A method for coding video data includes scalably generating layers of wavelet coefficients based on a frame of video data, scalably generating motion vector data associated with the plurality of layers, and combining the motion vector data and the plurality of layers of wavelet coefficients into a coded video frame representing the frame of video data. The invention includes the use of heteropoly and isopoly acids and salts as the molybdenum-containing multi-functional catalysts for biomass conversion. The wafer sheet contains at least 23% sugar or an identical portion of a substance with the same technological properties as sugar, such as trehalose. For example, the dynamic road conditions are obtained from a detector that detects dynamic road conditions.
