    Field experiments and modelling show that the use of free-surface multiples can significantly improve the coverage of the vertical seismic profiling with downhole distributed acoustic sensors. Field studies also show that these sensors can record natural noise and human activity, and indicate imperfections of borehole cementation. The signal recorded by these sensors shows excellent correlation with reservoir pressure and temperature, which can be used for monitoring of CO2 injection into geological formations

    In a bounded domain with infinitely increasing quantity of infinitesimal holes whose asymptotic behaviour is described formally, the homogeneous Dirichlet problem for the equation with additional power nonlinearity on the time derivative of the solution is averaged

    The authors of the article have analyzed scientific research on the problem of the formation of cognitive readiness for educational activity in children with autism spectrum disorders of senior preschool age. It is noted that for children with autism spectrum disorders, a special approach should be applied with a focus on world standards and effective methods of correction and training should be developed. It is revealed that today the psychological and pedagogical correction of the development of autism does not have unambiguity and consistency regarding technologies and methods that would help to effectively overcome autism spectrum disorders and contribute to the effective preparation of autistic children for educational activities. The content of the concept of "cognitive readiness" is revealed as a prerequisite for the development of psychological characteristics and preparation of a child with autism spectrum disorders of senior preschool age for learning activities. The features of the use of correctional technologies to increase the level of cognitive readiness for educational activity of children with autism spectrum disorders of senior preschool age have been determined. It was revealed that the main condition for the formation of cognitive readiness for educational activity in children with autism spectrum disorders of senior preschool age is the use of ABA therapy technology, the TEACCH program, (PRT), PECS, sensory integration. It is revealed that the program (TEACCH, PECS) reflects a clear algorithm of actions, encourages mental operations; method (ABA-therapy) improves the stability of concentration, memory development, forms learning behavior; (PRT) promotes the development of motivation in a child with autism spectrum disorder of senior preschool age, self-management. The formation of imagination and perception of the surrounding world is carried out in the process of conducting classes with sensory integration. It is proved that the formation of cognitive readiness for educational activity in senior preschoolers with autism spectrum disorders is an important factor in the realization of personal potential and social adaptation

    The review of the existing approaches and algorithms for designing DSS based on fuzzy logic in case of changing the structure of the vector of the input data is considered in the paper. There was presented the own approach, which lies in correction (editing) the rules of fuzzy knowledge bases at different number of input coordinates of the system. Simulation results confirm the effectiveness and appropriateness of use of the algorithms of editing the rules of fuzzy knowledge bases in the process of DSS designing for management decision- making, particularly in solving problems of transport logistics
