21. Efficient commuter craft for urban waterborne public transportation
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
22. Driverless trucks in the Swedish freight transport system : An analysis of future impacts on the transport system and the emerging innovation system
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.

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

24. Transport systems meeting long-term climate targets : A backcasting approach
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
25. Gait re-education in transfemoral amputees The training programme, gait analysis, oxygen consumption and coping
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
