1. Cost Optimization of Aircraft Structures
Sammanfattning : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. LÄS MER
2. On optimization of natural convection flows
Sammanfattning : Two different techniques are presented for enhancing the thermal performance of natural convection cooled heat sinks. The physics is described by solving the conjugate heat transfer problem with a spectral element method. The temperature distribution is computed in two sub-domains, whose solution is then conjugated.

3. Product Configuration from a Mathematical Optimization Perspective
Sammanfattning : The optimal truck configuration for a certain customer is very specific and depends on for what transport mission and in which operating environment the truck is to be used. In addition, the customers normally specify other feature requirements ranging from visual appearance to advanced driver support systems. LÄS MER
4. Approximation of topology optimization problems using sizing optimization problems
Sammanfattning : The present work is devoted to approximation techniques for singular extremal problems arising from optimal design problems in structural and fluid mechanics. The thesis consists of an introductory part and four independent papers, which however are united by the common idea of approximation and the related application areas. LÄS MER
5. Maintenance optimization for power distribution systems
Sammanfattning : Maximum asset performance is one of the major goals for electric power distribution system operators (DSOs). To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting demands from customers and regulators. LÄS MER
