Digital watermarking is an effective and popular technique for discouraging illegal copying and distribution of copyrighted digital image information. One of the important features of the watermarking technique is the robustness of the watermarked image, which will preserve the quality of the retrieved watermark. There are two parts about robust oblivious watermarking scheme based on the frequency...
Component-based configuration management is an important supporting activity of the software development management and software quality control. Based on the research of CMMI and IEEE criterion, this paper presents the 3C (control, configuration, component) model which based on the component-based and layered architecture. As a sub-model of software quality management and software process model (Mingzhi...
Enterprise now urgently expects to utilize its proliferating unstructured information resources to improve its competitive capability. In order to manage unstructured information resources effectively, some kinds of technologies, such as natural language processing, intellectualized text analyzing, knowledge management and so on, should been synthetically applied and some especial demands, such as...
The increasing use of multi-database technology has led to the development of many multi-database systems for real-world application. Large companies may have to confront the multiple data-source problem,so multi-database mining has been an important research area. Negative association rules (NARs) play important roles in decision-making. But nowadays the techniques of NARs mining focus on mono-database...
Generally, every Website provides its own resource upload and download modules for users to share resources. However, the resources uploaded to Websites' servers are often lack of unified and professional management. Whatpsilas more, when the amount of user using the upload and download modules increases, it will put a big pressure on the Websitepsilas server in term of bandwidth. To solve these problems,...
Workflow management systems have been applied in enterprises for many years in collaborative environment to assist individuals or organizations to carry out tasks automatically and effectively. As market requirements are developing rapidly, the enterprises now find the traditional workflow management system under such rapid circumstances difficult to copy with changes in the market both promptly and...
Recently, Web Service technology has found its application in workflow management for supporting loosely coupled E-business processes. However, current Web services languages do not permit to describe distributed E-business services by lack of expressive power and formal semantics. This paper presents a novel method for modeling distributed E-business service composition with pi-calculus technology...
It explains the hierarchical architecture of Bluetooth technology, and states its technological characteristics and application environments. On this basis, the author proposed the method of replacing the wired communication medium with the Bluetooth wireless communication technology, as well as constructing a wireless manufacturing network under industrial environment. It is to realize wireless communication...
Manufacturing industry is challenged with the task of mass customization in a timely and cost-efficient manner. Knowledge Management (KM) can provide a new approach needed to manage intellectual capital as a valuable organizational resource for supporting customized preferences, so a framework of knowledge management for Mass Customization (MC) was developed. Knowledge management makes mass customization...
In order to facilitate the multi-dimension on-line analysis processing (MOLAP) on multi-dimension data warehouse and to support the port management decision, in this paper, we built the port production data cube with the port data, and then we stored the binary coded hierarchical dimension information with the dimension hierarchy storage tree. Based on that, this paper also proposed to create a dimension...
As Web services are the hotspot technology in heterogeneous application, Web services distributed management (WSDM) specification is being the focus one in the management domain. With its well-defined and extensible manageability capabilities applied for various network resources, we improved our originally proposed TcpSocket-based Topology Management System (TMS) in distributed WAN. Under the Ethernet...
In IEEE 802.16e system, mobile station (MS) is usually powered by battery. To save the limited power, IEEE 802.16e standard specifies sleep mode operation for power management.There are two significant performance factors in sleep mode operation, one is energy consumption, and the other is response delay. When MS wakes up by outgoing data frame from itself, only energy consumption is considered because...
