The vibrational behaviour of the laminated stator of an electrical machine is quite different from that of a homogeneous solid cylinder, which is often used as a model for the purpose of predicting the natural frequencies. The purpose of this paper is to present a study of the effect of laminations

## Abstract We consider graphs __G = (V,E)__ with order Ο = |__V__|, size __e__ = |__E__|, and stability number Ξ²~0~. We collect or determine upper and lower bounds on each of these parameters expressed as functions of the two others. We prove that all these bounds are sharp. Β© __1993 by John Wiley
It is well-known that the Timoshenko quotient always gives better results than the corresponding Rayleigh quotient, but its implementation is not straightforward, at least for non-uniform redundant beams. Quite recently a modified approach has been proposed [1], in which the main difficulty is overc
