Der Gedanke der Entscheidungsunterstützung durch externe Daten ist nicht neu, so haben beispiels­weise Wirtschaftsdienste und Marktforschungsinstitute mittlerweile eine lange Tradition. Die erfor­der­lichen Informationen aber genau zum richtigen Zeitpunkt, in der richtigen Menge und in...

Wissen und Wissensmanagement haben in der informationsbasierten Wissensgesellschaft eine immer größere Bedeutung. Das aktuelle Thema wird vor dem Hintergrund der Globalisierung im Rahmen der gegenwärtigen Finanz- und Wirtschaftskrise aus unterschiedlichen wirtschaftswissenschaftlichen...

In scheduling a large number of user jobs for parallel execution on an open-resource grid system, the jobs are subject to system failures or delays caused by infected hardware, software vulnerability, and distrusted security policy. This paper models the risk and insecure conditions in grid job...

RFID emerges to be one of the key technologies to modernize Logistics and supply chain management. In a typical RFID enabled logistics and supply chain application, there exist RFID readers to detect and identify the goods with RFID tags attached. Considering the huge amount of goods, the...

The "Grid", an initiative of the distributed computing community, offers unprecedented levels of computing power for organisations to apply to solving their business problems. Uniquely it also offers the communications infrastructure required to overcome the "tyranny of distance" observed by...

This paper reports a UK Economic and Social Research Council project that is exploring the use of Grid technologies to manage distributed data and act as a secure infrastructure for the delivery of computing power to distributed teams. The application focus used to test this infrastructure is...

The INWA Grid project connects grid resources in EPCC (Edinburgh, Scotland), Curtin Business School (Perth, Western Australia) and the Chinese Academy of Sciences (Beijing, China). The project has demonstrated the application of grid computing power to the analysis of distributed data drawn from...

The PERFORMS self-assessment scheme measures individuals skills in identifying key mammographic features on setsof known cases. One aspect of this is that it allows radiologists’ skills to be trained, based on their data from this scheme.Consequently, a new strategy is introduced to provide...

Economic scheduling needs to be considered for Grid computing environment, because it gives an incentive for resource providers to supply their resources. Moreover, it enforces efficient use of resources, because the users have to pay for theiruse. Tendering is a suitable model for Grid...
