21. On Energy Management Strategies for Hybrid Electric Vehicles
Sammanfattning : Hybrid electric vehicles are characterized by the existence of an electric energy buffer in the powertrain. Compared to a conventional vehicle the existence of the buffer means an extra degree of freedom in the powertrain. LÄS MER
22. High volumetric machining strategies for superalloy gasturbine components : Comparing conventional and nonconventional machining methods for efficient manufacturing
Sammanfattning : There is a strong industrial driving force to find alternative manufacturing technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies, as well as enhanced utilisation of today's high volumetric manufacturing, allows taking a leap to increase the material removal rate and the productivity.

23. Motion modelling and control strategies of over-actuated vehicles
Sammanfattning : With the growing concern for environmental change and uncertain oil resources, the development of new vehicle concepts will in many cases include full or partial electric propulsion. The introduction of more advanced powertrains enables vehicles that can be controlled with a variety of electric actuators, such as wheel hub motors and individual steering. LÄS MER
24. Dagligvarudistributionens strukturomvandling : Drivkrafter och konsekvenser för städers utformning och miljö
Sammanfattning : The purpose of this study is to describe and analyse the dramatic structural changes in the wholesaling and retailing of food and groceries in towns and cities in Sweden, with emphasis on the period after the Second World War. Besides a general analysis based on national data, the town of Linköping is used to illustrate the spatial dimension in the development of food distribution at the micro level. LÄS MER
25. Optimal Control of Electric Bus Lines
Sammanfattning : Bus lines are inherently unstable systems, where any delay tends to be further amplified by the accrued passenger loads encountered at stops downstream. This self-reinforcing mechanism, when combined with the multiple sources of disturbances of an urban environment, can lead to the problem of bus bunching. LÄS MER
