Imbalance miRNA target sample data bring about the lower prediction accuracy of SVM(Support Vector Machine). This paper proposes an SVM algorithm to predict the target genes based on biased discriminant idea. This paper selects an optimal feature sets as input data, and constructs a kernel optimization objective function based on the biased discriminant analysis criteria in the empirical feature space. The conformal transformation of a kernel is utilized to gradually optimize the kernel matrix. Through the comparative analysis of the experimental results of human, mouse and rat, the imbalance SVM with biased discriminant has higher specificity, sensitivity and prediction accuracy, which proves that it has stronger generalization ability and better robustness.

Nowadays, furniture products with local characteristics and furniture designing based on "nature" is becoming more and more popular. Black bamboo, a kind of new green materials, has the potential of being made into furniture and the Huxiang Culture which is rich in human and unique in its own region.Aim:The combination of these two can create new furniture. Methods:Based on design material of Smoked Bamboo, the paper researches the extraction of Hunan culture element method, and sums up the principles of appling Huxiang culture elements into the design of Smoked Bamboo furniture to create new furniture with flavor of Huxiang regional culture through Xiangxi tujia brocade, Mawangdui lacquer and Xiangxi diaojiao building. Result:The exploration in this field varies the species of furniture products, and meets the people’s different needs, offering reference for other regional characteristic furniture design at the same time.

The green environmental protection furniture products with local characteristics are increasingly attached attention.Smoked bamboo, a kind of new green material, has the potential to make furniture, and the Huxiang Culture which is rich in human and unique in its own region.

In this paper, the model base and objects to be identified are classed as information granules by the information granulation idea. A proper system of polar coordinates is established. The fuzzy pattern recognition problem is studied by the L-series of formation in the abstract analytic number theory. A method is given to evaluate the model base type of the information granules, which consist of massive data. Additionally,it is used to analyze the relation between process parameters and weld appearance in the welding process.

A fast remote sensing scene matching method, taking airports, oil depots, harbors and so on as research objects, is proposed in this article which is based on the SR saliency detection and frequency segmentation. Saliency detection is used to determine the candidate region where the target may exist to reduce the searching range effectively. And then, frequency segmentation is used to eliminate the frequency component except the frequency of the target to reduce the redundant information, thereby saving the computation of SIFT feature extraction and matching. A variety of experiments under different interference factors are carried out in this paper. Experimental results show that the fast matching algorithm proposed in this paper can not only maintain the validity of SIFT features under the condition of rotation, scale, illumination and viewpoint changes, but also shorten the matching time largely and improve the matching efficiency, laying the foundation for further practical application.

With the rapid development of gear, gear measurement accuracy must meet the actual demand. For this problem, through the analysis of the characteristics of gear measuring center and the accuracy requirements, using direct drive technology, a direct drive control system of gear measuring center based on Turbo PMAC2 motion controller is proposed. After testing this system, the experiment shows that direct drive technology for gear measuring center can realize good positioning accuracy, and the measurement accuracy is improved.

MIPS processor is widely used in embedded system, whose memory hierarchy has such an important effect on the performance and cost that how to design memory hierarchy rapidly is a key problem. To deal with the MIPS memory hierarchy research, we design a MIPS simulator “QtMips”. It is a GUI, Qt-based simulator for MIPS assembly language, which not only collects and analyzes real-time simulation information, but also supports fast memory configuration setting such as hierarchy setting, allocation setting, etc.

Ascertaining existing buildings of seismic capacity deficiency is the precondition of strengthening them, which is very important to reduce earthquake disaster in the future. So it is necessary to predict the seismic damage of buildings. This article is the results of earthquake disaster prediction in urban area of Langfang, which is expected to provide a theoretical basis for the buildings in Langfang to defense the earthquake disaster.

The stability of mold oscillation can directly influence on slab surface quality and operational safety in continuous casting. In recent years, the hydraulic oscillation is developed and applied as the driven equipment of mold oscillation. In the present work, based on the slab continuous caster of hydraulic oscillations, the displacement and other parameters of hydraulic oscillator are measured and the evaluation method of oscillation is studied. The displacement difference and phase difference of oscillation with sinusoidal waveform and non-sinusoidal waveform are analyzed. Especially, the dynamic characteristics of the driving force of left and right cylinders are evaluated. The results indicated that the hydraulic oscillator is quite a good device in terms of precision. The method proposed may be useful for evaluating oscillators.

A finite element method was developed to reveal the thermal characteristics of concrete with a cooling pipe, and the influence of cooling pipe on thermal field was calculated by the coupled fluid flow and solid heat transfer method. Temperature distribution along the pipeline was calculated and the mean Nusselt numbers on each section in the cooling pipe also were obtained. Numerical results show that the flow field and the temperature distribution were very complexly and the heat transfer was severely attenuated in the bend position, the outboard temperature of pipe was higher than the inboard temperature. In addition, in order to study the effect of the cooling pipe on thermal distribution, the temperature of different positions at the hydration time were compared with the no cooling results. The present results could be helpful to predict the temperature cracks in structure engineering.
