Fast sliding-mode seek control of hard disk servos

Microsystem Technologies, 2003
A nonlinear controller is presented for both seeking control and following control in hard disk servos. Usually, a switching mechanism is used for mode transit from seeking to following. As a result, the seeking time and settling time are lengthened very much, especially for short seeks.

Modes of Extrapolation: The Formulas of Hard SF

Science Fiction Studies, 1993
Like other popular artforms, science fiction is “formulaic,” but its formulas, ranging from myth to mathematics, cannot be determined simply by era, setting, type of plot, or conventional values. As a form of fantasy, SF uses exaggeration, inversion, and extension as points of relevance to readers focused on the here and now.

Influence of diffraction on hard-aperture Kerr-lens mode locking

Optics Letters, 1995
It is demonstrated that with rigorous inclusion of diffraction on an intracavity hard aperture the values of the nonlinear differential loss coefficient Gamma (which characterizes the efficiency of Kerr-lens mode locking) are several times higher than in the commonly used simplified approach in which diffraction effects are neglected.

Deviatoric and hydrostatic mode interaction in hard and soft tissue

Journal of Biomechanics, 1990
It has been established that many hard and soft tissues have anisotropic material symmetry. It is noted here that the deviatoric and hydrostatic modes interact with each other in a general anisotropic elastic material. In the special case of isotropic, linear elastic, materials these modes are non-interactive.
