The Couner-Propagation neural networks is weak in convergent speed, will easily sink into local minimum, and its choices of initial weights and thresholds lack sound basis. So, a new optimal algorithm of neural network based on rough set was proposed. The new approach integrates the advantages of the two algorithms; it has good understandability, simple computation and exact accuracy. Then a new algorithm based rough set was put forward and used to optimize the design of neural network weights and threshold. The results of simulation show: the new algorithm can get over the insufficiency of CP, and compared with CP, greatly improve the convergent accuracy and speed, and get a good measurement result.

This paper studied the localization problem for a rescue robot based on laser scan matching and extended Kalman filtering (EKF). Scan matching method based on normal distribution transform (NDT) can avoid hard feature extraction problem by estimation of the probability distribution of laser scan data and localization can be achieved using correlation of the NDT. Based on NDT scan matching, the NDT-EKF algorithm has been proposed, which realizes fast and precise localization in rescue environment by fusing odometery data and scan matching together. The NDT-EKF algorithm has been extensively tested and experimental results show its effectiveness and robustness.

With the acceleration of urbanization, urban atmospheric pollution is becoming severe. Urban atmospheric environmental quality evaluation has aroused broad attention. This paper introduced grey correlation analysis into evaluation of urban atmospheric environmental quality and established an evaluation model. The paper selected PM10, SO2, NO2 and days of air quality equal to or above grade II as evaluation indexes. Finally the paper developed a case study on the four municipalities directly under the central government and the twenty-seven provincial capitals. The calculation results show that atmospheric environmental qualities of the 31 cities are not good, especially the four municipalities. Additionally, the paper compares results of grey correlation analysis method with that of fuzzy matter-element method. The concept of grey correlation analysis is clear and the calculation process is convenient, so grey correlation analysis is applicable to evaluation of atmospheric environmental quality.

China, with its rapid expansion of road construction and increase in the number of vehicles, road traffic accidents are becoming a serious public health problem. Driving fatigued was significantly related to traffic accidents in which the driver’s behavior contributed to the accident. This paper describes prototype driver fatigue evaluating performance by setting up various parameters that typically characterize fatigue level of the driver. This model was validated that the driver with fatigue states need longer time to reduce the decisive, sensitive and real-time competence under the protean road condition, and correlation analysis to exact parameters of drivers' reaction time.

Terrain analysis is an important job for terrain classification and geomorphologic mapping in complex terrain context. When Shuttle Radar Topography Mission appeared, enormous account of data, SRTM Digital Elevation Model (abbreviated SRTM DEM), has been sent back to earth. Then automating the analysis of this data and its interpretation represents a challenging test of significant benefit. In this study, we propose combing texture statistics and classification to interpret topography data of Sichuan Basin and landform surround and to identify constituent land-forms of the Sichuan Basin landscape. Our approach used unsupervised image segmentation to divide a landform into a number of spatially extended but topographically homogeneous objects. The objects are classified into predetermined landform classes. We have applied our technique to the Sichuan Basin and mountain surround in Sichuan Province, China. The 80% mean accuracy as a result has shown our algorithm being efficiency and acceptable.

Based on the measured deformation data series, future deformation value of deep foundation pit was predicted using Support Vector Machine (SVM) model in soft soil area. Gauss kernel function, Sequential minimal optimization arithmetic, and the parameter value of C andε were determined by testing. By using the method in example, results are shown to be in good agreement with measured data and laws reported in paper, and illustrates that SVM could perform well in solving fuzzy geotechnical engineering problem similar to deformation prediction. As another act, the method and conclusion can be considered as reference for colleagues.
