  • Publication number: 20160288781
    Abstract: A motor speed control method and system for improving the performance of a running resistance evaluation of a hybrid electric vehicle are provided. The method includes determining whether a vehicle satisfies a running resistance evaluation start condition. When the vehicle satisfies the running resistance evaluation start condition, the speed of a motor is adjusted, which adjusts an input speed of a transmission to be equal to an output speed of the transmission. A speed adjustment of the motor is then completed using the speed of the motor and the output speed of the transmission.

  • Publication number: 20150230477
    Abstract: Disclosed herein is a composition containing a novel strain Streptomyces scopuliridis KR-001 strain or a culture broth thereof as an active ingredient for weed control. More particularly, the Streptomyces scopuliridis KR-001 strain of the present invention, culture broth thereof, or culture fraction shows an excellent weed-killing ability on grass weeds, broadleaf weeds, and hard-to-control weeds, and a medium composition containing a carbon source and a nitrogen source in an optimal condition may significantly increase yield of an active material produced by the strain with low cost. Therefore, the strain can be usefully employed to a herbicide composition for weed control and a method for weed control.
