Teleradiology, which enables distribution and sharing of digital medical images for collaborative diagnosis, has enjoyed rapid success due to the advances in telecommunication and multimedia technologies. However, the interactive collaboration mechanisms that control the editing among multiple users on the same object is often limited to simple ‘locking’ concept, where only one user edits an ob...

Secure energy and transport networks, Internet and telecommunications, are vital nerves of our highly networked society. Global mobility makes it difficult to combat and natural disasters and technological accidents can cause serious damage in a closer-knit world. In this paper we introduce the challenges in dynamic community composition of heterogeneous rescue forces (culture clash) for rescue...

IEEE Control Systems Magazine February 2001 Feedback control systems wherein the control loops are closed through a real-time network are called networked control systems (NCSs) [1]-[4]. The defining feature of an NCS is that information (reference input, plant output, control input, etc.) is exchanged using a network among control system components (sensors, controller, actuators, etc.). Fig. ...

When dealing with networked systems, the concept of controllability refers to the possibility of controlling the overall state of a group of agents by providing an external input only to a subset of them, that are referred to as leaders. On the same lines, the concept of observability is related to the possibility of observing the whole state of the networked system from only a subset of the ag...
