  1. 26. Spatial domain methods for orientation and velocity estimation

    Författare :Gunnar Farnebäck; Gösta Granlund; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In this thesis, novel methods for estimation of orientation and velocity are presented. The methods are designed exclusively in the spatial domain.Two important concepts in the use of the spatial domain for signal processing is projections into subspaces, e.g. LÄS MER

  3. 27. Phase-changing flows: numerical methods and fully resolved simulations

    Författare :Nicolo Scapin; Luca Brandt; Christophe Duwig; Outi Tammisola; Matthias Ihme; KTH; []
    Nyckelord :Phase change; interface-resolved simulations; compressibility; evaporating droplets; evaporation-driven thermal convection.; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Flows with evaporation and boiling are abundant in different contexts, such as geophysics, the biomedical sectors, and industrial applications. Spray combustion, boiling bubble flows, oceanic sprays, formation and evolution of clouds, spreading of infectious diseases are all relevant examples where a deeper understanding of phase-changing flows is of great importance.

  4. 28. Developing Computational Methods for Moored Floating Wave Energy Devices

    Författare :Johannes Palm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave Power; RANS simulations; Discontinuous Galerkin; Mooring Dynamics;

    Sammanfattning : Floating point absorbers are a common class of wave-power devices typically designed to move with large amplitude in energetic waves. This stands in sharp contrast to traditional marine design, where the wave-excited motions of the structure are preferably kept to a minimum. LÄS MER

  5. 29. Fibre reinforced concrete : fracture mechanics methods applied on self-compacting concrete and energetically modified binders

    Författare :Patrik Groth; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Fibre reinforced concrete (FRC) is a type of building material that is increasing in use. As new types on concrete develops the need to update the knowledge on the use of fibre reinforcement increases. This thesis covers test methods for FRC that ranges from standard beam tests to sophisticated uniaxial tension tests. LÄS MER

  7. 30. Broadband Electromagnetic Scattering and Shielding Analysis using the Finite-Difference Time-Domain Method

    Författare :Torleif Martin; Anders Bondeson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with numerical simulations of Maxwell's equations using the Finite-Difference Time-Domain (FDTD) method. The method is widely used in scattering, antenna and electromagnetic compatibility (EMC) applications. LÄS MER
