  1. 1. Modelling the Exchange Rate: Evidence from the Impacts of Quantitative Easing in Sweden

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Anny Eklund; Markus Sallkvist; [2024]
    Nyckelord :Quantitative easing; Exchange rate; Bayesian VAR model; Small open economy; Triangular factorisation;

    Sammanfattning : Quantitative easing, the unconventional monetary policy measure used by many central banks to combat low inflation when interest rates are at the lower bound, has shown to be an effective tool for depreciating the domestic currency. Although the exchange rate is of particular importance in a small open economy as it directly impacts inflation dynamics,trade competitiveness and plays a substantial role in shaping monetary policy, few papers have investigated how the depreciating effect of QE to the exchange rate works.

  3. 2. Using search based methods for beamforming

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Adam Bergman Karlsson; [2024]
    Nyckelord :Beamforming; Artificial Intelligence; AlphaZero; Radio Resource Management; Monte Carlo Tree Search;

    Sammanfattning : In accommodating the growing global demand for wireless, Multi-User Multiple-Input and Multiple-Output (MU-MIMO) systems have been identified as the key technology. In such systems, a transmitting basestation serves several users simultaneously, increasing the network capacity. LÄS MER

  4. 3. Scrollande hjärnor, kalkylerade annonser: en studie om konsumenters attityder till algoritmisk marknadsföring i sociala medier och dess bakomliggande faktorer

    Kandidat-uppsats, Göteborgs universitet/Företagsekonomiska institutionen

    Författare :Arvid Barregren; Louise Bergendahl; [2023-11-07]
    Nyckelord :algorithms; digital marketing; social media; TAM; attitudes; knowledge; relevance; integrity; trust;

    Sammanfattning : Existing literature argues that with the commercialisation of the Internet, marketing has moved from a physical activity to a fluid and digital one. Over time, social media has become a central and important channel for reaching consumers, which has fundamentally changed the way marketing is conducted today. LÄS MER

  5. 4. Heart rate estimation from wrist-PPG signals in activity by deep learning methods

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marie-Ange Stefanos; [2023]
    Nyckelord :Deep Learning; Medical Data; Signal Processing; Heart Rate Estimation; Wrist Photoplethysmography; Djup lärning; Medicinska Data; Signalbehandling; Pulsuppskattning; Handledsfotopletysmograf;

    Sammanfattning : In the context of health improving, the measurement of vital parameters such as heart rate (HR) can provide solutions for health monitoring, prevention and screening for certain chronic diseases. Among the different technologies for HR measuring, photoplethysmography (PPG) technique embedded in smart watches is the most commonly used in the field of consumer electronics since it is comfortable and does not require any user intervention.

  7. 5. Computational Fluid Dynamics and Modeling of a Free Surface Flow

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Mathieu Marmier; [2023]
    Nyckelord :CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Sammanfattning : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. LÄS MER
