Electric utilities and regulators face difficult challenges evaluating new energy efficiency and smart grid programs prompted, in large part, by recent state and federal mandates and financial incentives. It is increasingly difficult to separate electricity use impacts of individual utility programs from the impacts of increasingly stringent appliance and building efficiency standards, increasi...

This dissertation is a systematic study of electric power distribution system reliability evaluation and improvement. Reliability evaluation of electric power systems has traditionally been an integral part of planning and operation. Changes in the electric utility coupled with aging electric apparatus create a need for more realistic techniques for power system reliability modeling. This work ...

The future More Electric Aircraft (MEA) technology focus on increasing the use of electrical equipment to a larger extent, e.g. replacing conventional hydraulic and pneumatic actuators with electromechanical or electro hydrostatic actuators to reduce weight, cost and maintenance. Advances in enabling technologies of electric power generation, distribution, and utility equipment have made the us...

In the generation of photoemitted electron bunches for the use in accelerators, metals are limited by their low QE. Previous work [P. Musumeci et al., Phys. Rev. Lett. 110(2013)] has shown that charge yield from infrared light is increased by a factor of 120 by etching nanopatterns into the cathode. However, utility of the electron bunch is also based on its thermal emittance, or angular spread...

Have you ever wondered what it would be like to have a self-sustained charging system that does not cost you any money on your electric bill? Electric car owners know that even though their cars do not require gasoline to run, they will require electricity and like everyone else that is tied to the grid will have to pay a price per kilowatt hour that is determined by their utility company. With...

background & purpose: in the health sector, in addition to the important consequence of treatment, health system should meet the expectations regarding the desirability of services. expectations and perceptions of patients about the desirability of services play an important role in selecting hospitals, their loyalty to the organization & replanning to purchase. thus the present study has been ...
