Electromagnetic recording and playback device
… resilient to impacts, minor compression, and operator error. The design has a minimal number of parts and requires limited maintenance or replacement of parts. The device is comprised of three systems: a magnetic head, transport system, and a support structure. Each of these systems is …

Automated robotics system for nuclear waste handling (hardware and software)
… robotics manipulators, which are controlled by operators outside a sealed environment. The operator's reduced vision and decreased dexterity causes slower job performance and fatigue, which ultimately leads to mistakes. These mistakes can be dangerous, expensive, and time consuming to clean up. …

Evaluation of performance graded asphalt binder equipment and testing protocol
… and industry testing. Sources of equipment and operator error were identified and documented. The underlying theories of the equipment and performance graded specifications were consolidated and documented as well.

A study of the damage accumulation process in poly(aryl ether ketone ketone) and its AS4 carbon fiber reinforced composites
… applications. These include decreased chances of operator error, and decreased processing times. The damage accumulation process was characterized using the acoustic emission method and also the drop in stiffness during flexure testing. It has been observed that the ultimate mechanical properties …

Investigation of Storytelling as a Requirements Elicitation Method for Medical Devices
… a device with poor usability may facilitate operator error, increasing the patient's risk of injury. Designers of healthcare systems and devices face a unique conundrum that has been documented in the literature (Martin, Murphy, Crowe, & Norris, 2006; Martin, Norris, Murphy, & Crowe, 2007; …

Machine Learning and Spectrum Sensing Cognitive Radio for Satcom Interference Detection
… in an autonomous fashion to reduce satellite operator error and workload. After detection has occurred, actions can be taken to mitigate the effects of the interference. Additionally, the detection method needs to be detected on-orbit to eliminate the need for extra data to be sent through the …

3D imaging in forensic odontology
… documenting bite marks with standard 2D cameras, errors in photographic technique can occur if best practice is not followed. Subsequent forensic analysis of the mark is problematic when a 3D structure is recorded in a 2D space. A 3D image capture and processing system might avoid the problems …

Modeling operator performance in low task load supervisory domains
… constant monitoring but require little to no operator interaction for prolonged periods, such as unmanned aerial systems, nuclear power plants, and air traffic management systems. This combination can potentially lower operators' workload to dangerously low levels, causing boredom, lack of …

Selecting material constituents and proportions for specific roller-compacted concrete mechanical properties
… pavements as well as significantly reducing operator error in specimen preparation. The gyratory compactor was employed in this research to evaluate several laboratory mixture proportions and constituents focusing on aggregate gradations and cementitious content as well as comparing companion …

Design and Control of a Multi-Fingered Soft-Rigid Hybrid Robotic Hand
… of the robot gripper to a glove worn by a human operator, and evaluate the usability of the hand as a teleoperation target for completing several tasks — we illustrate promising results that the compliance of the hand compensates for operator error and allows for fast completion of tasks …

Detection and Analysis of Molten Aluminium Cleanliness Using a Pulsed Ultrasound System
… inclusion type data respondent is attributed to operator error during labelling of the dataset, among several other sources of variance. It is therefore recommended that a Gage R&R be performed in order to identify sources of variation, among other improvement recommendations. From a research …

Evaluation of iohexol clearance to estimate glomerular filtration rate in normal horses
… require trained personnel and are subject to errors most often associated with improper or incomplete urine collection. Recently, tests using iohexol, a radiographic contrast agent, have been developed to estimate the GFR in human beings, pigs, sheep, dogs, cats and horse foals with results …

ELECTROSPINNING ROBOT FOR REGENERATIVE COATING OF IMPLANTS
… voltage spinning element to reduce effects of operator error. The final goal of the thesis is to test whether fiber control successfully reduces effects of fiber anisotropy in vitro and to use the enhanced fiber control mechanisms to produce scaffolds with significant anisotropy, depositing …

The development of micro-sample electrical impedance analysis for freeze-drying process development
… using electrical impedance analysis, (2) remove operator's subjectivity and allow accurate determination of critical temperature and prediction of freezing/drying rate, (3) study dielectric relaxation of ice and sugar solutions using interdigitate electrode and evaluate using electrical circuit …
