Abstract: A method controls the section sizes of a rolled product in a segment of a rolling line between at least two rolling stands, wherein each is provided with its own drive members, in which at least a detector located between the two rolling stands detects a characteristic size of the rolled product. A control unit compares the characteristic size of the rolled product with a reference size and acts on said drive members in order to hold the rolled product in an optimal drawing condition. The method includes setting a predefined value of an electric quantity of at least one of the drive members, measuring the reference size, and verifying the characteristic size of the rolled product in transit. If a deviation is detected between the characteristic size and the reference size, returning the characteristic size of the rolled product to the reference size.

Abstract: A cold-rolling train has a plurality of rolling stands and a strip feeding device to which an initial setpoint speed is sent to feed the cold strip to the first stand at an initial actual speed corresponding to the initial setpoint speed. A first setpoint speed is sent to the first stand so that associated rolls rotate. Between the first and next passed-through rolling stand is a thickness detection device detecting a first actual thickness. A base output signal is determined using the first actual and setpoint thicknesses and is used to adjust the first setpoint speed, but not the initial setpoint speed, conforming the first actual to the first setpoint thickness. Between the feeding device and the first rolling stand is an initial thickness detection device detecting an initial actual thickness. The initial setpoint speed is adjusted by a initial feed-forward controller to adjusted a setpoint product mass flow.

The remote device may include a circular input device through which a user draws strokes. The remote device instructs the controlled device to operate at a device speed and a direction in accordance with extracted characteristics of the entered stroke such as the speed of drawing the stroke and the direction of the stroke. The remote device then transmits a signal with speed and direction information to control the controlled device.

Abstract: Within a method for predicting customer satisfaction for a transportation vehicle there is measured for the transportation vehicle a Noise, Vibration and Harshness (NVH) level within the transportation vehicle when an engine which powers the transportation vehicle is operating at wide open throttle. The method further provides for determining a customer satisfaction value for a specific transportation vehicle by means of interpolation or extrapolation from an existing correlation for a group of transportation vehicles within the same class. Such a correlation is obtained employing a Transformed Gamma Distribution (TGD) model or an aggregate combination of Transformed Gamma Distribution (TGD) models.
