1. 26. Application and Development of Optical Soot Diagnostic Techniques

   Författare :Ted Lind; Förbränningsmotorer; []
   Nyckelord :Soot; Soot diagnostics; Soot oxidation; Extinction Imaging; Soot thermometry; Optical diagnostics;

   Sammanfattning : Internal combustion engines (ICE) have been a vital part of society ever since their inception more than a hundred years ago. While initially it seemed as if the replacement of horse and carriage had solved the issue with pollutant emissions, it became evident in the 60’s that emission from ICEs is a major concern. LÄS MER

3. 27. Metal fusion using pulsed GasMetal Arc : Melt pool modellingand CFD simulation

   Författare :Pradip Aryal; Isabelle Choquet; Muriel Carin; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas metal arc; Electromagnetic force modelling; Free surface deformation; Computational Fluid Dynamics; OpenFOAM; Gasmetallbågsvetsning; Svetsläge; Elektromagnetiskkraftmodellering; Smältytans rörelser; Computational Fluid Dynamics; OpenFOAM; Production Technology; Produktionsteknik;

   Sammanfattning : Pulsed gas metal arc is a highly efficient technique used in manufacturing processes like welding and additive manufacturing. It offers high productivity and cost benefits but it is also prone to defect formation when process parameters are not properly controlled and optimized. LÄS MER

4. 28. Augmenting the Remote Control : Studies in Complex Information Navigation for Digital TV

   Författare :Aseel Berglund; Sture Hägglund; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; remote control; digital TV; paper-based TV guides; speech interaction; speech interfaces; Computer science; Datavetenskap;

   Sammanfattning : The transition to digital TV is changing the television set into an entertainment as well as information supplier device that provides two-way communication with the viewer. However, the present remote control device is not appropriate for navigation through the huge amount of services and information provided by the future digital TV, presumably also a device for accessing the Internet.

5. 29. Bringing Augmented Reality to Mobile Phones

   Författare :Anders Henrysson; Anders Ynnerman; Kari Pulli; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile Phone; Augmented Reality; HCI; Ubiquitous Computing; 3D Interaction; Computer Vision; Image analysis; Bildanalys;

   Sammanfattning : With its mixing of real and virtual, Augmented Reality (AR) is a technology that has attracted lots of attention from the science community and is seen as a perfect way to visualize context-related information. Computer generated graphics is presented to the user overlaid and registered with the real world and hence augmenting it. LÄS MER
