Cultural artefacts in education: Analysis, ontologies and implementation (2008)
Presentation / Conference Contribution

Adaptive web technologies are often used in distance learning scenarios with little regard for learners’ cultural background. The CAE questionnaire determines the cultural artefacts that influence a learners behaviour within an educational environmen...

On eliminating packet droppers in MANET: A modular solution (2008)
Journal Article

In this paper we deal with misbehaving nodes in mobile ad hoc networks (MANETs) that drop packets supposed to be relayed, whose purpose may be either saving their resources or launching a DoS attack. We propose a new solution to monitor, detect, and... Read More about On eliminating packet droppers in MANET: A modular solution.

Phase clustering in globally coupled photochemical oscillators (2008)
Journal Article

We experimentally investigate the formation of clusters in a population of globally coupled photochemical oscillators. The system consists of catalytic micro-particles in Belousov-Zhabotinsky solution and the coupling exploits the excitatory properti...

Genetic algorithms with dynamic mutation rates and their industrial applications (2008)
Journal Article

This paper presents a method on how to estimate main effects of gene representation. This estimate can be used not only to understand the domination of genes in the representation but also to design the mutation rate in genetic algorithms (GAs). A ne...

Ontology assisted query reformulation using the semantic and assertion capabilities of OWL-DL ontologies (2008)
Presentation / Conference Contribution

End users of recent biomedical information systems are often unaware of the storage structure and access mechanisms of the underlying data sources and can require simplified mechanisms for writing domain specific complex queries. This research aims t... Read More about Ontology assisted query reformulation using the semantic and assertion capabilities of OWL-DL ontologies.

A particle swarm optimization algorithm for multiuser scheduling in HSDPA (2008)
Presentation / Conference Contribution

This paper briefs the problem of optimal multiuser scheduling in HSDPA. The modulation and coding schemes (MCSs), numbers of multicodes and power levels for all users are jointly optimized at each scheduling period, given that only limited Channel Qu...

Dynamic control and information processing in the Belousov-Zhabotinsky reaction using a coevolutionary algorithm (2008)
Journal Article

We propose that the behavior of nonlinear media can be controlled dynamically through coevolutionary systems. In this study, a light-sensitive subexcitable Belousov-Zhabotinsky reaction is controlled using a heterogeneous cellular automaton. A checke...

The BPMSOA: evaluating the enactment of a business process using application domain specific grid services (2008)
Presentation / Conference Contribution

Verifying resource requirements for distributed rule-based systems (2008)
Presentation / Conference Contribution

Rule-based systems are rapidly becoming an important component of ‘mainstream’ computing technologies, for example in business process modelling, the semantic web, sensor networks etc. However, while rules provide a flexible way of implementing such...

Semantic matching for the medical domain (2008)
Presentation / Conference Contribution

This paper proposes some modifications to the SMatch algorithm that enables the semantic matching of medical terminologies using the Unified Medical Language System (UMLS) as a source of background knowledge. Semantic Matching is the process of disco... Read More about Semantic matching for the medical domain.

Multiuser scheduling in HSDPA using simulated annealing (2008)
Presentation / Conference Contribution

In this paper, the issue of multiuser scheduling in the context of the High Speed Downlink Packet Access (HSDPA) is addressed. Given limited radio resources at the base station, the main challenge is to assign these resources to multiple users at eac...

Semantic visualization of patient information (2008)
Presentation / Conference Contribution

Clinical practice and research rely increasingly on analytic approaches to patient data. Visualization enables the comparative exploration of similar patients, a key requirement in certain clinical decision support systems. Patient data is complex an...

Sequential and parallel variable neighborhood search algorithms for job shop scheduling (2008)
Book Chapter

Variable Neighborhood Search (VNS) is a recently invented metaheuristic to use in solving combinatorial optimization problems in which a systematic change of neighborhood with a local search is carried out. However, as happens with other meta-heurist... Read More about Sequential and parallel variable neighborhood search algorithms for job shop scheduling.

Ontology-driven requirements engineering: building the ontoREM meta model (2008)
Presentation / Conference Contribution

The present paper gives an insight into the process of developing the metamodel of OntoREM, an Ontology-driven Requirements Engineering Methodology, which is currently being developed at the University of the West of England in close cooperation with...

Using assertion capabilities of an OWL-based ontology for query formulation (2008)
Presentation / Conference Contribution

This paper reports on the development of a framework to assist users in formulating relational queries without requiring a complete knowledge of the information structure and access mechanisms to underlying data sources. The emphasis here is on explo... Read More about Using assertion capabilities of an OWL-based ontology for query formulation.
