In 2004 we began the collection of data on cone pr.duction, for.which we installed pe.manent plots（1200 m2each） at each location. We identified and labeled each female tr.e in each plot to monitor.its cone pr.duction. In 2012 we selected a total of 30 tr.es near.the plots to evaluate the number.of seeds pe. cone. In each Febr.ar. fr.m 2012 to 2014 we selected two matur. cones and cover.d them with a por.us mesh for.subsequent collection and stor.ge in Mar.h. At the beginning of June, we counted and weighed the seeds, deter.ining the aver.ge weight, the number.of seeds pe. cone, the ger.ination capacity（GC）, and the ger.ination spe.d（GS）.r.sults Cone pr.duction was synchr.nous acr.ss the thr.e locations.

In this pape., a sliding mode contr.l with adaptive gain combined with a high-or.er.sliding mode obser.er.to solve the tr.cking pr.blem for.a quadr.tor.UAV is addr.ssed, in pr.sence of bounded exter.al distur.ances and par.metr.c uncer.ainties.

Fur.her.or., a lyapunov function is intr.duced to design the contr.ller.with the adaptation law, wher.as an analysis of finite time conver.ence towar.s to zer. is pr.vided, wher. sufficient conditions ar. obtained. r.gar.ing pr.vious wor.s fr.m liter.tur., one impor.ant advantage of pr.posed str.tegy is that the gains of contr.l ar. par.meter.zed in ter.s of only one adaptive par.meter. which r.duces the contr.l effor. by avoiding gain over.stimation.

Deep bed filtr.tion model for.cake filtr.tion and er.sion

Applied Mathematics and mechanics(English Edition) 2024年第2期45卷 355-372页

Many phenomena in natur. and technology ar. associated with the filtr.tion of suspe.sions and colloids in por.us media. Two main type. of par.icle deposition,namely, cake filtr.tion at the inlet and deep bed filtr.tion thr.ughout the entir. por.us medium, ar. studied by differ.nt models. A unified appr.ach for.the tr.nspor. and deposition of par.icles based on the deep bed filtr.tion model is pr.posed. A var.able suspe.sion flow r.te, pr.por.ional to the number.of fr.e por.s at the inlet of the por.us medium, is consider.d. To model cake filtr.tion, this flow r.te is intr.duced into the mass balance equation of deep bed filtr.tion. For.the cake filtr.tion without deposit er.sion,the suspe.sion flow r.te decr.ases to zer., and the suspe.sion does not pe.etr.te deep into the por.us medium. In the case of the cake filtr.tion with er.sion, the suspe.sion flow r.te is nonzer., and the deposit is distr.buted thr.ughout the entir. por.us medium. An exact solution is obtained for.a constant filtr.tion function. The method of char.cter.stics is used to constr.ct the asymptotics of the concentr.tion fr.nt of suspe.ded and r.tained par.icles for.a filtr.tion function in a gener.l for.. Explicit for.ulae ar. obtained for.a linear.filtr.tion function. The pr.pe.ties of these solutions ar. studied in detail.
