The ultrafast pump–probe measurement represents a key technique to study fs–ps dynamics. asynchronous optical sampling (ASOPS) method realizes fast and long time-range with high time resolution using different repetition frequency light pulses. difference Δ f is an important parameter, as it dictates the resolution. However, usual ASOPS measurements require complex precise stabilizer control or...

The main advantages of variable sampling plans are the existence small sample size for effective decision and receiving good information on quality characteristics. But samples some time may lead to wrong during inspection lot can increase risk producer or consumer. same scenario happen in double triple also due sizes. control professionals suggest multiple when is very large. Hence an attempt ...
