Endothelial And Smooth Muscle-Dependent Vascular Reactivity In Immature Arterialized Collateral Capillaries, Caitlin Koeroghlian Jun 2014

Endothelial And Smooth Muscle-Dependent Vascular Reactivity In Immature Arterialized Collateral Capillaries, Caitlin Koeroghlian

Biomedical Engineering

Peripheral arterial occlusive disease (PAOD) occurs due to the build up of atherosclerotic plaque and reduces blood flow to cause chronic ischemia. Patients with PAOD may experience intermittent claudication, or the pain in limb skeletal muscles due to a decease in blood flow. Collateral arteries can act as a natural bypass and improve blood flow to hypoxic tissue by creating an alternate route for blood to flow, but not all patients with PAOD have pre-existing collateral networks. Animal studies indicate that tissues without pre-existing collateral networks can form de novo collaterals from capillaries following occlusion of a feed artery. Unfortunately, …


Functional Vasodilation Is Impaired In Arterialized Capillaries In The Spinotrapezius, Joshua P. Cutts Jun 2014

Functional Vasodilation Is Impaired In Arterialized Capillaries In The Spinotrapezius, Joshua P. Cutts

Biomedical Engineering

Ischemic diseases are the result of atherosclerotic plaques, which occlude conduit arteries. Ischemic disease in different tissues leads to different conditions, such as coronary artery disease (CHD), cerebrovascular disease (CVD), and peripheral arterial occlusive disease (PAOD). Patient vasculature architecture is variable; some patients having many collateral vessels, which are connect one arterial branch to another, and readily serve as natural bypass routes to atherosclerotic occlusions, to enlarge and provide blood flow to tissue distal to the occlusion. Patients with many natural collateral vessels are ischemia protected. Unfortunately, not all patients have collateral arterioles to remodel into conduit vessels and provide …

Real-Time 3d Person Tracking And Dense Stereo Maps Using Gpu Acceleration, Kendall Merriman Jun 2014

Real-Time 3d Person Tracking And Dense Stereo Maps Using Gpu Acceleration, Kendall Merriman

Master's Theses

Interfacing with a computer, especially when interacting with a virtual three di- mensional (3D) scene, found in video games for example, can be frustrating when using only a mouse and keyboard. Recent work has been focused on alternative modes of interactions, including 3D tracking of the human body. One of the essential steps in this process is acquiring depth information of the scene. Stereo vision is the process of using two separate images of the same scene, taken from slightly different positions, to get a three dimensional view of the scene. One of the largest issues with dense stereo map …

Sensitivity Of Stormwater Management Solutions To Spatial Scale, Jeffrey Michael Barich Jun 2014

Sensitivity Of Stormwater Management Solutions To Spatial Scale, Jeffrey Michael Barich

Master's Theses

Urbanization has considerably altered natural hydrology of urban watersheds by increasing runoff volume, producing higher and faster peak flows, and reducing water quality. Efforts to minimize or avoid these impacts, for example by implementing low impact development (LID) practices, are gaining momentum. Designing effective and economical stormwater management practices at a watershed scale is challenging; LIDs are commonly designed at site scales, considering local hydrologic conditions (i.e., one LID at a time). A number of empirical studies have documented hydrologic and water quality improvements achieved by LIDs. However, watershed scale effectiveness of LIDs has not been well studied. Considering cost, …

Chronic dehydration is an endemic problem for many population groups. Current methods of monitoring hydration status are invasive, time consuming, cannot be performed while exercising, and require lab resources. A proposed solution is a wearable, continuous, and non-invasive device that uses harm-free ultrasonic pulses to detect changes in tissue hydration status over time. Customer and engineering requirements were defined and used to guide the design process. Literature reviews were performed to identify essential information on dehydration, assess current methods, discover state of the art devices, and describe ultrasonic theory. Market research was performed to identify athletes as the target population …


A Multi-Gpu Compute Solution For Optimized Genomic Selection Analysis, Trevor Devore Jun 2014

A Multi-Gpu Compute Solution For Optimized Genomic Selection Analysis, Trevor Devore

Master's Theses

Many modern-day Bioinformatics algorithms rely heavily on statistical models to analyze their biological data. Some of these statistical models lend themselves nicely to standard high performance computing optimizations such as parallelism, while others do not. One such algorithm is Markov Chain Monte Carlo (MCMC). In this thesis, we present a heterogeneous compute solution for optimizing GenSel, a genetic selection analysis tool. GenSel utilizes a MCMC algorithm to perform Bayesian inference using Gibbs sampling.

Optimizing an MCMC algorithm is a difficult problem because it is inherently sequential, containing a loop carried dependence between each Markov Chain iteration. The optimization presented in …

Master's Theses

Recent growth in the commercial availability of consumer grade 3D user interface devices like the Microsoft Kinect and the Oculus Rift, coupled with the broad availability of high performance 3D graphics hardware, has put high quality 3D user interfaces firmly within the reach of consumer markets for the first time ever. However, these devices require custom integration with every application which wishes to use them, seriously limiting application support, and there is no established mechanism for multiple applications to use the same 3D interface hardware simultaneously. This thesis proposes that these problems can be solved in the same way that …


A Comparison Of Image Processing Techniques For Bird Detection, Elsa Reyes Jun 2014

A Comparison Of Image Processing Techniques For Bird Detection, Elsa Reyes

Master's Theses

Orchard fruits and vegetable crops are vulnerable to wild birds and animals. These wild birds and animals can cause critical damage to the produce. Traditional methods of scaring away birds such as scarecrows are not long-term solutions but short-term solutions. This is a huge problem especially near areas like San Luis Obispo where there are vineyards. Bird damage can be as high as 50% for grapes being grown in vineyards. The total estimated revenue lost annually in the 10 counties in California due to bird and rodent damage to 22 selected crops ranged from $168 million to $504 million (in …

Jester: A Device Abstraction And Data Fusion Api For Skeletal Tracking, Kevin Samuel Schapansky

Master's Theses

Humans naturally interact with the world in three dimensions. Traditionally, personal computers have relied on 2D mice for input because 3D user tracking systems were cumbersome and expensive. Recently, 3D input hardware has become accurate and affordable enough to be marketed to average consumers and integrated into niche applications. Presently, 3D application developers must learn a different API for each device their software will support, and there is no simple way to integrate sensor data if the system has multiple 3D input devices. This thesis presents Jester, a library designed to simplify the development and improve the accuracy of 3D …

ABSTRACT

Oceano Community Health Plan

Phillip Brennan

Recent, mounting research shows that chronic disease, the leading causes of death and primary driver of health care costs, cannot be effectively addressed through education or preventative health alone. A physical environment that promotes health—through access to healthy food, opportunities for physical activity, quality housing, transportation options, and safe schools—is an integral part of making our communities healthier. This research and accompanying Healthy Community Plans will serve as a way for the County to begin looking in-depth at the ways the built environment (our streets, parks, and neighborhoods) contribute or detract from the …


Smarticles: A Method For Identifying And Correcting Instability And Error Caused By Explicit Integration Techniques In Physically Based Simulations, Susan Aileen Marano Jun 2014

Smarticles: A Method For Identifying And Correcting Instability And Error Caused By Explicit Integration Techniques In Physically Based Simulations, Susan Aileen Marano

Master's Theses

Using an explicit integration method in physically based animations has many advantages including conceptual and computational simplicity, however, it re- quires small time steps to ensure low numerical instability. Simulations with large numbers of individually interacting components such as cloth, hair, and fluid models, are limited by the sections of particles most susceptible to error. This results in the need for smaller time steps than required for the majority of the system. These sections can be diverse and dynamic, quickly changing in size and location based on forces in the system. Identifying and handling these trou- blesome sections could allow …


The Role Of Sirtuin Inhibitors On The Proteomic Responses Of The Mussels Mytilus Galloprovincialis And Mytilus Trossulus To Menadione Induced Oxidative Stress, Hayley C. Chilton Jun 2014

The Role Of Sirtuin Inhibitors On The Proteomic Responses Of The Mussels Mytilus Galloprovincialis And Mytilus Trossulus To Menadione Induced Oxidative Stress, Hayley C. Chilton

Master's Theses

Global climate change imposes physiological constraints on marine ecosystems that can alter the distribution of intertidal organisms. In one such instance, the native cold-adapted mussel Mytilus trossulus is being replaced along its southern range by the invasive warm-adapted Mytilus galloprovincialis. These blue mussels occur throughout rocky intertidal zones where they are subjected to greatly varying environmental conditions known to induce oxidative stress. We hypothesize that while under acute stress, related Mytilus congeners undergo a shift in redox potential from NADH-fueled respiratory pathways to pathways producing NADPH as a way to decrease the production of reactive oxygen species (ROS) and …
