Traditional software metrics have the limitations for large-scale software system, so we construct the static structure model for large-scale software by structural mapping and visualization, propose a integrated metrics set based on complex networks parameters according to the perspective of software engineering. The feasibility and validity of the metrics were testified through statistical analyzing...
In a multi-storey transport hub under ground, different platforms belong to different traffic line. To monitor and control the equipments situation, especially for the alarm equipments, information in multi-storey must be shared and linkage. This kind of information configuration comes down to the integrated management system in the whole city. In this paper, an information transferring model is presented,...
Regarding the inconstant requirements of e-business, in this paper, we propose to use distributed intelligent middleware based on multi-agent systems (MAS) to implement integrating workflows of existing systems for a more efficient and flexible integrated e-business platform. The formal rules of workflow integration processes for existing systems have been put forward by applying various theory and...
Correct recognition of the lines is essential for technical drawing understanding. Automation solution is quite difficult due to the limitations of machine vision algorithm. In order to promote development of better technology, according to the fast and high-quality clustering algorithm particle swarm optimization (PSO), a new fast and high-quality line clustering algorithm present in this paper,...
At present many cities in our country have massive plans in constructing comprehensive transportation hubs. To realize security operation of it well, the paper proposes establishing "the regional security monitoring center" in the hubs. It can realize different complex transportation supervisory system's information sharing and the seamless connection. Firstly, the paper discusses on the...
Analyzing the distance between the location and the new location, we conclude inertia weight method which linearly decreases from 0.9 to 0.4 has the powerful local search ability on Schafferpsilas F6 function. In order to improve the balance between local and global search ability, the novel adaptive PSO algorithm which evaluates a reset function to control the inertia weight value is proposed. Once...
To enhance the performance of global supply chain is one of the important competitive strategies for many businesses. The performance evaluation of suppliers within chain has become an important subject for impacting the efficiency of chain. It is not realistic to evaluate the performance by just one short period of time. To integrate the data across years would be a better way. Moreover, the suppliers...
This paper performs systematic comparative studies on weighted methods including weight C4.5, weighted SVM and weighted rough set with traditional C4.5, SVM and rough set for credit scoring. The experiments show that the weighted methods outperform to the traditional methods when the methods are sensitive to the class distribution.
The Truck backer-upper problem is a typical problem in the domain of fuzzy control and being a highly nonlinear control problem. This paper present control strategy of fuzzy control based on the Line of Sight (LOS), and according to the experience of driver, and simulation experiment for the problem of backing up truck, simply the fuzzy control rule, the control of this fuzzy controller is successful...
This paper focuses on the adaptive control of a class of nonlinear systems with unknown saturation constraint imposed on the control input. By constructing neural network, a observer-based approach is developed using nonlinear output feedback techniques.The simulation example is given to illustrate the effectiveness of this method.
Singular rough sets is defined by R-element equivalence class, which has dynamic characteristic. By engrafting, crossing, and penetrating between information security theory and singular rough sets, singular rough decision is given, furthermore secure transmission of decision conclusion is also presented in this paper. The fusion and share between singular rough sets and information security theory...
In the present paper we establish the global approximate controllability of the parabolic-elliptic equations,which are governed in a bounded domain by a pair of controls:the traditional internal either locally distributed or lumped control; the lumped control entering the system as a time-dependent coefficient. The motivation for the latter is due to the well-known lack of global controllability properties...
The tank system is a typical industrial system model, which is abstracted from water level system in process industry field. Generally it has the characters of time lags, non-linearity and difficult to build mathematics model etc. For some deviant problems often appeared during the control of the water tank system, this paper adopts fuzzy decision strategy to deal with them. The simulation effects...
The notions of the (strongly) practical stability in probability and in the pth mean, are introduced for some large-scale stochastic systems with Markovian jump parameters and time-varying delays. Sufficient conditions on such practical properties are obtained by using the comparison principle and the Lyapunov function methods.

Magnetic valve type controlled reactor (MVCR) is the electrical equipment which shows some strongly nonlinear properties when working and its performance is influenced by its turn ratio. Some irregular phenomenon, for example, the mutation of ultimate dynamic state, the uncertain electromagnetic or mechanical noise, may occur under the condition of the improper value of turn ratio. In order to study...
