application of ict in health (ehealth) has become an integral part of modern healthcare systems. elec­tronic health information management has proven useful in improving quality of health care, reducing costs and facilitating health research. however, the increasing complexity of healthcare and the growing demand for high quality healthcare delivery has created a need for ehealth systems with t...

in this article a graph theoretical approach is employed to study some specifications of dynamic systems with time delay in the inputs and states, such as structural controllability and observability. first, the zero and non-zero parameters of a proposed system have been determined, next the general structure of the system is presented by a graph which is constructed by non-zero parameters. the...

this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...

How does someone react when he faces a critical situation in his life? In this paper we present an agent-based model for simulating people’s behaviors in those particular situations. Coping strategies are at the heart of our model and we use some strategies developed in the area of psychology. We show the first step of our implementation architecture. We are currently implementing our model by ...

The science of complexity contains a plethora of models and ideas through which we can interpret and understand the world around us. Thus, we keep an eye on reality throughout, touching on the practical benefits of gaining an understanding of complex systems. Agent based modeling is a methodology that has been driving a lot of research in complex systems. In this work, we present how agent-base...
