Features of control high-gradient electromagnetic rotary separators are considered. Structural diagrams systems with fuzzy logic controllers the process separation given. A new block diagram a hybrid system for rotary-type separator combining classical and intelligent con-trol methods has been proposed. The example shows that can significantly increase energy efficiency in electrical technologi...

Rotary ventricular assist device (VAD) support of the cardiovascular system is susceptible to suction events due to the limited preload sensitivity of these devices. This may be of particular concern with rotary biventricular support (BiVAD) where the native, flow balancing Starling response is diminished in both ventricles. The reliability of sensor and sensorless-based control systems which a...

introduction: the aim of this in vitro study was to compare the amount of apically extruded debris after root canal preparation using rotary and reciprocating systems in severely curved root canals. methods and materials: thirty six extracted human mandibular first molars with 25-35 ° curvature in their mesiobuccal (mb) canal (according to schneider’s method) were cleaned and shaped with protap...

This paper presents an intelligent and robust guidance, navigation and control solution for a rotary-wing UAV to carry out an autonomous cargo transportation mission between two moving platforms. Different from the conventional GPS/INS-only navigation scheme, this solution also integrates sophisticated Lidar and vision systems capable of precisely locating cargo loading and unloading positions....
