In this paper, we propose and analyze DMAP-FR, a mobility and service management scheme with failure recovery (FR) control in Mobile IPv6 systems. The basic idea behind DMAP-FR is to leverage access routers (ARs) running as regional mobility anchor points (MAPs) as in Hierarchical Mobile IPv6 (HMIPv6) for mobility and service management formobile nodes (MNs). However, unlikeHMIPv6,DMAP-FR allow...

BACKGROUND Participation of patients with heart failure in cardiac rehabilitation in the UK is low. This study investigated the availability of cardiac rehabilitation services for patients with heart failure in the UK and the views of service coordinators on ideal service models. DESIGN Our study was a cross-sectional national postal survey that was mailed to 342 service coordinators in the U...

We describe the architecture, operational practices, and failure characteristics of three very large-scale Internet services. Our research on architecture and operational practices took the form of interviews with architects and operations staff at those (and several other) services. Our research on component and service failure took the form of examining the operations problem tracking databas...

This paper applies the service blueprinting method as a tool that can produce a systematic description and analysis of an industrial outsourcing service process. The key objective is to characterise critical incidents and potential failure situations from the service provider’s perspective. The main benefit of the service blueprinting technique is that it makes the service provision process, fa...

Cloud computing is a recently developed new technology for complex systems with massivescale service sharing, which is different from the resource sharing of the grid computing systems. Cloud reliability analysis and modeling are not easy tasks because of the complexity and large scale of the system. This paper systematically analyzes cloud computing and models the reliability of the cloud serv...

Many people rightly consider that failure detection should be provided as a generic distributed system service to be used to support fault-tolerance within many applications, in spite of possibly very diverse requirements. Reality is however different, as classical techniques are normally unable to cope with many distributed applications running simultaneously. To overcome this problem, we advo...

in recent years, the application of composite materials in aircraft and space vehicle structural components has become increasingly popular. preventing failure of composite structural systems has been an important issue in engineering design. due to the lack of through-the-thickness reinforcement, structures made from laminated composite materials and adhesively bonded joints are highly suscept...

This study makes a first effort to understand the factors affecting customers' decisions to invoke warranties, and to distinguish this behavior from the factors affecting customer perceptions of service quality. The study context is GTE's introduction of a warranty program as part of a telecommunications repair service for small business customers. The results suggest that customer perceptions ...
