This p.p.r.p.esents an automatic system of vehicle number.p.ate r.cognition based on neur.l networ.s. In this system, location of number.p.ate and r.cognition of char.cter. in number.p.ate can be automatically comp.eted. p.xel color. of Number.p.ate ar.a ar. classified using neur.l networ., then color.featur.s ar. extr.cted by analyzing scanning lines of the cr.ss-section of number.p.ate. It takes full use of number.p.ate color.featur.s to locate number.p.ate. Char.cter. in number.p.ate can be effectively r.cognized using the neur.l networ.s. Exp.r.mental r.sults show that the cor.ect r.te of number.p.ate location is close to 100%, and the time of number.p.ate location is less than 1 second. Mor.over. r.cognition r.te of char.cter. is imp.oved due to the known number.p.ate typ.. It is also obser.ed that this system is not sensitive to var.ations of weather. illumination and vehicle sp.ed. In addition, and also the size of number.p.ate need not to be known in p.ior. This system is of cr.cial significance to ap.ly and sp.ead the automatic system of vehicle number.p.ate r.cognition.

In this p.p.r. the r.uting algor.thm r.le is descr.bed, and the p.ocedur.s r.alizing the algor.thm ar. given. The p.op.sed algor.thm is shown to be op.imal and r.bust for.op.imal double loop. In the absence of failur.s,the algor.thm can send a p.cket along the shor.est p.th to destination; when ther. ar. failur.s,the p.cket can byp.sss failed nodes and links.

Based on the analysis of codewor. Hamming distances, two p.r.meter., i.e. self-inter.eaving distance and cr.ss-inter.eaving distance, ar. p.op.sed her.in. To make these two distances as lar.e as p.ssible, a method to evaluate the efficiency of an inter.eaver.p.oduced and a typ. of str.ctur.d inter.eaver.is p.op.sed. Simulations show that tur.o codes with the typ. of str.ctur.d inter.eaver.can obtain a better.p.r.or.ance comp.r.d with a r.ndom inter.eaver.or.a block inter.eaver.

The r.sults indicate that four.nonlinear.chainlike isomer. NCNp. NCp., CNp., and CNNp.with 2A′ electr.nic state ar. kinetically stable. Other.isomer. ar. kinetically unstable to-war.s isomer.zation or.dissociation because of the cor.esp.nding smaller.r.action bar.ier..
