A tool adaptor with built-in active vibration damping device to dynamically stabilize the turning process is presented in this paper. It can be used in standard CNC-lathes and allows the usage of off-the-shelf tool heads. The vibration compensation system is based on a multilayer piezoactuator that is in collocation with a piezoelectric force sensor. An analogue controller based on the integral...

This paper addresses an on-off adaptive damping isolation, in which the can be frequency dependent. The comparison with passive isolation is illustrated by trade off performance curve, shown relation between displacement and force transmissibility. control based on dampings a switching frequency. analytical optimization of law obtained. optimized showed remarkable improvement comparing one. At ...

in vitro and greenhouse studies were conducted to investigate the possibility of an interaction between two systemic insecticides of: thiodicarb (larvin df 80) and imidacloprid (guacho sw 70), and seedling disease organisms of: rhizoctonia solani, fusarium moniliforme and pythium ultimum. when in vitro concentrations of imidacloprid and thiodicarb were applied, a fungistatic activity occurred. ...

Damping of collective rotational motion in A ∼ 190 and A ∼ 150 superdeformed nuclei is studied by means of the cranked shell model with two-body residual force. Numerical calculations predict that in a typical A ∼ 190 superdeformed nucleus, Hg, the rotational damping width is significantly small, Γrot ∼ 30 keV, and that the number of superdeformed bands in the off-yrast region amounts up to 150...
