Texture feature is a measure method about relationship among the pixels in local area, reflecting the changes of image space gray levels. This paper presents a texture feature extraction method based on regional average binary gray level difference co-occurrence matrix, which combined the texture structural analysis method with statistical method. Firstly, we calculate the average binary gray level...
Transmission of videos in error prone environments such as mobile communications, may lead to video corruption or loss so that received visual quality is degraded. Therefore, it is essential to implement efficient and low complexity error concealment methods which allow visually reducing the degradation caused by the missing information. The contribution of this work is to report the results of a...
Unknown word recognition is a key issue in Chinese information processing. The traditional algorithms of unknown word recognition can be broadly classified into two types: the rule-based methods and the statistical methods. However, these algorithms have some limitations in identifying the unknown words which are created on Internet. The unknown words of Internet have no obvious rules and are composed...
The results of the analysis of the year-long (2007) monitoring of the night time data of the VLF signal amplitude from the Indian Navy station VTX at 18.2kHz, received at the Indian Centre for Space Physics, Kolkata, are presented. We analyzed this data to find out the correlation, if any, between the night time fluctuation and the seismic events. We found, using individual cases (with magnitudes...
Firstly, the article defined the concept of internet mouth in different research fields; on the base of realistic condition of Chinese electron commerce, the influencing factor model of internet mouth of dissemination credibility was built. In the analysis validated, website credit, information frame, the character of information disseminator, the specialty of information embracer, the connection...
Through empirical study, this paper tests the effect of member age of the board of directors and independent characteristics on corporate performance from 863 listed companies of Japan, and the result shows that average member age of the board of directors and corporate performance are significantly positively correlated, independent director system is advantageous in improving corporate performance,...
We define and compare statistical characteristics of estimate of mean power of signals reflected from meteorological formations (MF). Their dependences on training sample size, power of MF, type and level of interperiod correlation of reflections from MF are analyzed. Rational ways of practical implementation of MF mean power estimate are demonstrated.
We define and compare the statistical characteristics of the estimates of Doppler velocity spectrum (DVS) width of meteorological formations (MF) based on the various modifications of “pulse pair” method. For the conditions, when the form of unimodal DVS differs from the Gaussian one, the errors of proposed modification of “pulse pair” method are evaluated, and possible ways to reduce them are proposed...
By using traditional statistic quantile method, Geography Information system (GIS) analysis and spatial autocorrelation statistical techniques, this paper calculated the grid population density, detected the trend of population distribution, studied the spatial relationship and characteristics between prefectures through spatial autocorrelation statistical techniques. The conclusions are got from...
Spatial autocorrelation is an important spatial statistical method in Geographic Information Systems, which can reveal spatial structures and patterns of regional variables. With this method, this article calculates the population density's spatial correlation model for county-level units in Jiangsu province of China in 2001, 2002, 2003 and 2004, explores and demonstrates every county-level's global...
As student satisfaction surveys are a primary method of evaluating university faculty teaching performance, it is essential to develop an understanding of the factors driving course evaluation. Here we discuss experiments conducted to investigate the value of various service actions in the classroom environment. In particular, we focus on the offering of excitement needs such as giving candy, humor,...
In order to examine whether there is profit characteristic in Chinese low-profits companies. This paper conducted a survey on the related listed companies in Chinese A-share market. We extract a number of profit targets based on the financial statement, and analyses the financial data of listed companies in 2007–2009. The results show some characteristics of these companies. Finally, the paper makes...
The ratio of NPLs (non-performance loan) is one of the important indexes of assessing the security of credit assets, as well as it is an essential financial indicator to overall strength in commercial banks. In this paper we establish a time series model for the ratio of NPLs of Chinese state-owned commercial banks, taking the statistical data of the NPLs from 2002 to 2010 as an example, basing on...
With the popularity of Internet Consumption, students who are high-connected with internet turn into the main source of consumption online, so they have already become an important part of segment market that cannot be overlooked, coming along the online sales activities. For this reason, getting a better understanding of the characteristics of college students' online shopping behaviors, as well...
The influence of regional culture and values on the Chinese human resource market has been steadily increasing, but unconsciously. In recent years scholars have studied a variety of phenomena that imply a shift-away from classical explanations of talent flow and human resource patterns. This has led to the coining of some new terms and concepts, such as "Ant Tribe". This tendency towards...
Through empirical study, this paper tests the effect of board size and two-level state toward s corporate performance from over 800 manufacturing listed companies of Japan, and concludes that board size and corporate performance a re significantly positively correlated, one of two staff, board chairman and general manager, in high-growth enterprises is significantly positively correlated with corporate...
This paper is based on data analysis and literatures, land use system, demographic factors, and economic development situation, fiscal and financial policies which have influence on the price of the house are studied. In order to discuss housing price purely on the basis of statistical data, the main factors and their weights are calculated based on the survey of house price and usage of grey theory...
Although the amount of spring rain is only 10% of total rainfall in Taiwan, it plays an important role of water resource allocation during drought periods. Therefore, increase the rainfall forecast ability will help the combination of surface water and groundwater usage during drought period, it will also help early warning and policy decision. This study focused on local rainfall characteristic and...
In order to study the spectral density properties of 900MHz radio signal, the time series theory is introduced into statistical analysis. By means of the statistical data from signal acquisition system, the spectral density analysis principle is introduced. Moreover, both the autoregressive (AR) spectral estimation and autoregressive moving average (ARMA) spectral estimation are taken into spectral...
For 45 nm and beyond, direct polished porous type ultra low-K film (ULK) is integrated in Cu interconnects. Post-cleaning of Cu CMP effect on Time dependent dielectric breakdown (TDDB) was investigated. Cu ions remaining on dielectrics and Cu roughness are found as two dominate factors at different clean time region. High Cu roughness induced capping layer seam results in the degradation of TDDB....
