As an integrated control system of the whole boiler-turbine and its electrical system, the Distributed Control System (DCS) has been widely used in thermal power plants. However, due to the large amount of microprocessor-based protection and monitoring devices in the auxiliary power system, some operation information in the devices can not be detected by the DCS. The devices provides a large number...
An on-line monitoring technology of the central air conditioning energy efficiency is presented. Based on this technology, a monitoring system is designed. This system can achieve the real-time monitoring, optimization and adjustment of the energy efficiency of central air conditioners. Because of the improvement of the energy efficiency of central air conditioners and the depression of user energy...
In practical application of electro-mechanical impedance (EMI) technique, the monitored structure is constantly undergoing change due to external boundary conditions and the surrounding ambience. This change, in most cases, is considered to be normal and a part of the everyday use of the structure. The aim of this paper is to examine and obtain a better understanding of practical issues that are a...
It is the first time that the Antarctic super low frequency (SLF) and extremely low frequency (ELF) radio atmospheric noise has been measured in China. The time domain profile and the frequency domain profile of the data have been gained by analyzing and processing the measured data, and the change characteristic of the radio atmospheric noise has been discussed along the day, night and the frequency...
A hybrid method combining electro-mechanical impedance (EMI) technique and artificial neural network (ANN) is proposed to detect damages in structural systems. The structural members are treated as Timoshenko beams for flexural motion as well as the damages are modeled by changes in Young's modulus in the damaged area. For a structural member with surface-bonded PZT wafers, a coupled system is considered...
IT service providers face a great need to improve the quality of services by IT service management (ITSM) in highly complex IT Environments. This pressure demands a strong collaboration from both the external service providers and internal service providers. However, providers still lack the necessary support, in methodologies and tools, to achieve efficient collaboration strategies. This paper proposes...
This paper introduced our independently developed media monitoring system on city image from five aspects: background, process, architecture, index and application. The system targets on monitoring, analyzing and evaluating a city's image, then help the city accurately know about itself, monitor its news and issues, propose its public relations strategies, market its city brand while perfectly shape...
