Seoul National University Agn Monitoring Project. V. Velocity-Resolved Hβ Reverberation Mapping And Evidence Of Kinematics Evolution, Shu Wang, Jong-Hak Woo, Aaron J. Barth, Vardha N. Bennert, Elena Gallo, Edmund Hodges-Kluck, Minjin Kim, Suvendu Rakshit, Tommaso Treu, Hojin Cho

Physics

We present velocity-resolved reverberation lags of Hβ for 20 active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project. We detect unambiguous velocity-resolved structures in 12 AGNs, among which eight objects exhibit symmetric structures, two objects show inflow-like characteristics, and two objects display outflow-like signatures. For two AGNs, we successfully measure the velocity-resolved lags in different years, revealing evidence of evolving broad-line region (BLR) kinematics. By combining our sample with the literature velocity-resolved lags, we find that the symmetric velocity-resolved lags are the most common (40%) type among this sample. The frequency of inflow kinematics is also …

Aiops–Driven Adaptive Anomaly Detection In Evolving Cloud Environments Using Transfer Learning, Mayur Shivakumar

Master's Theses

As cloud-based microservice architectures have become the foundation of contempo- rary enterprise solutions, performance interference, wherein co-located services com- pete for shared resources, remains a significant challenge. This phenomenon, often referred to as the noisy neighbor problem, manifests when one workload unexpect- edly increases the CPU, memory, disk I/O, or network consumption, resulting in latency spikes or throughput degradation for other services. While existing isolation mechanisms (e.g., cgroups and QoS policies) provide some mitigation, they rarely prevent contention entirely, particularly in dynamic, rapidly evolving environments with frequent code deployments.

This thesis proposes an AIOps-driven adaptive anomaly detection framework that integrates …

Using Camera Stations To Investigate Occupancy Probability And Habitat Associations Of Island Spotted Skunks (Spilogale Gracilis Amphiala) On Santa Rosa And Santa Cruz Islands, Desirae Thomaier

Master's Theses

The California Channel Islands are unique in that two islands (Santa Rosa and Santa Cruz) support two endemic mesocarnivores, the island fox (Urocyon littoralis) and the island spotted skunk (Spilogale gracilis amphiala). Following the near-extinction of island foxes in the early 2000s, island spotted skunk populations increased significantly. Now that foxes have recovered, skunk captures have precipitously declined - possibly due to interspecific competition with foxes who have a similar diet but a larger body size and wider temporal niche. It has been proposed that skunks selectively use canyon bottoms and drainages with high vegetation cover and that these areas …

Climate Change And Variability Drive Increasing Exposure Of Marine Heatwaves Across Us Estuaries, Ricardo U. Nardi, Piero L. F. Mazzini, Ryan K. Walter

Physics

Marine heatwaves (MHWs) are among the greatest threats to marine ecosystems, and while substantial advances have been made in oceanic MHWs, little is known about estuarine MHWs. Utilizing a temperature dataset spanning over two decades and 54 stations distributed across 20 estuaries in the United States National Estuarine Research Reserve System, we present a comprehensive analysis of estuarine MHW characteristics and trends. Long-term climate-change-driven warming is driving more frequent MHWs along the East Coast, and if trends continue, this region will be in a MHW state for ~ 1/3 of the year by the end of the century. In contrast, …

Assessing Arterial Compliance: Utilizing A Surrogate Arm Bench Top Model For Oscillometric Blood Pressure Monitoring, Krystal Cardenas

Master's Theses

A study was conducted to evaluate the compliance of artificial artery systems utilizing an adaptation of the Yong-Geddes Surrogate Arm model, composed of a blood pressure cuff, artificial artery, pressure transducers, and flow to replicate physiological conditions to validate oscillometric non-invasive blood pressure measurement methods. The experiment phases included tube, blood pressure cuff, and the surrogate arm compliance tests both in static and dynamic conditions. Tube compliance tests showed that larger diameters resulted in increased compliance, with Sample 1 (smaller inner diameter, ID) resulting in an average compliance of 0.0912 mL/mmHg, and Sample 2 (bigger ID) resulting in 0.1597 mL/mmHg. …

Dr. Lemieux and the mechanical engineering department at Cal Poly are renowned for the countless projects that allow students to be a part of hands-on learning and the “Learn by Doing” experience. One such experience is the wind energy class that requires students to design, build, and test wind turbine rotors; however, a test stand for these rotors is needed. Dr. Lemieux and the senior project team will design and build a test stand that will enable the simultaneous testing of two student-designed rotors at the existing wind turbine site. In addition to energy measurement, Lemieux emphasizes the importance of …

Circular Restricted Three Body Manifold Trajectories Via Koopman Operator Theory, Lindsey Langton

Master's Theses

There are a multitude of computational techniques capable of modeling the behavior of nonlinear dynamic systems over time. In the field of astrodynamics, the most frequently used tools are numerical integrators, specifically Runge-Kutta algorithms. These algorithms have successfully produced numerous two-body trajectories, as well as an increasing number of three-body trajectories when two-body dynamic models fail to produce Δv values within the realm of mission feasibility. Koopman operator theory is an alternative method for modeling nonlinear dynamic behavior that captures an approximation of a nonlinear dynamic system on a defined basis in the Hilbert space. The Koopman operator is an …

Development Of Ex-Situ Accelerated Chemical Stress Test Protocol For Common Anionic Exchange Membrane Chemistries, Michael D. Friend, Michael D. Friend

Master's Theses

The development of sustainably produced hydrogen fuel (“green hydrogen”) is key for the transition to clean energy sources. Green hydrogen is produced via water electrolysis. As with many clean energy sources, one of the major barriers for scaling water electrolysis is cost. A newer category of water electrolysis is Anionic Exchange Membrane (AEM) water electrolysis. AEM electrolysis systems have the potential to cost less as they do not require the expensive precious metal catalysts the current high preforming Proton Exchange Membrane water electrolysis technologies do. However, AEM lifetimes must be long enough to be cost competitive and AEM chemical durability …

Tiny Temp Neonatal Intensive Care Unit Infant Temperature Monitor, Alexandria Lukacsffi, Sydney Dedrick

Biomedical Engineering

This document outlines the key steps taken in the specification, design, and functionality of the Tiny Temp Neonatal Intensive Care Unit Infant Temperature Monitor. The BICEP team identified temperature monitors for infants in incubators in the NICU as an area of need after surveying hospitals in the San Luis Obispo area. Current thermometers are oversimplified in design, consisting of only the temperature probe and a piece of adhesive holding the probe directly onto the infant's skin. As a result, the adhesive is weak to prevent harm to the infant and, therefore, falls off the infant easily and frequently, posing a …

Vertical Structure Of Subsurface Marine Heatwaves In A Shallow Nearshore Upwelling System, Gavin Plume, Ryan K. Walter, Isabelle Cobb, Michael Dalsin, Piero L. F. Mazzini, Nathan P. Shunk, Ian C. Robbins, Thomas P. Connolly

Physics

Marine heatwaves (MHWs) are increasing in frequency and intensity globally and are among the greatest threats to marine ecosystems. However, limited studies have characterized subsurface MHWs, particularly in shallow waters. We utilized nearly two decades of full water-column (~ 10 m) observations from a unique automated profiler in central California to characterize, for the first time, the vertical structure of MHWs in a shallow nearshore upwelling system. We found MHWs have similar average durations and intensities across all depths, but there were ~ 17% more bottom MHW days than surface MHW days. Nearly one third of bottom MHWs occurred independently …

Reenvisioning Identities That Precede Us: “Body Acknowledgement” As Social Justice Practice Within A Communication Ethics Course Redesign, Wendy Kz Anderson, Ollivia Webster, Nicole Yang, Cass Bryant, Taylor Herr

Feminist Pedagogy

We infuse this conversation of “body neutrality” through social justice responsiveness (compassion, equity, and accountability of body/presence privilege) by specifically attending to intersections of race, gender, and body mindset built into our identities. In reimagining the term “body-neutrality” through identity engagement, we introduce the term “body acknowledgment” as an active interpretative state. As a co-authored pedagogical “co-conspiring” for racial justice (Houdek and Ore, 2021, p. 92), we (instructor, teaching assistants, and previous students) offered a course redesign centering social justice strategies to address the following question: How can dialogue about intersectional communication work toward redesigning learning with difference and develop …

Offshore Wind Farms Could Impact Coastal Marine Heatwaves In Eastern Boundary Upwelling Systems, Michael Dalsin, Ryan K. Walter, Piero L.F. Mazzini

Physics

Analysis of ecosystem impacts from offshore wind (OSW) farm development has primarily focused on localized effects. However, in Eastern Boundary Current Upwelling Systems (EBUS) like the California Current, OSW farms can modify the intensity and spatial structure of wind-driven upwelling, inducing non-local (tens of kms away) changes to seawater temperature. Recent numerical modeling research determined that a hypothetical upper bound full buildout of OSW farms in central California could warm coastal waters through a reduction in upwelling. Here, we examine the sensitivity of coastal marine heatwaves (MHWs), which are prolonged extreme seawater temperatures that are among the greatest threats to …
