The exploitation of traces in JPEG double compressed images is utter importance for investigations. Properly exploiting such insights, First Quantization Estimation (FQE) could be performed order to obtain source camera model identification (CMI) and therefore reconstruct the history a digital image. In this paper, method able estimate first quantization factors presented, employing mixed stati...

BACKGROUND & AIM While most of the published researches have reported the amount of inequity in geographical distribution of important health resources, only a small number of studies have focused on the trend of inequality in the distribution of these resources. The purpose of this study was to determine the trend of inequality in the distribution of intensive care beds in Iran during 2010 to ...

Abstract Correlations play a significant role in data analysis and the evaluation expression of uncertainty, yet estimating them is often difficult. This paper provides examples how to infer measurand value, given only uncertainties correlation ranges measurement results. The least informative data-distribution not Gaussian, but marginal distributions are. Explicit results are case pair, where ...

Lidars have been employed in the investigation of instantaneous vertical structure of atmospheric particulate. Remote measurements of particle backscattering and aerosol extinction coefficient provide the altitude distribution of particles existence in the atmosphere. This paper describes the technology of micro pulse lidar employed for computation of altitude profiles of particle backscatterin...
