1. Quantum Coherence and Quantum-Vacuum Effects in Some Artificial Electromagnetic Media
Sammanfattning : The author of this thesis concentrates his attention on quantum optical properties of some artificial electromagnetic media, such as quantum coherent atomic vapors (various multilevel electromagnetically induced transparency vapors) and negative refractive index materials, and suggests some possible ways to manipulate wave propagations inside the artificial electromagnetic materials based on quantum coherence and quantum vacuum effects. In Chapters 1 and 2, the author reviews the previous papers on quantum coherence as well as the relevant work such as electromagnetically induced transparency (EIT), atomic population trapping and their various applications.

2. Strongly Coupled Performance Prediction for Sailing Yachts based on CFD
Sammanfattning : Quantifying performance of sailing yachts can be done in many different ways. Historically the most common way is a static approach where a steady state solution is obtained by solving equilibrium equations in 3 or 4 degrees of freedom. More recently, dynamic methods have appeared. In this thesis a method of the latter kind in proposed. LÄS MER
3. Dynamic effects on yacht sails and rudders
Sammanfattning : In search of increased performance, modern sailing vessels are becoming more and more complex, introducing additional challenges in the design process. The dynamic behaviour of the vessel is of great importance to safe and efficient operation and thus needs to be accounted for when evaluating the performance. LÄS MER
4. Modelling Sea Surface Dynamics Using Crossing Distributions
Sammanfattning : The thesis deals mainly with modelling sea surface dynamics. We consider two different scales. LÄS MER
5. Modeling and Control of EGR on Marine Two-Stroke Diesel Engines
Sammanfattning : The international marine shipping industry is responsible for the transport of around 90% of the total world trade. Low-speed two-stroke diesel engines usually propel the largest trading ships. This engine type choice is mainly motivated by its high fuel efficiency and the capacity to burn cheap low-quality fuels.
