Monitoring public safety and emergency require equipment that detects the occurrence of emergencies immediately and creates an exact and detailed information about the situation and location of the emergency. Such tools may assist to alleviate desolation under harsh conditions related to natural or human-made disasters by quickly and semi-automatically identifying the type, extent location, intensity,...
Monitoring a person's dietary behavior has many health applications (e.g. weight management). Existing approaches for automatic eating detection using wearable sensors often require custom hardware that may not be practical as their usability and energy efficiency have not been validated. In this paper, we propose to use off-the-shelf Bluetooth headsets to unobtrusively monitor and detect users' eating...
Cyber-Physical System (CPS) is a system of system which integrates physical system with cyber capability in order to improve the physical performance. It is being widely used in areas closely related to national economy and people's livelihood, therefore CPS security problems have drawn a global attention and an appropriate risk assessment for CPS is in urgent need. Existing risk assessment for CPS...
Video behavior analysis is both meaningful and challenging in computer vision. As the monitoring equipment become readily cheaper and available, massive video data have been generated. As abnormal behaviors are rare, manual surveillance may drastically increase the chances of false positives or false negatives. It is hence useful to achieve automatic surveillance. Abnormal behaviors are usually complex...
When confronted with their internal and environmental dynamics, various software systems increasingly require self-adaptation capabilities. The vision above requires the self-adaptation approach to tackle these challenges and some software systems have their own specific implementations. However, in this paper a general supporting framework is proposed for software systems to self-adapt with running...
Valve base controller (VBC) is the core part of control system for Modular Multilevel Converter (MMC) of HVDC Flexible, comprising man-machine interface, current control unit, bridge-arm control unit, valve monitoring unit, etc. Multiple communication methods such as CAN bus, high speed fiber optic are introduced in the system to realize massive data transfer as well as high speed valve monitoring...
Directing against the comparatively serious problems of slagging and ash deposition in 2times600 MW boilers burning Shenhua coal in Guohua Dingzhou Power Plant, test on pollution behavior of heating surface in boiler no.1 has been carried out. Through model for monitoring pollution on the heating surface, the pollution growing behavior, as well as upper and lower limitation of pollution on each heating...
