How Autonomous Vehicles Will Reshape The Urban Landscape, Ian R. Mccarville

City and Regional Planning

Autonomous vehicles (AVs) will bring one of the largest revolutions to the nation’s transportation system, with major changes in planning policies and the urban environment. While AVs have already been introduced to our mobility network, they still require a human operator behind the wheel. In coming years, as AV technology becomes more sophisticated, it will begin to dominate the roadways due to the technologies ability to maneuver at a much high accuracy and predictability than human drivers. This transition into an AV oriented future will promote road safety, increase productivity, reduce travel and labor costs, and reinvent the urban landscape.

Relevance Analysis For Document Retrieval, Eric Labouve

Master's Theses

Document retrieval systems recover documents from a dataset and order them according to their perceived relevance to a user’s search query. This is a difficult task for machines to accomplish because there exists a semantic gap between the meaning of the terms in a user’s literal query and a user’s true intentions. Even with this ambiguity that arises with a lack of context, users still expect that the set of documents returned by a search engine is both highly relevant to their query and properly ordered. The focus of this thesis is on document retrieval systems that explore methods of …

Pressure Cylinder Controlled Release Valve, Alexa Dominique Balbuena

Biomedical Engineering

This project aims to integrate an automatic gas release system in a pre-existing scaffold fabrication process for tissue engineering applications.

To form the proper scaffold structure, the fabrication process is heavily influenced by the change in its surrounding pressure. The current production involves a pressure transducer and electric valve that is managed manually to create a suitable pressure environment for the scaffold. This method, although functional, proves to be ineffective when creating several batches; the user needs to constantly monitor the developing pressure profile and alter voltage parameters accordingly to create a linear gas release under a predetermined slope.

Investigation Of Design, Manufacture, Analysis, And Test Of A Composite Connecting Rod Under Compression, Thomas Juhl Rohrbach

Master's Theses

Composite materials hold great potential for the replacement of traditional materials in machines utilized on a daily basis. One such example is within an engine block assembly where massive components inherently reduce the efficiency of the system they constitute. By replacing metal elements such as connecting rods, cylinder caps, or a crank shaft with composite alternatives, a significant increase in performance may be achieved with respect to mechanical strength, thermal stability, and durability, while also reducing mass. Exploration of this technology applied to a connecting rod geometry was investigated through a combination of process development, manufacturing, numerical analysis and testing. …

Optimization Of An Injection Locked Laser System For Cold Neutral Atom Traps, Elliot M. Lehman

Physics

Many types of quantum systems are being explored for use in quantum computers. One type of quantum system that shows promise for quantum computing is trapped neutral atoms. They have long coherence times, since they have multiple stable ground states and have minimal coupling with other atoms and their environment, and they can be trapped in arrays, making them individu- ally addressable. Once trapped, they can be initialized and operated on using laser pulses. This experiment utilizes a pinhole diffraction pattern, which can trap atoms in both bright and dark areas. To maximize trap strength, an injection-locked laser amplification system …
