  1. 21. Sensor implementation : Tillämpat i ett inbyggt system för att öka funktionaliteten i gruvmiljöer

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Christoffer Nilsson; [2021]
    Nyckelord :Elektronik; inbyggda system;

    Sammanfattning : This thesis was made to test an implementation of different sensor on Widefinds embedded  positioning system to increase its functionality. The underlying idea was that measurement sof physical quantities pared up with the positioning in mining operations could achieve this increase. LÄS MER

  4. 23. On the direct comparability of non-financial reports from a “Climate Action” & emissions perspective : - with specific reference to Large Cap companies on the Swedish Stock Market over a ten year period

    Magister-uppsats, Mittuniversitetet/Institutionen för ekonomi, geografi, juridik och turism

    Författare :Frances Clarke Hermansson; [2021]
    Nyckelord :Non-financial report NFR ; comparability; sustainability; framework; indicator; unit of measurement; physical quantity; CO2e; GHG emissions.;

    Sammanfattning : There are problems connected to the non-financial reports (NFRs) prepared by companies. The purpose of this study is to compare over a ten year period, the NFRs of Large Cap companies on the Swedish Stock Market, from a “Climate Action” and emissions perspective, to determine if the direct comparability of NFRs has increased within companies, if the direct comparability of NFRs between companies has increased and if regulations launched during the past decade have increased the direct comparability of NFRs.

  5. 24. Radiative Corrections Beyond the Soft-Photon Approximation

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Jacob Lindahl; [2021]
    Nyckelord :Soft-Photon Approximation; Bremsstrahlung Correction; Transition Form Factor; Radiative Corrections; Physics and Astronomy;

    Sammanfattning : This thesis calculates the bremsstrahlung correction beyond the soft-photon approximation for the decay ω → π0 l+ l- . The effect of the radiative corrections on the extraction of the transition form factor from data is investigated. LÄS MER

  7. 25. Online parameter estimation in electric motors

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Abizar Sadikot; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The permanent magnet synchronous machine (PMSM) can be used for a wide range of applications. In this case, the motor that is examined is inspired of Husqvarna's handheld electrical tools where the motor is part of its electrical chainsaw. The idea is to investigate and simulate different algorithms for online parameter estimation for the PMSM. LÄS MER
