Food Security Sensor Management Based on RIHA
Zhehui Xiao,Dekui Li,Chinling Chen,Jinlong Zhang 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.11
The coming of information age makes the integrated electronic food security sensor management in industrial field face new challenges. This paper takes the security management food security sensor management of food industry the industrial area as the researching object, discussing the architecture of ASAAC standard food security sensor management, by means of a RSSI-based Information Hiding Algorithm (RIHA) analysis method, it puts forward ideas of assessment on the food security sensor management safety. And uses RSSI (Received Signal Strength Indication) as hidden information carrier and designs. It does not affect original data or bring additional communication cost. The simulation results show that RIHA has high hidden information transmission accuracy without bringing additional communication energy consumption.

Research on effect of rings on coupling vibration in a rigid-disk rotor
YiJui Chiu,Xiao-Yun Li,Guo-Fei Yu,Chia-Hao Yang,Jeng-Shyang Pan,ChinLing Chen 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.2
This paper uses new deductions of the equation of motion and obtains new modes of change that differ from the authors’ previous research. The blade-bending, shaft-torsion and ringbending coupled vibration influence of a single-disk rotor whose blade subsystem was coated with a ring is investigated. In the last two years, the authors adopted two methods, the assumed mode method and finite element method, and compared both parties results. This article continues that work. In this paper, the phenomena of ring joint coupling vibrations are different and interesting. The authors defined two new types, the shaft-blade-ring (SBR) and blade-ring (BR) modes. These two coupling modes can be mutually affected by the shaft, blade, and ring, and no single subsystem predominates. The new change rules of natural frequencies of rotors with two to 15 blades and those of mode shapes are discussed. The influence of the ring thickness and rotational speed are also studied in this paper.
