A cognitive robot may face failures during the execution of its actions. These failures are mostly due to the gap between the physical world and the constructed symbolic plans, some internal problems that may occur in its embodiment or unexpected external events. In this paper, we propose a visual scene interpretation system for extracting spatial relations among objects in a scene and using th...

Requirements Engineering (RE) is an inherently social process, involving the contribution of individuals working in an organizational context. Furthermore, failures in the RE process will potentially lead to systematic failures in the products that are produced as a result. Consequently, the RE process for dependable systems development should itself be considered as a dependable process, and t...

Recent research suggests that not only does the use of recreational drugs impact on working memory functioning, but more ;everyday' aspects of memory (e.g. remembering to do something in the future) are also affected. Forty-three ecstasy-polydrug users and 51 non-ecstasy users were recruited from a university population. Each participant completed the Cognitive Failures Questionnaire (CFQ) and ...

Experiment 1 demonstrated that intra-individual variability (IIV) on attention contro...

Recent findings in the domain of combining classifiers provide a surprising revision of the usefulness of diversity for modelling combined performance. Although there is a common agreement that a successful fusion system should be composed of accurate and diverse classifiers, experimental results show very weak correlations between various diversity measures and combining methods. Effectively n...
