Implementation Of A Conrad Probe On A Boundary Layer Measurement System, Charles Rocky Ulk
Master's Theses
This thesis presents the design, calibration, and performance evaluation of a type of two-hole pressure probe anemometer known as a Conrad probe, as well as its subsequent implementation on an autonomous, compact boundary layer measurement device and its first application for subsonic in-flight measurements of a swept wing boundary layer. Calibration of the Conrad probe was accomplished using two calibration functions and a non-nulling method for resolving in-plane flow velocity direction and magnitude over a range of ±30 degrees. This approach to calibration and application offered the advantages of rapid data acquisition with lower energy consumption than alternative methods for …
Medtronic Universal Crimping Machine,

Medtronic Universal Crimping Machine, Justin Ginochio, Andrew Hanson, Zachary (Zach) Dieterle
Mechanical Engineering
This project is geared towards the redesign and implementation of a crimping tool for use in the manufacturing of catheters produced by Medtronic Inc. Catheters require two steering cables to maneuver the end of the catheter through the body. The steering cables have a sleeve that is crimped onto their end in order to hold the cable in place inside the catheter steering handle. The current crimping tool, designed by Astro Tool Corp, has a few problems associated with its design. Additionally we are trying to get rid of a step in the manufacturing process that involves the adhesive, cyanoacrylate, …
Guidable Motorcycle Headlight,

Guidable Motorcycle Headlight, Billie B. Fritz, Toby J. Lloyd
Mechanical Engineering
Motorcycling at night is an inherently dangerous situation and is compounded by poor illumination of the roadway when cornering through a turn. Due to stationary headlamps geometry being designed for upright riding position, cornering a motorcycle causes the illumination of the forward path to be decreased significantly. The goal of this project is to develop a lighting system that will improve road illumination for riders at night using guidable lights that deflect prior to and during a turn. In addition to developing a working prototype, this project’s intent is to work in conjunction with a partner from the school of …
Evaluation Of Quasi-Static Indentation Damage In Aluminum Honeycomb Core - Graphite/Epoxy Sandwich Structures,

Evaluation Of Quasi-Static Indentation Damage In Aluminum Honeycomb Core - Graphite/Epoxy Sandwich Structures, David Eisenberg
Renée Crown University Honors Thesis Projects - All
Sandwich composites utilize a low density core and relatively stiff face sheets. These structures are ideal for applications that require high compressive strength, high bending stiffness, and very low weight such as aerospace vehicles. However, one problem with sandwich composites is their susceptibility to low velocity impact damage. Low velocity impacts result in both external damage, in the form of dents, and internal damage, in the form of core crushing, face sheet delaminations (two adjacent plies separating from one another), fiber fractures and matrix cracks. In general, it is assumed that visibly evident damage will be repaired. Barely visible impact …

Marine Current Energy Devices: Current Status And Possible Future Applications In Ireland, Fergal O'Rourke, Fergal Boyle, Anthony Reynolds

There is a growing demand for the use of renewable energy technologies to generate electricity due to concerns over climate change. The oceans provide a huge potential resource of energy. Energy extraction using marine current energy devices (MCEDs) offers a sustainable alternative to conventional sources and a predictable alternative to other renewable energy technologies. A MCED utilises the kinetic energy of the tides as opposed to the potential energy which is utilised by a tidal barrage. Over the past decade MCEDs have become an increasingly popular method of energy extraction. However, marine current energy technology is still not economically viable …

Increasing The Sensitivity Of Surface Acoustic Wave (Saw) Chemical Sensors And Other Chemical Sensing Investigations, Nina R. Smith
Theses and Dissertations
The work involves the fabrication and testing of three different surface acoustic wave (SAW) device designs, an investigation of nanowires sensitive to chemicals and preconcentrator prototypes to include with chemical sensors. The SAW chemical sensor designs include modifications to a basic SAW device to see if the sensitivity of the SAW device is increased. The modifications consist of etched trenches along the propagation field, coating the device with carbon nanotubes (CNTs) under the chemically sensitive layer and coating CNTs on top of the chemically sensitive layer. SAW devices are coated with Nafion®, a polymer sensitive to ethanol. The tests indicate …
Investigation Of Thermal Management And Metamaterials,

Investigation Of Thermal Management And Metamaterials, Calvin T. Roman
Theses and Dissertations
Thermal metamaterials are materials composed of engineered, microscopic structures that exhibit unique thermal performance characteristics based primarily on their physical structures and patterning, rather than just their chemical composition or bulk material properties. The heat transfer performance attributes of a thermal metamaterial are such that similar performance cannot be obtained using conventional materials or compounds. Thermal metamaterials are an emerging technology, and are just now beginning to be acknowledged and developed by the microelectronics and material sciences community. This thesis effort analyzed the current state of thermal metamaterial research, examined the physics and theory of heat transfer and electrical conductivity …
Bidirectional Electrowetting Actuation With Voltage Polarity Dependence,

Bidirectional Electrowetting Actuation With Voltage Polarity Dependence, Nathan B. Crane, Alex A. Volinsky, Pradeep Mishra, Ajay Rajgadkar, Mehdi Khodayari
Faculty Publications
This work presents an electrowetting system in which the actuation direction depends on the polarity of the applied voltage. Since electrowetting response depends on the voltage squared, it is typically independent of voltage sign to first order. However, the introduction of an electrochemicaal diode into the equivalent electrical circuit permits polarity-dependent behavior. Electrochemical diodes were created by making holes in the dielectric. The aluminum electrodes passivate and prevent current flow in one direction, creating diode-like behavior with high breakdown voltage. The resulting actuation forces were directly measured and are of comparable magnitude for both actuation directions.

A critical element to the success of new propulsion technologies that enable reductions in fuel use is the integration of component thermal management technologies within a viable vehicle package. Vehicle operation requires vehicle thermal management systems capable of balancing the needs of multiple vehicle systems that may require heat for operation, require cooling to reject heat, or require operation within specified temperature ranges. As vehicle propulsion transitions away from a single form of vehicle propulsion based solely on conventional internal combustion engines (ICEs) toward a wider array of choices including more electrically dominant systems such as plug-in hybrid electric vehicles …

Electrifying transportation can reduce or eliminate dependence on foreign fuels, emission of green house gases, and emission of pollutants. One challenge is finding a pathway for vehicles that gains wide market acceptance to achieve a meaningful benefit. This paper evaluates several approaches aimed at making plug-in electric vehicles (EV) and plug-in hybrid electric vehicles (PHEVs) cost-effective including opportunity charging, replacing the battery over the vehicle life, improving battery life, reducing battery cost, and providing electric power directly to the vehicle during a portion of its travel. Many combinations of PHEV electric range and battery power are included. For each case, …
