For support the global energy Internet strategy, the communication security of the coordinated hydro and wind power generation(CHWG) should be protected. The CHWG-Information and Communication Protection Network (ICPN) is proposed by analyzing the demand of communication technology for CHWG and modern power grid information technology. The overall functional architecture of ICPN was built, and key...
Accurate representation of currently actual land surface types at regional to global scales is critical for land surface parameterization in numerical weather, climate, hydrological and ecological models. Depending on the time scale, monitoring land surface type changes is also increasingly important for natural disaster assessment and natural resources management. To provide near real time surface...
Vehicle monitoring systems have recently become a urgent necessity. This paper describes a high accuracy differential positioning vehicle terminal based on BeiDou Navigation System, comprised of a BeiDou differential positioning module, a GPRS communication module, and a S3C 2440A control module. This vehicle terminal can perform real-time data acquisition and storage, and the information can be displayed...
Landslide occurring around big reservoir and other water conservancy facilities affects the displaced residents' living and the safety seriously. Recently, as a newly rising remote observation technique, ground-based synthetic aperture radar interferometry has been development and widely used in related investigation and assessment field since it has efficiency and accuracy advantages on monitoring...
A radio monitor station (RMS) collects the radio signal information of a large range of frequency for the management of radio bandwidth usage. To meet the challenges of large dynamic data, we have developed a domain specific management information system (MIS) for the radio monitor stations. The system design and implementation are described in the paper. An algorithm is provided to work with the...
Strain gage measurement is widely used in electronic industry as an effective tool for assessing and controlling risk levels. However, the accuracy of strain gage measurement is easily influenced by many factors, among which sampling rate/scan frequency setting of a measure equipment remains an important one. Some critical strain values may be missed if the sampling rate is too low, on the contrary,...
RFID (radio-frequency identification) is an emerging technology with extensive applications such as transportation and logistics, object tracking, and inventory management. How to quickly identify the missing RFID tags and thus their associated objects is a practically important problem in many large-scale RFID systems. This paper presents three novel methods to quickly identify the missing tags in...
We report on an experimental exploration of ex vivo measurements and real-time monitoring of the motions of heart wall for perfused rat hearts, by employing a surface-contact type of electromechanical probes based on piezoelectric transduction. In a hybrid experimental apparatus consisting of a conventional heart perfusion system and external electromechanical probing devices and circuitry, prototyped...
In order to predict the reliability of the product with high reliability and long life, the accelerated degradation test (ADT) is commonly applied. However, in the studies of optimizing the ADT plans, there is nearly no researches on how to select the test stress levels. In this paper, the drift Brownian motion is selected as the degradation model. The optimization of the selection of the stress levels...
Data storage is an integral part of IT infrastructures, where Quality of Service (QoS) differentiation amongst customers and their applications is essential for many. Achieving this objective in a production environment is nontrivial, because these environments are complex and dynamic. Numerous practical and engineering constraints render the task even more challenging. This paper presents SLED-2,...
Detecting changes in stock prices is a well known problem in finance with important implications for monitoring and business intelligence. Forewarning of changes in stock price, can be made by the early detection of changes in the distributions of stock order numbers. In this paper, we address the change detection problem for streams of stock order numbers and propose a novel incremental detection...
Spyware is a kind of malicious code that is installed on victims' machines without their content. They spy on the users' behavior and compromise their privacy, while transmitting sensitive information to some remote servers. Current anti-spyware tools are similar to anti-virus products in that they identify known spyware by comparing the binary image to a database of signatures. Unfortunately, these...
