Heat Transfer of Water Flow Boiling in Nanostructured Open Microchannels
Energies, 2023 In recent years, the open microchannel has drawn increasing interest, but severe local dryout limited the heat transfer capability of flow boiling. It was anticipated that nanostructures with exceptional capillary wicking abilities would overcome this ...

Phase-controlled nonlinear interferometry [PDF]
Applied Physics B Photophysics and Laser Chemistry, 1989 We have studied the influence of (relative) phases between fundamental and generated harmonic in a variety of nonlinear optical experiments. The concomitant large coherence length and the various methods of phase-control known from linear optics facilitate amplitude superposition and the generation of novel interference patterns, which may be used to ...

Phase controlled SERS enhancement [PDF]
Scientific Reports, 2019 AbstractSurface-enhanced Raman spectroscopy (SERS) has attracted increasing interest for chemical and biochemical sensing. Several studies have shown that SERS intensities are significantly increased when an optical interference substrate composed of a dielectric spacer and a reflector is used as a supporting substrate.

Phase correction for Learning Feedforward Control [PDF]
, 2003 Intelligent mechatronics makes it possible to compensate for effects that are difficult to compensate for by construction or by linear control, by including some intelligence into the system. The compensation of state dependent effects, e.g.

Self-Reproducing Hidden Attractors in Fractional-Order Chaotic Systems Using Affine Transformations
IEEE Open Journal of Circuits and Systems, 2020 This article proposes a unified approach for hidden attractors control in fractional-order chaotic systems. Hidden attractors have small basins of attractions and are very sensitive to initial conditions and parameters.
