Modification of black-body radiance at low temperatures and frequencies
, 2010 In contrast to earlier reports, where the spectrum of the {\sl energy density} of photonic black-body radiation modified by SU(2) effects was discussed, we discuss the low-frequency spectrum of the {\sl radiance} at temperatures ranging between 5 and 20 ...

Tropospheric monitoring technology for gravity wave experiments [PDF]
Tropospheric refractivity fluctuations are an important error source for gravity wave detection by Doppler tracking in that they alter the phase and phase rate of electromagnetic signals. Estimates are presented of the effect of tropospheric fluctuations

Results of precision processing (scene correction) of ERTS-1 images using digital image processing techniques [PDF]
ERTS-1 MSS and RBV data recorded on computer compatible tapes have been analyzed and processed, and preliminary results have been obtained. No degradation of intensity (radiance) information occurred in implementing the geometric correction.
