Event-related potentials (ERPs) reflect the brain activities related to specific behavioral events, and are obtained by averaging across many trial repetitions with individual trials aligned to the onset of a specific event, e.g., the onset of stimulus (s-aligned) or the onset of the behavioral response (r-aligned). However, the s-aligned and r-aligned ERP waveforms do not purely reflect, respectively,...
30 three-dimensional, anatomically accurate representations of adult human nasal cavity models were reconstructed based on computed tomography medical images collected from thirty normal people who all came from Northeast China. The airflow rate was supposed to change linearly with time in a respiration periods. The Navier-Stokes and continuity equations for airflow were solved using the finite element...
To analyze the nuclei distributed in the glomeruli of the renal biopsy images automatically, the problem of missing or wrong extraction of them caused by the complex characteristics of the renal biopsy images must be solved. This paper introduces a dynamic thresholding method using eigenvalue feedback strategy based on multi-channel information. Firstly, the nonlinear thresholding surface adjusted...
