Public transit systems are expanding in the majority of cities in the United States due to the increasing numbers of people who use public transportation as their main commute facility. Evaluating the efficiency of public transit systems results in providing better services for the residents on one hand and reduces the unnecessary costs on the other hand.
In this research, the efficiencies of bus routes options in County are evaluated. After reviewing different literature, Fuzzy AHP …

Theses and Dissertations
The opportunities for both power density and efficiency improvements of photovoltaic (PV) inverter have come with the development of commercially available wide bandgap (WBG) devices such as Gallium Nitride (GaN), and Silicon Carbide (SiC).
In this thesis, how the replacement of Silicon (Si) Insulated Gate Bipolar Transistor (IGBT), with SiC Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) affects the power density and efficiency of a solar inverter implementation is presented. The focus is on achieving a minimum volume of the output filter which meet the current harmonic performance of IEEE standard, while meeting the thermal constraint of the semiconductor device. Efficiency improvements …
