1. Marine Propeller Optimisation - Strategy and Algorithm Development
Sammanfattning : Recent trends in the shipping industry, e.g., expanded routing in ecologically sensitive areas and emission regulations, have sharpened the perception of efficient propeller designs. Currently, propeller efficiency, estimated fuel consumption and, more often, propeller-radiated noise are parameters that steer the business Zeitgeist. LÄS MER
2. Engineering Quality Feelings : Applications in products, service environments and work systems
Sammanfattning : Contemporary quality issues in product design are moving from materialistic to emotional user fulfillment; comprehensive research is needed to examine quality product feelings. This research is directed toward a deeper understanding of user and customer quality feelings for different product types, including services. LÄS MER
3. Development of voyage optimization algorithms for sustainable shipping and their impact to ship design
Sammanfattning : The environmental impacts from shipping and the societal challenges of human and property losses caused by ship accidents are pressuring the shipping industry to improve its energy efficiency and enhance ship safety. Voyage optimization is such an effective measure that has been widely adopted in today’s shipping market. LÄS MER
4. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance
Sammanfattning : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. LÄS MER
5. Inverse and optimization problems in electromagnetics -- a finite-element method perspective
Sammanfattning : In this thesis, a selection of inverse and optimization problems are studied where the finite element method (FEM) serves as a comprehensive tool to solve electromagnetic field problems that lack an analytic solution. The inverse problems are typically formulated in terms of an optimization problem where the misfit between a measurement and the corresponding result of a computational model is minimized. LÄS MER
