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

    Author : Akash Patel; [2021]
    Keywords : ;

    Abstract : Mars : The red planet has been on top in the priority list of interplanetary exploration of the solar system. The Mars exploration landers and rovers have laid the foundation of our understanding of the planet atmosphere and terrain. READ MORE

  3. 7. Performance analysis of a small-scalewind turbine at variable pitch and withpitch unbalance

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Francesco Mazzeo; [2021]
    Keywords : Wind energy; wind turbine; pitch angle; pitch unbalance; Blade Element Momentum BEM theory; Computational Fluid Dynamics CFD ; wind tunnel experiments; oscillations;

    Abstract : When it comes to design a wind turbine rotor, several parameters have to be taken into account. The present work focuses on the inclination of the blades with respect to the rotor plane, namely the pich angle. READ MORE

  4. 8. Analysis and Initial Optimization of The Propeller Design for Small, Hybrid-Electric Propeller Aircraft

    University essay from KTH/Flygdynamik

    Author : Ali Alshahrani; [2020]
    Keywords : Electric; hybrid; Propeller; Optimization; variable pitch; fixed pitch; blades number; Eldrivet; hybrid; Propeller; Optimering; justerbar vinkel; fast vinkel; bladnummer;

    Abstract : This thesis focuses on the optimization of the electric aircraft propeller in order to increaseflight performance. Electric aircraft have limited energy, particularly the electricmotor torque compared to the fuel engine torque. For that, redesign of the propeller forelectric aircraft is important in order to improve the propeller efficiency. READ MORE

  5. 9. Generating Training Data for Keyword Spotting given Few Samples

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Pius Friesch; [2019]
    Keywords : ;

    Abstract : Speech recognition systems generally need a large quantity of highly variable voice and recording conditions in order to produce robust results. In the specific case of keyword spotting, where only short commands are recognized instead of large vocabularies, the resource-intensive task of data acquisition has to be repeated for each keyword individually.
