2. 1. Structural health monitoring of concrete structures using diffuse waves

   Author : Patrik Fröjd; Teknisk geologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; övervakning; ultraljud; betong; diffusa vågor; oförstörande provning; structural health monitoring; ultrasound; concrete; nondestructive testing; Civil engineering; diffuse waves;

   Abstract : The work presented in this thesis has aimed to investigate and implement techniques for ultrasonic measurements in structural health monitoring applications for civil structures. The focus of the work has been to make these systems practical in real applications, where the large size of the structures, and the changing environments they are exposed to, pose problems for many methods which otherwise fare well in laboratory settings.

4. 2. School Bullying and Power Relations in Vietnam

   Author : Paul Horton; Helle Rydstrøm; Jeffery Hearn; Neil Duncan; Linköpings universitet; []
   Keywords : Bullying; power; Vietnam; school; education; gender; ethnography; surveillance; normalisation; control; discipline; teachers; students; silence.; Mobbning; makt; Vietnam; skola; utbildning; genus; etnografi; övervakning; normalisering; kontroll; disciplin; lärare; elever; tystnad.; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Abstract : Taking seriously the oft-made claim that power relations are central to school bullying, the dissertation focuses specifically on the interconnectedness of school bullying and power relations within the specific context of Vietnamese lower secondary schooling. The dissertation is based on extended ethnographic fieldwork in two lower secondary schools in the north-eastern Vietnamese port city of Haiphong. READ MORE

6. 4. Data Driven Condition Monitoring for Transmission and Axles

   Author : Elisabeth Källström; John Lindström; Magnus Karlberg; Jiri Tuma; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Abstract : As the requirements to improve up-time and thus to reduce costly down-time con-tinuously increases, the construction equipment business focuses on more and newways to increase ability and sensitivity of early fault detection of critical compo-nents and parts in order to prevent failure. Failure of critical components in theheavy duty machine may lead to unnecessary stops and expensive downtime. READ MORE

7. 5. Analysis and Monitoring of Laser Welding and Surface Texturing

   Author : Rickard Olsson; Alexander Kaplan; John Powell; Jan Frostevarg; Michael Zäh; Luleå tekniska universitet; []
