With the development of the Rough Sets and Neural Network, dynamic prediction research on financial crisis has become as a developing trend. Based on this situation, this paper makes use of the Rough Sets' attribute reduction technique to reduce the financial index firstly, then imposes the Neural Network to train network so as to establish financial crisis alarming model to drop out enterprise's...
In regards to applications like 3D seismic migration, it is quite important to improve the I/O performance within an cluster computing system. Such seismic data processing applications are the I/O intensive applications. For example, large 3D data volume cannot be hold totally in computer memories. Therefore the input data files have to be divided into many fine-grained chunks. Intermediate results...
Voltage sag has become one of sharpest issues on power quality in modern social. In this paper, voltage sags indices such as SARFI, severity index, energy index are summarize, analyzed and compared, and the energy index is improved. Four indices are proposed, that is: statistical index, severity index, event time indices and cost indices, and the recommended reason is also explained.
