Energy-Based Cavitation Erosion Risk Modeling Of Sheet-To-Cloud Cavitation Of A Hydrofoil, Catherine Baum

Electronic Theses and Dissertations Archive

Cavitation erosion is a significant challenge in marine and hydraulic systems because the relationship between cavitation dynamics and material damage is difficult to quantify. This study evaluates an energy-based cavitation erosion risk model using large-eddy simulations (LES) of sheet-to-cloud cavitation on a hydrofoil operating under conditions representative of experiments conducted in the United States Navy's Large Cavitation Channel (LCC). Six erosion risk indicators derived from the energy balance of a collapsing vapor structure were investigated using multiple driving-pressure fields. The results showed that indicators based on pressure derivatives contributed negligibly to the predicted erosive energy, while indicators based on the …

An Investigation Of The Relationships Between Visual Perceptual Expertise For Music Notation, Dyslexia Risk, And Musical Experience: A Pilot Study, Janel Kathleen Long

Electronic Theses and Dissertations Archive

Musicians who are also dyslexic often report various challenges related to reading music notation.

The findings of replication studies conducted in the early 2010s

led many to declare that science was in the midst of a “replication

crisis.” Since then, a growing number of reforms have been

proposed and tested. The field of empirical legal studies seems

behind other fields such as psychology, economics, political science,

medicine, biology, and others that have taken significant steps

toward uncovering the general reliability of the field’s empirical

work, investigating the causes of observed unreliability, and

instituting and testing the effects of various reforms. The purpose of

this Article is to summarize what we know about the reliability …

Noneconomic Tort Damages And Biased Beliefs About Vulnerability To Harm, Roseanna Sommers, Nathan Cheek

DePaul Law Review

The American tort system aspires to provide fair compensation to injured plaintiffs, regardless of socioeconomic status, race, religion, or gender. Recent experimental evidence from psychology suggests, however, that factfinders consistently judge identical harms as less severe when experienced by individuals of lower socioeconomic status (SES). People presume, for instance, that a paper cut hurts a wealthy person more than a less well-off person, that domestic violence inflicts greater suffering on a high-SES woman than a lower-SES woman, and that bullying harms a fiveyear- old from a high-SES family more severely than one from a low- SES family. This Essay examines …

Subjective Due Process As A Legal Standard: Using Lay Judgments As A Basis For Evaluating Emerging Remote And Impersonal Civil Procedures, Tom Tyler

DePaul Law Review

The forums through which the civil justice system operates are

rapidly changing toward the adoption of remote and impersonal

procedures. These changes are being driven by efforts to manage

large case loads through a system which has limited resources.

Authorities supporting these evolving forums suggest that they

respond to litigant concerns for rapid and inexpensive case

management procedures. A review of research suggests that, in

contrast to this perspective, people are actually very sensitive to

whether they believe they receive due process. Such due process

concerns have been identified through the literature of procedural

justice. They reflect four judgments about …
