Gearbox fault diagnosis method based on optimized VMD-NLM with 1DDRSN by WAN Zhiguo, ZHAO Wei, WANG Zhiguo, DOU Yihua

“…ObjectiveAiming at the problem of poor accuracy of gearbox fault diagnosis under noise interference, a new fault diagnosis method for gearboxes based on the denoising methods of optimized variational modal decomposition (VMD）and non-local means (NLM) was constructed, combined with a one-dimensional deep residual shrinkage network (1DDRSN).MethodsFirstly, the parameters in the VMD were automatically optimized using the subtractive average-based optimization (SABO); secondly, each intrinsic mode function (IMF） after the decomposition of the VMD was filtered using sample entropy, and the noise-containing components were subjected to the NLM denoising and reconstruction; then, a residual network that combines the attention mechanism with soft thresholding was introduced to model 1DDRSN; finally, the denoised and reconstructed signals were inputted into the 1DDRSN for fault diagnosis and identification. …”

AN ASSESSMENT OF BUILDING ELEMENTS’ PRONENESS TO VARIATION IN NIGERIA by Babatunde Solomon Olusola, Babalola Olubola, Godwin Onajite Jagboro, Akintayo Opawole

“…The paper further identified involvement of professionals at initial stage of project, client's involvement at planning and design phase, clear and thorough project brief and thorough detailing of design respectively as control measures of proneness of building elements to variation. The study recommended that the identified building elements which have been known to have a high degree of susceptibility to variation are to be given utmost consideration during the design and construction process in order to minimize their effects and contributions to variation with overall aim to improving construction project delivery. …”
