  2. 11. Regressor and Structure Selection : Uses of ANOVA in System Identification

    Author : Ingela Lind; Lennart Ljung; Torsten Söderström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Regressor selection; Analysis of variance; Nonlinear systems; Structure selection; Automatic control; Reglerteknik;

    Abstract : Identification of nonlinear dynamical models of a black box nature involves both structure decisions (i.e., which regressors to use and the selection of a regressor function), and the estimation of the parameters involved. READ MORE

  4. 12. Genetic structure and dispersal in plant populations

    Author : Johan Fogelqvist; Martin Lascoux; Sophie Gerber; Beng-Olle Bengtsson; Uppsala universitet; []
    Keywords : population genetics; dispersal; structure; plant; gene flow;

    Abstract : This thesis focuses on the spatial structure and methods to identify spatial structure in plants. Methods that investigate genetic structure can mainly be divided into equilibrium methods that reveal summed dispersal over many generations, and cluster methods, that reveal more recent dispersal events.

  5. 13. Local magnetic susceptometry : Visualizing functional properties of novel materials

    Author : Ziyan Gu; K. V. Rao; Robert D. Shull; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : One of the rapidly growing instrumentation technologies of late has been Surface Probe Microscopy. Since the award of the Nobel Prize in 1986, this form of instrumentation has expanded into various fascinating forms and is successfully enabling investigations at a nano-scale. READ MORE

  6. 14. Local Structure of Hydrogen-Bonded Liquids

    Author : Matteo Cavalleri; Lars G.M. Pettersson; John Tse; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen-bond; water; ice; density functional theory; DFT; core-level spectroscopies; x-ray absorption; Physical chemistry; Fysikalisk kemi;

    Abstract : Ordinary yet unique, water is the substance on which life is based. Water seems, at first sight, to be a very simple molecule, consisting of two hydrogen atoms attached to one oxygen. READ MORE

  7. 15. X-ray Absorption Spectroscopy on Nano-Magnet Arrays and Thin Films : Magnetism and Structure

    Author : Andreas Persson; Dimitri Arvanitis; Cormac McGuinness; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self organization; nano-magnet; xmcd; exafs; peem; magnetism; Surfaces and interfaces; Ytor och mellanytor; Magnetism; Magnetism; Materiefysik; Physics of Matter;

    Abstract : The magnetic and structural properties of nano magnet arrays and ferromagnetic thin films are investigated. Circular x-rays are used and extensive use is made in this Thesis of the X-ray Magnetic Circular Dichroism (XMCD) technique. By means of the XMCD magneto-optic sum rules the values of the orbital and spin moments are determined. READ MORE
