Structural and dynamic complexities of risk and catastrophe systems : an approach by system dynamics modelling
2006
Cette publication figure en ligne à l'adresse suivante : http://www-lih.univ-lehavre.fr/~bertelle/cossombook/complex22.pdf; International audience; Risk and catastrophe are complex systems. Within thescope of this paper, we focus our attention on structuraland dynamic complexities of catastrophes and on thepossibility of modelling and simulating its doublecomplexity with a formal and methodological framework:the General Systems Theory and System Dynamicsmodelling. We then briefly propose a model of urbancatastrophe related to a flood. We then propose some waysof research allowing exceeding the limits related to themodelling.
Integrated thermodynamic and electrical modelling of a variable-speed reversible heat pump: analysis of the cooling mode operation
2022
Variable-speed reversible heat pumps are increasingly adopted for space heating and cooling in residential and tertiary sectors. It is recognized that these systems will play a key role in medium- and small-scale 4th generation district heating and cooling networks. Indeed, with the high penetration of intermittent renewable energy sources, such technology could help reduce issues related to the surplus of electricity from renewable energy sources by converting it into heat or cold. To reliably assess the benefits achievable in these emerging applications, it is necessary to develop models which can simulate not only the steady-state operation but also the dynamic response of the system wit…
The effect of the Spanish Law of Political Parties (LPP) on the attitude of the Basque Country population towards ETA: A dynamic modelling approach
2013
Abstract In June 2002, the Spanish Government passed the “Law of Political Parties” (LPP) with the aim, among others, of preventing parties giving political support to terrorist organizations. This law affected the Basque nationalist party “Batasuna”, due to its proved relation with ETA. In this paper, taking data from the Euskobarometro (Basque Country survey) related to the attitude of the Basque population towards ETA, we propose a dynamic model for the pre-LPP scenario. This model will be extrapolated to the future in order to predict what would have happened to the attitude of the Basque population if the law had not been passed. These model predictions will be compared to post-LPP dat…
Water losses dynamic modelling in water distribution networks
2015
In the last decades, one of the main concerns of the water system managers have been the minimisation of water losses, that frequently reach values of 30% or even 70% of the volume supplying the water distribution network. The economic and social costs associated with water losses in modern water supply systems are rapidly rising to unacceptably high levels. Furthermore, the problem of the water losses assumes more and more importance mainly when periods of water scarcity occur or when not sufficient water supply takes part in areas with fast growth. In the present analysis, a dynamic model was used for estimating real and apparent losses of a real case study. A specific nodal demand model …
