This article addresses the challenges associated with subwoofer installation in vehicles with limited interior space, a pressing issue in car audio systems. Modern vehicles, especially compact models, often feature constrained dimensions, complicating the selection and installation of acoustic equipment. This study aims to analyze the issues related to subwoofer installation in vehicles with restricted space. Recommendations to improve the acoustic performance of such systems are proposed. The methodology includes a theoretical examination of existing methods for subwoofer installation in confined spaces.

The findings indicate that acoustic performance is influenced not only by the choice of subwoofer type and enclosure but also by the proper placement of the device within the vehicle. Installing a subwoofer in the trunk compartment, with appropriately adjusted enclosure parameters and amplifier settings, enhances the efficiency of low-frequency sound transmission. For vehicles with limited space, such as compact crossovers or hatchbacks, the placement of the subwoofer significantly impacts the overall cabin acoustics, along with the effects of noise and vibration. The choice of enclosure material plays a crucial role in determining resonance characteristics.

The information presented is valuable for engineers working with automotive audio systems and car enthusiasts interested in improving the sound quality of their vehicles. The results obtained can serve as a foundation for the development of new subwoofer models designed for use in restricted spaces.

This study investigates the influence of mold thickness on the cooling rate and hardness of gray cast iron in two distinct mold types: metal and sand molds. The experiment is conducted by casting gray cast iron in molds of varying thickness and measuring the cooling rate and hardness at different intervals during solidification. The results indicate that both mold type and thickness significantly affect the cooling rate and the hardness properties of the cast iron. Metal molds lead to faster cooling and higher hardness, while sand molds show slower cooling rates and lower hardness. This study provides insight into how mold design and thickness can optimize casting quality and material properties for industrial applications.

The aim of this study is to investigate the factors constituting the adoption of Fibre Reinforced Polymers (FRPs) in construction projects, performance characteristics, monetary effectiveness, sustainability, environmental plays, and an obstacle to adoption. Of all the various materials used, FRPs are noteworthy as being capable of uniquely high strength-to-weight ratio, corrosion resistance, and long-term durability, making them an excellent replacement for a traditional steel or concrete. While the advantages of using FRPs mentioned above should drive their adoption in construction, FRPs have not been widely adopted in construction because of high initial costs, shortage of skilled labour and lack of long-term performance data. Quantitative such as survey and statistical analysis are used in this research to determine the association as well as the effect to the adoption of adopting FRPs in construction.

Results indicate that the performance characteristics of FRPs, such as mechanical strength and corrosion resistance, are crucial in determining whether and how they are applied essentially because of their advantages of using in harsh environments. Furthermore, although less of such adoption is made for sustainability and environmental benefits, the adoption is even positively affected. In addition, while cost effectiveness was a well-established cost-saving associated with FRP; it did not have a strong bearing on adoption in this investigation. In the broader adoption though, there was a significant obstacle on the way, mainly the barriers to adoption, including the lack of skilled labour and regulatory constraints.

The study suggests a way to fight these previously mentioned barriers, through creating some standard guidelines, with government incentive, more trained people and display of FRP case studies of the long-term benefits. If the challenges are tackled and the structural construction projects developed in a more sustainable and a less cost manner, the full benefits of FRPs can be captured by the construction industry.

This decentralisation enables resilience in supply chains, which can experience events such as demand variability and transportation disruptions. MAS-ML is presented in this paper as the solution capable of enhancing supply chain performance, reliability, and cost optimisation in situations characterised by risk and uncertainty, such as the current global pandemic. In addition, this paper presents potential research areas, such as the integration of more enhanced deep learning algorithms, the extension of proposing MAS-ML into other sectors, and the addressing of ethical and transparency concerns associated with AI-based decision-making systems. The proposed MAS-ML framework improves the adaptability and resiliency of supply chains, providing a flexible solution for modern supply chain problems.

The article discusses the results of research dedicated to the thermomechanical processing of products made from chromium-molybdenum steel, similar to grade 35ХМЛ, but modified with vanadium as a modifier. The experiments were conducted under serial production conditions with the aim of improving the technological process. Within the framework of the study, a method was implemented where the forging process was combined with subsequent heat treatment, performed immediately after forging at a specialized station. This approach eliminates the need for re-heating of products, which significantly reduces energy consumption and enhances production efficiency.

During the cooling process of the products, it is necessary to maintain the optimal temperature regime to ensure a controlled exothermic phase transformation of austenite into pearlite. This allows for the formation of a balanced ferrite-pearlite structure, which provides the necessary mechanical properties, including the required hardness range.

The test results confirmed that the correct selection of the isothermal annealing temperature regime contributes to achieving stable operational characteristics of the products. The implementation of this technology in industrial production will significantly reduce energy consumption—by more than 80% compared to traditional heat treatment methods. In addition, eliminating re-heating reduces the overall manufacturing time, which contributes to increased productivity and a decrease in production costs.

Thus, the proposed technological method not only enhances the energy efficiency of production but also ensures the production of products with predictable mechanical properties. Its application in industry could play a key role in optimizing the processing of chromium-molybdenum steels, which is particularly important in the context of the drive to reduce costs and rational use of resources.
