The residual life prediction of aero-engine is important for ensuring flight safety and reducing operating costs for airlines. Since there are varied performance parameters of aero-engine, it is difficult to use comprehensively these performance parameters to predict the residual life. This paper exploits Support Vector Regression Machine (SVR) in predicting the trend of varied performance parameters...
South-to-North Water Transfer Project is the strategic move to implement the water resource allocation of China. The east line of the project is carrying out which would bring with it a lot of water environmental and ecological problems because of the wide range, long time and complex environment problems facing as well as some uncertainty the environment and ecology themselves have. In this paper,...
Luoyang city is a region which is short of water resources in total amount. According to the amount of the available water resources, it can only maintain status quo. But it is estimated that it will lack water resources 2.43×108m3/a in the year 2010. For ensuring the speedy and sustainable development of economy in Luoyang City, the development and utilization of water resources have become one of...
The multiple quantum wells (MQWs) InGaAsSb/AlGaAsSb laser diodes (LDs) with an emission wavelength around 2.0μm were designed and fabricated by molecular beam epitaxy (MBE). The good performance of LD was achieved, with the low threshold current of 225 mA, and the slope efficiency of 0.23 W/A, respectively. The maximum outpower of 16 mW at 500 mA drive current was obtained at room temperature(RT).
In this paper, the necessity and possibility of the system-integration on flood-control decision-support system is demonstrated, and its ideology, rules and relevant key solutions is discussed. Based on the research for Biliuhe Reservoir, an integrated system for flood-control decision-support is designed under the environment of Browser/Server mode and network database. Under unified WebGIS platform,...
The spreading of faults and serious failures in many large-scale engineering systems is today one of the issues of the highest concern. This paper presents a novel method for modeling the fault propagation behaviors from the perspective of complex network theory. By focusing essentially on the topological structure properties of the underlying system network, several principles that are capable of...
