Server Selection for Carbon Emission Control
(2011)Cloud owners are allowing their users to specify the level of resources being used in the di erent geographical locations that make up the cloud. The carbon emissions caused by powering these resources can vary greatly ... -
The ZRTP Protocol - Analysis on the Diffie-Hellman mode
(2009)ZRTP is a key agreement protocol by Philip Zimmermann, Alan Johnston and Jon Callas, which relies on a Di e-Hellman exchange to generate SRTP session parameters, providing con dentiality and protecting against Man-in-the-Middle ... -
Comparing static Gantt and mosaic charts for visualization of task schedules
(IEEE, 2011)A mosaic chart has been proposed for representation of events on a timeline. While early studies demonstrated the effectiveness of mosaics in supporting visualization of multimedia records on a meeting browser, the usability ... -
Improving Multiclass Text Classification with Error-Correcting Output Coding and Sub-class Partitions
(Springer, 2010)Error-Correcting Output Coding (ECOC) is a general framework for multiclass text classification with a set of binary classifiers. It can not only help a binary classifier solve multi-class classification problems, but also ... -
Emoticonsciousness
(Springer, 2009)A temporal analysis of emoticon use in Swedish, Italian, German and English asynchronous electronic communication is reported. Emoticons are classified as positive, negative or neutral. Postings to newsgroups over a 66 ... -
Model-driven engineering of planning and optimisation algorithms for pervasive computing environments
(2011)This paper presents a model-driven approach to developing pervasive computing applications that exploits design-time information to support the engineering of planning and optimisation algorithms that reflect the presence ... -
Optimizing interpreters by tuning opcode orderings on virtual machines for modern architectures
(ACM, 2011)Virtual machines (VMs) are commonly used to implement programming languages such as Java, Python and Lua. VMs are typically implemented using an interpreter, a JIT compiler, or some combination of the two. A long-standing ... -
Track validation using gradient-based normalised cross-correlation
(BMVA Press, 2011)We develop a gradient-based normalised cross-correlation tracker that is as robust as brute-force template matching while being signi?cantly more computationally ef?cient. The technique serves as the basis of our track ... -
Deployment Strategies for Protected Long-Reach PON
(2012)The mass deployment of ?bre access networks is probably the most important network upgrade strategy for operators over the coming decade. Next generation networks, and in particular the Long-Reach Passive Optical Network ... -
A Combinatorial Optimisation Approach to the Design of Dual Parented Long-Reach Passive Optical Networks
(2011)We present an application focused on the design of resilient long-reach passive optical networks. We speci?cally consider dual parented networks whereby each customer must be connected to two metro sites via a local exchange ... -
A Process Algebraic Description of a Temporal Wireless Network Protocol
(2011)The problem of coordination is central to research in robotics, automatically guided vehicles, autonomous cars, unmanned aerial vehicles, and any other areas in which autonomous agents of any kind operate concurrently. ... -
On stochastic tree distances and their training via Expectation-Maximisation
(2012)Continuing a line of work initiated in (Boyer et al., 2007), a generalisation of stochastic string distance to a stochastic tree distance is considered. Hitheto overlooked modifications to the Zhang/Shasha tree-distance ... -
On order equivalences between distance and similarity measures on sequences and trees
(2012)Both ?distance? and ?similarity? measures have been proposed for the comparison of sequences and for the comparison of trees, based on scoring mappings, and the paper concerns the equivalence or otherwise of these. These ... -
Collaboration and multimedia: identifying equilibrium in the MDT information ecosystem
(ACM, 2012)his study of collaboration among a multidisciplinary team of healthcare workers demonstrates that elements intrinsic to the interaction constitute a delicate ecosystem. As the balance between actors, digital media and paper ... -
Towards Multilingual User Models for Personalized Multilingual Information Retrieval
(ACM, 2011-06-09)The majority of studies in Personalized Information Retrieval (PIR) literature have focused on monolingual IR, and only relatively little work has been done concerning multilingual IR. In this paper we propose a novel ... -
Improving Query and Result List Adaptation in Personalized Multilingual Information Retrieval
(ACM, 2011-07)This research study aims to improve personalization in MIR systems, by improving the relevance of multilingual search results with respect to the user and not just the query. The study investigates how to model different ... -
A comparative survey of Personalised Information Retrieval and Adaptive Hypermedia techniques
(Elsevier, 2012-07)A key driver for next generation web information retrieval systems is becoming the degree to which a user?s search and presentation experience is adapted to individual user properties and contexts of use. Over the past ... -
Language and friendships: A co-evolution model of social and linguistic conventions
(World Scientific, 2012)Human social networks are dynamic, yet the majority of computational models of language evolution operate with either fixed or random interaction patterns between agents. This paper presents a model of lexicon formation ...
