Failure Finding Interval Optimization for Periodically Inspected Repairable Systems
… units, underwater devices etc. If no periodical inspection is scheduled, and a hidden failure has already occurred, severe consequences may result. Research on periodical inspection seeks to establish the optimal inspection interval (Failure Finding Interval) of systems to maximize availability …

On-line task scheduling and trajectory planning techniques for reconnaissance missions with multiple unmanned aerial vehicles supervised by a single human operator
… execute a flight plan and transmit real-time video of an unknown terrain. The main contribution of this work is the development of a system that autonomously schedules the display of video feeds such that the human operator is able to inspect each target in real time (i.e., no video data …

Application of Augmented Reality to Dimensional and Geometric Inspection
Ensuring inspection performance is not a trivial design problem, because inspection is a complex and difficult task that tends to be error-prone, whether performed by human or by automated machines. Due to economical or technological reasons, human inspectors are responsible for inspection …

Connecting the Dots between N-back, Operation Span, and Raven's Progressive Matrices
… the aforementioned three tasks as well as inspection time (a measure of perceptual speed; Fox et al., 2009) along with two measures of attentional control, the Stroop task (e.g., Spieler, Balota, & Faust, 1996) and the antisaccade task (e.g., Kane et al., 2001). Analyses revealed that …

Development of a Software Tool to Estimate Airfoil Feature Variations
… tool that analyzes the incoming raw material inspection data obtained from a Coordinate Measuring Machine (CMM) and estimates feature variation created within the manufacturing process i.e. from the raw material stage to finished stage. This tool is used not only to disposition whether a lot …

A novel compact Shearographic NDT system
… NDT system will enhance the capability of inspection during quality assurance and maintenance routines as well as reduce inspection time. Older compact Shearographic systems, which have been tested satisfactorily both under laboratory and field conditions at the NDT Laboratory at the …

Reducing the costs of bounded-exhaustive testing
… of bounded-exhaustive testing include machine time for test generation and execution (which translates into human time waitingfor these results) and human time for inspection of results. We propose and evaluate three orthogonal techniques that reduce these costs. Sparse Test Generation skips …

Deep learning for automated visual inspection of uncured rubber
… a data-driven approach to automate the visual inspection of uncured rubber tire assemblies. Images collected from a machine vision system are used to develop proof of concept predictive models to automate the visual inspection step for tread caps. The developed binary model exhibits an AUC of …

Information processing, intelligence and social learning in autism spectrum disorder
… non-social than through social routes. The Inspection Time (IT) task was used to assess processing efficiency and speed of processing, free of social demands. ITs were predicted to be significantly better than expected from standard IQ in children with ASD and ID, but not in those with ID …

Maintenance optimisation for wind turbines.
… Modelling System Failures (MSF) and Delay-Time Maintenance Model (DTMM). The MSF permits the evaluation of life-data samples and enables the design and simulation of a systems model to determine optimum maintenance activities. Maximum Likelihood Estimation is used to estimate the shape (β) …

Electromagnetic methods for measuring material properties of cylindrical rods and array probes for rapid flaw inspection
… flaw detection capability and can reduce inspection time through the use of multiple magnetic field sensing elements. A preliminary Hall array probe has been built and test with eight individual Hall sensor ICs and a racetrack coil. Electronic hardware is developed to interface the probes …

Human Computer Interaction Design for Assisted Bridge Inspections via Augmented Reality
… and evaluation of a novel tool for bridge inspections leveraging Augmented Reality (AR) and computer vision (CV) technologies to facilitate measurements. Named the Wearable Inspection Report Management System (WIRMS), the system supports various data entry methods and an adaptable …

Operating characteristics of passenger screening processes and the development of a paced inspection system
… performance measures of interest (i) the waiting time of the arriving entities, and (ii) the allocated screening resources and its utilization. Clearly, the traveling public would like a zero waiting time, while airports are limited both in terms of space and resource capital. The arrival and exit …
