An extension of local binary pattern, named Number Local binary pattern (NLBP), is presented for texture analysis. First, the method divides the patterns into uniform and non-uniform according to the uniform measure. Second, the non-uniform pattern is further divided into different groups based on the numbers of '1' bits and '0' bits. The experiment shows that NLBP achieves a good texture discrimination compared with the state of the art methods such as Uniform Local Binary Pattern (ULBP) and Extended Local Binary Pattern (ELBP). © 2011 IEEE.

Mining of association rules is an important research topic in web usage mining. The purpose of this paper is to research how to dig interesting association rules effectively from the Web logs after been preprocessed. Firstly, using the FP-growth algorithm for processing the web log records, obtaining a set of frequent access patterns, then using the combination of browse interestingness and site topology interestingness of association rules for web mining, discovering a new pattern to provide valuable data for the site construction. © 2010 IEEE.

The transformation on the demand for Food plays an important role in the adjustment about prices of agricultural products and agricultural structure. The study, by utilizing the extended linear expenditure system, analyses the food consumption structure of rural residents in the Ganzhou of Zhangye city, determines the basic food consumption demand, the marginal propensity of consumption, the income elasticities of demand, the own-price and cross-price elasticities of local rural residents, which illustrates the influencing factors about food consumption of rural residents and forecasts the food consumption structure. The results show that the rural residents' expenditure on household basic food consumption reaches about 7050.35 Yuan; the marginal propensities of consumption for fruit and vegetable are relatively high (respectively, 0.062 and 0.106), followed by meat (0.044); the demands for various food are increasing, as income increasing, the largest income elasticity of demand is corresponding to fruit (1.354), the lowest to cereal (0.310); the fruit and vegetables own the relatively high own-price elasticities (respectively -0.879 and -0.442), the cereal owns the lowest one (-0.184). The price increase of cereal will greatly affect demand for other products; the consumption for meat is decreasing whereas for cereal is increasing with the rising size of rural households; As the improvement of household education level, it will lead to increased consumption of fruits (E = 0.297); the amount of cereal expenditures is continually growing nevertheless the share is declining with the increase of household income in 2012-2020. Therefore, making sure the stability of cereal output the government should encourage the cultivation of Economic crops and guide the development of stockbreeding. In order to attain the balance between supply and demand, it is important to adjust rationally the prices of fruits and vegetables on the basis of the stable price with cereal. © Maxwell Scientific Organization, 2015.

Water resource is the basic and necessary input in the process of production and various consumption patterns of products and goods causes cause different impacts on the water resource using. It is very important to analysis and measures those different influences, which is especially good for the sustainability of water resource, construction of sustainable consumption pattern and the implementation of Integrated Water Resource Management. In this text, the virtual water consumption of Gansu in 1992-2005 is taken as a case study to analysis the relationship between the consumption pattern and virtual water. Then, three replaceable patterns presumed to examine and measure the change of virtual water. Based the results of this study, the per capita virtual water have decreased 43% and the total virtual water 40% in 2005 (relative to 1992). The quantity of food consumption decreases and the milk increases evidently. The key issue to decline the virtual water is the per capita virtual water consumption taken as the "quality" aspect of the virtual water and the more vegetable less meat can save virtual water 9% utmost. © Maxwell Scientific Organization, 2015.

The traditional agricultural economy dominated by the extensive economic growth mode and the impact of food crops production on agricultural ecological economic system cannot be ignored. In this study, the emergy analysis method was employed to describe the influence of food crops production and consumption on agricultural system and also some results and conclusions bring forth suggestion on food crop production in Zhangye city. © Maxwell Scientific Organization, 2015.
