A robust method for whole course fault detection anddiagnosis in control systems is proposed. The diagnosisscheme is based on the fuzzy dynamical model that is anaggregation of a set of local linear models representing thelocal dynamic behavior of the whole system. Then aresponding observer-based fault diagnosis scheme isdeveloped to detect and isolate sensors' faults. In order toquantitatively evaluate the robustness of the generatedresidual, we present a performance index based on theanalysis of residual. Genetic algorithm is then used tooptimize the performance index and find the optimalmatrices for the generation of robust residual. Thediagnosis strategy is verified through simulation studieson temperature sensors fault diagnosis in the superheatedsteam control system of a power plant.

When multimedia traffic is introduced into codedivision multiple access (CDMA) mobile networks,power should be assigned to users according todifferent bit rate and quality of service (QoS)requirements, so as to provide each user an acceptableconnection. In this work, linear power assignment andits impact on the capacity of multimedia widebandCDMA systems are studied. It is indicated that whenone cell of multimedia CDMA system is considered,and if user's requirement of QoS is given by averagesignal-to-interference ratio (SIR), power assignment isequivalent to finding the solution of a set of linearinequations. After the condition of the solutionexistence is derived and the solution is obtained, a newpower assignment scheme is proposed. The numericalresults show that the new scheme could enhane thesystem capacity and could have a more efficient utilityof system resoure than the conventional scheme.

In information integration systems based onmediator/wrapper archtecture, returning all theintegrated results to the mediator client at once couldincur great disaster on the mediator client. If the query isn't specified precisely by user, the serverwould generate too many irrelevant results. And users ofWeb have a tendency not to access all the results thoughthe results are relevant to them. Moreover, when the mediator clients are deployed onmobile devices with limited hardware capacity andnetwork resources, the situation becomes worse. In this paper, we propose a new mechanism fortransferring integrated results partially to mediatorclients by adopting cursor notion of relational DBMS.

The acoustic models based on the convenional Hidden MarkovModel have not high recognition performance for the connectedMandarin digit string, because highly confusable syllables *** state-specific linear discriminant analysis is adopted toreduce the substitution errors of confusable digits. Therecognition rate for the isolated digit is increased from 97.16%to 99.32%;and the unknown length digit string from 86.5% to88.18%. Furthermore experiments showing that most of thetypical confusions can be discriminated by the pitch contourpatterns the tone discrimination models are trained and the two-pass recognition algorithm to combine the acoustic modellikelihood and the tone discrimination model likelihood isdeveloped. By tone discrimination the relative digit string errorrate is reduced by 37.4%. The unknown length digit stringrecognition rate and its digit recognition rate are increased from88.18% and 97.54% to 92.6% and 98.21%. respectively.

The robustness of optical networks with respect to theaccumulation of homodyne crosstalks was statisticallystudied in this paper, with emphases on the effect ofnetwork topology, identified by the network scale andphysical connectivity. The homodyne crosstalks, a majorand irreparable signal quality degrading factor, are inducedby non-ideal optical switches and demux/mux pairs atoptical cross-connect (OXC) in optical wavelengthdivision multiplexing (WDM) networks. For the first time,our numerical simulations revealed that in a given networkscale, there exists an optimum physical connectivity, atwhich the resultant overall accumulation of homodynecrosstalks can be minimized. We also took into account thepractical network scale and the limit of crosstalk ratio ofthe state-of-the-art optical switches and demultiplexers. Itwas shown that proper network design could greatly relaxthe requirements posed on the optical switches anddemultiplexers.

This paper investigates effect of dithering in improvingthe visual quality of an image subband coder. A subband coderwith scalar quantization of lowest frequency subband andpyramid vector quantization of high frequency subbands wassimulated For subband quantizer both types of subtractive andnon-subtractive dither were examined, and the coder performancewas compared with the non-modified coder by subjective andobjective tests. In a series of pair comparison subjective tests,coder with subtractive dither gained a total average score of 0.32(in the scaled range of [-1,1]), and the coder with non-subtractivedither gained an average score of 0.24 compared to non-ditheredcoder. As an objective measure the correlation betweenreconstructure error and original image was calculated, whichshows that dithering will result an average of 10 percentreduction in case of non-subtractive dither and 12 percentreduction for subtractive dither.

In CDMA systems, the number of users thateach cell can support is limited by the total interferencereceived at each base station and will vary with time. Whena system is congested, admitting a new call can only makethe link quality worse for ongoing calls and may result incall dropping. Thus the system needs a CAC (CallAdmission Control) policy for new calls and handoff calls tomaintain acceptable connections for existing users. So inthis paper,we propose a kind of intelligent CAC policy,which can adjust the CAC algorithm and its thresholdaccording to the current traffic load in local and neighboringcells, and handoff user density etc by fuzzy inference,system-level simulation and self-learning, and increase thewhole system performance. At last, we compare the methodwith stationery and uniform CAC policy, and analyze thepossibility of this policy applying to the multi-servicesystems.

Resource ReSerVation Protocol (RSVP) can pro-vide quality of service guarantees for real-time services. How-ever, RSVP suffers from the mobility problem in wireless mo-bile networks. To reduce the service disruptions during handoffs,the fast handoff mechanism which makes preparations for pro-spective handoffs was generally used. In this paper, we illustratean infrastructure with efficient intra-domain mobility manage-ment in IP-based wireless networks. We propose mobile RSVPand fast handoff mechanisms using the techniques of aggregatereservation and path extension. Performance evaluations areperformed through simulations.

-Because of the oscillation of window on TCPwindow control mechanism, Internet applications cannotget rate and burstiness guaranteed through TCP even ifthe network layer provides guaranteed service or explicitnetwork available service rates. Therefore,in this paperwe present a new technique, called TCP Leaky Bucket(TCPLB), to realize not only rate but also burstinessguarantees for the TCP Internet applications. Instead ofadding an independent leaky bucket shaper on the outputof TCP, the proposed method adapts the window size inTCP widow to regulate the sending pattern of TCP output,Further, due to filter bank summation property undermin-plus algebra, the TCPLB is very easy to extend tomultiple leaky buckets so that further servicedifferentiation can be achieved.

作者： Zhen Ji Weiwei Xiao Jianhua Wang Jihong Zhang Faculty of Information Engineering, Shenzhen University, Shenzhen, China

In this paper, a scheme following the second generationwatermarking (2GW) paradigm is proposed. The hostimage is decomposed with the wavelet packet (WP). Thebit stream of binary watermark is coded into severalpatterns with salient feature, which is circular masking inthis paper. These patterns are embedded into waveletpacket coefficients according to human perceptualcharacteristics. For the detection of watermark, thegeometric distortion is calibrated for the contaminatedwatermarked image. A new HVS mask based on wavelettransform is proposed with consideration of local texturecharacteristics when embedding. Hough transform is usedto detect the circular features in the WP domain. Thisscheme has the following characteristics: (a) robustnessagainst the common geometric attacks (rotation, scaling,etc.) is improved significantly. (b) human perceptualcharacteristics is taken into consideration, therefore, thetradeoff between invisibility and robustness is *** of extensive experiments indicate that thisproposed scheme is significantly effective in resistingvarious attacks such as adding noise, rotation, scaling,JPEG compression, etc.
