Adaptive motion planning and path following for permanent resident biofouling prevention robot operating in fish farms

This paper presents a study where the potential of achieving autonomous net cleaning operations in commercial net pens is demonstrated through numerical simulations. Specifically, we investigated solutions for coping with the challenges that occur when obstacles appear in the path of an autonomous...

Partial Discharge Activity in Rotating Machine Type II Insulation Systems as a Function of Temperature and AC Supply Frequency

The main purpose of this study was to investigate if the application of very low frequencies for PD measurements in type II generator bar insulation is relevant when compared to applying power line frequency at different test temperatures. Laboratory experiments were performed on two stator bar...
