    Författare :Harsha Cheemakurthy; Karl Garme; Joakim Kalantari; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waterborne public transportation; commuter ferry; modular design; operational requirements; ranking method; sustainable performance; ice operations; ice-hull Interaction; ice load; ice properties; kollektivtrafik på vatten; modulärt färjekoncept; modulär design; rankningsmetod; hållbarhetsparametrar; isbelastning; isförhållanden; isegenskaper; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : There has been a recent surge in interest in waterborne public transportation (WPT). Publictransport providers (PTP) are seeing its potential in complementing the existing transportnetwork and alleviating urban traffic congestion and pollution. But the adoption of WPTtoday is challenging due to a series of technical and implementation challenges. LÄS MER

  2. 22. Driverless trucks in the Swedish freight transport system : An analysis of future impacts on the transport system and the emerging innovation system

    Författare :Albin Engholm; Anna Pernestål; Ida Kristoffersson; Maria Oscott; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driverless Trucks; Automated Driving; Total Cost of Ownership; Freight Transport Modeling; Innovation Systems; Machine Design; Maskinkonstruktion;

    Sammanfattning : A large-scale introduction of driverless trucks could start taking place during the next decade. While this could bring several economic benefits for freight transport actors and society, it may also change the freight transport system and exacerbate the negative effects of road transport.

  3. 23. Simulation-based Evaluation of Fixed to Flexible Transit

    Författare :David Leffler; Erik Jenelius; Wilco Burghout; Oded Cats; Chris Tampère; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : Emerging technologies have inspired a wide array of flexible public transit system designs characterized by varying degrees of demand-responsive routing and scheduling. The availability and synthesis of new data sources with higher degrees of spatial and temporal richness brought on by advancements in Intelligent Transport Systems allow for monitoring and responding to evolving supply-demand imbalances in real-time.

  4. 24. Transport systems meeting long-term climate targets : A backcasting approach

    Författare :Jonas Åkerman; Mattias Höjer; Glenn Lyons; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Other social sciences; Övrig samhällsvetenskap;

    Sammanfattning : Future transport systems consistent with long-term climate targets are examined in this thesis, using a systems perspective covering the entire transport system. Aviation is given particular attention, as expansion of this mode is difficult to reconcile with climate targets. LÄS MER

  5. 25. Gait re-education in transfemoral amputees The training programme, gait analysis, oxygen consumption and coping

    Författare :Catharina Sjödahl Hammarlund; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical medicine; kinesitherapy; revalidation; rehabilitation; a psychologically conscious therapeutic approach; coping; energy cost; oxygen consumption; motion analysis; gait speed; amputees; training; gait re-education; Rehabilitering medicinsk och social ;

    Sammanfattning : A gait re-education programme, combining physiotherapy with a psychologically conscious therapeutic approach, was applied to nine unilateral transfemoral amputees, whose amputation was caused by trauma or tumour. The participants trained once a week for a mean 10 months. The median age was 33 years (range 16– 51). LÄS MER
