After defining the idea of Convert channel, this paper analyses detecting methods of convert channel including syntactic information flow analysis and semantic information flow approach. This paper put forwards one method of improved syntactic information flow processing whose core idea is to design PC to sign every row of program in this kind of method, and detect the covert information flow by this...
A two-stage data envelopment analysis (DEA) model is created to provide valuable managerial insights when assessing the dual impacts of operating and governmental strategies for the Science and Technology Activity Efficiency. This new model is used to analyze the inputs and outputs for the science and technology activity in the region and how to achieve efficiency systematically. In this paper, it...
Wireless network is the trend in the future, but the signals of wireless are often covered each other in the transmission, so the hiding channel is the unavoidable. This paper studies the execution mechanism in transmission especially and lets the program counter to follow the change of information flow in the execution progress. The type of program counter (pc) makes dynamic changes with the type...
High-voltage power system equipment has the following problems during the long-running process: surface oxidation and corrosion, fastening bolt losing, the junction between contact and bus row is aging etc. They make the equipment is very hot, even produce the serious accident. And there is high-voltage exposed in the switchgear, the space is very small, so manual temperature measurement is impossible,...
This article describes the hardware design and software design of ARM-based flow totalizer meter. The greatest advantage of the instrument system can be to measure the measured objects of flow with high accuracy in different regions, having the functions of remote online management over IP. and system software upgrade. At the same time of the flow measurement, pressure and temperature are also measured...
