  1. 21. Vibrations in cross-laminated timber floors : Examining standards

    University essay from KTH/Byggteknik och design

    Author : Lisette Svensson; Emma Berghem; [2020]
    Keywords : floor vibrations; CLT; timber; vibrations; FEM; Eurocode 5; Calculatis; Bjälklagsvibrationer; KL-trä; vibrationer; FEM; Eurokod 5; calculatis;

    Abstract : The report aims to investigate norms, standards, guidelines and experience within the industry for how to design CLT (cross-laminated timber) regarding vibrations induced from humans. The following is being researched, ISO137, KL-trähandboken, Eurocode 5 and a new unpublished working draft of Eurocode 5 final working draft, Canadian CLT handbook and Cross-laminated timber structural design according to Eurocode from Austria.

  3. 22. Analysis of the energy consumption of the powertrain and the auxiliary systems for battery-electric trucks

    University essay from KTH/Fordonsdynamik

    Author : Guanqiao Song; [2020]
    Keywords : Battery-electric truck; Energy consumption analysis; Battery loss; PT1 battery model; Power Take Off; Sankey diagram; Direct-Current charging; Batterielektrisk lastbil; Energiförbrukningsanalys; Batteriförlust; PT1 batterimodell; Power Take Off; Sankey diagram; Direct-Current charging;

    Abstract : The electrification of the truck is crucial to meet the strategic vision of the European Union (EU) to contribute to net-zero greenhouse gas emissions for all sectors of the economy and society. The battery-electric truck is very efficient to reduce the emissions and has also a lower Total Cost of Ownership (TCO) compared to diesel trucks. READ MORE

  4. 23. Calibration and Estimation of Dog Teeth Positions in Synchronizers for Minimizing Noise and Wear during Gear Shifting

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Qianyin Kong; [2020]
    Keywords : Synchronizer engagement; gear shifting; dog teeth; particle swarm optimization; Synkroniserare; Växling; Dog-teeth; Partikelsvärmoptimering;

    Abstract : Electric motors are used more widely in automotive to reducing emissions in vehicles. Due to the decreased usage of internal combustion engines which used to be the main noise source, impacts from synchronizers cannot be ignored during gear shifting, not only causing noise and wear but also delaying gear shifting completion.

  5. 24. Study of Dark Matter Models in Astrophysics and Particle Physics

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Isabelle John; [2019]
    Keywords : Physics and Astronomy;

    Abstract : From astrophysical and cosmological observations, it is known that most of the matter in the Universe is dark. This matter could be explainable by new particles, not included in the Standard Model of Particle Physics. READ MORE

  6. 25. Finite element modelling of strained nanowire heterostructures

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

    Author : Alexander Grape Wyke; [2019]
    Keywords : Strain; nanowire; heterostructure; physics; nanophysics; COMSOL; simulation; lattice; Physics and Astronomy;

    Abstract : When two materials with different lattice constants are grown together, this generates stress between them, and therefore strain. This strain causes them to have different thermal and electrical properties, and this is especially important on the nanoscale where changes have large impacts. READ MORE
