Book Chapter
Kabir, S., Walker, M., & Papadopoulos, Y. (2014). Reliability analysis of dynamic systems by translating temporal fault trees into Bayesian networks. In Model-Based Safety and Assessment; Lecture Notes in Computer Science (96-109). Springer Verlag. https://doi.org/10.1007/978-3-319-12214-4_8

Classical combinatorial fault trees can be used to assess combinations of failures but are unable to capture sequences of faults, which are important in complex dynamic systems. A number of proposed techniques extend fault tree analysis for dynamic s... Read More about Reliability analysis of dynamic systems by translating temporal fault trees into Bayesian networks.

Partitioning networks into cliques: a randomized heuristic approach (2014)
Journal Article
Chalupa, D. (2014). Partitioning networks into cliques: a randomized heuristic approach. Information Sciences and Technologies Bulletin of the ACM Slovakia, 6(3), 1-8

In the context of community detection in social networks, the term community can be grounded in the strict way that simply everybody should know each other within the community. We consider the corresponding community detection problem. We search for... Read More about Partitioning networks into cliques: a randomized heuristic approach.

A safety analysis approach to clinical workflows : application and evaluation (2014)
Journal Article
Gordon, N., Kabir, S., Sharvia, S., Walker, M., & Al-Qora’n, L. (in press). A safety analysis approach to clinical workflows : application and evaluation. International Journal of Advanced Computer Science and Applications, 4(3), 82-91. https://doi.org/10.14569/SpecialIssue.2014.040310

Clinical workflows are safety critical workflows as they have the potential to cause harm or death to patients. Their safety needs to be considered as early as possible in the development process. Effective safety analysis methods are required to ens... Read More about A safety analysis approach to clinical workflows : application and evaluation.

A target guided subband filter for acoustic event detection in noisy environments using wavelet packets (2014)
Journal Article
Feng, Z.-R., Zhou, Q., Zhang, J., Jiang, P., & Yang, X.-W. (2015). A target guided subband filter for acoustic event detection in noisy environments using wavelet packets. IEEE/ACM transactions on audio, speech, and language processing, 23(2), 361-372. https://doi.org/10.1109/taslp.2014.2381871

This paper deals with acoustic event detection (AED), such as screams, gunshots, and explosions, in noisy environments. The main aim is to improve the detection performance under adverse conditions with a very low signal-to-noise ratio (SNR). A novel...

3D vasculature segmentation using localized hybrid level-set method (2014)
Journal Article
Hong, Q., Li, Q., Wang, B., Li, Y., Yao, J., Liu, K., & Wu, Q. (2014). 3D vasculature segmentation using localized hybrid level-set method. BioMedical Engineering OnLine, 13(1), 169. https://doi.org/10.1186/1475-925X-13-169

Background: Intensity inhomogeneity occurs in many medical images, especially in vessel images. Overcoming the difficulty due to image inhomogeneity is crucial for the segmentation of vessel image. Methods: This paper proposes a localized hybrid leve... Read More about 3D vasculature segmentation using localized hybrid level-set method.

Remembering faces with emotional expressions (2014)
Journal Article

It is known that happy faces create more robust identity recognition memory than faces with some other expressions. However, this advantage was not verified against all basic expressions. Moreover, no research has assessed whether similar differences... Read More about Remembering faces with emotional expressions.
