  A projective network model is a model that enables predictions to be made based on a subsample of the network data, with the predictions remaining unchanged if a larger sample is taken into consideration. An exchangeable ...
• Spectra of amplitude-perturbed glottal waveforms 

  Walker, Jacqueline; Murphy, Peter (2001)

  The spectral description of voice aperiodicities is important for the introduction of refined voice synthesis parameters and for quantifying voice disorders. A quantitative analysis of the spectral properties of glottal ...
• Experimental and simulation study for commercial time transfer service over geostationary satellite 

  Walker, Jacqueline; Genova, Marco (2012)

  Time transfer over satellite links has been explored since the satellite era began. Currently, TWSTFT is routinely used between national timing laboratories to align national timing standards and the GPS provides precise ...
• Modeling the effect of nonideal reference clocks on the jitter generated in timing transfer 

  Walker, Jacqueline; Cantoni, Antonio (IEEE Computer Society, 2007)

  In constant bit-rate timing transfer, the reference clocks which encode and reconstruct the service clock at origin and destination may be jittered. We present new, straightforward approaches to finding and visualizing ...
• Experimental evaluation of the jitter generated in timing transfer 

  Walker, Jacqueline; Cantoni, Antonio (IEEE Computer Society, 2010)

  Modern telecommunications networks maintain synchronization and distribute accurate timing information using approaches with strict requirements on clock quality and jitter and wander at interfaces. In the future, packet ...
• Experimental and simulation study for commercial time transfer service over geostationary satellite 

  Walker, Jacqueline; Genova, Marco (Taylor and Francis Ltd, 2013)

  Time transfer over satellite links has been explored since the satellite era began. Currently, Two Way Satellite Time and Frequency Transfer (TWSTFT) is routinely used between national timing laboratories to align national ...
• Simulation study for commercial time transfer service over geostationary satellite 

  Walker, Jacqueline; Genova, Marco (IEEE Computer Society, 2013)

  Over the last twenty years, many technologies and services have come to rely on the GPS for precise timing. Concern is increasing about the wisdom of being reliant on a single timing solution provided by a single country ...
• Cepstrum of bispectrum - a new approach to blind system reconstruction 

  Shahid, Shahjahan; Walker, Jacqueline (Elsevier, 2008)

  In this paper, an improved approach to blind deconvolution of LTI systems incorporating phase unwrapping is presented. The method can recover a noise-free estimate of the logarithm of the system transfer function which ...
• The complex cepstrum of bicepstrum for system reconstruction with application to sEMG signal 

  Shahid, Shahjahan; Walker, Jacqueline (2003)

  Surface electromyography (sEMG) provides information about the performance of muscles and nerves. An sEMG signal can be modelled as a sum of filtered random impulse processes. The Bispectrum suppresses Gaussian noise ...
• Application of bispectrum based signal reconstruction to sEMG signal 

  Shahid, Shahjahan; Walker, Jacqueline (2001)

  The surface electromyogram (sEMG) conveys information about the physiological properties of muscles. Unlike the power spectrum, the bispectrum can suppress noise when characterizing non-Gaussian random signals. In this ...
• Time domain attack and release modeling - applied to spectral domain sound synthesis 

  Kreutzer, Cornelia; Walker, Jacqueline; O'Neill, Michael (2008)

  We introduce a time-domain model for the synthesis of attack and release parts of musical sounds. This approach is an extension of a spectral synthesis model we developed: the Parametric Synthesis Model (PSM). The attack ...
• Minimal climate change impacts on natural organic matter forecasted for a potable water supply in Ireland 

  O'Driscoll, Connie; Ledesma, José L. J.; Coll, John; Murnane, John G.; Nolan, Paul; Mockler, Eva M.; Futter, Martyn N.; Xiao, Liwen W. (Elsevier, 2018)

  Natural organic matter poses an increasing challenge to water managers because of its potential adverse impacts on water treatment and distribution, and subsequently human health. Projections were made of impacts of climate ...
• Evaluation of olive pomace in the production of novel broilers with enhanced in vitro antithrombotic properties 

  Nasopoulou, Constantina; Lytoudi, Konstantina; Zabetakis, Ioannis (Wiley and Sons Ltd, 2018)

  Several attempts have been made not only to improve nutritional value of broilers but also to attenuate dependence on raw materials such as corn in compounded broilers feed. Therefore the aim of this study was to ...
• Can large oceanic vortices be stable? 

  Benilov, Eugene (American Geophysical Union (AGU), 2018)

  Observations show that radii of oceanic eddies often exceed the Rossby radius of deformation, whereas theoretical studies suggest that such vortices should be unstable. The present paper resolves this paradox by presenting ...
