  • Publication number: 20250030893
    Abstract: Provided is an apparatus and method for encoding/decoding a moving picture based on adaptive scanning. The moving picture apparatus and method can increase a compression rate based on adaptive scanning by performing intra prediction onto blocks of a predetermined size, and scanning coefficients acquired from Discrete Cosine Transform (DCT) of a residue signal and quantization differently according to the intra prediction mode. The moving picture encoding apparatus includes: a mode selector for selecting and outputting a prediction mode; a predictor for predicting pixel values of pixels to be encoded of an input video based on the prediction mode to thereby output a residue signal block; a transform/quantization unit for performing DCT onto the residue signal block and quantizing the transformed residue signal block; and an encoder for adaptively scanning and encoding the quantized residue signal block based on the prediction mode.

  • Patent number: 11075395
    Abstract: Disclosed is a fuel cell membrane electrode assembly (MEA) embodiment including an anode layer; at least one exchange membrane that is disposed on the anode layer as either a single-layered structure including one exchange membrane or a multi-layered structure including a plurality of exchange membranes, each exchange membrane of the at least one exchange membrane consisting of a film comprising hexagonal boron, and the at least one exchange membrane having a total thickness ranging from 0.3 to 3 nm; an interfacial binding layer that completely covers an exposed surface of one exchange membrane which is obverse to the anode layer and that consists of poly(methylmethacrylate) (PMMA) as a binder material; and a cathode layer formed on the interfacial binding layer. Alternately, a fuel cell membrane electrode embodiment may completely eliminate the interfacial binding layer and both embodiments provide superior fuel cell performance.
