Application Of Volterra Functions To X-31 Aircraft Model Motion, United States Air Force Academy, Russell M. Cummings

Aerospace Engineering

Recent advances towards an efficient computational method for accurately determining the stability and control characteristics of an aircraft are discussed and critiqued. The present approach with greatest promise is to reduce the number of high-fidelity CFD simulations by using Volterra functions Reduced Order Modeling. This type of reduced order model is a predictive model which has a unique training maneuver -a unit impulse. The advantage of such an approach is the fast prediction of the aerodynamic characteristics of an aircraft. This article presents the results of application of the Volterra functions ROM for prediction of linear movement of a 2D …

Teaching Architects And Engineers: Up And Down The Taxonomy, Edmond P. Saliklis, Robert Arens, Joseph Hanus

Architectural Engineering

Engineering faculty and Architecture faculty both address student learning through the prism of Bloom’s taxonomy of the cognitive domain, but do so in diametrically opposite manners. Engineering faculty tend to assess student learning starting at the lowest taxonomy level, Acquisition of Knowledge, and progress in their curriculum and courses to the higher levels of Synthesis and Evaluation. Compare this to a studio environment in an undergraduate Architecture curriculum, where the faculty often begin with the highest levels, such as Evaluation in applying value judgments about the adequacy of the design and Synthesis, by putting disparate pieces of …

Purple Martin, Progne Subis, In San Luis Obispo County Riparian Habitat: Presence, Persistence, Nesting, Brooding And Reproductive Success, Shannon Eileen Murphy

Biological Sciences

The State of California, as of 2002, identified the Purple Martin as a bird species of Special Concern (Airola et al., 2003). These migrants were historically found in a unique habitat in Central California; nesting in natural cavities of Western Sycamores within Riparian Habitats. I am proposing that Purple Martins still successfully nest and brood young in this unique habitat in San Luis Obispo County. The primary study site is in Atascadero where Highway 41 meets San Gabriel Road and San Gabriel Road crosses Atascadero creek. The secondary site is Highway 58 in Santa Margarita where the highway crosses the …

The Effect Of Particle Surface Area To Volume Ratio On Ion Release From Cocr Spheres, Darin J. Grandfield

Master's Theses

In 2005, over 200,000 Americans underwent a hip arthroplasty, the replacement of a hip joint with an artificial prosthesis. Of these arthroplasties, metal-on-metal type implants represent an increasing usage percentage. Metal-on-metal implants are selected largely for their low volumetric wear rate, durability, and resistance to corrosion. In spite of these advantages, little is known concerning the long-term consequences of heavy metal alloy use in the body, although early research indicates potentially carcinogenic results. This thesis is a preliminary investigation into these long term effects and their root causes.

An improved comprehension of the corrosion kinetics and the rate of ion …

Evaluating The Electrical Response Of Polyaniline To Mechanical Strain, Matthew L. Goebel

Master's Theses

This thesis focuses on the electrical output of polyaniline films subjected to uniaxial strain in hydrochloric acid solutions. Polyaniline belongs to novel class of materials known as conducting polymers. Alternating single and double bonds in the backbone of conducting polymers allow them to transmit electric charge when they are doped with negatively charged ions. Modifying the degree of doping and other electrical/chemical treatments allow conducting polymers to exhibit conducting, semi-conducting, or insulating electrical properties. Resilient mechanical properties, good processability, and low cost make conducting polymers good candidates for applications traditionally held by metals and semi-conductors.

When tensile strain is applied …

Biology Of Ultramafic Rocks And Soils: Research Goals For The Future, Robert S. Boyd, Arthur R. Kruckeberg, Nishanta Rajakaruna

Biological Sciences

In absence of a text abstract the introduction of the article is provided.

Introduction

At this, the 6th International Conference on Serpentine Ecology, it seems timely to review briefl y the present status of the fi eld and to project the needs for future research. Although a great deal of serpentine research was done prior to 1960, as summarized by Krause (1958) and discussed briefl y by Brooks (1987), much of our progress in learning how serpentine geology affects plant and animal life occurred in the mid- to late 20th century. In that era, it was the landmark studies of …

Phylogeography Of The North American Red Fox: Vicariance In Pleistocene Forest Refugia, Keith B. Aubry, Mark J. Statham, Benjamin N. Sacks, John D. Perrine, Samantha M. Wisely

Biological Sciences

Fossil, archaeological, and morphometric data suggest that indigenous red foxes in North America were derived from vicariance in two disjunct refugia during the last glaciation: one in Beringia and one in the contiguous USA. To test this hypothesis, we conducted a phylogeographical analysis of the North American red fox within its presettlement range. We sequenced portions of the mitochondrial cytochrome b (354 bp) gene and D-loop (342 bp) from 220 historical red fox specimens. Phylogenetic analysis of the cytochrome b gene produced two clades that diverged c. 400 000 years before present (bp): a Holarctic and a Nearctic clade. …

Adiantum Viridimontanum, Aspidotis Densa, Minuartia Marcescens, And Symphyotrichum Rhiannon: Additional Serpentine Endemics From Eastern North America, Tanner Harris, Nishanta Rajakaruna

Biological Sciences

Serpentine outcrops around the world are known to harbor disproportionately high rates of plant endemism. Remarkable cases of serpentine endemism occur in New Caledonia and Cuba, with 3178 and 920 endemic taxa, respectively, found solely on serpentine. Despite the patchy occurrence of serpentine in eastern North America from Québec and Newfoundland south to Alabama, only one taxon, Cerastium velutinum var. villosissimum, has been broadly recognized as a serpentine endemic for the region. Based on reports in the literature, we suggest that Adiantum viridimontanum, Minuartia marcescens, and Symphyotrichum rhiannon be considered endemic to serpentine soils from the east coast …

Advances In Serpentine Geoecology: A Retrospective, Nishanta Rajakaruna, Robert S. Boyd

Biological Sciences

(In absence of a text abstract the first paragraph of the paper is provided.)

Serpentine habitats have long provided model settings for geoecological research (reviewed in Alexander et al. 2007, Brady et al. 2005, Brooks 1987, Kazakou et al. 2008, Kruckeberg 1984, Proctor and Woodell 1975, Raja-karuna et al 2009). Serpentine loosely refers to a broad group of minerals associated with the weathering of ultramafi c (high iron and magnesium-rich) rocks found along continental margins and orogenic belts. Soils associated with such rocks often differ from more widespread soils, being less fertile and having high concentrations of some heavy metals. …

Does Student Leadership Participation Enhance The Development Of Emotional Intelligence, Michelle Breanne Curro

Master's Theses

Emotional Intelligence is believed to explain how emotions may be used, monitored, and measured to predict workplace success and failure, the suggestion that if individuals can balance the emotions within themselves and others, they can use their skills to better their organization. This study explored the development of Emotional Intelligence in the ASI Student Manager Team in comparison to Student Government members at California Polytechnic State University, San Luis Obispo (Cal Poly) during the fall 2008 quarter. The Bar-On Emotional Quotient Inventory (EQ-i) was used to assess student leaders’ Emotional Intelligence (EI) development (N = 27). A two sample t-test …

Time-Frequency Analysis Of Intracardiac Electrogram, Erik Brockman

Master's Theses

The Cardiac Rhythm Management Division of St. Jude Medical specializes in the development of implantable cardioverter defibrillators that improve the quality of life for patients diagnosed with a variety of cardiac arrhythmias, especially for patients prone to sudden cardiac death. With the goal to improve detection of cardiac arrhythmias, this study explored the value in time-frequency analysis of intracardiac electrogram in four steps. The first two steps characterized, in the frequency domain, the waveforms that construct the cardiac cycle. The third step developed a new algorithm that putatively provides the least computationally expensive way to identifying cardiac waveforms in the …
