Abstract: This study, carried out in the heart of one of the world's most important wetlands, focuses on the modelling of certain physico-chemical parameters of the Bikoro peat bogs in the Congo Basin in the north-west of the Democratic Republic of Congo. To this end, we have characterized the above-mentioned parameters using digital modeling based on satellite and in situ data from five villages that make up the three sectors of this territory. Some of the equipment used includes three GPS (Garminextrex 30), Cybertacker v3.435 on Android, cameras (Samsung Wifi 12x + GPS), passive sensors (Radar). We also used an infrared spectrophotometer. The main results in relation to the 240 samples taken show that the pH of the peat bogs in the Bikoro territory varies between (2.600±0.001) and (5.000±0.004), the electrical conductivity measured varies between [85.48±3.17] μS/cm and [97.99±5. 47] μS/cm, the experimental carbon rate reported in tonnes per hectare is 135.3021, the forest carbon stock derived from WWF LiDar is 137.1484 and the spatial distribution of the temperature of these peatlands indicates that it ranges between (22.39±1.05)°C and (24.79±1.95)°C. The results of this study show that the peat bogs in the Bikoro area are wetlands that are both significantly acidic and carbon sinks.

Abstract: Proactive maintenance is a policy aimed at identifying the root cause of failure and correcting it before it causes other problems and leads to machinery failure and breakdown. Implementing this policy can enhance reliability, availability, maintainability, and safety (RAMS) at low cost. A digital twin (DT) is a digital copy of a physical object and its applications will play a leading role in the future of smart manufacturing. DT concept is increasingly appearing in industrial applications including proactive maintenance, enabling accurate identification of equipment condition, proactive prediction of faults, and enhanced reliability. This review paper focuses on the performance and applications of different aspects of DTs in proactive maintenance polices. The review of literature focused on the applications of DT in maintenance management for improving equipment RAMS. The literature review shows that the application of DT techniques in proactive maintenance remains very important for managing the maintenance of critical equipment and production systems. Several DT frameworks for proactive maintenance have been discussed. Furthermore, this study provides a comprehensive roadmap for future research initiatives aiming to fully utilize the capabilities of technology design teams. Finally, the results of this study will be of value to professionals who want and aspire to implement technological design to achieve maintenance excellence.
