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.

Wave field simulation using finite element method on the Drobyshivske gas-condensate field structure

The results of seismic wave field modeling on the cross-section model of the crust (for Drobyshivske gascondensate field example) were presented. The cut of the crust which resulting the boreholes geophysical studies is 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.
 

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.

Using genetic algorithms for modelling informational processes

In this article genetic algorithms are considered including their types and practical applications. The scientific works of domestic and foreign researchers have been studied. This article presents methods and examples of solving tasks of data mining for genetic algorithms. The description of main components of models of genetic algorithms is presented. A parallel between biological systems and systems aimed at solving technical problems is drawn.

Calculation of the dynamic response of reinforced concrete structures subjected to the ffects of heavy transport

A 3D model of a reinforced concrete building was created using a dynamic analysis which focused on the spectral response of the object represented by a random excitation experiment found in records in the form of load spectra.

Типи лінгвістичних моделей та їх застосування для розв’язання лінгвістичних задач

This paper outlines understanding of the notions ‘model’ and ‘modeling’ in linguistics. The main linguistic models and their application to solving different linguistic tasks are described.

Методи та інструменти моделювання інформаційних процесів

In the article the theoretical principles, methodological and practical recommendations to enhance the effectiveness of the information system were proposed. The analysis of the basic principles and methods of modeling of information processes and methodology of forming an information system are justified. A systematic approach that allows to consider general strategic objectives of association and to form patterns and limits for receipt and interpretation of decision support systems was formulated.
