We describe a networked teleoperation system that allows groups of participants to collaboratively explore live remote environments. Participants collaborate using a spatial dynamic voting (SDV) interface that allows them to vote on a sequence of images via a network such as the Internet. The SDV interface runs on each client computer and communicates with a central server that collects, displa...

ERP systems provide information management and analysis to industrial companies and support their planning activities. They are currently mostly based on theoretical values (averages) of parameters and not on the actual, real shop floor data, leading to disturbance of the planning algorithms. On the other hand, sharing data between manufacturers, suppliers and customers becomes very important t...

This paper addresses a method to solve a node discovery problem in a complex network. Covert nodes which exist in a social network do not appear in the records which are observed on the communication or collaborative activities among the nodes. Discovering the covert nodes refers to identifying suspicious records in which the covert nodes would appear, or suspicious nodes which would be the nei...

The assessment of value systems alignment can play an important role in the formation and evolution of collaborative networks, contributing to reduce potential risks of collaboration. For this purpose, an assessment tool is proposed as part of a collaborative networks information system, supporting both the formation and evolution of long-term strategic alliances and goal-oriented networks. An ...

Networked Collaborative Virtual Environments (NCVE) have been a hot topic of research for some time now. However, most of the existing NCVE systems restrict the communication between the participants to text messages or audio communication. The natural means of human communication are richer than this. Facial expressions, lip movements, body postures and gestures all play an important role in o...

The paper proposes a hierarchical, agent-based, DES supported, distributed architecture for networked organization control. Taking into account enterprise integration engineering frameworks and business process management techniques, the paper intends to apply control engineering approaches for solving some problems of coordinating networked organizations, such as performance evaluation and opt...

In this paper we critically review and analyze previous research on collaborative concept mapping in both face-to-face and networked environments. Although research has shown the positive effects of collaborative concept mapping on learning in face-to-face learning environments, there is a dearth of research which specifically focuses on the potential value of adopting collaborative concept map...
