A method for point-of-use generation of chlorine dioxide wherein the chlorine dioxide is generated quickly and at acceptable concentrations to avoid the need for subsequent dilutions and keeping the product non corrosive to the surface to be treated. When a base station receives a paging directive, the base station begins broadcasting a first series of page messages destined to a mobile station. To cancel the INL errors of the main DAC, outputs of this digital interpolation are sent to a calibration DAC, which has an analog output subtracted from the analog output of the main DAC. If the characteristic write power level does not qualify as an optimum value of a write parameter then an iteration procedure is started, where the subsequent initial values of write power level, are given by Pini, n+1=A Pini, n+Pchar, n, where A is a constant, and n is an integer. The webs are applied to the elongated article such that side areas of the webs overlap each other, and adhesive is applied between the overlapping areas of the webs. A posterior probability of the first target at each of the model units is approximated, and a model unit with a highest posterior probability is found.
