  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Coady, Y; Ong, JS; Feeley, MJ (IEEE, 1999)
    Advances in network technology continue to improve the communication performance of workstation and PC clusters, making high-performance workstation-cluster computing increasingly viable. These hardware advances, however, ...
  • Wang, JYQ; Ong, JS; Coady, Y; Feeley, MJ (IEEE, 2000)
    The benefits of Markov-based predictive prefetching have been largely overshadowed by the overhead required to produce high-quality predictions. While both theoretical and simulation results for prediction algorithms ...
  • Coady, Y; Kiczales, G; Feeley, M; Hutchinson, N; Ong, JS; Gudmundson, S (IEEE, 2001)
    Operating system structure is important; it leads to understandable, maintainable, 'pluggable' code. But despite our best efforts, some system elements have been difficult to structure. We propose a new analysis of this ...
  • 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 ...
  • Rowe, A.M.; Barclay, J.A. (American Institute of Physics, 2003)
    The active magnetic regenerator (AMR) uses a magnetic solid as a thermal storage medium and as a working material in a refrigeration cycle. Thermodynamically coupled to a heat transfer fluid, the regenerator produces a ...
  • Richard, M.-A.; Rowe, A.M.; Chahine, R. (American Institute of Physics, 2004)
    An investigation of active magnetic regenerators (AMRs) has been performed near room temperature using helium as a heat transfer fluid and a magnetic field of 2 T. To evaluate the impact of the operating conditions, the ...
  • 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 ...
  • Li, Wei; Gulliver, T. Aaron (Hindawi Publishing Corporation, 2004-02-29)
    We introduce a new successive interference cancellation (SIC) technique for direct sequence code division multiple access (DSCDMA) systems with transmit diversity. The transmit diversity is achieved with a space-time block ...
  • Dechev, Nikolai; Cleghorn, William L.; Mills, James K. (Institute of Electrical and Electronics Engineers (IEEE), 2004-04)
    This paper describes a novel microassembly system that can be used to construct out-of-plane three-dimensional (3-D) microstructures. The system makes use of a surface-micromachined microgripper that is solder bonded to a ...
  • Xiao, Yang; Li, Haizhon; Pan, Yi; Wu, Kui; Li, Jie (IEEE, 2004-11)
    To reduce energy consumption (EC), a mobile handset system can be designed in such a way that while the data-receiving unit in a mobile handset is receiving and monitoring data packets, the rest part of the handset (i.e., ...
  • Bergen, Stuart W. A.; Antoniou, Andreas (Hindawi Publishing Corporation, 2005)
    An efficient method for the design of nonrecursive digital filters using the ultraspherical window function is proposed. Economies in computation are achieved in two ways. First, through an efficient formulation of the ...
  • Rankin, David M.; Gulliver, T. Aaron; Taylor, Desmond P. (Hindawi Publishing Corporation, 2005)
    The parallel and serial concatenation of codes is well established as a practical means of achieving excellent performance. In this paper, we introduce the parallel and serial concatenation of single parity check (SPC) ...
  • Ramachandran, Parameswaran (2005)
    The application of digital signal processing (DSP) for the identification of the locations of hot spots in proteins is explored. DSP provides a natural framework for analyzing biologi¬cal sequence information due to the ...
  • Sethakaset, Ubolthip; Gulliver, T. Aaron (Hindawi Publishing Corporation, 2005)
    We propose a novel differential amplitude pulse-position modulation (DAPPM) for indoor optical wireless communications. DAPPM yields advantages over PPM, DPPM, and DH-PIMα in terms of bandwidth requirements, capacity, and ...
  • Gibbs, C; Coady, Y (IEEE, 2005)
    With the constant demand for system change and upgrades comes the need to simplify and ensure accuracy in this process. As structural boundaries decay, non-local modifications compound the costs of system evolution and ...
