Between 20% to 50% of industrial energy input is lost as waste heat in the form of hot exhaust gases, cooling water and energy loss from generating equipment. Vibrations and variable heating are a common form of waste energy in motors, generators, power cables exposed to ambient temperatures, fuel exhausts from vehicles, and various types of heavy machinery. The recovery of even a fraction of this lost energy would have a transformational impact on the utility industry since the demand for energy is increasing and the impact of this demand on the environment is significant. Recent technical breakthroughs in new …

Electrospinning is a widely applicable technique that generates non-woven fibers in the micro and nano range. In this project two of its applications are highlighted namely filtration media and enhancement of wettability. The first project demonstrates that electrospinning can be used to produce new fiber filtration media with controlled microstructure. The bimodal and unimodal orthogonal and random filters were made and characterized against their filtration efficiency and pressure drop. Figure of Merit (FOM) was also calculated and discussed. It is shown that the FOM increases when the electrospun fibers are arranged into alternating layers of aligned course and fine fibers. …

Theses and Dissertations
This thesis explores the creation and setup of a prototype that allows users of the device to interact within an indoor real world environment and a virtual environment simultaneously using high-tech common technology. The prototype is comprised of a small mobile device such as a cellular mobile phone, Raspberry Pi computer, a battery powered handheld Pico projector, and software developed for the Android OS. The software can easily be ported to other mobile and non-mobile operating systems. The mobile device must contain accelerometer, magnetometer, and gyroscope embedded sensors as well as 802.11 wireless network chip. The prototype software implements an …
