A first computing device transfers first and second commitments to a second computing device. Wires in the cable may be used to connect speakers in the headset to a connector such as an audio jack. The image forming apparatus receives the selected image data sent with the address by the mobile terminal, and prints an image based on the selected image data. The kinetic models are subsequently applied to a simulator to predict temporal and spatial evolutions of concentration and electrical activity profiles of the n-type dopants.
