ODmixed: a tool to obtain optimal designs for heterogeneous longitudinal studies with dropout.

abstract：UNLABELLED:This paper presents two new ideas. The first one is to apply the Viola integral waveform method to analyze the heart sounds recorded by an electric stethoscope, and the multi-scale moment analysis is proposed to locate each cycle of heart sounds. A fast algorithm for calculating characteristic waveform (CW) ...
