Complex networks are a useful tool to study WSNs. In this paper, we introduce the concept of overpayment from complex networks and propose an optimal path routing algorithm to solve the random problem after reaching the equilibrium. Finally, we present the simulation of our algorithm.
Matlab is the Math Works company business mathematics software, mainly applied in engineering design, calculation, the control signal processing and communication, image processing and signal detection, modeling design and analysis, etc. In the above application fields Matlab has powerful functions, in order to cultivate students' scientific spirit and practical ability and innovative consciousness,...
As the random feature of traffic accidents and there are many factors including qualitative and quantitative ones, accident rate was selected as microscopic predict objective after four traffic accident indexes and accident rate were analyzed. Seven factors, including driving years, number of lanes, radius of horizontal curve, longitudinal grade, road surface status, type of intersection and width...
The rule based expert system model, structure and sand prevention method, sand control design, the evaluation of sand control in detail, and the expert system based on rule and sand control technology of combining rule based expert system, puts forward the comprehensive analysis and evaluation of sand control system, and successfully applied in some oil field.
The attack angle and its angular rate, the aerodynamic forces and aerodynamic moments of a super maneuverable aircraft are influenced a lot by wind field. The flight control system has the ability to overcome the influences of the wind field is an important guarantee to the safety of the flight. Firstly, the nonlinear dynamic model of a super manenverable aircraft is established, and the processes...
Taking advantage of neural network back propagation algorithm and Takagi-Sugeno fuzzy inference system, a kind of pilot model is developed based on adaptive neural fuzzy inference system. A longitudinal man machine systems in air-refueling condition is simulated. The simulation results show that the model presented by our scheme is reasonable and can be used to illustrate the handling behavior of...

The main components of the inventory control system are analyzed. The dynamic inventory control model of vulnerable articles is built by focusing on the characteristics of the vulnerable articles, introducing the lost time and loss factor of articles to calculate the inventory loss cost and on the condition of considering the bulk price discount and safety inventory, etc. The model has been verified...
Nowadays, with the rapid development of the logistics industry, the high-efficiently automatic picking system in modern distribution centers have brought forward tougher requirements to the replenishment operations. But most experts are still focusing on the study of picking system. Based on former findings, this paper firstly analyzed the mode of the replenishment operation and departed it into two...
This paper uses the support vector machine (SVM) algorithm to study the prediction of corn production in Heilongjiang province, forms the sample set with the 1991-2008 data in Heilongjiang province, and set up the SVM model between factors and corn production. Use SVM on the input and output data for training and learning, approximate the implied function relationship by historical data, complete...
This paper presents a comparative study between Partial Least Squares (PLS) method and support vector regression (SVR) in modeling the relationship between the near infrared spectra (NIRS) and the polysaccharide contents in Cordyceps gunnii mycelia powder samples. Both of the models were optimized by selecting the suitable spectra preprocessing methods and the best modeling parameters. And then the...
This paper has compared synthesis load model and difference equation model, the research analysis showed that synthesis load model has better accuracy and is more suitable to simulate real load, which has a well-defined physical meaning. Finally, the research conclusion is demonstrated by the simulation results.
A traffic condition identification method based on regional road network was put forward in order to accurately identify real-time traffic condition and distribution of road network. On the analysis of the traffic status parameters of the intersection and section, the road network model was built. With the average travel time as the traffic parameters of regional network, traffic condition analysis...
Based on the injury estimate system of vehicle occupant in emergency brake is established. The vehicle occupant restraint system model is established based on software called MADYMO for front impact simulation, the system consists of body, safety belts and a dummy. After adjusting the model, occupant head and chest injury curves and injury values such as HIC, T3MS and Thpc are got, which are close...
