This paper investigates the stability and control of some input-delayed switched systems while delays contain constant delays and time-varying delays. Based on the reduction method, Lyapunov stability theory and LMI approach, a state feedback controller, a switching strategy and the stabilization conditions of the system are proposed. Finally, we use a simple model to proof that the controller using the reduction method can stabilize a larger class of systems than those existing memoryless controllers.

This paper starts with the integrated dynamic capability view (IDCV), the theoretical basis of alliance capability. Then it analyzes basic units of the IDCV - routine and organization process and their relations with alliance capability in details. And then it researches on the relationship between the routinepsilas inherent characteristics, evolutionary process and the alliance capabilitypsilas components, formation process. Finally it establishes the theoretical model of the alliance capability and proposes corresponding hypotheses. To prove the reasonability of such theoretical model, the paper puts forward a structural equation model (SEM), which is tested by a large sample including 147 Chinese high-technology firms. The empirical results are complied with the paperpsilas research design and hypotheses.

Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Most of the attention, however, has been given to the routing protocols. The paper presents a new clustering scheme named HCMC based on improved Monte-Carlo localization algorithm MCBR. We also exploit multi-hop scheme between clusters to increase the energy efficiency of the protocol. The results show that our approach distributes the energy dissipation more evenly than other clustering schemes, reduces overall energy consumption and improves network lifetime.

CPL (Call Process Language) is a scripting language for the description and control of communication service, and it expresses its content by using functional component in XML language. This paper presents a component reuse mechanism, and defines a matrix technique to inspect the conflict of component composition. By comparing the difference of CPL and Java grammar, this paper brings forward a translation mechanism, via which we can translate CPL to equal functional Java code in the framework of XML language. This mechanism adopts the idea of EJB container, and constructs the whole services after the form of class object, and describes the CPL componenst as JavaBeans. By this way, the Java code translated has character of easily readable, highly reusable and extendable. This mechanism is applied in our service creation system, and achieves good results.

To update the variable system timely, an updating strategy, which is based on the distributed object technology, is presented by this paper. By this strategy, a COM component-oriented updating system framework based on distributed object technology is implemented. On the basis of observer design pattern, the framework takes advantage of the remote processing technology to implement the dynamic updating of software based on component. Both the theory and practice proof that it is an efficient solution to eliminate the disadvantage of traditional way of software updating.

Power quality (PQ) has become a major concern to both electric utilities and customers in recent years and more functions for power quality monitoring system (PQMS) is required. This paper presents a distributed power quality monitoring system that is based on ARM9 and SOPC. ARM9 with the embedded operating system Linux deals with data display and storage. SOPC designed as terminals do data sampling and processing. With the use of Qt/Embedded, the system has a friendly man-machine interface. This system can monitor a number of power-quality indices on every load connected to the same point of common coupling and transmit the measured values to a master device. The master device processes the values to locate the sources of unbalance and harmonic distortion and to quantify the effects of such disturbances on power quality.

In order to overcome the overfitting problem caused by noises and outliers in support vector regression (SVR) ,a weighted coefficient model based on support vector data description (SVDD) is presented in this paper. The weighted coefficient value to each input sample is confirmed according to its distance to the center of the smallest enclosing hypersphere in the feature space. The proposed model is applied to weighted support vector regression (WSVR) for 1-dimensional data set simulation. Simulation results indicate that the proposed method actually reduces the error of regression and yields higher accuracy than support vector regression (SVR) does.
