Meta-information generation in distributed information system

The authors discuss the concept of meta information which is the description of information system or its subsystems, and proposes algorithms for meta information generation. Meta information can be generated in parallel mode and network computation can be used to accelerate meta information generation. Most existing rough set methods assume information system to be centralized and cannot be applied directly in distributed information system. Data integration, which is costly, is necessary for such existing methods. However, meta information integration will eliminate the need of data integration in many cases, since many rough set operations can be done straightforward based on meta information, and many existing methods can be modified based on meta information.

Intelligent Resources Management System Design in Information Centric Networking

Information centric networking(ICN) is a new network architecture that is centred on accessing content. It aims to solve some of the problems associated with IP networks, increasing content distribution capability and improving users' experience. To analyse the requests' patterns and fully utilize the universal cached contents, a novel intelligent resources management system is proposed, which enables effi cient cache resource allocation in real time, based on changing user demand patterns. The system is composed of two parts. The fi rst part is a fi ne-grain traffi c estimation algorithm called Temporal Poisson traffi c prediction(TP2) that aims at analysing the traffi c pattern(or aggregated user requests' demands) for different contents. The second part is a collaborative cache placement algorithm that is based on traffic estimated by TP2. The experimental results show that TP2 has better performance than other comparable traffi c prediction algorithms and the proposed intelligent system can increase the utilization of cache resources and improve the network capacity.

Real-time traffic information extraction based on compressed video with interframe motion vector

Extraction of traffic information from image or video sequence is a hot research topic in intelligenttransportation system and computer vision. A real-time traffic information extraction method based on com-pressed video with interframe motion vectors for speed, density and flow detection, has been proposed for ex-traction of traffic information under fixed camera setting and well-defined environment. The motion vectors arefirst separated from the compressed video streams, and then filtered to eliminate incorrect and noisy vectors u-sing the well-defined environmental knowledge. By applying the projective transform and using the filtered mo-tion vectors, speed can be calculated from motion vector statistics, density can be estimated using the motionvector occupancy, and flow can be detected using the combination of speed and density. The embodiment of aprototype system for sky camera traffic monitoring using the MPEG video has been implemented, and experi-mental results proved the effectiveness of the method proposed.

The results from this study highlight that the income of a disabled person, awareness about the information and technology, interest of new technology usage, social and cultural background of a person, use of English language in day-to-day life give a significant impact on the adoption oflCT by the disabled community.

The extent of voluntary disclosure in an emerging capital market： The case of Jordan

This study evaluates the extent of voluntary disclosure in the annual reports of non-financial companies listed at the Amman Stock Exchange （ASE） for the year 2006. The study adopts the disclosure index suggested by Haddad, AI-Shattarat ＆ Nobanee （2009） and evaluates the voluntary disclosure for the Jordanian companies for the year 2006 at three levels： the first provides a description and analysis of the overall voluntary disclosure; the second covers the extent to which each individual item of information is disclosed; the third covers the type of information （e.g., financial information, historical information, management discussion）. The results of the study reveal that there was a considerable variation in the disclosure of the index items and also among the listed companies. On average, a company disclosed about 28.95% of the items applicable to it, and only six out of the 53 companies received disclosure scores greater than 50%. It was also found that 50 items out of 62 items included in the index had a disclosure below 50%, and 10 items had disclosure of less than 10%. With respect to the evaluation of different types of information, the analyses indicated that the category of the background information, the category of financial ratios and the category of management discussions were better disclosed in corporate annual reports than the other types of information.
