    • Cross-cultural assessment of automatically generated multimodal referring expressions in a virtual world 

      LUZ, SATURNINO (2012)
      This paper presents an assessment of automatically generated multimodal referring expressions as produced by embodied conversational agents in a virtual world. The algorithm used for this purpose employs general principles ...

    • A Universal Clinical Decision Support System using semantic web services 

      HEDERMAN, LUCY MARY; KHAN, HASEEB AHMAD (2012)
      In this paper we propose the use of semantic web services to achieve a universal clinical decision support system (CDSS). Our goal is to develop a semi-automated approach to discover, select and compose CDSSs available as ...

    • Quality Estimation: an experimental study using unsupervised similarity measures 

      VOGEL, CARL (The Association for Computational Linguistics (ACL), 2012)
      We present the approach we took for our participation to the WMT12 Quality Estimation Shared Task: our main goal is to achieve reasonably good results without appeal to supervised learning. We have used various similarity ...

    • A protected LR-PON deployment for the UK 

      Ruffini, Marco (2011)

    • Skinning with Dual Quaternions 

      Kavan, Ladislav; Collins, Steven; O'Sullivan, Carol; COLLINS, STEVEN (2007)
      Skinning of skeletally deformable models is extensively used for real-time animation of characters, creatures and similar objects. The standard solution, linear blend skinning, has some serious drawbacks that require artist ...

    • Geopostors: A Real-Time Geometry/Impostor Crowd Rendering System: 

      DOBBYN, SIMON; O'SULLIVAN, ANN CAROL; Hamill, David; O'Conor, keith (ACM Press, 2005)
      The simulation of large crowds of humans is important in many fi elds of computer graphics, including real-time applications such as games, as they can breathe life into otherwise static scenes and enhance believability. ...

    • Collisions and Attention 

      O'SULLIVAN, ANN CAROL (2005)
      Attention is an important factor in the perception of static and dynamic scenes, which should, therefore, be taken into account when creating graphical images and animation. Recently, researchers have recognized this fact ...

    • Collisions and attention 

      O'SULLIVAN, ANN CAROL; Lee, Richard (ACM Press, 2004)

    • Sphere-tree construction using dynamic medial axis approximation. 

      BRADSHAW, GARETH; O'SULLIVAN, CAROL (ACM, 2002)
      Collision handling is very computationally expensive, especially in large scale interactive animations. Hierarchical object representations play an important role in performing ef?cient collision handling. Many different ...

    • Smooth Movers: Perceptually Guided Human Motion Simulation 

      MCDONNELL, RACHEL; NEWELL, FIONA; O'SULLIVAN, CAROL (ACM Press, 2007)
      To animate a character, a number of poses are displayed in quick succession in order to create the illusion of motion. For most real-time applications, such as games, the pose update rate is largely constrained by the ...

    • Real-time Collision Detection and Response using Sphere-trees 

      O'SULLIVAN, CAROL; DINGLIANA, JOHN (1999)
      In this paper we address the problem of collision detection and response in real-time animation systems. We describe an approach, which approximates objects using sphere-trees, and uses an interruptible detection algorithm ...

    • Isosurface Extraction on the CELL Processor 

      O'CONOR, KEITH; O'SULLIVAN, CAROL; COLLINS, STEVEN (2006)
      In this paper we describe a parallel method of extracting isosurfaces from large volumetric datasets, adapted for implementation on the Cell Broadband Engine (CBE). The CBE is a new multicore microprocessor architecture ...

    • On Record Keeping at Multidisciplinary Team Meetings 

      KANE, BRIDGET (IEEE, 2011)
      This paper explores issues related to record keeping at multidisciplinary medical team (MDT) meetings. Based on questionnaire and interview data with MDT members of various specialities, roles and teams, the information ...

    • Server Selection for Carbon Emission Control 

      O'MAHONY, DONAL (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 

      BRESCIANI, RICCARDO (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 

      LUZ, SATURNINO (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 

      VOGEL, CARL; LI, BAOLI (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 

      VOGEL, CARL (Springer, 2009)
