This paper proposes a global sensitivity analysis method of wireless power transfer (WPT) system in domino structure. The characteristics to capacitor deviations is studied identify sensitive parameters that cause significant uncertainty the output. effect on output current, efficiency, and factor comprehensively investigated. Interactions between capacitors are considered, main index S total ST calculated by Sobol' method. Its results indicate factor, efficiency slightly affected deviation...
Polydimethylsiloxane/multi-walled carbon nanotube (PDMS/MWCNT) composite had high photoacoustic transduction efficiency owing to its light absorption coefficient and low interfacial thermal resistance. The expansion ability of PDMS/MWCNT nanocomposite films have significant positive effects when it is used as a laser ultrasonic transducer. We introduce an ultrasonic-assisted forced impregnation method for the preparation films. PDMS was matrix phase, MWCNTs were nano-supporting framework....
ABSTRACT This paper proposed a segment‐compensated printed circuit board (PCB) coil for multirelay wireless power transfer (WPT) system. The PCB is designed with variable width to improve the system efficiency, and segmented compensation method applied avoid high voltage stress on resonant capacitors in case of WPT low load resistance operating at constant frequency. are integrated into coil, so as constitute compact coupler used optimization procedure also provided. quality factor can be...
Finite difference method (FDM) is used to numerical stimulation analysis for chloride diffusion in concrete. By computing, comparison of content profile different concrete members with sectional shapes made. Calculation and show the prolife rectangular circular section has obvious difference. If side length equal diameter section, as well material property environment, higher than that section. In calculation example, at depth reinforcement about 50-60% This tendency more remarkable less...
With the sharp change of management environment in China Bank industry, it has very important significance to objectively appraise and analysis. This paper evaluated analyzed competence Chinese commercial bank by applying factor analysis method arranges them an order adopting confirm weight each index, which analyzes competitiveness state banks our country detail. Finally, accordingly puts forward a series measures strategies on basis combining with actual conditions for strengthening...
The production process of modern enterprises gives out a huge amount data with increasing potential security risks. As new technology and way thinking, big has the most basic application in safety, which is to analyze laws safety from generated by massive activities, then eliminate hazards for effectively curbing occurrence accidents. This paper analyzes relationship between operational risk solves theoretical problems how apply based on relevant theories characteristics data. On this basis,...
Deformation of helical buckling appears on tubing string under axial compressive loads, and it may even make the fail when loads are excessively large. To clear stress distribution variation string, formulas equivalent stresses inside outside deduced based spring theory fourth strength theory. From analysis, we can see that VonMises increase with clearance casing, 22.44 percent 45.9 respectively for form 29.1mm to 39.69mm. The proposed method used makes up insufficient traditional tubular...
Structure ontology characteristic of blogosphere is one the hot topics in social computing. It has an important research value for blog dissemination, community discovery, mining etc. From empirical on a number blogospheres real world, we find that characterized by local centralized large-scale complex network, whose closely related to channel, and composed multiple discrete small networks. The previous methods using structure reductionism or functional cannot fully explain evolution...
The buckling deformation and stress distribution of the tubing nearby packer would be seriously influenced by constraints. This paper focused on Strength analysis transitional segment. method to calculate equivalent segment were derived considering boundary continuity condition, adopting fourth-order nonlinear ordinary differential equations helical strength method. study makes up for weakness traditional in vertical well, improves pertinence accuracy tubing. results show that with axial...
Since there are few methods to evaluate the qualitative index in dam safety monitoring and evaluation system is imperfect, this paper a new quantitative comprehensive method for explored with introduction of interval marking, Set-Valued Statistics, grey theory Jousselme distance function. Firstly, marking Statistics used obtain value; then class value quantified evidence vector obtained through theory; next weights all indices function; finally influence on determined by using weights. The...
In this paper, a system of wireless energy transfer based on resonant coupling is established and an equivalent circuit model analyzed. Some key concepts such as frequency splitting the maximum operating distance are validated through experiments. The efficiency over 60% when within 10cm for two-resonator system. between transmitter receiver can be enhanced, improved by relay resonators.
High-power and large-depth are big problems which restrict the development of electromagnetic detection technology. One solutions is to provide numerous frequencies power supply can expand range frequency. In this paper, a new control strategy inverter based on FPGA proposed. It make emit multiple deepen depth. This research has positive significance geological survey in our county.
