Effect of salt concentration on osmotic potential in drying soils—Measurement and models
European Journal of Soil Science, Volume 75, Issue 5, September–October 2024.Abstract The water potential in drying soils, comprising both matric potential and osmotic potential components, can be measured using the dew point method (DPM). By combining DPM data with retention curve data acquired from techniques such as the suction plate method or the simplified evaporation method (SEM), it becomes possible to determine the soil

Raim – A model for iodine behavior in containment under severe accident condition
Nuclear Engineering and Technology, 2015 Following a severe accident in a nuclear power plant, iodine is a major contributor to the potential health risks for the public. Because the amount of iodine released largely depends on its volatility, iodine's behavior in containment has been ...

Extending RAIM with a Gaussian Mixture of Opportunistic Information
The International Technical Meeting of the The Institute of NavigationGNSS are indispensable for various applications, but they are vulnerable to spoofing attacks. The original receiver autonomous integrity monitoring (RAIM) was not designed for securing GNSS. In this context, RAIM was extended with wireless signals, termed signals of opportunity (SOPs), or onboard sensors, typically assumed benign.
