A new delay-independent stability analysis toolbox (DISAt) for use with the Matlab has been developed. The algorithm based on the new necessary and sufficient algebraic criteria for delay-independent stability of a class of neutral differential systems is implemented in this toolbox. This toolbox can be applied in testing the delay-independent stability of a class of neutral differential systems. Moreover, the maximal delay bound guaranteeing stability can be computed if the system is not delay-independent stable. The use of the toolbox is illustrated by several examples. Finally, a link to downloadable code is provided.

H-infinity control for networked control systems (NCS) with time-varying delays

控制理论与应用（英文版） 2005年第2期3卷 157-162页

This paper discusses H-infinity state feedback control for a networked control system with time-varying delays. Based on the flee-weighing matrix method, a dehy-dependent stability criterion satisfying a prescribed H-infinity norm bound is presented for an NCS with unknown, time-varying and bounded delays. And then, the criterion is transformed into sufficient conditions based on linear matrix inequalities for H-infinity control. The conditions thus obtained are also used to design an H-infinity state feedback controller. This design method is further extended to solve the design problem of robust H-infinity state feedback control. A numerical example demonstrates the validity of the method.

The tutorial presents state-of-the-art visualization techniques inspired by traditional technical and medical illustrations. Such techniques exploit the perception of the human visual system and provide effective visual abstractions to make the visualization clearly understandable. Visual emphasis and abstraction has been used for expressive presentation from prehistoric paintings to nowadays scientific and medical illustrations. Many of the expressive techniques used in art are adopted in computer graphics, and are denoted as illustrative or non-photorealistic rendering. Different stroke techniques, or brush properties express a particular level of abstraction. Feature emphasis or feature suppression is achieved by combining different abstraction levels in illustrative rendering. Challenges in visualization research are very large data visualization as well as multi-dimensional data visualization. To effectively convey the most important visual information there is a significant need for visual abstraction. For less relevant information the dedicated image space is reduced to enhance more prominent features. The discussed techniques in the context of scientific visualization are based on iso-surfaces and volume rendering. Apart from visual abstraction, i.e., illustrative representation, the visibility of prominent features can be achieved by illustrative visualization techniques such as cut-away views or ghosted views. The structures that occlude the most prominent information are suppressed in order to clearly see more interesting parts. A different smart way to provide information on the data is using exploded views or other types of deformation. Furthermore intuitive feature classification via 3D painting and manipulation with the classified data including label placement is presented. Discussed non-photorealistic and illustrative techniques from visualization and graphics are shown from the perspective as tools for illustrators from medicine, botany, archeology

Principal curve-based outlier detection model and its application in stock market

Jisuanji Yanjiu yu Fazhan/Computer Research and Development 2005年第8期42卷 1306-1311页

作者： Qi, Hongwei Zhang, Junping Wang, Jue Laboratory of Complex Systems and Intelligence Science Institute of Automation Chinese Academy of Sciences Beijing 100080 China Digital Technology Laboratory Institute of Computing Technology Chinese Academy of Sciences Beijing 100080 China

To solve the outlier detection problems where outliers highly intermix with normal data, a general variance-based outlier detection model (VODM) is presented, in which the information of data is decomposed into normal and abnormal components according to their variances. With minimal loss of normal information in the model, outliers are viewed as the top k samples holding maximal abnormal information in a dataset. The VODM is a theoretical framework, and then, the principal curve is introduced as an algorithm of it. Experiments carried out on abnormal returns detection in stock market show that the VODM is feasible.

Relaxation to equilibrium in few-particle adiabatic piston systems

Physical Review E 2005年第6期71卷 061103-061103页

O. Box 8730 Beijing 100080 China Beijing-Hong Kong-Singapore Joint Center of Nonlinear and Complex Systems Beijing Normal University Branch Beijing 100875 China

A Hamiltonian system with few particles and a heavy adiabatic piston is studied. With ensemble averages based on proper classification of slow and fast variables, a nonequilibrium state is defined and the relaxation from nonequilibrium to equilibrium is investigated. Coherent oscillation, dissipative oscillation damping, and anti-intuition energy transfer of the adiabatic piston are observed by numerical simulations. Noise-driven thermodynamic equations of slow variables are derived, based on the assumption of local equilibrium and the fluctuation-dissipation theorem, to understand and quantitatively reproduce all the above few-body nonequilibrium relaxation features.

Fast two-bit operations in inductively coupled flux qubits

A central problem for implementing efficient quantum computing is how to realize fast operations (both one- and two-bit ones). However, this is difficult to achieve for a collection of qubits, especially for those separated far away, because the interbit coupling is usually much weaker than the intrabit coupling. Here we present an experimentally feasible method to effectively couple two flux qubits via a common inductance and treat both single and coupled flux qubits with more realistic models, which include the loop inductance. The main advantage of our proposal is that a strong interbit coupling can be achieved using a small inductance, so that two-bit as fast as one-bit operations can be easily realized. We also show the flux dependence of the transitions between states for the coupled flux qubits.

Computed tomography plays an important role in industrial non-destructive testing, medical applications, astronomy and many other fields to look inside the scanned object and to analysis its inner structures. A non-destructive testing software have been developed to efficiently detect inner flaws of space industrial components. As the core of our software, reconstruction algorithms including preprocess of raw data, re-arrange algorithm and filtered back-projection algorithms have been described in detail in this article. With real raw data from CASC of China, experimental results verified the applied reconstruction algorithm in our software. Furthermore, forward algorithms simulating generation of fan-beam raw data are also presented in this article.
