The stochastic finite-time stability is studied in this paper for Markovian jumping neural networks with discrete and distributed delays. By defining a proper stochastic Lyapunov functional with mode-dependent Lyapunov matrices, a sufficient condition is derived such that the delayed Markovian jumping neural network under consideration is stochastically finite-time stable with respect to prescribed scalars. The stability criterion is delay- and mode-dependent, and can be readily checked by resorting to available algorithms. Two numerical examples are finally provided to show the application of the developed theory.

This paper proposes a novel method to synthesize robust PID (proportional integral derivative) controller via Kharitonov's theorem and genetic algorithm for wastewater treatment. The H∞ specifications and Kharitonov's theorem result to solve a non-convex optimal problem subjected to several inequality constraints. The genetic algorithm is used to search the robust PID controller parameters wihout solving the steady-state Riccati equations. The novel robust PID is applicated for simplified Activated Sludge Model No.1 (ASM1) to keep the concentration of the biomass proportional to the influent flow rate with model uncertainties. Simulation shows that the algorithm is simple and effective for uncertain wastewater treatment.

Stability plays an important role in the practice. In this paper, exponential stability of nonlinear dynamic systems with delay is discussed. Some conditions which guarantee exponential stability of the nonlinear dynamic systems are given by by Hurwitz matrix theory. Finally, an example is given to illustrate the theoretical result.

The accuracy of RSS fingerprint based indoor location algorithms in Wi-Fi environment depends on the density of sample points and the quality of AP radios. It has been observed that in a given area the accuracy can be improved by just using the RSS data from a sub set of whole APs. So the location algorithm based on AP reduction is studied in this paper, and 3 kinds of sample points clustering methods, which are spatial clustering, K-means clustering and Affinity Propagation Clustering, are tested to generate the appropriate area for each AP sub set. The results of experiments shows that the AP reduction algorithm can obviously reduce location error. At the same time, the algorithm's complexity gets reduced.

The problem of asymptotic stability analysis is investigated about a class of delayed neural networks with homogeneous right-hands sides. Under the assumption that the trivial solution of delay free system is asymptotically stable and the activation functions are homogeneous, it is proved that the zero solution of delayed neural network is asymptotically stable for arbitrary nonnegative delay. By constructing a Lyapunov function and employing the nature of homogenous function, a new delay-independent asymptotically stability condition of the neural network with delay is obtained. At the end of the article, an appropriate numerical example which can demonstrate the effectiveness of the main result will be given.

The upgrade of control system for a remotely operated vehicle (ROV) is introduced. By applying only one computer for vehicle control, both reliability and the maintenance have been achieved. Moreover, future functional expansion has been made possible by adopting modular hardware. The control software, which is developed under the graphical user interface development environment of MATALB, provides both a user-friendly interface and real-time control capability by applying event-driven callbacks. Primary tests verify the effectiveness of the control system developed.

Based on a modified nonlinear dynamic ECG model, this paper presents an extended Kalman Rauch-Tung-Strebel (RTS) smoother to estimate the maternal ECG (MECG). The MECG is the predominant interference in the estimation of fetal heart rate (FHR) from abdominal ECG signals, by which, the obstetricians can determine whether the fetus is in a state of distress. For the presented smoother, an automatic parameter selection method is offered to estimate ECG signal model parameters from abdominal ECG signals themselves. Performance analysis based on both synthetic and realistic abdominal ECG signals demonstrates that the extended Kalman RTS smoother is more accurate than conventional extended Kalman filter and outperforms the other methods, such as wavelet denoising (WD) or blind source separation (BSS), due to its low computational complexity and simpler lead configuration. The presented extended Kalman RTS smoother could be applied to long-term at-home monitoring of fetal well-being.

Direct yaw moment becomes an external input to in-wheel-motors (IWMs) electric vehicles (IEVs) besides steering angle usually as the only input to traditional vehicles. To improve the handling and stability of IEVs, a good knowledge of the effect brought by direct yaw moment is necessary. First, in this paper, reference model based on 2 DOF bicycle model is built for the control strategy. Second, vehicle model is built, and DYC based on sliding mode algorithm is proposed by using model based control method to evaluate the impact on the vehicle behavior. Then, simulations on different maneuvers are carried out and the values of vehicle states are compared especially in wheel steering angles and axle sideslip angles. Finally, conclusions are given.

A new method of circular traffic light detection and recognition was proposed for the visually impaired person to help them cross the road. Similar circular and rectangular shapes detection combined with the intensity analysis was used to locate the candidate traffic lights. And traffic light color recognition was realized using color distributions of the light area in HSI color space and shape features of the lamp. Voice prompt was given after analyzing the recognition results of video sequences. Experimental results showed that the traffic light detection and recognition method has high recognition rate of 98%, and the frame processing speed was 0.09s, which met the real-time requirements.
