Drawing from his observations, the border patterns of Santhal Pargana were examined and two symmetrical border patterns (5) and horizontal Glide reflection (6) (TG) and Translation, Horizontal
line reflection and horizontal Glide reflection (THG)] were observed.
From the first layer
line reflection on the patterns, the fiber period, that is the length of the unit-cell c-axis, could be estimated [16].
Suitable for motors from 1.5 to 30 Kw with frequencies up to 400l-lz (4 to 24A) or to 200Hz (33 to 66A), this proven technology reduces high output voltage dv/dt from IGBT motor drives and restricts over-voltages caused by
line reflections on motor cables.
