The purpose of this study was to determine the relationship between ambient workload and outcomes of patients in the intensive care unit (ICU). Measures of workload evaluated for each patient on each day of ICU admission were the number of new admissions, ICU census, "code blue" patients not admitted and Acute Physiology and Chronic Health Evaluation (APACHE) II scores and Multiple Organ Dysfun...

The Index of Cognitive Activity is an innovative technique that provides an objective psychophysiological measurement of cognitive workload. As users operate in increasingly complex environments, it is essential that the designers of these environments understand the cognitive demands placed on the users. The Index of Cognitive Activity (ICA) provides an important estimate of the levels of cogn...

background: the employees of welfare centers, due to the special conditions of their work, may be exposed to excessive occupational stress and workload . thus, the aim of this study was to determine the effect of workload and occupational stress on the general health of female employees of public welfare centers.   materials and methods: this was a correlational research on 63 female employees ...

We consider methods for learning vector representations of SQL queries to support generalized workload analytics tasks, including workload summarization for index selection and predicting queries that will trigger memory errors. We consider vector representations of both raw SQL text and optimized query plans, and evaluate these methods on synthetic and real SQL workloads. We find that general ...

background: the present study aimed to investigate the effects of work shifts and mental workload on chronic fatigue among female nurses in intensive care units of selected hospitals in shiraz.   methods: the participants in this cross-sectional study were 118 female nurses working in intensive care units of three hospitals in shiraz with an average age of 304.8± years. sp (samn-perelli) mental...

Many data-intensive websites are characterized by a dataset that grows much faster than the rate that users access the data and possibly high insertion rates. In such systems, the growing size of the dataset leads to a larger overhead for maintaining and accessing indexes even while the query workload becomes increasingly skewed. Additionally, the database index update costs can be a non-trivia...

Consider two M=G=1 queues that are coupled in the following way. Whenever both queues are non-empty, each server serves its own queue at unit speed. However, if server 2 has no work in its own queue, then it assists server 1, resulting in an increased service speed r 1 1 in the first queue. This kind of coupling is related to generalized processor sharing. We assume that the service request dis...
