This paper proposes a discrete-time sliding mode controller coupled with an asynchronous multi-rate sensor fusion estimator which estimates the state of a rigid-link flexible-joint manipulator with visual sensing. In the multiple sensors robotic system, the fusion estimate method deals with the slow sampling rate and the latency of vision sensors by using motor encoders to cover the missing information between two visual samples. The discrete-time sliding mode uses the state estimation from fusion estimator which unique modifications simplify the design of the controller. The effectiveness of the proposed controller is illustrated by a computer simulation.

To investigate the significance of metastasis and invasion of MMP-9 and BRMS1 in breast cancer stem cells. The tissues from 65 breast cancer patients were divided into two groups, with and without lymph node metastasis, the CD44+CD24and Non-CD44+CD24- cells were separated from MCF-7 by immunomagnetic beads. ALDH1 and mRNA levels were measured by RT-PCR in different groups. The ability of metastasis and invasion in different group cells were detected by Transwell. MMP9-BRMS1 and ALDH1 were detected in different groups by immunnohistochemical staining. The level of ALDH1 mRNA in CD44+CD24- group was higher than other groups. More cells in CD44+CD24- group through the membranes than other two groups. Western blot showed that MMP9 and ALDH1 levels in CD44+CD24- group were higher than Non-CD44+CD24- cells but BRMS1 was lower (P<;0.05). MMP9 and ALDH1 expressions were higher in breast cancer tissues with lymph nodes metastasis than those without; while BRMS1 expression was lower in breast cancer tissues with lymph nodes metastasis. The expression of ALDH1 was positively correlated with that of MMP-9 and negatively with that of BRMS1 (P<;0.05). MMP-9 and BRMS1 play an important role in the metastasis and invasion of breast cancer stem cells.

This paper is focused on an infinite horizon H2/H∞ control problem for a broad class of discrete-time Markov jump systems with (x, u, v)-dependent noise. Above all, we develop a stochastic Popov-Belevich-Hautus (PBH) criterion for checking exact detectability. By which, an extended Lyapunov stability theorem is established in terms of a generalized Lyapunov equation. Further, a necessary and sufficient condition is presented for the existence of a state feedback H2/H∞ controller on the basis of four coupled matrix Riccati equations, which can be solved numerically by a backward iterative algorithm. Finally, a numerical example is supplied to illustrate the proposed theoretical results.

To address the uncertainty of production environment in knowledgeable manufacturing system, an interoperable knowledgeable dynamic scheduling system based on multi-agent is designed, in which a knowledge representation with a series of problem characteristics for various scheduling problems is adopted and problem-based function modules are constructed by using agent technology. An adaptive scheduling mechanism based on Q-learning (known as MA-Q policy) is proposed for guiding the equipment agent to select scheduling strategy in a dynamic environment. Simulation experiments show the scheduling system is of high intelligence and interoperability, and can constantly adapt to environmental changes by self-learning.

Focusing on the abrupt parameter variation of the aircraft dynamic characteristics brought by the wing damage, a multivariable adaptive reconfigurable control method has been studied. First the nonlinear 6DOF model of structural damaged aircraft is presented. The linearization process and the coupling between the longitudinal and lateral dynamics are studied, and the damaged aircraft dynamic model is denoted as a linear form with uncertain variations. And then the Multivariable Model Reference Adaptive Control (M-MRAC) method is introduced to compensate the abrupt variations in the state matrix, control matrix and the constant uncertainty. Finally NASA Generic Transport Model (GTM) is taken as an example and a typical case of left wing tip with 15% damage is considered. Three-channel attitude simulations are presented through comparing with PID control method. The results illustrate that the impact due to the parameter variations are significantly reduced, and the output tracks the desired trajectories rapidly and stably under uncertain damage.
针对机翼损伤引起的飞机动力特性参数突变问题，研究了一种多变量自适应可重构控制方法。首先建立了结构损伤飞机的非线性六自由度模型。研究了损伤飞机的线性化过程以及纵向和横向动力学之间的耦合，将损伤飞机的动力学模型表示为具有不确定变化的线性形式。然后引入多变量模型参考自适应控制(M-MRAC)方法来补偿状态矩阵、控制矩阵和恒定不确定性的突变。最后以NASA通用运输模型(general Transport Model, GTM)为例，考虑了典型的左翼尖15%损伤情况。通过与PID控制方法的比较，给出了三通道姿态仿真。结果表明，在不确定损伤情况下，由于参数变化造成的影响显著减小，输出能够快速稳定地跟踪期望轨迹。

In the design of 3D Network-on-chip, performance of the router is so important that it directly impacts the capability of 3D NoC. Considering the advantages and disadvantages of packet switching and circuit switching, this paper presents a mass message transmission aware buffer-less router for 3D NoC based on packet-circuit switching, which has the advantage of low buffer consumption and short transmission delay. That makes it suitable for mass message transmission on 3D NoC. We synthesize our mass message transmission aware buffer-less Packet-Circuit Switching Router for 3D NoC with XILINX 12.2. The device type is xc6vlx550t. The router can achieve a max frequency of 353.526 MHz, while the throughput of every channel is 16 Gbps.

Satellite antenna hold two degrees of freedom movement and positioning features to capture designated area information on the ground. The nonlinear characteristic of dynamic error impacts on pointing accuracy and satellite attitude. The forward and inverse dynamic model of satellite antenna is established firstly, Secondly, disturbance effects of Satellite Antenna are analyzed considering dynamic error of joint-flexible. Finally, real-time calculation of kinetic parameters of the antenna designed controller can directly compensate for dynamic errors caused by antenna joint disturbance. The asymptotic stability is established using Lyapunov stability theory. The result shows that the presence of dynamic error of flexible-joint can produce an unpredictable vibration response and velocity fluctuations even if the amplitude is small. With reasonable controller parameters, controller algorithm can completely compensate for the dynamic error and suppress its disturbance to satisfy the antenna pointing accuracy. The conclusion would have important academic value and engineering significance.

All seismic signal acquisition nodes must be synchronized so that they have the same sampling time for seismic signal acquisition in a distributed chained system with a large number of acquisition nodes. However, the propagation delay generated by the long-distance transmission link causes a synchronization acquisition error. In order to correct accurately the synchronization acquisition error, getting the accurate propagation delay size is a necessary condition. With regards to these, based on the detailed analysis of the propagation delay, a model and method for accurately measuring the propagation delay are proposed. Based on the model and method, the propagation delay can be measured accurately and then the delay calibration size can be transmitted to the corresponding acquisition node only through one transmission line. Then, an easy calibration method is proposed, and through it, the synchronization error can be completely eliminated. Simulation results show the effectiveness of the model and method proposed in the paper.
