  1. 1. Product development of hand-held scooping utensil for the pharmaceutical industry

    University essay from KTH/Ergonomi

    Author : Josefin Kruse; [2024]
    Keywords : ;

    Abstract : Musculoskeletal disorders (MSDs) are one of the most common groups of work-related illnesses. At PET Dispensing, AstraZeneca Södertälje, several MSDs had been linked to a specific scooping utensil made of stainless steel. READ MORE

  3. 2. Small scale VTOL aircraft using only one lift-producing motor : A study of lift capacity for a Vertical Take-Off and Landing capable aircraft

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Daniel Milenkovic; [2023]
    Keywords : Aircraft; VTOL; EDF; Mechatronics; Ardupilot; Luftfarkost; VTOL; EDF; Mekatronik; Ardupilot;

    Abstract : The usage of unmanned aerial vehicles in applications such as terrain mapping and surveillance is proliferating in the modern world. This project aims to investigate the feasibility, in terms of payload capacity and stability, of small scale winged aircraft that have the ability to lift and land vertically, while also being able to transition to normal forward flight using wings for primary lift.

  4. 3. Simulations of a self-stabilizing fully submerged hydrofoil

    University essay from KTH/Matematik (Avd.)

    Author : Henry Jacobson; [2023]
    Keywords : Hydrofoil; Self-Stabilizing; Lifting Line Theory; Fluid Mechanics; Numerical Methods; Backward Differentiation Formula; Fully Submerged Hydrofoil; Bärplan; bärplansbåt; självstabiliserande; lyftande linjeteori; strömningsme- kanik; numeriska metoder; Backward Differentiation Formula; fullt nedsänkt bärplan;

    Abstract : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. READ MORE

  5. 4. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  6. 5. Wind Turbine Installation Methods: Investigating Increasing Turbine Heights

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : William Anderson; [2023]
    Keywords : Installation; Construction; Large-scale; Turbine;

    Abstract : There is limited information available regarding the strategies surrounding the construction and logistical issues that will be faced in connection with the up-scaling of wind turbine technology. As wind turbines are manufactured at greater sizes, the industry will need to face these issues head-on to avoid many obstacles pertaining to transportation from the manufacturer to the project site, and the installation of massive turbine components at soaring heights.
