    Sammanfattning : Dynestadsjön in Gamleby, Västervik municipality, has a history of collapses due to lack ofoxygen and high levels of salt, nitrogen and phosphorus. The high levels of nutrients havegiven rise to deteriorating living conditions for aquatic organisms. LÄS MER

  2. 2. ADDITIVE MANUFACTURING FOR ASSISTIVE TECHNOLOGY : Innovative Design for an Ankle Foot Orthosis

    Master-uppsats, Jönköping University/JTH, Industridesign

    Författare :Theresa Hoai-Thuong Nguyen; [2021]
    Nyckelord :Ankle Foot Orthosis; Orthotics; Assistive Technology; 3D Printing; 3D Scanning; Additive Manufacturing; Self-Expression; Personalization; Customization; Human Rights;

    Sammanfattning : The following report presents a Master thesis project about a re-design of an ankle foot orthosis using additive manufacturing as the production method, conducted by a student in Spring 2020 as part of the Master’s programme Industrial Design at Jönköping University’s School of Engineering. Ankle foot orthoses are the most prescribed lower extremity orthoses worldwide and are worn in a visually obtrusive way making patients feel stigmatized for their disability. LÄS MER

    Sammanfattning : Most companies that have any type of combustion or other pollution process via emission to air needs to measure their emissions to ensure they are within legal boundaries. Among the different types of pollution measurements, one of the most common is dust concentration, also known as particle concentration. LÄS MER

  5. 5. A Digital Test Bench for Pneumatic Brakes

    Master-uppsats, KTH/Spårfordon

    Författare :Bastian Schick; [2021]
    Nyckelord :Compressed air brake; Freight train; Modular simulation; Pneumatics; Railways; System modelling; Tryckluftsbroms; Godståg; Modulär Simulering; Pneumatik; Järnväg; Systemmodellering;

    Sammanfattning : This master’s thesis covers the structuring and implementation of a digital testbench for the air brake system of freight trains. The test bench will serveto further improve the existing brake models at Transrail Sweden AB. Theseare used for the optimised calculation of train speed profiles by the DriverAdvisory System CATO.
