To improve the efficiency and the speed of fault diagnosis for multimode process under big data environment, a new parallel computation fault diagnosis approach, called GFCM-VMD-HM, is proposed for multimodal TE process based on Hadoop platform. Firstly, the global fuzzy c-means (GFCM) clustering algorithm is applied to distinguish the operation modes. Then, Variational Mode Decomposition(VMD) algorithm...
Wavelet analysis is the perfect combination of pure mathematics, applied mathematics and engineering technology which inherits and develops Fourier analysis and has been widely used. This paper mainly introduces the generation and development of wavelet analysis, discusses the characteristics of several commonly used wavelet functions, introduces the application of wavelet analysis in big data and...
Medical Big Data (MBD) is the most critical form of information. MBD over a colossal Wireless Network (WN) is a sophisticated area of concern. Every day WN is becoming more dense and complicated. The MBD can be saved to wireless network after applying suitable Wavelet Compression. The quality of MBD is the most important factor; which means efficient and reliable transmission. Wavelet Compression...
