  • Influence of variable permeability on combined free and forced convection about inclined surfaces in porous media 
    Chandrasekhara, B. C; Namboodiri, P. M. S (Elsevier, 1985-01)
    The analysis is carried out for mixed convection about inclined surfaces in a saturated porous media incorporating the variation of permeability and thermal conductivity due to packing of particles. Similarity solutions ...
  • Information flow due to controlled interference in entangled systems 
    Srikanth, R (Indian Academy of Sciences, 2002-08)
    We point out that controlled quantum interference corresponds to measurement in an incomplete basis and implies a nonlocal transfer of classical information. A test of whether such a generalized measurement is permissible ...
  • Information metamorphosis in physics and astronomy libraries 
    Louis, C; Vagiswari, A (DRTC, 2000)
    There is an enormous range of available information in the world. The role of the library is to select, acquire, organise and make available an appropriate subset of these resources. Information technology has changed ...
  • Infrared and H-alpha emission from Be stars 
    Apparao, K. M. V; Tarafdar, S. P (Astronomical Society of India, 1997)
    It was noted earlier by several authors that the infrared excess Hα emission observed from Be stars are not compatible with the idea that both emissions occur from these same optically thin ionised region. We show here ...

  • The infrared fluxes of early type stars 
    Shylaja, B. S (Astronomical Society of India, 1994)
    It is well known that the strong winds of the early type stars modify the fluxes in the infrared and radio wavelength regions. This aspect has been used here to explain the infrared fluxes by the method of 'curve of growth'. ...
