Due to the complex and changing drilling conditions large scale of logging data, it is extremely difficult process data in real time identify dangerous working conditions. Based on multi-classification intelligent algorithm Stacking model fusion, 24 h actual an XX well are classified identified. The divided into standpipe connection, tripping out, in, Reaming, back circulation, drilling, other ...

Preceding NMR experiments show that the conformation of tandem GA base pairs, an important recurrent non-canonical building block in RNA duplexes, is context dependent. The GA base pairs adopt "sheared" N3(G)-N6(A), N2(G)-N7(A) geometry in the r(CGAG)(2) and r(iGGAiC)(2) contexts while switching to "imino" N1(G)-N1(A), O6(G)-N6(A) geometry in the r(GGAC)(2) and r(iCGAiG)(2) contexts (iC and iG ...

Recently, machine learning-based technologies have been developed to automate the classification of wafer map defect patterns during semiconductor manufacturing. The existing approaches used in pattern include directly learning image through a convolution neural network and applying ensemble method after extracting features. This study aims classify defects more effectively derive robust algori...

This paper is concerned with lip localization for visual speech recognition (VSR) system. We shall present an efficient method for localization human’s lips/mouth in video images. This method is based on using the YCbCr approach to find at least any part of the lip as an initial step. Then we use all the available information about the segmented lip-pixels such as r, g, b, warped hue, etc. to s...
