11. Uttryck på schemat och intryck i klassrummet : En studie av lektioner i skolor utan timplan
Sammanfattning : Syftet med föreliggande avhandling är att studera användning och förekomst av lektionsbeteckningar på scheman i skolor utan en nationellt fastställd timplan, samt belysa hur elever upplever de lokala val som görs vad gäller vissa av dessa lektionsbeteckningar. Den teoretiska referensramen har sin grund i didaktikens selektionsfråga och kommunikationsfråga, och Bernsteins båda begrepp klassifikation och inramning. LÄS MER
12. Quality on single-track railway lines with passenger traffic : Anlytical model for evaluation of crossing stations and partial double-tracks
Sammanfattning : Railway transportation is showing a substantial increase. Investments in new infrastructure, new fast and comfortable vehicles, and high frequency of service are important factors behind the increase.Infrastructure configuration and timetable construction play important roles in the competitiveness of railway transportation.

13. Optimization-Based Methods for Revising Train Timetables with Focus on Robustness
Sammanfattning : With increase in the use of railway transport, ensuring robustness in railway timetables has never been this important. In a dense railway timetable even a small disturbance can propagate easily and affect trains' arrival and departure times. In a robust timetable small delays are absorbed and knock-on effects are prevented effectively. LÄS MER
14. Optimisation models for train timetabling and marshalling yard planning
Sammanfattning : Railways provide high capacity, safe and energy efficient transportation of goods and passengers. However, railway transportation also suffers from intrinsic restrictions and the effectiveness and efficiency of the transportation depend on the railway actors’ ability to solve a set of hard and interconnected planning problems.

15. Towards optimal railway track utilization based on societal benefit
Sammanfattning : Infrastructure managers in railway systems are striving to have as efficient track utilization as possible. There are no unanimous interpretation of efficiency in terms of track utilization, but the aim of the Swedish Transport Administration is to allocate track capacity such that societal benefit is maximized.
