## Improved calculation and strength of thermowells during operation

Accurate evaluation of possible safe operation of thermowells essentially depends on the accuracy of the maximum stresses in them during operation. These stresses are generally determined from simple engineering formulas for bulk of canonical shape, mostly cylindrical shells or beams for the relevant boundary conditions. Thus the general solution is obtained step by step. First the tangential stresses are obtained from relations for cylinder subjected to external pressure.

## Mathematical apparatus for prediction of anomalous inflows (tsunami)

The paper contains the description of the feasible approach to modeling of environmental processes, namely abnormal tidal (tsunami). The suggested mathematical apparatus is based on the statistical methods and comprises hidden Markov models, linguistic modeling and similar trajectories method.

## Wave field simulation on the gas-condensate field structure

The results of seismic wave field modeling on the cross-section model of the crust (for Drobyshivske gas-condensate field example) were presented. Complicated cut of the crust, resulting geophysical study, represented as a reservoir model. When modeling, seismic wave field features of two-dimensional cross section were taken into account: longitudinal, transverse and exchange waves received on seismograms of longitudinal and transverse vibrations as a result of default distribution of velocities of longitudinal, transverse waves and the density in half-space medium.

## The formulation and development of methods of solving thermomechanics problems for irradiated layered solids

A mathematical model to describe a thermoelastic state of plane-parallel plates (plate composites) subjected to a thermal radiation is developed. The model is grounded on phenomenological theory of radiation and quasistatic thermoelasticity. It takes into account an effect of radiation on plate surfaces, contact boundaries, and in in semi-transparent areas.
