As the inevitable trend of the development of the network management, cyberspace situation awareness is able to fuse multi source and multi attribute information, so as to evaluate and predict the development of the whole network. Cyberspace forecast is the advanced stage of the cyberspace situation awareness, which can help administrators to prevent and respond to the possible problems in the network...
Time-frequency analysis is combined with array processing to develop a direction of arrival (DOA) estimation method. The array data model is constructed in time-frequency domain by cross time-frequency distribution between the output of a reference sensor and those of two symmetric sub-arrays. Accordingly a subspace method is presented based on the average of two sub-arrays' time-frequency data vector...
The construction of Smart Grid will comprehensively enhance the intelligent level of every step in the power grid of our country. The data forecasting ability determines the quality of smart grid. As a result of this, this paper constructs the background value of grey GM (1, 1) model by using threepoint Gaussian quadrature formula, improves its accuracy and the data quality. It indicates that reconstruction...
Based upon the AMSAA model which has been widely used in engineering, a method of defining the time environmental conversion factor was proposed through optimization process, which made full used of the failure data from the same kind of products or the similar products in their development tests, and it made all the development test items into s few typical environment stress types in case the development...
