作者： Yalin Yao 1 Junping Liu 2.1 college of electrical and {2. engineering Hunan university of Technology Zhuzhou 412.07 china 2.college of electrical and {2. engineering Hunan university of Technology Zhuzhou 412.07 china

the cultivation of students’ innovation spirit and ability has become a hot topic of general interest in the current Chinese education. Experiment teaching is an important way to cultivate students’ innovation ability. Electrotechnics is an important technological basic course for engineering non-electricity specialties of colleges and universities, which includes the two parts of theory teaching and experiment teaching, and electrotechnics experiment is an important link of the course. To fully implement innovation quality education, experiment teaching has received increasing attention. This paper starts from strengthening experiment teaching reform and improving teachers’ teaching innovation ability and innovates experiment teaching from educational concepts, teaching contents and methods and examination mechanism to explore ways to cultivate college students’ innovation quality in electrotechnics experiment teaching.

In this paper, a novel method for constructing quasi-cyclic LDPC codes with low complexity is proposed. By choosing each circulant permutation matrix sequentially, the proposed method ensures that the current circulant permutation matrix forms no cycles of length smaller than g with the existent circulant permutation matrices. The construction complexity of the proposed algorithm is much lower than that of the random construction. Simulation results show that the proposed QC-LDPC codes can outperform both the random regular LDPC codes with short to moderate block lengths, and the proposed construction method LDPC codes based on the finite geometries in terms of bit-error-rate (BER).

In this paper we consider a queueing network consisting of two parallel servers and threearrival streams generated by independent Poisson sources. Each server has its own queue and receivescustomers from its own arrival stream. A third arrival stream consists of customers which place resourcedemands on both servers, which are handled separately by each server once the request is made. Eachservice time is independent and exponentially distributed. Each customer in the system pays a holdingcost per unit time. The objective is to dynamically determine the optimal scheduling policy to the thirdstream of conupled customers. based on the state of the system, so as to minimize the average cost. Thismodel is new, and has Policy implications for computer or communication networks. A fuzzy approachis presented to solve this problem. Simulation shows that the approach is efficient and promising.

基于前置维纳滤波的多用户MIMO系统下行链路线性预编码方法

This paper considers the containment control of linear multiagent system with weakly connected information topology. By defining the node-induced strongly connected subgraph as strong component, the agents contained in strong components with zero in-degree are called leaders and the others are called followers. Then, a sufficient and necessary condition is proposed for all agents to achieve containment by employing an observer-based protocol, where all followers finally converge to the convex hull formed by leaders and each strong component of leaders asymptotically achieve consensus. Since the number of leader agents in each strong component are always larger than one, the proposed scheme is more robust for the malfunction of leaders. Further, two LMIs are given to design the observer-based protocol. Numerical examples are included to illustrate the validity of the proposed results.

关键词： Multi-agent system Observer-based Containment Control Consensus.
