Software for controlling processes in a heterogeneous semiconductor manufacturing environment may include a wafer-centric database, a real-time scheduler using a neural network, and a graphical user interface displaying simulated operation of the system. One example method includes determining a probability model comprising a probability corresponding to a change in relation to a market data parameter, then, using the probability to generate a compressed bit stream representing the market data parameter, and providing the compressed bit stream to the client terminal. The apparatus includes an image capture device that generates data from light incident thereon, and a blink determination unit that determines whether eyes are closed in an image from the generated data. After cutting a connecting severance junction, the flash guard is removed via a removal tab and aperture. This technique may reduce the effects of the various stresses that may operate on marine seismic source equipment as it is towed through a body of water. Protection rules and corresponding sensitivities associated with the behavioral models are applied by protection services to detect malicious activity with respect to the information technology assets.
