Abstract: A BLDC motor server includes a stator configured in a hollow cylindrical shape and comprising a plurality of teeth around which a plurality of coils is wound to form an electromagnetic field, respectively; and a rotor configured in a cylindrical shape rotatable within the stator and comprising a plurality of permanent magnets, each having an arched section in which an outer circumference side is extended in both directions from a rotation center side, wherein the plurality of permanent magnets is disposed, so that facing outer surface portions of two permanent magnets neighboring each other are adjacent to each other, and wherein a width Wo of the outer circumference side of each permanent magnet is configured to be smaller than a width Wc of the rotation center side thereof. The BLDC motor may reduce a noise and a vibration as well as increasing an efficiency of the motor.

Abstract: A method and apparatus for training a neural network model are provided. The method of training a neural network model includes storing replay samples selected from among online stream samples in a replay buffer, selecting batch samples from the replay samples based on selection frequencies of the respective replay samples, determining a freeze layer group of the neural network model based on forward propagation of the neural network model using the batch samples, and training the neural network model based on backward propagation of layers not in the freeze layer group.

Abstract: Provided are a processing device, an electronic device, and a method of outputting a video. The processing device includes a pull-down cadence detector configured to receive an input video stream generated by pulling down raw data from an external device, detect a pull-down cadence format indicating a rate at which the raw data is pulled down based on the input video stream, and output detection result information; and a pull-down cadence controller configured to output an output video stream having a second frame rate that is an integer multiple of a first frame rate of the raw data, based on the input video stream and the detection result information.
