    • Noise suppression and motion estimation in medical ultrasound imaging 

      Yue, Yong (2007)
      Echocardiographic imaging is a primary modality in the diagnosis of heart disease. Compared to other imaging techniques, such as X-Ray, MRI, and PET, ultrasound imaging owes its great popularity to the fact that it is a ...
    • Non-coherent and partially coherent space-time constellations 

      Borran, Mohammed Jaber (2004)
      With the rapid growth of wireless networks and multimedia applications, next generation cellular systems are expected to support data rates that are orders of magnitude higher than those currently available. Due to the ...
    • Non-coherent and Partially Coherent Space-Time Constellations 

      Borran, Mohammad Jaber (2003-06-01)
      With the rapid growth of wireless networks and multimedia applications, next generation cellular systems are expected to support data rates that are orders of magnitude higher than those currently available. Due to the ...
    • Non-Gaussian Markov time series 

      Rao, Srinivasa Patibandla (1988)
      Time series are often modeled as filtered versions of white noise, the filter being linear. We study non-Gaussian processes by modeling them similarly, but allowing the possibility of the filter being non-linear. These ...
    • Non-intrusive Persistence with a Backend NVM Controller 

      Pu, Libei; Doshi, Kshitij; Giles, Ellis; Varman, Peter (2015)
      By providing instruction-grained access to vast amounts of persistent data with ordinary loads and stores, byte-addressable storage class memory (SCM) has the potential to revolutionize system architecture. We describe a ...
    • Non-invasive IC tomography using spatial correlations 

      Shamsi, Davood (2010)
      We introduce a new methodology for post-silicon characterization of the gate-level variations in a manufactured Integrated Circuit (IC). The estimated characteristics are based on the power and the delay measurements that ...
    • Non-monotonic Response to Monotonic Stimulus: Regulation of Glyoxylate Shunt Gene-Expression Dynamics inᅠ Mycobacterium tuberculosis 

      Ascensao, Joao A.; Datta, Pratik; Hancioglu, Baris; Sontag, Eduardo; Gennaro, Maria L.; Igoshin, Oleg A. (2016)
      Understanding how dynamical responses of biological networks are constrained by underlying network topology is one of the fundamental goals of systems biology. Here we employ monotone systems theory to formulate a theorem ...
    • Non-Redundant, Linear-Phase, Semi-Orthogonal, Directional Complex Wavelets 

      Fernandes, Felix; Wakin, Michael; Baraniuk, Richard G. (2004-05-01)
      The directionality and phase information provided by non-redundant complex wavelet transforms (NCWTs) provide significant potential benefits for image/video processing and compression applications. However, because existing ...
    • Noncoherent image denoising 

      Hua, Gang (2005)
      The techniques of Translation Invariant (TI) denoising and statistical modeling are widely used in image denoising. This thesis studies how these techniques exploit location information in images and identifies a class of ...
    • Nonlinear Dynamic Theory for Photorefractive Phase Hologram Formation 

      Kim, Dae M.; Shah, Rajiv R.; Rabson, Thomas A.; Tittel, Frank K. (1976-01-20)
      A nonlinar dynamic theory is developed for the formation of photorefractive volume phase holograms. A feedback mechanism existing between the photo-generated field and free electron density, treated explicitly yields the ...
    • Nonlinear elastic buckling and postbuckling analysis of cylindrical panels 

      Zhou, Yang; Stanciulescu, Ilinca; Eason, Thomas; Spottswood, Michael (2015)
      This paper revisits the buckling analysis of a benchmark cylindrical panel undergoing snap-through when subjected to transverse loads. We show that previous studies either overestimated the buckling load and identified a ...
    • Nonlinear Fault Detection for Hydraulic Systems 

      Leuschen, Martin L.; Walker, Ian D.; Cavallaro, Joseph R. (2003-01-01)
      One of the most important areas in the robotics industry is the development of robots capable of working in hazardous environments. As humans cannot safely or cheaply work in these environments, providing a high level ...
    • Nonlinear Fault Detection for Hydraulics: Recent Advances in Fault Diagnosis and Fault Tolerance for Mechatronic Systems 

      Leuschen, Martin L.; Walker, Ian D.; Cavallaro, Joseph R. (2002-10-01)
      One of the most important areas in the robotics industry is the development of robots capable of working in hazardous environments. As humans cannot safely or cheaply work in these environments, providing a high level ...
    • Nonlinear neural codes 

      Yang, Qianli (2015-12-03)
      Most natural task-relevant variables are encoded in the early sensory cortex in a form that can only be decoded nonlinearly. Yet despite being a core function of the brain, nonlinear population codes are rarely studied and ...
    • Nonlinear phase FIR filter design with minimum LS error and additional constraints 

      Lang, Markus; Bamberger, Joachim (1994-07-01)
      We examine the problem of approximating a complex frequency response by a real-valued FIR filter according to the <i>L<sub>2</sub></i> norm subject to additional inequality constraints for the complex error function. ...
    • Nonlinear Processing of a Shift Invariant DWT for Noise Reduction 

      Lang, Markus; Guo, Haitao; Odegard, Jan E.; Burrus, C. Sidney; Wells, R.O. (1995-03-20)
      A novel approach for noise reduction is presented. Similar to Donoho, we employ thresholding in some wavelet transform domain but use a nondecimated and consequently redundant wavelet transform instead of the usual orthogonal ...
