A weighted evolving model of scale-free network is proposed. Our model has been inspired by the weighted network model proposed by Alain Barrat, which consider the emergences of new links according to triangle formation and strength preferential selection mechanism. Interactions more easily occur between neighbors with high-strength in our model. Numerical calculations show that our model possesses...
Formed by the stacking of solid waste from the coal industry emissions, the coal gangue dump brought about a series of ecological and environmental problems, such as the decrease of the quality of the air, surface water, groundwater and soil, ecosystem degradation, the losing of species diversity, the damage of landscape and the yield reduction of crops and so on. Therefore, the purpose of governance...
The Mine Surveying work of Eastern River Bay has been using the traditional method of manual calculation and drawing, but it can not suit to modern surveying technology any more. This paper is doing a study of drawing digitization and measurement digitization of Mine Surveying, so as to solve the problem of mine surveying digitization. We use AutoCAD as a platform, Visual Basic as the programming...
To the engineering colleges which aim at cultivating excellent applied talents, strengthening and reforming the practice teaching, cultivating the innovative spirit and practical ability of students is the focus of educational reformation. Based on the CDIO engineering education model, according to the problems of colleges teaching, this paper puts forward some new ways and methods of the colleges...
According to the characteristics of remote sensing image, we analyzed traditional problem of issue of remote sensing images, researched and explored the feasibility and necessity of issue of remote sensing image by using multi-resource data under the current network model; the article pointed out that. Assist issue of remote sensing image by the management and application of multi-source such as GIS,...
Practice teaching is an important progress of training talent in engineering colleges and it is the key point whether the aim of training higher educated talents will be realized or not. This article is based on the CDIO engineering education model "learning by doing". It makes a survey of practice teaching and analyzes the problems among Chinese engineering colleges and universities. And...
The use of advanced management ideas, scientific methods of cost management and cost management system optimization are the most urgent matter of coal enterprises. In this paper, enhancing cost competitiveness as the goal, the cost of coal enterprises was studied. In addition, the modern theory of cost management system based, the influence factors of raw coal cost was analyzed, the construction principle...
It is the most fragile ecological environment in Wangwa coal mine in south mountain areas in Ningxia. People's life and production had been seriously influenced by the coal mining subsidence area and the destroyed environment during coal mining. With the development of society, land reclamation must be imperative under the situation. Land reclamation is a complex and systematic project which need...
