16. Identifiability of pharmacological models from data
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : In order to automate anaesthesia in patients using propofol, closed-loop control systems with models that describe the time course of the drug effects on the body are required, usually being represented by pharmacokinetics and pharmacodynamics(PKPD). This thesis focused on evaluating parameter identifiability for the PK part of the model, using a model proposed by Eleveld et al. READ MORE

17. Efficient Sampling of Gaussian Processes under Linear Inequality Constraints
University essay from Linköpings universitet/Statistik och maskininlärningAbstract : In this thesis, newer Markov Chain Monte Carlo (MCMC) algorithms are implemented and compared in terms of their efficiency in the context of sampling from Gaussian processes under linear inequality constraints. Extending the framework of Gaussian process that uses Gibbs sampler, two MCMC algorithms, Exact Hamiltonian Monte Carlo (HMC) and Analytic Elliptical Slice Sampling (ESS), are used to sample values of truncated multivariate Gaussian distributions that are used for Gaussian process regression models with linear inequality constraints.

18. Data-driven test case design of automatic test cases using Markov chains and a Markov chain Monte Carlo method
University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)Abstract : Large and complex software that is frequently changed leads to testing challenges. It is well established that the later a fault is detected in software development, the more it costs to fix. READ MORE

19. The Milky Way and its Exoplanets
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : The detections of over 4000 exoplanets as of today has shown that they exist in a wide range of different configurations, otherwise known as architectures. Recently, studies have been made trying to link the environment of host stars to the architectures of their planetary systems and have found that the architectures of planetary systems may not necessarily be uniform in the Milky Way.

20. A Tension between the Early and Late Universe: Could Our Underdense Cosmic Neighbourhood Provide an Explanation?
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : In recent years, the increasingly precise constraints on the value of the Hubble constant, H0, have highlighted a discrepancy between the results arising from early-time and late-time measurements. A potential solution to this so-called Hubble tension is the hypothesis that we reside in a cosmic void, i.e. READ MORE
