A novel fiber structure, coreless side-polished (CSPF) that is wrapped by polydimethylsiloxane (PDMS), demonstrated to be highly sensitive temperature because of the high refractive index sensitivity CSPF and large thermal optic coefficient PDMS. Our numerical experimental results show several dips in transmitted spectra PDMSW-CSPF originated from multimode interference (MMI) will blueshift with increase temperature. Furthermore, for such a PDMSW-CSPF, we investigate its sensing...
This study explores the sunlight resistance of polysulfonamide (PSA) fabrics dyed with dispersed dyes through a high-temperature, high-pressure carrier dyeing method. PSA fibers, valued for their thermal stability and chemical resistance, exhibit low light fastness under UV exposure. The absorption, color fastness, degradation Disperse Red 60 (DR), Blue 56 (DB), Violet 26 (DV) were analyzed. UV-Vis spectroscopy showed that PSA/DB had highest absorption photostability, followed by PSA/DV...
Cities are typical dynamic complex systems that connect people and facilitate interactions. Revealing general collective patterns behind spatiotemporal interactions between residents is crucial for various urban studies, of which we still lacking a comprehensive understanding. Massive cellphone data enable us to construct interaction networks based on co-occurrence individuals. The rank-size distributions population locations in all unit time windows stable, although almost constantly moving...
Magnetic levitation control technology plays a significant role in maglev trains. Designing controller for the system is challenging due to strong nonlinearity, open-loop instability, and need fast response security. In this study, we propose Disturbance-Observe-based tube Model Predictive Levitation Control (DO-TMPLC) scheme combined with feedback linearization strategy system. The proposed incorporates state constraints input constraints, i.e., air gap, vertical velocity, current applied...
A novel hierarchical control framework combining computed-torque-like (CTLC) with disturbance-observer-based event-triggered robust model predictive (DO-ET-RMPC) is proposed for the trajectory tracking of robotic manipulators bounded disturbances and state input constraints. The CTLC approach first used to cancel exact nonlinear dynamics original error system obtain a set decoupling linear subsystems, thus reducing optimization complexity (MPC). composite DO-ET-RMPC scheme then developed...
Summary Contamination of peanut oil is a great concern in the industry. FTIR spectroscopy combined with chemometrics could develop rapid and nondestructive method to screen aflatoxin‐contaminated oil. Aflatoxin B1 ( AFB 1)‐ aflatoxin AFT )‐positive oils were screened by mid‐ IR MIR ) classification models established novel multivariate decision tree MDT method. Two discriminant functions developed fingerprint region based on absorbance ratio moving window Fisher discrimination analysis...
This article proposes a disturbance-observer-based self-triggered distributed model predictive control (DSDMPC) algorithm with an adaptive prediction horizon mechanism for discrete-time nonlinear multiagent systems (MASs) disturbances and system constraints. First, decentralized disturbance observers are designed. They combined space decomposition technique to concurrently estimate eliminate the matched of MASs. Robust tightened state input constraints generated based on estimation...
(CuStBu)4(PMe3)2 is synthesized as the first single-source precursor for monoclinic chalcocite (α-Cu2S). Phase-pure films of copper-rich were grown by aerosol-assisted spray pyrolysis. The chemically pure exhibit a very strong out-of-plane orientation on glass result their composition large micrometer-sized plates.
Based on the principle that chlorophyll’s photodegradation occurs in presence of oxygen, high-oxygen-barrier polyvinyl alcohol (PVA) films comprising chlorophyll are prepared without by a facile procedure. The photostability characterized absorption spectra. result shows can keep photostable at least for six months whereas ethanol is less than one day. maxima chlorophyll/PVA red band, which 668nm due to and consist with (666 nm), shift blue after sunlight treatment. extent increases time...
In this paper, a novel method used for Fabry-Perot cavity length's demodulation in high-speed and large scope measurement was proposed. Principle of the is based on uniqueness intensity multiple wavelengths vibration. This technique offers flexibility selecting incident wave length enhances length, compared with that popular triple demodulation. experiment, multi-wavelength demonstrated varying from 110um to 115um strain resolution higher than 0.1um.
