Aiming to the time-domain feature of fault signal, the adjacent difference group sparse representation (ASDGSR) is developed firstly. Moreover, a weighted parameter-setup method is developed to set the regularization parameter of ASDGSR adaptively. Furthermore, a majorization–minimization (MM)-based...
The difference between the histograms of the downsampled images (size: 256 × 256) before and after performing the LSB+ hiding on the whole image "Oregon" (size: 512 × 512) with θ = 1. Full size image Figure 10 The pixels in black are chosen as the neighbors of others so that onl...
IR images are effective in capturing target objects under low-illumination conditions by leveraging the difference between the target object and environmental thermal radiation. However, these images often lack sufficient information on the edges and texture details of the target. On the other hand, ...
On the basis of SCR, the collaboration-representation-based classification with regularized least squares (CRC_RLS) method considers the difference in regularized residuals both in the target category and other categories, which has more stable results in pattern classification problems [27]. In ...
Date difference in Days,hours minutes and seconds. DATE FORMAT MMYYYY for current date Date format with slashes instead of dashes Date is showing 1900-01-01 instead of blank date or time that are too negative or large to display as ### Date time in Open Query Date Time issue while expor...
Fault Detection of Rolling Bearing Using Sparse Representation-Based Adjacent Signal Difference The early defects in bearings tend to result in periodic impacts and thus cause impulse components in vibration signals. However these fault features are a... Y Sun,J Yu - 《IEEE Transactions on Instrumen...

In the equation, v is the southward velocity, S0 is the density of ambient water, ΔS is the density difference with the ambient water and A is the cross-sectional area. Time series of the freshwater transport at the upper bay resembled that of nitrate and TSS (Figure 1, Figure 3 and...
