For dynamic lightpath provisioning, a novel opticalsignaling protocol through optical communicationnetwork User Network Interface (UNI) is proposed. Itsupports multi-client addressing and meets the specialrequirements of optical networks. A CommnunicatingFinite State Machine (CFSM) model is utilized toformally specify and validate the protocol. Exceptionalhandling of the protocol is analyzed and fault-tolerantproperties are verified by Temporal Logic. Verificationsconfirm that file protocol performs actions to lightpathscorrectly under both normal and any time out conditions,with its no-deadlock, no-livelock, and other goodproperties.

This paper studied a general class of nonlinearstochastic systems, which can be approximated by T-Sfuzzy model. The problem both the control and the stateentering into the diffusion term is discussed here. A PDCstate feedback controller is proposed to guarantee themean-square stability of the closed-loop system. All theresults are represented by the linear matrix inequalities.

Openness is one of the features of modern opencontrollers. The porting ability of open control software is one ofthe most important aspects related to openness. In order torealize portability in future open control software, a deeperdiscussion about its conception is presented according to typicalhierarchical control software architecture. Then relativecomparison among three main corresponding standards ofprogramming language is presented because the realization ofportability mostly depends on developing tools. The discussionand comparing results may be helpful to improve or preserveportability of future open control software.

Traditional network management, with stress onmonitoring rather than control, can not meet the needs ofemerging multi-service networks with QoS guarantees. In thisarticle, we propose a policy-based solution to support deliveryand management of network infrastructure and enhancednetwork services. The article describes requirements formanagement of enhanced network services, hierarchical policyarchitecture, and provides an overview of policy-basedmanagement framework. Then we discuss policy-drivenservice management with emphasis on QoS management,dynamic service provisioning, and Internet pricing and billing.

A design method of H∞robust controllerbased on Smith predictor is presented. By analyzing theproperties of the Smith predictor, the robust performanceof a time-delay system is converted into a delay-free *** not only makes the analysis and synthesis easier butalso avoids of the rational approximation of time-delaythat can result in performance deterioration. Theoreticalanalysis and simulation shows that the design method notonly eliminates the time-delay but also improves therobust performance of the system signally. This workcontributes direct application of current robust controltoolbox to time-delay systems.

A wavelet based watermarking algorithm for digitalimage protection is proposed in this paper. Different from thetraditional watermarking algorithms, in this algorithm thewatermark is not embedded into the source image, but rather,used to derive a secret key. The secret key is generated bymixing-up the image features and the watermark kapt by therightful owner. Signification coefficients of the image afterdigital wavelet transformation are adopted for feature *** major merit of this algorithm is that the host image will notbe degraded for protection purpose and the algorithm is robustagainst various attacks, such as image compressing, blurring andcropping. Experimental results show the effectiveness androbustness of this algorithm.

This paper proposes a new kind of visual method forman-on-board order-picking in automatedstorage/retrieval system (AS/RS) using networktechnology and panel pc. By using the storageassigmnent policies and sequencing algorithms, we canimprove the performance of the man-on-boardorder-picking method, increasing the throughputcapacity of AS/RS. After introducing the framework ofthis new method, we present an analytical model andanalyze the system performance for the case of usingdynamic job inserting.
