  2. 1. Dynamics of Biomembranes and Rheological Properties of Living Cells

    Author : Peter Berntsen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell mechanics; lipid dynamics; cell rheology; biomembranes; water dynamics; relaxations; phospholipids; glass transition;

    Abstract : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. READ MORE

  4. 2. Computational Methods for Computer Vision : Minimal Solvers and Convex Relaxations

    Author : Viktor Larsson; Mathematical Imaging Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Geometric Vision; minimal solvers; Convex relaxation; Pose estimation;

    Abstract : Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. READ MORE

  5. 3. Robust Estimation of Motion Parameters and Scene Geometry : Minimal Solvers and Convexification of Regularisers for Low-Rank Approximation

    Author : Marcus Valtonen Örnhag; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Visual Odometry; Simultaneous Localization and Mapping; minimal solvers; Convex relaxations; Structure from motion;

    Abstract : In the dawning age of autonomous driving, accurate and robust tracking of vehicles is a quintessential part. This is inextricably linked with the problem of Simultaneous Localisation and Mapping (SLAM), in which one tries to determine the position of a vehicle relative to its surroundings without prior knowledge of them.

  7. 5. Marginal Productivity Indices and Linear Programming Relaxations for Dynamic Resource Allocation in Queueing Systems

    Author : Jianhua Cao; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Markov decision process; Indexability; Linear programming; Queueing theory; Optimization;

    Abstract : Many problems concerning resource management in modern communication systems can be simplified to queueing models under Markovian assumptions. The computation of the optimal policy is however often hindered by the curse of dimensionality especially for models that support multiple traffic or job classes. READ MORE
