USING FLOQUET THEORY IN THE PROCEDURE FOR INVESTIGATION OF THE MOTION STABILITY OF A ROTOR SYSTEM EXHIBITING PARAMETRIC AND SELF-EXCITED VIBRATION

The computational procedure for investigation vibration stability of a flexible rotor consisting of an asymmetric shaft, one disc, and supported by ball bearings is developed in this work.Lagrange equations of the second kind were used for derivation of the motion equation.The vibration response stability of the Jeffcott-like rotor FLOOR LAMP was s

Purpose: The purpose of this study is to examine the clinical effects and results of lower-extremity surgery under ultrasound-guided nerve block; time required for nerve block, anesthesia onset time, duration of anesthesia, duration of analgesia, tolerable tourniquet time, visual analog scale (VAS) satisfaction score, and anesthetic-related complic
