We normalize the data we need at the beginning.Then we use analysis hierarchy process to evaluate a college by proposing a comprehensive index which is composed of 4 big factors[1].The comprehensive index is calculated by the accumulation of these indexes according to different weights,and these weights...

ZnWO4/CdS composite photocatalyst had been successfully synthesized by a facile hydrothermal process. The catalysts were characterized by powder X-ray diffraction (XRD), transmission electron microcopy (TEM), and UV-vis diffuse reflectance spectrum (DRS). The results showed that the as-obtained samples...

Aiming at the nonlinear characteristics of the fault vibration signal of the emulsifier, a feature extraction method based on Empirical Mode Decomposition (EMD) and Sample Entropy (SampEn) is proposed.In this method, the original vibration signal is decomposed into a finite number of intrinsic mode functions...

Water scarcity, a problem worldwide, is payed more and more attention to. In this paper, we mainly make an intervention plan taking all the drivers of water scarcity into account. We choose to analyze the water situation of Beijing. In consideration of all the factors caused water scarcity, we use fuzzy...

In this paper, a model is developed to measure the ability of water supply in a region, based on the dynamic nature of the factors that affect both supply and demand. We pick China, a water-strapped country, to begin our analysis. For water demand, we assume the water demand can be approximately thought...

This paper introduces the composition of the anti-lock braking system and the braking principle of the wheel and the whole vehicle. It lists the control method and work process of the wheel and the vehicle. The processing method of the car motion parameter is also discussed. In addition, combining the...

With the development of modern society, people's aesthetic ideas from the original retro fashion into the United States, the prevalence of cheongsam in the Republic of filling out the characteristics of Chinese female beauty, cheongsam Chinese culture is unique, it demonstrated the Chinese women's curves,...

Because some signals have W-disjoint orthogonality, this paper proposes a signal direction of arrival estimation method in underdetermined conditions. This method is mainly based on the principle that signals of different directions lead to different time delay between the sensors, construct a potential...

The modeling and simulation of sea clutter is an important part of environmental simulation in radar target simulation. Sea clutter data got from simulation is good or not is the key to the optimal design of radar and radar signal processing. The presence of sea clutter will influence radar target detection...
