  2. 16. Estimation of torque in heavy duty vehicles with focus on sensor hysteresis

    Author : Marcus Hedegärd; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hysteresis modelling; adaptive hysteresis compensation; hysteresis compensation; magnetoelastic torque sensor; Preisach model; generalized Prandtl-Ishlinskii model; cylinder pressure estimation; torque estimation;

    Abstract : For diagnosis and feedback control of vehicle powertrains, it is highly desired to monitor the torques at different locations online. The most obvious way to do this is to measure cylinder pressures, from which cylinder individual delivered torques can be calculated, or to use torque sensors. READ MORE

  4. 17. 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

  5. 18. ROBUST ROTATION AND TRANSLATION ESTIMATION IN STRUCTURE FROM MOTION

    Author : Johan Fredriksson; Mathematical Imaging Group; []
    Keywords : computer vision; image analysis;

    Abstract : Due to advances in technology the amount of images from portable cameras has increased tremendously in recent years. Nowadays, most new mobile phones and cars have multiple cameras. Drones and other robots are often equipped with cameras as well. To be able to capture an image is not the same as to understand the content of it. READ MORE

  6. 19. A convex optimization approach to complexity constrained analytic interpolation with applications to ARMA estimation and robust control

    Author : Anders Blomqvist; Anders Lindquist; Giorgio Picci; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical optimization; systems theory; analytic interpolation; moment matching; Nevanlinna-Pick interpolation; spectral estimation; convex optimization; Optimeringslära; systemteori; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : Analytical interpolation theory has several applications in systems and control. In particular, solutions of low degree, or more generally of low complexity, are of special interest since they allow for synthesis of simpler systems. READ MORE

  7. 20. Towards Robust Visual Localization in Challenging Conditions

    Author : Carl Toft; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; autonomous vehicles; self-driving cars; camera pose estimation; long-term localization; Visual localization; benchmark;

    Abstract : Visual localization is a fundamental problem in computer vision, with a multitude of applications in robotics, augmented reality and structure-from-motion. The basic problem is to, based on one or more images, figure out the position and orientation of the camera which captured these images relative to some model of the environment. READ MORE
