Annotation: This paper proposes an approach for the analysis of data of geo- and hydrophysical monitoring for operational tsunami hazard assessment. Computational methods for estimating the parameters of earthquakes and recovering the form of tsunami source by mareogramms at the nearest DART stations were developed. Parallel version of the computational system for different types of parallel computing systems was implemented.

Annotation: The algorithmic scheme of use of the device of logical decision functions is developed for an assessment of danger of floods.

Annotation: This paper proposes acomputationalmethodto establishthe incidence ofregressiondependingon the factorsof the naturalandsocial environment onthe basisof neural network modelingof observational data. The neural networkmodels andnumerical experimentsfor a comparativeanalysis ofthe observational dataof diseasespecific groupswith a change inthe naturaland social environment are constructed.

Annotation: A method of modeling a dynamic process on the Earth surface, for instance, a forest fire, with the use of a recurrent neural network is proposed. The learning process of the neural network, similar to the process of data assimilation in GIS technologies is described. A method of acceleration of neural network learning by using the Kalman filtration is proposed. The efficiency of its application is analyzed. The software implementation of the model based on fire recurrent neural network which simulate the process in real time is presented.

Annotation: The simulation model of the command and measuring system of spacecraft onboard hardware is presented. The model contains tools for the graphical representation of all stages of tel-ecommand and telemetry packets transmission.
