  1. 1. Dynamics of a CRAFT : A simulation study on a Counter Rotating vertical Axis Floating Tilting wind turbine

    University essay from Uppsala universitet/Elektricitetslära

    Author : Benjamin Hedlund Peters; Linda Goude; [2023]
    Keywords : wind power; counter rotating; contra rotating; offshore wind; floating wind power; vertical axis wind turbine; VAWT; renewable energy;

    Abstract : In this thesis the Counter Rotating vertical Axis Floating Tilting wind turbine (CRAFT) has been explored by creating a simulation model in the program Simulink. The CRAFT prototype is a new type of wind turbine under development by World Wide Wind and Uppsala University with the aim to produce a large scale floating vertical axis wind turbine (VAWT) with two cone shaped counter rotating turbines.

  3. 2. Flame Extensions Under Ceilings

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Martin Sturdy; [2023]
    Keywords : Flame length; curved ceiling; Technology and Engineering;

    Abstract : In this Master thesis project the factors affecting flame extension under flat and curved ceilings have been investigated. An experimental campaign was carried out in Lund University’s Fire Lab using a propane gas burner and heptane pool fire in different positions and heat release rates within the setups. READ MORE

  4. 3. Swedish Language End-to-End Automatic Speech Recognition for Media Monitoring using Deep Learning

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Hector Nyblom; [2022]
    Keywords : Automatic Speech Recognition; Deep Learning; Machine Learning; Natural Language Processing; Media Monitoring;

    Abstract : In order to extract relevant information from speech recordings, the general approach is to first convert the audio into transcribed text. The text can then be analysed using well researched methods. NewsMachine AB provides customers with an overview of how they are represented in media by analysing articles in text form. READ MORE

  5. 4. Dynamics of streamflow and stream chemistry in a Swiss pre-Alpine headwater catchment : A fine scale investigation of flow occurrence and electrical conductivity in the temporary streams in the lower Studibach catchment

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Elise Baumann; Hanna Berglund; [2021]
    Keywords : Temporary Streams; Pre-Alpine Catchment; Streamflow; Stream Chemistry; Fine Scale Investigation; Electrical-conductivity; Stream Mapping; Temporära bäckar; Pre-Alpina avrinningsområden; Bäckflöden; Vattenkemi; Finskalig undersökning; Elektrisk konduktivitet; Bäck-kartering;

    Abstract : Temporary streams and their dynamics have often been largely overseen in hydrological research and there is relatively little knowledge about how the occurrence of flow in these streams varies temporally and spatially. Temporary streams are important from a hydro- logical perspective because they affect water quantity and quality in downstream peren- nial reaches, and from an ecological perspective because they provide habitat to unique species.

  6. 5. Topology optimization with optimal spatially varying length scale

    University essay from Lunds universitet/Innovation

    Author : Stefan Lopar; [2020]
    Keywords : Topology optimization; Varying length scale; Technology and Engineering;

    Abstract : Density based topology optimization has become an efficient way to design optimal complex structures with different goals, constraints and boundary conditions. To regularize the solution, density filters are utilized and is controlled by the length scale. READ MORE
