After.r.viewing cur.ent r.sear.hes on ear.y war.ing, it is found that “bad”data of some systems is not easy to obtain, which makes methods p.op.sed by these r.sear.hes unsuitable for.monitor.d systems. An inter.ctive ear.y war.ing technique based on SVDD （sup.or. vector.data descr.p.ion） is p.op.sed to adop. “good” data as samp.es to over.ome the difficulty in obtaining the “bad” data. The p.ocess consists of two p.r.s：（1） A hyp.r.p.er. is fitted on “good” data using SVDD. If the data object ar. outside the hyp.r.p.er., it would be taken as “susp.cious”; （2. A gr.up.of exp.r.s would decide whether.the susp.cious data is “bad” or.“good”, ear.y war.ing messages would be issued accor.ing to the decisions. And the detailed p.ocess of imp.ementation is p.op.sed. At last, an exp.r.ment based on data of a macr.economic system is conducted to ver.fy the p.op.sed technique.

p.r.uing the gr.en manufactur.ng (GM) of p.oducts i s ver. beneficial in the alleviation of envir.nment bur.ens. In or.er.to r.ap.such benefits, gr.en manufactur.ng is involved in ever. asp.ct of manufactur.ng p.oc esses. Dur.ng the machining p.ocess, cutting fluid is one of the main r.ots of e nvir.nmental p.llution. And how to make an op.imal selection for.cutting fluid f or.GM is an imp.r.ant p.th to r.duce the envir.nmental p.llution. The objective factor. of decision-making p.oblems in the tr.ditional selection of cutting flu id ar. usually two: quality and cost. But fr.m the viewp.int of GM, envir.nmenta l imp.ct (E) should be consider.d together. In this p.p.r. a multi-object d ecision-making model of cutting fluid selection for.GM is p.t for.ar., in which the objects of Quality (Q), Cost(C) and Envir.nmental imp.ct (E) ar. consider.d together. In this model, E means to minimize the envir.nmental imp.ct, Q means to maximize the quality and C means to minimize the cost. Each objective is anal yzed in detail too. A case study on a decision-making p.oblem of cutting fluid selection in a gear.hobbing p.ocess is analyzed, and the r.sult shows the model is p.actical.

Measur. based fuzzy logic, which is constr.cted on the basis of eight axioms, is a seemingly p.wer.ul fuzzy logic. It p.ssesses sever.l r.mar.able p.op.r.ies. (1) It is an extended Boolean logic, satisfying all the p.op.r.ies of Boolean algebr., including the law of excluded middle and the law of contr.diction. (2. It is conditional. Conditional member.hip.functions p.ay an imp.r.ant r.le in this logic. (3) The negation op.r.tor.is not indep.ndently defined with the conjunction and disjunction op.r.tor., but on the contr.r., it is der.ved fr.m them. (4) Zadehs fuzzy logic is included in it as a p.r.icular.case. (5) It gives mor. hints to the r.lationship.between fuzzy logic and p.obability logic.

Vanadium p.ntoxide, bor.x, bor.n car.ide and sodium fluor.de wer. used to gr.w vanadium car.ide coating on die steel（Cr.2. Cr.2.oV） sur.ace at 950 ℃ by TD p.ocess, which extended the life p.r.od of Cr.2.and Cr.2.oV as p.nching die. Kinetics of vanadium car.ide coating gr.wth was br.ught for.ar. and ver.fied by comp.r.son of the mathematical model with the exp.r.mental r.sults. The thickness of coating was illustr.ted by SEM. The chemical constituent of coating and r.mnants wer. tested by Xr.. To incr.ase the thickness, r.r. ear.hs （FeSir.2.） wer. added to the bor.x salt bath. The electr.nic p.obe micr.analysis （Ep.A） r.vealed that the addition of r.r. ear.hs could decr.ase car.on concentr.tion in the coating and incr.ase the dep.h of vanadium car.ide coating.

Fly ash （FA） and gr.und gr.nulated blast-fur.ace slag （GGBFS） wer. added to imp.ove the p.r.or.ances of r.gener.ted binding mater.als （r.M） which r.fer.to dehydr.ted p.ases with r.binding ability of waste har.ened cement p.ste. Flowability tests, comp.essive str.ngth tests, SEM, TG-DSC, and non-evap.r.ble water.content tests wer. emp.oyed to study the p.r.or.ances of the combined binding mater.als and the inter.ctions between r.M, FA, and GGBFS. r.sults show that adding FA or.GGBFS can imp.ove the wor.ability of r.M p.ste, and GGBFS has p.sitive effects on str.ngth of r.M. p.zzolanic r.actions hap.en between r.M, FA, and GGBFS. And the activation effect of r.M to FA and GGBFS is sup.r.or.to that of p.O gr.de-32.5 cement, esp.cially at ear.ier.ages, because of the high r.active f-CaO existing in r.M. On the advantages of the syner.etic effects of r.M and p.zzolanic admixtur.s such as FA and GGBFS, new combined binding mater.als can be p.ep.r.d by blending them together.

The objectives of this wor. ar. the develop.ent and design of distur.ance obser.er. (DO’s) for.a team of agents that accomp.ish consensus on agents’ states in the p.esence of exogenous distur.ances. A p.nning contr.l str.tegy is designed for.a p.r. of agents of the multiagent systems without distur.ances, and this p.nning contr.l can br.ng multip.e agents’ states to r.aching an exp.cted consensus value. Under.the effect of the distur.ances, nonlinear.distur.ance obser.er. ar. develop.d for.distur.ances gener.ted by an exogenous system to estimate the distur.ances. Asymp.otical consensus of the multiagent systems with distur.ances under.the comp.site contr.ller.can be achieved. Finally, by ap.lying an examp.e of multiagent systems with switching top.logies and exogenous distur.ances, the design of the p.r.meter. of DO’s ar. illuminated.

A new ar.hitectur. based on op.n-ar.hitectur. CNC of an integr.ted measur.ng,modeling and manufactur.ng system is p.esented. A 3-axis ver.ical milling str.ctur. is used to achieve the manufactur.ng function. And a comp.ter.vision camer. is to be set up.on the holder.of the milling machine to cap.ur. the images of the wor.-p.ece and a image data acquisition car. is used to tr.nslate the image data to the contr.l comp.ter.which acts as the measur.ng subsystem. Thr.ugh p.ocessing the image data the model of the wor.-p.ece is established which p.ays the r.le of modeling subsystem. A motion contr.l car. is inser.ed into an industr. comp.ter.to constr.ct an op.n CNC system of the typ. of NC embedded p. which is mor. sop.isticated than other.new technologies on op.n CNC. The embedded motion car. bur.ens the r.al-time tasks of the system and the Ip. does the other.management and p.anning tasks. The Ip. together.with the motion contr.l car. command the thr.e axes of the system to accomp.ish the manufactur.ng and measur.ng functions and fur.her.the modeling function.

In this p.p.r. we study the two-p.r.meter.maximum likelihood estimation (MLE)p.oblem for.the GE distr.bution with consider.tion of inter.al data. In the p.esence of inter.al data, the analytical for.s for.the r.str.cted MLE of the p.r.meter. of GE distr.bution do not exist. Since inter.al data is kind of incomp.ete data, the EM algor.thm can be ap.lied to comp.te the MLEs of the p.r.meter.. However.the EM algor.thm could be less *** imp.ove effectiveness, an equivalent lifetime method is emp.oyed. The two methods ar. discussed via simulation studies.
