Tractor manufacturers set strict security on the electrical components of their tractors, making it difficult for tractor owners to diagnose and monitor their tractors on their own. The UltraBlue Tractor Hacking project is a solution to this problem, allowing tractor owners to perform diagnostics and monitor the equipment they purchased without having to go through dealerships. From talking to farmers, we found that they valued a diagnostic tool that allows for clearing and resetting Diagnostic Trouble Codes (DTCs), viewing diagnostic data pertaining to a specific …

Assessing Cryptic Dispersal And Movement In The Lompoc Kangaroo Rat, Katherine A. Belnick

Biological Sciences

Lompoc kangaroo rats (LKR, Dipodomys heermanni arenae) are small rodents that reside in sand dunes from Pismo to Orcutt, including the Oceano Dunes State Vehicular Recreation Area (SVRA), in Oceano, CA. In the SVRA, some of these individuals live in habitat islands, which are habitat fragments of dense vegetation disrupted by empty, bare sand in between them. Recreational vehicle activity is permitted in the Oceano Dunes, which has caused persistence habitat fragmentation. Kangaroo rats are known to disperse between habitat islands and are suspected to do so via a special type of dispersal: cryptic dispersal. This dispersal mode, if it …

Conspiratorial Thinking And Personality, Fiona R. Papile

Social Sciences

Why do some people believe in conspiracies more than others? Previous research suggests that variables such as education level, gender, race, or political preference are not useful in a predictive capacity, so what individual traits or characteristics make someone more likely to believe in conspiracy theories?

Locus of control is a psychological personality trait that indicates how an individual attributes the causes and outcomes of life events. Locus of control ranges from a more internally located locus, to more externally located. Internally located individuals believe that their own actions primarily impact the outcomes of events, whereas externally located individuals believe …

The Free Arena Of Literature: Science Fiction Films’ Critiques Of Capitalism In The United States, John (Jack) Michael Bilello

History

Capitalism is an inherently flawed system. The ideologies of Karl Marx have remained relevant for their critiques of the system, yet socially, his ideas are not accepted in the capitalist United States. Capitalism, as the dominant economic system of western civilization, has become synonymous with patriotism in the U.S. This has proved incredibly harmful to criticisms of capitalism, as they are met with questions of allegiance and patriotism rather than a careful reconsideration of ideals. Through science fiction films, these ideas that are usually difficult to express become much more palatable to a capitalist society. But to fully appreciate the …

A Survey Of Computer Graphics Facial Animation Methods: Comparing Traditional Approaches To Machine Learning Methods, Joseph A. Johnson

Ultra-High-Energy Neutrino Detection Antenna Simulations, Nicholas C. Garcia

Electrical Engineering

Neutrinos allow researchers to investigate high-energy galactic phenomena, such as supernovae and black holes. Neutrinos interact with their surroundings via the weak nuclear force and therefore, travel unattenuated through space and are not deflected by electromagnetic fields. However, they do rarely interact with other particles. When neutrinos interact with nucleons (protons or neutrons) in a dielectric medium (i.e.: ice sheets), they are detectable through a cone of coherent electromagnetic radiation (Askaryan Radiation) created by the particle shower generated from the neutrino interaction [1]. The Radio Neutrino Observatory in Greenland (RNO-G) detects UHE neutrinos greater than 100 PeV (10¹⁵ eV) …

The Ill-Treatment Of Their Countrywoman: Liberated African Women, Violence, And Power In Tortola, 1807–1834, Arianna Browne

Master's Theses

In 1807, Parliament passed an Act to abolish the slave trade, leading to the Royal Navy’s campaign of policing international waters and seizing ships suspected of illegal trading. As the Royal Navy captured slave ships as prizes of war and condemned enslaved Africans to Vice-Admiralty courts, formerly enslaved Africans became “captured negroes” or “liberated Africans,” making the subjects in the British colonies. This work, which takes a microhistorical approach to investigate the everyday experiences of liberated Africans in Tortola during the early nineteenth century, focuses on the violent conditions of liberated African women, demonstrating that abolition consisted of violent contradictions …
