A new generation of real-time computer systems performs physically and logically decentralized mission management—such as semi-autonomous entities collaboratively performing manufacturing, maintenance, combat, etc. These entities must robustly accommodate significant run-time uncertainties in their application environment and system resource state, by being dynamically adaptive. In particular, ...

Despite their predominant application in robotics, the utility of methods for information fusion is not limited to sensor-based fusion tasks. The paper presents an information retrieval (IR) system for multimedia weather documents which makes use of linguistic fusion methods and a semantically rich retrieval model based on methods from fuzzy set theory. The computational problem of how to effic...

This article has its starting point in a large number of empirical findings regarding computer-mediated work. These empirical findings have challenged our understanding of the role of mediation in such work; on the one hand as an aspect of communication and cooperation at work and on the other hand as an aspect of human engagement with instruments of work. On the basis of previous work in activ...

In response to calls in the Information Systems literature to contextualize usage, we propose that measuring computer-based multitasking is essential to accurately describe and properly assess the manner in which people use Information Technology. To this end, we develop several multitasking metrics ranging from a very lean dichotomous variable to a very rich measure that combines user, task an...

this study aimed at investigating the impact of utilizing call on efl learners’ foreign accent reduction. to this end, 62 participants out of 100 undergraduate freshman english students at islamic azad university central tehran branch were ed based on a piloted sample pet and a text-to-read. the ed participants were then nonrandomly assigned to an experimental and a control group, each containi...

Whatever Media Studies 2.0 involves, one thing is certain, there is a need to confront and deal with new technologies, most notably computers and computer networks. Despite the fact that the discipline has largely marginalized these innovations, there has been some effort to incorporate the computer into both the theories and practices of media studies. This has been accomplished, at least in t...

Design representation is not only used to document the final design for construction; it is essential for the development and communication of design ideas. With recent developments in CAD and communications technologies, the way we represent and visualize designs is changing. In this paper we canvass the results of experiments examining the effect of different communication channels in collabo...
