In this paper we present an Intellectual Property (IP) Management system for the super-capacitor pilot plant which is a hybrid Data Mining and Case-Based Reasoning system incorporates Intellectual Property models to help filter information in order to make Intellectual Property protection decisions more precisely. The main issue of implementing this hybrid(More)
We propose an optical method based on Rayleigh scattering for the direct measurement of cluster tracks produced by a high-pressure gas jet. The tracks of the argon and methane clusters are acquired by a high-speed camera. It is found that the cluster sizes of these tracks are within the range of 7E + 03~1E + 07 for argon and 2E + 06~4E + 08 for methane.(More)
— Wavelet Package Threshold Algorithm (WPTA) is an effective tool for reducing noise from speech signals. Threshold method plays a key role inWPTA. Invariant threshold method, which is commonly used, can lead to severe loss of speech information because of unchanged thresholds. In this paper, three adaptive threshold methods are investigated: Time-Frequency(More)
The detection of cracks in solid infrastructure is a setback of immense significance. Particularly, the detection of cracks in buried pipes is a crucial step in assessing the degree of pipe deterioration for municipal and utility operators. The key challenge is that while joints and laterals have an expected form, the unpredictability and abnormality of(More)
