Products arranged in the same zone usually have some spatial correlation, function relation and the impact of environmental stress, which usually causes coupling effect with other products in the same zone. This kind of coupling effect affects products' quality, and may influence the veracity and comprehensiveness of the quality analysis. To solve this issue, starting from changing the traditional...
Recommendation is an important problem in the traditional field of data mining. As a consequence, various kinds of algorithms have been proposed in the last few years to improve the recommendation performance. However, many of them overlook users' rating behaviors. In this paper, an improved recommendation algorithm with considering users' habits and rating behaviors will be proposed. Firstly, calculate...
Utilizing network traffic scheduling to improve the energy efficiency of smartphones has been studied extensively in the past few years. These studies usually take certain approaches and make some assumptions concerning traffic predictability, regardless of whether these assumptions hold or whether the approaches have been studied before. In this paper, we conduct an analysis of existing work to find...
This essay takes 199 listed companies between October 23, 2009 and December 31, 2011 as samples to study the relationship among intrinsic value of the company, investor sentiment and the IPO under-pricing in the growth enterprise market. Results show that the intrinsic value of the company, investor sentiment and corporate governance is the main factor to affect GEM IPO under-pricing, while industry...
In order to address the existing problem that only the measurement of uncertainty is provided for the tolerance results, a calculating method of sphericity error evaluation standard uncertainties studied according to new Geometrical Product Specification and Verification(GPS). Sphericity error evaluation mathematical model based on minimum area method is raised. Sphericity error value is obtained...
In the strategic context of enterprise information technology, a reasonable and scientific assessment of the enterprise value-added has become the key issue of the enterprise development. Taking the cooperative effect as the core, the implementation of enterprise information changes the value of the enterprise system to a certain extent. From the perspective of the value chain, information-based business-to-business...
This study examined the effect of trust on counterproductive work behavior(CWB) in organization by correlation analysis and SEM. Individuals' trust in their coworkers and supervisors are negatively related to CWB directed at the coworkers and supervisors, whereas trust in supervisors and top managers have no significant relationship with CWB directed at the organization.
This study aims to quantify the relationship between field Black soil hyperspectral reflectance and soil moisture at different depth. The stepwise regression predicting model of soil moisture at different depths was built with the spectral derivatives as independent variable, and the models were evaluated with root mean square error (RMSE) and determining coefficient. The results are as follows: (1)...
