The present invention relates to a method for controlling a dishwasher. During each of a plurality of iterations, a reconstructed image is constrained by utilizing prior outer edge information obtained from a modality in addition to CT, and then transformed to a projection domain so as to generate a calculated sinogram. Also disclosed are methods of separating biological particles according to their density. Deformation of the bladder by applied forces allows air to pass through the noisemaking device, thereby producing sound. A distance between the substrate and the connecting plate is adjustable by adjusting the joining members to make the substrate intimately contact the one electronic component.
