In view of the problem that attribute value is given in the form of interval number in the fuzzy multiple attribute decision making, comprehensive ideal scheme decision method based on set pair analysis is adopted to make decision. The method extend the application range of set pair analysis from accurate real number domain to fuzzy interval number field. In the condition of uncertain circumstances, set pairs between two interval numbers consists of every scheme and positive ideal scheme and negative ideal scheme are analysed. Connection numbers are obtained and fuzzy multiple attribute decision making is implemented according to the criterion y. Simulation results show that the proposed method is an effective tool to handle uncertain information and solve the fuzzy multiple attribute question.

This paper presents a novel wireless sensor network data imputation algorithm based on minimized similarity distortion (MSD). Firstly, the MSD algorithm considers attributes of the sensor datasets besides spatial and temporal to achieve complete dimensional data segmentations. It improves the problem of ignoring both the relationship of different attributes and the similar details in local data area. After that, it computes the distance between data units to get the k-nearest neighbors of the data units with missing values. For every missing value, MSD gives K preliminary predictive values with linear regression. Finally, MSD take the weighted K values as the final predictive values. Experimental results on real public wireless sensor data sets are provided to illustrate the efficiency and the robustness of the proposed algorithm.

The symmetry breaking bifurcation of a sine map is discussed when the control parameter in the sine map is chosen as a bifurcation parameter. Based on the sine map, the bifurcation points can be derived by the iterative map. Then, the stability of the system is enhanced by employing a cubic and a linear chaotic controller to exactly control the locations of the bifurcation points. Moreover, the universal constants of the chaotic system have been obtained by numerical simulation. The validity of the theoretical analysis is proved by the diagrams of bifurcation and Lyapunov exponent.

To decrease the influence of friction on control accuracy of electro-optical tracking servo system, the fuzzy sliding mode control (SMC) with variable universe was put forward. Firstly, based on the LuGre friction model, a sliding mode controller with power reaching law was set up, Then, to relieve the chattering problem, the fuzzy method with variable universe was used to adjust the plus of the sliding mode controller, Finally, the simulation experiment was put up to compare control accuracy of these two controllers. The simulation results show that the fuzzy sliding mode controller with variable universe not only improves the tracking accuracy, but also relieves the chattering problem substantially.

This paper analyzed the causes of highway traffic accidents on foggy days, and concluded that the main cause is driver's failure to keep enough safe driving distance. A safety transportation mathematical model was established, taking safe distance and running speed as the major parameter. The adoption of laser ranging device in measuring distance, combined with the sensor network control warning method on highway guardrail ensured vehicle anti-collision in foggy days. The vehicle detector sensor was equipped at guardrail intervals, which were connected with controller using conducting wires, forming a closed physical network. This dual detector constitutes a valid intelligent control system for traffic safe distance. The practice shows that it is an effective intelligent traffic safety distance control system which has good real-time performance and accuracy and sends a timely alarm in dangerous cases.
