We consider a broadcast model involving multiple transmitters and receivers. Transmission is performed in rounds, where in each round any transmitter is allowed to broadcast a single message, and each receiver can receive only a single broadcast message, determined by a priority permutation over the transmitters. The message received by receiver R in a given transmission round is the one sent b...

BACKGROUND Private land conservation is an essential strategy for biodiversity protection in the USA, where half of the federally listed species have at least 80% of their habitat on private lands. We investigated the alignment between private land protection conducted by the world's largest land trust (The Nature Conservancy) and the science driven identification of priority areas for conserva...

When a distributed MPEG player system is transmitting MPEG videos over an open network, like the Internet, the system usually has no control on the network traffic. Thus, it has to look into the dynamic nature of the traffic and to adjust itself in order to provide the quality of service guaranteed to the video transmission. Transmitting multiple video streams and the different levels of qualit...

In this study, failure mode and effect analysis (FMEA), a proactive tool, was applied to reduce errors associated with the process which begins with assessment of patient and ends with treatment of complications. The aim of this study is to assess whether FMEA implementation will significantly reduce the incidence of catheter-related bloodstream infections (CRBSIs) in intensive care unit.The FM...

We present an efficient and practical lock-free implementation of a concurrent priority queue that is suitable for both fully concurrent (large multi-processor) systems as well as pre-emptive (multi-process) systems. Many algorithms for concurrent priority queues are based on mutual exclusion. However, mutual exclusion causes blocking which has several drawbacks and degrades the overall perform...

Recent progress in technology has facilitated the design, testing, and deployment of traffic signal priority strategies for transit buses. However, a clear consensus has not emerged regarding the evaluation of these strategies. Each agency implementing these strategies can have differing goals, and there are often conflicting issues, needs, and concerns among the various stakeholders. This rese...

BACKGROUND Much of the debate as to whether or not the scaling up of HIV service delivery in Africa benefits non-HIV priority services has focused on the use of nationally aggregated data. This paper analyses and presents routine health facility record data to show trend correlations across priority services. METHODS Review of district office and health facility client records for 39 health f...

This paper presents a theory of consumer subscription service, unifying priority service and dynamic pricing within a two-settlement system in ways that foster efficient risk management and competitive electricity markets. Consumer subscription service entails transactions in two time periods: a forward transaction that allows consumers to select service options to hedge financial risks and a s...

Virtual memory management has come to play an increasingly adversarial role in the scheduling of processes. While it is the job of the CPU scheduler to determine the order and length of execution of processes, its attempts to meet the desired scheduling constraints are thwarted by the memory manager under memory pressure. This is because scheduler policies like priority are not supported by mem...

This paper reviews the recent development of the formal framework of priority algorithms for scheduling problems [BNR02]; the extension of the model for facility location and set cover [AB02], and graph problems [DI02]. We pose some open questions and directions for future research.
