We propose an effective text mining system by using pattern matching method. Different stages of the design have been explained with pseudo code. We used space reduction heuristic constraints (D. Nadeau and P. Turney, 2005) which will increase the precision by reducing the number of candidate definitions and will include most of the true cases. The pattern matching method does not require training data to run as in the case of learning techniques. This will make the process simple and fast. Evaluation has been done by using three metrics - recall (measure of how much relevant information the system has extracted from text), precision (measure of how much information returned by the system is actually correct) and f-factor (combined value of recall and precision). Experimental results achieved 92% recall and 97.2% precision.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"29 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114026574","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}

The feature set is very small and simple. The features are extracted using pixel counting technique and contour following techniques. No preprocessing except binarization and thinning is done on the data. The purpose of this paper is two fold. Firstly, we explained by experiments that slant invariant and size invariant features help in developing general software, which is free from some of the pre-processing steps. Secondly, we confirm that pixel counting technique is very useful for deformed images than contour following technique. SVM and Tree classifier are used for classification.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115551390","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}

Task is submitted to a tool and the actual execution is carried out on aggregated network resources. Tools take care of scheduling, distributing sub-tasks and gathering results along with synchronization and message exchange requirements. They need initialization and synchronization routines for the submitted task. These tools also provide features like transparency, fault tolerance and load balancing. The aim of tool designers should be to provide quality performance with add on request initialization and feature provision. Initialization routines and special features provision take their own time over core distributed computing. In this paper, a tool DTM is implemented. DTM serves to achieve macro level parallelization. It may also be used for placing other distributed computing tools on a performance index, judging their start-up and performance.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"27 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113976568","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 type of algorithms are applied to gene expression data analysis to find a subset of genes that exhibit similar expression pattern under a subset of conditions. Cheng and Church introduced the mean squared residue measure to capture the coherence of a subset of genes over a subset of conditions. They provided a set of heuristic algorithms based primarily on node deletion to find one bicluster or a set of biclusters after masking discovered biclusters with random values. Masking of discovered biclusters with random values interferes with discovery of high quality biclusters. We provide an efficient node addition algorithm to find a set of biclusters without the need of masking discovered biclusters. Initialized with a gene and a subset of conditions, a bicluster is extended by adding more genes and conditions. Thus it provides facility to study individual genes, besides generating a large number of biclusters with different initializations. Biclusters with lower or higher scores within a specified limit can be generated by parameter setting. Use of incremental method of computing score makes the algorithm faster.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124464670","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}

Explicit routing of MPLS facilitates balancing the load by splitting traffic and moving from a congested part of the network to some other part in a well controlled way. To avoid harmful oscillations, splitting ratios are varied only with finer granularity steps. However, finer granularity increases the number of iterations to reach the steady state optimal solutions. To overcome this problem we are proposing an adaptive granularity algorithm for MPLS networks. A numerical method is developed to evaluate the performance of the algorithm. The results show that the link utilization and the mean delay obtained in a reasonable number of iterations are very close to the optimal values and the throughput is improved in MPLS network. The network simulator ns2 version ns2.31 is used for simulation.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123492855","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}

Multistage Interconnection Networks (MINs) are used to connect processors and memories in large scale scalable multiprocessor systems. MINs have also been proposed as switching fabrics in ATM networks in future broadband ISDN networks. A lot of research and development is reported in the area of Multistage Interconnection Networks of regular architecture, but Multistage Interconnection Networks of irregular architecture are largely ignored. Fault Tolerant Double Tree Network is a Multistage Interconnection Network of irregular architecture. In this paper a new mathematical model is proposed for performance evaluation of the buffered Fault Tolerant Double tree packet switching network under uniform traffic condition. An algorithm to implement this model is also presented and results obtained are compared with the results of simulation.

The top layer is a mobile ad hoc network of resource-rich sink nodes while the bottom layer is a network of static resource- constrained sensor nodes. The MSSSN architecture can be implemented at a lower cost with the currently available IEEE 802.11 devices that only use a single half-duplex transceiver. Each sink node is assigned a particular region to monitor and collect data. A sink node moves to the vicinity of the sensor nodes (within a few hops) to collect data. The collected data is exchanged with peer mobile sinks. Thus, the MSSSN architecture provides scalability, extends sensor lifetime by letting them operate with limited transmission range and provides connectivity between isolated regions of sensor nodes. In order to provide fault tolerance, more than one mobile sink could be collecting data from a given region or a mobile sink could collect data from more than one region. In the later half of the paper, we discuss several open research issues that need to be addressed while implementing the MSSSN architecture.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"1991 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125516100","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}
