The Back propagation Neural Network (BPNN) has beenresearched and applied so broadly,to solve the problem that thetraining time of Back propagation network can be excessive, thestructure and training algorithm of priority ordered BP neuralnetworks are proposed. The neurons of its output layer havepriority ordered interconnections, during the training course, thetraining data tailed off gradually, so the algorithm may convergerapidly because of the decrease of the complexity ofperformance function. Compared with the conventional BPNN,the total iterative epochs of priority ordered BPNN are far lowerand the performance function can converge more rapidly in atext-independent speaker identification task.

Support Vector Machine(SVM) is a newgeneration learning system based on recent ad-vances in statistical learning theory. Thereare evidences showing that SVMs can deliverstate-of-the art performance in real-world ap-plication such as text categorisation, hand-written character reconition, image classifica-tion, biosequence analysis, etc. In this pa-per, we investigated the large scale regressionproblem by using SVMs, but instead of solvingquadratic programming slowly we try to accel-erate the regression speed by linear program-ming formulation using 1-norm or ∞-norm forthe model *** exper-iments show the linear programming gives usvery good performance without deterioratingthe results.

Digital watermarks have been proposed for thecopyright protections of multimedia products. Mostschemes were performed primarily for fidelityconsiderations, and not specifically to improve thedetector performance. In this paper, a robust and blindwatermarking scheme is presented. The concept ofcommunication with side information was applied at theencoder to improve the probability of detection withinacceptable fidelity, and the template matching techniquewas employed to estimate the undergone attacks inattacking channel. This scheme is optimized by theoptimal design of the encoder to match with the mediacontent and the decoder to adapt to the attack channelstate. Experiments show that our method is robust againstsome common attacks such as filtering, compression,rotation, scale, and translation. It can be applied to bothcolor and gray image.

CSTR is a sort of broad-using reactor inpolyreaction industry. The former experiment method canonly control the equipment on native computer using PID orbang-bang arithmetic. A new network-control method is putforward in this paper. The program uses Winsock module andinserts assembling language in the bottom layer to control theequipment on the server computer using CMAC. On eachclient computer in the LAN it can realize off-line simulation,on-line data sampling, control command sending and real-time graph monitoring. The method realizes remote intelligentcontrol in large-scale and enhances the equipment efficiencyand experiment effect.

Query localization is a recently proposed extension foron-demand routing protocols, which reduces overheads ofroute discovery. It has been found effective for DSR. How-ever,for distributed protocols like AODV,numerous issuesneed to be examined. This paper focuses on strategies forimplementing Query Localization in AODV by using cachesto maintain recent routing history in a distributed *** also present results of simulations that justify addingquery localization to AODV.

In this paper a new control scheme for uncertaintime-delay systems is put forward, in which the precise model ofthe plant is not necessary. The time delay term is taken outside thecharacteristic equation of the closed-loop transfer function. Anyvariation of time deley doesn't influence the system's dynamicperformance and the steady state. And the change of the process'parameters doesn't influence the stability of the system. Theparameters of the controller, adopted as PI controller,don't needadjust frequently so that it is easy to control the system in *** simulations show that the proposed scheme is superiorto the Smith predictor in the presence of large uncertainty inprocess dynamics.

With the rapid increase in the availableinformation over the Internet, it is important to developan efficient search and retrieval mechanism. In particular,the use of distributed search will be beneficial to manyusers. This paper presents two proposals to implementsuch approach. The first one is based on an intelligentpersonal agent to assist in finding pages relevant to thebehavior and characteristics of the user. Secondly,distributed knowledge base situated across the networkwill lighten the query-processing loads. Distributedknowledge bases on separate issues located at differentservers can be treated as integrated domain *** integrated knowledge is then used in an inferenceprocess at the main server. In this paper, the technicalissues on the above model will be addressed.

A novel multi-phase PWM DC-DCconverter is designed, in order to solve the problem ofmeeting the power supply requirments of the newgeneration microprocessor which requires 40-100Acurrents,lower voltage and bette current transientresponse. In multi-phase converter, how to balancethe currents in each phase is most important, andmaster-slave current sharing is an effective way. Themulti-phase converter,by distributing the power andload current results in smaller and lower cost transistorwith fewer input and output capacitors. It meets thespecifications of Intol's VRM9.0 design guideline forthe power supply of high-performance Pentium IVcentral processing units.
