  1. 21. A parametric study of oil-jet lubrication in gear wheels

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Dona Biju; [2018]
    Nyckelord :Jet lubrication; velocity ratio; inlet size; heat transfer;

    Sammanfattning : A parametric study of oil-jet lubrication in gear wheels is conducted using Computational Fluid Dynamics (CFD) to study the effect of the different design parameters on the cooling performance in a gearbox. Flow in oil jet lubrication is found to be complex with the formation of oil ligaments and droplets. Various hole radii of 1.5, 2 and 2. LÄS MER

  3. 22. Adopting DevOps in Agile: Challenges and Solutions

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :Cheng Wang; Changling Liu; [2018]
    Nyckelord :DevOps; Agile; Development Process; Systematic Literature Review;

    Sammanfattning : Background. DevOps is a hot topic in recent years. It emphasizes the combination of development and operation. Agile is one of the most popular development methods, but Agile mainly focused on software development part, there is no more involvement in deployment and operations. LÄS MER

  4. 23. Tillskott av hydrauleffekt från traktorns kraftuttagsaxel : Konceptstudie av externa pumpar för såmaskiner

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

  5. 24. An empirical study of Agile planning critical success factors

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Författare :Di Liu; Zhichao Zhai; [2017]
    Nyckelord :Agile software development; critical success factors; Agile planning phase;

    Sammanfattning : Context. With the popularity of Agile methods, many studies about Agile software development has been done by researchers. Among the phases in Agile software projects, planning is critical because it provides an overview of the project and a guiding of future work. LÄS MER

  7. 25. A Noncommutative Catenoid

    Kandidat-uppsats, Linköpings universitet/Matematik och tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Christoffer Holm; [2017]
    Nyckelord :noncommutative; catenoid; noncommutative geometry; diamond lemma; noncommutative algebra; ore condition;

    Sammanfattning : Noncommutative geometry generalizes many geometric results from such fields as differential geometry and algebraic geometry to a context where commutativity cannot be assumed. Unfortunately there are few concrete non-trivial examples of noncommutative objects. LÄS MER
