    • What is Simulated Annealing? 

      Trosset, Michael W. (2000-02)
      Beginning in 1983, simulated annealing was marketed as a global optimization methodology that mimics the physical annealing process by which molten substances cool to crystalline lattices of minimal energy. This marketing ...

      With funding for services like MOSIS shrinking and industry demanding more diverse skills, the microelectronics education infrastructure—indeed that of engineering education in general—is under intense pressure to change. ...
    • When does interval coding occur? 

      Johnson, Don; Glantz, Raymon (2003-07-20)
      During the stationary portion of neuron's spiking response to a stimulus, the stimulus could be coded in the average rate and, more elaborately, in the statistics of the sequence of interspike intervals. We use information ...
    • When is Missing Data Recoverable? 

      Zhang, Yin (2006-10)
      Suppose a non-random portion of a data vector is missing. With some minimal prior knowledge about the data vector, can we recover the missing portion from the available one? In this paper, we consider a linear programming ...

    • Whole-Genome Sequence of the 1,4-Dioxane-Degrading Bacterium Mycobacterium dioxanotrophicus PH-06 

      He, Ya; Wei, Kangfei; Si, Kaiwei; Mathieu, Jacques; Li, Mengyan; Alvarez, Pedro J.J. (2017)
      We report here the complete genome sequence of Mycobacterium dioxanotrophicus PH-06, which is capable of using 1,4-dioxane as a sole source of carbon and energy. The reported sequence will enable the elucidation of this ...
    • Why Is Modal Logic So Robustly Decidable? 

      Vardi, Moshe Y. (1997-04-12)
      In the last 20 years modal logic has been applied to numerous areas of computer science, including artificial intelligence, program verification, hardware verification, database theory, and distributed computing. There are ...
    • Why Zeolites Have So Few 7-Membered Rings 

      Li, Xi; Deem, Michael W. (2014)
      Known zeolite structures have relatively few 7-membered rings. Previous quantum mechanical calculations suggest there is no particular energy penalty for 7-membered rings. Predicted zeolite structures sampled from all ...
    • Wigner-Based Formulation of the Chirplet Transform 

      Baraniuk, Richard G.; Jones, Douglas L. (1996-12-01)
      Using the Wigner distribution, we derive and analyze a matrix formulation for the chirplet transform, a signal analysis tool that generalizes the wavelet and short-time Fourier transforms. The formulation expresses the ...
    • Wigner-Ville Spectrum Estimation via Wavelet Soft-Thresholding 

      Baraniuk, Richard G. (1994-10-01)
      The high noise sensitivity of the Wigner distribution makes smoothing a necessity for producing readable time-frequency images of noise corrupted signals. Since linear smoothing suppresses noise at the expense of considerable ...
    • WInHD: Wavelet-based Inverse Halftoning via Deconvolution 

      Neelamani, Ramesh; Nowak, Robert David; Baraniuk, Richard G. (2002-10-20)
      We propose the <i>Wavelet-based Inverse Halftoning via Deconvolution</i> (WInHD) algorithm to perform inverse halftoning of error-diffused halftones. WInHD is motivated by our realization that inverse halftoning can be ...
    • Wireless @ Wired Speeds 

      Steger, Christopher; Chakrabarti, Arnab (2004-12-01)
      This is a poster from the first 100x100 project meeting. It outlines some basic concepts in MIMO algorithm and system design at a relatively high, accessible level.
    • Wireless Downlink Schemes in a Class of Frequency Selective Channels with Uncertain Channel State Information 

      Steger, Christopher (2004-04-01)
      The fourth generation of cellular wireless technology will be called upon to perform at data rates far exceeding those of any existing system. The most fundamental decision in the design of the physical layer of 4G wireless ...
