To test the applicability of ADV, two techniques (ADV and PIV) have been applied for simultaneous measurement of an open channel flow. Comparison of the results (time-averaged velocity, turbulence intensity, Reynolds stress, and power spectra) reveals significant difference in the performance of PIV and ADV. For the ADV measurement in particular, the sampling frequency exerts little influence on the...
In order to guard against the leakage of important data in the system, a new model of data protection is proposed in the paper, which is also targeted at the shortcomings in the existing data protection technology in the field of data leakage prevention. By taking advantage of TPM data protection technique as well as the combination of symmetric encryption and asymmetric encryption, a new data protection...
Trusted computing technology is the mainstream technology for information security. It has technical extension for asymmetric computing technology and password protection technology as the foundation, to allow information security technology development from passive defense turned to active defense direction. Security strategy from the nets facilities to internal system security, and security deepening...
