With the development of industrialization and informatization, modern society is highly dependent on energy. Electric power system is fundamental for social production and daily life. Especially in urban areas, electric power network has been a key infrastructure of the lifeline, and its failure will probably paralyze the whole city. On the other hand, as population growth and urbanization, the demand for electricity is overwhelmingly increasing. Electric power network is getting larger and more complex. Meanwhile, modern electric power network is unprecedented vulnerable and modern society is faced with higher blackout risk. In order to effectively prevent blackout risk and rapidly response the blackout accident, emergency management of electric power system are responsible for preparedness, mitigation, response, and recovery of its failure. Blackout is one of the most severe accidents in electric power system failure, and is paid great attention all the time. In recent decades, many techniques have been developed for effective prevention and control of blackout. This paper analyzes the core requirements and major challenges of prevention and response of blackout. And then, some potential advanced techniques on planning, monitoring and early-warning, emergency response, etc. are introduced in view of latest research progress.

The decreasing birth rate and the rising popularity of overseas studies have combined to drag the number of candidates for college entrance exam. Besides these two reasons, the disturbance of population happened 51 years ago may cause the decrease in number of college entrance exam candidates in the future.We constructed a nonlinear regression model to analyze the impact of disturbance of population on the scale of higher education.According to our nonlinear regression model analysis,the gross enrollment rate of higher education should reach 55％ by the year 2020, and average annual increase rate of China gross college enrollment number is about 3%.Then the popularization of higher education will be realized by the year 2020,and the lack source of students could be released.

Regional Logistics and regional economy have a significant correlation. From the perspective of the logistics industry agglomeration, using the logistics industry data of 31 provinces in China, selecting three main indicators impact on the regional logistics industry based on previous research, entropy method and cluster analysis, combining to have a empirical study on overall development and characteristics of regional logistics industry in China. Entropy method gives each index weight and objectively calculated the integrated value of regional logistics industry, so we can develop the regional logistics industry integrated rank. Cluster analysis estimates the agglomeration level of regional logistics industry, and divides the 31 regions into three levels in certain similarity level certain similarity level. The regional logistics industry agglomeration effect is obvious, finally analyzed the reasons and variation of the agglomeration.

Green supply chain management (GSCM) has emerged as a key strategy and approach for enterprises obtaining international competitive power and realizing sustainable development. A lot of foreign forerunner have implemented various GSCM plans and have got successful Experience. But in terms of whole Chinese enterprises, the instance of carrying it into execution is not ideal. This paper analyses GSCM performance among Chinese and foreign enterprises. Based on the successful practice of GSCM in Chinese and foreign enterprises and the actual situation in China, this article puts forward some suggestion on spreading the idea of GSCM all over the country, provides theoretical references for the green supply chain management practice of Chinese enterprise .

In order to study the stress path in soil element of ground under moving train load and the influence of moving speed, depth and the initial stress state of soil element on the stress path, the steady-state solution of stresses in ground were obtained based on the model of Euler beam on elastic half space under one moving load. The stress path in soil element under the load moving line was analyzed. It is found that the stress state changes from pure shear to triaxial shear and back to pure shear finally in one cycle. According to the stress path curves for different moving speeds, it is found that when the moving load is high, the maximum deviator stress decreases, but the horizontal shear stress increases dramatically. The stress path curves in soil element at different depth for both a low speed and a high speed (near to the Rayleigh wave speed) were presented. It is shown that horizontal shear stress and deviator stress increase first with the depth's increasing and decreases after reaching the maximum value. The shape of stress path curves at different depth is close for a low speed but differs greatly for a high speed and the soil element at shallow depth is mainly in a tensile state. The stress paths for different initial stress states were also presented. And it is found that the initial stress state influents stress path greatly. The bigger the initial deviator stress is, the more unobvious the variation of stress state and the principal stress axes rotation are.

In this paper, the authors report the performance test results of solar home systems according to IEC 62124: Photovoltaic Stand-alone System-Design verification. The performance test evaluates solar home systems in the several aspects such as battery usable capacity, functional test, recovery test, system balance point, days of autonomy, etc.. The results show that unreasonable design is a main reason to cause failure. The other reasons are considered as battery quality problem, inappropriate setting for controller and controller quality problems.
