  1. 1. Optimerat bjälklag av korslimmat trä genom styvare virke i ytterlameller

    Uppsats för yrkesexamina på avancerad nivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Frida Kjellberg; Sofia Bergman; [2023]
    Nyckelord :CLT; floor panel; design principles; optimization; stiffness; vibrations; KL-trä; bjälklag; dimensionering; optimering; styvhet; vibrationer;

    Sammanfattning : Användningen av trä som byggmaterial i stomsystem har ökat markant. I takt med att förfrågan ökar, blir det allt mer relevant att undersöka hur materialet kan utnyttjas optimalt. Av KL-träbjälklag som tillverkas idag, är majoriteten homogena och tillverkade av konstruktionsvirke med hållfasthetklass C24. LÄS MER

  3. 2. Measurement of mechanical vibrations : Measurement of ambient energy in the form of mechanical vibrations in transportation, storage and installment for the use of self-powered wireless sensor networks

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

    Författare :Oskar Nordström; [2023]
    Nyckelord :;

    Sammanfattning : This project aims to explore the feasibility of using energy harvesting to create a self-powered sensor node that doesn't require batteries. The project was initiated by Ericsson, who identified a need to monitor their radio products during delivery to ensure they are not damaged by vibrations that exceed design specifications. LÄS MER

  4. 3. Predicting comfort in autonomous driving from vibration measurements using machine learning models

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Kate Asarar; [2021]
    Nyckelord :Passenger comfort; Machine learning; Autonomous driving; Vibrationer; Passagerarkomfort; Maskininlärning; Vibrationer; Självkörande bilar;

    Sammanfattning : Highly automated driving is approaching reality at a high speed. BMW is planningto put its first autonomous driving vehicle on the road already by 2021. The path torealising this new technology is however, full of challenges. LÄS MER

  5. 4. Level 1 processing  algorithms of MicroCarb  microsatellite : Performance assessment of ISRF in-flight estimation through new algorithms

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

    Författare :Quentin Taupin; [2021]
    Nyckelord :;

    Sammanfattning : Facing global warming and its dramatic consequences, it is now of the utmost urgency to improve our understanding of the carbon cycle mechanisms through which global climate change unfolds. The MicroCarb mission will allow to accurately monitor CO2 global sources and sinks over the entire surface of the Earth. LÄS MER

  7. 5. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Carl Järmyr Eriksson; [2021]
    Nyckelord :Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

    Sammanfattning : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. LÄS MER
