A Field Test Of Direct Load Control Of Water Heaters And Its Implications For Consumers, Midrar Adham, Manasseh Obi, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Utilities and customers are now operating more closely than ever. The prevailing numbers of grid-interactive Distributed Energy Resources are being integrated to provide grid reliability and stability. Different methods of control have been implemented to utilize these Distributed Energy Resources, such as Service-Oriented Load Control and Direct Load Control. This paper investigates the issues associated with the latter. A Direct Load Control method is applied to two Distributed Energy Resources, Electric Water Heater and Heat Pump Water Heater. A load shifting scenario is created where each water heater turns off during water draw events that coincide with peak demand periods. …

A Means For Tuning Primary Frequency Event Detection Algorithms, Sean Keene, Landon Hanks, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Power system balancing authorities are routinely affected by sudden frequency fluctuations. These frequency events can precipitate cascading outages and cause damage to both customer-owned and utility equipment. In this document, we describe an Algorithm Evaluation Environment that uses a suite of metrics to evaluate an algorithm and quantify its efficacy. Using the Algorithm Evaluation Environment, a detection algorithm can be tuned to best match the definition of a frequency event as defined by experts within the context of their own balancing area. We demonstrate the utility of the Algorithm Evaluation Environment using a regression-based frequency event detection algorithm. This algorithm …

Incentivizing Distributed Energy Resource Participation In Grid Services, Tylor Slay, John M. Acken, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

The bulk power system is experiencing a dramatic shift as renewable generation growth continues to accelerate. Large-scale renewables adoption will help societies transition to a low-carbon, low-cost, and environmental-friendly electrical power system. However, the transition from a paradigm of generation following load to one where load follows generation will require large-scale interconnection and coordinated operation of Distributed Energy Resources (DERs), supported by open communication protocols. In this future grid scenario, DER aggregations will provide critical grid services that enable high penetration levels of renewable generation. This position paper presents an Energy Service Interface (ESI) that defines scope for ensuring secure, …

Compound Flooding In Convergent Estuaries: Insights From An Analytical Model, Ramin Familkhalili, Stefan A. Talke, David A. Jay

Civil and Environmental Engineering Faculty Publications and Presentations

We investigate here the effects of geometric properties (channel depth and cross-sectional convergence length), storm surge characteristics, friction, and river flow on the spatial and temporal variability of compound flooding along an idealized, meso-tidal coastal-plain estuary. An analytical model is developed that includes exponentially convergent geometry, tidal forcing, constant river flow, and a representation of storm surge as a combination of two sinusoidal waves. Nonlinear bed friction is treated using Chebyshev polynomials and trigonometric functions, and a multisegment approach is used to increase accuracy. Model results show that river discharge increases the damping of surge amplitudes in an estuary, while …

Getting Proactive With Police Proactivity: The Benefits Of Computer-Aided Dispatch For Directing Police Resources To Areas Of Need, Kris Henning, Christian Peterson, Greg Stewart, Kimberly Kahn, Yves Labissiere, Brian Renauer, Renee Mitchell, Sean Sothern

Criminology and Criminal Justice Faculty Publications and Presentations

Sherman and colleagues (2014) argue that crime reductions associated with hot spot policing can be maximized by carefully managing the dosage of supplemental resources delivered. Fully achieving this goal in prior studies has been difficult due to resistance by officers, the use of atypical strategies for directing patrols to target locations, and insufficient attention to the measurement of treatment dosages. This has led to calls for process research examining the implementation of hot spot policing in law enforcement agencies. The current study represents one such effort. The computer-aided dispatch (CAD) system for a large U.S. police department was pre-programmed with …

A Survey Of The Solitary Native Bees Of The Leach Botanical Garden, And Their Floral Associations, Joshua Page

Solitary native bees are known to be diverse, but are not well studied in Oregon. In order to identify the bee genera present in the Leach Botanical Garden, and their floral usage, a survey was conducted over 2020 and 2021. Biweekly sampling was used to collect bees on flowers, in order to obtain floral usage data. Bees were identified to genus with published taxonomic keys. In total, 19 genera of bees were found. Bee abundance fit a normal distribution, and peaked in July. Ceratina and Lasioglossum were a significant proportion of the population, and were present in the garden from …

Vernacular Print, Johann Prüss, And The Fasciculus Temporum, Julia Hines

Fasciculus Temporum

This research discusses biographical information on Strasbourg printer Johann Prüss and his vernacular German work, and offers a statistical and categorical comparison to other contemporary Strasbourg printers and their vernacular German works.

Using the British Library's Incunabula Short Title Catalogue (ISTC) and other sources, I created a table in the appendix that lists all the known vernacular works of each printer and their date of publication. Lastly, this paper discusses the similarities and differences between the 1490 Latin edition of the Fasciculus Temporum and the following German edition printed by Prüss in 1492.

How Tales Of Blood Libel Travel: Depictions Of Jews In Fifteenth-Century European World Chronicles, Rachel Bard

Fasciculus Temporum

This paper considers the correlation between the popularity of Werner Rolevinck’s Fasciculus Temporum and other world chronicles, and the antisemitic tropes and blood libel accusations directed against Jewish communities in later medieval Europe.

The Fasciculus repeats many stock tales of Jewish ritual murder, including a relatively little-known story from Bern, Switzerland, that Rolevinck may have adapted from the Berner Chronik. This paper also considers the connection the first Spanish printing of the Fasciculus Temporum, in Seville in 1480, with the only known Jewish ritual murder accusation in Spain, which dates to 1490, and which in turn may have been …

Robert Lenkiewicz: Witchcraft Collector, Ashley M. Hood

Provenance and Preservation

In 2018, Portland State University purchased a medieval codex containing a 1490 printing of Werner Rolewinck’s Fasciculus Temporum and a 1490 edition of the Malleus Maleficarum printed in Speier, Germany, by Peter Drach. Based on information from the bookseller in France, PSU has concluded that the codex most likely came from the collection of Robert Lenkiewicz (1941-2002), a twentieth-century English figurative painter who amassed a significant collection of rare books and incunables during his life.

Lenkiewicz’s artwork, interests, and book collection revolved around addiction and fanaticism, and one of the more noteworthy sections of his library focused on witchcraft and …

The impacts of the COVID-19 pandemic have been felt across various industries around the world, including the semiconductor industry. The semiconductor industry was boosted by pandemic restrictions as changing consumer habits—driven by the rise in remote work, distance learning, gaming, entertainment, and internet shopping—significantly increased demand for consumer electronic devices to the point that demand for semiconductors far outpaced production. Given the globality and complexity of the semiconductor supply chain, many companies are exploring ways to permanently change workplace collaboration for their employees. In this paper, the Hierarchical Decision Modeling (HDM) method is used to evaluate four possible pandemic semiconductor …

Care Ethics, Religion, And Spiritual Traditions, Inge Van Nistelrooij, Maureen Sander-Staudt, Maurice Hamington

Philosophy Faculty Publications and Presentations

Care Ethics, Religion, and Spiritual Traditions is a collection of original essays that address the intersection between contemporary feminist care ethics and religious morality. Feminist care ethics is one of the most dynamic areas in modern theory. This relational approach to morality emphasizes context, emotion, and imagination over consequences, rules, and rights has only been around for about four decades, with its definition still being negotiated. Still, the respect for this approach is demonstrated by its widespread inclusion in moral discourse. Historically, care has been an overlooked concept in philosophy, but religion's ambivalence toward care ethics is even more pronounced. …
