Close-to-nature forestry is a viable option to manage forests that are resilient the challenges presented by climate change. The new silvicultural schemes necessitate adapting operational side, posing productivity and environmental effects of harvesting machinery technologies. This study focused on analysing disturbance residual stands forest soils in were being restructured into multistorey, c...

Rolling contact fatigue tests on 100Cr6 steel were carried out with a ballon-rod tester. Microstructural damage was manifested by gradual hardness changes under the subsurface, and microcracks formed adjacent to inclusions; both being evidence of plastic deformation. The hardness increase appears to be due to the development of residual stress, while the microcracks form as a result of the conc...

For mechanical system structural health monitoring, a new residual generation method is proposed in this paper, inspired by recent result on subspace identification. It improves statistical properties of the existing residual, which has been naturally derived from standard identification method. Replacing monitored state-space model Kalman filter one-step ahead predictor key element improvement...
