  1. 1. Developing Verification Models for Corona Discharge Suppression in High Voltage Capacitor Banks

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mohammadjavad Javadi; [2020]
    Keywords : Corona discharge; Suppression ring; High voltage capacitor banks;

    Abstract : Due to the universal considerable population and economic growth rate, demands for energy have risen significantly over the past decade. This means that the integration of renewable energies in the power grid has escalated as well as requests for reactive power compensation, voltage stability, and mitigation of harmonic filters.

  3. 2. Ganymede's hydrogen corona and FUV albedo from HST/STIS images

    University essay from KTH/Rymd- och plasmafysik

    Author : Juan Alday Parejo; [2017]
    Keywords : ;

    Abstract : Ganymedes är största månen i vårt Solsystem, och är ett föremål för intensiv vetenskaplig forskning under senaste decenier. Sedan 1998, STIS (Space Telescope Imaging Spectrograph) instrumentet ombord rymdteleskopet Hubble (HST) har observerat Ganymedes i UV ljus med våglängder mellan 1150 Å och 1730 Å i fem olika omgångar.

  4. 3. Comparison of the shock arrival times for Earth-directed ICMEs provided by the WSA-Enlil+Cone model and in-situ observations at L1: A Case Study

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Anita Linnéa Elisabeth Werner; [2016]
    Keywords : CME; ICME; CIR; WSA-Enlil Cone; CCMC; ACE; SAT; St. Patrick; Sun-Earth connection;

    Abstract : A case study which examines the agreement between prediction and data is performed for three, complex interplanetary shocks which were detected at the Sun-Earth Lagrange point L1 and induced moderate to intense geomagnetic storms. We use model output from previous runs of the coupled coronal-heliosphere WSA-Enlil+Cone model, available through the Community Coordinated Modeling Center (CCMC), and in-situ data from the OMNI data set.

  5. 4. Evaluation of surface treatment techniques for polypropylene andimplementation of a method for testing ink adhesion

    University essay from Grafisk teknik

    Author : Johanna Manngård; [2004]
    Keywords : Plast material; polypropylen; adhesion; korona; plasma; test metod.;

    Abstract : If a plastic material is used as a print bearer there are a need of a special surface treatment to get agod and durable printing. The most used surface treatment technique for the moment is coronatreatment. This kind of treatment has unfortunately showed not to be so durable in the long term. READ MORE
