  2. 21. Sensor Fusion and Control Applied to Industrial Manipulators

    Author : Patrik Axelsson; Mikael Norrlöf; Fredrik Gustafsson; Paolo Rocco; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Robots; Sensor Fusion; Iterative Learning Control; H-infinity Controller; Controllability; Extended Kalman Filter; Particle Filter; Expectation Maximisation; Continuous-time Filtering; Norm-optimal ILC;

    Abstract : One of the main tasks for an industrial robot is to move the end-effector in a predefined path with a specified velocity and acceleration. Different applications have different requirements of the performance. READ MORE

  4. 22. 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. 23. Sources, transport and fate of perfluoroalkyl acids in the atmosphere

    Author : Jana Johansson; Ian Cousins; Tom Harner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfluorinated alkyl acids; PFOS; PFOA; Isomers; Sources; Atmospheric transport; Sea spray; Gas-particle partitioning; Volatilisation; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Perfluoroalkyl acids (PFAAs) are man-made chemicals which have been observed in the global environment, even in locations far away from where they are emitted. These persistent substances are taken up in humans and biota and may have toxic effects. READ MORE

  6. 24. Image Filtering Methods for Biomedical Applications

    Author : M. Khalid Khan Niazi; Ewert Bengtsson; Ingela Nyström; Lucas J. van Vliet; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital image analysis; Image filtering; Intensity inhomogeneity correction; Empirical mode decomposition; Particle Swarm optimization; Image registration; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Filtering is a key step in digital image processing and analysis. It is mainly used for amplification or attenuation of some frequencies depending on the nature of the application. Filtering can either be performed in the spatial domain or in a transformed domain. READ MORE

  7. 25. Development and Evaluation of a Denuder-Filter System Designed for Sampling Diisocyanate Aerosols

    Author : Yvonne Nordqvist; Ulrika Nilsson; Peter Haglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cylindrical denuder; Diisocyanate; TDI; HDI; IPDI; MDI; Chemosorption; Vapour particle distribution; Aerosol sampling; Analytical chemistry; Analytisk kemi;

    Abstract : There are many occupational environments in which isocyanates or PUR-products are used, produced or processed. During these operations there is always a risk of isocyanate exposure, which may lead to severe health problems. Isocyanates principally affect the respiratory system and they are the main cause of occupational asthma. READ MORE
