Most researches of time series forecasting mainly focus on the aspect of pursuing the numerical forecasting precision by constructing the quantitative model. But in the real world, precision is sometimes not necessary for perceiving and reasoning of human, and the qualitative forecasting of time series is able to satisfy requirement of some decision problems. In this paper, a new qualitative forecasting...
A compact and all-solid-state high-voltage pulse generator based on magnetic pulse compression system (MPCS) and transmission line transformer (TLT) is presented. A closed magnetic core transformer switched with thyristors is employed as a fast step up source for MPCS. Three high voltage 50 Ω coaxial cables are connected as a three-stage TLT with the input impedance of 17 Ω and the output impedance...
