In this paper, we provide new preconditioner for saddle point linear systems with (1,1) blocks that have a high nullity. The preconditioner is block triangular
CMOS devices play a major role in most of the digital design, since CMOS devices have larger density and consume less power. The integrated circuit performance
A low-voltage, high-speed flash ADC is designed. The bottleneck of the operation speed in the low-voltage region is the delay time increase of the comparator. T
The lag-luminosity relation for gamma-ray bursts (GRBs) is an anti-correlation between the time lag, ?lag, which represents the delay between the arrival of har
