  3. 2. Design och Konstruktion av Kretskort Avsedd för Modulär Konstlast

    M1-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Calle Hellberg; [2019]
    Nyckelord :Kretskort;

    Sammanfattning : This report includes a project in which a circuit board has been designed to be used as an dummy load for pulse generators. The aim of the circuit board is to replace a resistive fabric woven from kanthal wire that ScandiNova uses as a load element at present. LÄS MER

  4. 3. Testsystem av kontrollsystem för klystronmodulatorer

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och System

    Författare :Oscar Fällman; Daniel Jönsson; [2016]
    Nyckelord :Test system; LabVIEW; TwinCAT; EtherCAT; Testsystem; LabVIEW; TwinCAT; EtherCAT;

    Sammanfattning : The company, ScandiNova Systems, has had a need for a test system that can automate and optimize fault detection of the digitizer circuit in the control system of their klystron modulators. This thesis work is intended for this need with the aim of constructing a test system built in LabVIEW, and a pulse generator to generate stimulation for the digitizer circuit board. LÄS MER

  5. 4. Effects of the carotenoid inhibiting herbicide diflufenican on the photosynthesis of benthic algae

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Jelena Rakovic; [2014]
    Nyckelord :benthic algae; freshwater; herbicides; diflufenican; PAM; fluorescence; Lake Erken; photosynthetic efficiency;

    Sammanfattning : Throughout the world, the large-scale use of pesticides in agriculture is an area of concern due to known harmful effects on human and environmental health. Mixtures of different pesticides are found in lakes and streams, where their presence endangers aquatic organisms, like benthic algae, and the ecosystem services they provide. LÄS MER

  7. 5. Investigation of the chirp properties of DFB-EAM’s for high speed baseband and RoF transmission links

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Miguel Olmedo Iglesias; [2012]
    Nyckelord :;

    Sammanfattning : The ever increasing bandwidth demands driven by an explosion in the mobile device market calls for more and more optical and wireless convergence due to the ability of optical communication systems to transport larger amounts of information to longer distances. Optical modulators are in charge of performing the electrical-to-optical domain conversion, which place them as one of the critical components in optical communication systems. LÄS MER
