  2. 1. Simulation of rail traffic : applications with timetable construction and delay modelling

    Author : Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). READ MORE

  4. 2. Probabilistic time estimation in tunnel projects

    Author : Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Larsson Stefan; Anna Kadefors; Lars-Olof Dahlström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost overrun; Tunneling projects; Probabilistic approaches; time estimation; Kostnadsöverskridande; tunnelprojekt; sannolikhetsmetoder; tidsuppskattning; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : Transport infrastructure projects, including tunneling, suffer from timedelays and cost overrun. A literature review shows that the effect ofuncertainty has been neglected in explaining time and cost overrunmeaning that technical explanations matter. READ MORE

  5. 3. Wide area monitoring and control systems - application communication requirements and simulation

    Author : Moustafa Chenine; KTH; []
    Keywords : Wide Area Monitoring and Control systems; Phasor Measurements Units; Power System Communication; SCADA systems;

    Abstract : Today’s electrical transmission & distribution systems, are facing a number of challenges related to changing environmental, technical and business factors. Among these factors are, increased environmental restrictions leading to higher share of production from renewable and uncontrollable sources as well as local environmental concerns regarding construction of new transmission and distribution lines.
