The 1st Chinese Conference on Trusted Computing and information Security

作者： LI Ji-guo. ZHANG Yi-chen. ZHU Yue-long college of Computer and information Engineering, Hohai university, Nanjing 210098, Jiangsu, china

＜正＞ A proxy signature scheme with message recovery using self-certified public key is proposed. which withstands public key substitution attacks, active attacks, and forgery attacks. The proposed scheme accomplishes the tasks of public key verification, proxy signature verification, and message recovery in a logically single step. In addition, the proposed scheme satisfies all properties of strong proxy signature and does not use secure channel in the communication between the original signer and the proxy signature signer.

第24届中国控制与决策会议

作者： Jian Li the college of information Science and Engineering, Northeastern university and Guang-Hong Yang the college of information Science and Engineering, Northeastern university, Key Laboratory of Integrated Automation of Process Industry(Ministry of Education), Northeastern university

The problem of robust fault detection filters for switched systems systems with sensor fault. Different from the average dwell time （ADT） switching, the switched systems are switched with mode-dependent average dwell time switching law which means that each subsystem has its own ADT, its own decay rate of the Lyapunov-like function and its own increase coefficient of Lyapunov-like function at switching instants. An analysis condition to capture the weighted 2 performance for switched systems with mode-dependent average dwell time （MDADT） is presented. With the aid of multiple Lyapunov-like functions and Projection Lemma, a procedure of robust fault detection filter synthesis is given in terms of linear matrix inequalities （LMIs）. Finally, an example is given to illustrated the effectiveness of the proposed method.

A Class of Iteration Method for the Best Approximation Problems

引用

Advances in Manufacturing 1998年第1期 18-24页

作者： Wang Deren Zhao Fengguang (college of sciences)

We propose a class of iteration methods searching the best approximately generalized polynomial, which has parallel computational function and converges to the exact solution quadratically. We first transform it into a special system of nonlinear equations with constraint, then by using to certain iteration method, we combine the two basic processes of the Remes method into a whole such that the iterative process of the system of nonlinear equations and the computation of the solution to the system of linear equations proceed alternately. A lot of numerical examples show that this method not only has good convergence property but also always converges to the exact solution of the problem accurately and rapidly for almost all initial approximations .

Introduction Progressive myocardial remodeling and deterioating cardiac function is a central feature of heart failure. The cellular and molecular changes contributing to the contractile dysfunction of the remodeled myocardium are poorly understood. Intracellular Ca2+ homeostasis is critical for effcient myocardial function. Sarcoplasmic reticulum Ca2+-ATPase (SERCA) and SERCA regulatory protein phospholamban(PLB) are the major proteins responsible for intracellular Ca + homeostasis throughout excitation-contraction cycling in cardiomyocytes. Changes of the abundance or function of these molecules

Jacquard image inpainting is an interesting new research topic in pattern preprocessing for jacquard *** field model has been well acknowledged as an important method for image *** paper discussed the problem of jacquard image inpainting by approaching the phase field paradigm from a numerical approximation *** basic idea is to represent the damaged pattern of interest in implicit form,and fill-in the damaged parts with a system of geometric partial differential equations derived from phase-field *** novelty of our approach lies primarily in exploiting explicitly the constraint enforced by the numerical solving of the sequential evolving of phase-field *** experiments are carried out in order to validate and compare the algorithm both quantitatively and *** show the advantages of our algorithm and its readily application to jacquard texture.
