  3. 12. Utilisation of hardwood in cross-laminated timber - A numerical study on vibrations in floors

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Johannes Jonasson; Olle Karlsson; [2022]
    Keywords : hardwood; birch; beech; clt; cross-laminated timber; vibrations; floors; footfall; accelerations; Technology and Engineering;

    Abstract : Cross-laminated timber (CLT) is an engineered wood product consisting of several layers of laminations bonded together with adhesives. In contrast to heavier construction materials, timber and other lightweight building materials are more prone to serviceability issues due to vibrations. READ MORE

  4. 13. Changes in cetacean presence and behavior in response to reduced marine traffic - the effects of a nationwide lockdown

    University essay from Högskolan i Halmstad

    Author : Lisa Falk Lindberg; Lindqvist Erika; [2022]
    Keywords : ;

    Abstract : Creating noise-pollution and other disturbances, marine traffic poses a great threat to marine mammals all over the world which may demonstrate through short- and long-term changes in behavior and distribution. The Covid-19 lockdown in 2020 provided a setting to study the effects of marine traffic on cetacean presence and interactive behavior. READ MORE

  5. 14. Implementation of battery energy storage systems in the Swedish electrical infrastructure

    University essay from KTH/Kemiteknik

    Author : Gustav Arnberg; [2022]
    Keywords : Battery energy storage systems; BESS; Li-ion batteries; Frequency regulation; Business case; Implementation of battery energy storage systems; Swedish electrical infrastructure; BESS; Li-jon batterier; Frekvensreglering; Affärsfall; Implementering av batterilagringssystem; Svensk elinfrastruktur;

    Abstract : Detta examensarbete utreder den tekniska och ekonomiska passbarheten av batterilagringssystem (BESS) inom den svenska el infrastrukturen. Syftet är att konstruera tre olika affärsfall för att representera den tekniska och den ekonomiska passbarheten av BESS inom den svenska el infrastrukturen, specifikt med uppkoppling mot distributionsnätverket på den regionala nivån, 6 kilovolt till 132 kilovolt (kV).
