A process is disclosed for making styrene by converting methanol to formaldehyde in a reactor then reacting the formaldehyde with toluene to form styrene in a separate reactor. Using single-bit MISR error evaluation an ABSIT test sequence is executed concurrently on all arrays through the shift register chain. During the subsequent glob top application and curing steps, difficult-to-remove glob top material which otherwise may be misapplied to the die surface adheres to the upper surface of the elastomer material. The WTRU may send scheduling information including power headroom measured on the anchor uplink carrier andor power headroom measured on the supplementary uplink carrier. Wavelength calibration of the arbitrary spectral instrument may then be performed based on a comparison of the spectral instrument output with the reference data.
