Due to the widespread deployment and low cost, WiFi has become one of the most attractive research fields in indoor environments, for example, almost every smart mobile device can be a WiFi signal receiver and transmitter. Various WiFi based indoor localization approaches have been proposed under different circumstances. However, most of them are only suitable for relatively small indoor environments,...
Device-free localization (DFL) is an emerging wireless localization technique where the target does not equip with any electronic tag for communicating with the localization system. It has been found numerous practical applications such as human health and medical care with the help of location detection and behavior analysis, intrusion detection, security safeguard, and emergency rescue. In the DFL...
Pulse wave transit time (PTT), as measured between the ECG R-wave and the arterial pulse wave at a distal site, has been previously reported to linearly correlate with blood pressure (BP). This study reinvestigated the relationship where various doses of epinephrine were administered to three anesthetized dogs to invoke a wide range of hypotension. The invasive systolic blood pressure in the left...
With the development of the society, distance education and training gradually shows some characteristics similar to the service industry, such as invisible, cannot be stored, heterogeneous, serving and consuming in the same time and so on. To gain a bigger market share in competition and more reputation and brand value in development, distance education and training institutions must pay great attention...
The number of files stored in a personal computer is increasing very quickly, so it is difficult for users to find the information they want. One desktop search engine named SoDesktop is proposed in this paper, which is composed of four modules including Data crawler, Task scheduler, Data indexer and Data searcher. The implementations of these four modules are described in details, and the implementation...
This paper presents a fault diagnosis approach that is the combination with Gaussian mixture models and variable reconstruction. Usually, the traditional multivariate process monitoring techniques has the fundamental assumption that the operating data should follow a unimodal Gaussian distribution, but it often becomes invalid due to the practice different operating conditions. The Gaussian mixture...
This paper make simatic touch panel and PLC for centre to design industrial batching system, using Wincc flexible as HMI configuration software. The designed system presents good functions such as dynamic real-time monitoring, auto-alarm, recipe supervise, print outcome and so on. It has advantages of stabilization, security, easy to operate and more faster, finally realize the system's batched and...
The pollution of Qinhuangdao Port is the bottleneck of economic development, so how to correct the environmental assessment of the work environment has important significance. The main pollutants in Qinhuangdao port is coal dust pollution, through various observation points on the measurement indicators of pollutants by EPA experts scoring can get a group of data, and then through various BP neural...
