The treatment of Non-Hodgkin's lymphoma (NHL) was revolutionized by the approval of rituximab in 1997. Rituximab is a CD20-directed monoclonal antibody (mAb). Despite the great success of rituximab in the treatment of B-cell NHL, the urgent need is to enhance the efficacy due to the markedly variable patient responses. Hence elucidating the molecular mechanisms of rituximab's anti-cancer effect is of great significance. In the past decade the atomic force microscopy (AFM) has proven to be a powerful tool for characterizing the morphological properties and measuring the physiological interaction forces of single cells and single molecules under native conditions. In this work, the AFM single-molecule force spectroscopy(SMFS) was applied to quantitatively measure the CD20-rituximab binding force on Burkitt's lymphoma patient bone marrow cells. The experimental results will facilitate further investigation of the molecular mechanisms of rituximab's anticancer effect. © 2010 IEEE.

To identify structures and parameters of complex stochastic nonlinear systems with accuracy and efficiency, preventing premature convergence during the evolution, an improved multi-objective hierarchical fair competition (HFC) parallel genetic programming (GP) algorithm was employed. The improved HFC GP algorithm was used to identify an object system based on nonlinear autoregressive moving average with exogenous inputs (NARMAX)model, good identification results were achieved with simultaneous identification of both structures and parameters of the object system. In comparison with single population GP and traditional multi-population GP, HFC-GP showed a more competitive performance in preventing premature convergence. It can be concluded that HFC-GP is good at solving complex stochastic nonlinear system identification problems and is superior to other existing identification methods.

with the demands for network security, some heterogeneous security equipments such as firewalls, intrusion detection systems, and anti-virus gateways are widely deployed in network, and produce massive security events which need to be merged and analyzed. Therefore, a distributed and multi-protocol supported network security monitoring system is proposed. The paper describes the architecture of the network security monitoring system. Focusing on the system acquisition layer, two methods are designed for monitoring data collection: syslog-based collection and real-time traffic-based collection. The ActiveMQ which based on the JMS specification..was adopted for data transmission...

Convex hull manipulation based control performance optimisation

WSEAS Transactions on Systems and control 2010年第8期5卷 691-700页

作者： Gróf, Patrícia Baranyi, Péter Korondi, Péter Computer and Automation Research Institute Cognitive Informatics Research Budapest Hungary Budapest University of Technology and Economics Dept. of Telecommunications and Media Informatics Budapest Hungary Budapest University of Technology and Economics Dept. of Mechatronics Optics and Engineering Informatics Budapest Hungary

This paper deals with the topic of qLPV state-space model based control design in which LMIs are used to optimize the multi-objective control performance. In this paper we investigate how the manipulation convex hull of the polytopic model influences the control performance which is derived by LMIs. We examine these influences through the control design of the two dimensional aeroelastic system's example. First we define various TP type polytopic model representations of a wing section whose vertices define different convex hulls. In the second step we investigate how these models lead to different control performances.

In this paper, we present an adaptive neuro-fuzzy controller design for a class of uncertain nonholonomic systems in the perturbed chained form with unknown virtual control coefficients and strong drift nonlinearities. The robust adaptive neuro-fuzzy control laws are developed using state scaling and backstepping. Semi-global uniform ultimate boundedness of all the signals in the closed-loop are guaranteed, and the system states are proven to converge to a small neighborhood of zero. The control performance of the closed-loop system is guaranteed by appropriately choosing the design parameters. By using fuzzy logic approximation, the proposed control is free of control singularity problem. An adaptive control based switching strategy is proposed to overcome the uncontrollability problem associated with x 0 (t 0 ) = 0.

The multiobjective collaborative optimization (MCO) has been widely adopted in concurrent engineering design as a good multiobjective optimization approach provided the problem of optimization results converging often to a local extremum has been taken care of. It has been demonstrated to yield useful solutions to a wide range of optimization problems under concurrent condition both technical and non-technical ones. A solution strategy for MCO that overcomes this drawback is proposed here on the grounds of genetic NSGA-II algorithm. It is an adaptive heuristic search technique that controls the distances between the individual and system's feasible region during genetic evolution. In the evolving NSGA-II based non-dominated sorting, the individual threshold of infeasibility degree is reduced gradually via genetic evolution and the individual's feasibility capacity is determined by its infeasibility degree and the threshold. It has been applied to a benchmark example of speed reducer design, and the obtained results demonstrate the proposed technique is comparably more efficient and may offer substantial advantages over the gradient-based optimization methods. © 2010 IFAC.

International Workshop on Variable Structure Systems, VSS

作者： Alejandra Ferreira Elisabetta Punta Department of Control Engineering Faculty Universidad Nacional Auténoma de México Mexico Mexico National Research Council of Italy Institute of Intelligent Systems for Automation ISSIA-CNR Genoa Italy

The paper considers the regulation problem of linear time invariant systems with unmatched perturbations. The proposed methodology exploits a high order sliding mode observer, which guarantees theoretically exact state and perturbation estimation. It is introduced a controller with a compensation strategy based on the identified perturbation values. When the system satisfies quite restrictive assumptions, the method ensures exact regulation of the unmatched states. In order to deal with the general case it is proposed a nested backward strategy to design the sliding surface, which allows to compensate the unmatched uncertainties and to stabilize some of the non-actuated state components, while all the remaining states are maintained bounded.

This paper addresses determination of constraint wrenches in singularities. The constraint wrenches imposed to the mobile platform by kinematic chains is proposed approach to rely on the theory of screws and influences of the criteria of singularity analysis to corresponding results for design of the parallel mechanisms. Further, using of the screw groups in order to determination of the singular zones of the multi-DOFs parallel mechanisms that make form of continuous areas is considered. Beside, automation of designing a parallel mechanism, which in purpose to achieve an increase their working volume, dexterity, and stiffness is developed. The method is used to propose optimal design of the parallel mechanisms based on the multi-criteria optimization obtaining the Pareto-optimal.
