A graphical user interface supports an interactive client-server authentication based on Random Partial Pattern Recognition algorithm. The first filter branch includes a first resistance in series with an input and a first output, and N parallel paths across the first output. Said catalysts may be dispersed in immiscible aprotic solvents to enhance transportation and safety considerations prior to use. The mold unit includes a sprue bushing for communicating with the nozzle. Slope portions are formed after forming uniformly and thinly wall thickness of both upper and lower flat portions or either of the upper or the lower flat portion to 90% or less of that of the metal plate to be formed to obtain trapezoidal irregularities by forming flat portions which contact upper and lower cells and slope portions which interconnect the upper and the lower flat portions.
