An effective workload distribution has a prime rule on reducing the total execution time of a parallel application on heterogeneous environments, such as computational grids and heterogeneous clusters. Several methods have been proposed in the literature by many researchers in the last decade. This paper presents two approaches to workload distribution based on analytical models developed to pe...

The Federal Aviation Administration (FAA) has been increasing the National Airspace System (NAS) capacity to accommodate the predicted rapid growth of air traffic. One method to increase the capacity is reducing air traffic controller workload so that they can handle more air traffic. It is crucial to measure the impact of the increasing future air traffic on controller workload. Our experiment...

background: identifying the predisposing factors of neck and shoulder complaints and finding solutions to avoid them could improve the occupational health condition of the nurses. in this study, we aimed at determining the role of psychological and physical occupational factors in developing neck and shoulder complaints among the participants.   methods: this analytic cross-sectional study was ...

BACKGROUND Excellence in Graduate Medical Education requires the right clinical environment with an appropriate workload where residents have enough patients to gain proficiency in medicine with optimal time for reflection. The Accreditation Council for Graduate Medical Education (ACGME) has focused more on work hours rather than workload; however, high resident workload has been associated wit...

BACKGROUND GPs report the lowest levels of morale among doctors, job satisfaction is low, and the GP workforce is diminishing. Workload is frequently cited as negatively impacting on commitment to a career in general practice, and many GPs report that their workload is unmanageable. AIM To gather an in-depth understanding of GPs' perceptions and attitudes towards workload. DESIGN AND SETTIN...

Under ideal weather conditions, each en route sector in an air traffic management (ATM) system has a certain maximum operational traffic density that its controller team can safely handle with nominal traffic flow. We call this the design capacity of the sector. Bad weather and altered flow often reduce sector capacity by increasing controller workload. We refer to sector capacity that is reduc...

Many distributed real-time systems face the challenge of dynamically maximizing system utility in response to fluctuations in system workload. We present the MultiParametric Rate Adaptation (MPRA) algorithm for discrete rate adaptation in distributed real-time systems with end-to-end tasks. The key novelty and advantage of MPRA is that it can efficiently produce optimal solutions in response to...

situation awareness is an important factor in the incidence of industrial accidents. improving situation awareness may help to prevent occupational accidents. determination of factors influencing the situation awareness will help to plan and implement the measures for improving working conditions and making a safer workplace. in this study, was examined the role of work overload and sleepiness ...
