background and objective: co-authorship on writing articles is one of the indicators of reliability in scientific articles. due to the lack of information regarding to the rate of participation of the authors of articles in the ” iranian journal of pathology” this research with the aim of the survey of collaborative coefficients of article authors in this journal  from 2006 to 2012 was performe...

In this paper, we review the research findings in agent communication language (ACL). We then propose our model to develop an agent communication language based on the Foundation for Intelligent Physical Agents (FIPA) Standards. The use of communicative acts enables agents to recognize the intent of the requesting agents for a specific service. The ACL handles the semantics of information excha...

We describe the architecture and implementation of our comprehensive multi-platform collaboration framework known as Columbia InterNet Extensible Multimedia Architecture (CINEMA). It provides a distributed architecture for collaboration using synchronous communications like multimedia conferencing, instant messaging, shared web-browsing, and asynchronous communications like discussion forums, s...

This paper investigates the acceptability of using social media for collaborative learning in the context of higher education. A social media platform, Graasp, is used to support students’ learning activities in a project-based course. An evaluation of Graasp regarding its usefulness as a collaboration platform, a knowledge management site, and a gadget container, was conducted with the course ...

In this paper, we analyze the mutual information of sensor networks in an underwater wireless communication system by placing the acoustic sensor nodes at different location in order to achieve optimum mutual information. The performances of acoustic sensors nodes are observed and analyzed by placing the sensors in collaborative and parallel channel network system. Different numerical calculati...

Optimum arrangement of communication resources for a distance education system to support collaborative learning, including hand-manipulation of physical objects, was empirically investigated. The authors propose a ‘body metaphor’ concept, which follows the ordinary body arrangement in everyday instruction. It allows: (1) to display instructor’s pointer; (2) to display instructor’s face; (3) to...

Real-time collaboration is being offered by multiple libraries and APIs (Google Drive Real-time API, Microsoft Real-Time Communications API, TogetherJS, ShareJS), rapidly becoming a mainstream option for webservices developers. However, they are offered as centralised services running in a single server, regardless if they are free/ open source or proprietary software. After re-engineering Apac...

As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...
