1. 16. Modeling the covariance matrix of financial asset returns

   Författare :Gustav Alfelt; Joanna Tyrcha; Taras Bodnar; Vasyl Golosnoy; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Realized covariance; Autoregressive time-series; Goodness-of-fit test; Matrix singularity; Portfolio theory; Wishart distribution; Matrix-variate gamma distribution; Parameter estimation; High-dimensional data; Moore-Penrose inverse; matematisk statistik; Mathematical Statistics;

   Sammanfattning : The covariance matrix of asset returns, which describes the fluctuation of asset prices, plays a crucial role in understanding and predicting financial markets and economic systems. In recent years, the concept of realized covariance measures has become a popular way to accurately estimate return covariance matrices using high-frequency data. LÄS MER

3. 17. Essays on Economic Modeling of Climate Change

   Författare :Gustav Engström; John Hassler; Michael Hoel; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; economic growth; energy balance models; sustainability; Economics; nationalekonomi;

   Sammanfattning : Structural change in a two-sector model of the climate and the economy introduces issues concerning substitutability among goods in a two-sector economic growth model where emissions from fossil fuels give rise to a climate externality. Substitution is modeled using a CES-production function where the intermediate inputs differ only in their technologies and the way they are affected by the climate externality. LÄS MER

4. 18. Utredningsskyldighet, bevisbörda och beviskrav i förvaltningsprocessen

   Författare :Gustav Lindkvist; Ulrik von Essen; Lars Bejstam; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; administrative procedure; burden of proof; evidentiary requirements; duty of enquiry; förvaltningsprocess; förvaltningsrätt; bevisbörda; beviskrav; utredningsskyldighet; utredningsansvar; utredningskrav; offentlig rätt; Public Law;

   Sammanfattning : This doctoral dissertation investigates the more precise meanings of the duty of enquiry, the burden of proof and the evidentiary requirements of administrative authorities and administrative courts, and the relationships between these concepts within administrative procedures. As in any procedure, different interests come to light and must be balanced. LÄS MER

5. 19. Statistical inference on interacting particle systems with applications to cancer biology

   Författare :Gustav Lindwall; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reaction-diffusion equations; bayesian inference; mathematical biology; gent based modelling; stochastic differential equations;

   Sammanfattning : Interacting particle is a mathematical framework which allows for condensed and elegant modelling of complex phenomena undergoing both deterministic and random dynamics. While there are several ways to formulate an interacting particle system, this thesis focuses on modelling such dynamics using stochastic differential equations. LÄS MER

7. 20. Computational Modeling of Macrocycles and Structure-Based Design of Novel Antibacterial Compounds

   Författare :Gustav Olanders; Anders Karlén; Peter Brandt; Christian Sköld; Dan Sindhikara; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; macrocycles; docking; conformational sampling; conformational prefer-ences; antibiotics;

   Sammanfattning : The integration of computational methods into the drug discovery process provides valuable tools to help advance new and improved drugs into the clinic. As medicinal chemists explore novel targets and new areas of chemical space, our computational toolkit must also evolve. LÄS MER
