Increasing work loads, changes in the nature of data obtained from biopsies, and the use of laboratory statistics in determining financial provision for pathological services combine to enhance the value of computer generated results and indexing in histopathology. The system described here depends on an indexed file system using the Basic Plus-2 language with a PDP-11 computer and SNOP. Error ...

Consider a queue with a stochastic fluid input process modeled as fractional Brownian motion (fBM). When the queue is stable, we prove that the maximum of the workload process observed over an interval of length t grows like γ!log t"1/!2−2H", where H > 1/2 is the self-similarity index (also known as the Hurst parameter) that characterizes the fBM and can be explicitly computed. Consequently, we...

OBJECTIVE Unplanned readmission of hospitalized patients to an ICU is associated with an increased mortality and hospital length of stay. The ability to identify patients at risk, who would benefit from prolonged ICU treatment, is limited. The aim of this study is to validate a previously published numerical index named the Stability and Workload Index for Transfer in a heterogeneous group of I...

The sensitivity of tapping task to mental workload was investigated. Thirteen subjects were asked to produce 3 s intervals continuously while performing a time sharing task. The time sharing task was designed to manipulate a demand to allocate an attentional resource to one target and a demand to switch the target to which an attentional resource was mainly allocated. Results showed that produc...

Criminal investigative work entails a diverse array of tasks and responsibilities, ranging from interviewing suspects victims to managing the paperwork necessary follow-ups for each case. The present study sought evaluate workload impacts police investigators in metropolitan agency. NASA-Task Load Index (NASA-TLX), well-established human factor measure workload, was administered on 759 as quant...

PURPOSE Maximum oxygen uptake (VO2max) is known to be influenced by life-style factors, such as exercise and smoking. We aimed to further test the hypothesis that, besides these, work form also contributes to increase VO2max among workers. METHOD Three thousand six hundred and forty eight male workers with age 38.3 +/- 12.1 and 1,575 female workers with age 35.6 +/- 11.1, ranging from 20-year...

UNLABELLED The aim of this study was to assess mental workload in which various load sources must be integrated to derive reliable workload estimates. We report a new algorithm for computing weights from qualitative fuzzy integrals and apply it to the National Aeronautics and Space Administration -Task Load indeX (NASA-TLX) subscales in order to replace the standard pair-wise weighting techniqu...

A bucket brigade strategy allows workloads in warehouses to be distributed with a minimal level of managerial planning and oversight. However, the variability and uncertainty of the pick locations within a particular order or batch often results in picker blocking and subsequent losses in productivity. This study formulates an order batching model for robust blocking control of dynamic bucket b...

OBJECTIVE We evaluated a variety of non-invasive physiological technologies and a series of test approaches for examination of aviator performances under conditions of mental workload in order to provide a standard real-time test for physiological and psychological pilot fatigue assessments. METHODS Twenty-one male aviators were selected for a simulated flight in a hypobaric cabin with artifi...
