1098-4402= Three 6-cell 805 MHz superconducting cavity prototypes for acceleration in the velocity range of about 0.4 to 0.53 times the speed of light have been fabricated and tested. The quality factors (Q0) were between 7 109 and 1:4 1010 at the design field (accelerating gradient of 8–10 MV=m). The maximum gradients reached were between 11 and 16 MV=m; in each case, the Q0 values were 3 109 ...
This paper presents a mapping scheme for p a d e l pipelined execution of the Backpropagation Learning Algorithm o n dtktributed memory multiprocessors (DMMs). The proposed implementation ezhibits training set parallelism that involves batch updating. Simple algorithms have been presented, which allow the data transfer involved in both forward and backward execution3 phases of the backpropagati...

A room-temperature pulsed operation was demonstrated using lateral current injection-type lasers composed of a 400-nm-thick GaInAsP core layer with compressively strained 5 quantum wells. A threshold current of 105 mA and corresponding density of 1.3 kA/cm(2) (260 A/cm(2) per well) were obtained with the stripe width of 5.4 microm and the cavity length of 1.47 mm. A fundamental transverse mode ...
