In this paper, a multiple piecewise-linear function is constructed for generating multi-scroll chaotic attractors from the sixth-order Chua system. This approach has been verified both in theoretical analysis and computer simulations.
Most of the traditional researches of the robotics based on multi-sensor data fusion concentrated on the problems of autonomous navigation and localization, few of them involved the target tracking. The existing fusion method based on the network time-delay applied the traditional synchronized fusion algorithm directly, therefore, it had led many problems, such as the information waiting, resources...
Based on the models of image motion blurring and restoring, the element of image blurring caused by rotation motion is analyzed. Three widely used methods for the identification of blurred extent from the rectilinear motion blurred images, Fourier transform, error-parameter curve, and autocorrelation, are introduced in rotation motion blurred image analysis. The feasibility and effectiveness of the...
Dynamic water surface simulation is an important part of simulating natural scene. Ben Humphrey used projection texture mapping, depth texture and mobile texture to render dynamic water surface and got a good result. In this paper, an improvement method will presented for speeding up its rendering speed and enhancing the rendering effects. It uses a viewpoint correlative method to replace depth texture...
Computer science and technology are constantly changing, which results in the changing interface between computers and people. The integration of space science and computer science make space scientists gain some form of higher-level insight into massive data sets. So it is crucial to develop technology that supports presenting space data effectively. Scientific visualizationpsilas role in presenting...
With the development of Web application, network traffic is constantly increasing. In order to do the performance testing of Web applications, a precise simulation of network traffic is necessary. However, traditional traffic model based on Poisson process can not characterize the behavior of real network traffic. Measurements of network traffic show that the property of the self-similarity is ubiquitous...
We propose a simple and effective modeling method for creating animation opening flowers. Because the detailed geometry of flower petals is defined by a base shape deformation, we simulate the development of petal based on deformation and emulate its growth by change the deformation parameters. The structural arrangement of flower petals is established by the L-system that produces natural looking...
This paper proposed an improved video-based texture synthesis approach for simulating realistic natural phenomena. The algorithm measures similarity of every two frames to determine a preliminary playing sequence and then divide the preliminary playing sequence into several subsequences with different frame-to-frame delay so as to remove visual discontinuities. For removing the abrupt change from...
In this paper, we present an extensible, component-oriented, concurrent discrete-event driven wireless sensor network simulation platform: H-Sim. The components of the H-Sim system have high reusability and low coupling, it can solve the problems of having high coupling between modules and difficult to debug and use which exist in other simulation systems like NS-2. H-Sim can simulate the sensor nodes...
The phase of the frequency-shift keying (FSK) signal transmitted in frequency shift track circuits is continuous. The detection precision for FSK signals is restricted greatly due to the influence of interference signals. At present FSK signals are normally detected by using methods of wave filtering, spectrum analysis or signal transformation etc. However, it is more difficult to realize the demodulation...
