In the paper, the genetic algorithms were employed to solve the weighting of the radial basis faction networks in order to improve the precision of remote sensing image classification. The remote sensing image classification was also introduced for the GIS spatial analysis and the spatial online analytical processing (OLAP), and the resulted effectiveness was demonstrated in the analysis of land utilization variation of Daqing city.展开更多

The constructivist theory and modern information technology are two pivot multimedia teaching system. Only to unite the two together as one, it can form a reasonable and effective teaching system. Accordingly, this paper discusses the theory of multimedia teaching, design and multimedia network technology of a modem information technology education in English teaching and other related issues.展开更多

G-STEP （GMES--space technology exchange partnership） is the University of Leicester＇s flagship project for innovation, training and education in GMES （global monitoring for environment and security） and GIS （geographical information systems） based technologies. G-STEP （part funded by the ERDF） is the first GMES accelerator initiative in the UK and is breaking new ground in the application of GMES and GIS. The core G-STEP team initiates and develops Knowledge Exchange Practices between the University and Life Long Learning partners in the East Midlands Region, through training packages and collaborative research projects. The programme integrates innovative research, to direct downstream applied training, supported by analytical processing of attendee assessment data. Collated information derived from these sources presents a unique opportunity to incorporate a statistically viable feedback cycle, making G-STEP the interface between pure and applied research, thus initiating downstream dissemination to groups and small business. In this paper, we outline the GMES and GIS training packages, and the route to market to increase uptake of underused data streams via university and regional entrepreneurs （start-ups） and established small business with a core interest in utilisation and dissemination of novel technologies in sustainable lifelong learning.展开更多

Rather, it is a field where we can try to use our traditional philosophical notions and apply them to this field of computer technology, information science, and knowledge society in order to define responsibility and accountability. Although relations of causalities may be blurred and complex because of the auto-poetic development of computers and information systems we may still have to face the fact that human beings are fundamentally responsible behind the responsibilities of the computers. So we can say that the concept of reliability and accountability is related to human responsibility in the field of Internet technology. Indeed, issues of hacking, viruses and intervention in computers also pose the problems of responsibility and violation of property and copyrights and here we face similar issues as when we talk about physical property rights although what happens is going on in cyberspace. Also we face fundamental problems about transparency, power and democracy of society as the result of the information revolution in knowledge. This shows how it becomes more and more difficult for governments and organizations to hide information and that information is becoming more and more public. We can also talk about the present development as a technology-driven information revolution in knowledge society. The information overload is a result of this revolution that is expressed in the Internet and that changes the relation of human beings to society where human beings need to access information technology and tools in order to be able to live and work in society.展开更多
