  • New Dimensions In Wavelet Analysis 

    Baraniuk, Richard G.; Jones, Douglas L. (1992-03-01)
    In this paper we propose a new class of signal analysis tools that generalizes the popular wavelet and short-time Fourier transforms. The class allows skews and rotations of the analyzing wavelet in the time-frequency ...

    Visinsky, Monica L.; Walker, Ian D.; Cavallaro, Joseph R. (1994-05-01)
    Autonomous robotic fault detection is becoming increasingly important as robots are used in more inaccessible and hazardous environments. Detection algorithms, however, are adversely effected by the model simplification, ...
  • New Estimation Techniques for a class of chaotic signals 

    Rajan, Dinesh; Aazhang, Behnaam (2000-06-20)
    We propose a new technique for estimation of chaotic signals in the presence of additive noise. The new method uses statistical measures to restrict the space over which the signals are received. The proposed technique ...
  • A New Framework for Complex Wavelet Transforms 

    Fernandes, Felix; van Spaendonck, Rutger; Burrus, C. Sidney (2003-06-20)
    Although the Discrete Wavelet Transform (DWT) is a powerful tool for signal and image processing, it has three serious disadvantages: shift sensitivity, poor directionality and lack of phase information. To overcome these ...

    Casillas, Gilberto; Mayoral, Alvaro; Liu, Mingjie; Ponce, Arturo; Artyukhov, Vasilii I.; Yakobson, Boris I.; Jose-Yacaman, Miguel (2014)
    Atomic carbon chains have raised interest for their possible applications as graphene interconnectors as the thinnest nanowires; however, they are hard to synthesize and subsequently to study. We present here a reproducible ...

    Erdelyi, Miklos; Sengupta, Chaitali; Bor, Zsolt; Cavallaro, Joseph R.; Kido, Motoi; Smayling, Michael C.; Tittel, Frank K.; Wilson, William L.; Szabo, Gabor (1995-02-01)
    This paper reports recent progress in achieving sub-half-micron feature sizes with UV laser illumination based on a novel interferometric phase shifting (IPS) technique. In the IPS arrangement, the intensity and amount of ...
  • A new look at the informational gain of soft decisions 

    Lexa, Michael; Johnson, Don (2003-04-20)
    This paper develops a new systematic method of studying the benefits of 2-bit soft decisions by applying the concepts of information processing theory. We quantify performance in terms of the information transfer ratio and ...
  • A New MIMO Detector Architecture Based on A Forward-Backward Trellis Algorithm 

    Sun, Yang; Cavallaro, Joseph R. (2008-10-01)
    In this paper, a recursive Forward-Backward (F-B) trellis algorithm is proposed for soft-output MIMO detection. Instead of using the traditional tree topology, we represent the search space of the MIMO signals with a fully ...
  • New multivariate dependence measures and applications to neural ensembles 

    Goodman, Ilan; Johnson, Don (2003-09-20)
    We develop two new multivariate statistical dependence measures. The first, based on the Kullback-Leibler distance, results in a single value that indicates the general level of dependence among the random variables. The ...
  • A New Phase Shifting Method for High Resolution Microlithography 

    Kido, Motoi; Cavallaro, Joseph R.; Szabo, Gabor; Wilson, William L.; Tittel, Frank K. (1994-01-01)
    One of the most promising lithographic technique for the future designs of DRAMs is the phase-shifting mask technique. Conventional phase shifting-masks, however, are difficult to fabricate as they require regions of ...
  • A New Phase Shifting Technique for Deep UV Excimer Laser Based Lithography 

    Bor, Zsolt; Cavallaro, Joseph R.; Erdelyi, Miklos; Kido, Motoi; Sengupta, Chaitali; Smayling, Michael; Szabo, Gabor; Tittel, Frank; Wilson, William (1995-02-01)

    Baraniuk, Richard G.; Jones, Douglas L. (1992-10-01)
    The discretization of the metaplectic transform (MT) is considered, and it is shown that it can lead to completely new orthonormal bases (ONBs) for the signal space of square integrable functions. Two new classes of bases, ...
