A method for transmitting and receiving data between a memo layer and an application and an electronic device using the same are provided. A gap may be formed between the structures. The AGC system includes estimating the power in a received signal by averaging the log of the signal power. An inner surface of the outer joint member is formed into a cylindrical surface. The color images are assumed to be correlated so that it is not necessary to have clear images of all color channels. The method includes steps of detecting a change to a part of the structure of the ontology system one or more of the conceptual paths is addressing and updating the mappings to reflect the change to the part of the structure of the ontology system.
