  1. 1. ABB Chasing Higher Margins - Focuses on Core Business

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Lovisa Berglund; Filip Fröjd; [2023]
    Nyckelord :Mergers and Acquisitions; Divestment; Conglomerate;

    Sammanfattning : In this paper the divestment of a business unit made by the Swedish-Swiss company ABB to the Japanese company Hitachi will be studied. The paper follows a case study methodology and aims to answer why ABB made this divestment as well as if the transaction was successful and at a fair price. LÄS MER

  3. 2. Optimering av spillvattenflöden

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Filip Berglund; [2022]
    Nyckelord :Optimization; Wastewater network; Optimal control; Pumping system; Optimering; Spillvattennätverk; Optimal styrning; Pumpsystem;

    Sammanfattning : This thesis aims to produce a control strategy that minimizes the energy usage of the pumps in the sewer system of Växjö City. The pumps are located in a small number of pumping stations. These are connected by a network of pipes in a way that requires the control of the pumps to be coordinated, both within and between the pumping stations. LÄS MER

  4. 3. Momentum in Financial Crises: An Evaluation of the Momentum Investing Strategy During Different Time Periods

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Lovisa Berglund; Filip Fröjd; [2021]
    Nyckelord :Big Data; Momentum; Finance; Financial Crises; Investment Strategy;

    Sammanfattning : This thesis investigates the momentum investing strategy during the years 1927 to 2020. The research focuses on both longer time periods and smaller periods of time, more specifically financial crises. This thesis has obtained inspiration from previous research in the area by Jegadeesh and Titman (1993) as well as Daniel and Moskowitz (2016). LÄS MER

  5. 4. Information Disorder och COVID-19 Pandemin: En komparativ fallstudie över datorspel som utbildningsverktyg mot mis-/desinformation i samhället.

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för teknik och estetik

    Författare :Jacob Berglund; Filip Hiller; [2021]
    Nyckelord :4DF; LM-GM; MDA; Research through Design; COVID-19; Annotated Portfolio; Information Disorder;

    Sammanfattning : Denna studie bygger på Research through Design (Frayling, 1993), d.v.s att undersökningen syftar till att generera ny kunskap genom analys av datorspel och design av en gestaltning. För att uppnå detta används ett annoterat portfolio och dess underliggande principer (Gaver, 2012; Bowers, 2012). LÄS MER

  7. 5. Asymptotics of beta-Hermite Ensembles

    Kandidat-uppsats, Linköpings universitet/Matematisk statistik; Linköpings universitet/Tekniska fakulteten

    Författare :Filip Berglund; [2020]
    Nyckelord :beta-Hermite ensembles; Gaussian ensembles; empirical distribution function; level density; largest eigenvalue; order statistic; Sturm sequence; Hermite polynomials; beta-Hermite ensemblerna; gaussiska ensemblerna; empiriska fördelningsfunktionen; nivåtäthet; största egenvärdet; ordningsstatiska; Sturmföljder; Hermitepolynom;

    Sammanfattning : In this thesis we present results about some eigenvalue statistics of the beta-Hermite ensembles, both in the classical cases corresponding to beta = 1, 2, 4, that is the Gaussian orthogonal ensemble (consisting of real symmetric matrices), the Gaussian unitary ensemble (consisting of complex Hermitian matrices) and the Gaussian symplectic ensembles (consisting of quaternionic self-dual matrices) respectively. We also look at the less explored general beta-Hermite ensembles (consisting of real tridiagonal symmetric matrices). LÄS MER
