Inductive Power Transfer (IPT) system makes use of high frequency inverter and resonant compensation network to transmit power without any electric contact, which makes power transfer more convenient and safer. IPT system is a high order and nonlinear system, modeling and analysis of such a system is complicated because its state variables like inductor currents and capacitor voltages present rapid...
With the research method of system dynamics tools, the paper analyses the internal and external factors influencing the sustainable development of the Chinese athletic talent reserve, design the system dynamics equation by using the ratio of athlete population as the core variable and drawing the chart of cause and effect and construct the system dynamics model. The paper also uses the Vensim PLE...
The one-dimensional consolidation of soft soil induced by water head difference between the top and the bottom of the soil layer was studied. One-dimensional consolidation equation expressed by water head under arbitrary datum plane was derived, and the general solution was obtained for arbitrary decline model of water table. Furthermore, for two simple models which are linear decline model and instant...
Focus on the selects 4 pieces of women seamless underwear with the character of the same style, yarn and weaving mode and different size, this paper, through the young woman trying on the samples, measures the pressure of each part's test pints and gives the subjective assessment of comfort to the parts. With the method of fuzzy math to preprocess test datum, regression analysis is used to process...
In order to capture the inner-surface cloud of pipe figure components with different material rapidly and efficiently, a new cloud capturing system based on computer vision for inner-surface of pipe figure components was designed. Firstly, the IIRDL (Integrated Inner-reflection Ringy Discrete Laser-spot) method was proposed, which combined the merits of the LSS (Laser Single-spot Scanning) method,...
