Abstract:
Disclosed are an apparatus and a method for controlling an output of a distributed power. The method for controlling the output of the distributed power connected to a system according to an embodiment of the present invention comprises the steps of: measuring frequency and output at an operating point based on the operating point of a generator; calculating a first droop coefficient between the operating point and the maximum amount of power generation and a second droop coefficient between the operating point and the minimum amount of power generation by using the measured frequency and output; calculating the percentage loading of a load of the generators consisting of the distributed power according to the first droop coefficient and the second droop coefficient; and controlling the output of the generators according to the calculated percentage loading of the load.

Abstract:
A composition for delivering nucleic acids using a cationic polymer conjugate is provided to improve significantly the efficiency of delivering an oligo-nucleic acid such as siRNA and antisense nucleic acid in a cell and decrease the cytotoxicity caused by a carrier itself, thereby being usefully used in a field of targeting the delivery of the oligo-nucleic acid. A composition for delivering nucleic acids consists of 5-200 sequences of an animal cell including a cationic polymer conjugate formed by polymerizing hyaluronic acid and polyethylenimine using a crosslinking agent such as N-(2-dimethylaminopropyl)-N'-ethylcarbodiimide(EDC), 1-cyclohexyl-3-(2-morpholinoethyl) carbodiimide(CMC), dicyclohexyl carbodiimide(DCC), diisopropylcarbodiimide(DIC), N-ethyl-3-phenylisoxazolium-3'-sulfonate(Woodward's reagent K), and N,N'-carbonyldiimidazole(CDI). A composition for delivering nucleic acids in an animal cell includes a complex generated by an electrostatic bond between the cationic polymer conjugate with a nucleic acid.
Abstract:
PURPOSE: A method and apparatus for valancing loads and for allocating power based on the load prediction of neighbor cells are provided to minimize load terminals by determining a power and handover terminal group. CONSTITUTION: A reception unit(300) receives information for predicting each load of neighbor base stations from the neighbor base stations. A first determination unit(306) determines a power and handover terminal group based on information for predicting each load of the neighbor base station. A control unit(302) determines the power and handover terminal group for minimizing load terminals using information for predicting the load of the neighbor base station. The load terminal includes a minimum demand transmission rate which is bigger than an average reception rate.
