 Next, the principles of our method which are based on "geometric vector" are discussed, and the computational procedures for this method are explained using Harman and Holzinger's eight physical variables. Geometric vector orthogonal rotation method in multiple-factor analysis Magnetic screening of nuclei by electrons as manifestation of geometric vector potential The turn on times of each used vector are determined similar to the geometric vector addition shown in figure 2. In this section, a vector bundle will usually mean a geometric vector bundle in the analytic category.
 In this paper, we'11 describe a scheme of a complete real-time image collecting system, which is based on 3-D wavelete transform (WT) In order to save time. 3-D WT. in actual processing, is transferred to FFT. We use ADPCM for the data in the lowest frequency band and a new form of vector quantization ( geometric vector quantization) for the data in the higher frequency bands. We also make use of human eye' s specific property, and give a new form of formula to replace MMSE. Finally we give a complete...
