  1. 21. Volatility & The Black Swan : Investigation of Univariate ARCH-models, HARRV and Implied Volatility in Nasdaq100 amid Covid19

    Master-uppsats, Uppsala universitet/Nationalekonomiska institutionen

    Författare :Karl Tingstedt; [2022]
    Nyckelord :SV; ARCH; GARCH; TARCH; EGARCH; HARRV; IV; RV; Integrated Volatility; TINA;

    Sammanfattning : Covid19 hit the world’s financial markets by surprise in March 2020 and ensuing volatility marked an end to the prior low-volatility environment. This Black Swan engendered numerous publications establishing how the equity market responded to the exogenous shock. LÄS MER

  3. 22. Improving the Robustness, Thermal and Noise Performance of a Radio Transmitter Fan Tray

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Mattias Olausson; Selma Rahman; [2022]
    Nyckelord :Fan tray; Heat dissipation; Robustness; Radio transmitter; Noise performance; Fläktlåda; Värmeavledningsförmåga; Robusthet; Radio sändare; Ljudprestanda;

    Sammanfattning : With the growing demand of compact radio transmitters, so do the need for silent and efficient thermal management systems. Given the restricted form-factor, ensuring robustness of a unit with a detachable fan tray imposes a challenge. LÄS MER

  4. 23. Sound Source Localization for an Urban Outdoor Setting : A Systematic Review

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :Anna Malmgren; [2022]
    Nyckelord :sound source localization; outdoor localization; state of the art SSL;

    Sammanfattning : Sound source localization (SSL) is a broad field, with many important application areas. In outdoor environments SSL systems can, among other things, be used to increase citizens’ safety by detecting and locating abnormal sounds such as gunshots or screams. LÄS MER

  5. 24. Estimating Believed Knowledge of Portfolio Agents Using Inverse Optimization

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

    Författare :Gustaf Zachrisson; Oscar Wink; [2022]
    Nyckelord :;

    Sammanfattning : In this report, we demonstrate the utility of inverse optimization in convex programming by applying it on estimating financial market beliefs and behaviors of portfolio investors. The inversion of the optimization  utilized the Karush–Kuhn–Tucker optimality conditions specified for the current situation. LÄS MER

  7. 25. Extension of an Existing Simulator for Cellular Communication with Support for 5G NR : Porting of MIMO Channel Estimation Methods form a prototype to an existing Link-Level Simulator

    M1-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Författare :Majed Haj Hussein; Abdulsalam Alnahawi; [2022]
    Nyckelord :5G NR; Channel Estimation; MIMO; OFDM; DMRS;

    Sammanfattning : Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are two efficient technologies used to achieve higher data rate, lowlatency, robustness against fading used in 5G New Radio (NR). At the receiver end,the data arrives distorted due to disturbance during transfer over the wireless channel. LÄS MER
