A reliable maintenance system is critical to maintain an acceptable level of profit and competition. One of those techniques that are gaining a lot of interest in the manufacturing field is Non-Destructive Testing (NDT). In this work we propose an approach to integrate NDT into the development process of intelligent manufacturing systems. We propose an extension of ANEMONA, a multi-agent based ...

Introduction Nondestructive testing (NDT) of structures and mechanical parts is increasingly receiving attention as the need to monitor the health of aging infrastructure and quality controls on the manufacturing of mechanical parts is becoming more apparent. NDT is defined as using various tools, whether they be acoustic, electromagnetic, or thermally based, to inspect the structural integrity...

Fusion of NDT techniques has proven to increase the capability and reliability of defect detection thus improve inspection results. It can also provide solution for the limitations posed by a single NDT technique in acquiring the intended information and so achieving the required inspection efficiency. Eddy current thermography is an emerging technology in advanced NDT, which provides and alter...

The goal of this project is to develop a new NDT technique/algorithm based on Lamb waves, in which damage can be detected “without relying on past reference data.” In particular, a NDT methodology will be formulated for detecting defects such as crack, corrosion and delamination commonly found in aircraft. The proposed concept of “reference-free” damage diagnosis attempts to address some of the...

This study examined the short-term effects of neurodevelopmental treatment (NDT) on the motor performance of daily living skills in 2 girls with cerebral palsy, aged 27 and 32 months. For 12 weeks, the subjects received treatment sessions consisting of NDT followed by play, or vice versa. After each treatment of play or NDT, the subjects were videotaped performing individually prescribed dressi...

The normal distributions transform (NDT) registration algorithm often converges to a local minimum if there is a large initial transformation error. In order to improve convergence properties, a novel region growing clustering NDT (RGC-NDT) algorithm is proposed, which replaces volumetric divisions and removes discontinuities in the cost function at the voxel boundaries during the optimization ...

Automation of non-destructive testing (NDT) of engineering components and structures represents one of the strategic objectives of many industries. It enables increases in accuracy, precision and speed of inspection while reducing production time and associated labour costs in contrast to manual inspection. The use of robots can provide additional flexibility and autonomy to automated NDT. Auto...

This paper describes a project in progress under the auspices of EFNDT Task Group 3 on Quality in NDT. The project was conceived as a result of the EFNDT strategic planning exercise in 2005-6. The objective is to prepare guidelines on achieving quality in NDT to help develop a better understanding by users and purchasers of NDT services of the roles of the various measures available for control...

The numerical modeling of single frequency eddy-current phenomena based on the magnetic vector potential has been successfully applied to many NDT applications [1-3]. Despite the considerable wealth of sinusoidal eddy-current literature, the numerical modeling of pulsed eddy-currents has received little attention. Most of the recent finite element transient eddy-current NDT modeling [4,5] emplo...

Dye Penetrant Inspection (DPI) and Magnetic Particles Inspection (MPI) are two of the most commonly used Non-Destructive Testing (NDT) techniques in industry. Both techniques do rely heavily on human judgment and visual capability to identify any faults or defects on the specimen at the end of the process. Despite the fact that human plays an important role on the reliability of the NDT test re...
