This paper studies the Shanghai Stock Exchange (SSE) Composite Index, sample period of which spreads from December 16th 1996 to December 31st 2009. The index close prices, its logarithm, its logarithmic first differences, and its log linear detrended series are used. To judge the existence of chaotic dynamical features in time series, the technique of phase space reconstruction is applied. The C-C...
Factor analysis and structural equation model are used to construct the model of flexible collaboration on engineering machinery, and it gets the following innovation conclusions firstly- the main factors of flexible collaboration on engineering machinery is descending as strategic synergy, cultural synergy, strain flexible, cooperative effects; And not only the relation of these main factors is relevant...
Quality of service is the core of service industry development, and is the most focused issues in service marketing research. Through reviewing the literature of service quality, this research studies the relationship of service quality, customer satisfaction and behavior intention. In this study, the railway passenger services as the empirical study object, the results show that rail passenger service...
This paper proposes a logistics alliance model of cooperative mechanism integrated by formation, implementation and constraint mechanisms by focusing on the study of "leader-member" logistics alliance. The empirical analysis demonstrates that this model reflects the general law of logistics alliance synergy.
Regional Logistics and regional economy have a significant correlation. From the perspective of the logistics industry agglomeration, using the logistics industry data of 31 provinces in China, selecting three main indicators impact on the regional logistics industry based on previous research, entropy method and cluster analysis, combining to have a empirical study on overall development and characteristics...
In this paper, we present a novel method for inductance extraction and modeling for interconnects considering process variations. The new method is based on the spectral stochastic method where orthogonal polynomials are used to represent the statistical processes in a deterministic way. Coefficients of the orthogonal polynomials are computed for the inductances. Statistical inductance values are...
An approach based on chaos theory and fuzzy neural network (FNN) is proposed for chaotic time series prediction. Firstly, C-C algorithm is applied to estimate the delay time of chaotic signal. Grassberger-Procaccia (G-P) algorithm and least squares regression are employed to calculate the correlation dimension of chaotic signal simultaneously. Considering the difficulty in determining the number of...
With the economic development, the logistics industry has been considered as one of the important of industries. Based on extension of input-output table in Zhejiang Province, using association analysis of the logistics industry, the development of logistics industry in Zhejiang conducted an empirical study, identified the position of the logistics industry in Zhejiang Province of national economic...
We consider the problem of randomly rounding a fractional solution x in an integer polytope P ⊆ [0,1]n to a vertex X of P, so that E[X] = x. Our goal is to achieve concentration properties for linear and submodular functions of the rounded solution. Such dependent rounding techniques, with concentration bounds for linear functions, have been developed in the past for two poly topes: the assignment...
With the large scale application of integrated circuit in the chaotic encryption, the design of cryptogram program based on the chaotic system becomes a new trend of cryptography. The digital degradation after the chaotic digitization is a key issue to be resolved, while current study pays more attention to digital chaotic period behavior, but the other characteristics of digital chaotic also plays...
A novel permutation-substitution scheme, which is based on chaotic standard map, for the image encryption is proposed. It is loss-less symmetric block cipher and specifically designed for the colour images. The initial condition & system parameter of the chaotic standard map, number of iterations and number of rounds constitute the secret key of the algorithm. Firstly we mix all three colour layers...
In this paper we introduce an ant-based algorithm on continuous domains used to create procedural animations. We focus our approach on finding movement sequences that satisfy both the physical constraints as well as animator requirements. The proposed method is very flexible and can be easily adapted to different situations and characters' morphologies. Our simulations show that the proposed technique...
This work is a new proposal of neural synchronization, which is a communication of two Tree Parity Machines (TPMs) for agreement on a common secret key over a public channel. This can be achieved by two TPMs, which are trained on their mutual output, which can synchronize to a time dependent state of identical synaptic weight vectors. In the proposed TPMs random inputs are replaced with queries, which...
Similarity between two sentences can be determined by either comparing their commonalities or their differences. Commonalities, which reflect similarity judgment, connect the two sentences while differences, which reflect dissimilarity judgment, represent the unique way of self-identification. Although both of them are essential in determining sentence similarity, however, the existing methods only...
The research on relationships among terrain, climate and vegetation is a main topic of ecological geography. Taking the moderate resolution imaging spectroradiometer based enhanced vegetation index (MODIS-EVI) and Parameter elevation Regressions on Independent Slopes Model (PRISM) data as the indices, we analyzed the spatial heterogeneity of vegetation in southern Yunnan province of China and its...
Coverage analysis defines the tracing of a program by test cases. It also helps in the testing process by finding the areas of a program not exercised by a set of test cases. Introducing new test cases to increase coverage, and determine the quantitative measure of the code, which is an indirect measure of quality. Coverage analysis provides more benefit when applied to an application that makes a...
Student users' acceptance is crucial to the success of open resources for university education. Drawing on the theory of reasoned behavior, technology acceptance model and flow theory, this research examines the factors affecting university students' acceptance of open resources for university education. We have collected 200 valid questionnaires and conducted data analysis with structural equation...
The inter-language studies on the textual semantic accessibility scale (SAS) are a new branch of the computational linguistics and the present paper tries to statistically probe into the SASes in English, French and Japanese literature works sampled from the corresponding corpora. Firstly, six control groups are formed by the equidistant texts extracted every 10 pages, 5 pages, 4 pages, 3 pages, 2...
Abstract-We consider the problem of testing if a given function f:F2n → F2 is close to any degree d polynomial in n variables, also known as the Reed-Muller testing problem. Alon et al. [1] proposed and analyzed a natural 2d+1-query test for this problem. This test turned out to be intimately related to the Gowers norm. Alon et. al. showed that this test accepts every degree d polynomial with probability...
In connection with the nonlinear dynamic characteristics shown from the performance of fault rotating mechanical system, based on the research and analysis, correlation dimension and complexity can be used to characterize the system state of motion.
