IntroductIon While there are many aspects to managing corporate knowledge, one key issue is how to disseminate corporate documents with appropriate context. Upon finding an article on a certain subject, for example the material properties of titanium, a reader is likely to be interested in related articles such as applications of titanium or manufacturing methods for titanium parts. Each relate...

One of the driving factors in IT development is the availability of cheap and efficient network technologies. The Internet is no longer used only as a medium for personal communication. Organizations start utilizing this technology to link existing applications and to create new ones. While traditionally systems were designed to respond to interactive user requests, they are now more and more a...

Wireless sensor networks constitute an emerging technology that has received recently significant attention both from industry and academia. On the one hand, there is an ever-widening range of attractive applications (e.g., disaster and environmental monitoring, wildlife habitat monitoring, target tracking, intrusion detection, security surveillance) sensor networks can be used for. On the othe...

Much climate data are available that can only be utilized if there is a flow of information to agri-business and farmers. As dissemination is the distribution of information, two-way communication channels are a necessity. The content of the message must be relevant to the decisions of the client. The process should involve the identification of climate sensitive decisions and interactions betw...

the principal goal of this research is the feasibility study of presentation electronic reference services in such centers. in this research, we apply measuring methods in different stages. through this way, we attempt to focus on special governmental information centers in tehran which use internet for acquisition and dissemination of information and also for reference services, methods of col...

In this paper, we present CodeDrip, a data dissemination protocol for Wireless Sensor Networks. Dissemination is typically used to query nodes, send commands, and reconfigure the network. CodeDrip utilizes Network Coding to improve energy efficiency, reliability, and speed of dissemination. Network coding allows recovery of lost packets by combining the received packets thereby making dissemina...

Knowing the information dissemination mechanisms of different media and having an efficient information dissemination plan for disaster pre-warning plays a very important role in reducing losses and ensuring the safety of human beings. In this paper we established models of information dissemination for six typical information media, including short message service (SMS), microblogs, news porta...

Epidemic protocols have demonstrated remarkable scalability and robustness in disseminating information on internet-scale, dynamic P2P systems. However, popular instances of such protocols suffer from a number of significant drawbacks, such as increased message overhead in push-based systems, or low dissemination speed in pull-based ones. In this paper we study push-based epidemic dissemination...

A research can also reveal the cooperative effectiveness of agencies such as evaluation will lead to discover the weakness and strengths for further improvement of this program. The present study was designed in 2009 especially to see the effectiveness of the working of agricultural extension staff as perceived by farmers in district Okara-Pakistan. The data were collected with the help of a sp...
