Defects of communication pipes from plastic in modern civil engineering
(TJPRC Pvt. Ltd., 2018) Lyashenko, V.; Ahmad, M. Ayaz; Sotnik, S.; Deineko, Z.; Khan, Alveera
Plastic is an important material that is used in civil engineering. Communication pipes - one of the directions of use of plastic. The external environment affects the quality of the use of plastic pipes. Therefore it is important to know the defects of plastic products. It is also necessary to make assessment of the quality of the use of plastic pipes. It depends on many factors. Therefore the task of detection and preventing of the communication pipes defects - the complex task. We did a survey of the major defects of the communication pipe. We have examined the factors that influence the formation of defects in the communication pipe. A classification of variable factors that affect the quality of communication pipes is proposed. A generalized algorithm for evaluating the quality of communication pipes has also been developed.

(Scik, 2021) Nevliudov, I.; Yevsieiev, V.; Baker, Jalal Hasan; Ahmad, M. Ayaz; Lyashenko, V.
This paper considers the issues of software development automation for cyber-physical production systems within the framework of the Smart Manufacturing (SM) and Industry 4.0 concepts. The development of cyber-physical production systems (CPPS) for each enterprise is an individual task that takes into account the specifics of the production process, the requirements for data visualization at each level from Supervisory Control And Data Acquisition (SCADA) to Enterprise Resource Planning System (ERP) in a single information space using different technologies for processing and storing data. To ensure all the requirements that are specified by the customer in the technical requirement (TR), the authors propose to automate the process of developing a cyberphysical production systems Human-Machine Interface (HMI) prototype at an early stage of drafting the terms of reference together with the customer, which will make it possible to take into account all the requirements for visualizations information. Based on the experience gained in the development of cyber-physical production systems, the authors have developed a declarative cyber-design modeling language based on parameters mathematical description of the and Graphical User Interface (GUI) elements events, which allows to simplify the process of HMI cyber-physical production systems development at an early stage by generating fragments of program code for object-oriented programming languages.
General Methodology for Implementation of Image Normalization Procedure Using its Wavelet Transform
(IJSR, 2014) Lyashenko, V.; Kobylin, O.; Ahmad, M. Ayaz
Image processing is one of the fundamentals of various intelligence systems based on data analysis. In addition among the variety of different methods and approaches to image processing, image normalization methodology can be pointed out. The essence of such image processing methodology is in compensating various geometrical distortions of input image that was obtained through registering test image and forwarding it to the data mining system, in comparison with some reference (master) image. In such case, there arises a problem of time reduction for normalization procedure for some image processing systems. It is suggested that this task can be solved through the use of levels of wavelet decomposition of input image and conducting normalization procedure on separate levels. To solve this problem, this articles studies special aspects of wavelet decomposition of the image into separate levels of decomposition, functionality types of basic groups of image normalization by taking into account the use of wavelet decomposition levels of the test image, general methodology for determining transformation groups for image normalization based on wavelet decomposition. The fairness of the considered methodology is supported by the number of experiments.

Interactive Geoinformation Three-Dimensional Model of a Landscape Park Using Geoinformatics Tools
(IJASEIT, 2020) Ahmad, M. Ayaz; Tvoroshenko, I.; Baker, Jalal Hasan; Kochura, L.; Lyashenko, V.
The relevance of work is due to the lack of free three-dimensional models of landscape parks and the urgent need to create such models for informing and barrier-free adaptation of users. The current state of cartographic support of landscape parks is low and does not meet users, management, and employees of parks. The object of research is the territory of the multicomplex. The purpose of the research is to develop a three-dimensional model of the regional landscape park for informing and barrier-free adaptation of residents and guests of the city using geoinformatics tools. The methods used in this research are general scientific (system analysis, modeling, higher mathematics) and special methods of mathematical and geoinformation analysis. The work uses the ArcGIS and SketchUp software platforms to create, manage, integrate, analyze, and distribute spatial data. Methods used: geodesy, topography, geoinformatics. The results obtained in the course of the work are of practical importance, are real and tested by the management of the regional landscape park. An interactive three-dimensional geoinformation model implemented in the ArcScene software environment will provide an opportunity further to manage the territory of the regional landscape park. An interactive geoinformation three-dimensional model ensured a 12% increase in the level of informational and barrier-free adaptation of residents and guests on the territory of the multicomplex. The prospects for further research on the creation of a mobile application for park visitors with the ability to search for the nearest bus departure point at their location are determined.

Modern Walking Robots: A Brief Overview
(IA-ESTE, 2021) Lyashenko, V.; Ahmad, M. Ayaz; Belova, N.; Sotnik, S.
In this review, we would like to present some of the most interesting modern designs of walking robots: bipedal, quadropedal, hexopedal, and octopods. Their advantages and disadvantages are highlighted. It has been determined that structures with eight or more limbs are ineffective due to high level of electricity consumption. The use of more than six number of legs does not give noticeable advantages in profile cross-country ability or maneuverability, however, it allows to reduce the forces and moments of inertia forces due to decrease in mode coefficient (ratio of time spent by propulsor in support to time of entire step), and, consequently, smoother leg movements in swing phase.

Some Effect of Chemical Treatment by Ferric Nitrate Salts on the Structure and Morphology of Coir Fibre Composites
(Scientific Research Publishing, 2015) Khan, Alveera; Joshi, Shirish; Ahmad, M. Ayaz; Lyashenko, V.
The present study shows some important effects of chemical treatment on the structure and morphology of coir fibre. The objective of the present study is to optimise overall properties of coir fibre so as to use coir fibre as a reinforcing agent in thermoplastic and thermosetting polymers. In the present study, coir fibre is treated with ferric nitrate salt. A thermal treatment has been done at temperature of 1000˚C by using annealing method. X-ray diffraction of the treated coir fibre reveals the crystalline nature of the fibre. Change in morphology has been found in coir fibre when subjected to scanning electron microscopy. Finally, the Fourier transform and infrared spectrographs show the presence of traces of iron oxide:fibre in the prepared composite.
Some evidences of multiplicity fluctuations in relativistic nuclear collisions and Neural Networking (N-N) model
(Academia Publishing, 2020) Ahmad, M. Ayaz; Victoria, Anghel Drugarin C.; Baker, Jalal H.; Lyashenko, V.
This study attempted to investigate some features of non-thermal phase transitions during the relativistic heavy ion collisions. The collisions that occurred were a beam of 28Si (projectile) hits the heterogeneous mixture of nuclear emulsion (fixed target) @ energy 14.6A GeV and we recorded 951 events of relativistic nuclear collisions. Thereafter, for the final statistical study, we made three different groups of data sets such as 28Si+CNO, 28Si+Emulsion and 28Si+AgBr. The results of the experiment was compared with neural network (N-N) model and a good agreement found between the theory and experiment of relativistic heavy ion collisions.
