This paper proposes a novel high-accuracy stereo matching scheme based on adaptive ground control points (AdaptGCP). Different from traditional fixed GCP-based methods, we consider color dissimilarity, spatial relation, and the pixel-matching reliability to select GCP adaptively in each local support window. To minimize the global energy, we propose a practical solution, named as alternating updating...
The paper builds the influential factor model of virtual community knowledge sharing behavior from the four dimensions. By using structural equation model, the paper makes an empirical research on the key factors of promoting the college students' knowledge sharing behavior in the virtual community and the impact of knowledge sharing behavior of virtual community members on the community loyalty.
With rapid development of internet, more and more consumers choose to shop from different channels, such as offline channel and online channel. Some consumers prefer shopping through offline channel because they want to experience the products' quality in person, while other consumers would like to shop online because they care more about the efficiency of shopping. There are several factors that...
This paper introduces and discusses an evaluation method of new data sources for reliability purposes. Through the continuously increasing amount of electronic control units (ECU) in capital goods, usage data may become available to improve reliability practices and maintenance processes. Such ECU-data sources may be captured and correlated in numerous ways and thus result in confusingly large matrices,...
The majority of reliability modeling techniques assume systems and their components exhibit a single mode of failure. However, many systems including hardware are susceptible to two or more distinct failure modes. Previous research on two failure mode systems derived analytical expressions to determine the number of components that will maximize system reliability or minimize system cost. However,...
Considering that the amount of money spent for implementing digital library is very high, it is therefore very crucial to evaluate its effectiveness. Since the implementation of digital library in the University of Tehran, Iran, no attempt has been made to evaluate its effectiveness. Against this concern, a study was carried out to investigate the effectiveness of the digital library from the user...
This paper presents a novel method for calculating the unstable equilibrium point (UEP) for a two-bus system using holomorphic embedding (HE). The method is guaranteed to find the UEP solution. The focus of this paper is to prove mathematically that if a UEP solution exists, the method is guaranteed to arrive at that and only that solution and if no solution exists, then such is indicated by the oscillations...
In applications of permanent magnet, the calculation for magnetic flux intensity is of primary importance. The magnetic dipole is simple mathematic model which is used frequently. However, it is required that the evaluation points are far from the magnet; otherwise, the measured data is wrong. An approach of calculating the magnetic flux intensities at those points which are very close to the magnet...
Few researchers conducted empirical study on assessing competitive advantage in previous studies. In this paper, we try to establish an evaluation model of competitive advantage based on customer satisfaction and customer value. Then we conducted a survey of 37 durables manufacturers and 9250 samples in China to calculate the model. The results show that customer value exerts significant effect on...
High schools have rapidly adapted computers in their administration, management and academy. School management uses papers and computers as tools to store the administrative and management data. However computers are not used to analyze data and output information. Therefore, e-School Management System (e-SMS) is developed to facilitate teaching and administration staffs to manage school activities...
We present the results of a simulation to assess the optimal design characteristics of rainwater harvesting systems to be used in a semi-arid region of the United States. The simulation leverages a stochastic, non-parametric rainfall generator based on 64-years of daily historical data. The assumption of non-stationarity of rainfall is also thoroughly investigated for this paper. Of specific interest...
In this paper, we propose a novel framework WSCRec, in which historical information (i.e., execution logs) are utilized to facilitate the process of Web service composition. According to the execution logs of composite services, appropriate services which have been proved to be more reliable and robust and have higher probability to fulfill users' demands are located.
The paper investigated the impact of psychological empowerment on quit intention and their mediators in post-services. By surveying 198 frontline post-service employees, we found that competence and job meaning have significant impact on quit intention, meanwhile competence exerts its influence through raising organization commitment. Job meaning exerts its impact on quit intention through organization...
We evaluate the average growth rate of the low-density generator-matrix (LDGM) code ensembles by applying the statistical-mechanical approach, which is called as the quenched average growth rate. In the existing analysis, the annealed average growth rate, which is the growth rate of the average weight distribution, has been evaluated. We explicitly show some examples of the difference between the...
The risk management group at the South Texas Project Electric Generating Station (STPEGS) has successfully developed a Preventive Maintenance (PM) optimization application based on a new mathematical model developed in collaboration with the University of Texas at Austin. This model uses historical maintenance data from the STPEGS work management database. Robust statistical analysis, coupled with...
A passive universal image steganalysis method is proposed that is shown to be of higher detection accuracy than existing truly blind steganalysis methods including Farid's and the WAM. This is achieved by improving some weaknesses of Farid's steganalysis scheme in feature extraction, that is, instead of deriving an over-determined equation system for each sub band of the wavelet decomposition, the...

As the environment and customer needs become more and more instability and complex, Flexible manufacturing capability plays a very important role in enhancing firm's Competitive advantage and performance. Based on previous studies, this paper makes an explorative study of the relationship among Flexible manufacturing competence, Competitive advantage and firm performance, then the relationship among...
Employing survey method on internet consumer, this article finds internet consumer's participation, especially behaviorally and affectively, significantly affects electronic service perceived quality. However, personality participation, another important factor, doesn't fit our data set and has no significant impact on perceived quality.
