The avionics system is an important part of modern fighters, and the analysis and processing of large data generated by the avionics system can provide some guidance for the pilot's decision-making. After analyzing the existing distributed framework, a multi-platform avionics data system is designed and implemented to solve the problem that heterogeneous real-time data generated by a large number...
This paper analyzed the challenges of data management in army data engineering, such as big data volume, data heterogeneous, high rate of data generation and update, high time requirement of data processing, and widely separated data sources. We discussed the disadvantages of traditional data management technologies to deal with these problems. We also highlighted the key problems of data management...
Simulation training system can improve the trainer's ability, a rapid response and safety operating capability in the operation of real ship, to reduce operation accident of sailing. Intelligent examination scoring system uses the professional theory and practical experience as the evaluation criteria, and analyzes the operator's operation process to realize the automatic scoring through the program...
The Core Scientific MetaData model (CSMD) is used by large scientific facilities to catalogue scientific data. The current version provides support to experimental scientists to access their raw data, facility managers for accounting for facility usage and other scientists who wish to re-use raw experimental data. Much of the value in scientific data is provided not only in the raw data but through...
Ice charts have been widely used as a dominated approach or de facto data standard for organizing sea-ice data. These charts are sufficient for safer navigation, oil drilling and so on, but may not be suitable for advanced spatiotemporal analysis in climate studies such as change tracking, factor analysis and data simulation. In addition, sea-ice data presented in ice charts is difficult to integrate...
Today information systems have become the key factor of current computer based engineering applications. So database are designed to support data storage, processing, and retrieval activities related to data management, and they are the key to implementing engineering information models. However, the current mainstream databases are mainly used for business applications, some new engineering requirements...
Modern science is collecting massive amounts of data from sensors, instruments, and through computer simulation. It is widely believed that analysis of this data will hold the key for future scientific breakthroughs. Unfortunately, deriving knowledge from large high-dimensional scientific datasets is difficult. One emerging answer is exploratory analysis using data mining; but data mining models that...
A significant challenge facing researchers is the bridging of domains between the natural and physical sciences through the integration, analysis & visualization of multivariate environmental data from a variety of sources. Typically the temporal, visual and analytical components are not well handled within a single software application or by existing tools, and the final products are often difficult...
The emergence of petascale computing is creating a tsunami of data from peta-scale simulations. Typically, results are analyzed by dozens of scientists who often work as teams. Obviously, it is very important to help these teams by facilitating management, analysis, sharing, and visualization of the data produced by their simulations, and by the auxiliary programs and activities used in the scientific...
Integrated Ocean Observing System (IOOS) customer projects are designed to initiate, extend and adopt IOOS data management and communication, observing or modeling and analysis components to add value to customers and subsequently provide information about the value of an integrated ocean observing and modeling system that is coupled and managed as a system, rather than individual sources of data,...
To meet the organization process measurement need, this paper presented an integrated measurement model for the software process management, which establishes the relationship between organization unit, role definition and the GDM analysis result of business goal. This model supports such process measurement activities as the data collection, data analysis and communication of analysis result. When...
In many research fields of numerical simulations, programs often produce a large amount of mesh data with complex structure. It is a fatal bottleneck for scientists to manage such large-scale simulation data. In allusion to typical data characteristics of multi-dimension and multi-variables numerical simulation programs, the relativity between time and space, and practical problems of data exchange...
Network situation awareness (NSA) is a new idea of network security, it is different from normal network security technique for its visualization and high-level data management, transform the abstract data to knowledge that human can understand, help network manager to make decision. Present NSA model have some weakness donpsilat fit to network security. This paper promote a improve model of the NSA,...
