An appropriate controller is designed such that this type of network can be synchronized within a finite time. By constructing a proper Lyapunov function and using the finite-time stability theory, the sufficient conditions for the network to achieve finite-time synchronization are given and the finite time is estimated. Finally, the conclusions obtained are extended to the case of homogeneous complex networks with time-varying delays and uncertain disturbance.展开更多

Firstly, the design of the toll plaza is mainly through analyzing the daily traffic flow, different charging mode of construction cost and waiting time of the United States. Secondly, exploring traffic conditions is divided into two kinds, based on the traffic flow speed-density flow model. Then, a fuzzy-BP neural network model is constructed, with capacity, cost, and safety factor as the input layers and performance as the output layer. It is concluded that this scheme will reduce the occurrence of traffic accidents, so it is desirable. Considering that the increase in unmanned vehicles will lead to an increase in safety performance, we increase the number of electronic toll stations to improve security performance and reduce the occurrence of traffic accidents.展开更多

When concerning the standards of politeness, western cultures focus more on the creation of individual's private space; while Chinese culture, as a typical collectivist culture, shows more stress on harmony and group identity. But some euphemisms and cultural rit uals show the generosity of being polite in both cultures. After this comparative study of face and politeness in two cultures, there will be a better understanding of politeness between Chinese and western communication.展开更多

In order to communicate with each other, human beings must make use of the methods of translation. Thus, it shows that translation, which is a social activity of inter-language, inter-culture and inter-community, is linked closely to culture. Meanwhile, the features of translation represent similarly in advertising translation. Generally speaking, when doing advertising translation,it can not only focus on language differences between the two sides, but also pay attention to cultural differences. Or else it would be difficult to translate satisfying advertisements. By taking examples from Chinese-English and English-Chinese, this paper compares the different aspects between Chinese and Western thinking sets, traditional ideas and values in order to reflect differences of advertising translation based on different cultures. Finally, it will sum up some strategies of inter-cultural advertising translation.展开更多

The epitaxial Ge layers were prepared in an ultrahigh vacuum chemical vapor deposition(UHV-CVD) system using low temperature Ge buffer technique. The devices were fabricated by in situ doping and using Si as passivation layer between Ge and metal, which can improve the ohmic contact and realize the high doping. The results show that the dark current of the photodetector with diameter of 24 μm is about 2.5×10^(-7) μA at the bias voltage of –1 V, and the optical responsivity is 0.1 A/W at wavelength of 1.55 μm. The 3 dB bandwidth(BW) of 4 GHz is obtained for the photodetector with diameter of 24 μm at reverse bias voltage of 1 V. The long diffusion time of minority carrier in n-type Ge and the large contact resistance in metal/Ge contacts both affect the performance of Ge photodetectors.展开更多
