  1. 1. Spectral density approach for dynamic analysis of high-speed railway bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Alket Ciku; Vlad Gavriliuc; [2022]
    Keywords : ;

    Abstract : The focus of this thesis is to introduce the concept of train signature in the spectraldensity approach used in the dynamic analysis of simply-supported railway bridges.Due to the increased transportation demands, longer trains with higher axles loadsand top speeds are being developed.

  3. 2. Tuning of the ESS Drift Tube Linac using Machine Learning

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Author : Johan Lundquist; [2022]
    Keywords : Accelerator; drift tube linac; machine learning; neural network; ESS; linac; tuning; proton; longitudinal dynamics; beam physics; Physics and Astronomy;

    Abstract : The European Spallation Source, currently under construction in Lund, Sweden, will be the world's brightest neutron source. It is driven by a linear accelerator designed to accelerate a beam of protons with 62.5 mA, 2.86 ms long pulses, working at 14 Hz. READ MORE

  4. 3. contradictions of Transit Oriented Development (TOD) in low-income Neighborhoods: the case study of Rosengard, Malmo

    University essay from Malmö universitet/Fakulteten för kultur och samhälle (KS)

    Author : derakhti Laleh; [2019]
    Keywords : Transit-Oriented Development TOD ; Transit-Induced Gentrification; displacement; affordable housing; segregation; Rosengård.;

    Abstract : Transit-Oriented Development (TOD) is known as a mixed-use development near and oriented to public transport facilities. While TOD has become a predominant model of urban planning based on the idea that there will be both social and economic benefits of implementation, the recent popularity of TOD in many cities has provided a new focus for the gentrification–displacement debate as well as affordability paradox.

  5. 4. Optimal Design of Bridges for High-Speed Trains : Single and double-span bridges

    University essay from KTH/Bro- och stålbyggnad; KTH/Järnvägsgruppen, JVG

    Author : Carine Mellier; [2010]
    Keywords : Optimization; Vertical deck acceleration; Railway bridges; High-speed trains; Train Signature; Finite element analysis;

    Abstract : To deal with an increasing demand in transportation, trains are made longer and faster. Higher speeds imply higher impacts on bridges. Therefore, structures have to be designed to resist these new constraints. The Eurocode (2002) introduced additional checks for the design of high-speed railway bridges. READ MORE
