♣ ♣ ♣ ♣ Nowadays, many organizations form dynamic partnerships to deal effectively with market requirements. As companies use automated workflow systems to control their processes, a way of linking workflow processes in different organizations is useful in turning the cooperating companies into a seamless operating virtual enterprise. The CrossFlow Esprit project aims at developing information ...

Virtual Campusis a research project which aims to provide a comprehensive and innovative e-learning environment for authoring, fruition and evaluation. The paper presents the Tutoring and Validation module developed for Virtual Campus. The Validation tool tracks the learners’ behaviour within the Virtual Campus environment and defines the “user model” in terms of learning attitudes (derived by ...

Agent system is an important technology to manage Virtual Information Space (VIS) and provide a variety of services to users on VIS. Especially, multiple agents can solve highly complex problems in manners of collaboration and cooperation based on knowledge, intelligence, and semantics. In particular, Virtual Organizations (VOs) are applied to several domains, e.g., e-learning, e-business, and ...

When implementing multi-user cooperation systems in networked virtual environments, synchronizing local representations of shared virtual world has to be considered. It involves distributing and storing the data that represent users’ activity in the virtual world. In this paper we propose a concept of general variables, which formalizes the task of distributing, journaling and locking the data ...

As cooperation between robots and humans becomes increasingly important for new robotic applications, human-robot interaction (HRI) becomes a significant area of research. This paper presents a novel approach to HRI based on the use of a virtual surface. The presented system consists of a virtual surface and a robot manipulator capable of tactile interaction. Multimedia content of the virtual s...

Patient's active cooperation is essential to achieve good outcome in pediatric rehabilitation. Therefore, virtual environments were developed to enhance robotic assisted gait training. The purpose of this study was to evaluate virtual realities as motivational tools during robotic assisted gait training with children in the pediatric Lokomat®. Nine children with different gait disorders and eig...

Nowadays, organizations aiming to be successful in an increasingly competitive market tend to group together into virtual organizations. Designing the information system (IS) of such virtual organizations on the basis of the IS of those participating is a real challenge. The IS of a virtual organization plays an important role in the collaboration and cooperation of the participants organizatio...

Transnational crime, sometimes called international crime or multinational systemic crime, is more than an extension of domestic crime. In the context of globalization, transnational organized crime groups respond to market incentives and operate with cooperative relationships, which makes the multinational criminal systems become more efficient and powerful.
