The final outcome of a group decision making process reaches a consensus decision. However, using one particular model should not preclude the consideration of other models or other means of assessing group decision making. This study aims to provide a Delphi-based group decision model of collective intelligence. Many research mainly focus on how to attain the consensus; however, rarely further investigate the expert selection process. Hence, this work (1) furnishes a group decision process that takes into account the people from social network, (2) empowers the collective intelligence from social network, and (3) leverages the decision effort of experts.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"54 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113956534","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}

Being always connected to the network offers a solution to this problem as the server infrastructure of the service provider can substitute part of the local functionality whenever the terminal becomes overloaded. Automatic reconfigurability refers to the ability to automatically switch between local and remote services in a seamless manner whenever the conditions impose it, both at start time and run time. This paper describes the requirements and the design of a context aware middleware solution that manages the services invoked by applications. It also presents the specific programming model including the service lifecycle that enables centralized service control and efficient migration of the service state.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122641289","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}

DRX cycles limit the scheduling freedom of users and increase battery saving opportunities in the User Equipment (UE) by allowing it to turn its receiver circuitry off for some periods of time. Prior work has concentrated mainly on optimizing the usage of radio resources when small bit rate delay critical services, like VoIP, are considered. However, the battery life of small handheld devices might become a limiting factor in providing satisfactory user experience. Thus, this paper evaluates the performance also from the battery life perspective when DRX cycles together with VoIP are considered. The performance is evaluated with a fully dynamic system level tool in which the mobility of the users, radio resource management functionalities and the interactions between them are explicitly taken into account. The study indicated that the longer the DRX cycle is the higher are the battery saving opportunities but at the same time VoIP over HSDPA capacity can be compromised. Capacity degeneration in pure VoIP traffic simulations was, however, possible to be mitigated by using an adequately long inactivity timer. In mixed traffic scenarios including both VoIP and Best Effort (BE) traffic, higher cell throughput was achieved by allowing more scheduling time for BE users with adequately long DRX cycle and a short inactivity timer.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122651099","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 approvals reflect a level of endorsement by the community related to the collection and can be interpreted as trust, relevance, recommendation, and similar. They can come from perceived authorities, such as recognized experts and professional associations, or from aggregated opinions of a wider community, representing popular approval. We conducted preliminary experiments to incorporate social approval votes into search over 42,000 books by training neural networks. Using a set of 250 search topics with partial relevance judgments from non-expert users, we observe that the votes reflecting a broad appeal are most effective. We hypothesize that such sources of approval are more compatible with the general nature of the relevance judgments used in the experiments.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126204324","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}

To make the updating more meaningful and efficient, a dissectional analysis of model error which may introduce during manufacture has been carried out. The optimal objective function was constituted with both the residuals error of frequency and mode shape. The updating results indicated that when the FEM has huge number of nodes and elements, the analytical frequency can be very close to the measured value after the updating, however, the updating effect of mode shape was not obvious, because it is hard to updating the element one by one, and the measurement error of mode shape is quite large.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126375856","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 United Nations Children’s Fund (UNICEF) contends that a child who is off the birth registration radar, in comparison to a registered child, is a more attractive prospect to child traffickers, and is more likely to face discrimination and denial of access to basic life-enhancing services. Although birth registration alone does not secure access to vital social services, non-registration can further marginalise the people at the lower echelon of the society. The United Nations Children’s Fund estimates that the birth registration rate in Vanuatu for 2005 was less than thirty percent. This paper examines the extent of non-registration in Vanuatu, in order to explore whether the opportunities offered by ICT do have a role in improving the provision of birth registration services in that country. It is anticipated that the outcome of this study can be extended to other developing countries in the Pacific.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129543371","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 design of the proposed convolver utilizes approximation method with error correction technique to transform data to logarithmic domain for reduced power consumption. A novel design and implementation of a modular approach for leading bit detection module that is used to compute the binary logarithm is presented. A partitioning and gating technique is also presented to reduce the switching activities based on detection of insignificant data bits. It is observed that the proposed logarithmic-domain multiplier reduces power consumption in two common image filtering operations by more than 50% compared to conventional linear-domain 2D convolvers.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129658115","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}

Our proposed architecture takes into account the fact that GRID frameworks and their modules are not easy to modify or re-implement. It is therefore our aim to provide a plug-in which can be easily added to existing frameworks, thus avoiding significant and time-consuming modifications. Furthermore, we assume that existing scheduling algorithm in the framework should not be completely overridden, but rather modified only if there are chances, based on historical data, that the modification will yield a better result. Finally, we focus on use of off-the-shelf simple machine learning methods in a black-box manner with internal parameter optimization. We present three experiments within a simulated environment, performed with synthetic data aimed at congestion of the system. The results show that improvements over the simple scheduling algorithms can be made.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129461247","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}
