This paper aims to achieve the measurement of plasma parameters in Galatea. Firstly, we research the measurement principle and the theory of electron density and electron temperature calculation. Then, we analyze the probe characteristics, select the cylindrical probe to measure plasma space potential, the spherical probe to measure the plasma electron density and electron temperature. Finally, we...
Network Intrusion Detection System (NIDS) plays an important role in providing network security. Efficient NIDS can be developed by defining a proper rule set for classifying network audit data into normal or attack patterns. Generally, each dataset is characterized by a large set of features, but not all features will be relevant or fully contribute identifying an attack. Since different attacks...
To improve the information security level of the wide area protection system, the functions of the system and IED are analyzed. The communication data types of the system and their communication requirement are offered. The main security threatens and key information security technologies are analyzed emphatically. The key information security technologies include digital signature technology, encryption...
To overcome the disadvantages of full-wave Fourier algorithm that can not filter decaying DC component and has bad frequency characteristic, Morlet complex wavelet amplitude algorithm is studied. After analyzing the influence of parameters m, c and N to Morlet complex wavelet amplitude algorithm and the question that one-circle Morlet complex wavelet amplitude algorithm can not filter the two times...
