Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by ...
Abstract: This letter proposes a discrete-time integral sliding mode (DT-ISM) control strategy for linear time-invariant systems subject to matched and unmatched disturbances. The DT-ISM strategy is ...
Abstract: Real time convolution of radio frequency signals has been demonstrated using organic semiconductor based surface acoustic wave convolver employed with signal-generator and oscilloscope. The ...
