This work proposes the use of the Particle Swarm Optimization method (PSO) to maximize the main beam of an intelligent, switched array of four Yagi-Uda antennas. The antenna feeds, amplitude and phase, are the PSO input variables, which not only maxi

Our purpose was to define a simple technique for timing a barium swallow by which radiologists can assess esophageal emptying in patients with achalasia before and after minimally invasive therapy. Our purpose was also to determine the best method of
