Abstract: An apparatus for predicting performance of a wheel in a vehicle: includes a learning device that generates a latent space for a plurality of two-dimensional (2D) wheel images based on a convolutional autoencoder (CAE), extracts a predetermined number of the plurality of 2D wheel images from the latent space, and learns a dataset having the plurality of 2D wheel images and performance values corresponding to the plurality of 2D wheel images; and a controller that predicts performance for the plurality of 2D wheel images based on a performance prediction model obtained by the learning device.

Abstract: Disclosed herein are a decoding method and apparatus and an encoding method and apparatus that perform inter-prediction using a motion vector predictor. For a candidate block in a col picture, a scaled motion vector is generated based on a motion vector of the candidate block. When the scaled motion vector indicates a target block, a motion vector predictor of the target block is generated based on the motion vector of the candidate block. The motion vector predictor is used to derive the motion vector of the target block in a specific inter-prediction mode such as a merge mode and an AMVP mode.

Abstract: An image encoding/decoding method is provided. An image decoding method of the present invention may comprise deriving an intra-prediction mode of a current luma block, deriving an intra-prediction mode of a current chroma block based on the intra-prediction mode of the current luma block, generating a prediction block of the current chroma block based on the intra-prediction mode of the current chroma block, and the deriving of an intra-prediction mode of a current chroma block may comprise determining whether or not CCLM (Cross-Component Linear Mode) can be performed for the current chroma block.

Abstract: The present invention relates to a phosphine precursor for the preparation of a quantum dot, and a quantum dot prepared therefrom. Using the phosphine precursor for the preparation of a quantum dot of the present invention, a quantum dot with improved luminous efficiency and higher luminous color purity can be provided.

Abstract: Disclosed is a ball throwing game machine in which, when a ball is hit by a hitting device whose hitting force is controlled by a handle, the ball is thrown to fly toward a game operation part and enters the game operation part, and here, a control device, which has received a light emission color signal and a ball entry signal from the game operation part, outputs a score signal to a score display device that corresponds to the light emission color signal from the game operation part to display a predetermined score on the score display device corresponding to the light emission color signal from the game operation part at the time the ball enters.

Abstract: The present invention relates to a game method using a ticket output game machine in which, at a moment that a ball throwing portion horizontally moving along a rail portion arrives at a determined position on a game plate, a drop button is manipulated to allow a ball gripped by the ball throwing portion to be dropped onto the game plate so as to insert the ball into a bonus hole device or ball insertion holes corresponding to LEDs emitting light having different colors. An LED color signal of the ball insertion hole into which the ball is inserted or a signal of the bonus hole device or a ball discharge hole is analyzed and a score corresponding thereto is output to a general score plate or a bonus score plate. A number of tickets corresponding to the score is output through a ticket output portion and obtained.

Abstract: Disclosed is a ticket outputting game machine. The ticket outputting game machine includes a body having guide rails formed on a top surface thereof, a hitting portion formed on a front end of the guide rails, and a handle controlling a hitting force of the hitting portion on a front surface thereof, ticket display devices installed in a zigzag structure on both sides of the guide rails, and a ball position determination portion determining a held position of a ball between the guide rails to hit the ball by the hitting portion such that the ball moves along the guide rails and is held at a position determined by the ball position determination portion and the number of tickets displayed on the ticket display device corresponding to the position of holding the ball are output.
