Efficiency of stump chipping of soft and hard broadleaves [PDF]
Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2018 Stump removal is a regular measure of terrain preparation during the establishment of poplar plantations. It is implemented in order to increase the efficiency of implementation of regular silvicultural measures, but also the efficiency of comprehensive ...

Diffraction assisted rough ground effect. [PDF]
The Journal of the Acoustical Society of America, 2010 Ground effect results from the interference between sound traveling directly from a point source to a receiver and that reflected coherently from the ground. The frequencies associated with first and subsequent order destructive interference in excess attenuation spectra are determined by the source-receiver geometry and the ground impedance. Typically

On the origin of the ground effect
International Journal of Mechanical Engineering Education, 2023 The ground effect is well known to pilots and aerodynamicists alike. However, the current explanations found in undergraduate (and pilot-focused) textbooks can be inconsistent, often attributing the phenomena to the interaction between tip vortices at the ground.

A Site Amplification Model for Crustal Earthquakes
Geosciences, 2018 A global dataset which is composed of more than 20,000 records is used to develop an empirical nonlinear soil amplification model for crustal earthquakes. The model also includes the deep soil effect. The soil nonlinearity is formulated in terms of input
