Special Issue Information

Dear Colleagues,

With the advancement of machine learning and artificial intelligence technologies in the current era of big data, scientists can acquire a better understanding of our surrounding environment by synergizing different datasets and using properly trained and validated algorithms, for example, satellite imageries and datasets, local and urban monitoring networks, fine-scale emission inventories, meteorological and atmospheric attributes, numerical modeling, and post-processed outputs. Measurements obtained from low-cost sensors and raw observational datasets can also be integrated into the model development process to fine-tune specific dependent parameters of the entire algorithmic framework, thus enhancing the validity and reliability of the developed algorithms. This is particularly useful when attempting to conduct large-scale spatial and temporal assessments, as well as associating relevant predicted results to enhance health qualities and implement relevant policies. Further, insights obtained from the algorithmic development process do not have any geographical limits, and the appropriate combination of various models with the latest data analysis tools has proved to return better retrieval results in the long run. Therefore, it is of particular interest to explore how digital advancement could gradually lead to more effective and systematic environmental retrieval and monitoring.

This Special Issue seeks to publish and promote new and innovate ideas in the development of trustworthy algorithmic frameworks for the purpose of environmental monitoring and environmental data analysis, as well as the application of these frameworks in practice to conduct large-scale trend analyses and assessments. Original research articles and literature reviews of relevant topics are highly welcome, contributing to a joint effort to steer technological advancement forward, and as a result create a sustainable world in the foreseeable future.

This research analyzes a multi-server retrial queue with two types of calls: working vacation and working breakdown. The incoming call may enter the retrial queue and attempt to seize a server after a random delay if all the servers are unavailable upon arrival. In its idle time, the server makes outgoing calls. All the servers take a synchronous working vacation when the system empties after regular service. The system may fail at any time due to disasters, forcing all the calls within the service area to leave the system and causing all the main servers to fail. When the main servers fail, the repair process begins immediately. The standby servers serve arriving customers at a lower level of service during the working breakdown or working vacation. For this model, we derive an explicit expression for the stationary distribution with the help of the quasi-birth-and-death process and the matrix geometric method. Further, the formulas of various system performance indices are developed. An application example is given and several numerical experiments are performed to verify the analytical results. We also perform the comparative analysis of retrial queues with/without two-way communication and two-way communication retrial queues with/without disasters. The results reveal that the proper consideration of outgoing calls to the server can reduce the average time spent in the buffer. Furthermore, a more reliable server reduces the server idle rate.

Hydraulic dissolution, driven by carbon dioxide-rich precipitation and runoff, leads to the gradual breakdown and removal of soluble rock materials, creating unique surface and subsurface features. Dissolution is a complex process that is related to numerous factors, and the complete simulation of its process is a challenging problem. On the basis of deep investigation of the theories of geology and rock geomorphology, this paper puts forward a method for simulating the dissolution phenomenon on a rock surface. Around the movement of water, this method carries out dissolution calculations, including processes such as droplet dissolution, water flow, dissolution, deposition, and evaporation. It also considers the lateral dissolution effect of centrifugal force when water flows through bends, achieving a comprehensive simulation of the dissolution process. This method can realistically simulate various typical karst landforms such as karst pits, karst ditches, and stone forests, with interactive simulation efficiency. Full article
