We demonstrate novel molecular design for thermally activated delayed fluorescence (TADF) polymers based on a nonconjugated polyethylene backbone with through-space charge transfer effect between pendant electron donor (D) and acceptor (A) units. Different from conventional conjugated D–A through-bond effect, the architecture avoids direct conjugation D A units, enabling blue emission. Meanwhile, spatial π–π interaction physically separated units results in both small singlet–triplet energy...
A high-sensitivity demodulation method for the vibration-induced frequency shift of an optoelectronic oscillator (OEO) using acousto-optic modulator (AOM) has been proposed and experimentally demonstrated. This is achieved by separating optical carrier (OC) first-order sideband, directing them into reference sensing arms a Michelson interferometer (MI), respectively. Additionally, since system sensitivity depends on rather than oscillating frequency, vibration can be at OEO frequencies as...
While Global Navigation Satellite System (GNSS) is often used to provide global positioning if available, its intermittency and/or inaccuracy calls for fusion with other sensors. In this paper, we develop a novel GNSS-Visual-Inertial (GVINS) that fuses visual, inertial, and raw GNSS measurements within the square-root inverse sliding window filtering (SRI-SWF) framework in tightly coupled fashion, which thus termed SRI-GVINS. particular, first time, deeply fuse pseudorange, Doppler shift,...
Since it is difficult to control the magnetic intensity reduction of permanent magnet synchronous motor, there are two methods, sliding mode and self-disturbance reactance control, which make easier control. The sliding-mode has some problems, such as large jitter coarse torque. Moreover, parameters active disturbance rejection complex. A weak method motor based on proposed. Firstly, principle coordinate transformation, mathematical model PMSM established, then controller respectively...
The optical fibre endoscope with cold light is still mainstream in the market, but inherent structural characteristics of lead to its shortcomings, such as high price, inconvenient carry, and easy distortion image. micro medical electronic can receive front-end system image through miniature CCD (Charge Coupled Device) transmit display cable, which greatly solves limitations endoscope. In this paper, using ZEMAX software, an imaging 75∘ field view designed. consists four lenses, all...
In this study, a polarization-maintaining fiber Bragg grating (PM-FBG) was inscribed by femtosecond laser using line-by-line method and used as wavelength selector for wavelength-switchable erbium-doped (EDFL). The PM-FBG period 1.075 μm, the length 3200 μm. For proposed EDFL, lasing threshold 64 mW, switchable emissions with stable single dual wavelengths were realized adjusting polarization controller. experiments, different single-wavelength lasers scope values of 1563.34–1564.02 nm...
As maximum flow could be used as a significant indicator of congestion in air traffic network, the model was then proposed study. When influenced by emergencies, this model, adopting discrete time loss queuing, obtain transition probability matrix building conflicting factors. Then, with theoretical calculated.
Aiming at the problem that large-scale power flow transfer caused by node faults of cyber-physical systems, which leads to cascading faults, an improved fuzzy analytic hierarchy algorithm is proposed identify vulnerable nodes and reduce supply interruption system instability faults. Firstly, a hierarchical index constructed based on characteristics grid safety topology. Secondly, three-scale method optimal matrix are used improve calculation process traditional method, combines subjective...
