  1. 1. Harmonised traffic load model between Eurocode 1 - part 2 (EN 1991-2) and TRV specifications : A pilot study on reinforced concrete portal frame bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Mubashar Amir Ablahad; Nuredin Rasslan; [2023]
    Keywords : ;

    Abstract : The advancement of society has led to an increase in demand for infrastructure, particularly bridges, which are designed in accordance with different design codes. In Sweden, bridge design adheres to the Eurocode and national code (TRV specifications), with the most adverse scenario of the two codes determining the basis for bridge design. READ MORE

    Keywords : Alpha-iron; Chromium carbide; Cr7C3; Fe; Theoretical investigation; Orthorhombic; X-ray diffraction pattern; XRD; VASP; VESTA; Body-centered-cubic; Ferrite; Density functional theory; DFT; Surface relaxation; Simulation; Calculation; Energy relaxation; Slab models; Coherency; Surface energy; Interfacial energy; Alfa-järn; Kromkarbid; Cr7C3; Fe; Teoretisk undersökning; Ortorombisk; Röntgendiffraktion; XRD; VASP; VESTA; Ytenergi; Koherent; Simulering; Beräkning; Järnkarbid; DFT; Täthetsfunktionalanalys;

    Abstract : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). READ MORE

  4. 3. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Fredrik Plane; [2022]
    Keywords : Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

    Abstract : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. READ MORE

  5. 4. Composite timber structures – Ribbed plate design : Evaluation of existing and development of new design methods

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Cristoffer Mård; [2022]
    Keywords : Ribbed plates; CLT; gamma-method; Timoshenko-method; shear analogy-method; FE-models; RFEM; Abaqus;

    Abstract : Ribbed plates comprising cross-laminated timber slab, CLT, with glulam beams allow for increased span length compared to pure CLT slabs. At the moment the Eurocodes do not provide any recommendations to design a CLT plate or a ribbed plate. There are handbooks for designing ribbed plates. READ MORE

  6. 5. Neural Networks for Material Decomposition in Photon-Counting Spectral CT

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Hugo Charrier; [2022]
    Keywords : PCCT; X-ray; scanner; photon counting; AI; neural networks;

    Abstract : Photon counting computed tomography scanners constitute a major improvement of the field of computed tomography, opening various prospective and enabling the decomposition of computed tomography images into different materials. The material decomposition algorithm, mapping photon counts to material pathlengths, relies on a forward model with Poisson statistics. READ MORE
