The paper concerns the measurement and forecasting of technological change, a topic relevant to many high-tech organizations and their customers. We revisit recent and classic data sets from technology forecasting data envelopment analysis (TFDEA) research and technometrics in light of a new visualization technique known as t-Distributed Stochastic Neighbor Embedding (t-SNE). The technique is a non-linear...
Due to process disturbances and some uncertainties, the process operating performance will deviate from the optimal operating point along with time, so it is very important to develop strategies for online operating performance assessment on optimality. However, a little work has been published in this research area to our knowledge. In this study, a new online operating optimality assessment method...
In this paper, five gold stocks in Chinese Shanghai and Shenzhen A-share and Comex gold futures are chosen to be the sample, for the purpose of analysing on the impact of the fluctuation of the international gold prices on the gold stocks in Chinese Shanghai and Shenzhen A-share. Using the methods of unit root test, Granger causality test, VAR model, impulse response function to comprehensively analyse...
This paper takes property price excluding core CPI as the indicator of the bubble degree in the empirical study of American, Japanese and Korean real estate market and come to the conclusion that real estate bubble is at least dependent on income and credit. Furthermore, bank-dominated financial system fuels the housing price in both bubble booms and bursts. Actually, the effect of real estate bubbles...
This paper uses the data of 16 China's listed commercial banks between 2007 and 2010 as the samples to go through the substantial evidence test of the relationship between commercial bank's earnings management and cash dividends policy, on the basis of using the abnormal loan loss provision measurement and avoiding surplus loss measurement to measure commercial banks' earnings management. The study...
Although biometric authentication is perceived to be more reliable than traditional authentication schemes, it becomes vulnerable to several attacks when it comes to remote authentication over open networks. Steganography based techniques have been used in the context of remote authentication to hide biometric feature vectors. Biometric cryptosystems, on the other hand, are proposed to enhance the...
According to the characteristics of construction project, the risk evaluation of complicated construction project is converted into the evaluation of four indexes including duration risk, cost risk, quality risk and safety risk. Establishing the fuzzy and grey correlation analysis model with the combination of the fuzzy theory and the grey correlation theory, fuzzing the judgment of specialists on...
Sustainable development analysis is the important problem in contemporary domestic and international. The analysis about sustainable development evaluation index system spreads widely in the international, this paper analyzes sustainable development index system of research results in the relevant international organizations and main developed countries. We point out the characteristics of the related...
For instance the evaluation of an Olympic problems in this paper, Firstly we collected statistical data of various factors through the establishment of the model of grey relational degree. Then quantitative analysis using the model of these factors impact on the evaluation of the object and come to affect the degree of ranking. The use of a wide range of the models in agricultural economics, water,...
This study aimed to investigate the impact of teachers' teaching quality to students' academic performance using teaching information. As students' data nested in teachers' data and it had the structure with two layers of data, this paper would use Hierarchical Linear Models. The results showed that : the effects of the four dimensions of teaching quality on academic performance and learning motivation...
This paper takes a survey to the college students, and analyzes the impact imposed by variables of purchase intention and the inter-relationship among variables such as perceived value, perceived risk and perceived usefulness. The empirical results show that perceived value is the main factor affecting purchase intention, perceived risk has no direct impact on purchase intention, and perceived usefulness...
In the modern society of which material capital is relatively abundant, human capital places an increasingly prominent role in economic growth.

This paper mainly discusses the financial data of listed 71 medicine manufacturing companies in order to establish a more accurate financial pre-warning model with the analysis of logit-model and BP-neural network, by choosing 38 comprehensive indexes which reflect the financial distress, basing on the comparison study of the financial pre-warning model.
Perceived service is regarded as an antecedent of customer satisfaction, and most of studies use linear model to estimate the effect of perceived service on customer satisfaction. However, nonlinear relationship between perceived service and customer satisfaction may exist according to previous theories. In this study, we use a bank customer sample of 2500 people and a refrigerator customer sample...
The paper first constructs two different third-party B2B e-commerce platforms according to the different ways of charging methods, and then analyses of the dynamic game between the two platforms. In the dynamic game, I establish a triangular model to describe the distribution of the seller, and on this basis, I construct a nine-cell matrix of the dynamic game to measure the results of the game accurately,...
The purpose of the study is research of an analysis method about competitive situation of the passenger car market. Firstly cluster analysis of 131 kind passenger cars on the market value, and then established panel data model of each submarket. The parameter estimation of price weight influence sales quantity to determine the degree of influence of each car in each model. Therefore the method could...
Through the analysis of the education equipment life time cycle cost concept and characteristics, In education equipment life cycle cost related data fully, known initial cost and use the phase known intermediate stage use cost conditions, respectively established the forecast model. Inadequate data can be difficult to find statistical rule, and hard to meet some typical probability distribution,...
The revenue between single-price auction and multiple-price auction can not be compared by auction theory. The paper establishes a statistical empirical model and uses the data of China's treasury auction market to examine the revenue between single-price auction and multiple-price auction. The paper has three important conclusions and the single-price auction can prevent the winner's course and collusion...
