In this paper, we investigate the L_2-L_{infinity} leader-following coordination problems with undirected switching topologies and external disturbance. The agent dynamics is expressed in the form of a second-order model and the control laws are neighbor-based feedback laws. We first establish a LMI sufficient condition to guarantee that all following agents can track the leader agent and the L_2-L_{infinity} disturbance attenuation of the system is not greater than a given constant. Furthermore, we get a explicit estimation expression of L_2-L_{infinity} disturbance attenuation by constructing a parameter-dependent common Lyapunov function. Finally, a numerical example is provided to illustrate the effectiveness of our results.

Based on the basic concepts and the main methods of bifurcation theory, we introduce the dynamic bifurcation Phenomenon in the power system voltage stability analysis and the relationship between them, making a more comprehensive summary and comment about dynamic bifurcation which used in the power system voltage stability analysis currently. In the text, we discuss the Hopf bifurcation (HB), period-doubling bifurcation, torus bifurcation and homoclinic (heteroclinic) bifurcation, among them, the Hopf bifurcation is discussed elaborated. Finally, We prospect the depth areas which the bifurcation theory in the voltage stability analysis need to be further explored.

The tribological properties of nano-Cu lubricating additives and electroless deposited Ni-W-P coating as well as their synergistic effect are researched using ring-block abrasion testing machine and Energy Dispersive Spectrometer. Research results show that the wear resistance of Ni-W-P alloy coating after heat treatment at 400??? has greatly increased since the Second Phase Ni3P particles were educed. In the friction process, nano-Cu in the lubricating additives deposited on the friction surface of Ni-W-P alloy coating so as to form a protective lubricating film, therefore the antiwear and friction reducing effects are achieved by the micro polishing effect, the load effect of micro ball bearing, the filling and repairing effects and formation of the chemical reaction film on the friction surface. Experiment results confirm that Ni-W-P alloy coating and nano-Cu lubricating additive have excellent synergistic effect, and form double protection for the metal substrate, e.g., the wear resistance of Ni-W-P alloy coating (with heat treatment and the oil with nano-Cu additives) has increased hundreds times than 45 steel as the metal substrate with the basic oil, zero wear is achieved, which break through the bottleneck of previous separate research of the above-mentioned the two.

Active power filter is an effective device to clear harmonics. Accurate detection of compensated components decides its compensation effect directly. This paper proposes an advanced instantaneous detection method for distorted three-phase system voltage by detecting fundamental positive sequence voltage and current respectively using d-q transformation. Thus fundamental positive-sequence active current and the compensated current components can be obtained exactly by phasor projection. The detection of voltage and current are simultaneous. Simulation results illustrate efficiency and accuracy of the improved method.

This paper presents a biologically-inspired approach for human tracking by using a single feature of opponent-motion and visual attention mechanism. Opponent-motion is a significant and salient feature during human motion of walking, running, etc. By the interaction with the heuristic prior knowledge of human model, the obtained opponent-motion is used to derive motion saliency from its statistical computation for rapid selection of salient motion blobs of humans by visual attention. The biological motion with available opponent-motion, therefore, can be effectively detected and tracked in real-time. The experimental results have also shown that detecting and tracking humans by opponent-motion can greatly eliminate the effect of illumination change. This work demonstrated that the feature of opponent-motion can be used for real-time human detection and tracking in natural and clustered environments.

In order to avoid routing overhead and reduce management fee for transmisson of routing information, we purposed two heuristic algorithms which are self-pruning algorithm and dominant pruning algorithm. This algorithm is more efficient than the aimless flooding in wireless networks, and redused unnecessary transmission of information and nodes switching by the movement between neighbourhoods. Result shows that the two kinds of flooding algorithms are obviously superior to the aimless flooding algorithm, particularly the performance of the dominant pruning could almost reach the limit.

In this paper, formal methods were introduced into the real-time embedded software testing field and a time-extended finite state machine, called t_EFSM, was proposed firstly. And then, based on the t_EFSM and combined with testing process of flight control software of an unmanned aerial vehicle (UAV), a method to generate the time-extended UIO sequence (t_UIO) was put forward. Finally, the method to generate test cases automatically according to t_UIO sequence was brought forward.

It is one of the focuses which are paid wide attention in the environmental protection field that the advanced and feasible desulphurization technologies are studied. Desulphurization technology by corona discharge is a novel and promising dry process for flue gas treatment. In flue gas desulphurization by corona discharge, the discharge characteristic of four electrode in direct current power and pulsed power were studied on the basis of desulphurization tests. It is resulted that under the same condition, desulphurization efficiency of pulsed power exceeds that of direct current power. By contrast ranking discharge characteristic of four electrodes, desulphurization efficiency of nozzle electrode is the first, sawtooth electrode is the second, spinous electrode is the third,the star electrode is the fourth. The reason is that discharge characteristic of electrodes lies on curvature radius. It is showed that desulphurization efficiency of ammonia coming in reactor from nozzle electrode is higher than that from pipe of fuel entrance.
