This paper explores a dual phase approach for developing network protocols: in the first phase protocols are modeled using UML (Unified Modeling Language) as the formalism, and, in the second phase, use of executable specification and prototyping of protocols based on Java is supported. The prototyping of a protocol is useful for further investigations such as verification of protocol properties, test case generation etc. Once the second phase provides a satisfied result, the developers can go ahead in developing and deploying the protocol in the real environment. Yet another objective in this work is to design executable constructs in Java to specify protocols and prototyping them. The protocols designed using this approach ensures sustenance of the models already developed. Illustration of using executable constructs in Java to specify and prototyping of protocols, and comparison with native implementations is presented in this paper.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130005123","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 core point (CP) of the input fingerprint is detected. Core point has been located in the center, the fingerprint image is cropped (A × A) around the based point. A fingerprint image is preprocessed for minutiae and core point. The core point is used to align the input image and template image. Fingerprint features such as minutiae points determination, their coordinates location, distance between base point and above minutiae points and radius of arcs for each ridge pattern based on the align fingerprint image. These above mentioned features are stored in different databases. The input fingerprint features are compared with above pre-defined database and decision will be made by voting system. We conducted evaluations on the FVC-2004 datasets and have summarized the results in the conclusion section.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134565137","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}

Since the proposed approach involves temporary interruption to link/server access, it has implications in terms of performance degradation. An analytical method is used to evaluate the cost in terms of the degradation of system performance. Unlike previous studies, the failures of the servers are considered together with link/server interruptions for renewals. Therefore the model presented considers the system for exact performability evaluation. Numerical results are provided in order to analyse the effects of renewal times, times between renewals and failures of the server.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130275332","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}

Wireless communication between the various system components is primarily done using WiFi technology. The ordering and subsequent transaction processing are done at the user end using a WiFi enabled PDA that communicates with a local server which in turn sends requests and receives confirmations from the various departments involved in processing the order. The system incorporates security features at all levels of the architecture in order to prevent unauthorized access, assign privileges to users, and maintain the integrity of the information being exchanged. The complete system was fully implemented as a prototype and its operation verified. The system architecture is highly flexible and a scalable one which enables expansion whenever the need arises.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133493000","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 research is being conducted to address the integration of cultural factors to enhance the reach of information access, which is caused by the ambiguity of cultural terminology. In this context, we study cultural differences in categorization and classification by means of card sorting experiments in combination with observations and interviews. We also investigate how different cultures view similar concepts in different ways and how these can be represented. An initial analysis of data collected in Pakistan and UK reveals a number of differences between Pakistani and British participants as to how they classify every-day objects. The differences found suggest a number of design solutions for cultural inclusion.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133507515","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 outcome of this phase is a list of matching functions. The second phase is to find correspondences between concepts of candidate ontologies. The outcome of this phase is two lists: a list of matches and a list of unrelated concepts. The third phase is merging.

But studies have proven that women are under represented in the field of technology. Research results show that the school girls are using computers and the Internet at rates similar to their male peers. But at the same time, girls are five times less likely to consider a technology-related career or plan on taking post-secondary technology classes. Therefore efforts are being taken all around the world to attract women into Information and Communication Technologies (ICT). One such endeavour was the Digigirlz day organised at the Dubai Women's College.

In order to prevent the users having to deal with unnecessary details, experts are going for languages specifically created for distributed system domain. Such systems are often considered to be complex. Assuring the correctness of these systems with traditional code reviews and testing is difficult as these verification methods deal with the high-level specification of the system. In order to prove that high-level specification is correctly implemented at the lower level, the compiler, which performs the translation, needs to be verified. Using formal methods, based on mathematics and formal logic, specification and verification have been discussed as a means of a solution. This paper identifies and analyses the available formalisms and techniques for verifying the correct operation of parallel and distributed systems.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127314161","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}

Data de-duplication can eliminate multiple copies of the same file and duplicated segments or chunks of data within those files. In these days, therefore, data de-duplication becomes an interesting field in storage environments especially in persistent data storage for data centers. Many data deduplication mechanisms have been proposed for efficient data deduplication in order to safe storage space. Current issue for data deduplication is to avoid full-chunk indexing to identify the incoming data is new, which is time consuming process. In this paper, we propose an efficient indexing mechanism for this problem using the advantage of B+ tree properties. In our proposed system, we will first separate the file into variable-length chunks using Two Thresholds Two Divisors chunking algorithm. ChunkIDs are then obtained by applying hash function to the chunks. The resulted ChunkIDs are used to build as indexing keys in B+ tree like index structure. So the searching time for the duplicate file chunks reduces from O (n) to O (log n), which can avoid the risk of full chunk indexing.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129915071","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}
