Worker/wrapper/makes it/faster (2014)
Conference Proceeding

Much research in program optimization has focused on formal approaches to correctness: proving that the meaning of programs is preserved by the optimisation. Paradoxically, there has been comparatively little work on formal approaches to efficiency:... Read More about Worker/wrapper/makes it/faster.

Musical intersections across the digital and physical (2014)
Conference Proceeding

Digital musical experiences are commonplace, everyday occurrences for many of us. Digital technologies facilitate where, how and what we access, and they increasingly offer new methods for capturing, sharing, enhancing and supporting such musical exp...

Circular polarization in n-type resonant tunneling diodes with Si delta-doping in the quantum well (2014)
Conference Proceeding

In this work, we have investigated magneto-transport and polarization resolved photoluminescence of a GaAs/AlGaAs resonant tunneling diode with Si delta-doping at the center of the quantum well under a magnetic field parallel to the tunnel current. T... Read More about Circular polarization in n-type resonant tunneling diodes with Si delta-doping in the quantum well.

The use of alternative double number lines as models of ratio tasks and as models for ratio relations and scaling (2014)
Conference Proceeding

In this paper we draw on ICCAMS project materials that used the double number line (DNL) to develop secondary school students’ understanding of multiplicative reasoning. In particular, we look at the use of a DNL, and its alternative version, as a mo...

A data mining framework to model consumer indebtedness with psychological factors (2014)
Conference Proceeding

Modelling Consumer Indebtedness has proven to be a problem of complex nature. In this work we utilise Data Mining techniques and methods to explore the multifaceted aspect of Consumer Indebtedness by examining the contribution of Psychological Factor...

Saturable and dispersive parity-time symmetric directional coupler: a transmission-line modelling study (2014)
Conference Proceeding

In this paper, numerical modelling of Parity-Time (PT) coupled waveguides is reported. The PT coupled waveguide structure consists of two coupled slab waveguides based on GaAs material with gain/loss material parameter models, including both dispersi...

Modelling of dispersive PT-symmetric Bragg grating (2014)
Conference Proceeding

This paper reports on the time-domain numerical model of a parity-time Bragg grating with saturated and dispersive gain. The model is compared against the ideal PT scenario where the gain is constant and unsaturated for all frequencies.

An evolutionary algorithm for graph planarisation by vertex deletion (2014)
Conference Proceeding

A non-planar graph can only be planarised if it is structurally modified. This work presents a new heuristic algorithm that uses vertices deletion to modify a non-planar graph in order to obtain a planar subgraph. The proposed algorithm aims to delet...

Personalising mobile advertising based on users’ installed apps (2014)
Conference Proceeding

Mobile advertising is a billion pound industry that is rapidly expanding. The success of an advert is measured based on how users interact with it. In this paper we investigate whether the application of unsupervised learning and association rule min... Read More about Personalising mobile advertising based on users’ installed apps.

Incorporating spontaneous reporting system data to aid causal inference in longitudinal healthcare data (2014)
Conference Proceeding

Inferring causality using longitudinal observational databases is challenging due to the passive way the data are collected. The majority of associations found within longitudinal observational data are often non-causal and occur due to confounding....

Refining adverse drug reactions using association rule mining for electronic healthcare data (2014)
Conference Proceeding

Side effects of prescribed medications are a common occurrence. Electronic healthcare databases present the opportunity to identify new side effects efficiently but currently the methods are limited due to confounding (i.e. when an association betwee...

Teacher knowledge for modelling and problem solving (2014)
Conference Proceeding

This article reports on a study that has researched teacher professional learning in lesson study communities that enquired into how we might better support students develop skills in problem solving and mathematical modelling. A rationale for profes... Read More about Teacher knowledge for modelling and problem solving.
