Improving spectral library search by redefining similarity measures
(Journal Of Chemical Information And Modeling, 20150422)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 ... 
The influence of random interactions and decision heuristics on norm evolution in social networks
(Springer, 201105)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 ... 
Input and output data analysis for system dynamics modelling using the tidyverse libraries of R
(Wiley, 20180907)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 ... 
An introduction to system dynamics
(Cham: Springer, 20160615)This chapter presents the important concepts underlying the system dynamics modeling method. Following an initial definition of the term model, a summary of a successful system dynamics intervention is described. The key ... 
A learning architecture for scheduling workflow applications in the cloud
(IEEE, 20110915)The scheduling of workflow applications involves the mapping of individual workflow tasks to computational resources, based on a range of functional and nonfunctional quality of service requirements. Workflow applications ... 
A Machine Learning Application for Classification of Chemical Spectra
(2008)This paper presents a software package that allows chemists to analyze spectroscopy data using innovative machine learning (ML) techniques. The package, designed for use in conjunction with labbased spectroscopic ... 
Modeling limits to growth
(Springer, Cham, 20160615)This chapter introduces system dynamics models of limits to growth. First, a onestock model is presented, where the growth rate varies, and is influenced by the system’s carrying capacity. Second, a model of economic ... 
MultiClass and SingleClass Classification Approaches to Vehicle Model Recognition from Images
(2005)This paper investigates the use of machine learning classification techniques applied to the task of recognising the make and model of vehicles. Although a number of vehicle classification systems already exist, most of ... 
Neural Network Approach to Predicting Stock Exchange Movements using External Factors
(2005)The aim of this study is to evaluate the effectiveness of using external indicators, such as commodity prices and currency exchange rates, in predicting movements in the Dow Jones Industrial Average index. The performance ... 
Neutrality through transcription and translation in genetic algorithm representation
(SciTePress Digital Library, 20121005)This paper examines the use of the biological concepts of transcription and translation, to introduce neutrality into the representation of a genetic algorithm (GA). The aim of the paper is to attempt to identify problem ... 
Observations on the shortest independent loop set algorithm
(System Dynamics Society / Wiley, 20120731)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 individualbased model, the SILS cannot ... 
On the Classification Performance of TAN and General Bayesian Networks
(Elsevier, 2009)Over a decade ago, Friedman et al. introduced the Tree Augmented Naïve Bayes (TAN) classifier, with experiments indicating that it significantly outperformed Naïve Bayes (NB) in terms of classification accuracy, ...

OneClass Support Vector Machine Calibration Using Particle Swarm Optimisation
(2007)Abstract. Populationbased search methods such as evolutionary algorithms, shuffled complex algorithms, simulated annealing and ant colony search are increasingly used as automatic calibration methods ... 
The optional prisoner's dilemma in a spatial environment: Coevolving game strategy and link weights
(SciTePress Digital Library, 2016)In this paper, the Optional Prisoner’s Dilemma game in a spatial environment, with coevolutionary rules for both the strategy and network links between agents, is studied. Using a Monte Carlo simulation approach, a number ... 
Organizational context and the IS implementation process: an integrated research framework
(2000)Good IS managers have an intuitive grasp of the complex organizational and project dynamics required for successful implementation of large information systems. Years of hardearned experience have taught them that IS ... 
Particle swarm optimisation with gradually increasing directed neighbourhoods
(Association for Computing Machiner, 2011)Particle swarm optimisation (PSO) is an intelligent random search algorithm, and the key to success is to effectively balance between the exploration of the solution space in the early stages and the exploitation of the ... 
PlayerTraced Empirical CostSurfaces for A* Pathfinding
(Eurosis, 2011)This paper discusses the use of empirical costsurfaces derived from substantial amounts of playertraced movements in an online vehicular combat game, for the purposes of improving A* pathfinding by AI vehicles. The ... 
Polarity assessment of thermoresponsive poly(NIPAMcoNtBA) copolymer films using fluorescence methods.
(Springer, 2010)The insitu, noncontact, and nondestructive measurement of the physicochemical properties such as the polarity of thin, hydrophilic polymer films is desirable in many areas of polymer science. Polarity is a complex factor ...
