The Rock-Paper-Scissors(RPS) game is a paradigmatic model for cyclic dominance in biological systems. Here we consider this game in the social context of competition between opinions in a networked society. In our model, every agent has an opinion which is drawn from the three choices: rock, paper or scissors. In every timestep a link is selected randomly and the game is played between the node...

This paper describes the research design of an ongoing case study in an apartment complex comprising approximately 160 international students in Brisbane, Australia. The objective of the study involves the design and development of an online community network to facilitate the creation and growth of a sustainable residential neighbourhood community. The study is informed by the PAD methodology ...

Active Knowledge Engineering Lab The Active Knowledge Engineering Lab activities include investigations that are about discovering, externalizing, expressing, representing, sharing, exploring, configuring, activating, growing and managing enterprise knowledge as well as designing new programming platforms based on mentioned above principles. This year we have been focused on the following topic...

Execution of an interactive collaboration application or a distributed game involves many individual multimedia applications that concurrently generate and/or play back several audio and video streams. As the resource requirements of individual streams change and as streams/applications are started or later terminated, the amount of available resources may change dynamically. Networked MultiMed...

The quality of communication processes in networked organizations is difficult to evaluate and improve, because of the many parties involved in meaning construction and responsibility assignment. This paper presents an outline of a communications quality model grounded in semiotics that can be used to construct a quality management system. Key elements of any such system are quality perspective...

Wireless networked control systems (WNCS) consist of an actuator, sensor, and controller communicating over wireless networks in place traditional point-to-point wired connection. Due to their main advantages, a decrease maintenance costs, more flexibility, safety could be achieved. As result, it attracted great deal interest, but packet losses time delays the network through transmitting recei...

We study a networked state estimation problem for a linear system with multiple sensors, each of which transmits its measurements to a central estimator via a lossy communication network for computing the minimum mean-square-error (MMSE) state estimate. Under a general Markov packet loss process, we establish necessary and sufficient conditions for the stability of the estimator for any diagona...

Stability and performance of networked control systems has been a recent area of interest in the control literature. The inclusion of a shared communication network between plant and controller inevitably leads to occasional random data loss. We provide novel results relating to the probability of such a system being globally asymptotically stable or input to state stable. Copyright c ©2005 IFAC
