2. A new high-order method for direct numerical simulations of turbulent wall-bounded flows
Sammanfattning : A new method to perform direct numerical simulations of wall-bounded flows has been developed and implemented. The method uses high-order compact finite differences in wall-normal (for channel flow) or radial direction (for pipe flow) on a collocated grid, which gives high-accuracy results without the effectfof filtering caused by frequent interpolation as required on a staggered grid.

3. Enhancing Direct Searches for Dark Matter : Spatial-Temporal Modeling and Explicit Likelihoods
Sammanfattning : Astronomical and cosmological observations on different scales point to the existence of dark matter. In the current cosmological paradigm this dark matter accounts for about 26% of the energy-density of the universe, yet has not been directly observed. LÄS MER
4. Development and testing af an observation-based method to assess person-centeredness in healthcare
Sammanfattning : Person-centred care (PCC) has been designated and endorsed as a core competency needed for health care professionals (HCP) to meet the evolving challenges facing health care. The aim of this thesis was to develop and test an observation-based method for assessing clinician competency in the delivery of PCC. LÄS MER
5. Fatigue Assessment of Container Ships – a Contribution to Direct Calculation Procedures
Sammanfattning : Within the field of marine structural engineering, the introduction of new materials and material classes, the development of production techniques and new design, and new requirements imposed by authorities are examples which justify a need for continuous revisit and update of fatigue assessment methodologies of marine structures. This thesis contributes to the development and improvement of fatigue assessment methodology for ship structures. LÄS MER
