  1. 11. Dynamic Analysis of Portal Frame Railway Bridges - Case Studies Investigating the Structural Response

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Benjamin Berg; Pontus Nyberg; [2020]
    Keywords : Dynamic Analysis; Portal Frame Bridges; High Speed Trains; Railway Bridges; Finite Element; Resonance; Modal Analysis; BRIGADE Plus; Technology and Engineering;

    Abstract : As the world continues to see an increase in carbon dioxide emissions, actions aiming towards reducing man's negative impact on the environment are paramount. To be able to compete with the air travel industry, the Swedish Transport Administration suggests a vast expansion of the existing railway system. READ MORE

  3. 12. Making Hypervelocity Stars

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Frans Forsberg; [2020]
    Keywords : Stellar Dynamics; Binary Stars; Galactic Centre; Binary Relaxation; Physics and Astronomy;

    Abstract : In this thesis, I investigate if the binaries that are being tidally disrupted by means of the Hills mechanism, producing hypervelocity stars, could have been transported to the galactic centre by two-body scattering. To survive a scattering event, the binary must be hard, meaning that the binding energy of the binary is higher than the kinetic energy of the collider. READ MORE

  4. 13. Thermoset biopolymer reinforced with carbon-nanotubes

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Morteza Esmaeili; [2019]
    Keywords : biopolymers; bio-composites; glycerol lactic acid; carbon nanotube; reinforcement; thermoset; dispersion;

    Abstract : Compared to conventional fibers, carbon nanotubes possess several significant properties, which make them as an excellent alternative reinforcement in multi-functional material industry. In this study, the possibility of dispersion of the multi-wall carbon nanotube (MWCNTs) in a thermoset bio-based resin (synthesized based on end-functionalized glycerol-lactic acid oligomers, GLA, at university of Borås) was investigated.

  5. 14. Dynamic Design of Bridges on High-Speed Railway Lines

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

    Author : Felicia Nilsson; Filippa Dahl; [2019]
    Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

    Abstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE

  6. 15. Distance Control of Heavy-Duty Vehicle Platooning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ali Madadi; [2019]
    Keywords : ;

    Abstract : Vehicle platooning is a modern technique which enables us to have a group ofvehicles driving in a cooperative way. More specifically, in vehicle platooning, anumber of vehicles uses a common control system and inter-vehiclecommunications to cooperatively drive close to each other and in a high speed. READ MORE
