With the widespread application of microblog, it has become a platform for people to publish their interest topics, to express personal feelings, to participate in a centralized discussion. Aiming at the tracking problem of hot events in microblogs, this paper proposes a new tracking method of hot events...

With the increasing number of undergraduates, the security problem of campus has been greatly drawn attention from the education world. This paper is based on the theories of campus security management combined with practical situation. It summary the database design, function design and spatial data...

In this paper, a modified K-means algorithm is proposed to categorize a set of data into smaller clusters. K-means algorithm is a simple and easy clustering method which can efficiently separate a huge number of continuous numerical data with high-dimensions. Moreover, the data in each cluster are similar...

MATLAB is a kind of software which has powerful computing capabilities. This paper used the MATLAB software to computing the gray GM(1.1) prediction model, and establish the gray GM(1.1) prediction model based on historical data of production of wheat in Shandong Province. Through residual test, the...

This paper analyzed and generalized the content and characteristics of interactive waiting, which should care more about user’s psychological sense about waiting time. Based on the discussion, the article advanced several principles to help designer to do user-centered interaction design, such as put...

Data grid is the fundamental work of graphics drafting, scientific computing and the realization of spatial analysis. The paper uses dynamic grid system and assigning technology of spatial data to implement interoperability of multiple-sources data. Assign grid system has multi-attributes, which applies...

Given that the centralized-servers-technology-based network communication software like QQ and MSN are high on cost and limited on users’ control right, this thesis presents a designing scheme of the distributed-servers-technology-based network communication software. The design follows consistently...

Since the stock market has become an important component of financial system in one country, it is very critical for the regulator to keep the market stability and avoid the illegal behaviors in order to maintain the national financial security. This paper analyzes the regulation of inside trading in...

The Hatch filter is a code-smoothing technique using integrated carrier phase observations. It is an averaging filter that can smooth pseudorange measurements with continuous carrier phase. It is well known that if the smoothing window is an averaging constant, the filter diverges because of opposite...

This paper analyze different aspects of factors that affecting passenger volume of Beijing subway, then select fifteen key factors from four aspects: internal structure of the urban rail transit system, urban demographic features, economic development and urban transport structure. Firstly, SPSS software...

An imaging approach based on the Double Frequency Slope (DFS) waveform in multiple-input and multiple-output (MIMO) synthetic aperture radar (SAR) is presented in this paper. Firstly the DFS waveform’s range-Doppler domain’s features after in range direction is analyzed based on principle of stationary...

Under the currently trend of the library collection quantity increasingly, the book disordered problem became more common which caused the reader too hard to find a book that they want. To solve these problems, this paper design the accurate location algorithm based on RFID intelligent bookshelf, and...

This paper considers the use of insertion of idle time in the unrelated parallel machine scheduling problem with an objective of minimizing the sum of earliness and tardiness. An effective and efficient mixed integer linear programming formulation is proposed. For comparison, two models where the use...

This The autonomous mission planning becomes a trend to satellites. For this reason, the autonomous mission planning system of satellites is reviewed in this paper. This review can guide the researchers to do more works of the autonomous mission planning system of satellites.

Based on brief introduction of the functions of three text mining software named as SAS Text Miner, VisualText, and TRS CKM, this paper comparatively analyses the three text mining software from three aspects of features embedded in data preparation, data analysis and result reporting. It is found that...
