With respect to decision table, especially the inconsistent ones. On the basis of equivalent partitions, This paper quantifies the elements in the same class deduced by condition attribute belonging to different decision attribute classes, generates the discernibility matrix and measures the indexes of attribute significance reasonable, and then uses these formulas as heuristic information to design...
In this paper, regards room No. of ward building as an example. specific study of the medical service robot on the principle of building identification. The whole process is divided into image preprocessing, image segmentation, character segmentation, character recognition, And raise an improved algorithm about character recognition based on BP neural network, which is proved in practice.
A Web intrusion protection mechanism based on platform conversion is presented in the paper. According to Web service, intrusion attack has the relevance of target platforms and web application service programs. Aiming at Windows platform, IIS attack will not be successful when the target is Apache to Linux platform, and vice versa. The presented Intrusion response mechanism uses two servers to load...
In order to improve the accuracy and efficiency of weed recognition, an identification method based on ant colony optimization (ACO) algorithm and support vector machine (SVM) is proposed. Firstly, shape feature parameters are extracted from the plant leaves after a series of image processing such as threshold segmentation, smooth processing and edge detection etc., and five geometric parameters and...
Mechanized infantry is an essential part in the simulation system of military operation, but because it is difficult to simulate the control of virtual soldiers and behaviors of person, nowadays a lot of land war simulation systems still mainly focus on entity simulation in weapon platform level, lack the simulation of infantry entity. According to features of human vision, environmental perception...
Quantum-dot cellular automata (QCA) is a promising nanotechnology which has potential applications in future computers. Its advantages such as faster speed, smaller size and lower power consumption than CMOS are very attractive. Universal logic gates have stronger function than traditional logic gates. This paper begins with a review of QCA,i.e. basic principles of QCA, QCA logic devices and modular...
The intensification mechanism and diversification mechanism of Basic Particle Swarm Optimization (BPSO) algorithm were analyzed, and the precision problem of BPSO was discussed. Then a new hybrid PSO algorithm was set up, and the Variable Dimension Greedy Randomized Adaptive Search Procedure (VDGRASP) was designed to combine with BPSO. Two parameters of the hybrid PSO, SubDNum and PerturbScope, were...
In order to evaluate bridge structures' bearing capacity quickly, the frequency coefficient method was proposed. The formula between frequency coefficient and deflection coefficient was established through stiffness based on theory, and it was revised by the statistics results of 173 samples. The rational range of frequency coefficient was built by regression equation based on the confirmed range...
A effective approach to global motion compensation and moving object extraction is proposed. Firstly, feature-block detection and search-matching algorithm are used to attain background motion vectors of global image. Then, once the global motion vectors are robustly estimated, relatively stationary background can be almost completely eliminated through the registration difference algorithm. Finally,...
Due to the decline of the viability and battle effectiveness of the electronic countermeasure armored vehicle caused by intense infrared radiation (IR), the temperature model is built for the IR characterizations of moving target. While taking the effect of radiation, convection and heat transfer into consideration, the mathematic description and simulation of the temperature model are carried out...
With the rapid development of information technology, multi-sensor information fusion research has been made great progress, currently there are Bayesian test, the voting method, fuzzy sets, neural networks and other methods algorithm being used in multi-sensor information fusion commonly. However, there are many shortcomings which are difficult to overcome in the process of fusion by these methods,...
The importance of the activation functions in ANN is emphasized. A new ANN modeling method is proposed based on constructive algorithm and GP. This method can be used to realize the automatic optimization of the ANN's net structure and the activation functions. As a result, the ANN's constructure and generalization capability is greatly improved, it's characteristic is better than the M-P feed forword...
As for the limitation of static information verification in the current remote attestation models, this paper presents a novel remote dynamic attestation model named BTRAM (Behavior based Trust Remote Attestation Model) which is based on the user behavior trustworthiness and attribute-based access control. In this model, a verifier proxy is used to verify the requestor. Meanwhile, the executive process...
The traditional wave superposition method has the merit of higher computing velocity and higher calculation precision. But it relies solely on mesh geometry, and it cannot accommodate fast shape changes in the design stage of a consumer product or machinery, where much iteration of shape changes is required. And a new approach for representing geometry is introduced by constructing a uniform lattice...
This paper introduces an intersection accident prediction model by applying BP neural network, which can well structure the corresponding function of intersection traffic conditions and accident form, and the paper trains and predicts the model with 197 intersection data, the test results show that the prediction accuracy can reach up to 89 percent. The paper establishes an identification method of...
The influence of flexible body and legs of lander, plastic deformation of lunar regolith on landing impact performance of lander is rarely researched, and literatures about using transient dynamics to analysis soft landing impact performance of lunar lander are also less. In this paper, a new idea and method for research on landing impact performance is presented. Flexible models and transient dynamics...
Descaling nozzles used for generation of high-speed water jets are key components in high-pressure waterjet descaling system. The jet quality and the jet impact performance of the nozzle have great effect upon hot-rolling steel billet descaling. According to work conditions of waterjet descaling process, a jet impact performance test system for nozzles was developed. The jet impact force distribution...

Most universities today have large and complex structure and activities (Multiversity) and, exist in them, huge amount of data resources. But until now, there is no mature method to collect and process these data to meet the need of information system application. Some systems used in separate sectors can not provide effective information for management decision and meet the needs of public inquiries...
