We discuss the Optical Image Matching Technique, which cloud obtains the horizontal ground deformation by using the frequency domain phase correlation technique and Fourier migration theory. Then, we retrieved the fault rupture of the 2014 Mw6.9 Yutian earthquake from GF-1 and ZY-3 images, both of which are Chinese optical satellites. The experiment indicates the ability that Chinese optical satellites...
Satellite data transmission scheduling is assigning limited ground resources for satellite data requests reasonably in the condition of many satellites and ground stations with considering many constraints. Its purpose is improving the efficient usage of ground resources. In this paper, we focus on the building of satellite data transmission scheduling and algorithm. We describe the constraints of...
For QPSO (Quantum-behaved Particle Swarm Optimization) algorithm's disadvantages of premature convergence and easily getting into local extremum, an improved QPSO algorithm called co-evolutionary QPSO algorithm with two populations is presented in this paper. Particles are updated by adopting QPSO algorithm inside populations and by using annexing or cooperation operator between populations. The annexing...
Earth observation satellite mission planning is the core issue of multisatellite and multitask to coordinate control and scheduling problem. In this paper, the 0–1 integer programming model for satellite mission planning problem was constructed. We discussed the discrete particle swarm optimization (DPSO), designed decimal encoding operator of DPSO and decoding method based on the utilization of satellite...
Present a method for computing the embedded depth in rock of the laterally loaded rock-socketed piles. The method, based on the Hoek-Brown failure criterion, takes into account the mobilized lateral shear resistance along the bond of perimeter of the pile in rock. The proposed method is verified to be more reasonable by comparing its result with that of other existing methods.
In this paper, we present a review of the deregulation of energy prices in China between 1981 and 2007, and assess the impacts of changes in energy prices on aggregate energy intensity. We concluded that raising energy prices is an effective policy tool for decreasing energy intensity by increasing efficiency of energy use. According to research, the author suggests that, to save more energy, in addition...
Decomposition analysis has been popular in the study on influencing factors of CO2 emissions. This paper analyzes the change of CO2 emission intensity in China over the period 1980-2007 based on a complete decomposition approach-the logarithmic mean divisia index (LMDI) method, and examines the factors driving the changes of CO2 emissions intensity. The research shows that energy intensity is the...
Decomposition analysis has been popular in the study on influencing factors of CO2 emissions. This paper analyzes the change of sectoral CO2 emissions from the three main industries in China over the period 1980-2007 based on a complete decomposition approach-the logarithmic mean divisia index (LMDI) method, and examines the factors driving the changes of CO2 emissions. The research shows that economic...
Energy intensity is crucial to the development of a society. China experienced a dramatic decline in energy intensity from the onset of economic reform in the late 1970s. Decomposition methodology is a useful analytical tool in energy consumption and energy intensity analysis, to the best of our knowledge, no decomposition study has taken into account the price index. In this paper, we use the decomposition...
Decomposition analysis has been popular in the study on influencing factors of energy consumption. This paper takes a quantitative analysis on factors which affect energy consumption in China during 1980-2006 based on logarithmic mean Divisia index (LMDI), and examines the factors driving the changes in energy consumption. The research shows the improvement of energy efficiency decreased energy consumption,...
Decision-making information often has uncertainty because of inaccurate estimate and survey error. This causes the quantification of information to appear in the form of intervals. To solve the multiple attribute decision-making issues of interval number, a new method based on fuzzy theory is put forward. On the basis of this method, different schemes of the water resources allocation in a certain...
The first hypothesis proves that there is a correlation between intellectual capital and market value in Chinese capital market. The correlation is significant over the entire examined period. What this strong correlation further implies is that Chinese listed companypsilas perceived value, to a certain extent, in today knowledge economy, is related to the companypsilas intellectual capital. The second...
Semantic pattern is kind of template with semantic information, and it can be used to structurized a sentence. In this paper, semantic pattern based question and its corresponding answers are used as the data resource of knowledge base. The exact answer is extracted from plain text answer by matching of question and answer. Two kinds of matching methods and the experiment results are simple presented...
