Investigation Of Degradation Effects Due To Gate Stress In Gan-On-Si High Electron Mobility Transistors Through Analysis Of Low Frequency Noise, Michael Curtis Meyer Masuda

Master's Theses

Gallium Nitride (GaN) high electron mobility transistors (HEMT) have superior performance characteristics compared to Silicon (Si) and Gallium Arsenide (GaAs) based transistors. GaN is a wide bandgap semiconductor which allows it to operate at higher breakdown voltages and power. Unlike traditional semiconductor devices, the GaN HEMT channel region is undoped and relies on the piezoelectric effect created at the GaN and Aluminum Gallium Nitride (AlGaN) heterojunction to create a conduction channel in the form of a quantum well known as the two dimensional electron gas (2DEG). Because the GaN HEMTs are undoped, these devices have higher electron mobility crucial for …

Evaluation Of Red Alder Mortality In The Little Creek Watershed Following The 2009 Lockheed Fire, Dylan Robert Theobald

Master's Theses

Five hundred eighty red alder along a 2.16 km portion of the Little Creek riparian zone were assessed for mortality following the 2009 Lockheed Fire near Davenport, California. The study area was divided into burn severity zones and every red alder within the riparian zone was observed and assessed for mortality. Height, diameter at breast height (DBH), and age were collected on selected trees. An estimation of red alder large woody debris (LWD) input to Little Creek since a 2010 LWD survey (Smith, 2010) was calculated using average red alder tree dimensions applied to Smalian’s formula (MLNRO, 2011). The mean …

Classification Of Plot-Level Fire-Caused Tree Mortality In A Redwood Forest Using Digital Orthophotography And Lidar, Brian David Bishop

Master's Theses

Swanton Pacific Ranch is an approximately 1,300 ha working ranch and forest in northern Santa Cruz County, California, managed by California Polytechnic State University, San Luis Obispo (Cal Poly). On August 12, 2009, the Lockheed Fire burned 300 ha of forestland, 51% of the forested area on the property, with variable fire intensity and mortality. This study used existing inventory data from 47 permanent 0.08 ha (1/5 ac) plots to compare the accuracy of classifying mortality resulting from the fire using digital multispectral imagery and LiDAR. The percent mortality of trees at least 25.4 cm (10”) DBH was aggregated to …

The Changing Format For Delivering An Effective Message Using Video And Multimedia In Education, Instruction, And Various Forms Of Communications: A Descriptive Analysis Using Public Relations Theory, Rachael Leigh Burnham

Journalism

ABSTRACT

Given the evolving nature of the forms of mass media in communication, it is imperative to stay up-to-date with the changes that occur in developing platforms of technology, as well as how these advancements are effecting new generations of learners and communicators. Generation Y students have developed a spectrum of learning styles and preferences due to their deep rooted connection to technology that has caused a conflict in learning with traditional, written instruction and communication. No longer do students just want to either read or listen, and video or multimedia platforms can provide them with the resources they may …

Creating Consistency: The Strengthening Of Cal Poly Football’S Brand To Improve Its Fan Base, Katie Ryan

Journalism

Collegiate football is the preeminent sport at most universities and is closely observed by a very dedicated and consistent fan base. At California Polytechnic State University San Luis Obispo, the football program has a very minimal following compared to other Division 1 (both BCS and FCS) schools. Since a strong and passionate fan base is absolutely crucial to maintaining consistently high game day attendance rates, Cal Poly immediately needs to explore avenues to reach out to its publics. This study observes how Cal Poly’s football program could increase attendance and build consistency in their fan base by implementing a proactive …

Toward Directed Energy Planetary Defense, Philip Lubin, Gary B. Hughes, J Bible, Jesse Bublitz, Josh Arriola, Caio Motta, Jon Suen, Isabella Johansson, Jordan Riley, Nilou Sarvian, Deborah Clayton-Warwick, Jane Wu, Andrew Milich, Mitch Oleson, Mark Pryor, Peter Krogen, Miikka Kangas, Hugh O'Neill

Statistics

Asteroids and comets that cross Earth’s orbit pose a credible risk of impact, with potentially severe disturbances to Earth and society. We propose an orbital planetary defense system capable of heating the surface of potentially hazardous objects to the vaporization point as a feasible approach to impact risk mitigation. We call the system DE-STAR, for Directed Energy System for Targeting of Asteroids and exploration. The DESTAR is a modular-phased array of kilowatt class lasers powered by photovoltaics. Modular design allows for incremental development, minimizing risk, and allowing for technological codevelopment. An orbiting structure would be developed in stages. The main …

Paper-Based Standard Addition Assays, Cory A. Chaplan, Haydn T. Mitchell, Andres W. Martinez

Chemistry and Biochemistry

Standard addition assays conducted on paper-based microfluidic devices are introduced as an alternative to external standards for calibrating quantitative tests. To demonstrate this technique, a colorimetric, paper-based, standard addition assay was optimized for the determination of glucose concentrations in the range of 0 to 5 mM. Comparable results were obtained from the assay via digital image colorimetry under three different lighting conditions.

Mechanical And Microscopic Properties Of The Reversible Plastic Regime In A 2d Jammed Material, Nathan C. Keim, Paulo E. Arratia

Physics

At the microscopic level, plastic flow of a jammed, disordered material consists of a series of particle rearrangements that cannot be reversed by subsequent deformation. An infinitesimal deformation of the same material has no rearrangements. Yet between these limits, there may be a self-organized plastic regime with rearrangements, but with no net change upon reversing a deformation. We measure the oscillatory response of a jammed interfacial material, and directly observe rearrangements that couple to bulk stress and dissipate energy, but do not always give rise to global irreversibility.

Calculating Ellipse Overlap Areas, Gary B. Hughes, Mohcine Chraibi

Statistics

We present an approach for finding the overlap area between two ellipses that does not rely on proxy curves. The Gauss-Green formula is used to determine a segment area between two points on an ellipse. Overlap between two ellipses is calculated by combining the areas of appropriate segments and polygons in each ellipse. For four of the ten possible orientations of two ellipses, the method requires numerical determination of transverse intersection points. Approximate intersection points can be determined by solving the two implicit ellipse equations simultaneously. Alternative approaches for finding transverse intersection points are available using tools from algebraic geometry, …
