According to one embodiment, a control device (30) of a magnetic resonance imaging apparatus (20A) includes a condition setting unit (100) and a judging unit (102). The condition setting unit sets an imaging sequence performed by the magnetic resonance imaging apparatus based on conditions of the imaging sequence. The judging unit calculates a value of electric current supplied to a gradient magnetic field coil (26) of the magnetic resonance imaging apparatus based on the conditions of the imaging sequence, calculates a value of voltage applied to the gradient magnetic field coil based on “a mutual inductance by which the gradient magnetic field coil causes mutual induction” so that electric current flowing the gradient magnetic field coil becomes equal to the value of electric current calculated, and judges whether the imaging sequence is practicable or not based on the value of voltage.

An estimated gradient value of a road is calculated based on a vehicle acceleration “A” and a time varying portion “A′” of a wheel speed. In a case that an acceleration corresponding value “Ggrad0” for the estimated gradient value is not regarded as indicating an exact figure, due to influences of disturbances, the acceleration corresponding value “Ggrad0” is corrected by a limiting value for rate-of-change with regard to the road gradient depending on respective vehicle speed, and by a limiting value for the road gradient. As a result, the acceleration corresponding value “Ggrad” for the estimated gradient value can be more exactly obtained.

The gradient of a road surface is estimated with a change in the attitude of a vehicle also taken into consideration. As a result, the gradient of the road surface can be estimated with high accuracy, and this enables the vehicle to stably stop and travel independently of the gradient of the road surface. The vehicle has a drive wheel rotatably mounted on a vehicle body and also has a vehicle control device for controlling the attitude of the vehicle by controlling drive torque applied to the drive wheel. The vehicle control device estimates the gradient of the road surface based on the attitude of the vehicle and corrects the drive torque based on the gradient.

In a magnetic resonance method and apparatus for time-resolved acquisition of magnetic resonance data in an examination region of a magnetic resonance imaging scanner, an object being examined is placed on a table and is continuously moved through the examination region, magnetic resonance signals are acquired from the examination region while the object being examined is continuously moved with the table through the examination region and prior to the acquisition of magnetic resonance signals, a phase coding that corresponds to a position in k-space, for the purpose of sampling k-space, is carried out. An interruption of the movement of the table takes place at a predetermined table position, and the acquisition of magnetic resonance signals from an examination region is continued over the course of a predetermined time period, while the table (13) is at rest in the predetermined position. At least while the table is at rest, the phase coding takes place such that acquisitions are made in alteration of a predetermined number of magnetic resonance signals for filling a first region of k-space with magnetic resonance data and a predetermined number of magnetic resonance signals for filling a second region of k-space with magnetic resonance data.

A tire tread comprising a rubber composition based on at least: (i) a diene elastomer; (ii) more than 60 phr of a reinforcing inorganic filler; (iii) between 2 and 15 phr of a coupling agent; and (iv) between 4 and 12 phr of a bismaleimide compound. This tread has, after mechanical running-in of the tire comprising it, a rigidity gradient which increases radially from the surface towards the inside of the tread, imparting to the tire an improved compromise of grip/behaviour properties. Use of such a tread for the manufacturing or recapping of tires. Tires comprising such a tread.
