodwin

Master's Theses (2009 -)

Proportional Integral Derivative control is the most dominant control technique used in industrial applications. Multivariable systems typically have multiple inputs and outputs which means the number of individual PID controllers and gains to be increased. The tuning of these systems to meet specific performance criteria would be impractical in these situations. The transient performance of a system can be modeled through the locations of its poles and zeros and through pole placement, we can mold the response to meet certain criteria. Linear Matrix Inequalities is an efficient way to solve this pole placement problem through the use of Regional Eigenvalue …

Faithful Is The Word: Forging A Pastoral Mentality Based On An Analysis Of The Phrase “Pistos Ho Logos” And Its Effectiveness When Applied To Pastoral Succession, Israel Sotolongo

Doctor of Ministry (DMin)

The aim of this thesis is to develop a biblically grounded resource that will prepare incoming pastors who will succeed retiring pastors of local churches. Studies show that most church succession attempts are not deemed successful, which is concerning since, over the next ten to twenty years, the American church will experience the largest wave of retiring pastors it has ever seen. This work addressed two learning gaps, as little exists in the form of resources directed primarily at incoming pastors and research on the clause Pistos ho Logos. Therefore, the primary research questions were “What are the meaning and …

Flujos De Servicios Ecosistémicos En Un Área Marina Protegida Del Atlántico Sur: Perspectivas Desde El Análisis De La Teoría De Redes, Mitch Porter

Independent Study Project (ISP) Collection

En cuestiones de gestión de áreas protegidas, los servicios ecosistémicos se tienen cada vez más en cuenta junto con la conservación de la biodiversidad. Sin embargo, las decisiones que se toman sobre la conservación de los servicios ecosistémicos no suelen incluir los posibles efectos en cascada de la pérdida de biodiversidad sobre la provisión de servicios. Los conocimientos de la teoría de redes y los estudios de robustez pueden proporcionar una metodología para evaluar la vulnerabilidad de estos servicios frente la estructura trófica de los ecosistemas que los proveen. A través de una serie de simulaciones de extinción para la …

Litio En Una Encrucijada: Voces Locales Sobre La Reforma Constitucional Del Gobernador Morales Y Su Impacto En El Futuro De La Minería En Jujuy / Lithium At A Crossroads: Local Voices On Governor Morales’ Constitutional Reform And Its Impact On The Future Of Mining In Jujuy, Maxwell Bassin

Independent Study Project (ISP) Collection

En junio de 2023, el gobernador Morales de Jujuy aprobó un cambio en la constitución provincial rápidamente, sin consultar con las comunidades indígenas. Esta reforma prohíbe cortes de rutas, refuerza los derechos de propiedad privada y criminaliza muchas formas de protesta pública. Ahora, hay mucha crítica hacia la reforma, especialmente por parte de las comunidades indígenas y grupos ambientales que tienen miedo de que, sin la posibilidad de protestar, la minería del litio se expandirá en la provincia. Esta minería es peligrosa para las comunidades indígenas porque quiere minar en su tierra y requiere mucha agua aunque el clima de …

The increasing frequency and severity of these wildfires are straining resources and emphasizing the need for a better understanding of the relationship between suppression capacity and fire behavior in wildfire management. The following research addresses the urgent need for more proactive, knowledge-based, and technologically driven fire management strategies, throughout all four stages of wildfire response – fuel and land management, fire preparedness, fire suppression, and post-fire management. Artificial Intelligence (AI) is becoming increasingly significant in climate change adaptation, especially …

Environmental Loss, Displacement, And Anxiety In Portugal: Analyzing News Articles To Differentiate Manifestations Of Environmental Distress, Robin Greene

Independent Study Project (ISP) Collection

Expressions of environmental distress can take different forms, with different symptoms, causes, and treatments. Existing literature generally identifies three primary categories of environmental distress responses: environmental grief, solastalgia, and eco-anxiety. This paper explores these distinctions and identifies words typically associated with each category in Portuguese news articles using Latent Dirichlet Allocation (LDA). LDA is a Natural Language Processing (NLP) technique that groups words into topics and identifies connections between those words based on how often those words appear together in sequences. This paper uses a modified LDA algorithm called GuidedLDA to identify additional keywords within topics defined by a list …

Representations And Realities: Misali Island's Biodiversity In Hybrid Narratives, Justin Ross Whitney

Independent Study Project (ISP) Collection

Marine Protected Areas (MPAs) are complex organisms that ebb and flow between strict and unyielding conservation doctrines often at the cost of community engagement. Misali Island is different. Conceived and advocated for by community members, this organism has navigated a tumultuous tenure of environmental degradation, periods of high and low funding, and a looming tourism presence. On top of these challenges has been a growing fishing community attempting to share in the bounty of this shockingly biodiverse setting. This study sorts through the grey space of Misali Island by applying a hybrid narrative that interfaces the marine context of the …
