To date, one of the important and urgent tasks of the science of electrodynamics is to study the scattering characteristics of various complex electrodynamic objects. Among them, hollow structures can be distinguished, which are part of antenna systems and structures of various technical facilities. Their contribution to the levels of electromagnetic fields in the anterior hemisphere can be quite large. The correct solution to the problem of scattering of electromagnetic wave scattering characteristics is associated with the use of appropriate methods. The paper considers the solution of the problem based on the method of integral equations. During the analysis of the two-frequency effect, the use of the wavelet transform is considered.

In this article, we analyze the operation of the road network of the city of Karbala in Iraq, which is characterized by its religious and tourist character, and evaluate the effectiveness of the urban street network in it in order to identify the main steps that need to be taken to take measures to improve traffic efficiency and reduce delays. The scientific novelty of this work lies in the fact that it is the first of its kind, as far as we know, which addresses the problem of traffic efficiency in the city of Karbala as a whole, since the traffic density on the main transport axes in this city varies greatly during normal times and peak hours (morning and evening). The results of the analysis showed that some sectors operate in conditions of congested (stable) traffic (LOS F) in the morning and evening hours, and such sectors require immediate traffic management strategies. While the rest of the sectors are operating at or close to the same capacity (LOSE).

Purpose - Analyzed the operation of the Karbala city road network in Iraq and evaluate its effectiveness to identify the main steps that need to be taken to improve traffic efficiency and reduce delays.

Methodology. In this work, an experimental analytical methodology was used, in which data were collected, analyzed and compared with relevant information sources.

Results. The categories of urban roads were determined based on the speed of free movement (FFS), and the level of service (LOS) is calculated for selected urban streets taking into account the average speed of traffic (ATS). Measurements of speed and travel time showed that traffic jams occurred on Fatima Al-Zahra Street, the second part of Ramadan Street and some sections of Al-Abbas Street in the morning. These areas require immediate traffic management strategies. In the evening, traffic jams were also observed on sections of Fatima Al-Zahra Street, part 2 of Al-Iskan Street and the first section of Ramadan Street. The decrease in traffic speed led to traffic jams on Al-Abbas, Al-Iskan Streets and some sections of Fatima Al-Zahra Street. Low FPS values indicate that the average speed of movement in these areas is low even with a small flow.

Practical implications. It is recommended to apply the results obtained to the Traffic Management Department of the city of Karbala.

Background. The topic of the article is timely. Many interesting and technically quite feasible ideas in equipping the stage were not implemented in the theater due to the lack of direct groundwork and limited time resources.

Problem statement. Generalization of the latest experience in the field of theatrical machinery requires raising the issue to the level of an interdisciplinary scientific direction based on mechanics, mechatronics and robotics.

Purpose. The need to implement the increasingly complex ideas of performance directors in a modern theater requires the improvement of demonstration equipment, primarily theatrical machinery based on new scientific achievements and modern technical means of mechanization and automation.

Research methods. Special stage robots can have a very different appearance, for example, they can be zoomorphic or anthropomorphic, but while maintaining the style of constructivism, they can have a man-made appearance. Such robots can perform complex movements, while they usually have numerous moving parts with independent drives. To provide flexible motion control capabilities with a focus on spectator perception, it is required to use microprocessor control with coordination from central control computers.

Results. When setting requirements for such a technique, the orientation towards visual perception is specific, which is also used in demonstration robotics. Based on the scientific generalization of previous and new experience in creating technical equipment for theatrical productions of large theaters, the paper describes and characterizes typical tasks of creating and working out a scientific base for creating modern and promising equipment for theatrical productions based on general principles and practical methods of mechanics, mechatronics and robotics.

The article deals with the relevance of using composite materials of biological and synthetic origin in the elements of passive and active safety of the car. The topic of road safety is still topical, as cars are becoming more and more every year. The safety characteristics of vehicles should improve and environmental pollution should be reduced. To achieve these goals, various approaches of using composite materials in car body elements have been proposed. In addition to safety features, composite materials also reduce the weight of the vehicle. Such a vehicle picks up speed faster and consumes less fuel, reducing environmental pollution. Using the example of a Porsche car, parts made entirely and with carbon fiber are examined. A summary of the further use of the technology in the country and the world is given.

Scope of application of the results. The results can be used in the design and development of passive and active safety elements.

One of the important sectors in the economy is the metallurgical industry, which supplies raw materials and semi-finished products to other strategically important industries. The issue of quality control in this area is very relevant. Since the quality of the metal depends on the quality of subsequent products, products that must withstand all prescribed loads and regulations, as well as ensure safe operation for many years. Accordingly, all products of the metallurgical industry are subject to mandatory certification. The quality certificate is an official document and confirms the declared characteristics of the metal. All information from the quality certificate should be recorded in the information system in such a way that it is possible to track each specific batch of metal with the characteristics declared according to the certificate from purchase to release of finished products. The article discusses new possibilities of using web services for the exchange of information on quality certificates between contractors with various information systems. The essence of this innovative method is that the metal supplier transmits the data according to the quality certificate together with the electronic printed form, and the buyer accepts this data and writes it to the integration bus using web services for subsequent transmission to the necessary information systems. Thus, the risk of errors that are present during manual input will be eliminated, the time for entering and processing information will be reduced to ensure the full operation of technical control in the organization.

Purpose. Optimization of the process of material and technical support by metal rolling for enterprises of the machine-building industry.

Methodology: the article used survey, analysis, comparison, modeling.

Results: a new method of transmitting information on quality certificates using web services, which allows you to avoid errors during manual entry, as well as optimize the registration process of admission.

Practical implications it is advisable to apply the obtained results for enterprises of the machine-building industry engaged in the purchase of rolled metal.

The purpose of the study was to improve the remuneration system for operators of automatic lines, machines and plants by using the labor participation rate, which will allow making optimal management decisions on accounting for payroll settlements with staff and the achieving of strategic goals of the organization.
