Dynamics for a discrete competition and cooperation model of two enterprises with multiple delays and feedback controls

Lin Lu, Yi Lian, Chaoling Li

Open Mathematics > 2017 > 15 > 1 > 218-232

This paper is concerned with a competition and cooperation model of two enterprises with multiple delays and feedback controls. With the aid of the difference inequality theory, we have obtained some sufficient conditions which guarantee the permanence of the model.

A fundamental goal of datacenter networking is to efficiently interconnect a large number of servers in a cost-effective way. Inspired by the commodity servers in today’s data centers that come with dual-port, we consider how to design low-cost, robust, and symmetrical network structures for containerized data centers with dual-port servers and low-end switches. In this paper, we propose a family...

Crystal Research and Technology > 48 > 5 > 265 - 272

ZnO thin films with different Mg doping contents (0%, 3%, 5%, 8%, 10%, respectively) were prepared on quartz glass substrates by a modified Pechini method. XRD patterns reveal that all the thin films possess a polycrystalline hexagonal wurtzite structure. The peak position of (002) plane for Mg‐doped ZnO thin films shifts toward higher angle due to the Mg doping. The crystallite size calculated by...

Pengxu Tan, Yue Chen, Chaoling Li

2013 IEEE 4th International Conference on Software Engineering and Service Science > 507 - 510

2013 IEEE 4th International Conference on Software Engineering and Service Science (ICSESS)

Regenerating code is a fault-tolerant technique based on the network coding. However, most of the researchers just focus on the construction of the codes, ignoring the security of the codes in application, especially the security in an extremely open environment such as cloud computing and cloud storage. A secure regenerating code, called SRCS is proposed in this paper to solve the fault-tolerant...

Towards comprehensive provable data possession in cloud computing

Chaoling Li, Yue Chen, Pengxu Tan, Gang Yang

Wuhan University Journal of Natural Sciences > 2013 > 18 > 3 > 265-271

To check the remote data integrity in cloud computing, we have proposed an efficient and full data dynamic provable data possession (PDP) scheme that uses a SN (serial number)-BN (block number) table to support data block update. In this article, we first analyze and test its performance in detail. The result shows that our scheme is efficient with low computation, storage, and communication costs...

2012 International Conference on Business Computing and Global Informatization (BCGIN)

In order to solve the Fault-Tolerant problem of the cloud storage system, the stream regeneration with regenerating codes is proposed. The stream regeneration is based on the regenerating codes with pipelined regeneration which evolves from regenerating codes theory. Stream regeneration extends the pipelined regeneration. It was proved that with the same participating nodes, the total amount of network...

An Efficient Provable Data Possession Scheme with Data Dynamics

Chaoling Li, Yue Chen, Pengxu Tan, Gang Yang

2012 International Conference on Computer Science and Service System > 706 - 710

2012 International Conference on Computer Science and Service System (CSSS)

Ateniese et al proposed an efficient Provable Data Possession scheme which uses only hash and symmetric-key cryptographic functions, but it cannot support block insertion. To achieve full data dynamics, a SN-BN table which maps the logical indices of blocks to their physical ones is introduced. The SN (Serial Number) is used to determine which blocks are included in tags, while the corresponding BN...
