  1. 16. Slab track optimisation considering dynamic train–track interaction

    Author : Emil Aggestam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Genetic algorithm; Slab track; Transition zones; Dynamic vehicle–track interaction; Optimisation; Measurement; Ballastless track;

    Abstract : Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. READ MORE

  2. 17. Design optimisation of aeroengine compressor blades

    Author : Jörgen Burman; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Optimisation of multistage axial compressors is a time-demanding challenge in large need of effective methods. Traditionally, the design has been based on "trial-and-error" procedures, which count on the skills and experience of the designer to suggest redesigns that are likely to yield improvements.

  3. 18. Experimental Designs at the Crossroads of Drug Discovery

    Author : Ing-Marie Olsson; Svante Wold; Johan Gottfries; Michael Sjöström; Bo Nordén; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; Design of experiments; Experimental design; Multivariate data-analysis; D-optimal design; 96-well technology; Drug discovery; Assay optimisation; QSAR; Organic chemistry; Organisk kemi;

    Abstract : New techniques and approaches for organic synthesis, purification and biological testing are enabling pharmaceutical industries to produce and test increasing numbers of compounds every year. Surprisingly, this has not led to more new drugs reaching the market, prompting two questions – why is there not a better correlation between their efforts and output, and can it be improved? One possible way to make the drug discovery process more efficient is to ensure, at an early stage, that the tested compounds are diverse, representative and of high quality. READ MORE

  4. 19. On Evaluation of Design Concepts : Modelling Approaches for Enhancing the Understanding of Design Solutions

    Author : Micael Derelöv; Mats Björkman; Anders Warell; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This dissertation embraces the issue of evaluating design concepts. Being able to sort out the potential“best solutions” from a set of solutions is a central and important part of the design process. READ MORE

  5. 20. Simulation-Driven Design of Complex Mechanical and Mechatronic Systems

    Author : Johan Wall; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust system; Experimentation; Machine tools; Mechatronics; Optimisation; Product development; Prototyping; Simulation; Structural dynamics;

    Abstract : Effective and efficient product development is critical to business success on the increasingly competitive global market, and simulation has proven to support this in many sectors. The aim of this thesis is to study how properties of complex mechanical and mechatronic systems can be more efficiently and systematically predicted, described, assessed and improved in product development.
