This paper presents a reasoning method based on the combination of Textual CBR and RBR to deal with the case described by the natural language with the intention of resolving the information retrieval in the flight-test procedure. Then experiments are made by using the reasoning system based on the method. The results show that not only could the method retrieve the cases from the system correctly, but also the Textual CBR procedure could complement the RBR procedure when the latter one cannot retrieve the case correctly. Thus the method could efficiently increase availab.lity of the reasoning system. © Springer-Verlag Berlin Heidelberg 2014.

In this paper, a novel visual tracking algorithm that uses the target salient confidence (TSC) is proposed. Two contributions are summarized as follows. First, we put forward a novel target salient confidence (TSC) model which combines the static saliency map (SSM) based on the selective visual attention model, motion attention map (MAP) and the target prior confidence (TPC). Second, we propose to use the target salient confidence for particle filter. It manipulates the distribution expressed by the particle cloud towards a better match with the target salient confidence model. In this way particle sampling can be locked on those regions with higher target salient confidence. Experiments in some video sequences show that the target salient confidence is useful for visual tracking and our algorithm is effective.

An overview of the active disturbance rejection control (ADRC) is presented in this talk. Ever since ADRC was proposed by Jingqing Han in 1990s[1]1, it has become quite an attractive methodology to applied researchers, even though rigorous theoretical justification was lagging behind for quite some time. The fact that ADRC possesses certain uniqueness in concepts, simplicity in engineering implementation, and superior actual performance allowed it to be readily translated into a valuable asset in engineering practice: namely, the ability in dealing with a vast range of uncertainties, improved transient response, easy implementation and energy savings, to name but a few. The range of applications seems broad, covering almost all domains of control engineering, such as motion control, speed control of induction motor and permanent-magnet synchronous motor, control for noncircular turning process, low-velocity compensation of brushless DC servo, robotic system, underactuated mechanical systems, micro-electro-mechanical systems gyroscope, control for superconducting RF cavities, flight control, attitude tracking of rigid spacecraft, web tension regulation, DC-DC power converter, chemical processes, ALSTOM gasifier benchmark problem, the boilerturbine-generator control systems, stabilization of axial flow compressors, the fractional-order system, etc. [10]-[31]. In the U.S.A., the ADRC solution was recently deployed at a Parker Hannifin Extrusion Plant in North America, resulting in over 50% energy saving per line across ten production lines, together with significant improvements in product quality [32]. And Texas Instrument has adopted the ADRC technology in developing and distributing a new line of motion control chips worldwide [33].The National Superconducting Cyclotron lab.in the U.S. has implemented ADRC in several high energy particle accelerators after significant improvements have been obtained in amplitude and phase regulation of electromagnetic fields.

Subspace clustering is a powerful technology for clustering data according to the underlying subspaces. Representation based methods are the most popular subspace clustering approach in recent years. In this paper, we analyze the grouping effect of representation based methods in depth. In particular, we introduce the enforced grouping effect conditions, which greatly facilitate the analysis of grouping effect. We further find that grouping effect is important for subspace clustering, which should be explicitly enforced in the data self-representation model, rather than implicitly implied by the model as in some prior work. Based on our analysis, we propose the SMooth Representation (SMR) model. We also propose a new affinity measure based on the grouping effect, which proves to be much more effective than the commonly used one. As a result, our SMR significantly outperforms the state-of-the-art ones on benchmark datasets.

Communication-Based Train control (CBTC) system is an automated train control system using bidirectional train-ground communications to ensure the safe operation of rail vehicles. Due to unreliable wireless communications and frequent handoff, existing CBTC systems can severely affect train control performance. In this paper, we use recent advances in Coordinated Multi-Point transmission and reception (CoMP) to enhance the train control performance of CBTC systems. In addition, unlike the exiting works on CoMP, linear quadratic cost for the train control performance in CBTC systems is considered as the performance measure. Moreover, we propose an optimal guidance trajectory calculation scheme in the train control procedure that takes full consideration of the tracking error caused by handoff latency. Simulation results show that the train control performance can be improved substantially in our proposed CBTC system with CoMP.

According to the problem of not making full use of the road resources and not adapting the changeable traffic situation based on the traffic lights with the fixed cycle and the fixed phase sequence, this paper defines a kind of Fuzzy Hybrid Petri nets (FHPN) to simulate the real-time control for the traffic signal. The traffic signal control based on the Fuzzy Hybrid Petri nets not only can compute the best green light duration of each phase in time but also can determine the reasonable and alterable phase sequence. The simulation analysis shows that the real-time traffic signal control based on the Fuzzy Hybrid Petri nets can reduce furthest the count of the vehicle second stops, so the average delay time of the vehicles and the passengers can be reduced. © 2014 Binary Information Press.

Previous epidemiological researches have studied HFMD transmission pattern, but the study on the patients mobility pattern while seeking treatment is absent. In this paper, we present a statistical analysis of the spatialtemporal pattern of the Beijing HFMD patients mobility based on a complete works dataset containing over 40,000 cases in 2010. The main findings are as follows: (1) the patents incline to take their sick children to hospitals on weekdays, especially on Monday;(2) the patients living far from city center are more likely to get to hospitals in the afternoon, while the patients in the downtown in the morning;(3) patients (or their parents) either select the nearby hospitals, or the Class-A hospitals in the downtown. Furthermore, we employ a gravity model to describe the spatial mobility pattern of patients. The experiment results show a good fit. © 2013 Springer-Verlag.

This paper presents an improved method to teleoperate impedance of a robot based on surface electromyography (EMG) and test it experimentally. Based on a linear mapping between EMG amplitude and stiffness, an incremental stiffness extraction method is developed, which uses instantaneous amplitude identified from EMG in a high frequency band, compensating for non-linear residual error in the linear mapping and preventing muscle fatigue from affecting the control. Experiments on one joint of the Baxter robot are carried out to test the approach in a disturbance attenuation task, and to compare it with automatic human-like impedance adaptation. The experimental results demonstrate that the new human operated impedance method is successful at attenuating disturbance, and results similarly to as automatic disturbance attenuation, thus demonstrating its efficiency. © 2014 Springer International Publishing.
