A novel parallel structured fiber-optic Fabry-Perot interferometer (FPI) based on Vernier-effect is theoretically proposed and experimentally demonstrated for ultrasensitive strain measurement. This sensor consists of open-cavity closed-cavity FPI, both which are connected in via a 3 dB coupler. The implemented sensing, while the reference. Experimental results show that FPI can provide an ultra-high sensitivity -43.2 pm/με, 4.6 times higher than single FPI. Furthermore, simple fabrication,...

Air-breathing proton exchange membrane fuel cells (PEMFCs) show enormous potential in small and portable applications because of their brief construction time without the need for gas supply, humidification cooling devices. In current work, a 3D multiphase model single air-breathing PEMFCs is developed by considering contact resistance between diffusion layer bipolar plate anisotropic thermal conduction electric conductive through-plane in-plane directions. The presents good grid...
We propose and analyze an efficient scheme for realizing high-sensitive mass sensor in a quadratically coupled optomechanical system via nonlinear second-order sideband process.

Moreover, excellent features...
Existing contrast enhancement techniques, such as histogram equalization (HE) and optimal contrast-tone mapping (OCTM), construct a pixel function based on probability. However, they often allocate large dynamic range to smooth areas, thus preventing the allocation of resources in some regions that people are more interested in. To deal with this problem, we propose optimized perceptual tone (OPTM), which performs images considering human visual attention. First, saliency attention...
Aeroengine, served by gas turbine, is a highly sophisticated system. It hard task to analyze the location and cause of gas-path faults computational-fluid-dynamics software or thermodynamic functions.
