We present an electronic book titled " Simulation and Modelling of System Dynamics" , just recently published online by the International Environmental Modelling & Software Society (iEMSs), and authored by the late Peter Benyon.Simulation allows exploration of more complex models than can be analysed theoretically; it can be used where trials on the real world system would be too costly, time consuming or dangerous. This book provides for the needs of those undertaking simulation.The book aims at a wide readership using an informal style. The material varies from elementary to advanced and encourages selective browsing and reading, with a wide range of examples and chapter summaries to aid this choice.The material focuses on the need to formulate the models with the right structure and equations - in other words, it concentrates on system description rather than model solution. The importance of subsequent validation is indicated.The book is freely accessible and it is available online as a PDF file at: http://www.iemss.org/docs/books/ModSimSysDynA.pdf. © 2011 Elsevier Ltd.

SmartH2O is an EU funded project which aims at creating a virtuous feedback cycle between water users and the utilities, providing users information on their consumption in quasi real time, and thus enabling water utilities to plan and implement strategies to reduce/reallocate water consumption. Traditional metering data, usually gathered twice a year, can be used to model consumers' behaviour at an aggregate level, but the motivations and individual attitudes of consumers are hidden. The advent of smart water meters allows gathering high frequency consumption data that can be used to provide instantaneous information to water utilities on the state of the network. At the same time, the consumption information can be fed back to the user to stimulate increased awareness on water use. The SmartH2O project aims at developing methodologies to involve consumers and promote water savings by increasing their awareness, using a social computing approach, and also exploring their sensitivity to water prices, e.g., to penalise water waste during droughts. In this paper, first we review similar experiences that exploit consumer awareness to reduce consumption, then we review the role of persuasive games for sustainability, and finally we present the SmartH2O approach, sketching the architecture of its modelling and social computing components.

We show that Incremental Slow Feature Analysis (IncSFA) provides a low complexity method for learning Proto-Value Functions (PVFs). It has been shown that a small number of PVFs provide a good basis set for linear approximation of value functions in reinforcement environments. Our method learns PVFs from a high-dimensional sensory input stream, as the agent explores its world, without building a transition model, adjacency matrix, or covariance matrix. A temporal-difference based reinforcement learner improves a value function approximation upon the features, and the agent uses the value function to achieve rewards successfully. The algorithm is local in space and time, furthering the biological plausibility and applicability of PVFs. © 2012 Springer-Verlag. Source

We present a novel framework for learning morphological operators using counter-harmonic mean. It combines concepts from morphology and convolutional neural networks. A thorough experimental validation analyzes basic morphological operators dilation and erosion, opening and closing, as well as the much more complex top-hat transform, for which we report a real-world application from the steel industry. Using online learning and stochastic gradient descent, our system learns both the structuring element and the composition of operators. It scales well to large datasets and online settings. © 2013 Springer-Verlag. Source

The SmartH2O project aims to provide water utilities, municipalities and citizens with an ICT enabled platform to design, develop and implement better water management policies using innovative metering, social media and pricing mechanisms. This project has as a working hypothesis that high data quality obtained from smart meters and communicable through social media and other forms of interaction could be used to design and implement innovative and effective water pricing policies. Planned case studies in the UK and Switzerland are introduced. We anticipate that SmartH20 research outcomes will be of use to those interested in linking smart metering, social media and smart pricing approaches to achieve more sustainable water management outcomes. © 2014 The Authors.
