Internet Marketing can help companies get more traffic to their website and extend their business reach. Taking one language training centre named as Zhuhai New-Concept Training Centre (ZHNCTC) as an example, this paper details some Internet marketing tactics, including approaches to increase website traffic, methods to improve the "time on site" and "pages viewed", proposed activities to drive more sales from existing customers and some relevant evaluation methods. The paper also puts forward some recommendations about successful implementation of these Internet marketing tactics.

A novel Quantum-behaved Particle Swarm Optimization algorithm with probability (P-QPSO) is introduced to improve the global convergence property of QPSO. In the proposed algorithm, all the particles keep the original evolution with large probability, and do not update the position of particles with small probability, and re-initialize the position of particles with small probability. Seven benchmark functions are used to test the performance of P-QPSO. The results of experiment show that the proposed technique can increase diversity of population and converge more rapidly than other evolutionary computation methods.

Cyber physical systems have many non-functional requirements, which always crosscut the whole system modules. That may cause the code tangle and scatter, make the systems hard to design, reuse and maintain, and affect performance of systems badly. AOP is a new software development paradigm, which could attain a higher level of separation of concerns in both functional and non-functional matters by introducing aspect, for the implementation of crosscutting concerns. Different aspects can be designed separately, and woven into systems. In this paper, we propose a four-stage method of aspect-oriented MDA for non-functional properties to develop cyber physical systems. The model-based development, aspect-oriented approach and formal methods are integrated effectively for the development of the nonfunctional properties of distributed cyber physical systems. A case study illustrates the aspect oriented MDA development of cyber physical systems.

This paper presents a distributed fusion decision-making steganalysis method for attacking image steganography. The fusion rule of combination system likelihood function is derived based on the smallest error rate Bayesian decision-making rule. According to information fusion theory, by introducing fusion decision-making theory into steganalysis research, it will achieve more effective, more reliable and more stable steganalysis detection effect than just adopting a single local decision-making. The image characters are first extracted from spatial domain, DCT domain and DWT domain, and then the final result is obtained by using fusion rule. The simulation results show the fusion steganalysis method significantly improves the detection performance of local decision-making through introducing the fusion rule of combination system likelihood function.

The rapid development of computer network has greatly popularized online education, and the size of courseware is getting bigger. How to manage those resources is an urgent problem to be solved. This paper establishes a distributed courseware resource management system with P2P and CDN transmitting technology, providing highly concurrent VOD and distribution for numerous video courseware data, to meet the requirements of rising number of VOD users for online courseware. The system, like a huge memory, gives unified management for all courseware, and provides simple access interface. Meanwhile, the system provides management of users, authority, category and log, as well as searching, the administrator and students can look up the existing teaching scene and other references whenever and wherever possible.

With the rapid development of internet, the distributed file system is gradually facing problem of supporting concurrent 10K and 100K servers operations, so it now becomes an important issue that how to improve performance of the metadata server in high concurrent reading/writing environments. This paper designs and implements the distributed file system named RaccoonFS, researches and solves the problem of low response speed of name space management brought by the lock competition in distributed file system, and it proposes a new metadata name space management method that realized the technology of Copy-On-Write and Multi-Version Concurrency Control in B+ tree. Through the evaluation, the name space management that combined COW and MVCC in B+ tree greatly improved the read and write performance.

In a context of explosive development in Internet scale and excessive underutilization of a large number of network elements, the power consumption issues of the current Internet have become hot subjects extensively concerned by ICT (Information and Communication Technology) sector and research institutions in recent years, which even further lead to the severe economic issues and intractable environmental issues. On the basis of above circumstances, a distributed Power-saving Topology Management Scheme (DPTMS) is devised to achieve power saving for current Internet in the paper. After introducing the network model and power model, we describe the design of DPTMS including four modules: traffic prediction module, information awareness model, distributed topology decision-making module and sleeping control module. In the simulation and evaluation, DPTMS is compared with GRiDA as for network power consumption and network performance, which shows it is feasible and effective for a power-saving topology management.
