Abstract.To address the challenge of extracting bearing fault features, this study proposes a new rolling bearing fault feature extraction method based on the Sparrow Search Algorithm (SSA) to optimize Variational Mode Decomposition (VMD) and Multipoint Optimal Minimum Entropy Deconvolution with Convolution Adjustment (MOMEDA). Firstly, SSA is employed to identify optimal parameters in VMD, followed by the utilization of correlation coefficients and kurtosis to filter relevant Intrinsic Mode Function (IMF) components. Subsequently, MOMEDA is applied to denoise the reconstructed signal, mitigating the … Read more →

Abstract.In response to the phenomenon that existing image restoration algorithms have blurry edges, incoherent textures, and lack clarity and delicacy for large-area missing images, a two-stage generative adversarial image restoration algorithm based on dilated neighborhood attention is proposed. This algorithm decouples image restoration into edge structure restoration and texture structure restoration, introduces a dilated neighborhood attention mechanism, and enhances the generator's focus on important information and structures in the image by constructing a residual attention network, thereby … Read more →

Abstract.Due to its structural advantages, biochar has developed pore structure, large porosity, surface potential energy, and more oxygen and nitrogen functional groups on the surface, which can adsorb and solidified heavy metals and organic pollutants in contaminated soil to achieve the purpose of repairing contaminated soil. At the same time, adding an appropriate amount of biochar to the soil can also enhance soil nutrition and improve water retention performance, and promote the good development of microbial systems. At present, it has become a research hotspot of contaminated soil remediation. In … Read more →

Abstract.In life, opportunities and challenges coexist, and success and failure are linked. In today's society, it is difficult to figure out the factors that affect people's success or failure; however, there is always a way to succeed and a reason to fail. In an environment where people aspire to success and seek to realize their self-worth, it is a long and arduous process to learn to overcome the causes of failure, uphold one's beliefs, and ultimately achieve success, and the American film The Pursuit of Happyness can bring inspiration accordingly. The film is based on a true incident, and the main … Read more →
