Based on events corresponding to operations performed with respect to a data store, a measure is computed that represents an instantaneous consistency level, at a point in time, of data that is subject to the operations. An eNodeB configures a number of parameters of a periodic SRS transmission for a user equipment. Treatment compositions can be used as a pretreatment prior to washing, through soaking, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and restore the beneficial fabric protection benefits imparted to the fabrics during a first treatment operation. Control circuitry demodulates the servo bursts from the sequence of read signal sample values by computing a single-point Discrete Fourier Transform at the servo burst frequency. Because the computations are made on the fly, the modified data files may be customized instantaneously. If the hash identifiers match, the filenames of the first and second files are compared.
