Smart cards are being integrated into a diverse range of industries: ranging from banking, telecom, transport, home/office access control to health and E-passport. Traditionally, cardholders are required to carry a smart card for each application. However, recent developments in the Near Field Communication (NFC) have renewed the interest in multiple applications for different services on a sin...

This white paper provides a technical overview of the Red Hat Cluster Suite layered product. The paper describes several of the software technologies used to provide high availability and provides outline hardware configurations. The paper is suitable for people who have a general understanding of clustering technologies, such as those found in Microsoft Windows 2000 Advanced Server and Sun Clu...

We discuss analytic procedures for evaluating the availability of parallel computer systems comprised of P processors with N tasks subject to failures and repairs. In addition, we argue, via analytic and numeric examples, that not incorporating the task-stream into the model is an inadequate approach for evaluating system performance.

The purpose of this study was to determine whether undergraduate pedodontic programs currently have enough patients to meet adequately the training needs of their dental students. Indications are that many schools are experiencing declines in patient availability but information on the extent of the problem, why the problem exists, methods to alleviate it, or how it is affecting the training of...

John Wiley & Sons has announced the availability of the Encyclopedia of Medical Devices and Instrumentation, Second Edition. The senior editor is John G. Webster and one of the associate editors is Edward S. (Ned) Sternick; a medical physicist with numerous years of experience in the field. The unusual approach of announcing the availability of the six volume reference rather than reviewing it ...

This study proposes a systems-level approach to airport and runway availability assessments and prediction, and addresses the problem of the aging or continuously degrading aviation infrastructure. Although the availability block diagrams are often used in the availability assessment of aerospace and electronic systems, their application to the airport availability problem on a systemlevel, dev...

The chapter studies how to provide clients with access to a replicated object that is logically indistinguishable from accessing a single yet highly available object. We study this problem under two different models. In the first, we assume that failures can be detected accurately. In the second we drop this assumption, making the model more realistic but also significantly more challenging. Un...

In this paper, we explore new failure models for multi-site systems, which are systems characterized by a collection of sites spread across a wide area network, each site formed by a set of computing nodes running processes. In particular, we introduce two failure models that allow sites to fail, and we use them to derive coteries. We argue that these coteries have better availability than quor...
