So far there exists no general, common specification for multi-resolution modeling (MRM) to represent models consistent with each other. To address this problem, a new formalism, multi-resolution DEVS (MR-DEVS) is put forward. The definition of multi-resolution entity (MRE), which is the basic object MRM deals with and base for MR-DEVS, is given. Then, MR-DEVS, combining and extending multiple popular existing dynamic structure DEVS formalisms, is elaborated in detail. MR-DEVS is capable of capturing all key characteristics of MRM essentially, including adapting to resolutions changing automatically by reflection, describing consistency mappings and modeling causation by consistency mapping functions and modeling emergence by functions of coupling among sub-entities constituting the same MRE. Any other existing formalism can't do these all.

Object-oriented change detection is more practical than per-pixel change detection when we survey change information of land-use using remote sensing image. A kind of land-use change detection based on patch objects of remote sensing image is studied in this paper. The patch objects of image come from the polygons of historical vector land-use map. The method calculates the weighted correlation coefficient of each patch object in order to identify whether the patch object is changed. Two different time-series SPOT images in a suburb of Shanghai are used to verify the method. The result shows that the method can detect the changes effectively and raises automation level of land-use updating investigation.

We propose an approach to computing two-dimensional unstable and stable manifolds of three-dimensional vector fields. The main idea is to estimate normal direction on each point around the boundary of current loop of manifold and normalize the normal growth rate during a settled time step to counter the disequilibrium in different directions. In order to enhance the reliability of our approach, linear and nonlinear conditions are considered. It is necessary to state that the time step should be appropriately small to meet the adjacent intervals of points on the boundary of manifold. As example we compute the two-dimensional stable manifold of the origin in Lorenz system. Both successes and shortcomings of our method are presented.

A study of the adsorption kinetics of 1-octanethiol and 1,8-octanedithiol has been carried out on gold electrode by cyclic voltammetry with different concentrations. Analysis of the kinetic data show that the adsorption kinetics of 1-octanethiol and 1,8-octanedithiol can be satisfactorily described by Diffusion controlled Langmuir(DCL) model, irrespective of concentration. The rate constants of 1-octanethiol and 1,8-octanedithiol are almost invariable at different concertrations, however, the fluctuant range of 1,8-octanedithiol is larger than that of octanethiol. The rate constants of other alkanethiol(n=12,14,16,18) are measured and tunneling parameter (β) is determined from these data

A regional air-sea coupled climate model based on the regional climate model RegCM3 and the regional oceanic model POM (Princeton Ocean Model) is developed and a series of experiments are performed to verify the ability of the coupled model to simulate the summer precipitation over China from 1963 to 2002 in this study. The simulation results show that the regional air-sea coupled model RegCM3-POM has a better performance in simulating the mean summer (from June to August) precipitation over China, and the distribution of the rainband in the coupled model is more accurate than that in the uncoupled model RegCM3. The improvement of the rainfall simulation ability is remarkable over the Yangtze River Valley and in South China. Compared with the ECMWF ERA40 re-analyses, the convective precipitation simulation ability of RegCM3-POM has been improved. The space correlation coefficients between the results of RegCM3-POM and ERA40 data are above 0.6, and the coefficients between the results of RegCM3 and ERA40 data are about 0.4. The stratiform precipitation simulation ability of RegCM3-POM is also improved. However, both the two models overestimate the percentage of convective precipitation, and underestimate the percentage of stratiform precipitation. In order to improve the simulation ability of precipitation, the cloud precipitation schemes of the models may be modified.

In this paper, we address the problem of a unique equilibrium point and present global asymptotic stability for Hopfield neural networks with time-varying delays. By constructing a Lyapunov functional, a new stability criterion for the network is established in terms of differential inequality technique. Finally, an illustrative numerical example is included to show the effectiveness of proposed criterion.

Invariant image representation plays an important role in many pattern recognition applications, such as texture classification, face recognition and character recognition. In this paper, we evaluate some of the invariant orthogonal moments, including Zernike moment (ZM), pseudo-Zernike moment (PZM), and Polar Harmonic Transform (PHT), which are all computed in a circular domain. The performance of invariance and image representation ability are evaluated.

In addition, the software GEOMAGIC STUDIO was used to extract the tree measuring factors accurately. By comparison of the error analysis concerning scanning value and measuring value, the results have met the precision requirement of forest investigation factor, providing as the data support for certain area in measurement of 3D green biomass and its model establishment. It can also provide as guarantee for digitalization and informatization for forestry in the future.

In [1], the boundeness of one dimensional maximal operator of dyadic derivative is discussed. Unfortunately, the proof is uncorrect. In this paper, we consider the maximal operator of dyadic derivative on Vilenin group. With the help of counter-example we prove that the maximal operator is not bounded from the Hardy space Hq to the Hardy space Hq for 0 < q ≤ 1.
