Physical activity (PA) can influence heart rate(HR). But the relationship between HR and PA is hard to describe. In our previous works, HR prediction models based on PA were designed. However, the prediction time length and accuracy are usually hard to compromise. In this study, a new HR prediction method is proposed. The predicted HR is used as the input in the next prediction step. Only HR at the...
In this paper, A production environment monitoring system based on GPRS-Internet was designed and implemented. The system uses ARM9 embedded CPU as its host and realizes monitoring function and man-machine interface by using cross-platform C++ graphic interface library Qt in Linux OS. It sends collected data to remote server by GPRS model and clients realize real-time and long distance monitoring...
The scour is one of the major causes for bridge failure. Scour failure occurs suddenly without prior warning or sign of distress to the bridge. However, there are many challenges to monitor the processes of hydraulic scour, such as measuring equipments are essentially critical, especially during the floods. This paper presents an in-situ scour monitoring system by using the novel mobile wireless technology...
Chilling injury monitoring is conducted by combination of EOS/MODIS satellite remote sensing data and surface meteorological observation data. Surface temperature is retrieved based on split window algorithm and others and the daily minimum temperature is calculated by combination of the surface meteorological observation data. In order to improve the monitoring precision, the remote sensing retrieval...
To effectively implement fair use and rights transfer of digital content in DRM(digital rights management) system, a usage control protocol model MUCON(Multi-UCON) using encryption, digital watermarking technology and traitor tracing technology based on UCON(usage control) is proposed, whose characteristics are feature binding, flexible authorization, traitor tracking, and off-line control. Meanwhile,...
This article base on more than 130 cloudless satellite imagery since 1983, and Poyang Lake water level data from hydrological site since 1993, computed analysis of Poyang Lake water area, established the remote sensing calculation model with Poyang area, demonstration of Poyang Lake area be increased at the same time with water level by XingZi station, and There are significant seasonal variations,...
The paper focuses on the typical wetland in Northeast China, in which region-dedicated design of virtual framework structure is adopted. Considering the characteristics of the wetland, and based on multisource remote sensing data, the remote-sensing monitoring and assessment business system for wetlands and wetland environment background database in Northeast China are established, the remote-sensing...
