Line widths in the 1-0 and 2-0 bands of HF due to a standard atmosphere of argon, krypton, and xenon have been measured. Results in the 1-0 band are similar to those seen in HCl. In the 2-0 band the widths increase at high J values for the heavier perturbers and show a significant decrease with increasing temperature. Results of line shift measurements in the 2-0 band corroborate the measurements of Jaffe, Rosenberg, Hirschfeld, and Gailar and indicate that the shifts are not proportional to the vibrational quantum number of the upper state or to the polarizability of the perturbing gas.
Dim target detection and tracking algorithm based on the empirical mode decomposition (EMD) is proposed. EMD is introduced to decompose Ugg Outlet England
the original image into a definite number of high frequency and low frequency components by means of sifting. With the EMD algorithm, it is valid to estimate the background and get the dim target by removing the background from the original image. The algorithm detects dim moving target effectively and estimate its trajectory accurately. The data analysis and Genuine Uggs Uk Retailers
experiments show that the proposed algorithm is adaptable to real-time target detection and tracking.
