  3. 42. Multi-objective CFD-based design method for axial compressors

    Författare :Lars R Ellbrant; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Q3D; Turbomachinery; Design; Meta-modeling; Optimization; CFD; Validation; Compressor; Transonic;

    Sammanfattning : Economic aspects such as reducing specific fuel consumption and ever growing environmental requirements on emissions and perceived noise levels are the major incentives in the pursuit to improve aircraft engines. The overall efficiency of the engine is a combination of propulsive efficiency and thermal efficiency. LÄS MER

  5. 44. Towards a methodology for integrated design of mechatronic servo systems

    Författare :Fredrik Roos; Jan Wikander; Hans Johansson; Hendrik van Brussel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechatronics; Servo Systems; Design Methodology; Integrated Design; Construction engineering; Konstruktionsteknik;

    Sammanfattning : Traditional methods for mechatronics design are often based on a sequential approach, where the mechanical structure is designed first, and then fitted with off-the-shelf electric motors, drive electronics, gearheads and sensors. Finally a control system is designed and optimized for the already existing physical system. LÄS MER

  7. 45. Mixed Effects Modelling and Optimal Design of TNFα Response in LPS Challenge Studies - Methods and Applications in Drug Discovery

    Författare :Julia Larsson; Chalmers tekniska högskola; []

    Sammanfattning : ''Endotoxin and mycoplasma are Nature’s darkest secrets. If they are ever solved, Hell itself will open.'' - Lewis Thomas* Endotoxin, or lipopolysaccharides (LPS), are heterogeneous components from the cell wall of Gram-Negative bacteria and a common challenger in the field of drug discovery.
