    • Compound Poisson Cascades 

      Chainais , Pierre; Riedi, Rudolf H.; Abry, Patrice (2002-05-01)
      Multiplicative processes and multifractals proved useful in various applications ranging from hydrodynamic turbulence to computer network traffic, to name but two. Placing multifractal analysis in the more general framework ...
    • A Comprehensive Probabilistic Framework to Learn Air Data from Surface Pressure Measurements 

      Srivastava, Ankur; Meade, Andrew J. (2015)
      Use of probabilistic techniques has been demonstrated to learn air data parameters from surface pressure measurements. Integration of numerical models with wind tunnel data and sequential experiment design of wind tunnel ...
    • Compressed Sensing for Imaging Applications 

      Takhar, Dharmpal (2008)
      Compressed sensing is a new sampling theory which allows reconstructing signals using sub-Nyquist measurements. This can significantly reduce the computation re­quired for both image and video whether during acquisition ...
    • Compressed strip: The deceleration of the automobile 

      Cruz, Maria del Carmen (2000)
      I am interested in erasing the disparity between the body and the automobile by allowing both to participate in a new and common public space simultaneously. This new public space incorporates various diverse models of ...
    • Compressibility of a Fermionic Mott Insulator of Ultracold Atoms 

      Duarte, Pedro M.; Hart, Russell A.; Yang, Tsung-Lin; Liu, Xinxing; Paiva, Thereza; Khatami, Ehsan; Scalettar, Richard T.; Trivedi, Nandini; Hulet, Randall G. (2015)
      We characterize the Mott insulating regime of a repulsively interacting Fermi gas of ultracold atoms in a three-dimensional optical lattice. We use inᅠsitu imaging to extract the central density of the gas and to determine ...
    • Compressing Piecewise Smooth Multidimensional Functions Using Surflets: Rate-Distortion Analysis 

      Chandrasekaran, Venkat; Wakin, Michael; Baron, Dror; Baraniuk, Richard G. (2004-03-01)
      Discontinuities in data often represent the key information of interest. Efficient representations for such discontinuities are important for many signal processing applications, including compression, but standard Fourier ...
    • Compression Color Space Estimation of JPEG Images using Lattice Basis Reduction 

      Neelamani, Ramesh; Baraniuk, Richard G.; de Queiroz, Ricardo (2001-10-01)
      Given a color image that was previously JPEG-compressed in some hidden color space, we aim to estimate this unknown compression color space from the image. This knowledge is potentially useful for color image enhancement ...
    • Compression induced stiffening and alignment of liquid crystal elastomers 

      Verduzco, Rafael; Agrawal, Aditya; Chipara, Alin Cristian (2016-02-16)
      In some embodiments, the present disclosure provides methods of strengthening liquid crystal elastomers. In some embodiments, such methods include a step of placing the liquid crystal elastomer in an environment that applies ...
    • Compression of femtosecond krypton fluoride excimer laser pulses 

      Cote, Frederic (1993)
      Temporal characteristics of compressed femtosecond KrF pulses are measured with the help of a single-shot phase-sensitive autocorrelator for the UV. The performance of a prism compressor and the influence of higher order ...
