2. 16. Towards full Automation of Robotized Laser Metal-wire Deposition

   Author : Almir Heralic; Bengt Lennartson; Anna-Karin Christiansson; Giorgos Nikoleris; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser metal wire deposition; process control; process development; optical sensors; robotic weld equipment; Manufacturing engineering; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Metal wire deposition by means of robotized laser welding offers great saving potentials, i.e. reduced costs and reduced lead times, in many different applications, such as fabrication of complex components, repair or modification of high-value components, rapid prototyping and low volume production, especially if the process can be automated.

4. 17. Microfluidics in Surface Modified PDMS : Towards Miniaturized Diagnostic Tools

   Author : Sara Thorslund; Fredrik Nikolajeff; Jonas Bergquist; Elisabeth Verpoorte; Uppsala universitet; []
   Keywords : Materials science; µTAS; micro total analysis system; PDMS; poly dimethylsiloxane ; microfluidics; heparin; blood filtration; on-chip; ESI-MS; desalting; QCM-D; biocompatible; CD4; capillary flow; lab-on-chip; microfabrication; enrichment; point-of-care; hydrophilic; oxidation; Materialvetenskap;

   Abstract : There is a strong trend in fabricating miniaturized total analytical systems, µTAS, for various biochemical and cell biology applications. These miniaturized systems could e.g. gain better separation performances, be faster, consume less expensive reagents and be used for studies that are difficult to access in the macro world.

5. 18. On Aircraft Conceptual Design : A Framework for Knowledge Based Engineering and Design Optimization

   Author : Kristian Amadori; Petter Krus; Christopher Jouannet; Johan Ölvander; Ulf Sellgren; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap;

   Abstract : This thesis presents a design framework where analytical tools are linked together and operated from an efficient system level interface. The application field is aircraft conceptual design. Particular attention has been paid to CAD system integration and design optimization.Aircraft design is an inherently multidisciplinary process.

6. 19. Additive manufacturing of fused silica glass

   Author : Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. READ MORE

7. 20. Characterisation of Nonlinear Structural Dynamic Systems in Conceptual Design

   Author : Niclas S Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural dynamics; Model order reduction; Nonlinear characterisation; Multi-body dynamics; Frequency response functions; Multisines; Response classification; Driveline systems; Concept design analysis; Stepped-sine; Support vector machine;

   Abstract : The engine and driveline systems of passenger cars generates and distributes the necessary driving power and are major contributors to vehicle emissions, noise and vibrations, etc. More environmental friendly technologies under development are expected to intensify and add new comfort related problems, since most of them affect vibration sources or system damping.
