2. 1. Robust analysis of uncertainty in scientific assessments

   Author : Ivette Raices Cruz; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; expert knowledge; robust Bayesian analysis; scientific assessments; subjective probability; uncertainty analysis;

   Abstract : Uncertainty refers to any limitation in knowledge. Identifying and characterizing uncertainty in conclusions is important to ensure transparency and avoid over or under confidence in scientific assessments. Quantitative expressions of uncertainty are less ambiguous compared to uncertainty expressed qualitatively, or not at all. READ MORE

4. 2. Bayesian Inference for Microwave Diagnostics at Joint European Torus

   Author : Stefan Schmuck; Per Brunsell; Thomas Jonsson; Jakob Svensson; Laurie Porte; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ECE; Bayesian; Fourier transform; spectroscopy; joint inference; length-scale; Gaussian process; microwave diagnostic; JET; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The major goal of this thesis is to perform Bayesian inference jointly for electron kinetic profiles, a toroidal magnetic field correction, diagnostic sensitivities, and wall reflection properties given noisy measurements of four microwave diagnostics at the tokamak JET. Besides the measurements, this kind of inference considers prior knowledge, like profile length-scales, to update objectively the information about the physics parameters. READ MORE

5. 3. Assessment of mobile radiometry data in radiological emergencies using Bayesian statistical methods

   Author : Antanas Bukartas; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mobile gamma spectrometry; Gamma spectrometry; Orphan source; lost source; Ionizing radiation; Bayesian; Activity; position; activity density; reconstruction; UAV; car-borne;

   Abstract : Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. READ MORE

6. 4. Bayesian learning of structured dynamical systems

   Author : Riccardo Sven Risuleo; Håkan Hjalmarsson; Johan Schoukens; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; bayesian learning; machine learning; Gaussian processes; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In this thesis, we propose some Bayesian approaches to the identificationof structured dynamical systems. In particular, we consider block-orientedmodels in which a complex system is built starting from simple linear andnonlinear building blocks. READ MORE

7. 5. Female sex hormones and health outcomes in women with specific focus on asthma

   Author : Guo-Qiang Zhang; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; Bayesian estimation; case-control; causal inference; estrogens; female sex hormones; hormonal contraceptives; menarche; menopausal hormone therapy; menopause; meta-analysis; multiple imputation; progestogens; research reproducibility; robust variance estimation; systematic review; umbrella review; women;

   Abstract : In humans, gender differences exist across a wide spectrum of diseases. For instance, women are more likely to develop Sjogren’s syndrome, systemic lupus erythematosus, and autoimmune thyroid disease compared to men. READ MORE
