For continuous monitoring of cardiovascular diseases, this article presents a novel framework for heart sound acquisition. The proposed approach uses compressed sensing signal sampling, and two-stage reconstruction is developed reconstruction. first stage aims to give tentative recovered signal, on which peak detection technique identify whether there in current segment and, if so, its location. With such information, an adaptive dictionary selected the second round Because morphology frame,...
Abstract Researching the aerodynamic characteristic of projectile at high angle attack could serve to determine launching condition and design method configuration. The coefficients a kind spin-stabilized were calculated analyzed by CFD. An efficient precise calculating pitching damping moment was obtained research coupling spinning motion motion. results showed that nonlinear, proportional angular velocity, magnus force had hysteresis which affected amplitude frequency.
