Service identification meets with new challenges with overwhelming rise of categories and numbers of services in big data scenarios. Most of the current service identification approaches have paid little attention to the granularity of indicator for service identification, neither do they provide with any trustworthy monitoring mechanism during the process of service identification. To address the...
This paper analyzes the fatigue monitoring parameter selection and long-distance wireless transmission in deep water drilling riser fatigue monitoring technologies, and designs a deep-sea riser fatigue monitoring system based on MCU+DDS structure. This monitoring system can monitor riser Vortex induced vibration, riser stress and strain and current velocity of seawater in real time. This system can...
Vortex-induced vibration (VIV) is one of the important factors that lead to the free spanning system fatigue damage. The displacement reconstruction which cased by VIV become the main topic in free spanning pipelines fatigue damage monitoring. However, reconstructed the VIV displacement through direct double integrating the vibrate acceleration signal may be lead to the results are not reliable and...
Forestry informatization is a significant symbol of forestry modernization. After the emergency of GIS, it accelerated the development of forestry informatization by provided strong technology support. Mobile GIS is a branch of GIS. It bases on embedded GIS and integrates with a series of cutting-edge science and technology such as advanced GPS, wireless communication technology, mobile database technology...
In this study, we created a set of biodiversity indices (BI) to track the changes of biodiversity components in Daya Bay of the South China Sea. The timely information is thereby obtained for decision-making of biodiversity conservation. The calculated BI score ranged from 0.89 to 1.07 during the periods of 2004-2008, and the mean annual loss of biodiversity ranged from -3.98% to 3.17% and reduced...
The cause of lightning accident of transmission line is due to characteristics of lightning data, so it is very important to count and study the characteristics of lightning parameters. The monitoring method of lightning location system has substituted for the traditional method of collecting lightning data. With the new method, more lightning parameters can be detected, such as the lightning striking...
