  • Joint adaptive modulation and diversity combining with feedback error compensation 
    Choi, Seyeong; Yang, Hong-Chuan; Alouini, Mohamed-Slim; Qaraqe, Khalid A. (2008-08-08)
    This report investigates the effect of feedback error on the performance of the joint adaptive modulation and diversity combining (AMDC) scheme which was previously studied with an assumption of error-free feedback ...
  • Near-end crosstalk cancellation in xDSL systems 
    Nongpiur, Rajeev Conrad (2008-12-18)
    In xDSL technology, high-speed data are transferred between the central office and the customers, or between two or more central offices using unshielded telephone lines. A major impairment that hinders the increase in ...
  • Music genre classification of audio signals 
    Tzanetakis, George; Perry, Cook (IEEE, 2002-07)
    Musical genres are categorical labels created by humans to characterize pieces of music. A musical genre is characterized by the common characteristics shared by its members. These characteristics typically are related ...
  • Motion in casual InfoVis and the interrelation between personality, performance, and preference 
    Sprague, David; Tory, Melanie (2009-06-02)
    Current real-world casual information visualization systems use motion to presumably increase system appeal and repeated use. Despite empirical evidence suggesting that motion is distracting and not particularly good for ...
  • Measurement of sound-speed gradients in deep-ocean sediments usingl_{1}deconvolution techniques 
    Chapman, N; Barrodale, I; Zala, C (IEEE, 1984)
    A method is described for measuring the sound speed and the sound-speed gradient of surficial sea floor sediment from bottom-reflected signals recorded in marine seismic experiments. The technique makes use of the ocean-bottom ...
  • On the rate of growth of condition numbers for convolution matrices 
    Milinazzo, F; Zala, C; Barrodale, I (IEEE, 1987)
    When analyzing linear systems of equations, the most important indicator of potential instability is the condition number of the matrix. For a convolution matrix W formed from a series w (whereW_{ij} = w_{i-j+1}, 1 leq i-j ...
  • Maximum entropy image processing using transform domain constraints 
    Zala, C A; Barrodale, I; Lucas, C E; MacKinnon, R F (IEEE, 1989)
    A formulation of the maximum entropy (ME) method is described, where the data constraints are expressed in the form of fixed bounds on the elements of an orthogonal transform of the model. The bounds are set on the basis ...
  • On the movement of robot arms in 2-dimensional bounded regions 
    Hopcroft, John; Joseph, Deborah; Whitesides, Sue (IEEE, 1982)
    The classical mover's problem is the following: can a rigid object in 3-dimensional space be moved from one given position to another while avoiding obstacles? It is known that a more general version of this problem involving ...
  • High-resolution signal and noise field estimation using the L 1 (least absolute values) norm 
    Zala, C; Barrodale, I; Kennedy, J (IEEE, 1987)
    In this paper a new method for obtaining a quantitative estimate of an acoustic field consisting of a set of discrete sources and background noise is described. The method is based on theL1 (least absolute values) norm ...
  • Integrating region and edge information for the automatic segmentation of interventional magnetic resonance images of the shoulder complex 
    Tremblay, ME; Branzan Albu, A; Hebert, L; Laurendeau, D (IEEE, 2004)
    This paper proposes a new 2D segmentation method for MR shoulder images. Due to the significant length of the image sequences, we aim at minimizing the user intervention in the segmentation process. Our method integrates ...
  • Virtualized recomposition: Cloudy or clear? 
    Matthews, C; Coady, Y (IEEE, 2009-05-23)
    Virtualization provides a coarse-grained isolation mechanism that results in large systems, with full operating systems and a complete software stack as their foundation. Though much of this foundation is not strictly ...
  • SPARCS from the University of Victoria: supporting sustainable and integrated outreach activities for educators and young minds 
    Murdoch, J; St. Pierre, A; Coady, Y; Carruthers, S; Gibbs, C; Lonergan, S; Srivastava, Gautam; Stege, U; Yazir, O (IEEE, 2008)
    Although IT industry is flourishing, student enrolment in Computer Science and related Engineering post-secondary degree programs is low. The causes and issues surrounding this trend are diverse, inter-related, and vastly ...
  • Quantifying artifacts of virtualization: a framework for mirco-benchmarks (sic) 
    Matthews, C; Coady, Y; Neville, S (IEEE, 2009)
    One of the novel benefits of virtualization is its ability to emulate many hosts with a single physical machine. This approach is often used to support at-scale testing for large-scale distributed systems. To better ...
  • Living with the law: Can automation give us Moore with less? 
    Gibbs, C; Baldwin, J; Singh, N; D'Hondt, M; Coady, Y (IEEE, 2008)
