The contact stiffness of the spindle/tool holder is essential for the cutting stability of the spindle system because the elastic connection of the spindle/tool holder interface determines the dynamic characteristics of the spindle system. To predict the

Fractals in the Quantum Theory of Spacetime
International Journal of Modern Physics A, 1989We review in this paper the first results obtained in an attempt at understanding quantum space-time based on a new extension of the principle of relativity and on the geometrical concept of fractals. We present methods for dealing with the nondifferentiability and the infinities of fractals, as a first step towards the definition and intrinsic ...

AbstractTop-down hierarchies are typically characterised by command-and-control systems of authority that often create harmful stress and internal competition for advancement within organisations. The pervading perception is of ‘limited room at the top’, where positions of authority become scarce resources.
