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

    Author : Erik Kongpachith; [2023]
    Keywords : Railway freight Transport; Rail Vehicle Weighing; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Machine Learning; Regression; Polynomial Regression; Regression Trees; Random Forest Regression; Support Vector Regression; Järnvägsgods transport; Vägning av järnvägsfordon; Y25 Bogie; Sdggmrss T3000eD; GENSYS; Maskininlärning; Regression; Polynom Regression; Regressionsträd; Random Forest Regression; Support Vector Regression;

    Abstract : Accurate estimation of the load weight of freight trains is crucial for ensuring safe, efficient and sustainable rail freight transports. Traditional methods for estimating load weight often suffer from limitations in accuracy and efficiency. READ MORE

  3. 2. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model

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

    Author : Alexander Adolfsson; [2022]
    Keywords : Black-Box Optimisation; Optimization; Simulation based optimisation; Transit Network; Automaton; Urban Transport; Public transportation; Black-Box optimering; Optimering; Simuleringsbaserad Optimering; Transportsystem; Automation; Local Transport; Kollektivtrafik;

    Abstract : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. READ MORE

  4. 3. The Effect of High Wheel Impact Load on the Rail Reliability - a Case Study at Bodsjön

    University essay from KTH/Spårfordon

    Author : Ngoc Thúy Vy Dang; [2021]
    Keywords : rail defects; rail reliability; Ultrasonic Test; wheel damage; Wheel Impact Load Detector; statistics; järnvägsdefekter; järnvägssäkerhet; ultraljudstest; hjulskador; hjullastningsdetektor; statistik;

    Abstract : This study focuses on the reliability of railway track in the relation with high loads resulted from wheel damages, where higher (dynamic) vertical wheel loads are expected from trains with damaged wheels. The Swedish Transport Administration (Trafikverket) has monitored and recorded data of rail defects and breaks. READ MORE

  5. 4. Influence of load distribution on trough bridges

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Gustafsson; [2021]
    Keywords : Bridge; Trough bridge; Concrete; Load distribution; Ballast;

    Abstract : There are approximately 4000 railway bridges in Sweden and a common construction type is the short span concrete trough bridge. With the current standards the load distribution through ballast is assumed to be uniformly distributed with a distribution slope of 2:1 according to the Swedish Administration of Transport or 4:1 according to Eurocode 1.

  6. 5. Floor Guide for Sliding Doors

    University essay from Lunds universitet/Innovation

    Author : Elin Friberg; Jennie Walfridson; [2020]
    Keywords : Product development; Assa Abloy; floor guide; friction; noise; Technology and Engineering;

    Abstract : This Master Thesis, executed in collaboration with Assa Abloy Entrance Systems, addresses issues and desirable features with the currently used floor guide, and several final concepts, in terms of short-term and mid-term solutions, are presented after following the product development process. The floor guide's main purpose is to keep the door leaves of an automatic sliding door running smoothly on correct track without causing any noise. READ MORE
