Emergence is seen as the most significant feature discriminating " complex " from " non complex " systems. Nevertheless, no standard definition of emergence is currently available in the literature. This lack of a shared view affects the development of tools to detect and model emergence for both scientific and engineering applications. Here we review some(More)
Complex Systems Science aims to understand concepts like complexity, self-organization, emergence and adaptation, among others. The inherent fuzziness in complex systems definitions is complicated by the unclear relation among these central processes: does self-organisation emerge or does it set the preconditions for emergence? Does complexity arise by(More)
A thoracic artificial lung (TAL) was designed to treat respiratory insufficiency, acting as a temporary assist device in acute cases or as a bridge to transplant in chronic cases. We developed a computational model of the pulmonary circulatory system with the TAL inserted. The model was employed to investigate the effects of parameter values and flow(More)
Dr Fabio Boschetti describes himself as an applied mathematician. For many years his work focused on geoscientific applications. More recently he started to be interested in Complex System Science and to apply his past experience to ecological modelling with a view to improve our understanding of how ecosystems and their interaction with human activities(More)
We use an Interactive Genetic Algorithm to optimise the input parameters controlling the behaviour of a Cellular Automata. We aim to deduce which combination of parameters allow the CA to reproduce patters seen in geological scenarios as a result of fluid flow and chemical reaction in fractured media. Via the Interactive Genetic Algorithm the user can(More)
The Green's function of the Poisson equation, and its spatial derivatives, lead to a family of wavelets specifically tailored to potential fields. Upward continuation of the field is seen to be identical to these wavelets' scale change operation. The maxima at all heights of the field's horizontal gradients are termed the field's multiscale edges. A(More)
We propose a set of criteria which are based upon spatial relations between geological structures, in order to develop a measure of similarity between geological sections. By giving different weights to the criteria, the technique can be tuned to different geological problems. The weights are determined automatically when a user ranks sets of test images,(More)
The social context of an agent can have a profound influence upon their decisions and actions, where their attitudes and ideologies frequently change the interpretation given to a specific body of knowledge. However, attitudes and ideologies themselves result from groups of agents as they communicate and respond to information. This paper proposes a(More)
We utilise the well-developed quantum decision models known to the QI community to create a higher order social decision making model. A simple Agent Based Model (ABM) of a society of agents with changing attitudes towards a social issue is presented, where the private attitudes of individuals in the system are represented using a geometric structure(More)
Shifting the emphasis from a model to a modelling task, which involves both a computer model and a modeller, we ask what makes a problem complex. We propose that a modelling task can be seen as a set of questions-and-answers, nested at multiple levels. The role of the modeller then lies in posing the questions and choosing the best procedure to answer them,(More)
