Related literatures about ecological fragile is reviewed; the current status of ecological environment in the upper Min River basin is summarized. Equations for calculating the ecological footprint and ecological carrying capacity, as well as the standards of evaluating the status of ecological...

The influences of hydraulic retention time, temperature and free buffer on the performance of short-cut denitrifying microbial fuel cell were investigated after it was successfully started up using nitrite as the cathodic electron acceptor. The results revealed that a power density of...

Due to the excess consumption of natural resources and the severe deterioration of the environment, people are having a growing consciousness of environmental protection and more concerned of air pollution problems. However, the thermal power plant, as one of the main pollution sources, burns a...

A model-based dynamic multi-parameter method for peak power estimation is proposed for batteries and battery management systems (BMSs) used in hybrid electric vehicles (HEVs). The available power must be accurately calculated in order to not damage the battery by over charging or over...

After the discussions to exponential and power model [F. Dai, 2005], this paper points out there are three kinds of basic modes in the macroeconomic process, i.e., the exponential, power and logarithm mode, and discusses the logarithm model of Development Power (DP). By the analysis on logarithm...

This paper presents an experimental study of the alcohols–gasoline and gasoline–alcohols dual-fuel spark ignition (DFSI) combustion for knock suppression and higher engine efficiency using a gasoline engine with high compression ratio. Alcohols–gasoline DFSI is organized using a port fuel...

Accurate forecasting of wind speed and wind power is important for the safety of renewable energy utilization. Compared with physical methods, statistical methods are usually simpler and more suitable for small farms. Based on the methods of wavelet and classical time series analysis, a new...

Wind speed forecasting is one of the most important technologies to guarantee the wind energy integrated into the whole power system smoothly. In this paper a hybrid model named EMD–ANN for wind speed prediction is proposed based on the Empirical Mode Decomposition (EMD) and the Artificial...

This paper investigates generalized synchronization of three typical classes of complex dynamical networks: scale-free networks, small-world networks, and interpolating networks. The proposed synchronization strategy is to adjust adaptively a node’s coupling strength based on the node’s...
