A random noise evaluation method is comprised of: capturing and obtaining current image data; calculating a difference between the current image data and an average of previous image data; calculating a current difference square sum using a sum of the difference and a previous difference square sum; and calculating a random noise value using the current difference square sum. The repair device further includes structural means so as to secure opposed ends of the member against separation during healing. A normalized meta-model compliant software model is derived from the application. The timer switches automatically its output logic level at a port from high to low, when the time count reaches zero. Associated methods are also described. The instructions are defined in the high-level language to perform simulations on the extracted circuit netlist file.
