  1. 21. Numerical methods for wave propagation in solids containing faults and fluid-filled fractures

    Författare :Ossian O'Reilly; Jan Nordström; Per Lötstedt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis develops numerical methods for the simulation of wave propagation in solids containing faults and fluid-filled fractures. These techniques have applications in earthquake hazard analysis, seismic imaging of reservoirs, and volcano seismology. A central component of this work is the coupling of mechanical systems.

  3. 22. Modeling and Characterization of nonlinear Materials for Protection of Optical Sensors

    Författare :Anders Eriksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns nonlinear materials and experimental techniques for optical power limiting applications. Theoretical models to analyze and simulate related measurements were studied. Two different numerical modeling tools for propagation of optical radiation through optically nonlinear media were developed. LÄS MER

  4. 23. Mechanisms of Tissue Vascularization

    Författare :Witold Kilarski; Pär Gerwins; Lena Claesson-Welsh; Andreas Bikfalvi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; vascularization; angiogenesis; granulation tissue; myofibroblast; wound healing; Patologi; Pathology; Patologi;

    Sammanfattning : Tissue neovascularization in postnatal life occurs during post-traumatic tissue healing, neoplastic growth and in the endometrium during the reproductive cycle of females. Although embryonic angiogenesis has been intensively studied, far less is known about tissue revascularization and vessel remodeling in adults due to methodological difficulties. LÄS MER

  5. 24. Physical and numerical modelling of flow pattern and combustion process in pulverized fuel fired boiler

  7. 25. Applications in Monocular Computer Vision using Geometry and Learning : Map Merging, 3D Reconstruction and Detection of Geometric Primitives

    Författare :David Gillsjö; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scene Completion; Deep Learning; Bayesian Neural Network; Room Layout Estimation; Line Segment Detection; Polygon Detection; Graph Neural Network; Map Merging; Structure from Motion; Minimal Solvers; Wireframe Estimation;

    Sammanfattning : As the dream of autonomous vehicles moving around in our world comes closer, the problem of robust localization and mapping is essential to solve. In this inherently structured and geometric problem we also want the agents to learn from experience in a data driven fashion. LÄS MER
