: Conducting laboratory and field testing is a classic approach to the development and certification of vehicles and their automotive components. These processes are costly and time-consuming. The serial installation of mechatronic systems in the car forced software and electronic systems engineers to master a new approach to testing and development - "physical" simulation (Hardware-in-the-loop). The aim of the research in this article is to develop, implement and validate a “physical” simulation method for evaluating the performance of Electronic Stability Control (ESC) systems. In this research, an ESC HIL-testbench, a mathematical model of the vehicle curvilinear movement in Adams Car, and a method for converting it into a Simulink-model, that allows generating a C-code, were developed and implemented. To assess the adequacy and correctness of the “physical” simulation, full -scale dynamic manoeuvres were carried out on the object of research - the Gazelle Next vehicle with ESC-system “ Bosch ESP 9.1 ” . In this article, the results of road tests and simulations, as well as an assessment of their convergence, are presented in tabular and graphical forms. The maximum discrepancy was 19% with the maximum allowable one up to 25% in accordance with the standard ISO 19635.

: The handheld polishing machine plays a pivotal role in enhancing the aesthetics of household products, making it a vital device. This research aims to identify the optimal option among the available types. Thirteen diverse handheld polishing machines were utilized for evaluation. Six key criteria were carefully chosen to assess each alternative, encompassing price, capacity, polishing disc diameter, polishing disc speed at idle, machine weight, and supplier warranty period. The relative importance of these criteria was determined using four distinct methods: Equal weighting, RS ( Rank Sum ) weighting, ROC ( Rank Order Centroid ) weighting, and Entropy weighting. The MARCOS ( Measurement Alternatives and Ranking according to COmpromise Solution ) method was employed to rank the alternatives. Remarkably, all four different weighting methods consistently led to the same conclusion, identifying the best and worst options.

: The purpose of this work is to prove the effectiveness of a practical study of the temperature regime for diagnosing bearing assemblies of mechanical transmissions. Using the example of a two-row roller bearing of the rear support of the intermediate shaft of the vehicle transmission, the temperature in the friction zone under different transmission operating modes on a KAMAZ-5320 was calculated. Finite element analysis of temperature fields made it possible to determine the relationship between the temperature on the outer surface of the bearing assembly and the temperature in the friction zone through the coefficient k=0.327. The zone for temperature measurement - the bearing cover is determined and the maximum temperature of its heating is set. Thermal imaging observations confirmed the effectiveness of the developed method of technical diagnostics of bearings.

: Exponential progress in integrated circuits, best described by Moore's Law, has enabled tremendous advances in applied computing. Today, more than ever, there are palm-sized embedded devices with computational capabilities millions of times greater than those of what was once the lead computer on the Apollo 11 mission. Such levels of integration enable the fusion of functionalities that were once unimaginable, or at least impractical. Furthermore, today's existing technologies rely mostly on one or two communication technologies to organize UAVs for efficient search and rescue missions that largely do not utilize the communication convergence principle, thus omitting the potential for better search yield and rescue success. This paper recognizes that niche where communication convergence lacks its potential and presents a concept for the convergence of Wi-Fi, Bluetooth, LoRa and/or satellite IoT communication technologies to serve as an airborne communication infrastructure, a backbone generally, and enables a swarm of unmanned aerial vehicles (UAV) to communicate efficiently wherever there is no local terrestrial communication infrastructure (such as GSM, Wi-Fi, digital radio, etc.). The concept was elaborated and applied to a use-case localization application scenario (of Wi-Fi enabled devices) for the purpose of search during rescue operations.

: This paper focuses on modeling the tribological properties of AZ31-SiC composite using an artificial neural network (ANN) fabricated through the stir casting method. The twenty-seven tests were performed with three loads (10 N, 15 N, and 20 N), three sliding speeds (0.5 m/s, 1.0 m/s, and 1.5 m/s), and three sliding distances (500 m, 750 m, and 1000 m) on wear testing machine and are used in the formation of training sets of ANN. Using the wear test data, Taguchi, Analysis of Variance (ANOVA), and regression analysis were carried out to determine the effect of the control parameters on the wear and coefficient of friction (COF). The experimental results demonstrate that the wear rate increases with an increase in load and distance and decreases with an increase in velocity. In addition, an alternative method is proposed to predict the wear and COF using ANN modeling with single and multi-hidden layer techniques. With good training, ANN gives accurate and close results to the experimental results. The results obtained using ANN modeling have a percentage of error of 4.71% and 5.79% for wear and COF respectively, when compared to experimental values. This prediction process saves time and costs for the manufacturer.

: Lean manufacturing is a corporate strategy that focuses on continually improving all processes in the production environment by reducing waste and costs. The implementation of lean manufacturing systems will always begin within the existing facility layout. Therefore, the arrangement of the facility has a tremendous impact on the company’s development and space utilization. This research addresses possible research gaps related to the industry's requirement for successful lean manufacturing and space utilization. In this research, an integration of lean techniques and facility layout planning has been used to optimize the workshop operation by implementing 5S and Systematic Layout Planning to rearrange machines, which eliminated waste caused by unnecessary motion. As a result, out of two alternatives of facility layout proposed, the process efficiency is improved from 53% to 66%. An efficient facility layout helps production schedules run more smoothly while minimizing costs and enhancing space utilization. It has contributed to create a safe and healthy work environment. The research is limited to optimizing space utilization and attempts to eliminate excessive motion of employees and equipment in the machining shop of a mechanical workshop. The need to close the implementation gap for lean and space utilization will make a substantial contribution to long-term industrial sustainability.
