  1. 21. Survival patterns and density-dependent processes in breeding mallards Anas platyrhynchos

    Author : Gunnar Gunnarsson; Kjell Sjöberg; Johan Elmberg; Per Lundberg; Robert Clark; Högskolan Kristianstad; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; broods; dabbling ducks; density dependence; ducklings; experiments; models; mortality; nest predation; regulation; survival; Terrestrial ecology; Terrestrisk ekologi;

    Abstract : Measuring and assessing vital rates such as births and deaths are prerequisites for understanding population dynamics. Vital rates may be affected by the density of individuals, even though the importance of density dependence on population dynamics has been debated for a long time. READ MORE

  2. 22. Estimation of risk in the field of osteoporosis

    Author : Helena Johansson; Göteborgs universitet; []
    Keywords : osteoporosis; fracture; bone mineral density; ; clinical risk factors; FRAX; Poisson model; 10 year probability; mortality; vitamin D; adiponectin;

    Abstract : Introduction: Osteoporosis has been recognised as an established and well-defined disease that affects more than 75 million people in the United States, Europe and Japan. Osteoporosis has been operationally defined by the WHO on the basis of bone mineral density (BMD) assessment. READ MORE

  3. 23. Global Pose Estimation from Aerial Images : Registration with Elevation Models

    Author : Bertil Grelsson; Michael Felsberg; Per-Erik Forssén; Kalle Åström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Over the last decade, the use of unmanned aerial vehicles (UAVs) has increased drastically. Originally, the use of these aircraft was mainly military, but today many civil applications have emerged. READ MORE

  4. 24. A Parametric Approach to Yeast Growth Curve Estimation and Standardization

    Author : Ilona Pylvänäinen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioscreen; Chapman-Richards model; growth curve; growth rate; lag time; optical density OD ; Saccharomyces cerevisiae; standardized curve; stationary phase OD increment; summary curve; optical density OD ;

    Abstract : The purpose of this thesis is to contribute to the understanding of yeast growth. It builds upon a dataset consisting of growth curves of 576 Saccharomyces cerevisiae mutants in eight different environments. The data will be a part of a publicly available phenotypic library, PROPHECY, containing growth curves and characteristics of viable S. READ MORE

  5. 25. Estimation and Model Validation of Diffusion Processes

    Author : Erik Lindström; Finansiell matematik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Estimation and Model Validation of Diffusion Processes Abstract The main motivation for this thesis is the need for estimation and model validation of diffusion processes, i.e. stochastic processes satisfying a stochastic differential equation driven by Brownian motion. READ MORE
