  2. 11. A multivariate approach to QSAR

    Author : Sven Hellberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSAR; beta-adrenergic agents; haloalkanes; halogenated anesthetics; peptides; fractional factorial design; multivariate data analysis; principal components PC ; partial least squares PLS ;

    Abstract : Quantitative structure-activity relationships (OSAR) constitute empirical analogy models connecting chemical structure and biological activity. The analogy approach to QSAR assume that the factors important in the biological system also are contained in chemical model systems.The development of a QSAR can be divided into subproblems:1.

  4. 12. Aerodynamic and Aeroacoustic Analysis of a Multi-Element Airfoil using Hybrid RANS/LES Modeling Approaches

    Author : Bastian Nebenführ; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ffowcs-Williams and Hawkings; HYB0; noise; hybrid RANS LES; multi-element airfoil; CAA; Kirchhoff; Curle; high-lift;

    Abstract : Global hybrid RANS/LES simulations were used for computing the turbulent flow around a three-element airfoil. Based on the results of the flow computations, a comprehensive analysis of the flow properties was performed. READ MORE

  5. 13. Numerical Techniques for Acoustic Modelling and Design of Brass Wind Instruments

    Author : Daniel Noreland; Bertil Gustafsson; Leif Abrahamsson; Björn Sjögreen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acoustic horn; brass wind instrument; loudspeaker; optimization; hybrid method; Numerical Analysis; Numerisk analys;

    Abstract : Acoustic horns are used in musical instruments and loudspeakers in order to provide an impedance match between an acoustic source and the surrounding air. The aim of this study is to develop numerical tools for the analysis and optimisation of such horns, with respect to their input impedance spectra. READ MORE

  6. 14. Ubiquitous Cognitive Computing: A Vector Symbolic Approach

    Author : Blerim Emruli; Kai-Uwe Kühnberger; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : A wide range of physical things are currently being integrated with the infrastructure of cyberspace in a process that is creating the so-called Internet of Things. It is expected that Internet-connected devices will vastly outnumber people on the planet in the near future. READ MORE

  7. 15. Correlations in multiparticle production

    Author : Markus Ringnér; Teoretisk partikelfysik - Geonomgår omorganisation; []
