  2. 11. Synergies between Policy Learning and Sampling-based Planning

    Author : Robert Gieselmann; Florian T. Pokorny; Edward Johns; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machine Learning; Robotics; Reinforcement Learning; Motion Planning; Robotic Manipulation; Datalogi; Computer Science;

    Abstract : Recent advances in artificial intelligence and machine learning have significantly impacted the field of robotics and led to the interdisciplinary study of robot learning. These developments have the potential to revolutionize the automation of tasks in various industries by reducing the reliance on human workers. READ MORE

  4. 12. Large Eddy Simulation of an Oscillating Cylinder

    Author : Andreas Feymark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical simulation; hydrodynamics; LES; subgrid modeling; forced oscillation;

    Abstract : In this thesis Large Eddy Simulation of an Oscillating Cylinder is carried out studying the governing flow physics and modeling aspects such as effect of grid resolution and subgrid model. This also involves validation of the predictions with experimental data in terms of Fourier analysis, magnitude and characteristic shape of drag and lift force profiles. READ MORE

  5. 13. Methods of Multi-Conjugate Adaptive Optics for Astronomy

    Author : Ralf Flicker; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adaptive optics; anisoplanatism; laser guide stars; performance estimation; wavefront reconstruction; extremely large telescopes; optics; Electromagnetism; Elektromagnetism; acoustics; Astronomy; akustik; space research; optik; multi-conjugate; cosmic chemistry; Astronomi; rymdvetenskap; kosmisk kemi; Fysicumarkivet A:2003:Flicker;

    Abstract : This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future.

  6. 14. Algorithms for magnetic resonance imaging in radiotherapy

    Author : Jens Sjölund; Hans Knutsson; Anders Eklund; Mats Andersson; Evren Özarslan; Aasa Feragen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Radiotherapy plays an increasingly important role in cancer treatment, and medical imaging plays an increasingly important role in radiotherapy. Magnetic resonance imaging (MRI) is poised to be a major component in the development towards more effective radiotherapy treatments with fewer side effects. READ MORE

  7. 15. Methods for Reliable Image Registration : Algorithms, Distance Measures, and Representations

    Author : Johan Öfverstedt; Natasa Sladoje; Mattias Heinrich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image registration; alignment; local optimization; global optimization; mutual information; normalized gradient fields; representation learning; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Much biomedical and medical research relies on the collection of ever-larger amounts of image data (both 2D images and 3D volumes, as well as time-series) and increasingly from multiple sources. Image registration, the process of finding correspondences between images based on the affinity of features of interest, is often required as a vital step towards the final analysis, which may consist of a comparison of images, measurement of movement, or fusion of complementary information.
