Measuring node decentralisation in blockchain peer to peer networks
(Elsevier, 2023-02-08)New blockchain platforms are launching at a high cadence, each fighting for attention, adoption, and infrastructure resources. Several studies have measured the peer-to-peer (P2P) network decentralisation of Bitcoin and ... -
Species mixing proportion and aridity influence in the height–diameter relationship for different species mixtures in Mediterranean forests
(MDPI, 2022-01-14)Estimating tree height is essential for modelling and managing both pure and mixed forest stands. Although height–diameter (H–D) relationships have been traditionally fitted for pure stands, attention must be paid when ... -
A system dynamics approach to increasing ocean literacy
(Frontiers Media, 2019-06-28)Ocean Literacy (OL) has multiple aspects or dimensions: from knowledge about how the oceans work and our impact on them, to attitudes toward topics such as sustainable fisheries, and our behaviour as consumers, tourists, ... -
A system dynamics approach to sustainability education
(Wiley, 2021-01-14)This article describes a randomised controlled trial (RCT) study design to evaluate an innovative online tool to support education for sustainable development (ESD). The learning tool incorporates Systems Thinking and ... -
An empirical study of the impact of systems thinking and simulation on sustainability education
(MDPI, 2021-12-30)Education for sustainable development (ESD) is considered vital to the success of the United Nations¿ sustainable development goals. Systems thinking has been identified as a core competency that must be included in ESD. ... -
Multi-objective multi-agent decision making: a utility-based analysis and survey
(Springer Verlag, 2019-12-09)The majority of multi-agent system implementations aim to optimise agents policies with respect to a single objective, despite the fact that many real-world problem domains are inherently multi-objective in nature. ... -
When and why metaheuristics researchers can ignore “No Free Lunch” theorems
(Springer, 2019-03-25)The No Free Lunch (NFL) theorem for search and optimisation states that averaged across all possible objective functions on a fixed search space, all search algorithms perform equally well. Several refined versions of the ... -
Input and output data analysis for system dynamics modelling using the tidyverse libraries of R
(Wiley, 2018-09-07)From a number of perspectives, system dynamics is a data‐intensive activity. First, each modelling challenge addresses behaviour over time, where historical time series data inform the model‐building process, and techniques ... -
Follow flee: A contingent mobility strategy for the spatial prisoner's dilemma
(Springer Verlag, 2016-08-10)This paper presents results from a series of experimental simulations comparing the performances of mobile strategies of agents participating in the Spatial Prisoner's Dilemma game. The contingent movement strategies Walk ... -
Simulation of an optional strategy in the prisoner’s dilemma in spatial and non-spatial environments
(Springer Verlag, 2016-08-10)This paper presents research comparing the effects of different environments on the outcome of an extended Prisoner's Dilemma, in which agents have the option to abstain from playing the game. We consider three different ... -
A further analysis of the role of heterogeneity in coevolutionary spatial games
(Elsevier, 2017-11-04)Heterogeneity has been studied as one of the most common explanations of the puzzle of cooperation in social dilemmas. A large number of papers have been published discussing the effects of increasing heterogeneity in ... -
System dynamics modelling to support policy analysis for sustainable health care
(2014)System dynamics (SD) is an established simulation methodology used to explore the behaviour of social systems over time. The field has addressed challenging sustainability problems in fisheries, urban planning and environmental ... -
Improving spectral library search by redefining similarity measures
(Journal Of Chemical Information And Modeling, 2015-04-22)Similarity plays a central role in spectral library search. The goal of spectral library search is to identify those spectra in a reference library of known materials that most closely match an unknown query spectrum, on ... -
A groupware system for virtual product innovation management
(Wiley, 2007-10-11)We are experiencing a radical shift in the way organizations are designed, structured, and organized. New organizational forms such as virtual strategic partnerships and networks are replacing traditional bureaucratic, ... -
A Framework for Digital Wide-Area Survey from Aerial Photographs
(Wordwell Ltd., 1998)Despite the potential offered by modern computer technology to the labour-intensive work of 'Aerial Archaeology', few applications have been published. Where developments have been made, they have tended to be carried out ... -
Collaborative Virtual Environments to Support Communication and Community in Internet-Based Distance Education
(jite.org, 2002)In this paper we discuss the use of modern information and communication technologies for distance education (DE) purposes. We argue that current technologies and implementations do not adequately support the key concepts ... -
Digital elevation modelling of individual monuments from aerial photographs
(John Wiley & Sons, 1999)Digital elevation models (DEM) are crucial data products for a variety of geographic applications, and their generation directly from digitized stereopairs of vertical aerial photographs has recently been accomplished. ... -
The influence of random interactions and decision heuristics on norm evolution in social networks
(Springer, 2011-05)In this paper we explore the effect that random social interactions have on the emergence and evolution of social norms in a simulated population of agents. In our model agents observe the behaviour of others and update ... -
Observations on the shortest independent loop set algorithm
(System Dynamics Society / Wiley, 2012-07-31)The shortest independent loop set (SILS) algorithm is a widely adopted loop selection method in eigenvalue elasticity analysis to identify dominant loops. However, we find that, in an individual-based model, the SILS cannot ... -
Co-evolutionary analysis: a policy exploration method for system dynamics models
(System Dynamics Society / Wiley, 2012-10-22)In system dynamics (SD), complex nonlinear systems can generate a wide range of possible behaviours that frequently require search and optimization algorithms in order to explore optimal policies. Within the SD literature, ...
