The unbalanced magnetic pull (UMP) is one of the main vibration sources motorized spindle. A calculation model UMP in a synchronous spindle considering magneto-thermal coupling proposed this paper. finite element analysis models electromagnetic field and temperature are first established. Then two-way method effect variations on material properties motor proposed. An experiment conducted to ver...

background: spindle trees (euonymus japonica thunb.) growing in an industrial complex area containing pollutants is chronically injured thus need to build up their resistance. antioxidant enzymes and cell membrane stability have been widely used to differentiate stress tolerance. materials and methods: leaves of spindle trees from a clean control area (kijang) and an industrial area (onsan) whe...

the suppression of the regenerative chatter phenomenon in turning process via the variation of the frequency and amplitude of the spindle motor excitation is carried out in this research. a programmable inverter is employed for variable periodic excitation of the spindle motor. a set of turning experiments is designed and performed on a number of conical work pieces both in constant spindle spe...

BACKGROUND During cell division, chromosomes must clear the path of the cleavage furrow before the onset of cytokinesis. The abscission checkpoint in mammalian cells stabilizes the cleavage furrow in the presence of a chromatin obstruction. This provides time to resolve the obstruction before the cleavage furrow regresses or breaks the chromosomes, preventing aneuploidy or DNA damage. Two unans...

This paper demonstrates the application of two methods of separating spindle error motion from artifact roundness on a spindle with less than five nanometers radial error. Two error separation methods, reversal and multiprobe, were each applied to data taken on two different test stands allowing direct comparison of the four combinations of hardware and separation algorithm. Because the theory ...
