Automated preparation of water samples for low-level gamma spectrometry

Acta Chimica Slovenica, 2016
The analysis of water samples using gamma spectrometry requires the preconcentration of the sample in order to determine the content of low-level radionuclides. An automated evaporator was used for this purpose during the preparation of approximately 250

Bayesian inference for inverse problems [PDF]

, 2001
Traditionally, the MaxEnt workshops start by a tutorial day. This paper summarizes my talk during 2001'th workshop at John Hopkins University. The main idea in this talk is to show how the Bayesian inference can naturally give us all the necessary tools ...
