  1. 16. Multivariate Aspects of Phylogenetic Comparative Methods

    Author : Krzysztof Bartoszek; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; General Linear Model; Ornstein-Uhlenbeck process; Multivariate phylogenetic comparative method; Evolutionary model; Adaptation; Optimality; Measurement error; Regression; Adaptation; Major-axis regression; Reduced major-axis regression; Structural equation; Allometry; Phylogenetic inertia; Allometry;

    Abstract : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. READ MORE

  2. 17. Optimal Control and Model Reduction of Nonlinear DAE Models

    Author : Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAE Models; Optimal Control; Model Reduction; Automatic control; Reglerteknik;

    Abstract : In this thesis, different topics for models that consist of both differential and algebraic equations are studied. The interest in such models, denoted DAE models, have increased substantially during the last years. READ MORE

  3. 18. An animal model of sport related concussive brain injury

    Author : Hayde Bolouri; Göteborgs universitet; []
    Keywords : animal model; football; concussion; brain injury; neuropathology; cognitive function;

    Abstract : A new animal model for concussion of the type seen in professional football was developed, since current animal models did not simulate these conditions. The model is characterized by a high velocity-low mass impact to the head of a freely moving object. Structural damages and functional effects of the model have been investigated. READ MORE

  4. 19. Development and validation of a localized murine candidiasis model : The pathogenesis, chemotheraphy and defense mechanisms to Candida mastitis in the lactating mouse

    Author : Faisal Abdi Guhad; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Murine model; Candida albicans; Pathogenesis; Virulence factors; Amphotericin B; Fluconazole; Complement activation; C3c; SCID mice; Nude mice; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : A murine model of localized candidiasis (mastitis) was developed. The model was analyzed withrespect to its discriminative abilities through investigation of the virulence properties of C.albicans mutant strains compared with the wild-type parental strain. READ MORE

  5. 20. Modeling and Model Reduction by Analytic Interpolation and Optimization

    Author : Giovanna Fanizza; Anders Lindquist; György Michaletzky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytic Interpolation theory with a degree constraint; rational covariance extension problem; spectral estimation; model reduction; optimization; passive system; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : This thesis consists of six papers. The main topic of all these papers is modeling a class of linear time-invariant systems. The system class is parameterized in the context of interpolation theory with a degree constraint. READ MORE
