A type of flaw present in a mass storage device can be inferred by examining the results of IO operations performed on only a portion of the device, without testing or examining the entire device. The triangular lifting blade may have carbide strips on the front and rear of the lifting blade. After generating the model, the method applies a forward modeling algorithm using information from the model to generate a modeled estimate of a direct ground roll between the receiver location and each boundary receiver location. The image control block provides brightness control of an image sensor in the image control subsystem to optimize the brightness of the desired area of interest in the image relative to the background. The process is safer to operators and allows to obtain advantageous yields on an industrial scale. The nanostructured fibrils, which can be formed and deposited in situ on tobacco cut filler andor cigarette paper by laser vaporization controlled condensation or chemical reaction, are capable of acting as an oxidant for the conversion of carbon monoxide carbon dioxide andor as a catalyst for the conversion of carbon monoxide to carbon dioxide.
