  1. 1. Do not let bad maintenance ruin your day : A case study of coordinating turnaround maintenance in a continuous flow process industry.

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Andrew Hlebnikovs; Axel Kövamees; [2022]
    Nyckelord :Turnaround maintenance; Continuous flow process industry; Preventive maintenance; Maintenance coordination; Maintenance management;

    Sammanfattning : The uptime of machinery in continuous flow process industries such as steel manufacturing plants puts pressure on the maintenance function. This in turn contributes to sustaining reliable physical assets. As absence of reliable physical assets highly affects the competitive advantage. LÄS MER

  3. 2. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Johan Kövamees; [2020]
    Nyckelord :Electrically Steerable Phased-Arrays for 5G Sub-6 GHz Massive MIMO Active Antenna Units;

    Sammanfattning : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. LÄS MER

  4. 3. There is such a thing as a free lunch, but it will cost you: a study on costly arbitrage and the index effect

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

    Författare :Sandra Andersson; Nicklas Kövamees; [2019]
    Nyckelord :arbitrage risk; demand curve slopes; index effect; market efficiency; transaction costs;

    Sammanfattning : This thesis examines how stock returns around inclusions into and exclusions from the Swedish OMX Stockholm Benchmark and OMX Stockholm 30 indices are affected by arbitrage risk and transaction costs. We observe that during the 30 trading days preceding the announcement of a stock's inclusion in either index, stocks with high arbitrage risk and high transaction costs experience high positive abnormal returns, and vice versa.

  5. 4. Particle-based Stochastic Volatility in Mean model

    Master-uppsats, KTH/Matematisk statistik

    Författare :Gustav Kövamees; [2019]
    Nyckelord :Stochastic volatility model; Volatility feedback theory; hidden Markov model; particle filter; Expectation-Maximization algorithm; PaRIS-algorithm; Stokastisk volatilitets modell; dold Markov modell; partikel-filter; Förväntan-Maximering algorithm; PaRIS-algoritm; volatilitets-återkopplings-teori;

    Sammanfattning : This thesis present a Stochastic Volatility in Mean (SVM) model which is estimated using sequential Monte Carlo methods. The SVM model was first introduced by Koopman and provides an opportunity to study the intertemporal relationship between stock returns and their volatility through inclusion of volatility itself as an explanatory variable in the mean-equation.

  7. 5. A Statistical Study of How Different Factors and the Availability of High-Speed Internet Affect Housing Prices

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Gustav Kövamees; Sanna Penton; [2017]
    Nyckelord :;

    Sammanfattning : This paper presents an empirical study of the impact of different factors on real estate sales prices in the countryside of Sweden. Further, this thesis analyzes the value of broadband to Swedish households examining whether access to fiber is correlated with higher real estate sales prices. LÄS MER
