Abstract Analysis of cultural heritage by non-destructive testing methods allows conducting an examination the building while preserving its authenticity and integrity, as well historical artistic values. As material this study, Sivas Congress Museum, which witnessed a very important event in history country, was discussed. The aim study is to determine stone type, deterioration, hardness, stre...

This paper explains non-linear non-destructive evaluation of concrete aimed at examining the occurrence of non-linearity under non-linear wave propagation through the concrete. Standard cubic concrete sections in damaged and undamaged conditions were investigated. The specimen was first damaged under compression testing and then subjected to non-linear ultrasonic evaluation in two directions i....

Neutron scattering techniques, such as neutron diffraction, small angle neutron scattering and neutron reflectometry consist very powerful tools for the non-destructive study of materials. At the Greek Research Reactor, GRR-1, a number of neutron scattering methods are employed and developed. In the present contribution, a short description of the methods and facilities is given, as well as som...

6 Common techniques to monitor the quality of fruit at the time of harvest and in storage typically rely on destructive methods to measure physical properties such as firmness and hydration. The complex, inhomogeneous composition of most fruit mean that non-destructive ultrasonic methods for quality evaluation of fruit has typically been unsuccessful. A novel ultrasound method was developed whi...
