Wavelet analysis has been a widely applied one method for analyzing signal. In this work, the notion of vector-valued wavelet packets for space L2(Rn)s is proposed, which are generalizations of univariate wavelet packets. A constructive method for a class of biorthogonal vector-valued multivariate wavelet packets is formulated and their biorthogonality properties are discussed by virtue of matrix...
Relative carrying capacity of resources is a method for measuring sustainable development through carrying capacity. Case studies of eleven cities in Zhejiang (Hangzhou, Ningbo, Wenzhou, Jiaxing, Huzhou, Shaoxing, Jinhua, Quzhou, Zhoushan, Taizhou and Lishui) illustrated regional sustainable development approach. In this study, in order to provide insight into spatial analysis of region sustainable...
In the past, we evaluated damage effectiveness of shrapnel pill ignoring dispersing blind area. Researches and experiments show that dispersing dead area of shrapnel pill is in existence. The math model of stochastic producing method of bullet falling point when taking into account dispersing dead area is set up, damage effectiveness when considering dispersing blind area based on two representative...
Responses of hydrologic process to human induced land use changes, which have affected a wide portion of China since last century, were evaluated with a coupled land surface-hydrology model. The main land use changes were assessed by the International Satellite Land Surface Climatology Project (ISLSCP) historic (1970) and potential land use types in the Huaihe River basin. The variations of flood...
Information on genetic diversity and differentiation is essential for conservation and stock improvement programs. AFLP technique was applied to analyze the genetic diversity and differentiation of one wild and three hatchery Haliotis diversicolor supertexta populations. In general, our results showed a reduced genetic diversity in the three hatchery populations when compared with the one wild population...
Al-pillared montmorillonites (Al-MMT) were synthesized from natural occurring sodium montmorillonite through the exchange of inter-lamellar ions with hydroxyalumina polycations. Furthermore, the morphology, composite structure and pore properties of such composite materials were investigated by Powder X-ray Diffraction (XRD), Fourier Transformation Infra-red Spectra (FTIR) and Nitrogen Adsorption-Desorption...
A study was initiated in a small semi-arid catchment with reforestation history to elucidate the soil change. Results showed that land use pattern was closely related with terrain conditions and human disturbance levels. Soil properties under four typical human-disturbed land use types (orchard, shrub, cropland and reforested land) were compared. Significant differences were found for total nitrogen...
According to hydrologic similarity, that means the grids of the same topographic index were classified into the same runoff unit, TOPMODEL calculates runoff yield. However, spatial heterogeneity of basin terrain and geomorphology information such as rainfall and topographic index statistics distributed curve etc. is not considered. This paper, trough treating basin DEM, obtains sub-basins based on...
The specific studies are carried out according to the problem of the high concentration of fluorine in Yangshapao Lake, which is a most important multi-purpose reservoir of Diversion Project from Nenjiang River to Baicheng City in Western Jilin Province. After the diversion is actualized, the release of fluorine from the sediment may influence the water quality in the reservoir. Based on the problem...
In view of the defect of traditional water quality evaluation model, a probabilistic neural network (PNN) is developed to evaluate surface water quality in Jining. Probabilistic neural network is a new type neural network consisting Radical Basis network and compete neural network, which is simple in structure, easy for training and wide used. PNN model is applied to evaluate water quality at representative...
Industrial wasteland tourism has rapidly developed in China. In this review, we discussed the progress in tourism resources and tourism planning, including value evaluation of tourism resources, resources and products development, development orientation of tourism, tourism landscape planning method and technology, and the international successful cases. The results show that in contrast to other...
This paper discusses the unique climatic resource in the Xiangxi river valley. The features of the climatic resource in the area can be concluded as follows: 1. It is very warm in winter and frost period is short. 2. According to the sea level elevation, the mountains can be divided into several climatic zones. 3. Precipitation is even around the whole year so that rainfall can be used effectively...
Amplified fragment length polymorphism technique has been applied to detect the genetic diversity and differentiation of three wild Haliotis ovina populations in Hainan province, China. High level of genetic diversity was detected among the populations. The mean effective number of alleles per locus was from 1.2027+0.3090 to 1.3530+0.3404, with an average of 1.2969+0.3338. The percentage of polymorphic...
Environmental pollution has been a serious threat to all people's living conditions, restricted the ability of continual economic development. How to control the pollution scientifically, efficiently and rapidly has been one of the important topics in the technology research around the world. So, the guiding principles, the organization and the responsibility of the design of environmental pollution...
Now more and more application demand to spatio-temporal database is proposed and the spatio-temporal data model is the fundamental basic to spatial-temporal database. But till today the study on spatio-temporal data model still more concerned with the theory research. The article proposes a new model-the change-of-feature based spatio-temporal object relational data model by researching and analyzing...
The genetic diversity and differentiation between wild and hatchery Haliotis asinina populations were tested by allozyme and AFLP techniques. The results from allozyme technique showed that there was a decline in mean number of alleles per locus, percentage of polymorphic loci and observed heterozygosity and a change in allele frequency in three loci, SDH-1, AAT-1 and EST-1. Allelic richness, percentage...
In order to investigate the retardation of water evaporation by single and mixed monolayers at air/water surface, surface pressure (pi)-time (t) isotherms, specific evaporation resistance (r)-temperature (T) curves had been used to describe the properties of monolayers made from single monolayers of 1-hexadecanol (C16OH) and mixed monolayers of C16OH and nonionic surfactants. The results showed that...
In this study, coking wastewater was treated using different coagulants to make it meet requirements of the secondary standard described in ldquoIntegrated wastewater discharge standardrdquo. Coagulation using PFS and PAC respectively was performed to study effect of coagulant dosage, and pH on removal ratios of colority, CODcr and turbidity. It is found that optimum dosage and pH are 50 mg/L and...
This paper presents a investigation of pollution originating from coal ash in Jingangshan thermal power station Jiangxi province China. About half of coal ash obtained by coal combustion in the power plant is mixed with ash-flushing water (most of the ash-flushing water from Ganjiang river) and transported to the ash field through the pipeline. In order to assess pollution caused by leaching of some...
Because of the defaults of long positioning time, weak positioning signal and low positioning accuracy based on the technology of GPS/GSM, a new position service based on the vector map was presented. The system can provides many services, including self-positioning, city guides, tourist guide and logistics system. Moreover, the basic principle of GFSOne was introduced. As an example to Xiangtan region,...
