  1. 1. Comparison of Electric Aircraft and Electric Train : On the Distance Stockholm-Gothenburg

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Therese Bäckström; [2021]
    Nyckelord :;

    Sammanfattning : Commercial aviation accounts for 2,4% of the total carbon dioxide emissions. This number is expected to reach 25% in 2050. In contrast to flying, the most energy efficient transportation mode is rail. In Sweden, rail and air are the most competitive on the distance Stockholm-Gothenburg due to similar total travel time.

  3. 2. Analys av pantograf WBL 88

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Vincent Castellano; Albin Einarsson; Petter Norder; [2013]
    Nyckelord :;

    Sammanfattning : På uppdrag av Järnvägsgruppen på KTH skulle interaktionen mellan kontaktledning och pantograf simuleras och analyseras. Detta för att kunna presentera ett förbättrat konstruktionsförslag på pantografen som skulle leda till en jämnare kontaktkraft vid höghastighetsdrift, 300 km/h. LÄS MER

  4. 3. LTE MIMO Performance Measurements on Trains

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Mohammad Alasali; [2012]
    Nyckelord :;

    Sammanfattning : Providing passengers internet on board trains with continuous connectivity at high speeds and over large rural distances is a challenging issue. A promising solution to the problem is to use an on board WI-FI network combined with a cellular radio system connected to the LTE (long term evolution) 900/800MHz networks deployed outside the train.

    Sammanfattning : Abstract The Swedish railway has during many years received low customer satisfaction scores. Reasons for this are reliability, service and information concerns. The focus of this master thesis lies on the railway platform. LÄS MER

  7. 5. Travel demand forecasting with stated choice data. : Swedish domestic long-distance trips.

    Master-uppsats, KTH/Transportvetenskap

    Författare :Qian Wang; [2011]
    Nyckelord :;

    Sammanfattning : The travel demand forecasting capability is affected by the model performance and is restricted by the available modes. The Sampers models being used in long distance travel demand forecasting doesn’t deal with nonlinearity and contains no travel service qualitative variables. LÄS MER
