Currently, open-loop deep brain stimulation is an effective treatment for Parkinson's disease, the stimulus waveforms are static high-frequency pulse sequences. In this paper the input-output feedback linearization method is introduced in the closed-loop control of Parkinsonian state based on a computational model. Closed-loop control effects are compared with the classical open-loop control. Simulation results prove that feedback linearization method performs better than the open-loop controller for the restoration of thalamic relay function under Parkinsonian state.

This paper aims at determining several designing considerations for star tracker which uses on aircraft during daytime at altitudes around 10 km. From analysis of operational environment, the sky background radiation caused by the sun is the main factor which affects the performance of star tracker. In order to research insight, star magnitude model is established to calculate stellar radiation and MODTRAN software is used to obtain the sky background radiation. The contrast of detection, the ratio of stellar radiation and sky background radiation, is defined as the criterion to determine these considerations. Finally, H-band waveband, from 1.5μm to 1.7μm, is chose as the optimal detection waveband due to better comprehensive performance in detection. InGaAs detector is selected for the airborne star tracker after trade-off studies included a comparison in terms of detector format, cost and cooling requirements. Simultaneous measurements with three field of view are determined as the preferred design prototype because of higher detectable limiting magnitude and star detection probability.

Multi-level threshold segmentation techniques are one of the most important parts in image processing. They are simple, robust, and accurate. However, some of them have long computation time and it grows exponentially with the number of thresholds increase. This paper proposed an improved differential evolution with novel mutation strategy and adaptive parameter controlling method (MApcDE) so as to avoid time-consuming and overcome the relation between computation time and dimensions. OTSU method, which maximizes the variance between foreground and background in an image, is a popular threshold image segmentation technique, and is used in this paper to test the performance of the proposed method. Experimental results show that our proposed MApcDE algorithm can get more effective and preferable results when compared with some other population-based threshold methods. The computation time is shorten at the same time.

The IOT-based building energy consumption management system, as an important technology management means for energy efficiency, is prevalent and applied widely. Nevertheless, the requirement of occupant comfort environment is rarely considered in most previous studies. In this paper, based on intelligent sensing technology, we put forward a novel system framework for building energy consumption management systems, which focuses on providing the comfort environment for occupants in energy saving. Firstly, the energy efficiency sensing and control unit is developed, which consists of several sensors for environment comfort evaluation and data fusion. In addition, the feedback control is realized in this unit through multi-sensor integration and GPIO ports. The concept of collaborating with people, machine and substance is reflected in the working process of this unit. Secondly, the relation between environment factors and energy consumption control is clearly described with the event-based ECA-rules. The real-time response to environment sensing and energy consumption data streams is achieved by utilizing complex event processing. Finally, the application scenarios show the benefits of the proposed system architecture.

This paper is concerned with the problem of average consensus in directed networks of agents with both switching topology and time-delay. A proportional and derivative like (PD-like) consensus algorithm is developed to address such a problem, which improves the convergence rate. Also, a constant delay and a time-varying delay are taken into account respectively. The stability analysis is performed based on a proposed Lyapunov-Krasovskii function. Then, some new consensus conditions are given to guarantee the average consensus under arbitrary switching topologies. Finally, a numerical example is given to show the effectiveness of the developed results.

A three-dimension chaos shape synchronized system is proposed and used in the secure communication. The proposed system consists of a Chaotic Secure Transmitter (CST) and a Chaotic Secure Receiver (CSR). Because of the driving signals are the shape features of drive systems, the attackers are highly unlikely to obtain reconstructing the chaotic dynamics of the drive systems. The simulation results show that encryption effect is well, and the recovered signal is less different from the original signal. The system has the high safety performance and wide application.

In this paper, we investigate an opinion formation model with stubborn agents, where each agent updates her opinion according to opinions of her neighbors as well as her own initial opinion with some degree of stubbornness. Generally, the presence of stubborn agents will preclude consensus and result in a steady distribution with different opinions. Here, we investigate how effectively the initial opinions can influence the opinion formation. And, we find that any steady distribution can be reached if the stubbornness of each agent is nonzero; otherwise, only the steady distribution located in a special space can be reached. Furthermore, we develop a simple criterion to judge whether or not a steady distribution is reachable. For a reachable steady distribution, a method for the choice of the corresponding initial opinions is presented; while for an unreachable distribution, an algorithm is designed to find a reachable distribution which is closest to the desired one.

Volt-ampere characteristic(I-V) curve is one of the most important characteristics of solar arrays, and is an indispensable reference for field performance testing and designing of concentrating photovoltaic power generation system. However, customers can only get the curve under standard condition from manufacturers, but the actual operating environment varies widely. There are two difficulties to get a continuous and accurate I-V curve in any conditions, one is a variable resistor ranges from 0 to infinity; the other is wide range of measured objects which makes it inaccurate when measuring small signals. This paper uses capacitor charging method to simulate a variable resistor, and presents a method that combining a digital potentiometer and an instrumentation amplifier to get a flexible, programmable gain amplification circuit to solve the aforementioned difficulties. Besides, a touch screen with friendly user interface makes the tester easier to use, and the capability of data storage in SD card facilitates further analysis of the data.
