Публікація Bank Lending Efficiency in the Real Sector of the Economy of Ukraine within the Period of 2011 to 2014 Years(Scientific Research Publishing, 2015) Mohammad, A.; Kots, G.; Lyashenko, V.According to the classical theory of banking development and traditional idea of practical matters of bank management, lending is one of the main directions in banking. It is connected with that realization of credit transactions should be considered as a defining component of bank management. According to this defining component each separate bank will organize loan of resources and their subsequent arrangement on proper conditions and on proper risk. Hence, taking into account the retrospective review, the work analyzes the fluctuations of rating values of the bank lending efficiency in the real sector of the economy. The analysis is carried out on the example of the banks of Ukraine within the period of 2011 to 2014 years. For the purpose of examining the values of bank lending efficiency in the real sector of Ukraine’s economy, the article considers the efficiency stochastic boundary model. There were analyzed in detail the forms of distribution by particular efficiency value levels of bank lending in the real sector of Ukraine’s economy, which were obtained for 16 different time dates from the interval analyzed. There was made the conclusion about necessity of balanced use of real resources of banks for growth of crediting efficiency.Публікація Common methodology of data analysis of natural disasters(GJESRM, 2016) Mohammad, A.; Kuzemin, A.; Lyashenko, V.; Tkachenko, B.Providing of safe human life is very connected with research and analysis of different disasters.

It is caused by that the significant part of information about outward things can be received on the basis of the video data analysis about images of the real world. At that, such analysis uses various methods, approaches and theories where the special place is occupied by the procedures connected with recognition of scenes or separate objects, presented on incoming images. Thus, it is necessary to consider the fact, that incoming images owing to objective factors could be subject to various geometrical distortions. Such distortions impose the restrictions and features on possibility of application of separate approaches and methods to processing and interpretation of images. Hence, a procedure of correlation normalization of images which allows to compare and recognize images is considered in this work. The work proves the possibility of representation of projective group of transformations, as one of versions of geometrical distortions of the incoming image, in the form of composition of the basic, simple transformations which are also versions of geometrical distortions of the incoming image. At the same time, the expediency of application of a partial correlation method for realization of procedure of correlation normalization of images is considered. The formalized description of the offered procedure of correlation normalization of images is given. Examples of separate steps of realization of the offered procedure are resulted.Публікація Methodology of Wavelets in Relativistic Heavy Ion Collisions in One Dimensional Phase Space (η-Space)(Scientific Research Publishing, 2017) Lyashenko, V.; Mohammad, A.; Deineko, Z.; Hashim, R.An attempt has been made to apply the wavelet methodology for the study of the results of the chaotic behavior of multiparticle production in relativistic heavy ion collisions.

The analysis is carried out on the example of the banks of Ukraine within the period from 2009 to 2012 years. For the purpose of examining the values of banklending efficiency in the real sector of Ukraine’s economy, the article considers the efficiency stochastic boundary model, which uses the intermediary function for bank functioning description based on the asset approach. This methodology allows us to investigate the complex processes of bank lending. There were analyzed in detail the forms of distribution by particular efficiency value levels of bank-lending in the real sector of Ukraine’s economy, which were obtained for 16 different time dates from the interval analyzed. As the result of the analysis, the article reveals the tendency to decline in average values of bank-lending efficiency in the real sector of Ukraine’s economy, which is observed against the background of considerable values of inefficient component quota in error full dispersion of the observed model of the corresponding stochastic efficiency boundary. At the same time it is shown that the efficiency of processes of transformation of attracted resources into lending resources with relation to banks functioning in Ukraine is determined in many respects by the adequacy of the real banks resources usage.Публікація Study of Composite Materials for the Engineering using Wavelet Analysis and Image Processing Technology(TJPRC, 2017) Lyashenko, V.; Mohammad, A.; Kobylin, O.; Khan, A.Wavelet analysis and image processing technologies are important Tools for data analysis.
