Frames play an important role in wavelet analysis. G-fra mes are generalized frames which include ordinary frames, a nd many other recent generalization of frames. In this paper, we give several theorems to construct a large number of new G-frames from existing G-frames.
The ecological footprint of Pinggu District in 2001 and 2005 was calculated and comprehensively analyzed. Results showed that the ecological footprint, ecological carrying capacity and ecological deficit in 2001 were 2.1464 hm2/cap, 0.3344 hm2/cap & 1.81204 hm2/cap respectively, and then 3.6172 hm2/cap, 1.8794 hm2/cap & 1.7378 hm2/cap in 2005. By contrast the results of 2001 with 2005's, it...
Express transportation is a major direction for railway freight transport, and railway freight transport centralization is the main basis for express transportation. With studies on the operation mode of railway freight transport centralization based on express transportation, the article believes that it is necessary for freight transport centralization to take information technologies as the major...
Characteristics of land use/cover change (LUCC), ecosystem service values change and their spatial heterogeneity of three-belt of mountain-oasis-desert in the northern slope of Tianshan Mountains, were analyzed, based on GIS and data of remote sensing and LUCC in 1989 and 2000. And related sustainable development countermeasure was put forward referring to rules of ecosystem services functions change...
In this paper, the performance of safety management in building construction in China is summarily analyzed. Considered the factors of the underlying causes of the construction safety accidents including staff, equipment, material, technique and circumstance, and combined with the latest study achievement of construction safety management at home and abroad, the underlying causes of poor safety management...
In view of the shortage of building safety data and the difficulty to collect them, we propose a new forecasting method based on support vector machine in this paper. We analyze some casualty data and construct a forecasting model with the method of support vector machine. The experiments prove that the method has advantages of lower error in simulation and higher precision in forecasting comparing...
