. We restudy the phase diagram of the 2D-Ising model with competing interactions J1 on nearest neighbour and J2 on next-nearest neighbour bonds via Monte-Carlo simulations. We present the finite temperature phase diagram and introduce computational methods which allow us to calculate transition temperatures close to the criticalpoint at J2 = J1/2. Further on we investigate the character of the different...
This contribution describes a fully integrated field segment photo receiver for use in single lens reflex cameras. It supplies measurement values of five segments and the integral value via a standard interface to the camera processor. Individual calibration data of each sensor are stored in an on-chip EEPROM. The IC has been manufactured in a standard CMOS technology.
