Minimizing power consumption is important for mobile computers, and disks consume a signi cant portion of system-wide power. There is a large di erence in power consumption between a disk that is spinning and one that is not, so systems try to keep the disk spinning only when it must. The system must trade o between the power that can be saved by spinning the disk down quickly after each access...

Adaptive spinning-disk interferometry is capable of measuring surface profiles of a thin biolayer with subnanometer longitudinal resolution. High-speed phase modulation in the signal beam arises from the moving surface height profile on the spinning disk and is detected as a homodyne signal via dynamic two-wave mixing. A photorefractive quantum-well device performs as an adaptive mixer that com...

High speed interferometry on a spinning disk opens new opportunities for sensitive material metrology. One promising application is fast molecular screening in diagnostic medicine.

Submitted for the DFD17 Meeting of The American Physical Society Wake instabilities of flow over a spinning circular disk at angle of attack1 MARCUS LEE, TIM COLONIUS, BEVERLEY MCKEON, Caltech — A circular disk spinning about its axis of rotational symmetry is inherently robust to external disturbances due to gyroscopic moments and is therefore a promising configuration for a robust micro air v...

With the advent and subsequent popularity of portable computers, power management of system components has become an important issue. Current portable computers implement a number of power reduction techniques to achieve a longer battery life. Included among these is spinning down a disk during long periods of inactivity. In this paper, we perform a quantitative analysis of the potential costs ...

Fechner colors refer to the creation of illusory or subjective colors through an alternating pattern of black and white stimulus. Fechner reported the discovery of this illusion in an 1838 paper, and his name has been given to these illusory colors. The discovery was accidental as Fechner at the time was involved in the creation of disks to create different shades of gray [1]. From the beginnin...
