Presentation / Conference Contribution

Open Science is an approach to the conduct of science in which the whole of an ongoing scientific investigation – data, ideas, questions, plans, results and more – is made available online. Open Science began as a way to facilitate the workings of mu... Read More about Muddying the waters or clearing the stream? Open Science as a communication medium.

Groth-Sahai proofs revisited (2010)
Presentation / Conference Contribution

Since their introduction in 2008, the non-interactive zero-knowledge (NIZK) and non-interactive witness indistinguishable (NIWI) proofs designed by Groth and Sahai have been used in numerous applications. In this paper, we offer two contributions to... Read More about Groth-Sahai proofs revisited.

A fault tolerant, dynamic and low latency BDII architecture for grids (2010)
Journal Article

The current BDII model relies on information gathering from agents that run on each core node of a Grid. This information is then published into a Grid wide information resource known as Top BDII. The Top level BDIIs are updated typically in cycles o... Read More about A fault tolerant, dynamic and low latency BDII architecture for grids.

Artificial symbiogenesis and differing reproduction rates (2010)
Journal Article

Symbiosis is the phenomenon in which organisms of different species live together in close association. Symbiogenesis is the name given to the process by which symbiotic partners combine and unify. This letter reconsiders previous work using the NKCS... Read More about Artificial symbiogenesis and differing reproduction rates.

Use of a connection-selection scheme in neural XCSF (2010)
Presentation / Conference Contribution

XCSF is a modern form of Learning Classifier System (LCS) that has proven successful in a number of problem domains. In this paper we exploit the modular nature of XCSF to include a number of extensions, namely a neural classifier representation, sel...

Identifying trade entry and exit timing using mathematical technical indicators in XCS (2010)
Presentation / Conference Contribution

This paper extends current LCS research into financial time series forecasting by analysing the performance of agents utilising mathematical technical indicators for both environment classification and in selecting actions to be executed. It compares... Read More about Identifying trade entry and exit timing using mathematical technical indicators in XCS.

A spiking neural representation for XCSF (2010)
Presentation / Conference Contribution

This paper presents a Learning Classifier System (LCS) where each traditional rule is represented by a spiking neural network, a type of network with dynamic internal state. The evolutionary design process exploits parameter self-adaptation and a con... Read More about A spiking neural representation for XCSF.

Swarms of metaheuristic agents: A model for collective intelligence (2010)
Presentation / Conference Contribution

Swarm intelligence algorithms are created to build collective intelligence based on inherent properties of populations. However, this sort of problem solving approaches use collective evolution of solutions, which make up the population relied on. Th...

Imitation programming (2010)
Presentation / Conference Contribution

Many nature-inspired mechanisms have been presented for computational design and optimization. This paper introduces a population-based approach inspired by a form of cultural learning - imitation. Imitation is typically defined as learning through t... Read More about Imitation programming.

A Malawian school library: Culture, literacy and reader development (2010)
Journal Article

Purpose: This paper aims to investigate the success and suitability of a Western-donated school library in furthering the aims of literacy and reader development in Malawi. Design/methodology/approach: A qualitative, case study approach was taken usi... Read More about A Malawian school library: Culture, literacy and reader development.

Traffic-differentiation-based modular QoS localized routing for wireless sensor networks (2010)
Journal Article

A new localized quality of service (QoS) routing protocol for wireless sensor networks (WSN) is proposed in this paper. The proposed protocol targets WSN's applications having different types of data traffic. It is based on differentiating QoS requir...

Care pathway records and variance data: enabling research through the use of ontologies (2010)
Presentation / Conference Contribution

Integrated care pathways (ICPs), a fine-grained form of medical guideline including the explicit recording of any deviation, or ‘variance’, could serve as a rich source of data for research. Not only do they incorporate a wealth of operational knowle... Read More about Care pathway records and variance data: enabling research through the use of ontologies.

Dynamic parameter control of interactive local search in UML software design (2010)
Presentation / Conference Contribution

User-centered Interactive Evolutionary Computation (IEC) has been applied to a wide variety of areas, including UML software design. The performance of evolutionary search is important as user interaction fatigue remains an on-going challenge in IEC....

A gradual solution to detect selfish nodes in mobile ad hoc networks (2010)
Journal Article

The resource limitation of nodes forming ad hoc networks along with the multi-hop nature of these networks rise a new problem. To preserve its energy a node may behave selfishly and would not forward packets for others, while using their services and...

Aspect oriented software fault tolerance and analytically redundant design framework (2010)
Presentation / Conference Contribution

Diversity or redundancy based software fault tolerance does not come for free; rather it introduces additional complexity to the core functionality in the form of redundancy development, management and controlled execution. This results in tangling o... Read More about Aspect oriented software fault tolerance and analytically redundant design framework.

Self-adaptation of mutation operator and probability for permutation representations in genetic algorithms (2010)
Journal Article

The choice of mutation rate is a vital factor in the success of any genetic algorithm (GA), and for permutation representations this is compounded by the availability of several alternative mutation operators. It is now well understood that there is... Read More about Self-adaptation of mutation operator and probability for permutation representations in genetic algorithms.
