Loan negotiation is a time consuming process, requiring considerable time delays and efforts from both a lender and a borrower, and can considerably benefit from automation. Such system will provide help to bank clients in selecting bank and negotiating loan on conditions that satisfy them. In this work we use CBR and software agent approaches in design of the framework for electronic bank loan system as an alternative to existing paper-based version.","PeriodicalId":330215,"journal":{"name":"2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications","volume":"89 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128003464","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}

Structural changes and increasing demand for products and their associated services are expected to raise an exponential growth of pervasive service ecosystems in the next few years. This leads to instant collaborative organizations which involve both final consumers and business partners. As a consequence, information systems need to be interoperable. Unfortunately, existing enterprise engineering approaches and information systems technologies lack the intrinsic agility and adaptability features required by these service-based collaborative organizations. To solve this problem, we consider services as dynamic objects generated according to a particular context. We further introduce a multi-level service model by which multilevel class diagrams describe various facets of a particular service in terms of security and data interchange.","PeriodicalId":330215,"journal":{"name":"2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133238556","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 emphasis here is on exploiting the semantic relationships and assertion capabilities of OWL ontologies to assist clinicians in writing complex queries. This has been achieved using both a bottom-up and top-down approaches to build an ontology model to be the repository for complex end user queries. Relational database schemas are mapped into the newly generated ontology schema to reinforce the current domain ontology being developed. One of the key merits of this approach is that it does not require storing data interpretation, with the added advantage of even not storing database instances as part of the domain ontology, especially for systems with huge volume of data.","PeriodicalId":330215,"journal":{"name":"2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134510877","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}

A traditional seven- segment layout is used as a unistroke character input. The 7SI users enter character by crossing subset of seven segments that configures desired character. Thus, gesture recognition does not depend on pattern recognition, but only on the subset of seven segments that is crossed. For assuring high efficiency of entering, a circle in centre of each square of seven-segment layout is added as a shortcut for the characters composed in part by a circle. In order to compute 7SI speed, we have conducted a theoretical evaluation based on Fitts' Law. This study has shown that 7SI entry speed will be 27.49 words per minute.","PeriodicalId":330215,"journal":{"name":"2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134512065","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 proposed approach is based on the estimation and correction of the phase component of channel frequency response. In this way, this phase is considered while the magnitude is neglected. As will be shown, ignoring low- priority (LP) stream, we can perform demapping of HP stream, just by compensation of the phase of demodulated complex symbols. Compared with conventional channel estimation techniques, the major advantage of this technique is its simplicity and low computational complexity, but at the cost of losing LP stream. In fact, the aim is decoding and demodulation of just HP stream when hierarchical scheme is employed in the DVB-T transmitter. Simulation is performed to evaluate BER of HP stream versus channel SNR to validate the estimation method.","PeriodicalId":330215,"journal":{"name":"2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134610176","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}

Many techniques were proposed, including in-band messaging and out-of-band messaging; each of them has pros and cons. In this paper, we propose a new traceback scheme that mixes these two techniques in order to achieve the best of the two worlds. Our hybrid messaging scheme uses packet marking (an in-band messaging scheme) to include signaling information in forwarded IP packets, while out-of-band messaging is used as a complementary signaling part in the case of randomly spoofed IP packets. The evaluation of the proposed scheme against various performance metrics and through extensive simulation studies showed that the scheme is able to trace a single packet across several and even non-cooperative domains, with a reasonable amount of storage, processing and bandwidth overhead.","PeriodicalId":330215,"journal":{"name":"2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133808478","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 architecture effectively decouples the running of applications from the underlying environment, facilitating both security and opportunistic processing on transitory resources. This decoupling also promotes the ability to create multiple clones of an application for performance gains. To improve the performance of the system, fuzzy logic [E. Cox, 1955][L. Biacino and G. Gerla, 2002][C. Vasudevau et al., 1994][S. Dick, 2005] and case based reasoning (CBR) [Aamodt et al., 1994][D.

Based on AST, we will develop the algorithm and circuit of converters for quaternary and quinary systems. The Addition technique will be applied for converting from MVL to MVL-CD while Subtraction is used for reverse operation. In addition, we will develop the algorithm and circuit of DMT converter for quinary system by using delta gate elements. The division technique will be used to convert MVL to MVL-CD while multiplication will be used for the inverse conversion. At the end of this paper, a brief comparison will show the advantages and disadvantages of these methods in terms of cost and performance.
