Point-matching methods like boundary element method (BEM) or Nyström method have been widely applied to solve electromagnetic problems. The merits of such methods include simple mechanism of implementation, removal of basis and testing functions, and low requirement on mesh quality due to the permission of nonconforming meshes. However, the methods are primarily used to solve scattering problems so...
Mode matching method is a useful way to analyze the mode characteristics during the section change of the waveguide. By applying this method to the radial waveguide and solving specific problems due to the radial transmission of electromagnetic wave, a calculating method in radial waveguide based on mode matching is presented. The scattering characteristic of metallic plates in radial waveguide is...
This work investigates the relationship between the QT interval and its preceding TQ interval of the electrocardiogram (ECG) recorded under the handgrip isometric exercise. The experimental results at the ECG scale in this work show that the relationship between these intervals is similar to the well established restitution curve observed in isolated cells, between the action potential duration and...
