  1. 21. Beam-steered Modulation in Advanced Antenna System

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Smitha Jinnahalli Venugopal; [2023]
    Nyckelord :5G-MIMO; Beam-forming; Beam-steering; Advanced antenna systems; Technology and Engineering;

    Sammanfattning : The newer spectral bands in millimeter-wave (mm-Wave) spectrum over the last few years have made higher data rates possible and improved quality of service for the users, but it possesses new challenges to design spectral agile radios. Power Amplifiers (PA) are a crucial analog component connected to Multiple input multiple output (MIMO) antennas which inherits non-linear effects. LÄS MER

  3. 22. From Topology Optimized Concept to Detailed Design via Implicit-based Geometries and Non-linear Finite Element Analysis

    Uppsats för yrkesexamina på avancerad nivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Jonatan Gripenberth; [2023]
    Nyckelord :Topologioptimiering; Implicita kroppar; Arbetsflöde; Icke-linjär finita element analys;

    Sammanfattning : A workflow to go from topology optimized concept to a detailed design was created in this thesis. This was done through the use of Implicit-based geometries and Non-linear finite element analysis. LÄS MER

  4. 23. Artificial Intelligence for Option Pricing

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Emil Hietanen; [2022-06-19]
    Nyckelord :Options; calls; puts; pricing; artificial neural networks; models; volatility; comparison;

    Sammanfattning : This thesis addresses the issue of vulnerable underlying assumptions used in option pricing methodology. More precisely; underlying assumptions made on the financial assets and markets make option pricing theory vulnerable to changes in the financial framework. LÄS MER

  5. 24. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Wickramasooriyage Devmini Kularatne; [2022]
    Nyckelord :Oriented strand board; thermal decomposition; mechanical degradation; heat transfer modelling; Technology and Engineering;

    Sammanfattning : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. LÄS MER

  7. 25. FE-modelling of glulam connection in a pre-tensioned glulam truss : Detailed Finite element modelling of the connection between primary beam and compression stud in a sub-tensioned glulam roof truss

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Edward Sebastian Swaretz; [2022]
    Nyckelord :Glulam; sub-tensioned roof truss; connection; instability; Abaqus Standard; Finite element method;

    Sammanfattning : After the collapse of the roof structure in Tarfalahallen 2020, great attention has been focused on instability of sub-tensioned glulam roof trusses. Investigations were launched to find the reason for the collapse and the cause was instability in the roof truss that supported the roof. LÄS MER
