Spatial Homeotropic and Planar Liquid Crystal Alignment Patterning

Advanced Materials Interfaces, EarlyView.
A voltage‐assisted two‐step photoalignment methodology achieves precise micro‐patterning of alternating planar and homeotropic liquid crystal domains. Applying an AC electric field during in situ laser illumination minimizes phase retardation, reducing the required exposure dose. This cooperative mechanism enables high‐resolution spatial patterning and

Elastic feedback control

Proceedings 12th Euromicro Conference on Real-Time Systems. Euromicro RTS 2000, 2002
In many real time control applications, the task periods are typically fixed and worst case execution times are used in schedulability analysis. With the advancement of robotics, flexible visual sensing using cameras has become a popular alternative to the use of embedded sensors. Unfortunately, the execution time of visual tracking varies greatly.

Feedback control of canards

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2008
We present a control mechanism for tuning a fast-slow dynamical system undergoing a supercritical Hopf bifurcation to be in the canard regime, the tiny parameter window between small and large periodic behavior. Our control strategy uses continuous feedback control via a slow control variable to cause the system to drift on average toward canard orbits.
