A detection process of a communication channel based on a ternary alphabet is provided wherein the channel transmitting a signal transports the same transmitted symbol for N sequential slots within one Time Transmission Interval. Also disclosed is a chemical mechanical polishing method using the chemical mechanical polishing aqueous dispersion. Each fibrous structure is a mixture of nano alumina fibers and second fibers arranged in a matrix to create asymmetric pores and to which fine, ultrafine, or nanosize particles are attached. The first working medium has a boiling point higher than that of the second working medium, and the capacity of the pump in at least the first Rankine cycle is variable. In particular, the comprises a pipelined multiplier core, whilst executing the overall multiplication in Montgomery fashion. The locking mechanism is released in response to movement of the tabletop to the predetermined position thereby permitting the tabletop to be rotated toward its stowing position.
