  1. 1. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Alex Eriksson; [2023]
    Keywords : Concrete; numerical analysis; trough bridge; railway bridge; finite element model; discrete element method; Betong; numeriskanalys; trågbro; tågbro; finita elementmetoden; diskreta elementmetoden;

    Abstract : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.

  3. 2. Modulation of the optical properties of quantum dots by surface acoustic waves

    University essay from KTH/Tillämpad fysik

    Author : Tanguy Schetelat; [2023]
    Keywords : Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

    Abstract : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. READ MORE

  4. 3. Berättelser från ett kulturlandskap : ett gestaltningsförslag för Nikkaluokta turistanläggnings utemiljö

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Alexander Morell; [2022]
    Keywords : Landskapsnarrativ; fjällen; kulturlandskap; Sápmi; samisk arkitektur;

    Abstract : Samernas traditionella marker, Sápmi, har en lång historia av kolonialism och förtryck. I bygget av den svenska nationella identitet har fjällen ofta porträtterats som en orörd natur, vars storslagenhet symboliserade nationens storhet. READ MORE

  5. 4. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

    University essay from KTH/Energiteknik

    Author : Max Hesselbrandt; [2021]
    Keywords : ;

    Abstract : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

  6. 5. Slab and Powder-Snow avalanche animation on the GPU

    University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

    Author : Åleskog Jonthan; Cheh Daniel; [2021]
    Keywords : Avalanche; GPU; DEM; Real-time; Games; Lavin; GPU; DEM; Realtid; Spel;

    Abstract : Background: The video game industry has yet to achieve a physically-based real-time avalanche simulation because of the sheer complexity of modeling the behavior of snow avalanches. An avalanche is made out of snow, meaning it would require a snow simulation which itself already shows to be complex. READ MORE
