It mainly focuses on fc estimation when fcmax and fcmin are not approximately equal to 100% and 0%, respectively due to using remote sensing image with medium or low spatial resolution. Meanwhile, we present a new method of fc estimation based on a random set of fc maximum and minimum values from digital camera (DC) survey data and a di- midiate pixel model. The results show that this is a convenient, efficient and accurate method for fc monitoring, with the maximum error -0.172 and correlation coefficient of 0.974 between DC survey data and the estimated value of the remote sensing model. The remaining DC survey data can be used as verification data for the precision of the fc estimation. In general, the estimation of fc based on DC survey data and a remote sensing model is a brand-new development trend and deserves further extensive utilization.展开更多

(VIP) and Beijing Wanfang Data Co., Ltd. (WFD), as subjects to discuss digital publishing mechanism innovations for China’s science information communication system. After introducing main Internet environment, comparing journal characteristics, and explaining publishing & operation modes of the IAJs, the paper analyses important issues such as redundant contents, digitalization issues, illegal journals, standards construction, copyright and benefit distribution. By learning from research practices and open access, a new benefit distribution and copyright management mode based on the Third Party Agency (TPA) is proposed. Future IAJs operation modes are also discussed from the view of scientific research innovation and state of the art platform construction.展开更多

What may come as a general challenge is the ＂performance＂ amateurs who have the devices, the will but not the skills to become reliable communicators. Good training and an expanded concern for the accuracy of messages should distinguish between fact and fiction, and between information and opinion. The smart phone, the iPod, the lap top, or the tablet has expanded the means of communication. They have also diversified the types of messages circulated. The traditional main stream media outlets are facing a mounting competition from the social networks populated with the folk journalists, albeit, and non-professionals. Basic training of all those willing to come into the communication ring and regulations may concern not only the professionals but also the amateurs, and it may be ways to get over what seems to be a deadlock.展开更多

A comprehensive tool is developed in the form of a test simulator. The simulator is capable of providing a required goal of test for the Circuit Under Test （CUT）. The simulator uses the approach of fault diagnostics with fault grading procedures to provide the optimum tests. The current version of the simulator embeds features of exhaustive and pseudo-random test generation schemes along with the search solutions of cost effective test goals. The simulator provides facilities of realizing all possible pseudo-random sequence generators with all possible combinations of seeds. The tool is developed on a common Personal Computer （PC） platform and hence no special software is required. Thereby, it is a low cost tool hence economical. The tool is very much suitable for determining realistic test sequences for a targeted goal of testing for any CUT. The developed tool incorporates flexible Graphical User Interface （GUI） procedures and can be operated without any special programming skill. The tool is debugged and tested with the results of many bench mark circuits. Further, this developed tool can be utilized for educational purposes for many courses such as fault-tolerant computing, fault diagnosis, digital electronics, and safe-reliable-testable digital logic designs.展开更多

Because of the multidimensional features of e-Journals, they are becoming the choice of academic as well as public library users. Technology, and particularly the Internet, has great potential for altering scholarly communication and research inhumanities, sciences, social sciences, and health sciences disciplines. Results of scholarly surveys show that there is a significant interest in e-Publication of research. Thus, this research paper investigates the attitudes and perceptions of faculty members at the University of Jordan (UJ) of current issues associated with the use of electronic publishing and perceived obstacles to their extended use for scholarly communication and publication. Specifically, the primary focus of this study is to examine and perceive how faculty members’ use of electronic publications might affect their interest in publishing their own research in electronic formats;as well as to determine the contribution of scholars towards publishing in e-Journals. In order to achieve the research objectives, a questionnaire method was adopted to elicit the opinions of the faculty members;whereas personal interviews were conducted to fill in the gaps. The results of the study reveal that the majority of the faculty members prefer to publish in electronic formats refereed journals, due to the advantages of publishing in e-Journals. Furthermore, the findings show that faculty members are also concerned about the disadvantages of e-Publishing. On the basis of the findings, some suggestions have been recommended to make publishing in e-Journals more acceptable to those scholars at UJ who still do not use it, as well as to maximize the use of e-Publishing because of the advantages that it may offer.展开更多
