3. 17. A multivariate approach to QSAR

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

   Sammanfattning : 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.

   Författare :Mary Ingemansson; Litteraturvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Judith A. Langer; empowerment; cultural encounters; history; the Viking age; Borgen i fjärran 1998 ; Det gyllne svärdet 1998 ; Drakskeppet 1997 ; Maj Bylock; literature instruction; historical consciousness; The historical novel; the perspective of being the other; envisionment building; literature teaching; reception studies; didactic subject research;

   Sammanfattning : The aim of this thesis, The Historical Novel and Historical Consciousness in ten- to twelve-year-olds - Maj Bylocks Drakskeppstrilogi in Theory and Practice, is to illustrate the possibilities for pupils of the ages between ten to twelve to develop their historical consciousness by participating in classroom work making use of fiction as a central source of knowledge. In the first part of the thesis the three novels in the trilogy about the Viking age by the Swedish author Maj Bylock, Drakskeppet (1997), Det gyllne svärdet (1998) and Borgen i fjärran (1998), are analyzed.

7. 20. Numerical Techniques for Acoustic Modelling and Design of Brass Wind Instruments

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

   Sammanfattning : 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. LÄS MER
