Organisations use new technology as a strategic tool which help create new ways of satisfying customer needs and working practices. Developments in internet technologies have led to the growing dependence on web-based technologies and more recently, collaboration software platforms. In spite of the vast amount of literature which describes the benefits organisations may reap through the use of these technologies, there is also skepticism regarding the adoption of these tools. This paper takes a critical look at the adoption of collaboration tools, focusing on social media, in the enterprise especially looking at the reason for skepticism in adopting these tools. Through surveys carried out amongst users of social media and case studies, the research looks at the value adding capabilities of social media in business, the challenges and opportunities, and adoption issues.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126970319","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 practice, combinations of UEMs have been applied in a rather ad hoc manner resulting in inadequate analyses of rich usability data sets. While the potential offered by recent advances in technologies such as eye tracking for usability is recognized, and the challenges of evaluating complex web systems such as portals which involve different interaction styles are highlighted, the issue of effectively integrating multiple UEMs to make sense of observations has emerged. This paper presents a framework developed for effectively integrating UEMs in usability evaluations by matching the methods' capabilities and limitations with a classification of usability problems. The framework is applied to evaluating the usability of the Mawhiba web portal with target user populations which demonstrates how better coverage of usability issues can be achieved.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"25 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":"114713272","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}

Social networks provide means for enterprises to capture and expose many informal connections between their stakeholders. In this paper, we discuss how social networks could sustain growth and unfold business opportunities in modern enterprises. Furthermore, we study various types of social networks and investigate metrics that measure their value-added to enterprises. In response to business-oriented social network requirements, we propose a multi-tenant architecture to develop Social-Networks-as-a-Service (SNaaS) and allow efficient use of server resources while reducing maintenance costs and providing a high degree of customization to support each enterprise's requirements.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"22 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":"131171096","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 more available a computer system is, the more value it can provide to its users. In many cases high availability (HA) requirement becomes as critical as high performance. Cluster computing has been attracting more and more attention from both the industrial and the academic world for its enormous computing power and scalability. High availability features need to be included to ensure that cluster computing environments can provide continuous services. In order to validate and compare the different techniques, it is often necessary to build models of the system. A typical availability modeling method is based on analytical formalisms such as fault tree, Markov chains, Stochastic Petri Net, etc. In this paper we describe (1) a two-component cluster configuration, and (2) an availability model of that system using Markov modeling techniques.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"50 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":"133226764","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 paper we present how social network analysis can be used in order to improve software project control. The presented model is based on meta-networks where basic project entities are combined for representing communication, collaboration, and knowledge.

The scarcity of spectrum is not due to its rareness; it is mainly due to its inefficient utilization. Cognitive radio is a promising solution to this problem. It is, ideally, an intelligent radio which senses the spectrum and opportunistically transmits if the sensed band happens to be idle. Spectrum sensing by far is the issue of paramount importance in cognitive radio realm. Many schemes have been proposed for spectrum sensing, but still there is a lot of room for efficient algorithms. One of the demerits of the past research work on spectrum sensing is that if some algorithm decreases the number of sensing bits to the central receiver then the sensing performance is also degraded simultaneously. This study mainly focuses on comparing the performance of a censoring method to decrease the bandwidth of control channel in Rayleigh and Rician fading channels.","PeriodicalId":288593,"journal":{"name":"2009 International Conference on the Current Trends in Information Technology (CTIT)","volume":"7 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":"132084940","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}
