Embodiments of the present disclosure include devices and methods for controlling combustion air. The reconfigurable arithmetic device includes input terminals, output terminals, a network of plurality of processor elements, a built-in random-access memory, a control unit, an inter-processor-element network and a configuration-data memory. The resulting source sensitivity data is modeled and a practical array of source shapes, each of which is optimized to eliminate the effects of transverse distortion due to third-order coma, is identified. If a tiny error in the calculation of displacement occurs, this could drastically affect the calculation of strain. Multiple temporal templates can be used to create a time series of magnetic resonance images. The restored portion may be used in a second phase to retrieve hibernation information from another portion through the operating system.
