Unfortunately  the field of NR IQA has been largely unexplored. The basic problems in NR IQA are discussed in this paper. and several methods used in NR IQA are explained and analyzed. Finally  an overall NR IQA method is designed. It should be a synthetical index  which applying fuzzy measures and fuzzy integrals  incorporating Human Vision System (HVS) characteristics and adhering to the philosophy of quantifying quality through blind distortion measurement. 2008 IEEE.   Arc fault signatures detection on aircraft wiring system (EI CONFERENCE) 会议论文  OAI收割 6th World Congress on Intelligent Control and Automation, WCICA 2006, June 21, 2006 - June 23, 2006, Dalian, China Hongkun Z.; Tao C.; Wenjun L. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 In this paper an arc fault detection method Is proposed based on characteristics of the fault current of an electric arc. A localized signal processing method Is developed using wavelet analysis to decompose the differential current signal Into a series of wavelet components  each of which Is a time-domain signal that covers a specific frequency band. Thus  more distinctive signal features that represent arc faults and other fault transient phenomena are extracted. As a result  by quantifying the extracted features  an arc faults are distinguished from phenomena similar to arc and other fault transients using the differences In the quantified features. Simulation studies have demonstrated that the proposed method Is reliable and simple. 2006 IEEE.   Enlightenment on sustainable management of water resources from past practices in the Bositeng Lake basin, Xinjiang, China 会议论文  OAI收割 Iahs Publication 作者:  Xia J. 收藏  |  浏览/下载：27/0  |  提交时间：2012/06/30 Bositeng Lake (China)  quantifying method  sustainable management  water  resources  challenge
