  1. 21. Check! Projektmedarbetares behov av progress och struktur : En kvalitativ studie av Work Flow-metoden

    Magister-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Maria Wikström; [2019]
    Nyckelord :Structure; progress; Project management; motivation; Pomodoro-method; Work Flow; Struktur; progress; projektledning; motivation; Pomodoro-metoden; Work Flow;

    Sammanfattning : Studiens syfte är att undersöka om det strukturella stöd som Work Flow (ett event baserat på Pomodorometoden) erbjuder upplevs vara till nytta i en projektmedarbetares vardag. En kvalitativ undersökning belyser varför sju projektmedarbetare söker denna struktur i sin arbetsdag och vilken nytta erfarenheterna upplevs ge. LÄS MER

  3. 22. Avrinningskoefficienten – dess relation till regnintensitet och bidragskoefficienten utifrån fallstudier i södra Sverige

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Therese Grönvall; Linnea Ek; [2018]
    Nyckelord :avrinningskoefficient; bidragskoefficient; ytavrinning; regnintensitet; water engineering; environmental engineering; avloppsteknik; vatten försörjningsteknik; Technology and Engineering;

    Sammanfattning : In order to increase the knowledge regarding how the runoff coefficient varies with increased rainfall intensity, a literature study and calculations in Excel were conducted. The background to how the tabled values of the runoff coefficient have been determined was found to be a book based on an assembly of answers to a survey collected from different companies in USA.

  4. 23. Model-based Study of Mixing- using Computational Fluid Dynamics and Experiments

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Victor Åberg; Ameer Shareef; [2018]
    Nyckelord :Fluid dynamics; Chemical engineering; Kemiteknik; Technology and Engineering;

    Sammanfattning : Mixing in millimeter scale applications faces completely different challenges compared with the macro scale. A thorough understanding of the physics and mass conservation principles that are affecting the fluid dynamics, are therefore key for development and successful implementation of mixers, in an existing process.

  5. 24. Design of a Dynamic Boom Suspension System in a Hybrid Wheel Loader

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Ayoub Ayoub; Carl Martin Berg; [2018]
    Nyckelord :Wheel loaders; passive damming; active damping; dynamic damping; PID controllers; vibrations; hydraulics.;

    Sammanfattning : Wheel loaders are under the influence of low frequency vibrations that may be harmful for the health of the operator, and for the productivity of the machine. The strong vibrations can significantly impact the operation of the machine since they are not equipped with wheel suspension systems and due to their work environment in rough terrains with uneven surfaces.

  7. 25. Modeling Dielectric Barrier Discharge plasma actuators to be used for active flow control

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Oscar Eriksson; [2018]
    Nyckelord :Dielectric Barrier Discharge; plasma; flow control;

    Sammanfattning : This Master Thesis work cover the simulation of the movement of charged species exposed to a high gradient electric field, the same environment a plasma actuator produces. The final goal is to use the plasma actuator as an active flow control device to decrease the drag of a body moving in air. LÄS MER
