Montmorillonite, iron oxide and the composite, were synthesized and characterized. The behavior and kinetics of arsenic sorption on the three kinds of adsorbent were investigated under neutral conditions. The results indicated that the sorption capacities of iron oxide are higher than those of montmorillonite and composite. The kinetic data of arsenic adsorption can be well described by Lagergren-second-order...
Land Surface Temperature (LST) is a major concern in the earth science. Accurately retrieving LST from passive microwave data will promote work in many other research fields. In this paper, a simple linear relationship is developed to relate the microwave surface emissivities at vertical and horizontal polarizations for the channels of Advanced Microwave Scanning Radiometer-Earth Observing System...
This paper makes an attempt to address the scaling problem of Leaf Area Index (LAI) and to analyze the propagation of scaling effect of LAI. On the basis of the Taylor series expansion and following the general scaling procedure, it is demonstrated that the magnitude of the scaling effect is the product of the degree of the non-linearity of the retrieval model and the spatial heterogeneity of input...
This article used statistical data of recent two years. Under the condition that RMB satisfies Markov property, we used Markov chain to compute the frequency matrix and transition probability matrix and moreover, we predicted the future trend of exchange rate. We also simulated the original data using AR model, and added residual factor that is from analysis of Markov Chain. Finally, we got a model...
Conditional random fields (CRFs) model is the valid probabilistic model to segment and label sequence data. Comparing with other statistical models, such as HMM, MEHMM, CRFs process the data sequence in terms of the context of data. Chunk analysis is a shallow parsing method to simplify natural language processing. And entity relation extraction is used in establishing relationship between entities...
