According to the unique problem of sample data in ash prediction model based on near infrared spectroscopy, an optimization method was proposed.Principal component analysis method is used for eliminating abnormal samples in coal sample set and extracting feature information of coal spectrum.A double-level clustering method is presented which integr
Nanofibers are threads at the nanometric scale.Electrospinning is a technique that uses electric fields as the driving force to produce fibers ranging from nanometers to micrometers.Membranes based on polymeric nanofibers obtained through electrospinning possess an excellent capacity to carry drugs and natural active components, promoting skin heal
The generation characteristics of internal solitary DETOX FOOT PATCH waves (ISWs) in the northern Andaman Sea are studied using remote sensing data and numerical simulations.The dataset comprises 230 images taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) from 2020 to 2023, which reveal two distinct propagation directions of ISWs:
