Proceedings of the 3rd Interdisciplinary Engineering Design Education Conference, IEDEC 2013 | Year: 2013

Online learning is fast becoming a preferred medium of learning. It is estimated that 6 million college students took at least one online course last year. Online learning in technical education is primarily delivered through pre-recorded videos. We will discuss a virtual learning system in the context of electronics engineering education. This learning system models the circuits as well as the instruments that are typically used in the labs to allow students to carry out the experiments in a virtual environment. We have extended the concept further to allow students to carry out the experiments on the web-browsers and devices of their choice. The simulations themselves are carried out utilizing cloud computing infrastructure such as those provided by Amazon and Microsoft while the use focuses on putting the experiments. © 2013 IEEE.

Capital equipment strategic planning (CESP) is a data-driven method that can be used for evaluating a hospital's existing equipment in light of its business goals and budget to develop an unbiased multiyear plan for replacing aging equipment. The foundation for CESP is a rigorous technology assessment of all clinical equipment items that represent a significant cost to replace (above a certain threshold). Armed with the data gleaned from this technology assessment, hospital executives can begin to make informed decisions about where to allocate capital spending to replace mission-critical clinical equipment.

Pb Zn 2010 - Lead-Zinc 2010 Symposium, Held in Conjunction with COM 2010 | Year: 2010

Quemetco, City of Industry, California, an Eco-Bat battery recycling facility, maintains state of the art emissions control technology producing 100,000+ metric tons of lead/lead alloys primarily from spent lead acid batteries controlling emission streams of the feed dryer, reverberatory and electric arc furnaces, and pyro-metallurgical refinery. In 2008, Quemetco introduced the most advanced air emissions treatment system significantly reducing the already low emissions installing both a regenerative thermal oxidizer (RTO) reducing hydrocarbon emissions, and a wet electrostatic precipitator (WESP) lowering lead, arsenic, cadmium and nickel emissions. Quemetco's accomplishment demonstrates a new maximum available control technology (MACT) for secondary smelters.
