This paper presents a design of a four phase 25% duty cycle of 400MHz DLL with calibration. To avoid the disadvantages of digital calibration method, it introduced an all-analog calibration method. Instead of DAC, CP is used in calibration loop to save power consumption and area occupying. With a 4 channel time-interleaved 6 bit flash ADC, the simulated results show that SNR is 30.8dB and 43.6dB with...
The bivariate normal mixture GARCH model is introduced in this paper, and applied to research the dynamic volatility features and the time-varying correlation structure of Shanghai Composite Index and Shenzhen Component Index in Chinese stock markets. Empirical results demonstrate that the bivariate normal mixture GARCH model outperforms other competing GARCH models, in terms of explaining the properties...
Bacillus globisporus A95, a novel strain isolated from tea rhizosphere soil, showed broad-spectrum antifungal activity. Statistical optimization of the medium was applied to enhance the antifungal metabolites production. The Plackett-Burman Design revealed that soybean meal and CaCO3 significantly affected the active substances production. A 24-Central composite design was used for response surface...
The Voronoi diagram is the one of most fundamentals in computation geometry. The coverage control, especially the barrier coverage, will benefit from this diagram. Using the Voronoi diagram, the coverage holes can be detected in short time. In the lax demands which only include the influence of two neighbor sensors, the minimal exposure track based on the Voronoi can approach the optimal. But, because...
Passport is a new secure and adoptable source address validation technique, which has attracted fully attention. In this article, we research into the efficiency of Passport. First of all, we build a mathematical model to describe Passportpsilas function, then propose an evaluating indexes, at last we use Brite generate a Power-Law network topology and design correlative algorithm to quantitative...
