Dr Limin Yang

Obtained his degree on May 26 after successfully giving his trial lecture entitled "Design Principles for Floating Wind Turbines". 

His thesis is entitled: "Stochastic Dynamic System Analysis of Wave Energy Converter with Hydraulic Power Take-Off, with Particular Reference to Wear Damage Analysis". 

Limin Yang is the first PhD candidate at CeSOS to give his trial lecture and defence live via webcamera to the committee. Several flights were cancelled due to the eruption of the volcano Grimsvotn on Iceland, so committee members Professor Antonio Falcao (Lisbon) and Dr. Anthony Lewis (Cork) were unable to come to Trondheim. The event was mentioned in the local newspaper Adressa.
