Firstly, mutual information measure is combined with morphological gradient information. The essence of the gradient information is that locations a large gradient magnitude should be aligned, but also the orientation of the gradients at those locations should be similar. Secondly, a hybrid optimizer combined PSO with Powell algorithm is proposed to restrain local maxima of mutual information function and improve the registration accuracy to sub-pixel level. Lastly, muhlresolution data structure based on Mallat decomposition can not only improve the behavior of registration function, but also improve the speed of the algorithm. Experimental results demonstrate that the new method can yield good registration result, superior to traditional optimizer with respect to smoothness and attraction basin as well as convergence speed. 展开更多

Our study deals with two major issues impacting current WebGIS development: interoperability of heterogeneous data and visualization of vector data on the Web. By using the combination of Geography Markup Language (GML), Scalable Vector Graphics (SVG) and Web Feature Service (WFS) Implementation Specifications developed by the OpenGIS Consortium (OGC), a strategy of WebGIS is proposed. The GML is used as a coding and data transportation mechanism to realize interoperability, the SVG to display GML data on the Web and the WFS as a data query mechanism to access and retrieve data at the feature level in real time on the Web. A case study shows that the combination mentioned above has enormous potential to achieve interoperability while not requiring considerable changes to existing legacy data. Original data formats need not be changed and could still be retrieved using WFS and transformed into GML in real time. SVG can oroduce suoerior ouality vector maps on a Web browser. 展开更多

It is not a new field of study in the sense that it requires an entirely new ethical thinking. 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

Organizations serving rural communities in Kenya have found use for media as a tool of replacement for personal interface in the daily communication with the beneficiaries of their programmes in deprived areas. The interactions between two non-governmental organizations (NGOs) and rural beneficiaries in Isinya, Kajiado County, provide case studies of how NGOs modernize their outreach via new media and how beneficiaries respond to the change. The research was not only concerned with the presence of information technology (IT) and online facilities in remote and deprived locations. It also evaluated responses to the replacement of person-to-person contact with technologies, such as social media, the Internet, Compact Disc-Read Only Memory (CD-ROMs), and Digital Versatile Disc (DVDs). Conducted in four focus groups, the research evaluated the uptake of new media technologies by beneficiaries following the transition, asked whether beneficiaries engaged with the materials being communicated, and assessed whether this confluence of technology and culture had eased the flow of communication, or unsettled it. Evidence of discomfort among the older (over 50-year-old) beneficiaries stemmed from fear of failure to master the technologies and a desire for a continuation of regular interpersonal interaction with the NGO field officers (whose field trips were scaled back in preference of computer-mediated communication). However, younger (under 40-year-old) beneficiaries were less insistent on regular interpersonal visits and were appreciative of the use of technology, and of the building of Maarifa Centres to give the beneficiaries free access to internet, DVDs, and hard drive-based information materials. Another demographic, beneficiaries aged between 40 and 50 years old, said they were not comfortable with the change and wanted the interpersonal interaction to continue, but were open to a longer-term transition once the beneficiaries were all conversant with the uses of the new technologies. The study recommends a better managed transition that accommodated the beneficiaries’ fears, misgivings, and cultural preference for verbal, face-to-face consultation. 展开更多

In this paper, we conduct research on the O2O mode and corresponding influence on the online and offline Internet marketing. Precision marketing is on the basis of fully understanding of consumer information, according to its characteristics and primary preferences targeted to carry out the one-to-one marketing. Mobile Internet users are mostly fixed which can be the new network technology in-depth insight into consumer interest and demand, and to establish for each specific customer database. Based on the analysis of customer data, then according to the characteristics of the different customers and the preference information such as the precision marketing, at the same time which can also according to customer' s feedback information targeted adjustment of products and the marketing, in order to better meet the needs of customers. Our research combines the O2O concepts and the technique to propose the novel marketing paradigm which is of great importance. 展开更多

Internal control is a hot topic at present academics and for practitioners to explore. Especially under the background of China' s rapid integration into the global economy, the rapid establishment and improvement of the context of the modem enterprise system, the issue is of utmost importance. The internal accounting control system is the core part of internal control, which determines the extent of establishing the entire sound internal control system, With the progress of the time, the rapid development and wide application of Internet technology has changed the survival environment and management philosophy for business. The development of network technology achieves the online office, mobile office and decentralized offices, etc. Accounting entity is no longer subject to space limitations of traditional methods, thus a large number of accounting information is transmitted tbaough the network communication lines, so that accounting activities can be extended to every node in the world, which achieves the purpose of remote processing. Under the network environment, sources of information are of diversity and multi-channel. A large number of accounting information transmitted from the network communication lines is likely to be illegally intercepted, stolen and tampered by molecules or people with ulterior motives. 展开更多

Along with worldwide Internet boom, China's Internet industry is also thriving and has achieved remarkable success. Beyond that, industry integration between the Internet and other fields, such as finance, retail and advertising, is also eye-taking, as it has fostered a novel industry chain structure and business model. With an aim to realize the transformation and upgrading of conventional industry, the Chinese government has proposed ‘Internet plus' to encourage the combination of the Internet and conventional sectors. As one of the most important and complex conventional industries, the oil and gas(O&G in abbreviation) industry is also seeking the opportunity to actively cooperate with the Internet. However, after analysis of the differences between the particularities of the O&G and Internet industry from an economics perspective, a comprehensive combination of these two seems less promising, but adopting Internet related technologies to improve the performance of the O&G industry is feasible. 展开更多
