1. 1. Imaging and analysis methods for automated weld inspection

   Författare :Patrik Broberg; Tadeusz Stepinski; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; materials; Manufacturing and materials engineering; Produktions- och materialteknik; Experimental Mechanics;

   Sammanfattning : All welding processes can give rise to defects, which weakens the joint and can eventually lead to the failure of the welded structure. In order to inspect welds for detects, without affecting the usability of the product, non-destructive testing (NDT) is needed. LÄS MER

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

   Sammanfattning : 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.

   Sammanfattning : Att vara kritisk till våra dagars medier är en självklarhet, medan 1800-talets presspionjärer däremot har fått behålla hjältestatusen. I "Pressen i provinsen" tecknas den moderna pressens genombrott dock som en utdragen och långtifrån entydig process. LÄS MER

5. 4. Energy efficiency, district heating and waste management : essays on environmental economics

   Sammanfattning : Paper [I] investigates the energy efficiency of multi-dwelling buildings in Sweden to find out whether the ownership type matters. More specifically, we investigate whether rental apartment buildings are less energy efficient than cooperative apartment buildings and whether public ownership has a negative impact on energy efficiency.
