The increasing interest towards intelligent systems has led to a demand for the development of zero-defect strategies, with a paradigm shift from off-line and dedicated to inline metrology with integrated robotic systems. However, a major barrier preventing the systematic uptake of in-line metrology is the lack of evaluation of system capability in terms of accuracy, repeatability and measureme...

In modern textile industry, Tissue online Automatic Inspection (TAI) is becoming an attractive alternative to Human Vision Inspection (HVI). HVI needs a high level of attention nevertheless leading to low performance in terms of tissue inspection. Based on the co-occurrence matrix and its statistical features, as an approach for defects textile identification in the digital image, TAI can poten...

Nowadays precast concrete elements are widely used in buildings, bridges, and other civil infrastructure facilities because precast elements allow rapid construction and high precision quality control. However, the quality inspection of precast concrete elements primarily relies on manual inspection, which is time consuming and error-prone. Recently, terrestrial laser scanner (TLS) has been use...

The sources of errors associated with the measurement of nuclear radiations includethe noise associated with the radiation pulse, the dead time required for the processing of the incident radiation pulse and the pileup of pulses. In analogue processing, these errors are often downplayed leading to appreciable errors in the observed results. Some digital processors have been designed and built a...

We report system and algorithmic development for a sensing suite comprising multiple sensors for both surface and subsurface transportation infrastructure inspection where we focus on multi-modal mapping for inspection. The sensing suite contains both inspection sensors, such as a camera and a ground penetrating radar (GPR), and navigational sensors, such as a wheel encoder or a global position...

BACKGROUND Funnel plots are widely used to investigate possible publication bias in meta-analyses. There has, however, been little formal assessment of whether a visual inspection of a funnel plot is sufficient to identify publication bias. METHODS Visual assessment of bias in a funnel plot is quantified using two new statistics: the Imbalance and the Asymmetry Distance, both intended to repl...

The use of a laser range sensor in the 3D part digitalization process for inspection tasks allows very signi cant improvement in acquisition speed and in 3D measurement points density but does not equal the accuracy obtained with a coordinate measuring machine (CMM). Inspection consists in verifying the accuracy of a part related to a given set of tolerances. It is thus necessary that the 3D me...

For generalized Reed-Solomon codes, it has been proved [6] that the problem of determining if a received word is a deep hole is co-NP-complete. The reduction relies on the fact that the evaluation set of the code can be exponential in the length of the code – a property that practical codes do not usually possess. In this paper, we first presented a much simpler proof of the same result. We the...
