Political Feasibility Of Implementing Smart Growth Development Strategies In The Monterey Bay Area, Kristin Mckee

Master's Theses

Development over the past sixty years has created patterned growth and expansion outward from city centers, separating residences from commercial areas and employment centers. This separation of land uses has increased automobile dependency, which increases vehicle miles traveled and associated greenhouse gas emissions. California Senate Bill 375 mandates the development and implementation of a “Sustainable Communities Strategy” in order to plan regional land use and transportation in a coordinated fashion. In coordination with this effort, the Association of Monterey Bay Area Governments (AMBAG) is developing the Regional Implementation Plan for Smart Growth Development Strategies, which entails the identification of smart …

The Characterization Of Biofilm Attachment To Metal Interfaces: Effects Of Substratum Properties, Marcel D. Mendes

Master's Theses

Bacteria are among the most abundant microorganisms on earth, and can be found in essentially every environment. When a clean surface is exposed to media containing planktonic bacteria, the bacterial cells will attach to the surface and aggregate to form what is known as a biofilm. Biofilms have been shown to negatively affect many industries including medical, industrial, and food science applications. While biofilms have been well characterized from a microbiology perspective, there has been much less research from a materials science standpoint. It is hypothesized that the material properties of the substratum (such as the micro-structure) have a significant …

Evaluation Of Textural Properties Of Cooked Beef Batters, Lee M. Christensen

Master's Theses

In the meat science industry the primary method used to determine the binding capabilities of a raw material is to reference the binding index created by Carpenter and Saffle (1964). This index is primarily based on the emulsification capabilities of meats and does not consider texture. As texture is one of the principal factors in determining acceptability of foods (Bourne, 1978), a testing method that captures textural attributes of raw materials is essential. This work was developed to capture raw material texture and cooking loss in a relatively quick manner.

Textural properties of cooked beef batters using two different salt …

Wideband, Low-Loss, High-Power Handling Diplexer For Airborne Early Warning (Aew) Systems, Awrang Taiby

Master's Theses

Airborne Early Warning (AEW) systems rely on rotary couplers (RC) to interface rotating antenna elements on aircraft exteriors with stationary onboard systems. The demand for additional channels in new generation AEW systems increases the complexity of rotary couplers significantly. On the other hand, if signals in separate frequency bands use the same channel, existing AEW designs could incorporate additional channels with only minor changes. Passive RF diplexers can accomplish this task. Required characteristics include low-loss (<0.5dB), wideband (4.4:1), and high-power (>6kW) handling capability. Two diplexer candidates are synthesized and characterized with the aid of a commercial circuit simulation package that includes a 3D full-wave …

Getting On The Bus: Marketing San Luis Obispo's Regional Transit Authority, Jenna Higgins

Master's Theses

A new trend is emerging, seeking to recognize the benefits of and encourage the use of public transportation. In the past, public transit agencies have not directed much energy or focus at marketing, seeking to use limited funds elsewhere. “The common perception is that money spent on marketing would be better spent on transit systems themselves…over time, a sustained investment in marketing increases the number of people who use transit. Increased ridership leads to increased revenue, and ideally, an increase in service to match the new demand” (Arpi, 2009).

Even as marketing gains importance in the public transit world, questions …

The Micro Check-In Framework For The Next Generation Of Location-Based Applications, Shraddha Kacha

Master's Theses

Today's mobile computing platforms provide new, convenient possibilities for location-based commercial activity. In particular, the global positioning system (GPS) provides location data for local advertising and retail activity. In this thesis, we take the next step and introduce the concept of micro check-in. Micro check-in is a simple framework that allows users to match their current location to specific objects or places at a resolution much finer than that allowed by GPS based check-in. We show that micro check-in enables customers to reveal their location at a fine level of granularity. By describing the concepts of points of service, service …

Comparing Anti-Vegf Antibodies And Aptamers On Paper Microfluidic-Based Platforms, Katherine Noel Clayton

Master's Theses

The field of microfluidics is expanding into what is known as paper microfluidics. This uses a paper platform rather than materials (i.e. PDMS, PMMA) that are commonly used in microfluidics research. Current devices require an expensive manufacturing process and external sources to power the device. Such devices are not practical in low resource environments. As a consequence, it is the goal of this Thesis to develop a three-dimensional, multiplexed assay chip using nitrocellulose membranes. This device comprises of multiple layers of nitrocellulose membranes with defined fluidic channels. The multiple layers are bound together using double backed tape, and imbedded between …

Development Of A Ground Based Atomic Oxygen And Vacuum Ultraviolet Radiation Simulation Apparatus, Max Jay Glicklin

Master's Theses

The space environment possesses numerous unique and unusual attributes, creating challenges that must be considered in order to accomplish a successful space mission. Two of the detrimental aspects of the space environment include Atomic Oxygen, AO, and Ultraviolet, UV, radiation. UV radiation becomes more severe in space as there is no atmosphere to attenuate incoming photons, thereby exposing spacecraft to radiation that never reaches the surface of the Earth. Overall, space vehicles are exposed to a total of 107.4 Watts/m² of light shorter than 400 nm. AO is created by the photo disassociation of molecular oxygen by UV radiation …

Gpu-Accelerated Point-Based Color Bleeding, Ryan Daniel Schmitt

Master's Theses

Traditional global illumination lighting techniques like Radiosity and Monte Carlo sampling are computationally expensive. This has prompted the development of the Point-Based Color Bleeding (PBCB) algorithm by Pixar in order to approximate complex indirect illumination while meeting the demands of movie production; namely, reduced memory usage, surface shading independent run time, and faster renders than the aforementioned lighting techniques.

The PBCB algorithm works by discretizing a scene’s directly illuminated geometry into a point cloud (surfel) representation. When computing the indirect illumination at a point, the surfels are rasterized onto cube faces surrounding that point, and the constituent pixels are combined …

The aim of this study is to incorporate the spectral, temporal and spatial attributes of a smoke plume for Early Forest Fire Detection. Image processing techniques are used on multispectral (red, green, blue, mid-wave infrared, and long-wave infrared) video to segment and indentify the presence of a smoke plume within a scene.

The temporal and spectral variance of a smoke plume is captured through Principal Component Analysis (PCA) where the Multispectral-Multitemporal PCA is performed on a sequence of video frames simultaneously. The presence of a plume existing in one of the higher order principal components is determined by the texture …

Spectral Shape Division Multiplexing (Ssdm): Apparatus, Transmitter, Receiver And Detection, Fausto Daniel Holguín-Sánchez

Master's Theses

Wireless communication companies require to use the frequency spectrum to operate. Both frequency licenses and infrastructure to reuse frequencies are costly resources subject to increasing demand. This work introduces a novel multiplexing method that saves spectrum called Spectral Shape Division Multiplexing (SSDM). Under certain configurations, SSDM displays higher flexibility and throughput than other spectrally efficient methods.

SSDM defines the structure of a wireless multi-carrier by software. It is similar to Orthogonal Frequency Division Multiplexing (OFDM) in that both use overlapped sub-carriers to make efficient use of allocated spectrum. However, SSDM has several advantages. Where OFDM organizes sub-carriers orthogonally, SSDM allows …
