The article investigates how to organize cross-functional e-commerce teams by integrating DevOps and traditional project management (PM) processes with systems engineering and quality assurance practices. Drawing on empirical data, classic Waterfall, Agile, and DevOps models, and a review of advanced techniques, it proposes a unified team structure comprising a Product Owner, Business Analyst, UX/UI Designer, Tech Lead, Developers, QA Specialists, and Systems Analysts. It demonstrates how Agile workflows and CI/CD pipelines align with PMBOK-based PM processes, how incremental system architecture and requirements traceability ensure precise tracking from conception to deployment, and how automated testing and DevSecOps practices balance release speed with platform reliability. Tables detail role distribution and a DevOps–PM alignment matrix, clearly illustrating which DevOps activities correspond to each PMBOK process group. These findings offer a methodological foundation for building high-performance e-commerce teams that accelerate time-to-market without sacrificing quality or scalability, and will be of interest to researchers of organizational behavior and sociotechnical systems, as well as to DevOps and project managers focused on optimizing continuous integration, delivery, and product management.

The development of a computational model of an induction motor with ring windings (IMRWs) for processing of nuclear waste is considered. At the first stage of the work, the overload capacity of the computational model of an IMRW was analyzed using the finite element method, the calculation being carried out in stages, taking into account the production and physical features of the IMRW prototype design. The IMRW model takes into account the influence of the oxide film on stator core sheets, technological gaps, eddy currents, and temperature conditions of the stator and rotor windings on the overload capacity of the IMRW. At the second stage, the mechanical characteristics of the IMRW were analytically calculated in the Ansys program using the parameters of the equivalent circuit determined by analyzing the design model of the motor. The calculated mechanical characteristics of an IMRW obtained by the finite element method and analytical calculation are compared with the results of testing the prototype.

The analysis of a diesel locomotive induction motor electric drive operation in a limited voltage and current region is made. A method of an induction motor rotor flux linkage forming when operating in a voltage and current limiting regions is proposed. Described method allows controlling an induction motor electric drive more efficiently by using refined equation for the flux-forming component of the stator current. A comparative analysis of the traction induction motor electric drive modeling with different methods of the rotor flux linkage forming is given.

Possibilities of improving the dynamic characteristics of brushless excitation systems are considered. A technique for choosing the value of the additional resistance in the excitation winding of a reverse synchronous generator, the gain of the hard negative feedback and the excitation-forcing ratio of the exciter by voltage has been developed. The reasons for the appearance of high-frequency pulsations in the excitation voltage of a reverse synchronous generator are considered. The technique was applied when choosing the means of improving the dynamic characteristics of the BVD-4600-1500 brushless exciter, operating with the TVV-1000 – 4 generator.

A comparative analysis of the electromechanical characteristics of induction traction motors with different cooling systems and different rotor cage materials has been performed. For ease of comparison, all alternatives are designed in such a way that the temperature rise of the stator winding is approximately the same. Particular criteria are proposed, including economic indicators that form the functional for finding the most effective solution. According to the best design variant of the motor, a pilot industrial model of the motor for a light rail vehicle was manufactured.

Methods of modernizing the regulation systems of electric machinery exciters with high-frequency, brush-free, and collector exciters by means of microprocessor technology are examined. The main problems of modernization are to increase the response speed of a system and to use a system stabilizer to increase the stability of the power system.

Conductors in pulsed magnets in the U.S. National High Magnetic Field Laboratory (MagLab) are rectangular cross section wires of relatively large thickness. During the manufacture of the magnets, some of these conductors are wound to small-diameter coils (less than 15 mm). Because of the large thickness and the small bending radii for winding, the wires undergo large bending strain, sometimes causing breakage. We studied the bending behavior of high-strength conductor wires. In most materials, maximum bending strain can usually be calculated from elongation values obtained in tensile tests. In this paper, however, the maximum bending strain exceeded the elongation of most of our high-strength wires; therefore, we could not estimate bending strain from elongation. The large bending strain that occurs during the manufacture of coils in pulsed magnets causes an increase in residual strain and a decrease in packing factor. Due to the anticlastic effect, the cross section of the wire changes from rectangular to keystone-shaped, with the keystone angle up to 10 <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$^{\circ}$</tex-math></inline-formula> . This introduces gaps into the coils, thus reducing the magnetic field by an amount that must be taken into an account. In both tensile- and compressive-strained regions, we observed significant microstructure changes. Certain properties, such as tensile mechanical strength and electrical conductivity, depend directly on microstructure. This paper summarizes our work on both geometry and microstructure evolution in conductors exposed to different bending strain values.

The anomalous increase of the mechanical strength in copper matrix FCC-BCC composite materials caused by the specific nanoscaled microstructure formed by the heavy plastic deformation is associated mainly with the nature of the interface boundary areas. The differences in the nature of the interface areas in the Cu-Nb, Cu-V, and Cu-Fe have been discussed in connection with the parameters of crystallographic structure of three BCC elements (Nb, V, Fe). The nanostructured Cu-Nb, Cu-V, and Cu-Fe experimental high strength, high conductivity wires have been fabricated by the similar technological routes. The tensile strength and electrical conductivity for Cu-Nb, Cu-V, and Cu-Fe microcomposite wires are presented. The stability of the filamentary nanoscaled microstructure created by the large plastic deformation is investigated. We demonstrate that it is possible to maintain mechanical strength higher than 400 MPa after long time heat treatment between 250°C and 400°C.

The work considers technical requirements for traction motors and motor-generators and optimization of active parts of asynchronous traction motors under the "torque/mass" and "torque/losses" criteria, and analyzes the influence of dimensions and other parameters of motor active parts on motor specifications, along with the issues of coordinating the characteristics of traction motors with those of power converters. Prototypes of asynchronous traction motors with optimized geometry of active parts are presented, as well as their use in the vehicles, designed by the RUSELPROM Concern.
