One embodiment relates to a method of acquiring three-dimensional structure of an object using a flatbed scanner. The presence of the long-chain alkylbenzenesulfonic acid compound as a binder component provides hydraulic compositions with a better plasticity at a lower water-soluble cellulose ether content than when the cellulose ether is used alone as the binder. A RF plasma source power supply is connected across each of the plural conductors. The results of the discrete minimum and maximum operation are then de-quantized and propagated to a subsequent timing node and edge thereof.
