We present an overview of the Virtual Patient project at the University of Maryland, which is developing a cognitive model of humans experiencing various states of health and disease to be used in interactive simulations for physician training.

The information society has reached a new era of communication and knowledge management. Virtual communities are emerging as a requirement in this new information distribution scheme. We investigate the concept of virtual knowledge communities using an agent-based abstraction. In this field, there is a need for evaluating the performances and the quality of a global system resulting from the be...

Robotics is an important area not only in research and development but also from the perspective of industrial automation. As a result, increasing number of fundamental and advanced level robotics courses are being introduced in the undergraduate and postgraduate curricula, particularly in Mechanical and Electrical engineering streams. Robot kinematics is the cornerstone of such courses and it ...

Virtual heritage reconstructions usually focus on displaying architecture or artefacts, with virtual humans playing only minor roles. In the real world, however, such places are, or have been, populated. We introduce a virtual crowd into the real-time 3D reconstruction of a complex heritage edifice to increase the realism of the reconstructed scene. We create a virtual population of worshippers...

BACKGROUND Virtual worlds provide a promising means of delivering simulations for developing interprofessional health skills. However, developing and implementing a virtual world simulation is a challenging process, in part because of the novelty of virtual worlds as a simulation platform and also because of the degree of collaboration required among technical and subject experts. Thus, it can ...

Even though the noise issue in manufacturing is widely discussed from legal and health aspects, there is still no comprehensive method to simulate and analyze it. In this paper, a novel concept to investigate the noise level is proposed. Therefore a simulation method and the virtual reality (VR) implementation are involved. Acoustic measurements in real factory provide validation data for a rea...

Optimistic protocols designed for Parallel Discrete Event Simulation (PDES) rely heavily on the Global Virtual Time (GVT) calculation. Since the simulation uses large amounts of memory , the GVT is used to synchronize processes and discard obsolete system information. In this paper we present a new algorithm, the Continuously Monitored Global Virtual Time (CMGVT). Unlike others, this algorithm ...

Summarized sports simulation systems based virtual reality. The function include construction of virtual training scenarios, sports data capture, physiological and psychological data acquisition, action reproduce and training effectiveness icon analysis. The key technologies include physical and physiological modeling, virtual human animation, motion capture and real-time rendering and interact...

The paper describes a framework for transfer of models of virtual reality simulation of structural behaviour written in Virtual Reality Modelling Language (VRML) and JavaScript programming languages to a more suitable platform for engineering applications. The Open Inventor has been found to be the most appropriate platform for translation of results of virtual reality simulation of structural ...
