In this algorithm, first, the PSO algorithm is used to train the FNN. Second, when the particle swarm is trapped into local minima or loses its diversity, each particle in the swarm and its best position (Pb) are interrupted by a random function in order to improve the diversity of population, and the best position (Pg¬) of all particles remains unchanged. Third, the PSO algorithm with the new population is used to search the better global optimum. The proposed algorithm improves the diversity of the swarm and has good convergence performance. Finally, the experimental results are given to verify the efficiency and effectiveness of our proposed learning algorithm.","PeriodicalId":308774,"journal":{"name":"2009 Second International Symposium on Intelligent Information Technology and Security Informatics","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124374211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the contents and mode of information, it includes track and traceability within certain phase and that between phases. Tracking within a certain phase is to determine the business key points by analysis of meat production process and identify them by 1-d and 2-d mixed bar code and layer data identification method. While traceability is to embed the 1-d bar code of various business key points into the 2-d code to cover the whole production lifecycle backwardly. The track and traceability between phases is to realize the seamless connection and information sharing of physically-distributed and formally-isomerous meat product data based on the Web services technology, so that the user can operate logically on an integrated interface. On such base, an evolvable track and traceability system applicable to meat production is designed and realized.","PeriodicalId":308774,"journal":{"name":"2009 Second International Symposium on Intelligent Information Technology and Security Informatics","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130781948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two kinds of pipelines. One is for double-precision or single-precision floating point numbers transform into integer numbers and other is for integer numbers transform into double precision or single-precision floating point numbers. In this method hardware cost was reduced through double-precision floating point numbers and single-precision floating point numbers sharing one data path. Shifting and rounding was simplified through setting the initial value of exponent. Special numbers were also discussed and corresponding signals were defined in this method. The leading zero detection method for this method was described and a leading zero detection unit for 32-bit numbers was designed. A module of the pipeline design method proposed in this paper was designed with VHDL and EP2C35F484C6 is the target device of implementation. The source utilization and maximum frequency of this module were estimated. The simulation results were discussed. The quality of this method was confirmed by these results.","PeriodicalId":308774,"journal":{"name":"2009 Second International Symposium on Intelligent Information Technology and Security Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129580000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even HSDPA supports up to 10 Mbps data rate through HS-DSCHs (High Speed-Downlink Shared Channels), an UE (User Equipment) suffers from significant handover latency since HSDPA standard does not supporting soft handover. Therefore, in this paper, we propose a new soft handover mechanism for HSDPA to reduce the handover latency by utilizing DCH (DedicatedChannel) instead of HS-DSCH. Simulation results show that the proposed soft handover mechanism reduces the packet IAT (Inter Arrival Time) less than 15 msec while HSDPA’s hard handover suffers from 190 msec packet IAT. It means that the proposed mechanism guarantees the minimum packet IAT requirement of the typical VoIP service in 20 msec. Furthermore, the proposed mechanism employees no service disruption for the data connection while an UE performs the soft handover procedure.","PeriodicalId":308774,"journal":{"name":"2009 Second International Symposium on Intelligent Information Technology and Security Informatics","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123554207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
