As relational database systems become increasingly popular, there is a clear need to better understand the workload so systems can be designed or tuned more eeectively. A RElational Database Workload AnalyzeR (REDWAR) is developed to characterize the workload in a DB2 environment. This is applied to study a production DB2 system where an SQL trace for a two hour interval and an image copy of th...

Controller workload, recognized as a significant bottleneck to capacity increase in the future National Airspace System, has been researched extensively in air traffic management. Unfortunately, subjective workload has been an unreliable predictor of a controller’s ability to safely manage the traffic, leading to attempts at replacing workload with more objective metrics, such as task load (e.g...

Many people suffer from high mental workload which may threaten human health and cause serious accidents. Mental workload estimation is especially important for particular people such as pilots, soldiers, crew and surgeons to guarantee the safety and security. Different physiological signals have been used to estimate mental workload based on the n-back task which is capable of inducing differe...

Pilot workload was examined during simulated flights requiring flight deck-based merging and spacing while avoiding weather. Pilots used flight deck tools to avoid convective weather and space behind a lead aircraft during an arrival into Louisville International airport. The study examined concepts placing conflict avoidance responsibility on different combinations of pilot, controller and aut...

The purpose of this study was to determine the effects of the integration of automatic speech recognition (ASR) controls and spatial audio displays on soldier workload in noisy, cognitively demanding environments such as armored vehicles. To achieve this end, measures of mental workload were obtained in tasks in which subjects were instructed to give ASR voice commands in response to simulated ...

In gynecologic cytology, workload limits are imposed as a surrogate to limit error rates. Whether workload correlates with error rates in surgical pathology and nongynecologic cytology is not known. We reviewed and compared the disagreement and amendment rates based on blinded review for 5 pathologists with the number of cases reviewed during that same period. A total of 2,659 general surgical ...

background: coronary angiography, albeit a safe procedure, may cause serious complications especially in patients with left main stenosis (lms). this study was designed to investigate the efficacy of workload achieved by exercise tolerance test (ett) in predicting lms in candidates for coronary angiography. methods: a total of 743 patients with a positive ett who subsequently underwent cardiac ...

BACKGROUND AND OBJECTIVE Education of residents in academic medical centers occurs as part of clinical care, but little is known about the relationship between clinical workload and educational experiences among pediatric residents. The goal of this study was to assess residents' perceptions of learning on inpatient services at a children's hospital in relation to perceived workload and actual ...

attention to the physical and physiological needs of a soccer referee plays an important role in his performance in a match as in order to regulate the rules of the game, the referee should track the event and players by moving inside the pitch continually with no restriction. the aim of this research was to study the variations in workload, heart rate and blood lactate in elite soccer referees...
