This paper discusses a dynamic model designed for Helicobacter pylori and antibiotic response. Respectively, with the integer order and fractional order of the equivalent circuit model to describe time-kill curve for different concentrations of antibiotic and Helicobacter pylori, where the parameters and variables in the model are introduced from external data. The fitting effect of the two is compared,...
The Inductor-Disconnected-Discharge (IDD) arc model researched is foundation of the evaluation for the intrinsically safe performance. The IDD characteristics were studied, based on the IEC safety spark test apparatus. The discharge process was divided into three stages, i.e. arcing, arc discharge and glow discharge stage. The discharge resistances in each discharge stage were deeply analyzed. It...
Battery models play important roles in battery manufacturing, design, safe operation, and many of its applications, such as in providing power sources of electric vehicles due to the high energy density, long life, and high cell voltage. Unlike the detection of impedance spectrum in a short linear interval, the I-V characteristic of lithium-ion batteries presents strongly nonlinearity such as the...
The average-value model (AVM) of the modular multilevel converters (MMCs) is the simplified one for the average response of switching devices, converters and control. The effect of sub-module capacitor voltage ripple on the MMC dynamic behavior is explored and an accurate average-value model of MMCs is established. Based on the proposed AVM, the equivalent impedances of the DC and AC sides in the...
With rapid development of communication technology, the signal integrity is impacting the system performance much more than before. So either in the IC design or in the system design, it is very important to investigate negative timing analysis and its mathematical modeling in the high speed integrated circuit. In the paper, we introduce the origin of the negative timing script in the deep sub-micrometer...
