Laser vibrometry measurements on a bowed violin are performed. A rotating disc apparatus, acting as a violin bow, is developed. It produces a continuous, long, repeatable, multi-frequency sound fro ...

Laser welded products often have to be designed and optimized for fatigue load. The most common method to characterize the fatigue strength is periodic loading of a weld for different peak loads to identify an S-N-curve. To obtain information on how

During laser welding, residual stresses are thermally induced. They can have strong impact on the fatigue behavior and fatigue life. A standardized measurement method for the fatigue crack growth rate was expanded to identify residual stress along th

The air pre-heater on the biomass boiler at Smurfit Kappa Krafliner in Piteå vibrates when run close to its maximum capability. This generates such high sound levels that the working conditions are compromised. The contracted supplier Metso Power ha

This book is a pioneering effort in critical Arctic studies. The contributions identify and investigate some of the blind spots in human development in the Arctic that research in the social sciences had yet to broach. To this end, the authors tap a
