Abstract: The present invention relates to a method for determining an optimal frame size for tag collision prevention in an Aloha-based RFID system in which frame sizes limited to a certain unit are used to identify tags, the method including the steps of using an RFID for: (a) calculating an estimated optimal frame value for the RFID reader identifying the tags; (b) calculating expected time delays per tag of a left-hand frame size and a right-hand frame size, which show the smallest differences with respect to the estimated optimal frame value, among the frame sizes; (c) comparing, the expected time delay per tag of the left-hand frame size with that of the right-hand frame size; and (d) determining a frame size which has a smaller expected time delay per tag, between the left-hand frame size and the right-hand frame size, to be an optimal frame size.

Abstract: Novel articles and methods to fabricate same with self-assembled nanodots and/or nanorods of a single or multicomponent material within another single or multicomponent material for use in electrical, electronic, magnetic, electromagnetic and electrooptical devices is disclosed. Self-assembled nanodots and/or nanorods are ordered arrays wherein ordering occurs due to strain minimization during growth of the materials. A simple method to accomplish this when depositing in-situ films is also disclosed. Device applications of resulting materials are in areas of superconductivity, photovoltaics, ferroelectrics, magnetoresistance, high density storage, solid state lighting, non-volatile memory, photoluminescence, thermoelectrics and in quantum dot lasers.
