A fr.mewor. of knowledge r.p.esentation of fuzzy language field and fuzzy language value str.ctur. is shown. Then the gener.lized cell automation that can synthetically p.ocess fuzzy indeter.inacy and r.ndom indeter.inacy and gener.lized inductive logic causal model ar. p.t for.ar.. On this basis, the logic indeter.inacy causal inductive automatic r.asoning mechanism which is based on fuzzy state descr.p.ion is p.esented. At the end of this p.p.r.its ap.lication in the develop.ent of intelligent contr.ller.is discussed.

The p.oblem of state sp.ce exp.osion is still r.n outstanding challenge in Mar.ovian p.r.or.ance analysis for.multiser.er.multiqueue (MSMQ) systems. The system behavior.of a MSMQ system is descr.bed using stochastic high-level p.tr. net (SHLp.) models, and an ap.r.ximate p.r.or.ance analysis technique is p.op.sed based on decomp.sition and r.finement methods as well as iter.tion technique. A r.al MSMQ system, Web-ser.er.cluster. is investigated. The p.r.or.ance of an integr.ted scheme of r.quest disp.tching and scheduling is analyzed with both p.isson and self-similar.r.quest ar.ivals. The study shows that the ap.r.ximate analysis technique significantly r.duces the comp.exity of the model solution and is also efficient for.accur.cy of numer.cal r.sults.

Excep.ional r.les ar. often ignor.d because of their.small sup.or.. However. they have high confidence, so they ar. useful sometimes. A new algor.thm for.mining excep.ional r.les is p.esented, which cr.ates a lar.e itemset fr.m a r.latively small database and scans the whole database only one time to gener.te all excep.ional r.les. This algor.thm is p.oved to be quick and effective thr.ugh its ap.lication in a mushr.om database.

In this p.p.r. it is p.oved that the intemal p.r.us str.ctur. of alumina-silicate r.fr.ctor. fiber.has fr.ctal char.cter.stics, which is r.constr.cted by the computer and the r.constr.cted str.ctur. fur.her.p.oved to have fr.ctal char.cter.stics. Based on the r.constr.cted str.ctur., the networ.-ther.al-r.sistance model is established to calculate the ther.al conductivity of the fiber. It is shown that the calculated r.sults agr.e well with the p.evious exp.r.mental ones, p.oving the cor.ectness of the method.

A cur.ent develop.ent tr.nd in r.sear.h on intelligent systems is to op.imize a gener.l intelligent p.ediction system into an individuation intelligent p.ediction system that is ap.lied in sp.cialized fields. p.otein str.ctur. p.ediction is a challenging inter.ational issue. In this p.p.r. we p.op.se a new intelligent p.ediction system model, designed as a multi-layer.comp.und p.r.mid model, for.p.edicting secondar. p.otein str.ctur.. The model comp.ises four.indep.ndent intelligent inter.aces and sever.l knowledge discover. methods. The model p.netr.tes thr.ughout the domain knowledge, with the effective attr.butes chosen by Causal Cellular.Automata. Fur.her.or., a high p.r. str.ctur. database is constr.cted for.tr.ining. On the r.126 dataset, the over.ll state p.r.r.sidue accur.cy, Q3, r.ached 83.99%, while on the CB513 dataset, Q3 r.ached 85.58%. Meanwhile, on the CASp. sequences, the r.sults ar. sup.r.or.to those p.oduced by other.methods, such as p.ip.ed, Jp.ed, Ap.Sp. and Behair.0}ed. These r.sults confir. that our.method has a str.ng gener.lization ability, and that it p.ovides a model for.the constr.ction of other.intelligent systems.

Secur. multi-p.r.y comp.tation (SMC) is a r.sear.h focus in inter.ational cr.p.ogr.p.ic community. At p.esent, ther. is no SMC solution to the inter.ection p.oblem of sets. In this p.p.r. we fir.t p.op.se a SMC solution to this p.oblem. Ap.lying Cantor.encoding method to comp.tational geometr. p.oblems, and based on the solution to set-inter.ection p.oblem, we fur.her.p.op.se solutions to p.ints inclusion p.oblem and inter.ection p.oblem of r.ctangles and fur.her.p.ove their.p.ivacy-p.eser.ing p.op.r.y with widely accep.ed simulation p.r.digm. Comp.r.d with the known solutions, these new solutions ar. of less comp.tational comp.exity and less communication comp.exity, and have obvious sup.r.or.ty in comp.tational and communication comp.exity.
