The following topics are dealt with:compound fuel preparation; land use classification; electricity load forecasting; sandstone gas reservoir; underground gas storage facility;buried hill fractured reservoir; Sheshui River watershed; artificial cultivation; lake evolution; soil erosion; artificial rainfall experiment; multiscale bivariate wavelet packs; remote sensing image fusion; alteration information...
It is a good way to reduce and reuse the mined refuse using municipal solid waste(MSW), sewage sludge, pulverized coal and others to prepare compound fuel. A L16(45)orthogonal test design was used to study mechanical and combustion properties of the fuel, there were 16 treatments with 3 replicates. Applying the statistical soft system of SPSS13.0 for windows to analyze the influence of preparation...
High spectral resolution, high spatial resolution and high temporal resolution are the development trend of modern remote sensing technology. In the case of same image data, it is difficult to obtain high spatial resolution and hyperspectral remote sensing data information simultaneously. This weakness can be remedied, the quality of the image can be improved and the useful thematic information also...
Improving the accuracy of electricity load forecasting is benefit to the economic efficiency and social efficiency of electricity system. The rural electricity load forecasting is closely related to the agricultural industry. In the policy of advocating increasing farmers's incomes strongly, the accurate forecasting of rural electricity load is more important. The gray model is widely used and it...
Inventory verification is a process which tracks down inventory, storage capacity, working gas capacity, cushion gas and cushion gas loss in multi-cycle operation of underground gas storage facility (UGSF). This process is a key step to study the UGSF operation rule, analyze the gas loss, improve the operating efficiency and reduce the operating cost. Inventory verification model was successfully...
Rebuilding gas storage in Huabei carbonate and buried hill reservoir is very important to guarantee safe and balanced air feed to Jing, Jin and Ji regions, it has advantages of integrated structure, big scale closure and good flow condition of network of fracture. Though having developed deep research on rebuilding Ren-11 underground gas storage in Huabei massive and bottom water carbonate oil reservoir,...
A risk assessment for water shortage is constructed to analyze the carrying capacity of water resources in Sheshui River watershed, China. It is based on the information of present economic development. There are several serious environmental problems which might cripple the development potential in Sheshui River watershed. Risk assessment results are used to analyze the carrying capacity of water...
Nostoc flagelliforme, which grows in arid or semiarid steppes of the west and westnorthern parts of China, has a potential application in the ecological restoration of the damaged ecosystem in there. The reducing and slowly grown material is potentially the main limiting factor for the scale-up cultivation and application of it. In this paper, to prepare as many short vegetative filaments as possible...
This paper can be divided into four historical stages that discussing the impacts of human activities on lake evolution in the middle reaches of Yangtze River. Its natural environment has been influenced by human activities since the human beings moved into the lake area in the middle reach. But the impacts were limited till Yuanmo-Mingchu. After the Mid-Ming Dynasty, it entered into a large-scale...
This paper discusses a new non-linear tangent direction controlled subdivision scheme for curve interpolation. Given a sequence of points with their tangent directions, every adjacent pair of points and their tangent directions make a new point and its tangent direction, this operation generates a new sequence of points and their tangent directions, this is one step of subdivision. Repeat this process...
Most traditional mobile robots have always had problems when working in obstacle-dense environments and rough terrain. Inspired by the locomotion mode of locust, this paper presents the design of a novel jumping robot. Rationality of the design and the performance of the jumping mechanism have been verified by strength analysis and kinematic modeling.
This paper describes an illumination normalization technique which works at the pre-processing stage where the face image is first divided into equal sub-regions. Each sub-region is then processed separately for illumination normalization. Then the segments are joined back followed by further processing like noise removal and contrast enhancement. The proposed technique is tested on Yale dataset and...
Chemical conditioner provide new territory for studying China's agricultural practices, and for soil and water conservation. This study applied different consistencies of soil conditioner-polypropylene acid to China's Loess. This soil conditioner was elected macromolecule polymers of high water absorption strength in early water retention test. Through indoor soil sample's Scanning Electron Microscope...
The rise of frame theory in applied mathematics is due to the flexibility and redundancy of frames. In the work, the notion of bivariate affine pseudoframes is introduced and a class of a bivariate generalized multiresolution analysis (GMRA) is introduced. A new approach for constructing one GMRA of Paley-Wiener subspaces of L2 (R2) is provided. The sufficient condition for the existence of a sort...
Wavelet analysis is a popular subject in science research. In this work, the concept of biorthogonal two- direct- -ion finitely supported wavelet packs with four-scale is introduced. A new method for designing two-directional biorthogonal wavelet packs is developed and their properties is investi- -gated by means of time-frequency analysis method, matrix theory and operator theory. The decomposition...
Remote sensing change detection is a hot issue in recent years. However, most methods originate from statistical pattern recognition. Parameter resolution and time-consuming are main disadvantages of these methods. Hence, in this paper we propose a novel remote sensing change detection method which originates from neural network pattern recognition. The method is based on Growing Hierarchical Self...
The city environmental protection information system is a complex system, which integrates multi-system multi-technique and deals with larger quantities of environmental data. In the paper, introduce the system based on workflow, the system could deal environmental information automatically by using a lot of technologies such as workflow, web and multi-tier architecture, etc. the system could adjust...
