An algorithm based on correlation analysis was adopted to estimate the probability of presence damage in aluminum plates using Lamb wave signals from an active sensor network. Both finite element and experimental evaluations were presented. The Shannon entropy optimization criterion applied calibrate optimal mother wavelet most appropriate continuous transform scale for signal processing. coefficients individual sensing paths between present state (with damage) reference (without calculated,...
Advanced lithography requires highly sensitive photoresists to improve the lithographic efficiency, and it is critical, yet challenging, develop high-sensitivity imaging strategies. Here, we report a novel strategy for ultra-high sensitivity using hexafluoroisopropanol (HFIP)-containing fluoropolymer photoresists. The incorporation of HFIP, with its strong electrophilic property electron-withdrawing effect fluorine atoms, significantly increases acidity photoresist after exposure, enabling...
The inlet noise of auxiliary power unit (APU) for the civil aircraft, as a major source apron noise, has been widely discussed and concerned. Given its high-frequency dominant characteristics, this paper distinguishes itself from traditional uniform honeycomb core depth liners by optimizing four types acoustic liners: single-degree-of-freedom (SDOF) liners, double-degree-of-freedom (DDOF) parallel SDOF DDOF within their respective design spaces. goal is to achieve broader absorption...
A probabilistic damage diagnostic algorithm based on correlation analysis was investigated to locate single or multiple damage. To highlight the changes in signals corresponding presence of damage, digital fingerprints (DDFs) were extracted from captured Lamb wave signals. The validated through experimental studies where dual artificially introduced notches an aluminum plate successfully located using constructed images probability Damage identification either their DDFs agreed well with...
The paper presents a new model for crowd-sensing applications, where humans are used as the sensing sources to report information regarding physical world. In contrast previous work on topic, we consider in question polarized. Such might be case, example, political disputes and situations involving different communities with largely dissimilar beliefs that color their interpretation reporting of world events. Reconstructing accurate ground truth is more complicated when describes an...
Recently, electrodialysis technology has received widespread attention in the fields of water resource utilization. The core is structure and performance ion exchange membrane. This study uses single variable method to investigate effects energy consumption, current efficiency, other parameters homogeneous heterogeneous membranes, then by chemical analysis scientific numerical determine best operating for process different membranes. experimental results show that efficiencies membrane can...
Travelling wave fault location approach for overhead transmission line is widely applied in actual power grid, which has better accuracy comparing with conventional frequency data based method. However, travelling highly related to the distortion phenomenon of propagation velocity, includes two parts: (i) caused by reflection and refraction phenomena transformer substation (ii) attenuation distributed resistance line. Therefore, aiming improve accuracy, paper contributes aspects: complete...
With the sinusoidal charging scheme, large dc link capacitance of on-board battery charger can be reduced significantly. However, variable current together with wide voltage range imposes serious challenge to maintain high efficiency throughout whole procedure. This paper proposes a LLC dc-dc transformer (DCX) solution improve over full range. Furthermore, on basis topology, power decoupling control scheme is proposed realize front-end PFC and output at side. A 1 kW prototype was built...
Traditional travelling wave (TW) protection is affected by a series of factors such as fault initial angles, grounding resistances, locations and bus structures. Especially, limited bandwidth traditional transformers also restricts the application TW protection. Hence, to improve reliability sensibility method, study designs an ultra-high-speed directional method based on output electronic (ET). First, establishes models ET including Rogowski coil-based current transformer capacitance...
As known, voltage source converter‐based high‐voltage direct current (VSC‐HVDC) transmission system is widely utilised in actual power grid. It suitable for asynchronous networking, such as the connection of offshore wind farm to main Generally, primary protection principle, travelling wave (TW) adopted based on technologies ABB and SIEMENS, which only transient quantity principle instead true TW has no fault direction discrimination ability. Besides, because large capacitances applied...
