Automated flood water control system
The lower level of the flood water control system will allow to normalize the analogue signals from the sensors (water level, amount of atmospheric precipitations and soil moisture) for further analysis and represented by four functions, namely: FC1 - the function of normalization of analog signals FC2 - the function of comparison of current values...

Evaluation of the symbiosis between Rubus fruticosus and mycorrhizal fungi on the Bozanta Mare tailings pond in view of their use in ecological remediation
Waste resulting from mining activity is today one of the biggest environmental problems. The mine deposit on the Bozanta Mare site, due to the high content of heavy metals (Pb, Cu, Cd, Zn, Cr, Ni), is a difficult substrate for the installation of a vegetal carpet. Naturally, a small number of species have been installed on the soil with a high conc...

Component-oriented modelling of dynamical systems in Python language on the example of the model of the sucker rod string
The principles of component-oriented hybrid modelling of complex dynamical systems based on the Python language and its SymPy and SciPy libraries have been proposed. The Python-classes that allow you to create the models in Python without the need to study and apply specialized modelling languages have been developed. These classes can also be used...
