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...
In this chapter I will address the issue of the conception of epistemology. As it might appear to one at first, this issue does not belong to the epistemological problematic, because it does not fit into the typical preconceived network of most epistemological problems. In most general form, epistemological questions address the origin, certainty, and extent of human knowledge, specifically the origin...
With the level of the information society getting deeper, the E-commerce, as a new business mode, has developed rapidly with its unmatched advantages. However, a problem of the E-commerce is also getting striking, that is the asymmetric information, which would become an important factor inhibiting the development of the E-commerce. This paper analyzed the performance, the cause and the disservice...
How to find these symptoms in the mass monitoring data of the City Operational System is crucial and important to prevent the accidents happening. The association rule mining method is used to mine rules of infrequent itemsets and more interesting ones, and the outlier condition threshold is set upon the expert experience, searching for qualified data sets to distinguish the exceptional data among...
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...
