      Bostater, Charles R.; Huddleston, Lisa H. (2000-12-22)
      A remote sensing reflectance model, which describes the transfer of irradiant light within a homogeneous water column has previously been used to simulate the nadir viewing reflectance just above or below the water surface ...
    • Layered unequal loss protection for image transmission over packet loss channels with delay constraints 

      Cai, Jianfei; Li, Xiangjun; Chen, Chang Wen (2004-10-25)
      In the case of high bit rate image transmission or having lots of packets, the FEC (forward error correction) encoding and decoding processes in the ULP (unequal loss protection) based schemes should be applied to individual ...
    • Layered unequal loss protection for progressive image transmission over packet loss channels 

      Cai, Jianfei; Li, Xiangjun; Chen, Chang Wen (2004-01-18)
      In the past, many schemes have been proposed for progressive image transmission using unequal error protection (UEP) or unequal loss protection (ULP). However, most existing UEP/ULP schemes do not consider the minimum image ...
    • The lightning-TGF relationship on microsecond timescales 

      Cummer, Steven A.; Lu, Gaopeng; Briggs, Michael S.; Connaughton, Valerie; Xiong, Shaolin; Fisherman, Gerald Jerry; Dwyer, Joseph R. (2011-07-28)
      We analyze the count rates of two terrestrial gamma-ray flashes (TGFs) detected by the Fermi Gamma-ray Burst Monitor (GBM) with the broadband magnetic fields (1 to 300 kHz) produced by the simultaneous lightning processes. ...
    • Limits on spacetime foam 

      Christiansen, Wayne A.; Ng, Yeejack; Floyd, David J. E.; Perlman, Eric S. (2011-04-04)
      Plausibly spacetime is foamy on small distance scales, due to quantum fluctuations. We elaborate on the proposal to detect spacetime foam by looking for seeing disks in the images of distant quasars and active galactic ...
    • Line detection using Wavelet filters 

      Udomhunsakul, Somkait; Kozaitis, S.P.; Sritheeravirojana, Uthai Thai (2003-09-25)
      We proposed a new line detection method in noisy images using Mexican hat wavelet filters. In our approach, we applied the wavelet transform in a multiresolution sense by forming the products of wavelet coefficients at the ...

      Kozaitis, S.P.; Cofer, Rufus H. (2003-08-14)
      We detected roads in aerial imagery using a method based on lineal feature detection. Our method used the products of wavelet coefficients at several scales were to identify and locate lineal features. Using our approach ...

      Kozaitis, S.P.; Udomhunsakul, Somkait; Cofer, Rufus H.; Agarawal, A.; Song, Shuwu (2002-08-06)
      We detected roads in aerial imagery based on multiresolution linear feature detection. Our method used the products of wavelet coefficients at several scales to identify and locate linear features. After detecting possible ...
    • Linear functional differential equations possessing solutions with a given growth rate 

      Agarwal, Ravi P.; Rontó, András (2005-02-01)
      We establish optimal, in a sense, conditions under which, for arbitrary forcing terms from a suitable class, a linear inhomogeneous functional differential equation in a preordered Banach space possesses solutions satisfying ...
    • Location-specific responses to thermal stress in larvae of the reef-building coral Montastraea faveolata 

      Polato, Nicholas R.; Voolstra, Christian; Schnetzer, Julia; DeSalvo, Michael K.; Randall, Carly J.; Szmant, Alina M.; Medina, Mónica; Baums, Iliana B. (2010-06-23)
      The potential to adapt to a changing climate depends in part upon the standing genetic variation present in wild populations. In corals, the dispersive larval phase is particularly vulnerable to the effects of environmental ...
    • Long-range and short-range dihadron angular correlations in central PbPb collisions at psNN = 2:76 TeV 

      Chatrchyan, S.; Khachatryan, Vardan; Sirunyan, A.M.; Baarmand, Marc M.; Dorney, B.; Guragain, Samir; Hohlmann, Marcus; Kalakhety, Himali; Ralich, Robert M.; Vodopiyanov, Igor (2011-07-18)
      First measurements of dihadron correlations for charged particles are presented for central PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV over a broad range in relative pseudorapidity (∆η) and the ...
