  1. 1. Can an investor gain positive abnormal return by mimicking insider transactions?

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Oscar Bodin; Jonatan Tell; [2021-02-24]
    Nyckelord :Nasdaq; OMX Stockholm; Insider Trading; Abnormal Return; OMXS30; Stock Market.;

    Sammanfattning : Background: The efficient market hypothesis is a theory that has been widely debated andstudied during the years. Some agree with the theory, but some disagree. One way to study theefficient market hypothesis is by looking at the possibility to gain positive abnormal return onthe stock market. LÄS MER

  2. 2. AID EFFICIENCY: CAPABILITIES ENHANCEMENT OR VALUE FOR MONEY A comparative study of Sida and DFID

    Master-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Viorica Doros; [2021-02-22]
    Nyckelord :Sen’s capability approach; value for money; aid efficiency; Sida; DFID; agency; well-being; IAGG;

    Sammanfattning : Evaluative frameworks of aid efficiency have various approaches based on donor priorities, international agreements and agenda, and existing theories in place. This thesis aims to investigate whether measurement of capabilities enhancement is losing ground to Value for Money Approach – a theory perceived to look into cost-effectiveness and economic growth only.

  3. 3. Synchrotrons as a Source for Soft X-Ray Lithography

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Thomas Joseph Grandsaert Jr; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.

  4. 4. Gate driver solutions for high power density SMPS using Silicon Carbide MOSFETs

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Farhan Akram; [2021]
    Nyckelord :SiC MOSFETs; Gate drivers; DC-DC converter; High power and efficiency power supplies;

    Sammanfattning : Discrete silicon carbide (SiC) power devices have unique characteristics that outpace those of silicon (Si) counterparts. The improved physical features have provided better faster switching, greater current densities, lower on-resistance, and temperature performances. LÄS MER

  5. 5. QRALib: A Python library for Quantitative Risk Analysis in Cybersecurity

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Sam Löthén; [2021]
    Nyckelord :;

    Sammanfattning : The risk of cyberattacks is increasing. Companies are facing more attacks and with graver consequences. To handle the risks cybersecurity practitioners use risk analysis to prioritize handling. The de-facto standard has been qualitative analysis using ordinal scales and categories. LÄS MER
