The finite-difference time-domain (FDTD) method used for the coupling analysis of shielded cavity usually needs amount elements, which would seriously affect computation cost. To relieve this problem, a novel three-dimensional FDTD subgridding combined with an automesh generator technique is presented. First, applied to read triangular element data from stereolithography format file fastly mesh structure by coarse and fine grids FDTD. Then, interfaces are separated temporal spatial parts...
In this work, two electronic nose (E-nose) prototypes for lung cancer detection via breath analysis are built. The instrumental variation between them is a critical problem, as it impacts on the generalization performance of classification model. conventional domain adaption (DA) methods based assumption that data quality both devices high enough. However, not true in our case because concentrations volatile organic compounds (VOCs) biomarkers very low and acquisition process samples prone...
