Formal Concept Analysis and Rough Set Theory offer related and complementary approaches for data analysis. Many efforts have been made to compare and combine the two theories. In this paper, a transformation design is proposed from a partition to concept lattice. This method selects the max-covered attributes decision-set from the equivalence classes to assist generating the new concepts and an index-tree is applied to control the process of the lattice-building. This algorithm indicates a deferent aspect of the relationship between the Rough set and Concept lattice.

Schema matching is important for schema integration and thus has got great attention. In this paper, we present an ontology-based algorithm to match a larger number of interface schemas, which can hand both simple and complex mappings of attributes. Firstly, construct a core ontology and the semantics of concepts in the core ontology can be enriched during schema matching. Secondly, design the ontology-assisted schema matching algorithmic for deep web query interface. Lastly, capture the matching relationships between source schema and target schema using domain-specific ontology. During the schema matching of deep web entries, ontology is the ″bridging″ which is used to obtain the mapping relationships between different query interfaces. Experiment result shows that this method is feasible and effective. Copyright © 2010 Binary Information Press.

With the rapid development of science and technology and with the continuous improvement of people's safe sense, Video Surveillance System has already been widely used in several fields, such as military affairs, production, daily life and so on. As the most basic and important part of Video Surveillance System, the detection of moving objects has been paid more attention. Therefore, this paper mainly implements and analyzes several commonly used methods for moving object detection in Video Surveillance System, such as temporal difference, median filtering and Single Gaussian model. The advantages and disadvantages of the methods are pointed out to help people make choices in applications.

By using the distributed thought developed a hierarchical framework for the operational command and control system, the framework implements the top-level structure, the network architecture and the distributed transaction processing services. Message distribution mechanism is applied in the framework, which ensures the scalability of the framework's function. Compared with the previous command and control systems, command and control system based on this framework has the following advantages: flexible, easy to expand, strong fault tolerance and coordinated operations and so on. The framework has important practical and reference value.

In order to get rid of the limit of traditional methods and provide a decision making reference for the supervision of securities organizations and the risk control of investors, A novel model based on SOM2W network (SOM with 2 winners self-organizing map) is proposed for assessment financial performance of the listed companies. In addition, a tabu-mapping method is proposed to avoid that the same output node is mapped by more than one input. The financial indexes reflecting the whole performance level of companies are used in the simulated experiments including earning per share, net asset yield and main profit margin. Simulation results show that the proposed model is feasible for assessment listed reality companies. It could provide an effective approach for analyzing and selecting listed companies, which has good potential in the financial field.

MicroRNAs are one type of noncoding RNA that regulate their target mRNAs before mRNAs are translated into proteins. Although it has been demonstrated that the regulation is through partial binding of the seed region of a miRNA and its targets, the mechanism of this process is not fully discovered. Some biological experiments have shown that even perfect base pairing in the seed region does not always guarantee the down-regulation of the targets. It has been suspected that some other characteristics of mRNAs may facilitate the regulation. An earlier study (1) has identified five additional features beyond seed matching that seem to significantly affect repressions. However, the observation that evolutionally conserved targets have shown significantly more destabilization comparing to nonconserved targets with the same score using these five features leads to the suspicion that additional features remain to be discovered. This motivates our study to identify additional features that may differentiate down-regulated mRNAs (positive set) from those not down-regulated ones (negative set) provided both sets have perfect seed matches with miRNAs. Our first attempt to search for different sequence motifs around seed site regions in the two different sets is not successful. We further construct a set of 18 sequence/structure features based on domain knowledge and evaluate them individually and jointly. By employing feature selection techniques in combination with several classification methods, we have been able to identify a subset of features that may facilitate the down-regulation of mRNAs. Our results can be incorporated into target prediction algorithms to further improve target specificities.

[ Objective] To study the germination characteristics of Hordeum brevisubulatum seeds in the Songnen Plains of China under different conditions and find out the optimum conditions for germination. [ Method] A total of five variable temperatures including 15/25, 20/30, 15/30, 20/25 and 15/20 ℃, five concentrations of sodium chloride solutions including 0, 75, 85, 95 and 105 mmol/L, and five concentrations of CS2 strain （the A values were 0, 0.500 0, 0.050 0, 0.005 0 and 0.000 5, respectively） were studied by orthogonal experimental design. [ Result] The germination rate, germination energy and germination index were significantly （ P 〈 0.05） affected by the temperature and sodium chloride concentration, but rarely affected by the CS2 strain concentration. Moreover, the germination rate, germination potential and germination index were all decreased with the increasing of sodium chloride concentration. [ Conclusion] The optimal germination conditions of Hordeum brevisubulatum are as follows： temperatures of 15/25 ℃ and 15/30℃, 0 mmoVL of sodium chloride concentration.
