This will result into novel business models where services compose together hierarchically in a producer-consumer manner to form service chains of added value. Service Level Agreements (SLAs) are defined at various levels in such a hierarchy to ensure the expected quality of service for different stakeholders. Automation of service composition directly implies the aggregation of their corresponding SLAs. Aggregation of hierarchical SLAs leads to cross-enterprize business networks such as Virtual Enterprize Organizations (VEO), Extended Enterprizes and Value Networks. During the hierarchical aggregation of SLAs, certain SLA information pertaining to different stakeholders is meant to be restricted and can be only partially revealed to a subset of their business partners. Based on our notions of SLA Choreography and SLA-Views, we formally define an aggregation model to enable the automation of hierarchical aggregation of Service Level Agreements. The aggregation model leads to the discovery of various aggregation patterns in context with service composition and business collaboration.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115494453","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 then introduces a new concept of Failure Signaler Oracle and presents a consensus protocol that makes use of that oracle to shield the end users from problems afflicting known consensus protocols. Our protocol allows the performance of the resulting consensus service to be decided solely, as in many other e-Services, by the prevailing communication delays and having to cope with real failures. We show how traditional method of introducing redundancy can be used to implement Failure Signaler. It is suggested that minor changes in the protocol design can improve degree of fault-tolerance of the consensus service.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132317042","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}

Results demonstrate that CGPANN has the potential to generate neural architecture and parameters in substantially fewer number of evaluations in comparison to earlier neuroevolutionary techniques. The power of CGPANN is its representation which leads to a thorough evolutionary search producing generalized networks. This opens new avenues of applying the proposed technique to any non-linear and dynamic problem.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129089261","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}

According to the vision of Wireless World Research Forum (WWRF), there will be 7 trillion wireless devices serving 7 billion people by the year 2017. Ubiquitous access to information anywhere, anytime and anyhow at low cost is one of the essential features of future mobile communication networks, which will interconnect a heterogeneity of various systems and be much more dynamic and flexible in terms of changes in access technology, topology, services, etc. Moreover, there will be a need to match resources supply with application demands as these demands are expected to fluctuate over time. This makes an adequate service placement in such networks of a major importance. In this paper we survey the existing service placement mechanisms and present a qualitative comparison of existing mechanisms. Moreover we also highlight the short comings of existing approaches so that the new approaches can remove the short comings of existing approaches.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128772349","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}

They use molecules to encode and transmit the information instead of electromagnetic, optical or acoustic waves, opening up a wealth of new solutions for several applications in biomedical, industrial and military fields. Due to certain limitations, traditional communication technologies are not suitable for nanoscale networks. Hence, nanoscale networks require new solutions such as molecular protocols, molecular channel models, and molecular transceivers for their realization. In this paper, first the concepts of molecular and nanoscale communication are explored by comparing nanoscale networks to traditional networking technologies. Later, the molecular communication, its components, communication phases, and transport methods in a biological system are explained. Then, the process of engineering nanoscale communication networks using molecular communications is discussed along with some of their interesting applications. Moreover, the short and long-range communication scenarios for the nanoscale communication networks are presented and in the end, the current developmental work and open research issues in the area of nanoscale communication networks are highlighted.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133815959","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}

Interactive user generated contents like blogs, become a popular means to voice ones opinion related to anything. The blogosphere contains a lot of user's generated contents, a growing readerships and ever increasing thoughts followers. Identifying influential bloggers is a recently introduced phenomenon; influential bloggers have prospects in bringing a great value to business. They can convince their fellow bloggers on variety of grounds, react to the news event and bring a three sixty degree view of the news, create a new thought or perception and can get people under their discernment by their power of thought and content creation. There are many researchers that proposed influential bloggers mining systems, but all these systems suffer from drawbacks like: domain driven, generalized shallow influential measure and validation and verification. We propose in this paper, an effective algorithm to identify influential bloggers by using influence measuring factors. These factors are based on contents semantics of their blog-posts, quantitative analysis of the contents and fellow readerships with their comments on the post. We applied this algorithm, on a subset of political blogosphere of Pakistan, where we have successfully able to indentify influential bloggers; proactive spreads of their influential thinking, and changing views of the fellow readers. We believe that this algorithm can be extended to identify an influential group in groups' blogging.","PeriodicalId":434420,"journal":{"name":"International Conference on Frontiers of Information Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134049270","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}
