  • 120 years of structural fire testing: Moving away from the status quo 

    Maluk, Cristian; Bisby, Luke (Universitat Politecnica de Valencia (UPV), 2012-10-25)
    During the late 19th Century, stakeholders from the building construction industry were in need of rational, quantified, and repeatable assessment of building materials and structures subject to heating during fire; thus ...
  • The 1994 Abbot hybrid connectionist-HMM large vocabulary recognition system. 

    Hochberg, Mike; Cook, Gary; Renals, Steve; Robinson, Tony; Schechtman, R (1995)
  • The 1995 ABBOT LVCSR system for multiple unknown microphones 

    Kershaw, Dan; Robinson, Tony; Renals, Steve (IEEE, 1996-10)
    ABBOT is a hybrid (connectionist-hidden Markov model) large-vocabulary speech recognition (LVCSR) system, developed at Cambridge University. In this system, a recurrent network maps each acoustic vector to an estimate of ...
  • 2D Shape Classification and Retrieval 

    McNeill, Graham; Vijayakumar, Sethu (Professional Book Center, 2005-07)
    We present a novel correspondence-based technique for efficient shape classification and retrieval. Shape boundaries are described by a set of (ad hoc) equally spaced points avoiding the need to extract landmark points. ...
  • Absorbing wave makers and wide tanks 

    Salter, Stephen Hugh (Proceedings of the Conference on Directional Wave Applications, 1981-09)
    Experiments aimed at generating power from sea waves used models which sometimes reflected waves back to the wave-maker. The difficulty was avoided by changing the wave-maker control system so that it could absorb reflections. ...
  • Accent Phrase Segmentation by Finding N-Best Sequences of Pitch Pattern Templates 

    Nakai, Mitsuru; Shimodaira, Hiroshi (International Speech Communication Association, 1994-09)
    This paper describes a prosodic method for segmenting continuous speech into accent phrases. Optimum sequences are obtained on the basis of least squared error criterion by using dynamic time warping between F0 contours ...
  • Accent phrase segmentation using transition probabilities between pitch pattern templates. 

    Shimodaira, Hiroshi; Nakai, Mitsuru (International Speech Communication Association, 1993)
    This paper proposes a novel method for segmenting continuous speech into accent phrases by using a prosodic feature 'pitch pattern'. The pitch pattern extracted from input speech signals is divided into the accent segments ...
  • An accent-independent lexicon for automatic speech recognition. 

    Van Bael, Christophe; King, Simon (International Congress of Phonetic Sciences, 2003)
    Recent work at the Centre for Speech Technology Re- search (CSTR) at the University of Edinburgh has de- veloped an accent-independent lexicon for speech synthesis (the Unisyn project). The main purpose of this lexicon is ...
  • ACCOn: Checking Consistency of XML Write-Access Control Policies 

    Loreto Bravo; James Cheney; Irini Fundulaki (2008)
    XML access control policies involving updates may contain security flaws, here called inconsistencies, in which a forbidden operation may be simulated by performing a sequence of allowed operations. ACCOn implements i) ...
  • Accurate Spectral Envelope Estimation for Articulation-to-Speech Synthesis 

    Shiga, Yoshinori; King, Simon (2004-06)
    This paper introduces a novel articulatory-acoustic mapping in which detailed spectral envelopes are estimated based on the cepstrum, inclusive of the high-quefrency elements which are discarded in conventional speech ...
  • Acoustic Confidence Measures for Segmenting Broadcast News 

    Barker, Jon; Williams, Gethin; Renals, Steve (International Speech Communication Association, 1998-12)
    In this paper we define an acoustic confidence measure based on the estimates of local posterior probabilities produced by a HMM/ANN large vocabulary continuous speech recognition system. We use this measure to segment ...
  • Acoustic Space Dimensionality Selection and Combination using the Maximum Entropy Principle 

    Abdel-Haleem, Yasser H; Renals, Steve; Lawrence, Neil D (IEEE Signal Processing Society, 2004)
    In this paper we propose a discriminative approach to acoustic space dimensionality selection based on maximum entropy modelling. We form a set of constraints by composing the acoustic space with the space of phone classes, ...
  • Active Estimation of Object Dynamics Parameters with Tactile Sensors 

    Saal, Hannes; Ting, Jo-Anne; Vijayakumar, Sethu (2010)
    The estimation of parameters that affect the dynamics of objects—such as viscosity or internal degrees of freedom—is an important step in autonomous and dexterous robotic manipulation of objects. However, accurate and ...
  • Active Filtering for Robot Tactile Learning 

    Saal, Hannes; Ting, Jo-Anne; Vijayakumar, Sethu (2009)
  • Active sequential learning with tactile feedback 

    Saal, Hannes; Ting, Jo-Anne; Vijayakumar, Sethu (2010)
    We consider the problem of tactile discrimination, with the goal of estimating an underlying state parameter in a sequential setting. If the data is continuous and high- dimensional, collecting enough representative data ...
  • Activity-oriented Instant Messaging for Coalition Operations 

    Tate, Austin; Dalton, J; Potter, S (Czech Technical University Press, 2004-10)
    I-X Process Panels are used to support users who are carrying out processes and responding to events in a cooperative working environment. The panels support the tracking of personal or group issues, the planning and ...
  • Adaptive Tutorial Dialogue Systems Using Deep NLP Techniques 

    Dzikovska, Myroslava; Callaway, Charles; Farrow, Elaine; Marques-Pita, Manuel; Matheson, Colin; Moore, Johanna D. (2010-11-03)
    We present tutorial dialogue systems in two different domains that demonstrate the use of dialogue management and deep natural language processing techniques. Generation techniques are used to produce natural sounding ...
  • An advanced integrated architecture for wireless voicemail retrieval. 

    Koumpis, Konstantinos; Ladas, C; Renals, Steve (IEEE Signal Processing Society, 2001)
    This paper describes an alternative architecture for voicemail data retrieval on the move. It is comprised of three distinct components: a speech recognizer, a text summarizer and a WAP push service initiator, enabling ...
  • Age Recognition for Spoken Dialogue Systems: Do We Need It? 

    Wolters, Maria; Vipperla, Ravichander; Renals, Steve (2009)
    When deciding whether to adapt relevant aspects of the system to the particular needs of older users, spoken dialogue systems often rely on automatic detection of chronological age. In this paper, we show that vocal ageing ...
