Current Protection For The Energy Harvesting From Exercise Machines (Ehfem) Project, Colton Crivelli

Electrical Engineering

The Energy Harvesting from Exercise Machines (EHFEM) project intends to create an exercise machine that recycles the energy expended by an athlete operating the machine by sending it to the electric grid. The work done by the user goes through a DC-DC converter and an inverter in order to prepare it for delivery to the grid. A protection circuit ensures that the inverter does not try to pull too much current from the DC-DC converter. The project implements a current protection system that ensures the system doesn’t experience an overcurrent condition.

The Smart Growth Implications Of The Los Angeles Adaptive Reuse Ordinance, Forrest F. Chamberlain

Master's Theses

The Los Angeles Adaptive Reuse Ordinance (ARO) is an incentive program that encourages building reuse through regulatory exemptions. The ARO was partially intended to reduce vehicle miles travelled by encouraging mixed commercial and residential uses in existing buildings within Downtown Los Angeles and areas poised for redevelopment (Mayor’s Office of Economic Development, 2004, pp. 22, 51). Researchers and planners claim that the ARO helped to reduce vehicle miles travelled (Bell, 2014; Los Angeles Department of City Planning, 2014d; Bullen & Love, 2009; Bernstein, 2012), but these claims are not supported by discussions of the spatial distribution of ARO projects in …

Guidelines For Sustainable Urban Zero Pollution Community (S.U.Z.C), Mianda Khaled Khattab

Theses and Dissertations

The concept of sustainability has been introduced in the 1980s with the focus of environmental protection, where many developed and developing countries were and still are aiming to reach sustainability. Yet, with the increase of urbanization level, the tendency to meet the needs of the rising population is increasing without the focus of the environmental resources that are being abused in return. This leads to increasing the gap and the greed within the community between the rich people who can afford to abuse resources and the poor who can barely access their daily needs. This gap is concluded in an …
