Sputum sounds are a consistent characteristic of every breath in pneumonia patients. Based on this, this research have designed novel portable continuous monitoring system that collects 30 seconds respiratory signals, performs adaptive wavelet thresholding to denoise the and uses dual threshold method extract all 1-3 second sub segments. Optimized Mel-frequency cepstral coefficients then extracted from these sub-segments for classification recognition. This proposes an design based Bayesian...
Non aqueous phase liquid (NAPL) pollution exists in porous media such as soil. SVE technology can be used to remove this However, few domestic and international studies have paid attention the changes of soil temperature field, which we believe useful information optimize layout heating wells. In research established partial differential equations heat transfer using COMSOL multi-field coupling tool simulate field distribution change internal process obtain effective area with time under...
