In accordance with the variation, this paper divides the indexes for sustainable development of water resources into five categories. And the appropriate forecasting methods to predict the direction of the data in future is given, to lay the foundation for further study of changes in sustainable development...

Proposing solution to clean water shortage is of great importance to all citizens of the world. In this paper, we do a research on water conditions of Ukraine, which indicates that a perfect intervention plan for solving the problem of water shortage is needed. We provide the solution on the two aspects,...

The water conservancy and hydropower engineering is built to make full use of the amazing power of water, while there exist variety kinds of risks in the process of the system building and operation. Based on the anal-ysis of the definition and structure of water conservancy and hydropower engineering,...

Aiming at the big difficulty in predicting the inner front narrow channel sand body, by the example of P group reservoir of the G oilfield, we have discussed the application of post-stack geostatistics inversion in the prediction of narrow channel sand body. During the process of application, combing...

Because of over fishing and environmental pollution, global fisheries resources is declined shapely, many natu-ral fisheries were severely damaged. At present, marine ranching construction has been developed rapidly in the coastal countries, and has obtained the good effect. Artificial fish reef is the...

With the developing of shale gas industry, in order to predict rock drillability in drilling time, we should set up the rock drillability profile, which has significant meaning. The article introduces the fractal theory briefly and gives detailed theoretical derivation on fractal dimension D. It has...

In response to global climate change, according to the policy attributes of carbon taxes and carbon trading, the paper designs two emission reduction scenarios, single carbon tax and the joint use of carbon tax and carbon trading, and builds the computable general equilibrium (CGE) model to simulate...

With the development of information technology, large scale intelligent information system has been widely used in the field of electric power enterprise management. This paper combines data quality characteristics and the significant problems that power system faces with, Constructing the index system...

A multi-Agent scheduling management system of distributed structure is proposed and an adaptive schedul-ing model which is aimed at the optimal economic benefits is established to explore more efficient methods for the scheduling problem of energy storage system. In a case that a model containing six...

One 600MW unit in a power plant in Guangdong Province was taken as the study subject to contrastively analyze four different smoke temperature lifting schemes through thermodynamic calculation. The result indi-cate the non-feasibility of the feed water bypass scheme and the economizer exit water bypass...

In the manuscript, the forming limit for cross-section distortion is defined according to the employing area and aviation standard. First, the definition and determination method of forming limits is proposed. And then, the effects of process parameters on forming limit are investigated based the 3D...

Recently, environmental issues are continuing to exert pressure on an already stretched world energy infra-structure. Significant progress has been made in the development of renewable energy technologies such as so-lar cells, fuel cells and biofuels. However, these energy sources have been marginalized...

This paper according to real grid power maintenance needs put forward a kind of live working robot, live working robot is developed for distribution live line work of a safe and reliable live working equipment. The live working robot vehicle control system, software and hardware realization of the motion...

At the present, the problem of energy crisis plaguing various countries in the entire world. China is also facing the huge challenges between energy supply and demand serious imbalances. The energy saving problem has become a hot social issues, which has received widespread attention. The key of building...

For manufacturing enterprises, holding a certain amount of inventory is necessary, excess inventory is not only useless but also occupied capital, therefore, inventory control is a good way to optimize the inventory struc-ture as well as to improve the utilization of the funds manufacturing enterprise....
