  1. 1. Life extension of welded steel details in bridges

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

    Författare :Zhelei Jin; [2023]
    Nyckelord :Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

    Sammanfattning : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. LÄS MER

  3. 2. Conservatism in Credit Ratings: A Comparative Study of Time-Varying Credit Rating Standards in Europe and the US, 1997-2023

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

    Författare :Ebba Bogfors; Elsa Persson; [2023]
    Nyckelord :Credit ratings; Rating quality; Rating conservatism; Rating standards;

    Sammanfattning : Our paper reveals increased conservatism in credit ratings in both Europe and the US from 1997 to 2023, with the effect stabilizing after the financial crisis. On average, ratings have declined by more than three notches in Europe, signifying that a firm rated AAA in 1997, with constant financial characteristics, would receive a rating of AA- in 2023.

  4. 3. A Travelling Wave Slot Array based on a Double-Layer Lens for 77 GHz Automotive Radar

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

    Författare :Ashray Ugle; [2023]
    Nyckelord :Automotive radar; Double-layer lens; Gap waveguide technology; Waveguide slot; Antenna array; Lens-beamforming.; Bilradar; Dubbelskiktslins; Gap-vågledarteknik; Waveguide-kortplats; Antennuppsättning; Lens-beamforming.;

    Sammanfattning : Automotive radars have gained considerable interest in recent years for applications of road safety for vulnerable road users. The use of multipleinput and multiple-output (MIMO) technology in automotive radar has helped in realising a virtual aperture greater than the physical aperture of the antenna which has reduced the size of the overall radar module.

  5. 4. LED-armband för festival-användning

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

    Författare :Linnéa Petersson; Sofia Ramserdal; [2023]
    Nyckelord :;

    Sammanfattning : Spektrer är ett nystartat företag som skapar musikfestival-tillbehör. Deras teknik handlar om att låta produkten reagera på ljudet i realtid och skapa en ljusupplevelse med hjälp av LED-lampor. LÄS MER

  7. 5. Model-based synthesis of singing

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

    Författare :Xiaofeng Zeng; [2023]
    Nyckelord :Singing voice synthesis; Source-filter model; Anti-resonances; SuperCollider; Sång röstsyntes; Käll-filtersmodell; Anti-resonanser; SuperCollider;

    Sammanfattning : The legacy KTH Music and Singing Synthesis Equipment (MUSSE) system, developed decades ago, is no longer compatible with contemporary computer systems. Nonetheless, the fundamental synthesis model at its core, known as the source-filter model, continues to be a valuable technology in the research field of voice synthesis. LÄS MER
