In this paper we describe the tool we have developed to visualise experimental data on top of the multi-agent simulation platform Presage2 and how we have used it with our Social Capital Framework. The visualisation demonstrates how social capital can be used to self-organise solutions to collective actions problems.
Modularity is a widely used measure for evaluating community structure in networks. The definition of modularity involves a comparison between the observed network and a null model, which serves as a reference. To make the comparison significant, this null model should characterize some features of the observed network. However, the previously used null models are not good representations of real-world...
Many real-world networks exhibit overlapping community structure in which vertices may belong to more than one community. It has been recently shown that community structure plays an import role in epidemic spreading. However, the effect of different vertices on epidemic behavior was still unclear. In this paper, we classify vertices into overlapping and non-overlapping ones, and investigate in detail...
This workshop will bring together researchers interested in raising the efficiency and the effectiveness of Software Product Line Engineering by applying innovative analysis approaches and formal methods.
The purpose of trust and reputation systems is to strengthen the quality of markets and communities by providing an incentive for good behaviour and quality services, and by sanctioning bad behaviour and low quality services. However, trust and reputation systems will only be able to produce this effect when they are sufficiently robust against strategic manipulation or direct attacks. Currently,...
Community acceptance of the object storage device model as represented by standards and use in existing HPC filesystems has enabled the development of more complex data storage systems. Object replicas may be placed in a variety of ways to obtain various properties, such as scalable lookup times, concurrent access to multiple objects, and efficient reorganization. The construction of a fully functional...
We explore the potentials of ldquoopen-source-style-educationrdquo from the viewpoint of an axiomatic approach of cyberworlds adopting an approach to study a basic 4 step reasoning; axiom, theorem, implementation and proof. The first step is defining the axioms of world; ldquoin the evolutionary power, borrowing and utilizing functions exceed owned functions.rdquo The second step is ldquotheoremrdquo...
The automation of software product line (SPL) analyses is of growing interest to both practitioners and researchers. In particular, automated analyses of variability models (like feature or decision models) and languages that foster declarative specifications of programs using those models are now common. We note that many of the problems that SPL engineers face are related to configuration problems...
