In modern agriculture, the interplay between complex physical, agricultural, and socioeconomic water use drivers must be fully understood to successfully manage water supplies on extended timescales. This is particularly evident across large portions of the High Plains Aquifer where groundwater levels have declined at unsustainable rates despite improvements in both the efficiency of water use and...
Social influence has been a widely accepted phenomenon in social networks for decades. In this paper, we study influence from the perspective of structure, and focus on the simplest group structure — triad. We analyze two different genres of behavior: Retweeting on Weibo1 and Paying on CrossFire2. We have several intriguing observations from these two networks. First, different internal structures...
This paper, taking Beijing, Tianjin, Shanghai of China for example, discussed the method of urban carbon emissions prediction. Using Yongbin Zhu and Zheng Wang's optimal growth model to study the energy carbon emissions of cities under steady economic growth, and getting forest carbon sinks of cities with CO2FIX model, then we could result in net carbon emissions of cities. The results showed that...
This paper employed the carbon dynamic model and IPCC cement model to estimate the amount of carbon emitted by energy and cement, and used CO2FIX model to predict the forest carbon sinks in Beijing, Tianjin and Hebei Province from 2009 to 2050, then, this paper analyzed the influential factors and the contribution of forest carbon sinks to carbon emissions reduction. The main conclusions are as follows:...
This paper discusses how to manage the low-voltage line loss which is used by the visualization, thereby assists power enterprises in reducing the low-voltage line loss. According to the characteristic of the low-voltage grid, change the managed object to the customers and transformers district, time to the daily data. And discusses how to calculate and analyze the line loss. About visualization,...
The Original TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) Method is a ranking method based on the principle that the chosen alternative should be as close to the ideal solution, rather than the negative-ideal solution, as possible. However, currently utilizing in establishing the evaluation system of indicator-based model, the Original TOPSIS Method is failed to take...
As rapid development of economy and people's gradually great attention to energy environmental problems, more and more researchers have started researching the relationship between economy, energy and environment, we urgently need methods and models to solve the disagreement between them, and so 3E-based forecast and early-warning models began to emerge, and develop towards high-precision and comprehensive...
