Low-speed hoist bearings are characterized by fault features GATSBY STYLING SOLID that are weak and difficult to extract.Multipoint optimal minimum entropy deconvolution adjusted (MOMEDA) is an effective method for extracting periodic pulses in a signal.However, the decomposition effect of MOMEDA largely depends on the selected pulse period and fil
Background: Waste collectors face multi-faceted health risks including exposure to musculoskeletal disorders, respiratory diseases, and workplace injuries because of their hazardous work environment.The purpose of this study was to determine the risk factors that affect health of the waste collectors across Bangladesh.Methods: Data on a cross-secti
Tests are updated and revised periodically in order to remain current, valid and reliable in a competitive psychological testing industry.Despite the prevalence of test revisions, especially in recent years, a number of authors have commented on the lack of comprehensive guidelines for test revision.Whilst some guideline WHITE QUINOA documents from
Deep learning methods have been introduced for fault diagnosis of rotating machinery.Most methods have good performance when processing bearing data at a certain rotating speed.However, most rotating machinery in industrial practice has variable working speed.When processing the bearing data with variable rotating speed, the existing methods have l
