In this paper we present a cloud computing environment for medical imaging which deals with the issues of scaling a traditionally single-user solution to a software-as-a-service solution. We will first introduce volume rendering for medical imaging, and the issues with volume rendering of medical images on the cloud. We will then describe our method for accelerating CPU based volume rendering o...

In a call center, service agents with diierent capabilities are available for solving incoming customer problems at any time. To supply quick response and better problem solution to customers, it is necessary to schedule customer problems to appropriate service agents ee-ciently. We developed SANet, a service agent network for call center, which integrates multiple service agents including both...

The pervasive post-adoption of on-demand software-as-a-service (SaaS) products via the Internet has provided clients with sufficient convenience and functional flexibility to rent and build the multifunctional services they require. Prior research has called for a deeper understanding of how client firms encourage the exploration of SaaS applications in the workplace. However, exploring the bes...

Client churn is a key challenge confronted by SaaS providers. Recent research in QoE suggested providers should rely on quantiles & percentiles to assess the service acceptability rate. In this article we introduce AQUAMan, an Adaptive QoE-Aware multi-agent negotiation mechanism for SaaS elasticity Management. Based on its estimation of the percentage of users finding the service acceptable and...

Future chip multiprocessors (CMPs) will be capable of deconfiguring faulty units in order to permit continued operation in the presence of wear-out failures. However, the unforeseen downside is pipeline imbalance due to other portions of the pipeline now being overprovisioned with respect to the deconfigured functionality. We propose PowerTransfer, a novel CMP architecture that dynamically redi...
