A Study Of Marine Terrace Formation Along The California Central Coast, Mary C. Devlin

Natural Resources Management and Environmental Sciences

Marine terrace formation is in many instances attributed to wave action, and shore platforms are often called “wave-cut”. However, alternative models for marine terrace formation suggest that other types of physical and chemical weathering have a more central role in the formation of marine terraces than is widely acknowledged. Roering and Retallack (2012) concluded that the roles of subaerial physical and chemical weathering are significant, and played a major role in the formation of the terraces. In this study, weathering of beach cliffs and shore platforms associated with marine terraces at eight sites in two different locations along the central …

Agricultural Communications Lesson Plans For High School Agriculture Programs, Caitlin Anne Stanton

Agricultural Education and Communication

In today’s workforce, individuals are expected to be able to communicate effectively through all means of communication. This includes video, graphics, emails, social media, and in person. In the agriculture industry, these means of communication have become crucial to promoting agricultural literacy throughout the world. It is important for young people to have a grasp on professionally utilizing these communication methods so that they can use them in future careers as well as advocating for the agriculture industry. The role of technology and social media is rapidly increasing in everyday life and becoming a key learning tool in secondary education. …

In addition to an evaluation of the twelve criteria, a plan is included on how Turlock Christian FFA will be conducting their graduate follow-ups in the future, including …

A High Quality, Eulerian 3d Fluid Solver In C++, Lejon Anthony Mcgowan

Computer Science and Software Engineering

Fluids are a part of everyday life, yet are one of the hardest elements to properly render in computer graphics. Water is the most obvious entity when thinking of what a fluid simulation can achieve (and it is indeed the focus of this project), but many other aspects of nature, like fog, clouds, and particle effects. Real-time graphics like video games employ many heuristics to approximate these effects, but large-scale renderers aim to simulate these effects as closely as possible.

In this project, I wish to achieve effects of the latter nature. Using the Eulerian technique of discrete grids, I …

Faraday-Talbot Effect From A Circular Array Of Pillars, Jessica J. Pilgram

Physics

When an oil bath is vertically oscillating with an acceleration above some critical value, known as the Faraday threshold, the bath surface becomes unstable and nonlinear standing wave patterns emerge. One phenomenon that has been observed above the Faraday threshold is the formation of Faraday-Talbot carpets, resulting from near-field diffraction. The optical Talbot effect occurs when a monochromatic wave passes through a diffraction grating. In the near-field, the formation of self- images is observed at integer multiples of what is known as the Talbot length. These two-dimensional patterns have various applications including X-ray imaging and atom and particle trapping. Two- …

Investigation Of Neutron Induced Ternary Fission With The Niffte Time Projection Chamber, Alex C. Kemnitz

Physics

Ternary fission is a rare occurrence in which three particles are produced from a single fission event. This analysis uses tracked fission event data recorded by NIFFTE’s time projection chamber with a series of refined cuts to isolate all possible ternary events. The experiment used two targets, each consisting of two isotopes; one target was Pu-239 and U-235, and the other was U-238 and U-235. The data was used to measure the ternary/binary fission ratios for each isotope. The ratios for the Pu-239 and U-235 target that were found are shown to be too high due to alpha contamination. The …

Within this document are the plans, decisions, and processes used to create our final product for Deutsches Museum.

Alternative Mission Concepts For The Exploration Of Outer Planets Using Small Satellite Swarms, Andrew Gene Blocher

Master's Theses

Interplanetary space exploration has thus far consisted of single, expensive spacecraft missions. Mission costs are particularly high on missions to the outer planets and while invaluable, finite budgets limit our ability to perform extensive and frequent investigations of the planets. Planetary systems such as Jupiter and Saturn provide extremely complex exploration environments with numerous targets of interest. Exploring these targets in addition to the main planet requires multiple fly-bys and long mission timelines. In LEO, CubeSats have changed the exploration paradigm, offering a fast and low cost alternative to traditional space vehicles. This new mission development philosophy has the potential …

H0licow Vii: Cosmic Evolution Of The Correlation Between Black Hole Mass And Host Galaxy Luminosity, Xuheng Ding, Tommaso Treu, Sherry H. Suyu, Kenneth C. Wong, Takahiro Morishita, Daesong Park, Dominique Sluse, Matthew W. Auger, Adriano Agnello, Vardha Nicola Bennert, Thomas E. Collett

Physics

Strongly lensed active galactic nuclei (AGN) provide a unique opportunity to make progress in the study of the evolution of the correlation between the mass of supermassive black holes (M_BH⁠⁠) and their host galaxy luminosity (L_host). We demonstrate the power of lensing by analysing two systems for which state-of-the-art lens modelling techniques have been applied to deep Hubble Space Telescope imaging data. We use (i) the reconstructed images to infer the total and bulge luminosity of the host and (ii) published broad-line spectroscopy to estimate M_BH using the so-called virial method. We then enlarge …

Verifying The Cause Of Panel Cracking - A Case Study, Jack Robinson, Stewart Hooks, John W. Lawson

Architectural Engineering

Despite the multitude of benefits tilt-up construction has to offer in low rise commercial buildings, there is still room for improvements in the performance of tilt-up buildings. One opportunity for improvement is to minimize a particular, undesirable cracking pattern often seen in concrete tilt-up panels (See Figure 1), which in some cases requires significant cosmetic patching (See Figure 2). This concrete cracking can first appear as non-problematic and non-structural, but even small cracks can become weathered and lead to water intrusion and rebar corrosion. At the very least, these cracks are cosmetic concerns for the owner or tenant potentially resulting …

Why Do We Care?: A Natural History Of Noddings’ Ethical Theory, Walter Jason Niedermeyer

Between the Species

Noddings’ theory of caring, which is nearing its 35^th anniversary, has failed to garner the attention of the more classical theories of ethics. This slight may be due to its relative youth, or the historical support for other constructs, but if examined through the lens of evolutionary biology, the validity of Noddings might be tested. Using recent discoveries from the emerging fields of cognitive ethology and neuroscience, I have evaluated whether there exists evolutionary underpinnings for her theory. My analysis makes it apparent that the empathy and altruism required for the practice of caring are as much a product …

Xenotransplantation, Subsistence Hunting And The Pursuit Of Health: Lessons For Animal Rights-Based Vegan Advocacy, Nathan M. Nobis

Between the Species

I argue that, contrary to what Tom Regan suggests, his rights view implies that subsistence hunting is wrong, that is, killing animals for food is wrong even when they are the only available food source, since doing so violates animal rights. We can see that subsistence hunting is wrong on the rights view by seeing why animal experimentation, specifically xenotransplanation, is wrong on the rights view: if it’s wrong to kill an animal to take organs to save a human life, it’s wrong to kill an animal to eat that animal to save a human life or improve …

Nozick’S Libertarian Critique Of Regan, Josh Milburn

Between the Species

Robert Nozick’s oft-quoted review of Tom Regan’s The Case for Animal Rights levels a range of challenges to Regan’s philosophy. Many commentators have focussed on Nozick’s putative defence of speciesism, but this has led to them overlooking other aspects of the critique. In this paper, I draw attention to two. First is Nozick’s criticism of Regan’s political theory, which is best understood relative to Nozick’s libertarianism. Nozick’s challenge invites the possibility of a libertarian account of animal rights – which is not as oxymoronic as it may first sound. Second is Nozick’s criticism of Regan’s axiological theory, which is best …

The Influence Of Natural Sounds On California Ground Squirrel (Otospermophilus Beecheyi) Vigilance And Predator Detection, Christopher M. Garvin, My-Lan T. Le, Clinton D. Francis

STAR Program Research Presentations

Many animals rely on the acoustical environment for functions spanning mate attraction, navigation and predator and prey detection. However, recent research suggests that the context of the acoustic environment can greatly influence the propagation and reception of acoustic signals and cues, potentially interfering with the ability of animals to perceive important environmental cues. Here, we sought to determine whether natural sounds influence vigilance and predator detection in the California ground squirrel (Otospermophilus beecheyi). In a manipulative field experiment, we measured squirrel vigilance behavior under three conditions: playback of river rapid noise, playback of cicada chorus noise and a control, unmanipulated …

Digital Motor Control For Hybrid-Electric Aircrafts, Aala M. Al Hasan, Kurt J. Kloesel

STAR Program Research Presentations

Transforming aviation to improve aircraft shapes, propulsion and efficiency has led to studies for future electric aircrafts that consume only half as much fuel. This project involves thermodynamics modeling and electric power system modeling for turbo-electric generations systems and battery systems for hybrid electric aircrafts. The fundamentals of a digital motor control driver were studied through the use of a fractional horsepower development kit. The investigations were supplemented with automated motor controller software that identifies, tunes and controls the motor, and exploits similarities and differences between all motors. A file was modified that stores all the parameters, such as inductance …

Investigating The Role Of Regulation In Resilience Of Microbial Communities Under Fluctuating Environmental Conditions, Asaad Ahmed, Serdar Turkarslan

STAR Program Research Presentations

Gene regulatory networks are thought to be a vital contribution to microbial resilience in a fluctuating environment. Known gene regulatory networks were utilized to elucidate how the sulfate-reducing bacteria Desulfovibro vulgaris regulates its survival in its relative fluctuating environment while evolving to form a symbiotic relationship with the archaeal organism, Methanococcus maripaludis. By using transposon gene knockout methods to form transcription factor mutants in Desulfovibro vulgaris, the effect on the regulatory network is observed when the bacteria is co-cultured with Methanococcus maripaludis. Transferring methods to simulate fluctuating environments were used to induce transcription of regulatory genes. To measure the extent …
