27. Wind Turbine Drive Train System Dynamics ; Multibody Dynamic Modelling and Global Sensitivity Analysis
Abstract : To facilitate the design and production of highly efficient and reliable wind turbine drive trains, this thesis deals with the mathematical modelling and analysis of drive train system dynamics. The drive train is considered as the subsystem of the wind turbine that transfers mechanical power from the rotor hub to the generator, and thereby plays an important role in the system dynamics and the efficiency of wind turbine operation.

28. Motor control in zebrafish : excitatory drive and developmental changes
Abstract : An essential characteristic of human and animal life is the ability to move from one place to another, in order to survive in a complex environment. All the different forms of locomotion, like walking, swimming, crawling and flying, have one common feature: rhythmic and alternating movements of the body. READ MORE

29. Ion cyclotron resonance heating and current drive in tokamaks
Abstract : In this thesis numerical studies, performed with theMonte-Carlo code FIDO of the evolution of the resonant-iondistribution function in the presence of ion cyclotronresonance heating (ICRH) in toroidal geometry are presented. Inparticular it is pointed out how the absorption of toroidalmomentum from a wave field with finite parallel wave numberscauses spatial drift and diffusion, which together with thefinite orbit widths of the tail ions is shown to have a largeeffect on the temperature profile of the resonant ion speciesand also to cause losses of high-energy ions to the wall.

30. Electric Machine Control for Energy Efficient Electric Drive Systems
Abstract : Over the past decade, electric vehicles has increasingly become an area of attention for both academia and industry, much due to challenges such as emissions legislation and the environmental impact of the transportation sector. The absence of the broadband noise from the internal combustion engine brings new acoustic challenges for electric propulsion applications. READ MORE
