11. Computational Engineering Development and Implementation of Computational Methods for Structural Analysis and Design
Sammanfattning : 'Computational engineering' (CE) is computation based on mathematical models for use in engineering design. CE can be used to study and optimise structures and processes in industry and other branches of society to utilise resources in the most effective way. Modelling, simulation, optimisation and visualisation are basic methods of CE. LÄS MER
12. Operator and Machine Models for Dynamic Simulation of Construction Machinery
Sammanfattning : VIRTUAL PROTOTYPING has been generally adopted in product development in order to minimise the traditional reliance on testing of physical prototypes. It thus constitutes a major step towards solving the conflict of actual increasing development cost and time due to increasing customer demands on one side, and the need to decrease development cost and time due to increasing competition on the other.

13. Optimisation of Railway Switches and Crossings
Sammanfattning : Methods for simulation-based optimisation of the design of railway turnouts (switches & crossings, S&C) are developed and demonstrated. Building on knowledge of dynamic wheel–rail interaction in turnouts, it is investigated how rail profile degradation can be reduced by the optimisation of geometry and component stiffness of the track superstructure.

14. Multi-Robot Motion Planning Optimisation for Handling Sheet Metal Parts
Sammanfattning : Motion planning for robot operations is concerned with path planning and trajectory generation. In multi-robot systems, i.e. with multiple robots operating simultaneously in a shared workspace, the motion planning also needs to coordinate the robots' motions to avoid collisions between them.

15. Studies of a Heavy-Duty Diesel Aftertreatment System Based on the NOX Storage and Reduction Technology
Sammanfattning : The legislative limits for NOX emissions in the exhaust gas from heavy-duty diesel engines will be decreased in the European Union from today 3.5 g/kWh (Euro IV) to 2.0 g/kWh in 2008 (Euro V). In the USA and Japan a similar trend can be seen. LÄS MER
