    Sammanfattning : Denna rapport är ett resultat av utförd fallstudie på Siemens Industrial Turbomachinery AB. Studien utfördes som ett DMAIC-projekt i syfte att utvärdera befintlig processtyrning och ge förslag på nya styrparametrar för att styra och övervaka tillverkningsprocessen av rotorer. LÄS MER

  4. 3. A case study on improving energy efficiency of a Granulator in the polythene recycling machine

    Master-uppsats, KTH/Energiteknik

    Författare :Raveendra Sampath Kumara Sarukkali Kankanamge; [2018]
    Nyckelord :;

    Sammanfattning : The thesis focuses on the improvement/enhancement of energy efficiency of the machine; called Granu-lator of the recycling process of polythene. In the recycling process, it is observed that energy is wasted unnecessarily, and thus energy efficiency must be improved. The reason is that the granulator has been operating with an old rotor.

  5. 4. Braid group statistics and exchange matrices of non-abelian anyons : with representations in Clifford algebra

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Erik Sönnerlind; Gustav Brage; [2018]
    Nyckelord :;

    Sammanfattning : When leaving classical physics and entering the realm of quantum physics, there are many new concepts being introduced. One of the most fundamental ideas in quantum mechanics is that particles no longer have exact known positions, but instead expected values and prob- abilities. LÄS MER

  7. 5. Smoothing and Mapping of an Unmanned Aerial Vehicle Using Ultra-wideband Sensors

    Master-uppsats, KTH/Reglerteknik

    Författare :Erik Strömberg; [2017]
    Nyckelord :;

    Sammanfattning : Unmanned Aerial Vehicles (UAV), in particular the four-rotor quadrotor, aregaining wide popularity in research as well as in commercial and hobbyist applications.Maneuvrability, low cost, and small size make quadrotors an attractiveoption to full-scale, manned helicopters while opening up new possibilities.
