Recent advances in theoretical methods combined with the advent of massively parallel supercomputers allow one to reliably simulate the properties of complex materials and device structures from first principles. We describe applications in two general areas: i) novel polymer composites for ultra-high-density capacitors, necessary for pulsed-power applications, such as electric rail guns, power conditioning,...
We propose an improved concept of pumping scheme for a synchronously-pumped optical parametric oscillator. The validity of the new concept has been verified with a femtosecond optical parametric oscillator making use of periodically-poled LiNbO/sub 3/.
A scheme for improving reliable operation of a PID governor of a hydraulic turbine generating unit is proposed. The parameters of governor and actuators are identified on-line to, a) detect their anomalous behaviours, b) facilitate the calibration of the proportional integral and derivative gain settings. An adaptive filter is used to detect the lightly damped oscillations of the system. The proposed...
