The Web is now evolving from information sharing to resource provisioning as the emerging Web services and Grid technologies are widely accepted and practiced. Soon the Web will be populated with abundant resources that can be accessed, shared and reused, which will inevitably lead to resource overflow. This chapter introduces a semantic-enabled, knowledge-based intelligent recommender system f...

Automatic Grid resource discovery and brokerage shields the Grid middleware complexities from the Grid users and leads towards an invisible but simple and robust Grid. Realizing this vision requires a machine understandable resource description and powerful correlation 1 mechanism. Semantic technologies like ontologies provide vocabularies with explicitly defined, unambiguously understandable a...

In recent years, the development of wireless communication technologies has made progression toward Wireless Mobile ALL-IP Network. By integrating the communication technologies, connections are provided among a great number of wireless communication networks, and users are able to select devices from different wireless communication technologies for internet access. People are no longer confin...

Workflow technologies have become a major vehicle for easy and efficient development of scientific applications. A critical challenge in integrating workflow technologies with state-of-the-art resource provisioning technologies is to determine the right amount of resources required for the execution of workflows. This paper introduces an approximation algorithm named BTS (Balanced Time Scheduli...

Currently, the casual consumer has few available resources on product security and privacy with which to inform purchasing decisions. This absence of coherent information becomes increasingly important as we incorporate an increasing level of sensors, actuators, and connectivity into the technologies in our homes. We wish to initiate a discussion on the potential utility of an organized entity ...

Low-cost, robust, and user-friendly diagnostic capabilities at the point-of-care (POC) are critical for treating infectious diseases and preventing their spread in developing countries. Recent advances in micro- and nanoscale technologies have enabled the merger of optical and fluidic technologies (optofluidics) paving the way for cost-effective lensless imaging and diagnosis for POC testing in...

Currently, the conversion of megacities into smart cities is a crucial factor in improving residents’ quality life. The goal city concept to develop urban management via use technical tools that offer latest technologies, while taking account applicable environmental standards, conserving resources, and achieving expected results. This article reviews analyses various research publications pert...

In ad hoc wireless networks (AWNs), the provision of Quality of Service (QoS) guarantees is much more challenging than in conventional wireless networks, mainly due to node mobility, multihop communications, contention for channel access and a lack of central coordination. Typically multimedia applications have delay-sensitive and high bandwidth requirements, especially for shared wireless chan...

background dynamic contrast-enhanced magnetic resonance imaging (dce - mri) has been widely used in the management of breast cancer, and its diagnostic value in breast imaging has been demonstrated. there have only been a few reports regarding the usefulness of pre-contrast imaging. knowledge about clinically significant findings of preoperative, pre-contrast t1 and t2 mr images will allow more...
