  • Ubiquitous interactive art displays: are they wanted, are they intuitive? 

    Burrows, Gary
    The purpose of this study was to create a ubiquitous proximity activated interactive digital display system providing adjusted artworks as content for evaluating viewer reactions and opinions to determine if similar ...
  • UML and the Semantic Web 

    Cranefield, Stephen
    This paper discusses technology to support the use of UML for representing ontologies and domain knowledge in the Semantic Web. Two mappings have been defined and implemented using XSLT to produce Java classes and an RDF ...
  • UML as an ontology modelling language 

    Cranefield, Stephen; Purvis, Martin
    Current tools and techniques for ontology development are based on the traditions of AI knowledge representation research. This research has led to popular formalisms such as KIF and KL-ONE style languages. However, these ...
  • UML-based ontology modelling for software agents 

    Cranefield, Stephen; Haustein, Stefan; Purvis, Martin
    Ontologies play an important role in defining the terminology that agents use in the exchange of knowledge-level messages. As object-oriented modelling, and the Unified Modeling Language (UML) in particular, have built up ...
  • Understanding the Etiology of Electoral Violence: The Case of Zimbabwe 

    Fielding, David
    Recent theoretical and empirical work indicates that incumbent governments are likely to attempt to influence election outcomes by violent means (rather than by bribery and fraud) when their level of popular support is ...
  • Unilateral liberalisation in a multilateral world 

    Richardson, Martin
    Recent years have seen a great deal of trade liberalisation worldwide, particularly via the vehicles of regionalism and bilateralism. Certainly, the focus of analysts and policy economists has been firmly on these means ...
  • The Union Threat Effect in Construction: An Illustration with Data from Plumber and Pipefitter Union Locals 

    Duncan, Kevin; Philips, Peter; Prus, Mark
    Data from plumbing and pipefitting union locals are used to measure the effect of union organizing strength on the wages of high-skilled and semi-skilled nonunion workers. We find that increases in union strength are ...
  • The use of a metadata repository in spatial database development 

    Cockcroft, Sophie
    Database schemas currently used to define spatial databases are deficient in that they do not incorporate facilities to specify business rules/integrity constraints. This shortcoming has been noted by Günther and Lamberts ...
  • Usenet newsgroups’ profile analysis utilising standard and non-standard statistical methods 

    Sallis, Philip; Kassabova, Diana
    The paper explores building profiles of Newsgroups from a corpus of Usenet E-mail messages employing some standard statistical techniques as well as fuzzy clustering methods. A large set of data from a number of Newsgroups ...
  • User defined spatial business rules: storage, management and implementation — a pipe network case study 

    Cockcroft, Sophie
    The application of business rules as a means of ensuring data quality is an accepted approach in information systems development. Rules, defined by the user, are stored and manipulated by a repository or data dictionary. ...
  • Using consensus ensembles to identify suspect data 

    Clark, David
    In a consensus ensemble all members must agree before they classify a data point. But even when they all agree some data is still misclassified. In this paper we look closely at consistently misclassified data to investigate ...
  • Using data models to estimate required effort in creating a spatial information system 

    Benwell, George L; MacDonell, Stephen
    The creation of spatial information systems can be viewed from many directions. One such view is to see the creation in terms of data collection, data modelling, codifying spatial processes, information management, analysis ...
  • Using genetic algorithms for an optical thin-film learning model 

    Li, Xiaodong; Purvis, Martin
    A novel connectionist architecture based on an optical thin-film multilayer model (OTFM) is described. The architecture is explored as an alternative to the widely used neuron-inspired models, with the thin-film thicknesses ...
  • Using rough sets to study expert behaviour in induction of labour 

    Parry, David; Yeap, Wai Kiang; Pattison, Neil
    The rate of induction of labour (IOL) is increasing, despite no obvious increase in the incidence of the major indications. However the rate varies widely between different centres and practitioners and this does not seem ...
  • Using the Internet to teach health informatics 

    Parry, David; Breton, Alice; Abernethy, David; Cockcroft, Sophie; Gillies, John
    Since July 1998 we have been teaching an Internet-based distance learning course in health informatics. The development of this course and the experiences we have had running it are described in this paper. The course was ...
  • Using trust for key distribution and route selection in wireless sensor networks 

    Lewis, Nathan D; Foukia, Noria; Govan, Donovan G
    This paper presents a new approach of dynamic symmetric key distribution for encrypting the communication between two nodes in a Wireless Sensor Network (WSN). The distribution of a shared key can be performed by any sensor ...
  • Vector opinion dynamics: An extended model for consensus in social networks 

    Alaali, Alya; Savarimuthu, Bastin Tony Roy; Purvis, Maryam A.
    Most people hold a variety of opinions on different topics ranging from sports, entertainment, spiritual beliefs to moral principles. These can be based on a personal reflection and evaluation or on their interactions with ...
  • Verifying social expectations by model checking truncated paths 

    Cranefield, Stephen; Winikoff, Michael
    One approach to moderating the behaviour of agents in open societies is the use of explicit languages for defining norms, conditional commitments and/or social expectations, together with infrastructure supporting conformance ...
  • Vietnam: The Next Asian Tiger? 

    Barker, Tom; Ungor, Murat
    We investigate the growth experience of Vietnam, the country which has been getting recent attention as being the next emerging giant. First, we present an aggregate level investigation of Vietnam's economic growth ...
  • View-based consistency and its implementation 

    Huang, Zhiyi; Sun, Chengzheng; Cranefield, Stephen; Purvis, Martin
    This paper proposes a novel View-based Consistency model for Distributed Shared Memory. A view is a set of ordinary data objects that a processor has the right to access in a data-race-free program. The View-based Consistency ...
