    Peraiah, A; Nagendra, K. N (Kluwer Academic Publishers, 1983-02)
    Simultaneous solutions of the radiative transfer equation in the comoving frame and the statistical equilibrium equation, for a non-LTE two-level atom, have been obtained by means of angle-averaged partial frequency ...
  • Effects on solar structure of opacity changes 
    Tripathy, S. C; Christensen-Dalsgaard, J (Astronomical Society of India, 1996)
    We investigate the sensitivity of solar structure to localized changes in opacity by considering differences between models computed with locally modified opacity and unmodified references models. The results confirm that ...

  • Efficient minimization of servo lag error in adaptive optics using data stream mining 
    Vyas, A; Roopashree, M. B; Prasad, B. R (Springer, 2011)
    Prediction of the wavefronts helps in reducing the servo lag error in adaptive optics caused by finite time delays (~ 1-5 ms) before wavefront correction. Piecewise linear segmentation based prediction is not suitable in ...
