We complete the Wilf classification of signed patterns of length 5 for both signed permutations and signed involutions. New general equivalences of patterns are given which prove Jaggard’s conjectures concerning involutions in the symmetric group avoiding certain patterns of length 5 and 6. In this way, we also complete the Wilf classification of S5, S6, and S7 for involutions.

The ability to match pitches quickly and accurately is essential for proficient singing. We describe a new technique for estimating the time to reach a target frequency that uses adaptive optimal-kernel (AOK) time-frequency representations, designed to optimize the time-frequency tradeoff at each time point. We show in two experiments that this measure is more sensitive to tonal priming effects...

Knowledge representation, defined as the way individuals structure their knowledge and cognitive processing of events and the associated sense-making processes, is believed to influence teachers’ reasoning/thinking skills. While extensively researched in mainstream teacher education, this line of inquiry is essentially lacking in the L2 teacher education literature. To fill some of the void, th...

We define ShapeShifting programmes as interactive and reconfigurable moving image productions that adapt their content, on the fly, to suit the preferences of the viewers or engagers. They are automatically edited at the time of delivery. We have developed a paradigm, a computational model and an accompanying software system for the creation and delivery of ShapeShifting Screen Media programmes...

these are notes from introductory survey lectures given at the institute for studies in theoretical physics and mathematics (ipm), teheran, in 2008 and 2010. we present the definition and the fundamental properties of fomin-zelevinsky’s cluster algebras. then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generators of ...

This contribution describes robust methods to provide a freeviewpoint video visualisation of sport scenes using a multicamera set-up. This allows generation of novel views of actions from any angle and is of interest for visualisation in TV productions. The system utilises 3D reconstruction techniques previously developed for studio use. This paper discusses some experiences found while applyin...

It has previously been shown that inconsistency in the early morpheme productions of typically developing (TD) children and those with Specific Language Impairment (SLI) can be partly explained by the phonological complexity of the coda. However, it is not yet known whether TD and SLI children have similar underlying processes of morpheme acquisition. Of particular interest is the reported late...
