Formalizing operator task analysis
Human operators are unique in their decision making capability, judgment and nondeterminism. Their sense of judgment, unpredictable decision procedures, susceptibility to environmental elements can cause them to erroneously execute a given task description to operate a computer system. Usually, a …

Lossy compression and real-time geovisualization for ultra-low bandwidth telemetry from untethered underwater vehicles
… underwater vehicles and deliver it quickly to human operators. While tethered robots are able to communicate data to surface observers instantly, communicating discoveries is more difficult for untethered vehicles. The ocean imposes severe limitations on wireless communications; light is …

Automated ground maintenance and health management for autonomous unmanned aerial vehicles
… will become more of a burden than a benefit as human operators struggle to contend with maintenance operations for large numbers of vehicles. By creating autonomous UAV systems that can take care of themselves, human operators will be free to concentrate on higher level tasks such as using the …

Shared decision-making and control between humans and adaptive control algorithms
… division of responsibilities between supervisory human operators and adaptive control algorithms. Dynamical anomalies, such as the sudden introduction of unmodeled dynamics or time delays, present difficulties in control for both human operators and autonomous model-based control algorithms. …

Manual Control of Higher Order Systems
The theory that human operators employ internal models to aid in the control of complex dynamic systems is prevalent in the psychological and manual control literature. Yet empirical evidence and the subsequent analytical representation of such models is scarce.

Large-scale dynamic observation planning for unmanned surface vessels
… tasks to be performed without the direction of human operators, and have changed the way scientists and engineers approach problems. Because these robotic devices can work without manned guidance, they can execute missions that are too difficult, dangerous, expensive, or tedious for human …

Coordinating agile systems through the model-based execution of temporal plans
… become very costly, in terms of the number of human operators necessary to operate the plant. For example, in the case of a fleet of UAVs performing a search-and-rescue scenario, the traditional approach to controlling the UAVs involves providing series of close waypoints for each aircraft, …

Decision tree classifiers for incident call data sets
… the records incorrectly assigned a subject by human operators were used for testing. The J48 algorithm gave the best performance and accuracy, and was able to correctly assign subjects to 81% of the records wrongly classified by human operators.

Modeling human attention and performance in automated environments with low task loading
Automation has the benefit of reducing human operators' workload. By leveraging the power of computers and information technology, the work of human operators is becoming easier. However, when the workload is too low but the human is required to be present either by regulation or due to limitations …

Investigation of Noise Sources and Propagation in External Gear Pumps
… involve the systems in close proximity to human operators and passengers where noise is one of the main constraints to the acceptance and spread of this technology.

Throughput optimization of multi-agent robotic automated warehouses
… employing a fleet of robots to move shelving to human operators. Broadly, these types of systems are defined in the literature as multi-agent robotic systems. Amazon acquired Kiva Systems in 2012 to incorporate the technology into their operations. The goal of this thesis is to optimize the …

Kongming : a generative planner for hybrid systems with temporally extended goals
… such scripts are mostly hand-generated by human operators. This introduces inefficiency, puts a significant cognitive burden on the engineers, and prevents re-planning in response to environment disturbances or plan execution failure. For discrete systems, the field of autonomy has elevated …

Designing and evaluating an automation display for use with a flight envelope protection system
Complex control tasks involving human operators involve increasingly complex automation. Despite the advanced design of these systems, a disconnect between the pilot and the state of the automation can lead to confusion and potentially loss of control. Recognizing this shortcoming and its negative …

Real-time automatic machine inspection of plastic bottle closures
… removed from the production line. Inspection by human operators proved to be unreliable and subjective, and an automatic inspection system was needed. A machine vision system is capable of producing reliable and repeatable results in an environment which is unpleasant to humans. An automatic …

Factors influencing trust, reliance, performance and cognitive workload in human-agent collaboration
… they are used to alleviate the cognitive load of human operators while increasing task performance. Automated agents are present in a variety of domains, from safety critical environments to leisure-oriented activities, and more and more, they are being considered as a virtual teammate rather than …

Parametric tracking with spatial extraction across an array of cameras
… to be deployed, which presents problems for human operators. In the surveillance of a large area, the need to monitor numerous screens makes an operator less effective in monitoring, observing or tracking groups or targets of interest. In such situations, the application of computer systems …

Graph-based Approach for Anomaly Detection in Video Surveillance
… different areas for public safety and security. Human operators of modern surveillance systems are confronted with a huge amount of digital video data that needs to be monitored constantly. However, due to many limitations such as fatigue and time efficiency, human operators are not continuously …
