Journal Article
Qu, R., Xu, Y., Castro-Gutierrez, J., & Landa-Silva, D. (2013). Particle swarm optimization for the Steiner tree in graph and delay-constrained multicast routing problems. Journal of Heuristics, 19(2), https://doi.org/10.1007/s10732-012-9198-2

This paper presents the first investigation on applying a particle swarm optimization (PSO) algorithm to both the Steiner tree problem and the delay constrained multicast routing problem. Steiner tree problems, being the underlining models of many ap... Read More about Particle swarm optimization for the Steiner tree in graph and delay-constrained multicast routing problems.

Recovering complete plant root system architectures from soil via X-ray μ-computed tomography (2013)
Journal Article
Mairhofer, S., Zappala, S., Tracy, S., Sturrock, C., Bennett, M. J., Mooney, S. J., & Pridmore, T. (2013). Recovering complete plant root system architectures from soil via X-ray μ-computed tomography. Plant Methods, 9, Article 8. https://doi.org/10.1186/1746-4811-9-8

Background: X-ray micro-Computed Tomography (μCT) offers the ability to visualise the three-dimensional
structure of plant roots growing in their natural environment – soil. Recovery of root architecture descriptions from X-ray CT data is, however,... Read More about Recovering complete plant root system architectures from soil via X-ray μ-computed tomography.

Euler principal component analysis (2013)
Journal Article
Liwicki, S., Tzimiropoulos, G., Zafeiriou, S., & Pantic, M. (2013). Euler principal component analysis. International Journal of Computer Vision, 101(3), https://doi.org/10.1007/s11263-012-0558-z

Principal Component Analysis (PCA) is perhaps the most prominent learning tool for dimensionality reduction in pattern recognition and computer vision. However, the ℓ 2-norm employed by standard PCA is not robust to outliers. In this paper, we propos... Read More about Euler principal component analysis.

Theoretical formulation and analysis of the deterministic dendritic cell algorithm (2013)
Journal Article
Gu, F., Greensmith, J., & Aickelin, U. (2013). Theoretical formulation and analysis of the deterministic dendritic cell algorithm. BioSystems, 111(2), 127-135. https://doi.org/10.1016/j.biosystems.2013.01.001

As one of the emerging algorithms in the field of artificial immune systems (AIS), the dendritic cell algorithm (DCA) has been successfully applied to a number of challenging real-world problems. However, one criticism is the lack of a formal definit... Read More about Theoretical formulation and analysis of the deterministic dendritic cell algorithm.

Individual differences in behavioural inhibition explain free riding in public good games when punishment is expected but not implemented (2013)
Journal Article
Skatova, A., & Ferguson, E. (2013). Individual differences in behavioural inhibition explain free riding in public good games when punishment is expected but not implemented. Behavioral and Brain Functions, 9(3), https://doi.org/10.1186/1744-9081-9-3

Background: The literature on social dilemmas and punishment focuses on the behaviour of the punisher. However, to fully explain the effect of punishment on cooperation, it is important to understand the psychological mechanisms influencing the behav...

Optimization problems for fast AAM fitting in-the-wild (2013)
Presentation / Conference Contribution
Tzimiropoulos, G., & Pantic, M. Optimization problems for fast AAM fitting in-the-wild. Presented at 2013 IEEE International Conference on Computer Vision (ICCV)

We describe a very simple framework for deriving the most-well known optimization problems in Active Appearance Models (AAMs), and most importantly for providing efficient solutions. Our formulation results in two optimization problems for fast and e... Read More about Optimization problems for fast AAM fitting in-the-wild.

Overview of telematics-based prognostics and health management systems for commercial vehicles (2013)
Journal Article

Prognostics and Health Management/Monitoring (PHM) are methods to assess the health condition and reliability of systems for the purpose of maximising operational reliability and safety. Recently, PHM systems are emerging in the automotive industry.... Read More about Overview of telematics-based prognostics and health management systems for commercial vehicles.

A time predefined variable depth search for nurse rostering (2013)
Journal Article
Burke, E., Curtois, T., Qu, R., & Vanden Berghe, G. (2013). A time predefined variable depth search for nurse rostering. INFORMS Journal on Computing, 25(3), https://doi.org/10.1287/ijoc.1120.0510

This paper presents a variable depth search for the nurse rostering problem. The algorithm works by chaining together single neighbourhood swaps into more effective compound moves. It achieves this by using heuristics to decide whether to continue ex... Read More about A time predefined variable depth search for nurse rostering.

Domain transformation approach to deterministic optimization of examination timetables (2013)
Journal Article
Abdul Rahim, S., Bargiela, A., & Qu, R. (2013). Domain transformation approach to deterministic optimization of examination timetables. Artificial Intelligence Research, 2(1), https://doi.org/10.5430/air.v2n1p122

In this paper we introduce a new optimization method for the examinations scheduling problem. Rather than attempting direct optimization of assignments of exams to specific time-slots, we perform permutations of slots and reassignments of exams upon...

Tension space analysis: Exploring community requirements for networked urban screens (2013)
Presentation / Conference Contribution
North, S., Schnädelbach, H., Fatah gen Schieck, A., Motta, W., Ye, L., Behrens, M., & Kostopoulou, E. (2013, September). Tension space analysis: Exploring community requirements for networked urban screens. Presented at 14th IFIP TC 13 International Conference, Cape Town, South Africa

This paper draws on the design process, implementation and early evaluation results of an urban screens network to highlight the tensions that emerge at the boundary between the technical and social aspects of design. While public interactive screens... Read More about Tension space analysis: Exploring community requirements for networked urban screens.
