A RADIOMETER FOR METEOROLOGICAL MEASUREMENTS WITH ACCURATE CALIBRATION BY THE SKY BRIGHTNESS TEMPERATURE [PDF]
Радиофизика и электроника, 2016 Methods for passive sensing the atmosphere in the microwave range are one of important directions of remote sensing of environmental protection. To develop simple and cost-effective technical solutions and radiometric measuring techniques is an important

Intrinsic Brightness Temperatures of AGN Jets
The Astrophysical Journal, 2006 We present a new method for studying the intrinsic brightness temperatures of the parsec-scale jet cores of Active Galactic Nuclei (AGN). Our method uses observed superluminal motions and observed brightness temperatures for a large sample of AGN to constrain the characteristic intrinsic brightness temperature of the sample as a whole. To study changes

Temperature and Brightness Variations on Betelgeuse [PDF]
Symposium - International Astronomical Union, 1986 Changes in Ti0 band strengths correlate well with the brightness changes of α Orionis, thus supporting the hypothesis of Schwarzschild that the irregular luminosity variations of red giants are due to temperature changes in a few extremely large convective elements on their surface.

Homogeneous vs Biased IGM: Impact on Reionization
Frontiers in Astronomy and Space Sciences, 2021 This paper considers the impact of large scale biasing of the IGM on reionization. The two simplest but extreme scenarios for IGM biasing are: an unbiased IGM which has a constant density and an IGM with density equal to the collapsed matter density.

Colour of baked products during baking
Czech Journal of Food Sciences, 2000 The parameters of the colour of the surface of bakery products - brightness L*, a* for red and b* for yellow colour - were measured at different temperature regimes. The parameters were found to change during the time of baking.
