This paper gives a complex dynamical network model. In this network, the agent interacts with its neighbors with time-varying delays. Using the Lyapunov method and the matrix inequality, we discuss the synchronization of the proposed network based on the synchronous target with and without time- varying delays, respectively. Furthermore, we verify our theoretical results by some simulations.

With the development of agricultural production technology,characteristics that appear in the farmland information such as diversity,polytropy and dispersity. In order to solve the problems of obtaining quickly and long-distance transmission the farmland information,the paper proposes a farmland data acquisition system based on the GPRS technology. The system exerts GPRS network of the china mobile communications and combines integrated circuits,sensors and GPRS communication modules on data transmission,and establishes the whole crop monitoring system. Through the Internet,GPRS and field monitoring communications,the data center can finish a complete record,the curve showing and query of field data,meanwhile it can detect equipment remotely. These instructions give you the basic guidelines for preparing papers for WCICA/IEEE conference proceedings.

Student engagement is a pervasive and persistent goal for educators. In previous work we have reported that activities like public real-time commenting on videos can enhance student participation and engagement. However, these events occur over a limited period of time. Thus a more challenging question is how to increase and sustain student engagement. In this paper we describe the iterative development of Class Commons, a public commenting system with which students can post questions/comments that are shared through a public display in the classroom. The system was used in a senior undergraduate class in the spring semester of 2009. Our findings suggest that students were interested in this system. Students with different self-construal (independent vs. interdependent) appropriate this system for slightly different purposes. In the long run, we speculate that by having the teacher involved more in using this system (responding more quickly, helping structuring the discussions), it has potential for promoting sustained student engagement.

This paper proposes flexible security protocol for synchronous and asynchronous collaborative editing environment. The flexible security protocol comprises of preventive and corrective measures. The preventive measures ensure user authentication, access control and data confidentiality. The corrective measure includes fault tolerant measures to ensure data integrity.
