The embodiments of the present invention provide for methods, devices, and systems adapted to reduce flickers introduced in the encoding process, particularly during the generation of intra-coded pictures. A deflection angle command signal generation means generates a deflection angle command signal for estimating an aerodynamic coefficient indicating the aerodynamic characteristics of an airframe. This arrangement allows air to flow smoothly between the electric motor and the battery unit. The computer physically weaves braids in the 2D+1 space-time of the lattice, and uses this braiding to carry out calculations.
