  • Equivalence of Generalized Joint Signal Representations of Arbitrary Variables 

    Sayeed, Akbar M.; Jones, Douglas L. (1996-12-20)
    Joint signal representations (JSRs) of arbitrary variables generalize time-frequency representations (TFRs) to a much broader class of nonstationary signal characteristics. Two main distributional approaches to JSRs of ...
  • The Equivalent Circuit Concept: The Current-Source Equivalent 

    Johnson, Don (2003-05-20)
    The equivalent circuit concept derives from the Superposition Principle and Ohm's Law. Two forms of the equivalent circuit, the Thevenin equivalent and the Norton equivalent, distill any linear circuit into a source and ...
  • Error control for support vector machines 

    Davenport, Mark A. (2007)
    In binary classification there are two types of errors, and in many applications these may have very different costs. We consider two learning frameworks that address this issue: minimax classification, where we seek to ...
  • Estimation-Quantization Geometry Coding Using Normal Meshes 

    Lavu, Sridhar; Choi, Hyeokho; Baraniuk, Richard G. (2003-03-01)
    We propose a new algorithm for compressing three-dimensional triangular mesh data used for representing surfaces. We apply the Estimation-Quantization (EQ) algorithm originally designed for still image compression to the ...
  • Evaluating the reliability of prototype degradable systems 

    Leuschen, Martin L.; Walker, Ian D.; Cavallaro, Joseph R. (2001-04-01)
    The technique introduced in this paper is a new technique for analyzing fault tolerant designs under considerable uncertainty, such as seen in unique or few-of-a-kind devices in poorly known environments or pre-prototype ...

    This study evaluated the in vitro and in vivo performance of antibiotic-releasing porous polymethylmethacrylate (PMMA)-based space maintainers comprising a gelatin hydrogel porogen and a poly(DL-lactic-co-glycolic acid) ...
  • Evaluation of Bone Regeneration Using the Rat Critical Size Calvarial Defect 

    Spicer, Patrick P.; Kretlow, James D.; Young, Simon; Jansen, John A.; Kasper, F. Kurtis; Mikos, Antonios G. (2012-10)
    Animal models that are reliably reproducible, appropriate analogues to the clinical condition they are used to investigate, and that offer minimal morbidity and periprocedural mortality to the subject are the keystone ...
  • Evaluation of Endothelial Cells 

    Benavides, Omar M.; Petsche, Jennifer J.; Moise, Kenneth J. Jr; Johnson, Anthony; Jacot, Jeffrey G. (2012)
    Amniotic fluid holds great promise as a stem cell source, especially in neonatal applications where autologous cells can be isolated and used. This study examined chemical-mediated differentiation of amniotic fluid-derived stem ...
  • An Evaluation of Memory Consistency Models for Shared-Memory Systems with ILP Processors 

    Pai, Vijay S.; Ranganathan, Parthasarathy; Adve, Sarita V.; Harton, Tracy (1996-10-20)

  • An Evaluation of Methods for Inferring Boolean Networks from Time-Series Data 

    Berestovsky, Natalie; Nakhleh, Luay (2013-06-21)
    Regulatory networks play a central role in cellular behavior and decision making. Learning these regulatory networks is a major task in biology, and devising computational methods and mathematical models for this task is ...
  • Evolution After Whole-genome Duplication: A Network Perspective 

    Zhu, Yun; Lin, Zhenguo; Nakhleh, Luay (2013-09-18)
    Gene duplication plays an important role in the evolution of genomes and interactomes. Elucidating how evolution after gene duplication interplays at the sequence and network level is of great interest. In this paper, ...
  • Evolution of light-induced vapor generation at a liquid-immersed metallic nanoparticle 

    Fang, Zheyu; Zhen, Yu-Rong; Neumann, Oara; Polman, Albert; de Abajo, F. Javier García; Nordlander, Peter; Halas, Naomi J. (2013)
    When an Au nanoparticle in a liquid medium is illuminated with resonant light of sufficient intensity, a nanometer scale envelope of vapor -a “nanobubble”- surrounding the particle, is formed. This is the nanoscale onset ...
  • Evolutionary processes in finite populations 

    Lorenz, Dirk M.; Park, Jeong-Man; Deem, Michael W. (2013)
    We consider the evolution of large but finite populations on arbitrary fitness landscapes. We describe the evolutionary process by a Markov-Moran process.We show that toO(1/N), the time-averaged fitness is lower for the ...
  • Examining methods for estimating mutual information in spiking neural systems 

    Rozell, Chris; Johnson, Don (2005-06-01)
    Mutual information enjoys wide use in the computational neuroscience community for analyzing spiking neural systems. Its direct calculation is difficult because estimating the joint stimulus-response distribution requires ...
  • Exceptions to the Multifractal Formalism for Discontinuous Measures 

    Riedi, Rudolf H.; Mandelbrot, Benoit (1998-01-15)
    In an earlier paper the authors introduced the <i>inverse measure</i> <i>µ</i><sup>â  </sup>(<i>dt</i>) of a given measure <i>µ</i>(<i>dt</i>) on [0,1] and presented the 'inversion formula' <i>f</i><sup>â  </sup>(<i>a</i>) ...
  • Excess noise in STM-style break junctions at room temperature 

    Chen, Ruoyu; Wheeler, Patrick J.; Natelson, D. (2012)
    Current noise in nanoscale systems provides additional information beyond the electronic conductance. We report measurements at room temperature of the nonequilibrium “excess” noise in ensembles of atomic-scale gold ...
