Several important technological and economic trends are shaping the research on non-destructive testing techniques. They include increasing computerisation and automation, fusion of different NDT methods, new market expansions, use of the techniques as a process control tool, and a proliferation of merges, consolidations and joint ventures. Other important factors such as the development of new...

In situ resource utilization (ISRU) and automation are necessary. The logical first step of intention is to focus on our neighbor, the Moon, first. This work aims expand knowledge lunar aggregate simulant (LAS) based ilmenite rock, which available in Central Europe. Prismatic mortar samples were prepared standard sand LAS. measurements conducted using several different destructive (DT) strength...

The development of a Transmission-Line Matrix (TLM) for the simulation of ultrasound and microwave propagation in structures common in Nondestructive Testing (NDT) is described. The spatial resolution of the proposed model is better than a tenth of a wavelength. Numerical modeling was carried out for frequencies commonly used in ultrasound and microwave nondestructive testing (3.5MHz – 20GHz). ...

In this paper, an evolutionary scan-matching approach is proposed to solve optimization issue in simultaneous localization and mapping (SLAM). A rich literature has been invested direction, however, most of the approaches lack fast convergence simplicity regarding process, which should directly affect accuracy environment’s map estimated pose. It a line research that always active, offering var...

The development of methods for the Non-Destructive Evaluation (NDE) of concrete and masonry structures has made considerable progress in the past two decades. Technology and knowledge transfer from other areas such as materials testing and medicine has been the main source for innovation, supported through multidisciplinary research by scientists, technicians and support personnel. A versatile ...

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...

The main objective of the ultrasonic non-destructive testing (NDT) applications is to detect dangerous defects in the various constructions. The parameters and geometry of defects is very important information determining lifetime of constructions or components. In conventional ultrasonic NDT methods, based on the measurement of the amplitude and delay time of reflected signal are used. Such an...
