Data Synchronization Solution Based on Virtual Log Compression
Computer Engineering, 2010Co-Authors: Zhang Chun-lingAbstract:In the field of Data Synchronization based on virtual log,Huge log records affect the efficiency of Data Synchronization,when the master side has frequent changes in same record.For the problem,Data Synchronization is proposed based on the virtual log compression.Virtual log compression is calculate and merge log records,and only those records related with Data Synchronization are left and therefore reducing network traffic and improve the efficiency of Data Synchronization.Results show that virtual log compression is particularly suitable for heterogeneous Database and asynchronous Data Synchronization in WAN.

Sampled-Data Synchronization Control of Dynamical Networks With Stochastic Sampling
IEEE Transactions on Automatic Control, 2012Co-Authors: Bo Shen, Zidong Wang, Xiaohui LiuAbstract:This technical note is concerned with the sampled-Data Synchronization control problem for a class of dynamical networks. The sampling period considered here is assumed to be time-varying that switches between two different values in a random way with given probability. The addressed Synchronization control problem is first formulated as an exponentially mean-square stabilization problem for a new class of dynamical networks that involve both the multiple probabilistic interval delays (MPIDs) and the sector-bounded nonlinearities (SBNs). Then, a novel Lyapunov functional is constructed to obtain sufficient conditions under which the dynamical network is exponentially mean-square stable. Both Gronwall's inequality and Jenson integral inequality are utilized to substantially simplify the derivation of the main results. Subsequently, a set of sampled-Data Synchronization controllers is designed in terms of the solution to certain matrix inequalities that can be solved effectively by using available software. Finally, a numerical simulation example is employed to show the effectiveness of the proposed sampled-Data Synchronization control scheme.

Data Synchronization Strategy Based on Conflict Resolution for Research Online Mobile
Computer Engineering, 2014Co-Authors: Shi Tao-taAbstract:Research Online Mobile is one of many applications for Duckling, considering of its low bandwidth, long delays and frequent disconnection under mobile communication environment, it leads to conflicts easily when multiple users operating on the same Data, so conflict resolution and Data Synchronization are the key issues in Research Online Mobile. Aiming at this problem, this paper proposes a Data Synchronization strategy based on conflict resolution. It presents the overall framework and the strategy of Data Synchronization, and the conflict resolution process. Moreover, according to the scenes of conflict, the pushing model is established based on the user's classification and the priority. It creates a protocol on the Android platform and carries out experiments taking team contacts in Research Online Mobile as an example. The results show that this strategy can effectively save the bandwidth, improve the Synchronization efficiency and has good user experience.

Development of Value-added Services Based on Data Synchronization
Computer Engineering, 2009Co-Authors: Feng Mei-laiAbstract:The paper introduces the SyncML protocol,focuses on the implementation of a Data Synchronization system which is based on SyncML protocol,combines the features of the client and server,and gives the idea of the implementation. The client(mobile phone) uses the development language of J2ME. The server uses the tomcat which is based on the J2EE architecture and the free open-source project of the Funambol Data Synchronization architecture,and analyses the function and characteristics of the implementation and the virtue of ideas.

An improved fragmentation approach to sampled-Data Synchronization of chaotic Lur’e systems
Nonlinear Analysis: Hybrid Systems, 2018Co-Authors: Junmin Park, Seok Young Lee, Poogyeon ParkAbstract:Abstract This paper considers the sampled-Data Synchronization problem for two identical chaotic Lur’e systems. Under aperiodic samplings, the output of the chaotic Lur’e systems is available only at sampling instants. An improved fragmentation approach addresses a system description of the fragmented state located between the last sampling instant and present time. The sampled output of the fragmented state system is updated only at sampling instants, like the identical chaotic Lur’e systems. Thus, utilizing the additional information on the fragmented state system helps in handling the sampling interval. In the looped-functional framework, a sampled-Data Synchronization criterion is proposed for stability analysis and control synthesis about stabilization in terms of linear matrix inequalities. Simulation results show the effectiveness of the proposed criterion.
