“…In recent years, large-scale environmental problems need highly effective and high-precision environmental assessment and prediction. However, for the established architecture and solution of differential equations, it is a considerable challenge to obtain high-precision results with fast speed in a large-scale river network simulation [34]. In order to increase efficiency of decentralized models, parallel computing methods are widely used.…”

High-precision and efficiently distributed discrete element models for water environment simulation are urgently needed in large-scale river network areas, but most distributed discrete element models are serially computed and need performance improving. Parallel computing and other common methods for models’ high performance have large labor costs and are complicated. We put forward a new mesh reduced method for promoting computational efficiency with grid re-organization according to the structure and algorithm characteristics of 2D and 3D numerical models. This simple and cheap method was adapted to a classical three-dimensional hydrodynamic and sediment model (ECOMSED) for model improvement and effective evaluation. Six schemes with different grids were made to investigate the performance of this method in the river network area of the Three Gorges Reservoir Basin. It showed good characteristics of simulation performance and model speed-up. We concluded that the method is viable and efficient for optimizing distributed discrete element models.

Abstract-There are many difficult challenges, such as variety, quantity, distribution etc. in the unstructured data tracking management, which lacks an effective file tracking management solution. In this paper, based on the storage mechanism of HBase, we propose a data life cycle tree storage structure, and realize the whole life cycle tracking ȡ of the file. At the same time, the system can provide visual analysis services, such as frequency of operation, distribution of hot spots, data types, the breadth and depth of the life cycle tree, and the data volume trend prediction etc. Compared with common data management systems, this system can be more efficient and fast to query and build the data life cycle tree, and quickly realize the visual analysis of the document.

Abstract. Operating requirement of air traffic control system, the multi-platform real-time message-oriented middleware was studied and realized, which is composed of CDCC and CDCS. The former provides application process interface, while the latter realizes data synchronism of CDCC and data exchange. MQM, as one important part of it, provides message queue management and, encrypt and compress data during transmitting procedure. The practical system application verifies that the middleware can simplify the development of air traffic control system, enhance its stability, improve its systematic function and make it convenient for maintenance and reuse.
