Researchers often treat workload as a task-dependent variable. To evaluate the effect of workload on individuals' performance, researchers commonly use several methods, such as varying the complexity or number of tasks that test participants are asked to handle or placing individuals under time constraints. Only rarely have researchers investigated workload as a variable dependent on individual...

There are cases in which database system benchmarks should be executed in a realistic environment to get meaningful performance results. We propose a workload generator that helps benchmarks be executed in an environment similar to the real world in terms of resource status. The workload generator can create memory-bound, CPU-bound, and I/O-bound workloads. The workload generator allows users t...

Evaluation methods for parallel computers often require the availability of relevant workload information. To this end, workload traces recorded on real installations are frequently used. Alternatively, workload models are applied. However, often not all necessary information are available for a specific workload. In this paper, a model is presented to recover an estimated job execution time wh...

Mental workload is an important component in complex human-machine systems. The limited applicability of empirical workload measures produces the need for workload modeling and prediction methods. In the present study, a mental workload prediction model is built on the basis of attentional resource allocation and information processing to ensure pilots' accuracy and speed in understanding large...

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...

This paper introduces workload-based wavelet synopses, which exploit query workload information to significantly boost accuracy in approximate query processing. We show that wavelet synopses can adapt effectively to workload information, and that they have significant advantages over previous approaches. An important aspect of our approach is optimizing synopses constructions toward error metri...
