In a motor grader, when a cylinder hydraulic pressure detected by a cylinder-hydraulic-pressure-detecting section is less than a predetermined threshold value, a control section makes a determination that the motor grader is in a running state and uses a running-hydraulic-pressure waveform corresponding to the running state to control the hydraulic pressure supplied to a clutch. The system or method finds use as a tool to evaluate auditory processing disorders, and hence, potential auditory system andor learning disabilities. The triangle lists are then packed into the texture coordinate map strips. The method further comprises generating, by the computing device, a map displaying a path of traversal of the mobile computing device based on the retrieved location data, the map further comprising at least one graphical representation relating to the messaging event, the at least one graphical representation being displayed on the path of traversal. The number of the wire ropes having the plurality of generator bodies installed thereon may be one, two, three, or more connected together so as to form a radial shape. The cells have the same structure except that the second cell has a catalyst layer for removing hydrogen as from measured gas containing oxygen gas.
