  1. 1. Non-Invasive Monitoring of Architectural Heritage

    Author : Jenny Hällström; Lunds universitet.; Lund University.; [2008]
    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 : Popular Abstract in Swedish Två mobila system, ett svenskt och ett italienskt, för undersökning av historiska fasader har använts för att undersöka möjligheten till identifiering av olika material, biologisk påväxt och faktorer som i framtiden kan leda till nedbrytning av kulturhistoriskt värdefulla monument. Undersökningarna visade på möjligheter att genomföra analyser av ytor med hjälp av fluorescens från 65 meters avstånd, oberoende av tid på dygnet och årstid, och med möjligheten att kunna skanna av ytor som är svåra att nå från marknivå.

  2. 2. Towards Automation of Non-Destructive Testing of Welds

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Patrik Broberg; Högskolan Väst.; Luleå tekniska universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell arbetsvetenskap; Industrial engineering; Welding; non-destructive testing; NDT; Experimentell mekanik; 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.

  4. 4. In-situ assessment of density and material properties in timber structures by non-destructive and semi-destructive testing

    University dissertation from Stockholm : Department of Psychology, Stockholm University

    Author : Thomas Kruglowa; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray; Vasa warship.; semi-destructive testing SDT ; density determination; non-destructive testing NDT ; calibration procedure; Keywords: In-situ assessment;

    Abstract : ABSTRACTIn the assessment of timber structures, diagnostic investigations of the structural members and connections are generally necessary. The assessment often requires appropriate non-destructive testing (NDT) and semi-destructive testing (SDT) techniques. READ MORE

  5. 5. Finite Element Modelling of Eddy Current Non-Destructive Evaluation in Probability of Detection Studies

    University dissertation from Stockholm : Department of Psychology, Stockholm University

    Author : Anders Rosell; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy Current; Model Based Probability of Detection; Probability of Detection; Non-destructive Evaluation; Finite Element Modelling;

    Abstract : The goal of this work has been to evaluate the possibility to use mathematical modelling to characterize the capability and reliability of automated eddy current inspections. The safety in aerospace propulsion is critical. Components that are critical for the operation are therefore designed to withstand material degradation. READ MORE
