The B to C E-commerce Enterprise (B2CEE) has produced extensive and profound influence on the economic structure. To study the structural factors of stock price of B2CEE which will influence the market pricing of them, we have introduced fractal method and made an empirical analysis on the typical case of listed B2CEE. Furthermore, to reveal the true value of B2CEE, it must separate the trend factor...
A Minkowski fractal shape patch antenna covering terrestrial wireless services is presented for multiple-input-multiple-output implementation. The proposed structure is minimized upto two iteration operated at 10GHz. The end to end separation between the two antennas is 4.9mm The existence of surface waves is reduced using two inverted T and slot structure respectively, which is etched in between...
Fractal image compression is an image compression technique which is based on local similarity of image structure. Fractal image compression provides good quality of reconstructed image and high compression ratio with extra feature of fast decompression. Fractal image compression suffers from time consumption in encoding phase. This paper presents a method to reduce the complexity in coding time....
Heart rate variability (HRV) decrease has been described in patients with obstructive sleep apnea syndrome (OSAS). Nevertheless, time and frequency domain methods commonly used for HRV analysis are considered not completely reliable in case of respiratory and arrhythmic disorders. On the contrary, the nonlinear approach may supply powerful and promising tools to give a better insight of the autonomic...
This paper proves the China stock market to be a chaotic system and establishes a nonlinear dynamical model for it based on the study on the nonlinear dynamical properties of Shanghai stock composite index sequence by using chaos and fractal theory. The phase space of the stock sequence is reconstructed and the correlation dimension is analyzed, which indicate that the dynamical system has finite...
The landscape spatial pattern with large scale has been the research focus of the landscape ecology recently, but few researches pay attention to that how to choose a perspective to study the characteristics of the landscape pattern of the Qinghai-Tibet Plateau for its unique topography and the alpine ecosystem. This paper takes the 2010 Western Mapping Data as the main data source and uses GIS as...
In this paper, the multifractal degrees in a collection of Chinese market and industry indices are evaluated. Via the multifractal detrended fluctuation analysis (MF-DFA), the result shows that all the indices have the multifractal features, but their multifractal spectrums differ from each other. The average fractal dimension is also calculated and applied to measure the market risk. According to...
The paper deals with using so called singularity exponent in a classifier that is based on ordered distances of patterns to a given (classified) pattern. The approximation of probability distribution mapping function of the distribution of points from the viewpoint of distances from a given point in a form of a suitable power (exponent) of a distance is presented together with a way how to state it...
Illustrated with Qiantang estuary , Hangzhou Bay, the relationship between structure of coastal geomorphology and dissipation of tidal energy were analyzed and the landscape ecological mechanism of watershed flood was studied based on the theory of the landscape ecology and quantitative assessment method of landscape characteristic index. By Correlation analysis and multiple linear regression analysis...
This paper studies the correlation between the urban morphology and urban comprehensive strength. We select 31 cities with a population over one million in 1990 as our samples. Specifically, we introduce a powerful new clustering methodology, affinity propagation clustering, published in “science” in 2007, to cluster urban shape indicators. Then, using principal component analysis, we evaluate the...
In this paper, we use Multifractal Detrended Cross-Correlation Analysis(MF-DXA) method to investigate the cross-correlation of Chinese stocks, which expected to be correlated. The mentioned data are high frequency data recorded every 15s during 2009. We analyze the Shanghai Composite Index (SHCI) and the Shenzhen Component Index (SZCI), get the cross-correlation exponent 0.60. We determine generalized...
Middle and small size fault structure is the key geological factor affecting the safety production of DongPang mine field. Finding out development character of middle and small fault structure in DongPang mine field is to provide the geological premise for mining design of coal mine and working face layout. Based on the analysis of real data, 20 factors affecting the development of middle and small...
In each surgical operation, monitoring the depth of anesthesia is vital for anesthesiologists to control this depth during the surgery. Several methods have been suggested to determine quantitative indices for depth of anesthesia but most of these methods suffer from high sensitivity of their indices during the surgery. In this paper, to make the index more robust, a beneficial Electroencephalogram...
In the decade,the use of agent-based simulations of market has been acceptance by more and more social scientists. This paper presents the construction of the artificial stock market that the artificial intelligent algorithms take on the role of trades. They make predictions about the future, and buy and sell stock as indicated by their expectations of future risk and return. Prices are set endogenously...
Among the plethora of indices that can describe the fractal-like behaviour of heart rate variability (HRV), the fractal dimension (FD) and the power-law exponent (β) have gained wide acceptance. Since HRV is generally modelled with fractional Brownian motion (fBm), the linear scaling relationship between β and FD, valid for fBm, is often applied to HRV series to derive one index from the other. In...
We investigate the multifractal character of the realized range-based volatility (RRV) in Shanghai Stock Exchange Composite Index. Through the partition function approach, we estimate the Renyi exponent and the singular spectrum, it has been found that the RRV series have significant multifractal properities. By introducing the shuffled and the surrogate series, we find that the long range temporal...
This paper investigates the fractal characters of Baltic Dirty Tanker Index weekly return time series. BDS test and Rescaled Range Analysis are applied for studying non-linear dependence and random of the time series. The Hurst index and acyclic periodic is gained by R/S analysis. Conclusions show that there is non-linear dependence and non-random, also the series show inverse persistence.
In this paper, the Hang Seng Index data for the 22-year period, from December 31, 1986, to June 6, 2008 in the Hongkong stock market, are analyzed. Using rescaled range method, the Hurst exponent is estimated for financial time series and empirical evidence suggests that such market possess strong long-range dependence for both conditional time series and volatility. In order to get more information...
A short review of an algorithm, called Detrending Moving Average, to estimate the Hurst exponent H of fractals with arbitrary dimension is presented. Therefore, it has the ability to quantify temporal and spatial long-range dependence of fractal sets. Moreover, the method, in addition to accomplish accurate and fast estimates of H, can provide interesting clues between fractal properties, self-organized...
The Nanga Parbat Haramosh Massif (NPHM) is an active tectonic feature of the north-western Himalayas. The recent seismic activity lies on an active seismic zone between Sassi and Raikot, from north to south, and is called Raikot-Sassi fault zone. The drainage pattern of NPHM is disconnected at different location especially along the active Raikot-Sassi fault zone. The stream profile analysis of Indus...
