Документ Information technologies of decision support in transboundary emergencies(2018) Cherednichenko, Olga; Tkachenko, V. V.The transboundary character of any emergency leads to the additional challenges, namely, the absence of the direct access to center of accident and possible difficulties in the relationship with the authorities of the neighboring territory. The given work represents the information technology that allows to deploy the emergency infrastructure in the shortest terms, collect and process environmental data from different data sources and transfer it to the decision support system in a real-time mode, thus, improving the efficiency of decision-making process.Документ Parametric vibration of multilayer plates of complex shape(Springer US, 2014) Kurpa, Lidiya; Mazur, O. S.; Tkachenko, V. V.We propose a numerical-analytic method for the investigation of parametric vibrations of the plates under the action of static and periodic loads applied in the middle plane. The method is used for the equations of motion of plates obtained within the framework of the classical theory. The developed approach is based on the application of the theory of R -functions and variational methods, which enables us to study plates of arbitrary geometric shapes with various boundary conditions. According to the proposed approach, we first find the subcritical state of the plate if it is not homogeneous. To construct the zones of dynamic instability, we use the method proposed by Bolotin. The results obtained with the help of the developed approach are compared with the available data. We solve a number of new problems for multilayer plates of complex geometric shapes with holes.Документ Vibration and buckling of laminated plates of complex form under in-plane uniform and non-uniform loading(Politechnika Łódzka, 2019) Kurpa, Lidiya; Tkachenko, V.
