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
Sammanfattning : A recent trend in software engineering is to delay design decisions. One motivation is that requirements or properties of the application and environment are not known until later in the design and development process. This continues to hold for design decisions in a high-performance context where e.g. LÄS MER
Sammanfattning : The ground source heat pumps (GSHPs) of customers connected to the district heating and cooling (DHC) network can benefit both the customer and the energy company. However, operating the GSHP to minimize the cost of providing heating and cooling to the customer while ensuring the long-term stability of the ground temperature is a challenge. LÄS MER
Sammanfattning : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. LÄS MER
Sammanfattning : As the design of buses is constantly improving, passengers are becoming more fastidious and the demand for a more comfortable travelling environment is constantly increasing. The main objective of this thesis is to contribute to the understanding of how the design of buses affects the ride comfort characteristics. LÄS MER
