Optical position clamping with predictive control
Heikki Ojala, Anders Korsback, Anders E. Wallin, and Edward Haeggstrom
We increase the effective stiffness of optical tweezers by position clamping a polystyrene bead with a predictive feedback control algorithm. This algorithm mitigates the effect of feedback loop delay. Hence, higher gain than with proportional control can be employed, which results in higher effecti ... [Appl. Phys.

Takashi Hasuike, Hideki Katagiri, and Hiroaki Ishii
This paper considers a bi-criteria general 01 random fuzzy programming problem based on the degree of necessity which include some previous 01 stochastic and fuzzy programming problems. The proposal problem is not well-defined due to including randomness and fuzziness. Therefore, by introducing chan ... [AIP Conf. Proc. 1174, 69 (2009)] published Wed Oct 14, 2009.

Spatial Stimulus-response (S-R) Compatibility Effect of Visual Signals and Hand Controls in Transverse and Longitudinal Dimensions
Ken W. L. Chan and Alan H. S. Chan
Past research studies on spatial compatibility have shown that when the positions of stimulus and response could be concurrently interpreted in terms of horizontal (right-left) and vertical (top-bottom) dimensions, the use of the former one was found to be much stronger than the latter one in compat ...
