6. Haulage system optimization for underground mines : A discrete event simulation and mixed integer programming approach
Sammanfattning : In coming decades, many underground mines will operate at greater depths, which will affect many operational factors such as increased rock stress, longer haulage distances, and higher energy consumption, which potentially can generate lower production rates. The increased rock stresses may lead to smaller sized openings, further restricting the size of loading and hauling equipment that can be used. LÄS MER
7. End-user activity-based service design in the built environment context : Exploring everyday life in KTH Live-in-Lab
Sammanfattning : The main goal of this thesis is to communicate the motivation, process, and result of the research project dedicated to exploring the topic of Service Design, based on end-user activities analysis in the built environment context. We have elected to use a KTH Live-in-Lab as a testbed in relation to the chosen living lab network of actors and stakeholders. LÄS MER
8. Systems Dependability Engineering for Wind Power Applications : Challenges, Concepts, and System-Level Methodologies
Sammanfattning : Complexity and uncertainty have impacted wind power systems and their applications.Commercial wind power asset exhibits complex system behaviour due tostochastic loading characteristics of its installation context. However, differentstakeholders’ practices in whole life cycle processes try to treat multi-disciplinarycomplexity issues. LÄS MER
9. Optimal Railroad Power Supply System Operation and Design : Detailed system studies, and aggregated investment models
Sammanfattning : Railway power supply systems (RPSSs) differ mainly from public power systems from that the loads are moving. These moving loads are motoring trains. Trains can also be regenerating when braking and are then power sources. These loads consume comparatively much power, causing substantial voltage drops, not rarely so big that the loads are reduced.

10. Exploring Heavy Vehicle Interaction : Interaction design studies of industrial vehicle operators' information awareness using mixed reality
Sammanfattning : The work presented in this dissertation is in the field of interaction design through visual interaction with information systems in heavy industrial vehicles within agriculture, forestry, and construction. The dissertation investigates how interaction technologies and the application of interaction design methods can be used to provide an efficient interaction and a good user experience for the operator interacting with the heavy vehicle information system.
