  1. 1. Incorporating Flax Fiber Composites in Hypercar Panels

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hanna Öster; Sara Isorena Guðjónsdóttir; [2023]
    Keywords : sound transmission loss; coincidence frequency; sound pressure level; flax fibre; carbon fibre; ljudtransmission; koincidensfrekvens; ljudtrycksnivå; linfiber; kolfiber;

    Abstract : This thesis investigates sound transmission loss through flat finite panels using composite materials, which incorporate both carbon and flax fibres. The study wascarried out by performing FEM simulations developed and validated in steps. Thevalidation process was time-consuming but crucial in ensuring the model’s reliability. READ MORE

  3. 2. Dynamic Analysis of Double Tee Floors Subjected to Human Activity : A comparison between a standard- and a modified cross section

    University essay from KTH/Bro- och stålbyggnad

    Author : Bjondina Hoti; Fadi Simonides; [2022]
    Keywords : ;

    Abstract : Building with larger spans and more slender elements is more common today since the demand for open floor plans has increased. The consequence is that low frequency floors and vibration problems arise. Such floors tend to undergo large vibrations since their low eigenfrequency coincides with the frequency which human activities have. READ MORE

  4. 3. Photoionization study using few attosecond pulses and coincidence imaging techniques

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Lisa Rämisch; [2019]
    Keywords : Laser spectroscopy; Attosecond Science; Electron Spectroscopy; Physics and Astronomy;

    Abstract : Photoionization is one of the most fundamental photoreactions that leads to the ejection of an electron and the formation of an ion. With the help of modern 3D momentum imaging spectrometers, the interplay between the time and frequency domain upon ionization is studied. READ MORE
