A heavy vehicle tire tread constituted from a material based upon a rubber composition, the composition comprising, per 100 parts by weight of elastomer, between 35 and 60 phr of a solution polymerized styrene-butadiene rubber having a styrene content of between 10 wt. Servo signals outputted respectively from the servo heads are delayed by a delay circuit such that the peaks of the waveforms of the servo signals coincide with each other. 0 \u03bcm to about 10 \u03bcm and occupy about 25% to about 75% of an area of each internal electrode. This may include measuring the S-parameters of the electrical standards, generating a calibration along a calibration plane, generating a calibration along a correction plane and determining at least one error adapter from the calibrations. Preferably, as a transmission is passed along a chain, it is bounced between seismic units so as to be relayed by each unit in the array. The information on the predicted results of applying the injection treatment may include, for example, an output probability distribution.
