The data-driven intelligent fault diagnosis method of rolling bearings has strict requirements regarding the number and balance of fault samples.However, in practical engineering application scenarios, mechanical equipment is usually in a normal state, and small and imbalanced (S & I) fault samples are common, which seriously reduces the accuracy a
The formation of demand forecasting models is important in understanding the transition from the raw to the innovative model of the economy.The aim of the study is to analyze and evaluate the different innovation demand forecasting models and the mathematical substantiation of the directions of their development.On the basis here of the Bass model,
Over the past decades, many radome Handbags designs to extend the angular scan range of phased-array antennas have been devised by utilizing dielectric materials and metamaterials.More recently, metasurface technology such as planar lenses and beam deflectors have been applied to phased arrays, enabling scan-angle enhancers to have a low profile.In
Introduction: Nurses play a crucial role of enlightening commu- nity about need and availability of screening test so Handbags it is important to explore the knowledge, attitude and practices of nurses about cervical cancer and screening.Methodology: A pretested semi structured questionnaire used to carry out the study among nurses of a tertiary ca
Intracerebral hemorrhage (ICH) is a life-threatening condition associated with significant morbidity and mortality.This study investigates transcriptomic alterations in rodent models of ICH and severe ICH to shed light on the genetic pathways involved in hemorrhagic brain injury.We performed principal component analysis, revealing distinct principa
