The advancement in computer technologies and the transference of these technologies to simulators for medical education continues to be a driving force in medical education. The complexities of surgical training and the emergence of minimally invasive surgery (MIS) as a primary surgical mode have pushed the surgical simulator to the forefront of surgical education. Simulators are now developed by...
In this paper we present an hybrid architecture for a computer supported collaborative work in pervasive computing environment simulator. This architecture supports pure simulation mode where all agents are simulated, real deployment where it seamlessly integrates pervasive computing to the computer supported collaborative work and finally an hybrid mode where real devices can interact with simulated...
Cloud Computing is becoming one of the most important topics in the IT world. Several challenges are being raised from the adoption of this computational paradigm including security, privacy, and federation. This paper aims to introduce new concepts in cloud computing and security, focusing on heterogeneous and federated scenarios. We present a reference architecture able to address the Identity Management...
Despite several attempts to accurately predict duration and cost of projects, simulation models in use are still over simplified and nonrealistic. They often fail to cope with real-life scenarios and uncertainty. In this paper we use the proxel-based simulation method to analyze and predict duration of project schedules exhibiting high uncertainty due to typical on-the-fly human decision behavior...
This paper identifies and characterizes several important impediments to reusable agent-based models. It describes a new class of programming languages that address these problems by allowing abstract specification of incomplete but accurate models and by enabling automated construction of agent-based simulations from models. The primary innovation underlying this approach is the use of property-based...
The present study describes the migration and coupling of a monthly conceptual rainfall runoff model named UTHBAL and a water reservoir operation model called UTHRL into the OpenMI standard. The models have been introduced by Loukas et al.. We have developed a collaborative decision support framework named UTH-MODELER which automates the migration of the two models into OpenMI. This framework synchronizes...
