The present invention provides an engine comprising a housing that defines a chamber. A portion of 50% or more in an area ratio of a reflecting surface of the reflector is formed as a scattering surface with a mean square inclination in a range of not less than 0. For each identified occurrence of the defined circuit structure, an injection data object is created corresponding to the plurality of components, and the injection data object is substituted into the portion of the circuit listing in place of the plurality of components. Repeat steps and until a first predetermined condition is true. To further reduce flicker and loss of brightness encountered when reducing the display time, anti-motion blur filtering of the input video signal is performed, where the display time and the amount and sort of filtering is jointly controlled based on the measured motion and characteristics of motion. Resource scheduling in the personal mobile grid is performed through an optimization model based upon the nectar acquisition process of honeybees.
