The Development And Fabrication Of A Modular Vertical Reciprocating Conveyor System For The Transportation Of Materials To And From A Mezzanine., Matthew Paul Crum

Electronic Theses and Dissertations

The purpose of this developmental project was to design and fabricate a vertical reciprocating conveyor in order to eliminate the process of manually carrying 27 pound containers of plastic resin up and down a flight of offset space saver stairs. This project took place and was built for Phoenix Closures Incorporated. The conveyor was designed and built in house because there are no commercially available vertical reciprocating conveyors available that meet the necessary requirements.

The capabilities of the proposed vertical reciprocating conveyor are not limited to the carrying of the containers but designed to carry vacuum cleaners, tool boxes, and …

Innovative Design: Design Of A Press System And Molds To Produce A Skateboard Deck., George William Linke

Electronic Theses and Dissertations

Skateboarding is a passion for many people. Homemade skateboard machinery has been fabricated throughout the country. While the demand for skateboards is steady; there is a steady growth in the homemade skateboard deck market. The desire to create a one of a kind deck that expresses a person's individualism is growing. This applied research and development effort - designing and fabricating a fluid powered press system and 2-part mold assembly for forming glue up laminations for skateboard decks - is an attempt to gain understanding of the different phases of the product design process.

New Test Set For Video Quality Benchmarking, Joaquin Raventos

Electronic Theses and Dissertations

A new test set design and benchmarking approach (US Patent pending) allows a "standard observer" to assess the end-to-end image quality characteristics of video imaging systems operating in day time or low-light conditions.

It uses randomized targets based on extensive application of Photometry, Geometrical Optics, and Digital Media.

The benchmarking takes into account the target’s contrast sensitivity, its color characteristics, and several aspects of human vision such as visual acuity and dynamic response. The standard observer is part of the "extended video imaging system" (EVIS).

The new test set allows image quality benchmarking by a panel of standard observers at …

Wired For Business: The Roebling Story., Kelley Marie Hatch-Draper

Electronic Theses and Dissertations

John Augustus Roebling, a classically educated civil engineer and young Hegelian, immigrated to America in 1831 in search of freedom from a repressive political system that afforded him no opportunity for advancement. Arriving in the midst of the American market revolution, his dream of establishing an agrarian farming colony changed in response to societal transformations resulting from mechanization and the rise of industry. Within forty years, Roebling achieved fame as a canal engineer and bridge designer while establishing the American wire rope industry. Without Roebling's innovation in wire-rope, modern suspension bridges, high-rise elevators, construction cranes, and cable cars would not …
