Settling Performance In Wastewater Fed High Rate Algae Ponds, Elliott Blake Ripley

Master's Theses

Although high rate algae ponds (HRAPs) are a proven wastewater treatment technology with numerous environmental, social, and economic benefits, their widespread use has been hindered by inconsistent and unreliable settling performance. Hence, the goal of this thesis is to investigate how specific operational parameters affect the settling performance of HRAPs. Nine HRAPs (30 m² surface area, 0.3 m depth) were operated as three triplicate sets, with each set run on either a 2, 3, or 4 day HRT continuously from January 25, 2012 through April 11, 2013. Settling performance was determined (i) by measuring the TSS of Imhoff cone …

Cuda Enhanced Filtering In A Pipelined Video Processing Framework, Austin Aaron Dworaczyk Wiltshire

Master's Theses

The processing of digital video has long been a significant computational task for modern x86 processors. With every video frame composed of one to three planes, each consisting of a two-dimensional array of pixel data, and a video clip comprising of thousands of such frames, the sheer volume of data is significant. With the introduction of new high definition video formats such as 4K or stereoscopic 3D, the volume of uncompressed frame data is growing ever larger.

Modern CPUs offer performance enhancements for processing digital video through SIMD instructions such as SSE2 or AVX. However, even with these instruction sets, …

Master's Theses

The control of multiple unmanned aerial vehicles (UAVs) in a swarm or cooperative team scenario has been a topic of great interest for well over a decade, growing steadily with the advancements in UAV technologies. In the academic community, a majority of the studies conducted rely on simulation to test developed control strategies, with only a few institutions known to have nurtured the infrastructure required to propel multiple UAV control studies beyond simulation and into experimental testing. With the Cal Poly UAV FLOC Project, such an infrastructure was created, paving the way for future experimentation with multiple UAV control systems. …

Early Forest Fire Heat Plume Detection Using Neural Network Classification Of Spectral Differences Between Long-Wave And Mid-Wave Infrared Regions, Raul-Alexander Aldama

Master's Theses

It is difficult to capture the early signs of a forest fire at night using current visible-spectrum sensor technology. Infrared (IR) light sensors, on the other hand, can detect heat plumes expelled at the initial stages of a forest fire around the clock. Long-wave IR (LWIR) is commonly referred to as the “thermal infrared” region where thermal emissions are captured without the need of, or reflections from, external radiation sources. Mid‑wave IR (MWIR) bands lie between the “thermal infrared” and “reflected infrared” (i.e. short-wave IR) regions. Both LWIR and MWIR spectral regions are able to detect thermal radiation; however, they …

Addressing The Administration Of Planned Developments: The Case Of Arroyo Grande, California, Matthew J. Downing

Master's Theses

The City of Arroyo Grande, California has a problem administering the

regulations of five Planned Developments in the City. This problem arises

from these regulations being included in a 167-page appendix at the back of

the City’s Development Code. This appendix includes the original approvals

for the Developments. It also includes amendments to those approvals.

These amendments are only added to the appendix. Therefore, changes to

the regulations governing the Planned Developments are not tracked. It

takes City staff considerable amounts of time to research answers when

members of the public have questions regarding development in one of these

Developments. …

A Quantitative Survey: Are Twitter Advertisements Effective For College Students?, Christia J. Brockman

Communication Studies

Social Media websites are rapidly being overrun by advertisements, but is this blitz of advertising destroying the social media experience? Twitter, one of today’s most popular social media sites, increased its revenues from $45,000,000 in 2010 to $259 million in 2013. This exponential growth is surprising given the large portion of Twitter users who are between the ages of 18 to 25 with lower annual incomes. In analyzing whether advertising on Twitter is effective on college students, statistical results from a survey conducted among college students at California Polytechnic State University, San Luis Obispo, reveal that Tweeters in this sample …

A Mouse Model Of Aortic Endothelial Denudation And Neointimal Formation, Ashkon C. Nehzati

Biomedical Engineering

More than 385,000 people die from coronary heart disease (CHD) annually and treatment costs $108.9 billion each year including the cost of health care services, medications, and lost productivity. CHD decreases heart function by limiting oxygen and nutrient transport carried through the coronary arteries. A complete block to the coronary arteries causes a myocardial infarction in response to an elimination of blood supply to cardiomyocytes. Partial occlusion results in insufficient blood supply to cardiomyocytes, producing myocardial ischemia and angina, which are usually treated with intravascular stents deployed percutaneously, before myocardial infarction occurs. Stents are the most common ways to expand …

An Educational Video And Research Experiment On The Longevity Of Chicken Eggs, Kyle Patrick Mcdonald

Agricultural Education and Communication

The purpose of this project was to create a video designed to educate the public about chicken egg storage and refrigeration. The information in the video was based on a research experiment performed by the author, which was designed to measure the chronological decline of internal egg quality over a ten-week period. By creating an educational video about the longevity of chicken eggs, it is hoped that consumers will learn to keep their eggs past their sell-by dates. This project includes an educational video as well as an outline for a research project.

The Relationship Between Vitamin D Status Of Adult Women And Diet, Sun Exposure, Skin Reflectance, Body Composition, And Insulin Sensitivity, Marisa M. Mcadler

Master's Theses

As the prevalence of vitamin D deficiency continues to grow, mounting evidence supporting its link with chronic disease strengthens suggesting vitamin D’s candidacy in the prevention and treatment of multiple disease states and their complications. Dietary guidelines, however, do not take sun exposure into account. The present study sought to explore the impact of sun exposure on vitamin D status (serum 25(OH)D), and identify other significant determinants of serum levels which may have the greatest effects on overall health. Participants (n = 34) were pre-menopausal women aged 18 to 50 years (mean age 39 ± 6 years), who had their …

Modeling And Analysis Of A Dynamic Voltage Regulator, Timothy David Haskell

Master's Theses

Increased government funding and incentives in recent years has led to an increase in the number of grid-tied renewable energy sources as their economic benefits become more renowned. Unfortunately, the outputs of these renewable resources are often highly variable, resulting in undesirable voltage disruptions that are harmful to sensitive loads. In addition to the energy variability of renewable energy sources, random voltage sags, swells and disruptions are already a major issue in power systems. Recent advances in power electronic devices have provided a platform for new solutions to the voltage support problem in power systems. One promising solution is the …

Design Of An Experimental Approach To Study The Growth Of Biofilm On Polymethylmethacrylate, Eireen S. Escalona

Biomedical Engineering

Biofilms are present in virtually every solid-liquid contact surface and are partially responsible for some diseases and water cleaning. They are a community of a variety of organisms that live symbiotically and are bound together by extracellular polymeric substances, or EPS. Biofilms go through five stages of development. These include initial and irreversible attachments, maturations I and II, and dispersion. In the dental world, biofilms are often associated with mouth infections including dental caries, gingivitis and periodontitis. Elderly denture wearers are susceptible to the pathogen-causing bacteria associated with these diseases, particularly those who have Alzheimer's disease or other forms of …

Finite Element Analysis Of The Nerve Cuff To Determine Usability And Stress Analysis During Regular Use, Vivek Machhi

Biomedical Engineering

To determine the stress analysis on the Nerve Cuff by MicroProbes, a finite element analysis was conducted. A simplified model was created in Solid Works using the geometry of the basic model of the nerve cuff. The solid model was then imported into Abaqus and the appropriate materials, boundary conditions, and loads were designated. Initially a tensile test simulation was conducted using a tensile force of 2.87 Newtons. The maximum stress experienced with this tensile force was 8.225 MPa which was greater than the ultimate tensile strength of 5.5 MPa of Silicone. Both the actual tensile test and the tensile …

Nonhuman Animals: Not Necessarily Saints Or Sinners, Cheryl E. Abbate

Between the Species

Higher-order thought theories maintain that consciousness involves the having of higher-order thoughts about mental states. In response to these theories of consciousness, an attempt is often made to illustrate that nonhuman animals possess said consciousness, overlooking an alarming consequence: attributing higher-order thought to nonhuman animals might entail that they should be held morally accountable for their actions. I argue that moral responsibility requires more than higher-order thought: moral agency requires a specific higher-order thought which concerns a belief about the rightness or wrongness of affecting another’s mental states. This “moral thought” about the rightness or wrongness is not yet demonstrated …
