Extending Model Checking Using Inductive Proofs In Distributed Digital Currency Protocols, Kyle R. Storey Jun 2023

Extending Model Checking Using Inductive Proofs In Distributed Digital Currency Protocols, Kyle R. Storey

Theses and Dissertations

Model checking is an effective method to verify both safety and liveness properties in distributed systems. However, the complexity of model checking grows exponentially with the number of entities which makes it suitable only for small systems. Interactive theorem provers allow for machine-checked proofs. These proofs can include inductive reasoning which allows them to reason about an arbitrarily large number of entities. However, proving safety and liveness properties in these proofs can be difficult. This work explores how combining model checking and inductive proofs can be an effective method for formally verifying complex distributed protocols. This is demonstrated on a …

Acoustic Directivity: Advances In Acoustic Center Localization, Measurement Optimization, Directional Modeling, And Sound Power Spectral Estimation, Samuel David Bellows Jun 2023

Acoustic Directivity: Advances In Acoustic Center Localization, Measurement Optimization, Directional Modeling, And Sound Power Spectral Estimation, Samuel David Bellows

Theses and Dissertations

Sound radiation from an acoustic source typically exhibits directional behavior, as is the case for the human voice, musical instruments, and loudspeakers, to name just a few. The necessity of directional data for many applications, such as sound source modeling, microphone placement, room acoustical design, and auralization, motivates directivity measurements. However, these measurements require careful understanding and implementation to produce the most meaningful results. Accordingly, this dissertation addresses several topics relevant to directivity theory, measurement, processing, and application. It first expands and amends previously published concepts of an acoustic source center and demonstrates the close relationship between the center and …

False Memories For Stereotypes: Effects Of Attention And Delay, Maria Corea Dubon Jun 2023

False Memories For Stereotypes: Effects Of Attention And Delay, Maria Corea Dubon

Theses and Dissertations

The present study investigated the conditions in which stereotype-based beliefs elicit the creation of false memories for information consistent with racial-occupational expectations and the extent to which attentional depletion increases this likelihood. This was examined in the context of racial-occupational stereotypes for White and Latino individuals. Participants were presented with pictures of faces paired with stereotype-consistent and -inconsistent occupational information. One group of participants was exposed to these stimuli while also completing an additional task designed to divide their attention. Their memory for these pairings was tested in both an immediate and delayed recognition test. Due to the social reliance …

Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell Jun 2023

Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell

Theses and Dissertations

This thesis explores how Nobel laureate Olga Tokarczuk's 2008 novel, Drive Your Plow Over the Bones of the Dead, engages with William Blake's life and his writings on animal welfare and speaks to current conversations about multispecies justice in the environmental humanities. It argues, first, that in recognizing how this novel's protagonist, Janina, selectively reads Blake to rationalize retributive justice, readers should resist a tendency to mistake this character for Tokarczuk's ideal advocate for environmental ethics. Secondly, it asserts that legal scholars' division between retributive and restorative justice offers valuable framework for approaching both this novel and ongoing debates about …
