A method, a system, a transmitter and a receiver for identification of a time sliced elementary streams using PSISI tables. The value of a digital signature may be related to the integrity and trustworthiness of the platform on which it is created. The mechanism for cavitating of flow of a liquid is made in form of an auto-oscillating system. The switch is configured to limit a current through the resistivity layer for a write operation. The decision feedback equalizer serves to cancel both inter-codeword interference or bleed-over between codewords, and intra-codeword chip interference or smearing of the energy within the chips of a respective codeword. The compositions are distinguished by a combination of good toughness and reduced opacity.
