On behalf of the Program Committee and the Organizing Committee, it is a great pleasure for us to welcome you to the International Conference on Systems and Informatics (ICSAI 2012). The demands of systems and informatics in our daily life have been constantly increasing, as more and more computer applications were built in past decades. Great efforts have been made to improve the state of the art...

Soft starter is the equipment which can control AC motor startup safely. It can not only effectively eliminate the impact on the state grid and the load and torque in the powertrain of the motor, but also improve service life of the AC motor. For these reasons, soft starter is widely used in our working which is related closely with induction motors. Above all, in order to control the AC motor starting...
The control of Multi-tank Liquid-level System is both a typical multivariable control problem and a typical problem that is used to verify conception and method of multivariable control. In this paper, a decoupling controller matrix is designed based on the complete decoupling method of feedforward compensation. For the decoupled objective function, the parameters of PI controller are tuned using...
It is crucial to get human hand information for hand gesture recognition tasks. However, at present, people can not still get a perfect hand segmentation or localize hand accurately especially under complex conditions. Therefore, it is necessary to develop robust and effective methods for detecting human hand accurately. In this paper, we propose a new method for hand detection. We present an extended...
According to the entropy theory, information never occurs spontaneously at the expense of energy dissipation in the process of dissemination and transformation by taking into account of the impact of the complex system. At the pan-media era of media convergence, we have to take into consideration introduction of negative entropy to maintain stability of the communication system, so as to alleviate...
Pulse repetition interval (PRI) is an important parameter in radar signal sorting. In this paper plane transformation technique is applied to radar signal sorting. Firstly we derive the plane transformation characteristic curve of a periodic signal, followed by an improved extraction algorithm. Simulation results show that the extraction algorithm transforms the characteristic curve correctly after...
With the development of research on the complex networks, dynamic evolution of network structure has become a hot issue for the current study. In this paper, we completed the dynamic evolution analysis of network structure through three steps. First of all, by the social network analytic method, the paper described the dynamic change of real network model's three basic properties, namely, degree distribution,...
Geological heritage, the non-renewable geological natural heritage, is formed by inside and outside geological forces and is a special natural tourism resource with educational function. Using the Delphi and AHP methods to evaluate the geological heritage can make up for the shortcomings of AHP, the choice of factors and the determining of weights will be more scientific and objective. In this paper,...
By analyzing the principle of the quasi-optimal satellite selection algorithm and the fast satellite selection algorithm, this paper puts forward a new satellite selection algorithm. In order to increase satellite selection speed and improve satellite selection effect, the new algorithm makes use of two satellites' comparability and the distribution characteristic of satellites with high or low elevation...
The bushfire may seriously effected the neighboring transmission line. Every year a large number of transmission lines tripping accidents happened due to fire. As the transmission line distributed throughout the areas, and the range is wide, and in most areas it's given priority to the hill terrain, seriously affecting the efficiency of the traditional inspection method for transmission line, and...
Software reliability testing (SRT) is one of the most important technologies to evaluate the levels of software reliability. The key of the SRT is to model the actual usage of the software. Traditional operational profile is fit to the software in which the operations are obvious. But some software, such as software in Autonomous Control System (ACS), the operation is difficult to define and the traditional...
This paper, the robust stability problem of dynamic interval systems with multiple time-delays is considered. Firstly, a kind of equivalent description of the interval matrix is presented. Then by using Lyapunov stability theory and matrix measure approach, several simple sufficient conditions of robust stability for dynamic continuous and discrete interval systems with multiple time-delays are obtained,...
Model-Driven Software Development (MDSD) techniques are increasingly used in large development environments. This paper proposes an extended executable business model named exBM to ensure system modeling for both web and C/S applications. The metamodel of exBM is presented to sufficiently describe both the structural and behavioral properties of applications. A schedule model is added to exBM in order...
Using abstract syntax tree as the basis of static analysis of Java program have many difficulties. The paper defines a XML data structure for Java bytecode, instead of abstract syntax tree as the basis of static analysis of Java program. The XML data structure is formally defined by using Java bytecode specification and XML schema specification. Comparing with the method that converts Java source...
In recent years, rapid warming of Arctic has made the Northwest Passage navigation possible. In this paper, we roughly studied features of variation of sea ice's concentration during the summer season, June, August and September, using AMSR-E sea ice concentration product with the resolution of 6.25 kilometers from the year 2002 to 2010. By studying the variation, we got deeper understanding of the...
In this paper, we put forward a modeling method for the intraday volume series that exhibits W shape structure and heteroskedasticity. Firstly, we take the averaged values of historical intraday volume as the periodic component of volume. Then we choose proper mean-variance models to simulate the volume series removed intra-daily periodic trend. Finally, we use the period-mean-variance model selected...
An appropriate selection of kernel function and its parameters is very important for the relevance vector machine (RVM) to achieve a good performance. To overcome the limitation of RVM with single kernel, a multi-scale RVM classification method based on intelligent optimization is proposed. Multiple Gaussian kernels are combined by linear weighting and the kernel parameters are tuned by quantum-behaved...
