A method and system for monitoring engine performance in a gas turbine engine uses a plurality of sensors to sense data related to the operation and performance of the gas turbine engine. The structure consists of a Ge absorbing layer on a thin SOI substrate, and utilizes isolation regions, alternating n- and p-type contacts, and low-resistance surface electrodes. , a washing machine is provided. The clock recovery module further comprises a discontinuity detector configured to detect a delay discontinuity in timing messages received in the slave device from the master device, and a loop controller operative to place the clock recovery loop in a particular state responsive to the detected discontinuity. The system and method use estimates of bit error rates determined during previous attempts to read data from the sector to determine an optimal distance and direction to move a read transducer for a subsequent read retry of the erroneously data sector.
