THz spectroscopy is a promising technique to study intermolecular interactions and molecular dynamics in organic crystals. In this work, aromatic thiourea compounds with methyl substituents were used as model systems to study the intermolecular interactions between aromatic rings and the dynamics of the methyl internal rotation which falls into the terahertz region. The THz spectra of two phenylthiourea...
Distributed Denial of Service (DDoS) attack presents the following characteristics, that the botnets become extra-large scale, the mode of attack presents a variety of characteristics and the application-level attacks become the main attack approach, which seriously impact on Internet Security. However, traditional software defense detection means have such problem, that the accurate rate is too low,...
The private-owned economy in Henan province has developed rapidly since reform and opening up, which plays an increasingly important role. The private economy of Zhengzhou has developed even more rapidly in recent years, which contributes a lot to the development of the construction of central plains economy zone. This essay makes a full analysis of the state of the private economy development of...
An Industrial expert control system based on transient response patterns and expert system techniques is proposed in this paper. Depending on the features of the closed-loop control system determines the control decision and adjusts the parameters of the controller. The proposed method requires minimal proper information about the controlled plant and, with the linear re-excitation learning method,...
At present there are many methods that could deal well with frontal view face recognition when there is sufficient number of representative training samples per person. However, few of them can work well when only single training sample per person is available. In this paper, we present a training sample enhancement method based on Wavelet Transform (WT) low-frequency band to improve the performance...
