Sound pressure levels in emission of percussion instruments during training sessions
Archives of Acoustics, 2000 Sounds of selected percussion instruments played in individual training sessions of students-percussion players were recorded and analysed. In statistical signal analysis the "impulsiveness" in terms of Lmax-Leq and in terms of kurtosis, as an ...

Melodies of the forest: Nature as an improvisational space for shared creative embodiment
People and Nature, EarlyView.Abstract In an era marked by increasing disconnection from nature, innovative approaches to reconnect with the environment are crucial for both ecological and psychological well‐being. This paper explores how natural environments (a deciduous forest of Quebec in the present case study) can serve as an improvisational space for shared creative ...

Effects of axial impact load on the dynamics of an oilwell drillstring
Advances in Mechanical Engineering, 2019 This article studies the dynamics of oilwell drillstring under large and small axial impact loads. For the case of large impact load, the drillstring is regarded as a continuous bar under the impact load of a falling mass, and the energy conservation ...
