Design And Analysis Of A Positively Engaged Continuously Variable Transmission, Brandon Levi Haupt Oct 2008

Design And Analysis Of A Positively Engaged Continuously Variable Transmission, Brandon Levi Haupt

Theses and Dissertations

With energy demands at an all time high, mechanical power systems are under great scrutiny. Substantial efforts are being made throughout the world to reduce energy use in common mechanical systems such as the internal combustion engine and transmission system. Eliminating or reducing efficiency losses in the transmission is a potential source of improving the efficiency of the system. To do so, various alternative types of transmissions are being investigated. At Brigham Young University, development of a Positively Engaged Continuously Variable Transmission (PECVT) is progressing. In addition to the efficiency increases that would occur as a result of operating the ...

The Arctic seafloor remains one of the last unexplored areas on Earth. Exploration of this unique environment using standard remotely operated oceanographic tools has been obstructed by the dense Arctic ice cover. In the summer of 2007 the Arctic Gakkel Vents Expedition (AGAVE) was conducted with the express intention of understanding aspects of the marine biology, chemistry and geology associated with hydrothermal venting on the section of the mid-ocean ridge known as the Gakkel Ridge. Unlike previous research expeditions to the Arctic the focus was on high resolution imaging and sampling of the deep seafloor. To accomplish our goals we ...


Preparation And Accreditation Of Level 7 Engineering Programmes, Mark Mcgrath Jan 2008

Preparation And Accreditation Of Level 7 Engineering Programmes, Mark Mcgrath

Conference Papers

Accreditation of 3rd level educational programmes by a suitably recognised professional body is of particular relevance in relation to engineering. The completion of a sequence of modules which leads to the attainment of this professionally recognised award is viewed as integral to the undertaking. The engineering technology fields are developing and expanding rapidly and the third level sector must keep abreast of these changes. This is essential if the third level institutions wish to continue delivering programmes which produce graduates who can successfully complete the transition from 3rd. Level to the various engineering sectors.

This paper outlines various aspects ...


Applications Of Narrative To The Engineering Decision Making Process And The Pedagogy Of Engineering Education, Todd Chaney Dusold Jan 2008

Applications Of Narrative To The Engineering Decision Making Process And The Pedagogy Of Engineering Education, Todd Chaney Dusold

Graduate Theses and Dissertations

Narrative is defined as a basic form of human communication. It is through narrative that humans experience and comprehend life. Using narrative as a tool to improve communication and comprehension requires incorporating several components into a complete narrative structure. The components of a narrative consist of a story; that is, a sequence of events providing chronological order and context to a subject, and a method of discourse; that is, the means in which the story is told. Creating narrative allows for increased cognitive understanding of a subject because it is the way in which we as humans naturally communicate. This ...

This poster reports on the August 2007 Black Sea Expedition of the Institute for Archaeological Oceanography at the University of Rhode Island (IAO) and the Institute for Exploration (IFE), in collaboration with the Department of the Underwater Heritage of Ukraine. This year’s work marks a new phase in a multi-year (2000–2012) archaeological and oceanographic survey of the Black Sea. 2007 fieldwork focuses on two Byzantine shipwrecks. The 10th century C.E. shipwreck Chersonesos A (discovered in 2006) lies at 140 m depth in the suboxic zone off the Crimean peninsula. The ship carried a cargo of one-handled jars ...
