In this work, we propose an object behavior evaluation system based on wireless sensor network. By the behavior information of objects contacted with human, it can evaluate the behavior characteristics of human under the interactions between human and environment, which goes beyond the traditional evaluation methods that directly monitor human themselves. The system can track and monitor the motion...
A data acquisition and monitoring system of machine tools is designed, which is based on Zigbee and GPRS wireless communication technology. The monitoring and alerting about the safety status of the machine tools operates via the acquisition of such physical parameters as temperature and noise. The hardware such as the CC2530 RF circuit and power module is designed. Based on the CC2530 module and...
The petroleum products leakage from the storage tank bottom could not be discovered in time without store contents emptied out because of the bottom not being accessed easily and the amount of leakage in the beginning being too small to be detected by the ways now available such as interstitial monitoring, liquid sensing probes and cables, volumetric and mass measurement methods, statistical inventory...
The moral hazard in supply chain not only increase the management cost, but also enhance the inside consume, finally decrease the integrative competition ability. As a result, prevent and avoid the moral hazard of the supply chain is an important research aspect. Through revealing the deep incentives of moral hazard in supply chain, and determining reasonable precautions could make the moral hazard...
Ground water level measurements are very important for a wide range of applications in geosciences, agriculture, environment monitoring and mining industry. Currently, reliable and automatic ground water level measurements have not been realized. This paper presents the simulation and design of a segmented resistance sensor for measuring ground water level. Based on this sensor design, we have developed...
Current popular sampling algorithms canpsilat provide accurate approximation of true character under the circumstance of network traffic bursting. In the paper, we develop an adaptive network traffic sampling methodology (MANFC-AT) based on aggregated time-serial evolution trend. The MANFC-AT algorithm adaptively adjusts the time interval between consecutive samples according to the evolution trend...
The maintenance strategy for marine generators is a key factor that affects ship safety and economic benefits. In this paper, on the basis of marine maintenance system theories, by analyzing maintenance after a failure event, preventive maintenance, and condition based maintenance, and so on, a ship maintenance strategy and the corresponding processes are constructed. A risk assessment is made using...
