What has been standard production resource usage and capacity management practices for most mainframe shops is not in common practice in many UNIX based distributed processing shops. There are several reasons why the UNIX shops, while running on the hottest architectures and latest graphical user interfaces, have been the "backward cousins" in relation to the mainframe shops in this area. The f...

The commercial bait trade is one pathway for aquatic invasive species (AIS) introductions, as non-target bait species can be accidentally sold to anglers who either inadvertently or intentionally release them while fishing or as excess bait. Prevention of AIS introductions via the bait trade requires a two-tiered management approach, which includes both regulation of the bait industry and angle...

Abstract Distributed manufacturing is the mainstream model to accelerate production. However, heterogeneous production environment makes engineer hard find optimal scheduling. This work investigates energy-efficient distributed permutation flow scheduling problem with flexible machine speed (DHPFSP-FMS) minimizing makespan and energy consumption simultaneously. In DHPFSP-FMS, local search misle...

Run statistics about a sequence of independent geometrically distributed random variables has attracted some attention recently in many areas such as applied probability, reliability, statistical process control, and computer science. In this paper, we first study the mean and variance of the number of alternating runs in a sequence of independent geometrically distributed random variables. The...

Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conve...

OBJECTIVES To assess the knowledge and behaviour of researchers regarding criteria for authorship, and the practices of ghost and gift authorship. DESIGN Semidirective interviews of senior clinical researchers. SETTING University hospital. PARTICIPANTS Thirty-nine main investigators of clinical research programmes. MAIN MEASUREMENTS Awareness and use of International Committee of Medica...

This paper addresses minimizing the makespan of the distributed permutation flow shop scheduling problem. In this problem, there are several parallel identical factories or flowshops each with series of similar machines. Each job should be allocated to one of the factories and all of the operations of the jobs should be performed in the allocated factory. This problem has recently gained attent...
