  2. 1. Non-Invasive Monitoring of Architectural Heritage

    Author : Jenny Hällström; Bebyggelsevård; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing; lidar; laser-induced fluorescence; documentation; hyperspectral; non invasive; non destructive; sustainable maintenance; conservation planning; monitoring; Coliseum; architectural conservation; restoration; Övedskloster; deterioration; Lateran Baptistery; stone; brick; thematic mapping; in situ; imaging; biodeteriogens;

    Abstract : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning.

  4. 2. Terahertz sensing for non-destructive characterisation of pharmaceutical tablets

    Author : Anis Moradikouchi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensing.; non-destructive; pharmaceutical tablets; Terahertz technology; frequency domain; dielectric characterisation; porosity measurements;

    Abstract : The pharmaceutical industry is shifting from conventional batch manufacturing to continuous manufacturing. To realise continuous manufacturing, it is crucial to assess the product quality of tablets at different stages of the production line. READ MORE

  5. 3. Towards Automation of Non-Destructive Testing of Welds

    Author : Patrik Broberg; Mikael Sjödahl; Anna Runnemalm; Torbjörn Löfqvist; Högskolan Väst; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; non-destructive testing; NDT; Industriell arbetsvetenskap; Industrial engineering; Experimental Mechanics;

    Abstract : All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

  6. 4. Non-destructive measurement of near-surface cracks in railheads : with focus on ultrasonic inspections

    Author : Rayendra Anandika; Jan Lundberg; Paul Wilcox; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail inspection; phased array; ultrasonic testing; eddy current testing; surface cracks; non-destructive testing; NDT; railway; condition monitoring; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Near-surface cracks in railhead that caused by rolling contact fatigue (RCF) is one of a kind rail defects that degrade rail track quality. Dependent on the trail load, the cracks can reach to severe level quickly. READ MORE
