APPLICATION OF 5G+EDGE COMPUTING IN REAL-TIME DATA TRANSMISSION FOR SMART MINES
Smart mining represents the core direction of the intelligent transformation in the coal and mining industry, and real-time data transmission is the vital lifeline for the efficient operation and safety management of smart mines. Traditional mine data transmission modes suffer from pain points such as insufficient bandwidth, high latency, poor anti-interference performance and limited access for massive terminals, making it difficult to adapt to the complex underground operating environment and intelligent operation requirements. 5G technology, with its core advantages of high bandwidth, low latency, massive connectivity and high reliability, provides communication support for the high-speed transmission of massive mine data. Edge computing sinks computing power to network edge nodes, enabling local data processing and rapid instruction delivery, which further reduces transmission latency, alleviates cloud computing pressure and ensures the stability of data transmission. Focusing on the integrated 5G+edge computing technology, this paper analyzes the core requirements for real-time data transmission in smart mines, expounds the technical characteristics and integration logic of 5G and edge computing, explores in depth the practical applications of this technology in scenarios such as environmental monitoring, remote equipment control, unmanned mining and emergency rescue, and analyzes the current technical challenges and optimization paths in its application. It aims to provide theoretical reference and practical guidance for the upgrading of the data transmission system in smart mines and the high-quality development of mining intelligence.

SUPPLY CHAIN INSIGHTS OF MODERN AGRICULTURAL MACHINERIES AND ITS CONTRIBUTION TO THE TRANSFORMATION OF THE AGRICULTURAL SECTOR OF BANGLADESH
This study investigates the role of supply chain management (SCM) in facilitating the growth and transformation of the agricultural sector of Bangladesh through modern agricultural machineries, focusing on the case of ACI Motors. Despite agriculture employing a significant portion of Bangladesh’s population, a productivity gap persists due to limited mechanization. ACI Motors recognized this issue and introduced various advanced farm equipment, including tractors, harvesters, and transplanters, sourced primarily from international partners. The research employs both qualitative and quantitative methods, including interviews and a survey of 125 ACI Motors employees. Findings reveal that a well-structured SCM framework—covering planning, import operations, inventory control, and distribution—enables ACI Motors to efficiently deliver machinery across the country, contributing substantially to modernization in agriculture. Statistical tests confirm that dealers are important but not the sole key players in the supply chain, and indicate a positive relationship between ACI Motors’ operations and the sector’s mechanization drive. While challenges such as small landholdings, low purchasing capacity, and policy constraints persist, the study demonstrates how robust SCM practices can address these barriers. Overall, the paper underscores the significance of SCM in advancing farm mechanization for sustainable agricultural development in Bangladesh.

COMPARISON OF STABILITY AND VOLUMETRIC PROPERTIES OF CONVENTIONAL AND STONE MASTIC ASPHALT
This study experimented with and compared the performance stability, volumetric properties, and resistance to rutting of SMA and CMA under simulated traffic loads. It was found in the Marshall Stability Test that SMA can withstand much higher stability (15.8 kN) than CMA (10.6 kN), thus demonstrating that we are far more resistant to any plastic deformation. In addition, SMA demonstrated better flow values (3.2 mm vs. 2.7 mm) and density (2.34 g/cm3 vs. 2.28 g/cm3) indicating suitability for high-stress pavements. Volumetric analysis demonstrated that SMA has higher Voids in Mineral Aggregate (VMA: 17. These are better than CMA (VMA 15.2%, VFA 75%) in binder to aggregate ratio and stability (5%) and Voids Filled with Asphalt (VFA: 80%) compared to CMA (VMA: 15.2%, VFA: 75%). Additionally, SMA's lower air void content (VTM: 3%). Less water ingress and slower aging concerning CMA's 4.0% (vs. 0%) By minimizing binder loss and improving durability, the binder drainage rate of SMA (0.2%) was much lower than that of CMA (0.8%). It found that rutting resistance was higher for SMA (25.3 mm; 50,000 load cycles; 12.0% strain at failure) than CMA (30.6 mm; 50,000 load cycles; 14.2% strain at failure), demonstrating its long-term deformation resistance under heavy traffic. In addition, SMA proved to be stiffer (1500 N/mm vs. CMA’s 1200 N/mm) and better suited for high-traffic roads. SMA finally has superior performance, durability, and rutting resistance and therefore represents an excellent choice for heavily trafficked roads despite a somewhat higher initial cost than HMA, and because the life cycle cost of SMA pavement is lower than for HMA. This enhances properties to reduce maintenance and service life, resulting in cost-effective solutions for high-stress pavement applications. SMA's sustainability and affordability could be further improved if more research is undertaken into recycled materials and their environmental impacts.
