In this paper, a key performance indicator (KPI) related multiplicative fault diagnosis scheme is proposed for static industrial processes. This scheme is developed for an alternative algorithm to the standard partial least squares (PLS) based process monitoring, where no design parameter like "latent variable number" is involved. Based on both normal and faulty data sets, the multiplicative fault information is firstly estimated. With this knowledge, the most critical low-level control loop/component is further identified. Different from the existing data-driven additive fault diagnosis approaches, this scheme aims to handle the second order statistics, which is of fatal importance for KPI-related fault diagnosis. Finally, an academic example is investigated to illustrate the functionality of this scheme.

Global output feedback stabilization for a class of nonlinear planar systems with output-dependent growth rates

IFAC Proceedings Volumes 2013年第20期46卷 683-688页

In this paper, we consider the global output feedback stabilization problem for a class of nonlinear planar systems under a more general growth condition. The nonlinearities in such a system are bounded by both lower-order and higher-order terms with an output-dependent growth rate. This problem is solved by integrating the feedback domination technique and a novel dual observer approach, where two individual observers are constructed in parallel with one estimating the linear part of the unmeasurable state and the other estimating the higher-order part. Moreover, the presented observers and the output feedback controller all have nonlinear gains. Simulations illustrate the effectiveness of the proposed stabilization scheme.

In this paper, we propose a unified TDMA-based scheduling protocol for Vehicle-to-Infrastructure (V2I) communications. In the proposed TDMA-based scheduling protocol, the roadside infrastructure collects the information from the vehicles within its communication coverage through a control channel at the beginning of each transmission frame and then decides how to allocate the time slots to the vehicles for their data transmission requests based on a new designed weight-factor-based scheduler. The provided weight factor jointly takes into consideration the channel quality of communication links, the speed based fairness among vehicles, and different access categories. Simulation results verify the efficiency of the proposed scheduling protocol in terms of the network throughput performance, the fairness among the vehicles, and different accessing priorities of different access categories.

Discovering temporal patterns and changes in tobacco use has important practical implications in tobacco control. This paper presents one of the first comprehensive international studies of seasonal smoking patterns based on online searches performed. Using periodogram and cross-correlation, we find that smoking-related search behavior shows strong seasonality effect across countries. In addition, there are significant pairwise associations between such seasonality in different countries.

Till now, most lawn is still irrigated manually or timely. That means lack of proper irrigation strategy and information management ability. However, irrational irrigation method will not only lead to unhealthy growth of lawn, but also waste of water. A new idea for lawn intelligent remote irrigation was put forward. The smart sprinkler strategy was created by researching the characters of lawn, such as water demand, heat resistance and diseases law. And the embeded control system can apply the strategy to irrigate intelligently. Tying the urban lawn features, the system was designed to be driven by solar, which makes it an energy self-sufficiency system. What's more, the sprinkler system gains the CAN bus-based network management function, which simplify the user's contol and management. Finally, the experimental results show that the system has the advantages of good effect, low cost, high reliability, easy maintenance, etc. And it will meet the demand of energy saving and environmental protection.

In this paper, we for the first time consider the space-time network coding (STNC) to propose a novel cooperative data dissemination strategy in the time-division multiple access (TDMA) manner for the vehicle network, to overcome the short-comings of the traditional network coding (NC) techniques with carrier sense multiple access/collision avoidance (CSMA/CA) protocol, i.e., high signal detection complexity and channel collision problem. An optimal relay selection strategy in the procedure of cooperative data dissemination is proposed to maximize the average system capacity for the data dissemination. In a addition, a suboptimal relay selection strategy is put forward to reduce the computation complexity and thus makes the developed data dissemination strategy more practical. Compared with the non-cooperative data dissemination, the proposed cooperative data dissemination via STNC has better performance in terms of the average system capacity, the average user equipment (UE) capacity, and the average data dissemination delay.

The design and control methods of robotic system for vascular interventional surgery is studied in this paper. By considering the characteristics of vascular interventional surgery and operation habits of surgeon, a master-slave remote control catheter system is presented. The system consists of three parts: the operation handle, the catheter manipulator and the host computer. The operation handle is designed to simulate the surgeon's surgical procedure, and the catheter manipulator tracks the handle's movements in both translation and rotation directions. Real time communication between the operation handle and the catheter manipulator has been built based on the host computer. Effectiveness and speed tracking performance between the catheter manipulator and the handle was validated by simulation experiments on a human vascular model.

For the existing problem of conventional adaptive control and multi-model adaptive switching control theory and method, a robust adaptive control via multi-model switching method for the SISO(Single Input Single Output) discrete systems. Many multi-model subsets have override the model set of the system parameters, which consist of the fixed models and adaptive models together. The best matching controller has been selected as the system controller from the design of the switching index function, which can greatly improve the system transient performance. Simulation results show that the proposed algorithm has greatly enhanced the robustness of the system and improved the transient characteristics of dynamic systems.

In a world where possessing raw materials or manufacturing commodities are not sufficient for long-term economic success, innovativeness and a knowledge-based economy form the basis for prosperity. In this report, we discuss the link between a nation's higher education system and its ability to bring about and foster innovativeness and economic growth. In particular, we will concentrate on the roles that universities play in the national innovation system. Some of the questions we address include: How strong a link is there between the education system and nation's innovativeness? How important is industry-academia collaboration? From the perspective of a knowledge-based economy, what would an ideal university be like? To answer these questions, we summarize key findings from the literature. The aim of this report is to present the key factors and decisions that should be considered in future higher education strategies.
