Dutton (1993) presents a further HEAPSORT variant called WEAK-HEAPSORT, which also contains a new data structure for priority queues. The sorting algorithm and the underlying data structure are analyzed showing that WEAK-HEAPSORT is the best HEAPSORT variant and that it has a lot of nice properties. It is shown that the worst case number of comparisons is ndlog ne 2 ne + n dlog ne n log n+ 0:1n...

| We investigate the performance implications of providing transaction atomicity for rm-deadline real-time applications operating on distributed data. Using a detailed simulation model, the real-time performance of a representative set of classical transaction commit protocols is evaluated. The experimental results show that data distribution has a signiicant innuence on real-time performance a...

This paper presents a very general technique for the implementation of mergeable priority queues. The amortized running time is O(log n) for DeleteMin and Delete, and (1) for all other standard operations. In particular, the operation DecreaseKey runs in amortized constant time. The worst-case running time is O(log n) or better for all operations. Several examples of mergeable priority queues a...

developing of mobile technologies in the field of health create a new branch of e-health called mobile-health. the goal of this study is evaluation of communications infrastructure for mobile-health. for this purpose, fuzzy analytic hierarchy process is used for modeling and ranking the criterions and applications. three main criteria in mobile communication network namely, data transmission, a...

failure mode and effects analysis (fmea) is a method based on teamwork to identify potential failures and problems in a system, design, process and service in order to remove them. the important part of this method is determining the risk priorities of failure modes using the risk priority number (rpn). however, this traditional rpn method has several shortcomings. therefore, in this paper we p...

the failure mode and effects analysis (fmea) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. one important issue of fmea is the determination of the risk priorities of failure modes. risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. in this study, we applied...

with demand for health services continuing to grow as populations age and new technologies emerge to meet health needs, healthcare policy-makers are under constant pressure to set priorities, ie, to make choices about the health services that can and cannot be funded within available resources. in a recent paper, smith et al apply an influential policy studies framework – kingdon’s multiple str...
