1. 41. Playing with Context : Explicit and Implicit Interaction in Mobile Media Applications

   Författare :Maria Håkansson; Lars Erik Holmquist; Oskar Juhlin; Eric Paulos; Stockholms universitet; []
   Nyckelord :context; human-computer interaction; interaction design; mobile media; play; ubiquitous computing; Man-Machine-Interaction MMI ; människa-maskin-interaktion mmi ;

   Sammanfattning : This thesis contributes with insights into how aspects of the surrounding physical and social context can be exploited in the design of mobile media applications for playful use. In this work, context refers to aspects of the immediate surroundings – outside of the device – that can be identified and measured by sensors; for instance environmental aspects like sound, and social aspects like co-located people.

3. 42. Strength of Sandwich Panels Loaded in In-plane Compression

   Författare :Anders Lindström; Dan Zenkert; Stefan Hallström; Per-Lennart Larsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich; in-plane compression; energy absorption; debond; postbuckling; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : The use of composite materials in vehicle structures could reduce the weight and thereby the fuel consumption of vehicles. As the road safety of the vehicles must be ensured, it is vital that the energy absorbing capability of the composite materials are similar to or better than the commonly used steel structures.

4. 43. Structure and properties of Vasa oak

   Författare :Jonas Ljungdahl; Lars Berglund; Magnus Burman; Per Hoffmann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oak; archaeological wood; European oak; transverse anisotropy; Materials science; Teknisk materialvetenskap;

   Sammanfattning : The Vasa ship is not adequately supported. Measurements of the hull show that the ship deforms and rotate towards the port side. In addition, damages on the hull at support areas have been observed. The damages are due to high compressive loads. LÄS MER

5. 44. Analysis of drying wood based on nondestructive measurements and numerical tools

   Författare :Jonas Danvind; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träfysik; Wood Physics;

   Sammanfattning : Improved understanding of moisture and mechanical behaviour is a general objective for wood drying research. The main objective of this doctoral thesis was to develop nondestructive experimental methods suitable for collecting valuable response data related to the moisture behaviour and mechanical behaviour of drying wood and to refine this information into modelling parameters.

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

   Författare :Rickard Olsson; Alexander Kaplan; John Powell; Jan Frostevarg; Michael Zäh; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; monitoring; Signal processing; laser texturing; texture analysis; Produktionsutveckling; Manufacturing Systems Engineering;

   Sammanfattning : This thesis can be conveniently divided into three sections as follows;Part I. Monitoring of laser welding In laser materials processing there has always been a need for suitable methods to supervise and monitor the processes on-line, to ensure correct production quality or to trigger alarms when failures are detected.
