Excluding the potential communication protocol overheads, a single frequency with one satellite transmits data at 0.5B/s; with the dual frequency transmission by using L1C and L2C frequencies and the parallel transmission of multiple satellites, the transmission rate can be increased to approximately 4B/s. The one-way communication of GPS is covert due to the covertness of communication channels, the occasionality of one-way communication, the disorderly distribution of information and the difficulty in recognizing and understanding communication data when the communication protocol is unknown. This paper discusses the problems of satellite rise-and-fall, data packetization and data dropout and gives solutions for them. A design paradigm for the format of newly-added L2C CNav message types is given. The GPS one-way communication has the advantages of global coverage, day-and-night and all-weather operation, as well as low cost, thus it can meet the needs for special purposes, such as civilian emergency broadcast communication, military submarine command system and command of intelligence collection.","PeriodicalId":269403,"journal":{"name":"2009 International Conference on Computer Technology and Development","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129706398","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}

Combined with process characteristics of the tower, an adaptive correction method with three deviations is proposed, which based on the recursive PLS. The predictive ability of this soft-sensing method gives accurate predictions of both measured and unmeasured quantities, even in the presence of large unmeasured disturbances. The application results show that this model has a high accurate property. The proposed method also provides a case study to aid in applications to other industrial problems.","PeriodicalId":269403,"journal":{"name":"2009 International Conference on Computer Technology and Development","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130972277","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}

It has been shown that neural network can detect smaller shifts better than statistical control charts. However, nearly all studies in this area assume that the in-control process data in the control charts follow a normal distribution. In our study, we focus on the effects of heavy tailed distributions on the performance of neural network based control chart and statistical control charts. Statistical control charts like Shewhart X control chart, Exponentially Weighted Moving Average (EWMA) control chart and Cumulative Sum (CUSUM) control chart are presented to make the comparison of the effects of heavy tailed distribution with Neural network based control chart. The criterion to compare the performance of both types of control charts is the average run length (ARL). From the results, the neural network is less robust than the statistical based control charts in the presence of heavy tailed data.","PeriodicalId":269403,"journal":{"name":"2009 International Conference on Computer Technology and Development","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128123534","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}

In this work, we introduced a graph partitioning method to partition protein interaction network into several clusters of interacting proteins that share similar functions called functional modules. Our proposed method encompasses three major steps which are preprocessing, informative proteins selection and graph partitioning algorithm. We utilized the protein-protein interaction dataset from MIPS to test the proposed method. We use Gene Ontology information to validate the biological significance of the detected modules. We also downloaded protein complex information to evaluate the performance of our method. In our analysis, the method showed high accuracy performance indicates that this method capable to detect highly significance modules. Hence, this showed that functional modules detected by the proposed method are biologically significant which can be used to predict uncharacterized proteins and infer new complexes.","PeriodicalId":269403,"journal":{"name":"2009 International Conference on Computer Technology and Development","volume":"89 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126114006","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}

This unorganized data need to handle on the way to represent a piecewise of 3d object which is able to produce a smooth surface at the crease and boundary. Various methods have been purpose for subdivision scheme, but none of this method capable to produce a good sharp feature such as darts, creases and corner. A butterfly subdivision surface is an interpolating scheme and is a good approach for a reconstruction of an unorganized point. This scheme is capable to produce an effective multiresolution representation for a piecewise smooth surfaces.
