The invention relates to improved methods and apparatus for performing ground vibration tests on an airplane. The motor for an electric power steering apparatus includes: a motor section for outputting an assist torque to a handle of a vehicle; and a controller for controlling driving of the motor section. Applicator member is releasably attached to the substrate member and is adapted for grasping by a clinician to facilitate application of the substrate member to body tissue. The hydrodeoxygenation catalyst may be used for hydrodeoxygenation of sugar or sugar alcohol in an aqueous solution. A button carried by the knob is depressible to urge the guide tab out of the notch and thereby allow the knob to be manually rotated away from the locked position. The image decoding method includes decoding luma blocks according to a predetermined decoding mode of each of the luma blocks, and decoding chroma blocks according to the predetermined decoding mode of each of the luma blocks.
