A Colour Image Watermarking Technique Resistant To Affine Geometric Attacks
(University of Nairobi, 2013-09)
This paper presents a colour image watermarking scheme resistant to affine geometric distortions. The technique involves embedding of the watermark in the host image in the Discrete Cosine Transform (DCT) domain in a ...
Distribution of glycerol diakyl glycerol tetraethers in surface soil and crater lake sediments from mount Kenya, East Africa
(University of Nairobi, 2013-12-13)
Glycerol diakyl glycerol tetraethers (GDGTs), a palaeoclimate proxy based on the relative abundance of lipids produced by archaea and bacteria, is gaining wide acceptance for the determination of past temperature and pH ...
What was the source of magnetic field measured by pioneer V in 1960
(University of Nairobi, 2013-11)
The engulfment of Pioneer V with solar plasma on March 30, 1960, and the later measurement of high interplanetary magnetic field (IMF) by the probe were interpreted as of solar origin. Studies and analysis of that event ...
