The distribution of relative angles between the intermediate mass fragments has been measured and analyzed for thermal multifragmentation in p + Au collisions at 2.1, 3.6 and 8.1 GeV. The analysis ...has been done on an event by event basis. The multibody Coulomb trajectory calculations of all charged particles have been performed starting with the initial break-up conditions given by the combined model with the revised intranuclear cascade (INC) followed by the statistical multifragmentation model. The measured correlation function was compared with the calculated one to find the actual time scale of the intermediate mass fragment (IMF) emission. It found transition from sequential evaporation for p(2.1 GeV) + Au to simultaneous multibody decay of a hot and expanded nuclear system in case of p(8.1 GeV) + Au.
The method of steganographic embedding of information into thermal camera data is investigated. After evaluating the features of the noise component of thermal video data, it is proposed to use the ...stochastic modulation method, which consists in replacing the camera noise with noise having similar parameters and containing embedded information. To evaluate the embedding effectiveness, a number of parameters are examined, such as the volume of embedded information, compliance of the embedded noise with the original one, and resistance to steganalysis.
