  2. 1. Simulation-based Inference : From Approximate Bayesian Computation and Particle Methods to Neural Density Estimation

    Author : Samuel Wiqvist; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bayesian statistics; computational statistics; deep learning; mixed­-effects; sequential Monte Carlo; stochastic dif­ferential equations;

    Abstract : This doctoral thesis in computational statistics utilizes both Monte Carlo methods(approximate Bayesian computation and sequential Monte Carlo) and machine­-learning methods (deep learning and normalizing flows) to develop novel algorithms for infer­ence in implicit Bayesian models. Implicit models are those for which calculating the likelihood function is very challenging (and often impossible), but model simulation is feasible. READ MORE

  5. 3. Urban-Based Agriculture and Poultry Production : The Case of Kisumu and Thika in Kenya

    Author : Samuel Omondi; Institutionen för kulturgeografi och ekonomisk geografi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban agriculture; urban-based rural agriculture; poultry production; poultry value chain; food security; Kenya;

    Abstract : Kenya’s population is rapidly growing and urbanising. Poverty and problems of food insecurity are equally urbanising at an unprecedented rate. Formal employment has not kept pace with the job demand of the growing population. READ MORE

  6. 4. Entomological Lidar : Target Characterization and Field Applications

    Author : Samuel Jansson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lidar; Laser radar; Scheimpflug lidar; Entomological lidar;

    Abstract : This thesis treats entomological lidar from various angles: laboratory reference work on insects of interest, methodological development of lidar- and data processing methods, as well as field implementations of lidar techniques for entomological research. Insects are crucial components of ecosystems and are currently in a global decline. READ MORE

  7. 5. Physiology and Pathophysiology of Hormone Secretion from lslets of Langerhans

    Author : Samuel Acreman; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet; diabetes; glucagon; insulin; somatostatin; incretin; pancreas; hypoglycaemia; tetraspanin; GLP-1; endoplasmic reticulum;

    Abstract : Diabetes is a metabolic disorder stemming from the improper regulation of blood glucose levels by hormones secreted by pancreatic islets of Langerhans. Paper I describes the mechanism by which glucose can regulate glucagon secretion, independent of membrane potential, from pancreatic α-cells, via modulation of endoplasmic reticulum Ca2+ handling.
