Electric vehicle (EV) driving range directly reflects EVs' performance, safety, reliability and economy. EV has gained wide attention in recent years. However, most of researches are carried out under ideal conditions and the existing methods have numerous drawbacks. This paper presents a novel prediction method based on a least squares support vector machine (LSSVM) model with parameters γ and σ2...
The new generation ESA SEU Monitor was used in Beijing HI-13 Tandem accelerator after initial cross-calibration with the proton beams at Paul Scherrer Institu. Heavy ion cross sections obtained at HI-13 were very consistent with those from HIF and RADEF facilities. Beam homogeneity was also verified based on the SEU physical bitmap. In addition, the cross section dependence on ion energy near direct...
Heavy ion irradiation facility dedicated for single event effect ground simulation testing has been developed on Beijing HI-13 tandem accelerator. Two dimensional magnetic scanning method was used to produce a large and uniformly distributed beam. Non uniformity of beam distribution is less than 10% over an area of 100mm×100mm. In order to enhance the output energy of tandem accelerator highly stripped...
How to extract effective discriminant features of high-resolution range profile (HRRP) is one of the issues for radar automatic target recognition (RATR). In this paper, a novel method for extracting discriminant features is proposed by using kernel optimal transformation and cluster centers techniques (KOT-CC). In addition, to alleviate the effect of independent noises on the discrimination, we propose...
