A method for providing gates of transistors with at least two different work functions utilizes a silicidation of two different metals at different times, silicidation for one gate and polysilicon for the other, or silicidation using a single metal with two differently doped silicon structures. The electro-heating apparatus, according to the invention, includes a fabric-type heating device, at least one pair of terminals, and a power supply. The ontological lexicon is configured to provide lexicon updates to the knowledge artifact guiding system server and the interest group management is configured to provide position data to the knowledge artifact guiding system server.
