In China, thousands of foodborne diseases occur every year. It is proved that prevention is the most crucial for control ing foodborne disease. In the research, food safety monitoring system, laws and early warning system in the US and EU were introduced to explore the successful experience and monitoring or control mode suitable for China.展开更多

A real ti me monitoring system of pipeline defect is established. For unexpected accidents of pipeline leakage, several methods of signal processing, including wavelet an alysis are utilized. The leakage can be located accurately in time. This system is applied to many long distance pipelines in China, which has made great contri butions to the economy.展开更多

However, little attention is paid to evaluate the functional state of a patient in sleep. The efficiency of prescribed medicines is also determined in wakefulness. The effects of these drugs during sleep are usually out-of-sight of a physician. Human psychoemotional state during wakefulness is closely related to sleep. Various serious disturbances in physiological functions appear during the night sleep. They include cardiovascular disorders （hypertensive crisis, myocardial infarction, arrhythmias, stroke, etc.）, which may cause sudden death. A large body of evidence shows that stress is followed by sleep disorders. They serve as a factor, which contributes to the development of stress. It should be noted that sleep is the major anti-stress factor. The vicious circle is formed, which can be revealed by a complex control of human physiological functions during wakefulness and sleep. We developed a new methodology and constructed an information-and-equipment device for monitoring of vital physiological functions of humans during sleep in a real everyday life. This approach holds much promise for the diagnosis of disease and evaluation of therapeutic efficacy.展开更多

The robot can adaptively adjust its status according to diameter (from 400 mm to 650 mm) of pipeline. The maximum detection distance is up to 1 000 m. The method of video coding in the system is based on fractal transformation. The experiments show that the coding scheme is fast and good PSNR. The precision of on-line detection is up to 3% thickness of pipeline wall. The robot can also have a high precision of location up to 0.03 m. The control method is based on network and characterized by on-line and real-time. The experiment in real gas pipeline shows that the performance of the detection system is good.展开更多

The system will be able to make an analysis that assures a more efficient management of each plant and of the whole system. In the first part of this study, the features of the monitoring system that allows to monitor the operating parameters and to discover the issues before they actually become dangerous for the plant have been identified. The data collected in the different solar thermal systems realized in Italian jails have been analyzed. The results of these elaborations allowed us both to find out some anomalies of functioning of the plants, and to optimize the management of the whole plant in a more efficient way.展开更多
