Impedance spectroscopy (IS) is a non-destructive testing (NDT) method [4,5,7] ranking in the electrical engineering measuring method group. It outputs data providing information on material electric and dielectric properties. Microscopically inhomogeneous materials are frequently used in the building industry. Unfortunately, the impedance spectroscopy results and their characterization on the b...

The old focus on using automation was simply to increase productivity and reduce costs. Today, global competition is forcing manufacturers not only to contain costs but also to improve quality of products and processes. Thus, the purpose of automation has shifted to broader issues. Highly automated processes ensure high quality on a constant level. But, increasing the degree of automation also ...

X-ray Computed Tomography (CT) allows visualisation of the physical structures in the interior of an object without physically opening or cutting it. After an introductory review of X-ray computed tomography and its applicability to industrial non-destructive testing and evaluation this paper presents details of a range of case studies where this technology has enabled non-destructive testing, ...

Various Departments of Transportation in the South-Central States and elsewhere have made extensive use Non-Destructive Testing (NDT) surface deflection bowl data. The falling weight deflectometer (FWD) test is a popular NDT-based used by transportation authorities to evaluate performance flexible pavement. Nevertheless, it rare develop method for evaluating pavement sections using FWD data fro...

Accumulators are used in lots of applications. So they are used as a pressure accumulator for quick energy supply to hold a constant pressure (equalization of leakage), for pulsation damping and as an element of suspension. We can differ between 3 types of accumulators: 1. Diaphragm Accumulator, 2. Piston Accumulator 3. Metal Bellow Accumulator. At applications with high requirements to permeat...

A whole wafer method for industrial high volume, non-destructive characterizing of extended defects is demonstrated 150 mm and 200 4H-SiC wafers. Deep learning (DL) coupled with techniques (NDT, DL-NDT) involving fast optical microscopy methods correlates industry accepted chemistry physics-based etch diffraction defect characterization. The application the DL-NDT shown to reproduce distributio...

Due to its high resolution and deep penetration depth, microwave ultrawideband radar is a promising tool for the non-destructive testing (NDT) of transportation infrastructure. Microwave radiation can also be used reconstruct dielectric properties objects therefore detect an air cavity or metallic rust in concrete. We contrast source inversion (CSI) as one most inverse scattering schemes. To re...
