  1. 11. Electric Propulsion for a High Altitude Unmanned Aerial Vehicle

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

    Author : Jacob Hjort Friderichsen; David Jönsson; [2022]
    Keywords : Electric Propulsion; UAV; ALPHA; Electronic Speed Controller; BLDC Motor; Propeller;

    Abstract : The catalogue of observational platforms for space and atmospheric research can be expanded by utilising drones equipped with specialised instrumentation and capable of flying at high altitudes. In this project the requirements for an electric propulsion system applicable to the KTH Royal Institute of Technology ALPHA project are evaluated. READ MORE

  3. 12. Numerical simulation of acoustic wave propagation with a focus on modeling sediment layers and large domains

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Elias Estensen; [2022]
    Keywords : Helmholtz; wave equation; acoustics; ocean acoustics; numerical analysis; computational science; finite differences; summation by parts; sbp; waveholtz; cylindrical coordinates; sediment layers; interface; super-grid; super grid; absorbing layer; Helmholtz; vågekvationen; akustik; undervattensakustik; numerisk analys; beräkningsvetenskap; finita differenser; summation by parts; sbp; cylindriska koordinater; waveholtz; sedimentskikt; interface; super-grid; absorberande lager;

    Abstract : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. READ MORE

  4. 13. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Treitler; [2022]
    Keywords : Fatigue; Kaplan; Hydropower; Turbine;

    Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

  5. 14. Evaluation of 3D motion capture data from a deep neural network combined with a biomechanical model

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Anna Rydén; Amanda Martinsson; [2021]
    Keywords : Human pose estimation; motion capture; deep neural network; CNN; MargiPose; biomechanical modelling; AnyBody modelling system;

    Abstract : Motion capture has in recent years grown in interest in many fields from both game industry to sport analysis. The need of reflective markers and expensive multi-camera systems limits the business since they are costly and time-consuming. READ MORE

  6. 15. Data Mapping Across Compact Cellular Tissues of Varying Morphology

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Jonas Petersson; [2021]
    Keywords : Arabidopsis thaliana; image processing; data mapping; Physics and Astronomy;

    Abstract : A problem with cellular image data from plant tissues is that it is difficult to compile and compare data from different specimens due to their varying morphology. In this thesis, a method for compiling image data from different tissues in a unified geometry is developed and evaluated on early floral buds of Arabidopsis thaliana. READ MORE
