In this paper, we propose a new traffic flow model, aiming to provide a possible explanation and meanwhile a useful simulation tool for the multi-fractal network traffic. It is shown that the Hurst exponent for the mainline traffic flow will appear crossover phenomena, if it consists of several self similar components with different Hurst exponents. Therefore, crossover phenomena are pervasive in...
The normal-inverse model arises as a normal variance-mean mixture with an inverse Gaussian mixing model. The resulting model, it is very complicated to obtain the influence measures based on the tradition method. In the present paper, several diagnostic measures for outlier data mining are obtained based on the conditional expectation of the complete-data log-likelihood function based on the EM algorithm...
With the development and application of modern science and technology, many new technical measurement methods have been put forward successively which are of high resolution and high collection rate about microseismic monitoring. We urgently need an effective detection method of abnormal data (mine earthquake) to collect lots of data to make real-time detection. In the past, we usually depend on experienced...
Regression-class is defined as a subset of the data set that is subject to a regression mode. Mining regression-class in heterogeneous data sets is attracting much attention in a variety of disciplines. Traditional data sets can't reflect prior information of data. In this paper, we consider ??fuzzy point data sets??, which is defined by giving a fuzzy membership to the data in exact data sets, for...
By using the quarterly data of 1996-2005 in China, this paper evaluates the usefulness of a monetary policy rule designed for developed economies. Drawing on our econometric analysis, we argue that the model comes closer to the data of China ,it is an ideal framework for chinese monetary policy analysis. The paper also suggests to make modifications of the typical policy rule to explain Chinese economy...
This paper proposes a 3d model data hiding scheme on a new local coordinate system, which is obtained by a vertex and its neighbors of the model. Embedding primitives are first transformed into local orthogonal coordinate systems and then to local coordinate spherical systems, messages are embedded by modifying the vertexpsilas longitude and latitude of the local spherical coordinate system. There...
Geospatial computing today is highly manual requiring large amounts of human capital. The systems used for processing were designed for stand-alone environments, are inappropriate for modern distributed, heterogeneous network environments as Internet due to their closed architecture, and their lack of interoperability, reusability, and flexibility. The need of an intelligent architecture that can...
