The volumes of data in information systems are growing drastically. The systems become increasingly complex in trying to handle heterogeneity of ubiquitous components, standards, data formats, etc. According to the vision of Autonomic Computing, the complexity can be handled by introducing self-manageable components able to "run themselves." Agent Technology fits this vision, whereas interoperability...
This research develops interaction models among companies in IC supply chain to study the information integration among them. The main processes of IC supply chain are IC design, wafer fabrication, wafer probe, IC packaging/assembly, and final test. A workflow model between IC design houses and wafer fabrication plants is developed with focuses on purchase order, engineering data, and work-in-process...
The priority of universities and colleges is to develop students' practical capability, creative capability, career capability as well as the capability to initiate a business. As a fundamental course in management major, management science is supposed to have certain features stressing the development of applied talents in the arrangement and design of its educational activities, namely, aimed to...
Data conversion between different data sets is an important research issue in computer science. Because of its computational complexity and demand for high accuracy, many data conversion problems arising in application can not be solved effectively. Based on the analysis of construction method, a new bijective function hn from natural numbers set N and its n-ary Cartesian product set Nn has been proposed...
With the information from the survey of IT system made by applied statistics Research Centers of Renmin University of China, this research places much emphasis on analyzing the status and problems of building and managing IT system by such statistics models as cluster and correspondence analysis, and gives some advices on how to manage and build IT system.
In order to adapt to a dynamically changing world, business organization focuses on its core competencies and collaborates with other companies to develop new products.

The purpose of the paper is to describe a set of variables able to show the level of propensity to innovate. In order to evaluate innovation, the authors built a model with different variables that can help management to measure the level of innovation in their company. The model is based both on theories about innovation and on the authorspsila expertise. A questionnaire was prepared with the aim...
The requirement for small satellites has been on a rise ever since 1957. The clients are spread far and wide on the globe. They have diversified requirements for payloads and are also limited by budgets for these satellites. These aspects tremendously increase pressure on design and development teams from translating abstract specifications to detailed designs to meet customer requirements. Ongoing...
Paragon Space Development Corporation (Paragon) has been honored by NASA as a ldquoHallmark Success Storyrdquo due to our ability to incorporate radiator development technology into the Orion Program winning bid by Lockheed Martin. The Paragon Dive Systemtrade used for contaminated-water diving, currently being manufactured for the Navy, was also named one of the ldquoTop 10 Inventionsrdquo of the...
The following paper presents the experience gained from a large scale software migration project.It describes how the migration strategy was selected and how the project was planned. It emphasizes the importance of keeping the costs as low as possible. It then goes on to outline the methods and techniques used in the migration with special emphasis on the migration process.

In the recent decades most of the big organizations have adopted maturity driven process improvement efforts (MDPI). Most of these efforts have been inspired of maturity models like the CMM (capability maturity model). The maturity of an organizationpsilas processes is measured through its maturity level. An organization availed a high maturity level is considered more trustworthy In this competitive...
We present SoQL (social networks query language), a new language for querying and creating data in social networks. The language is designed to meet the growing need of social networks participants to efficiently manage the large, and quickly growing, amounts of data available to them, as well as automate processes of creating new data. This need is increasingly pressing as social networks gradually...
Duplicate records are a major problem and duplicate invoices are a specific example of this. The detection of duplicate invoices is a critical issue for business since duplicate invoices can result in a company paying more than once for goods or services ordered. Past experience has shown that generic duplicate record detection techniques are not very useful when applied to invoices: the rate of false...
As the development of China's market economy, powerful construction companies in developed countries have gained the access to Chinese construction market, and traditional construction industry has been in a more competitive case, construction companies must continue to improve their core competitiveness in order to survive and develop in fierce competition, information technology is the important...
This paper summarizes work performed to develop new types of charts for the visualization of statistics associated with client service events: the matrix bar chart and the flower bed chart. In the problem that led to these charts, we had to visualize time series data of service events sequence related to specific clients. The flower bed and matrix bar charts can be plotted for any specific interval...
Governance of IT is becoming more and more necessary in the current financial economic situation. One declination of that statement is the definition of corporate and IT policies.
