  1. 1. THE SHIFT TOWARD ELECTRIFICATION IN THE AUTOMOTIVE INDUSTRY - A Scenario Analysis Investigating What Sourcing Mode for Lithium-Ion Battery Cells Original Equipment Manufacturers Can Take to Meet Future Demand in The United States

    University essay from Göteborgs universitet/Graduate School

    Author : Nicolina Jacobsson; Sara Svärd; [2020-07-22]
    Keywords : Automotive Industry; Electrification; Electrification in the United States; Lithium-ion Battery Cells; Scenario Planning; Sourcing; Sourcing Continuum; Transaction Cost Theory;

    Abstract : The automotive industry is one of the main contributors to greenhouse gas emissions and hasconsequently commenced its transition toward producing more sustainable vehicles. Electric vehiclesare contributing to sustainable development and due to new components, original equipmentmanufacturers are facing substantial supply chain challenges. READ MORE

  3. 2. Plasma density characteristics of magnetic holes near the Kronian magnetosphere boundary surfaces

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Marlon Luis Bause; [2020]
    Keywords : Magnetic holes; Saturn; Langmuir Probe; plasma electron density; Magnetosphere;

    Abstract : Localized structures of the magnetic field strength depression are often observed in the interplanetarymedium, and they are called ‘magnetic holes’ after the original work of Turner et al. 1977. A numberof observations of similar features have been reported, while the mechanisms of their origin have notfully understood yet. READ MORE

  4. 3. Vibrational prediction of a waste water pump

    University essay from KTH/Hållfasthetslära

    Author : Daniel Sundström; [2020]
    Keywords : ;

    Abstract : An off-market waste water pump is suspected to have high vibrational velocity levels. These vibrations are sought after at the outer surface located at the upper bearing position of the pump. It has then become of interest for trying to predict these vibrations by using the commercial FEA software COMSOL. READ MORE

  5. 4. Response of Footbridges equipped with TLD : A numerical and experimental assessment

    University essay from KTH/Bro- och stålbyggnad

    Author : Silhady Tshitende Luboya; [2020]
    Keywords : Tuned liquid damper; tuned mass damper; dynamic analysis; dynamics evaluation; vibration; footbridge; human-induced vibrations; parametric study; serviceability; assessment.;

    Abstract : In recent years, an increase to design slender and aesthetically-pleasing structures have resulted in some structures having a low natural frequency. This is because the design calculation did not meet the requirement of serviceability performance. READ MORE

  6. 5. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Markus Hansell; Panagiotis Tamtakos; [2020]
    Keywords : Hollow core slab; Structural dynamics; Signal analysis; Mode shape; Frequency response function; Complex mode; FE-model; Håldäcksbjälklag; Strukturdynamik; Signalanalys; Modform; Frekvenssvar; Komplex mod; FE-modellering.;

    Abstract : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. READ MORE
