The database audit is one of important mean to protect the security of database. In the life insurance industry, because of it master a large amount of important customer-related information, it is necessary to database audit. With the increasing of audit records and the requirement of database audit, simple means based audit log data unable to take full advantage of its intrinsic value. Thus, this...
The existed cloud data models cannot well meet the management requirements of structured data including a great deal of relational data, therefore a two-layer cloud data model is proposed by referencing the relation data model, Hierarchical data model and key value data model. In the representation layer, the concepts of composite class and composite object are proposed to represent nested data structure...
In order to explain the reason of the high underpricing rate of IPO and to judge whether there exists IPO underpricing, combined with China's specific policy system, this paper classified the IPO first-day underpricing or discount and constructed a classifier by using the decision tree modeling under the multiple influence factors. The numbers listed in this article refer to the data of initial public...
This paper based on the theory of reliability centered maintenance (RCM) techniques aimed to verify the analysis results obtained by GO-Bayes method. This paper addresses the problem of establishing Monte Carlo simulation model to simulate the braking system. Metro vehicle braking system has been selected as it is one of the most complex and high-technology systems among all devices of train vehicles...
In the 21st Century, China's mobile communications has a huge space for development. The emergence of independent of the 4th generation mobile communication technology provides an unprecedented opportunity for the development of China's mobile communications. As the world's largest telecom operator, China Mobile Communications Corporation has become the leader of promoting China's 4th generation mobile...

Railway passenger volume forecast is an important basis of passenger traffic organization, it is also the base to set railway market policies of passenger transportation. The article establishes on the basis of previous studies. After analysis the data of railway passenger volume in recent years, the author chooses the Grey Model GM (1, 1) to forecast the trend of development of railway passenger...
This paper adds to our understanding of how ICT helps to improve SC performance. We investigate both indirect and direct effects of ICT and find based on data from Chinese manufacturers that inter-organizational ICT has a positive effect via SCM-practices if the uncertainty is high. We do not find support for that relationship if uncertainty is low. No support is found for an direct effect of inter-organizational...
Being a particular structure of ancient architecture in China, a large amount of wooden architectures were inscribed on the World Heritage List. The components can be perceived as the carriers of multivariate information which will increase and update over time in a long term. To strengthen the correlation between digital information and components of architectural entities, and meet the growing demands...
By analyzing two groups of capacity assessment data, the paper obtained such data characteristics as data discreteness and frequency domain, and established an error analysis model and an error evaluation model for the above data on the basis of their characteristics. When reducing random errors, the paper compared merits and demerits of mean filters and median filters, and improved mean filters according...
The capital structure remarkably determines the debt paying and refinancing capacity of an enterprise and then influences the future earning level. In this paper, firstly we analyze the conditions and characteristics of the capital structure of 24 listed companies in Hebei Province through the related data from 2006 to 2015. Then, we examine the mainly micro-factors to capital structure by the empirical...
For inventory control strategy, the more common side strategy is centralized inventory control strategy and decentralized inventory control strategy. In this paper, multiple retailers on the supply chain are chose as research objects to study the inventory control strategy under random demand of these retailers in a multi-period inventory system. Considering the shortage costs and inventory holding...
Research on China's outward foreign direct investment has gained a lot of attention during the last two decades due to its rapid growth, though most studies ignore the spatial interdependence of outward foreign direct investment on the choice of Chinese outward foreign direct investment location. This study aims to examine the spatial links in China's outward foreign direct investment using the spatial...
