  1. 1. Analogue Circuit for Detection of Ageing Phenomena in Electric Drives

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yudong Lin; [2023]
    Nyckelord :Electric Drives; Ageing Process; Pulse-Width Modulation; Ringing Current; Peak Holder; Analogue Circuits; Elektriska drivsystem; Åldringsprocess; Pulsbreddsmodulering; Ringningar i strömmen; Toppvärdesdetektor; Analog krets;

    Sammanfattning : This master thesis presents an analogue peak holder circuit design aimed at facilitating the non-invasive inspection of the ageing process in electric drives. The ageing process of electric drives is a crucial aspect that demands accurate monitoring to ensure their long-term performance and reliability. LÄS MER

  3. 2. Phase Noise Performance of a PLL Frequency Synthesizer when Powered by Silent Switchers

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sampriti Basu; [2023]
    Nyckelord :Silent Switcher; PLL synthesizer; Phase noise; PCB implementation.; Silent Switcher; PLL-synthesizer; fasbrus; PCB-implementering.;

    Sammanfattning : In use today are ‘normal’ DC-DC switching regulators with considerable switching noise and ringing, which is bad for noise-sensitive applications. This project involves a solution based on ‘Silent Switchers’ to prove its effectiveness in reducing noise. LÄS MER

  4. 3. Sparvugglans (Glaucidium passerinum) invasioner vid Hammarö Fågelstation, Värmland

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Amanda Odénius Hedman; [2023]
    Nyckelord :invasion; irruptions; irruptive migration; ecology; behavior; bird migration; eurasian pygmy own; glaucidium passerinum; Invasion; migration; beteende; ekologi; fågelmigration; sparvuggla; glaucidium passerinum; migrationsmönster;

    Sammanfattning : Sparvugglan (Glaucidium passerinum) är en invasionsfågel som uppvisar årliga fluktuationer i sina invasioner vid Hammarö Fågelstation. Invasioner av denna art utlöses vanligtvis av brist på föda tidigt under hösten, vilket kan orsaka att hundratals fåglar migrerar på ett oförutsägbart sätt. LÄS MER

  5. 4. Input shaping in a cantilever 3D printer : Construction and evaluation

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Albert Achrén; Jacob Bårdén; [2023]
    Nyckelord :FDM; 3D printing; input shaping; cantilever; additive manufacturing; FDM; 3D Printing; inout shaping; fribärande; additiv tillverkning;

    Sammanfattning : FDM 3D printing is an additive manufacturing technology that is widely used, mainly for rapid prototyping. It is also one of the cheapest and most accessible AM technologies for consumers. FDM printers, and especially cheaper alternatives, can have problems with creating high quality prints. LÄS MER
