  1. 1. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

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

    Författare :Zhenyu Li; [2023]
    Nyckelord :mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

    Sammanfattning : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. LÄS MER

  3. 2. Room Impulse Response Interpolation

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

    Författare :Daníel Thor Wilcox; [2023]
    Nyckelord :Virtual Acoustics; Machine Learning; Signal Processing; Room Impulse Response; Virtuell Akustik; Maskininlärning; Signalbehandling; rumsimpulssvar;

    Sammanfattning : In Virtual Reality (VR) systems, the incorporation of acoustics allows for the generation of audio-visual stimuli, facilitating applications in engineering, architecture, and design. The goal of virtual acoustics is to create a realistic sound field in continuous space. LÄS MER

  4. 3. Machine learning for detecting fraud in an API

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

    Författare :Anna Sánchez Espunyes; [2022]
    Nyckelord :Fraud detection; Machine learning; Supervised learning; Sentence-BERT; Web API; Bedrägeriupptäckt; Maskininlärning; Övervakad inlärning; Sentence-BERT; Web API;

    Sammanfattning : An Application Programming Interface (API) provides developers with a high-level framework that abstracts the underlying implementation of services. Using an API reduces the time developers spent on implementation, and it encourages collaboration and innovation from third-party developers. LÄS MER

  5. 4. A literature study on measurement methods for calculating the FeO activity in slag

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Rebecca Rosén; [2020]
    Nyckelord :;

    Sammanfattning : During the time we live in, climate change is more important than ever. HYBRIT, formed bySSAB, LKAB, and Vattenfall, is an initiative set out to make the steel production fossil free, by developing a novel process that produce direct reduced iron (DRI) using hydrogen as reagent. Electric arc furnaces (EAF) will then be employed to melt the DRI. LÄS MER

  7. 5. A Numerical Calculation Tool Design for the Performance Assessment of a Bench-Scale Thermochemical Heat Storage System

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :DIYUE WANG; [2020]
    Nyckelord :Calculation tool; SrCl2-NH3; Performance evaluation; Mass; Energy; Beräkningsverktyg; SrCl2-NH3; Prestandasutvärdering; massa; energi;

    Sammanfattning : Thermochemical heat storage (TCS) is a technology to convert the heat and cold energy into chemical energy, via reversible chemical reactions, to be stored for heating and cooling applications. TCS technology is gaining interest for its very compact energy storage densities offering attractive thermal energy storage (TES) alternatives to decrease energy-related greenhouse gas(GHG) emissions and contribute to sustainable development.
