Published: October 2014

A kind of HSLA steel is designed in this experiment. The thermal stability second phase particles which would not be dissolved or aggregated at high temperature will be expected by means of adding calcium and magnesium into the steel in the form of Si-Ca alloy and Mg-Zr alloy, respectively. The effect of calcium and magnesium addition on the cast microstructure grain size of HSLA steel was analysed. The grain size of the cast microstructure in each sample was measured by the metalloscope observation method. The results show that a large amount of oxides generated from the adding Ca and Mg elements into the steel can accelerate the nucleation and refrain the grain growth, so the grains are refined. In the process of improving temperature, the oxides of Ca and Mg elements located in the interior of austenite can accelerate the nucleation and impede the grain growth. Almost every grain becomes finer after adding Ca and Mg elements. When adding 5wt% Mg, the mean grain size is the smallest, 0.712 mm, while the biggest grain size is 1.115mm in raw steel. The grain size in Mg 5wt% steel is refined by 36.1% in contrast with the raw steel. According to the adding amounts of Ca and Mg elements in experimental steel, the range of the mean grain size is from 0.712 mm to 0.975 mm.

Published: October 2014

The security evaluation for an information network system is an important management tool to insure its normal operation. We must realize the significance of the comprehensive network security risks. A network evaluation model and the algorithm are presented and adapt the hierarchical method to characterize the security risk situation. The evaluation method is used to evaluate the key nodes and the mathematics is used to analyze the whole network security situation. Compared with others, the method can automatically create a rule-based security evaluation model to evaluate the security threat from the individual security elements and the combination of security elements, and then evaluation the network situation. It is shown that this system provides a valuable model and algorithms to help to find the security rules, adjust the security measure, improve the security performance and design the appropriate security risk evaluation and management tools.

Authors: Fang Zhen Cheng
Published: October 2014

Along with the completion of HGP (human genome project), huge amounts of genetic data constantly emerge. Research suggests that genes are not in independent existence and the expression of a gene will promote or inhibit the expression of another gene; if the expression of a gene makes the biochemical environment of cells changed, the expression of a series of genes will be affected. In order to get a better understanding of the relationship between genes, all sorts of gene regulatory network models have been established by scientists. In this paper, a variety of gene regulatory networks are first introduced according to the process of this subject research, and then the most basic network (i.e. Boolean network) is emphatically analyzed, and then a new method (i.e. Boolean network based on the theory of circuit) to describe Boolean network is drawn forth. After the shortcomings of the Boolean network proposed in the past are analyzed, a simulation circuit Boolean model is established using EDA technology in order to improve the Boolean network.
