With the rapid development of Internet technologies such as cloud computing and big data, the scales of distributed information systems in big companies have grown to enormous sizes. Automatic detection and diagnosis of system faults in the large-scale information systems is complicated and important in both practice and research. In this paper, we propose a Graph-based Fault Diagnosis approach in...
Continuous evolution of virtualization-related technologies have benefit greatly flexibility and reliability of software system. However, although virtualization removes binding between application and server underneath, it complicates the regular runtime hierarchy into an intricate structure, where cross-layer monitoring and holistic evaluation becomes challenging. Currently lots of monitoring practices...
Brain-Computer Interfaces (BCIs) are a new way that can enable information exchange without any movement but just through the mind. This technology improves the communication and control capabilities of human beings with the outside world, which often uses to help disabled people. In recent years, BCIs begin to be explored to assist people in some extreme conditions such as in space to control space...
Considering the hysteresis of switch timing control system used in the industrial farming of pleurotus eryngii, respiration control experiments were carried out with given temperature, humidity and light in a factory farm. Planting environment was monitored by a remote monitor system with a radio frequency module. A CO2 concentration prediction model is developed based on BP neural network and a cycle...
Aiming at the defects of the existing technology for Pleurotus eryngii cultivation environment monitoring system in Ningxia Pengyang County, such as: transmission of the data is not stable, small monitoring range and the sensors cannot move conveniently, only the environmental data in a fixed position within each mushroom shed can be collected, need to lay a lot of cables between the collector and...
Monitoring traffics between applictions deployed in a distributed computing system (DCS) can help analyzers perceive the dynamic load of each application, and detect the anomalies in all the running processes. However, due to the factors of high dimension and strong periodicity, the traffic data is difficult to visualize and interpret. In this paper, we propose a traffic monitoring approach based...
As chronic diseases have become very common recently, lots of people are faced with sub health problems. Two major reasons contributing to these problems are the increasingly busy lifestyle and working pressure. Therefore, People have no time to monitor their health although they are more and more concerned with health problems. This problem may be settled with the development of mobile communication...
A wrist-worn health monitoring terminal is developed to realize body's multi-parameter measurement by including a common mobile phone. The common mobile phone wireless connected to the health monitoring terminal is included to be the memory and the displayer. Also the mobile phone acts as the wireless module to communicate with the health service centre. The physiological parameters includes body...
A new kind of wrist-worn health monitoring terminal is developed to realize multi-parameter measurement, wearing facilitates and reliable data transmission. The physiological parameters includes body temperature, pulse rate, breath rate and waveform, blood pressure, electrocardiograph(ECG), electroencephalogram(EEG) and the level of blood glucose real-timely. This terminal is designed by modules,...
This paper mainly studies the development and related fields of Tele-medicine, and then points out the prospects for it. Finally, we put forward a complete and feasible set of applications for Tele-medicine-a design of portable monitoring system for human physiological parameters.
Database system based on VB was developed by collecting the investigation and testing data of endemic area in the West of Jilin Province. The water quality assessment module of the system was applied to assess the drinking water safety. The results show that the groundwater quality in this area is mainly level IV and V, and taking up 68.99% of all the samples. The reason of the poor water quality...
A novel study on monitoring system of car-guardrail collision accident building by wireless sensor networks is introduced in this paper. According to the research on the collision features of the simulation of car-guardrail, it is found that the vibration features of the guardrail within the accident have a good performance to the accident identification. The vibration data of the guardrail are recorded...
Ship dynamic and video monitoring system at sea aims at improving safety of ship sailing and providing help for salvage. In this system, wireless communication technology of CDMA1X is used to transfer GPS dynamic positioning information and ship video. As to the special communications at sea, the actual bandwidth of single channel CDMA1X is too low to transfer video. In order to cope with this problem,...
AVS-M is part seven of AVS standard, which is the second generation source coding standard of China. Because the system resource is limited in mobile platform compared with AVS P2, AVS-M has lower complexity, and is suitable for mobile-multimedia applications. The performance of AVS-M is close to H.264/AVC in the case of low rate bitstream. It is very important to increase the real-time encoding and...
