  1. 1. FE-Modelling of Composite Girder tests

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Holger Berggren; Bergstedt Ola; [2024]
    Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER

  3. 2. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Siddharth Suresh Sumathi; [2023]
    Nyckelord :Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Sammanfattning : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. LÄS MER

  4. 3. Highway Traffic Forecasting with the Diffusion Model : An Image-Generation Based Approach

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Pengnan Chi; [2023]
    Nyckelord :Diffusion model; Traffic forecasting; Generative model; Image processing; Spatial temporal modelling; Diffusionsmodell; Trafikprognos; Generativ modell; Bildbehandling; Rumsligtemporal modellering;

    Sammanfattning : Forecasting of highway traffic is a common practice for real traffic information system, and is of vital importance to traffic management and control on highways. As a typical time-series forecasting task, we want to propose a deep learning model to map the historical sensory traffic values (e.g., speed, flow) to future traffic forecasts. LÄS MER

  5. 4. Modelling the Occurrence and Fate of Microplastics Caused by Tyre Wear on Highway E18

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Aniruddha Kshirsagar; [2023]
    Nyckelord :Tyre Wear Plastics; stormwater system; Microplastics; settling; hetero-aggregation; modelling; Modellering; mikroplaster;

    Sammanfattning : The accumulation of microplastics (MPs) are a growing concern for the environment, the maximum contributor to the MP pollution is tyre wear particles or TWPs. TWPs can accumulate in the environment and remain there for long periods of time and hence have the ability to disrupt ecosystems. LÄS MER

  7. 5. Developing transport interaction macromodels to simulate traffic patterns : Case of Oslo, Norway

    Master-uppsats, KTH/Transportplanering

    Författare :Omkar Parishwad; [2022]
    Nyckelord :Spatial Interaction Modelling; Transport Modelling; City Planning; OD Matrices; Trip distribution; Transport Simulations; Sustainable Development Goals;

    Sammanfattning : Predicting the passenger flow inside a city is a vital component of the intelligent transportation management system. The proposal for a new residential area, an office space, post­pandemic policy implications for work from home, behavioral changes for revised traffic patterns, infrastructural improvements, require a visual and analytical backing which can be provided through a macro simulation model.
