Poly Canyon Bridge House- Damage Detection Using Forced Vibration Testing, William Rosenblatt, Joshua Raney, Alec Zavala

Baker/Koob Endowments Awarded Projects

Existing methods of evaluating buildings after a seismic event rely on destruction of architectural elements such as cladding, partitions, and ceilings in order to inspect structural members. Evaluations are done by visual inspection with no quantitative data. Current faculty and student research focuses on the application of Forced Vibration Testing (FVT) for assessment of buildings after a seismic event. This nondestructive method involves temporary instrumentation to record building behavior. The Bridge House, located in Poly Canyon, is a structure with removable braces that simulate structural damage. This proposed research will use FVT to investigate damage detection in the Bridge House …

Reducing Transonic Wind Tunnel Sting Interference Effects For Concealed Store Release Testing, Graham Doig, Goran Bogdan, Kaveh R. Kabir, Murray R. Snyder

Aerospace Engineering

Internal weapons bays are becoming increasingly common on aircraft for reasons of stealth and aerodynamic performance, and will be even more prevalent on coming generations of unmanned combat aerial vehicles (UCAVs). Wind tunnel testing of store releases to assess forces and moments for safety and clearance must be conducted with a store mounted to an angled strut rather than a conventional rear sting, to allow the full range of motion as the store “drops” from inside the aircraft. Interference from this strut can disrupt the flowfields and thus the reliability of moments obtained, and therefore an investigation was conducted to …

An Invasive Grass And A Desert Adapted Rodent: Is There An Effect On Locomotory Performance And Is It Modified By Prior Experience Or Familiarization?, Camille D. Boag

Master's Theses

Kangaroo rats (Dipodomys spp.) are frequently characterized as keystone species for their role in altering soil characteristics, changing habitat structure through seed consumption and dispersal, and being important primary consumers in their ecosystem. They are arid adapted and known to forage in areas with sparse vegetation. Studies suggests densely vegetated habitat to be unsuitable for kangaroo rats because plants are an impediment to their locomotion and predator avoidance behaviors. This study focuses on an invasive grass, South African Veldt (Ehrharta calycina), that converts landscapes with sparse vegetation into dense grassland habitats, and the Lompoc kangaroo rat …

Axisymmetric Bi-Propellant Air Augmented Rocket Testing With Annular Cavity Mixing Enhancement, Allen A. C. Capatina

Master's Theses

Performance characterization was undertaken for an air augmented rocket mixing duct with annular cavity configurations intended to produce thrust augmentation. Three mixing duct geometries and a fully annular cavity at the exit of the nozzle were tested to enable thrust comparisons. The rocket engine used liquid ethanol and gaseous oxygen, and was instrumented with sensors to output total thrust, mixing duct thrust, combustion chamber pressure, and propellant differential pressures across Venturi flow measurement tubes.

The rocket engine was tested to thrust maximum, with three different mixing ducts, three major combustion pressure sets, and a nozzle exit plane annular cavity (a …

Quantification Of Blood Flow Velocity Using Color Sensing, Aditya Deepak Sanghani

Master's Theses

Blood flow velocity is an important parameter that can give information on several pathologies including atherosclerosis, glaucoma, Raynaud’s phenomenon, and ischemic stroke [2,5,6,10]. Present techniques of measuring blood flow velocity involve expensive procedures such as Doppler echocardiography, Doppler ultrasound, and magnetic resonance imaging [11,12]. They cost from $8500-$20000. It is desired to find a low-cost yet equally effective solution for measuring blood flow velocity. This thesis has a goal of creating a proof of concept device for measuring blood flow velocity.

Finger blood flow velocity is investigated in this project. The close proximity to the skin of the finger’s arteries …

Seeing What Others Miss: A Study Of Women Entrepreneurs In High-Growth Startups, Stern Neill, Lynn E. Metcalf, Jonathan L. York

Marketing

A pressing question in entrepreneurial research is where opportunities come from. Prior research indicates that some opportunities stem from known parameters and outcomes; some are discovered through engagement with unknown but knowable factors; and others are unknowable until brought into being through a creative process. This paper explores the second and more prevailing view in entrepreneurial research – that individuals discover business opportunity – and examines how high-growth entrepreneurs perceive opportunity through engagement with the world. Survey results, based on responses from 165 women entrepreneurs in high-growth startups, indicate that individuals with a strong discover mindset act and think in …

Effects Of Supplemental Hydration On Physiology And Behavior Of Northern Pacific Rattlesnakes (Crotalus Oreganus Oreganus), Griffin D. Capehart

Master's Theses

Hydration is a critical element for many physiological processes in vertebrates, such as protein production, innate immunity, and behavioral processes such as daily activity and thermoregulation. Few studies have directly assessed the effect of hydration on these animals in nature. While it seems intuitive that drought is stressful to animals, studies examining drought are typically observational and fail to assess how the hydration state of these animals influences their physiology and behavior. We tested for an effect of hydration on several physiological and behavioral parameters in Northern Pacific rattlesnakes (Crotalus oreganus oreganus) by experimentally manipulating hydration levels in …

Wild-But-Not-Too-Wild Animals: Challenging Goldilocks Standards In Rewilding, Erica Von Essen, Michael P. Allen

Between the Species

Rewilding is positioned as ‘post’-conservation through its emphasis on unleashing the autonomy of natural processes. In this paper, we argue that the autonomy of nature rhetoric in rewilding is challenged by human interventions. Instead of joining critique toward the ‘managed wilderness’ approach of rewilding, however, we examine the injustices this entails for keystone species. Reintroduction case studies demonstrate how arbitrary standards for wildness are imposed on these animals as they do their assigned duty to rehabilitate ecosystems. These ‘Goldilocks’ standards are predicated on aesthetic values that sanction interventions inconsistent with the premise of animal sovereignty. These include culling, relocations and …

Distributed Yielding Concept For Improved Seismic Collapse Performance Of Rigid Wall-Flexible Diaphragm Buildings, Maria Koliou, Andre Filiatrault, Dominic J. Kelly, John W. Lawson

Architectural Engineering

Rigid wall-flexible diaphragm (RWFD) buildings are a common type of single-story construction in North America, Europe, and New Zealand that incorporate rigid in-plane concrete or masonry walls and flexible in-plane wood, steel, or hybrid roof diaphragms. RWFD buildings have shown poor seismic performance during past earthquake events. In particular, it has been observed that the global seismic response is dominated by the response of the diaphragm, which is mainly attributed to large in-plane diaphragm displacements that significantly exceed the displacements of in-plane walls. In this study, the concept of distributed yielding in the flexible diaphragm by weakening certain intermediate diaphragm …

Animal Experimentation As A Form Of Rescue, Alexander Zambrano Mr.

Between the Species

In this paper I explore a new approach to the ethics of animal experimentation by conceiving of it as a form of rescue. The notion of rescue, I suggest, involves some moral agent(s) performing an action or series of actions, whose end is to prevent or alleviate serious harm to another party, harm that otherwise would have occurred or would have continued to occur, had that moral agent not intervened. Animal experiments that are utilized as a means to alleviate human illnesses mirror the structure of rescue cases and this means that we can and should apply principles of rescue …

The Effects Of Simplifications On Isolated Wheel Aerodynamics, Sammy Diasinos, Tracie Barber, Graham Doig

Aerospace Engineering

In order to study the aerodynamic forces and flow features of rotating wheels, compromises and simplifications are often made in wind tunnel testing, and more frequently so in numerical modelling. A CFD approach similar to that commonly used in industry was utilised to investigate common assumptions involving; the influence of geometric fidelity in wheel hub regions, ground representation, the modelling of the contact patch, and the effects of rotation on separation. It was found that the separation and wake characteristics were strongly influenced by the rotation of the wheel; the separation point changed by as much as 90% compared to …

Temperatures Experienced By Fresh-Cut Leafy Greens During Retail Storage And Display, W. Brown, E. Ryser, L. Gorman, Scott J. Steinmaus, Keith Vorst

Biological Sciences

There has been limited published work in the United States on temperature profiling of fresh-cut, bagged leafy greens during their transport, retail storage, and retail display. This study utilized temperature monitors placed in backrooms and display cases at nine supermarkets located in southern California: the Central Coast (Santa Barbara to Los Osos), Greater Los Angeles (Burbank area), and Greater Palm Desert. Sensors were installed midway along each 8-foot display case section containing fresh-cut leafy greens. Monitors were placed at the front and back of shelves and in the lower bin. In storage rooms, sensors were placed 4 feet from the …

Implications Of Variable Waste Placement Conditions For Msw Landfills, Jason T. Cox, Nazli Yesiller, James L. Hanson

Civil and Environmental Engineering

This investigation was conducted to evaluate the influence of waste placement practices on the engineering response of municipal solid waste (MSW) landfills. Waste placement conditions were varied by moisture addition to the wastes at the time of disposal. Tests were conducted at a California landfill in test plots (residential component of incoming wastes) and full-scale active face (all incoming wastes including residential, commercial, and self-delivered components). The short-term effects of moisture addition were assessed by investigating compaction characteristics and moisture distribution and the long-term effects by estimating settlement characteristics of the variably placed wastes. In addition, effects on engineering properties …

Design Of High-Area-Ratio Nozzle Contours Using Circular Arcs, K. Schomberg, J. Olsen, Graham Doig

Aerospace Engineering

A method using circular arcs to generate the divergence contour in a supersonic nozzle is presented. Comparison of the arc-based geometry with existing nozzle contours demonstrated that an average decrease in axial length of 7.5% can be expected when the arc-based design method is applied to a core stage nozzle. Two arc-based and conventional nozzles were evaluated numerically across the pressure operating range of a core stage engine to compare calculated thrust and separation characteristics with existing data. The length-weighted thrust coefficient was increased by 0.3–1.8% in the arc-based design in both configurations. Separated flow characteristics were compared using contours …

Orbital Simulations On The Deflection Of Near Earth Objects By Directed Energy, Qicheng Zhang, Kevin J. Walsh, Carl Melis, Gary Hughes, Philip Lubin

Statistics

Laser ablation of a Near Earth Object (NEO) on a collision course with Earth produces a cloud of ejecta which exerts a thrust on the asteroid, deflecting it from its original trajectory. The DE-STAR system provides such a thrust by illuminating an Earth-targeting asteroid or comet from afar with a stand-off system consisting of a large phased-array laser in Earth orbit. A much smaller version of the same system called DE-STARLITE travels alongside the target, operating in a stand-on mode, slowly deflecting it over a long period. Such a stand-on system would also permit directing the thrust in any desired …

Creation And Analysis Of Checklists To Improve Raquet Stringing Performance In Tennis Warehouse, Alston S. Nguyen

Industrial and Manufacturing Engineering

Tennis Warehouse has a need to increase the supply of strung racquets and man hours to complete these strung racquets over the course of a year. That is, the demand can be increased by up to 4 times its average load during certain hectic parts of the year (professional tournaments, holidays, and competitive seasons). Not meeting this demand can lead to upset customers, unnecessary waste and replacing of rushed items and shipping costs, and a discouraged customer service representative workforce. The objective of this project is to use a set of checklists to address this problem and attempt to increase …
