    Keywords : Embankment dams; reliability-based analysis; slope stability analysis; internal erosion; dam safety; fyllningsdammar; tillförlitlighetsbaserad analys; analys av släntstabilitet; inre erosion; dammsäkerhet;

    Abstract : Embankment dams are widely used as water-retaining structures through the world. Two principal structural failure modes of embankment dams are internal erosion and slope instability. The objective of this thesis is to investigate the feasibility of applying probabilistic methods in embankment dam assessment. READ MORE

  3. 12. Evaluation of the wavefronts and spatial structures of ultrashort pulses passing through a micro-channel plate

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Simon Ek; [2019]
    Keywords : high-order harmonic generation; HHG; micro-channel plate; MCP; attophysics; Physics and Astronomy;

    Abstract : The first aim of this project is to make high-order harmonic (HHG) setups more compact and user-friendly, by including a micro-channel plate (MCP). Simulations of the transmission properties of an MCP has been performed. These simulations displayed introduced structure in the far field, but a very well behaved beam in the near field. READ MORE

  4. 13. A case study of runoff coefficients for urban areas with different drainage systems

  6. 15. A comparative study of preparation methods used for bee heads prior to microCT imaging as well comparing eye to head ratio in five different bee species

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Per Alftrén; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : The complexity and importance of the eyes of a rather simple organism, the bee, is apparent when looking at the adaptation to their environment. The so called compound eyes consists of multiple facets, each having their own point of view and combined results in a larger image. READ MORE
