In recent years, as the development of SNS, data is produced more and more quickly. "Store-and-process", the old style of data processing is not suitable now. Obviously, stream processing systems are more capable of such tasks. But currently, these systems only run on the fixed resource, they cannot take advantage of the "pay as you go" feature which is provided by the cloud. Besides,...
A system which was proposed used temperature sensor, pressure sensor, infrared sensor and wireless communication network to monitor the productive process of boiler. Each wireless sensor module was spreaded each relevant position which needed to monitor in the productive process of boiler. The monitored data was sent to the master control box to analyse. The productive process was monitored by the...
In this paper, the problem of change detection from Multi-temporal remote sensing images is addressed. To that end, we present a measure of the observed change by combining the two related tasks. In their preliminary design stage, a method constructs difference image by wavelet-based fusing the results of differencing operation and log-ratio operation. Then, by taking into account the spatial-Neighborhood...
In this work, we focus on the problem of fault tolerant data collection in heterogeneous Intelligent Monitoring Networks(IMNs). IMNs are expected to have a wide range of applications in many fields such as forest monitoring, structural monitoring, and industrial plant monitoring. We present our fault tolerant data collection scheme in the hierarchical structure of IMNs. We use an interesting technique...
Measurements of wireless sensor networks (WSNs) are often polluted by random measurement noises and corrupted by unpredictable sensory reading errors. For a typical field monitoring scenario, this paper considers to correct sensory reading errors and recover the monitoring field, subject to measurement noises. The key factor to enable successful de-noising and error correction is that the monitoring...
Heartbeat mechanism is widely used in designing high availability distributed system. In this paper, we design a multi-level heartbeat protocol, which consists of two kinds of heartbeat protocols: multipoint heartbeat protocol and bidirectional heartbeat protocol. Multi-level heartbeat protocol is very convenient for the nodes to join and leave the heartbeat protocol and can also avoid the single...
The main thesis of this project is on dynamic monitoring, analysis and evaluation of large-scale projects to provide a 3-dimensional project evaluation and effective basis for investment decisions for government from nationwide to different industries. This paper presents a dynamic monitoring and evaluation system architecture, and model on comprehensive evaluation and management applications for...
The fault diagnosis in tribosystem was a difficult problem due to the complex structure of the tribosystem, the nonlinear character of the tribosystem and the presence of multi-excite sources. Usually, one method of fault diagnosis can only inspect one corresponding fault category. In this paper, oil monitoring and vibration monitoring methods were utilized together to diagnose the rolling bearing...
