The purpose of this investigation was to document the failure rate and length of service of crowns and fixed partial dentures (FPDs) fabricated in a Nigerian dental school. The reasons for failure of the initial restorations and their length of service were also ascertained. Also, the numbers of retainers, pontics, and the types of restoration were recorded. Poor esthetics was the most frequent...

As systems scale up, their mean-time-to-failure reduces drastically. We consider parallel servers subject to permanent failures but such that only one needs to survive in order to execute a given task. This kind of failure-model is appropriate in at least two types of systems: systems in which repair cannot take place (e.g. spacecraft) and systems that have strict deadlines (e.g. navigation sys...

Online service failures in production computing environments are notoriously difficult to debug. When those failures occur, the software developer often has little information for debugging. In this paper, we present Insight, a system that reproduces the execution path of a failed service request onsite immediately after a failure is detected. Upon a request failure is detected, Insight dynamic...

A National Service Framework for heart failure is urgently needed.

recent disclosures of failures of care in the national health service (nhs) in england have led to debates about compassion deficits disallowing health professionals to provide high quality responsive care. while the link between high quality care and compassion is often taken for granted, it is less obvious how compassion – often originating in the individual’s emotional response – can become ...

nowadays, the awareness of service firms’ managers about the crucial role of customers in the success or failure of their business has increased. this has led them to this fact that the best strategy for surviving in the marketplace is encouraging customers’ prosocial behaviors in service delivery process. reasonably, one of the best strategies to encourage customers toward these behaviors is s...

Most of today’s organizations are still far from profiting from the full potential of web service technology. Organizations invoke each other’s web services, but do hardly synchronize the life cycles of individual web services with each other. When realizing an integrated service this might cause failures and requires a governance method for synchronizing the life cycles among organizations. In...

A single server waiting line system with Poisson arrivals and Inverse Gaussian service times has been analyzed. The same model has been analyzed by using Mukherjee-Islam (1983) model as the service time model. Inverse Gaussian model has been used in queuing theory but the Mukherjee-Islam model which is basically a failure model has been tested first time as the service time model.

Internet has evolved into an indispensable service delivery infrastructure. Various application services such as multimedia services and web services have been widely deployed and used. However, due to the problems pertaining to scalability, reliability, and manageability, traditional monolithic service provision approach has become inadequate. Thus, we propose a compositional approach for prov...

AIMS AND OBJECTIVES To understand the views of patients and professionals on the acceptability and perceived usefulness of telemonitoring in the management of chronic heart failure in the context of day-to-day care provision. BACKGROUND There is an increasing interest in the potential for telemonitoring to support the home-based management of patients with chronic heart failure. However, litt...
