  • Empirical detection for spread spectrum and code division multiple access (CDMA) communications 

    Lee, Yuan Kang (1998)
    In this thesis, the method of "classification with empirically observed statistics"--also known as empirical classification, empirical detection, universal classification, and type-based detection--is configured and applied ...
  • Empirical Mode Decomposition Based Frequency Attributes 

    Magrin-Chagnolleau, Ivan; Baraniuk, Richard G. (1999-11-01)
    This paper describes a new technique, called <i>Empirical Mode Decomposition</i> (EMD), which allows the decomposition of one-dimensional signals into intrinsic oscillatory modes. Each component, called <i>Intrinsic Mode ...
  • Energy Accounting and Optimization for Mobile Systems 

    Dong, Mian (2013-09-16)
    Energy accounting determines how much a software process contributes to the total system energy consumption. It is the foundation for evaluating software and has been widely used by operating system based energy management. ...

    Off-axis illumination is a promising optical microlithography technique which can be used to improve the image quality of line-space patterns. With this method the image is produced by the zero and first order diffracted ...
  • Enhanced noise at high bias in atomic-scale Au break junctions 

    Chen, Ruoyu; Wheeler, Patrick J.; Di Ventra, M.; Natelson,D. (2014)
    Heating in nanoscale systems driven out of equilibrium is of fundamental importance, has ramifications for technological applications, and is a challenge to characterize experimentally. Prior experiments using nanoscale ...
  • Enhanced Power Efficiency of Mobile OFDM Radio using Pre-distortion and Post-compensation 

    Guo, Yuanbin; Cavallaro, Joseph R. (2002-09-20)
    High power efficiency is an important requirement in cellular transmitter radios. OFDM systems require very linear transmission because of high peak-to-average power-ratio (PAPR). However, linear power amplifiers (PA) have ...
  • Enhanced Pseudo Power Signatures for Nonstationary Signal Classification: The Projector Approach 

    Venkatachalam, Vidya; Aravena, Jorge.L. (1999-05-01)
    The classification of nonstationary signals of unknown duration is of great importance in areas like oil exploration, moving target detection, and pattern recognition. In an earlier work, we provided a solution to this ...
  • Enhanced signatures for event classification: The projector approach 

    Venkatachalam, Vidya; Aravena, Jorge.L. (1998-10-01)
    The classification of nonstationary signals of unknown duration is of great importance in areas like oil exploration, moving target detection, and pattern recognition. In an earlier work, we provided a solution to this ...
  • Enhanced VLSI Manufacturability Using an Integrated CAD Framework 

    Fossati, Humberto M.; Tittel, Frank K.; Wilson, William L.; Cavallaro, Joseph R. (1994-01-01)
    Continued improvements in VLSI performance, circuit density and production costs are possible, in part, do to significant advances in lithography. As feature sizes get smaller, design houses are faced with either improving ...
  • Enhancement of Decompressed Images at Low Bit Rates 

    Gopinath, Ramesh A.; Lang, Markus; Guo, Haitao; Odegard, Jan E. (1994-07-20)
    Transform coding at low bit rates introduces artifacts associated with the basis functions of the transform. For example, decompressed images based on the DCT (discrete cosine transform)- like JPEG<sup>16</sup> - exhibit ...
  • 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 ...

    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 ...
