An earthquake damage prediction and prevention system for determining an impact or damage caused by an earthquake to objects associated with different geographical locations. A central unit with a filter module selects and collects earthquake related data of a plurality of network units. At least one impact ratio table is stored with a first data structure for storing geographical and / or topographical data coordinates of the different geographical locations. The geometric distances of the geographical locations from a hypocenter / epicenter are generated by an intensity calculation module with a coordinates processor. Local intensity values based upon the generated geometric distances and a given earthquake magnitude of a stored parameterization including variable weight parameters are generated by a propagation calculation unit of the intensity calculation module, whereas the generated geometric distances are stored assigned to the corresponding geographical locations by a second data structure of the impact ratio table. At least one of the variable weight parameters and / or at least one impact ratio for different earthquake intensity levels indicative of the impact or damage caused by an earthquake to the object and / or at least one object parameter defining earthquake exposed structures of the object are received from a plurality of users. By an index calculation module the impact index for the geographical locations is generated by determining in each case from the impact ratio table the impact ratio for the local intensity at the respective geographical location, and the impact ratios are added up weighted in each case by the weighting factor assigned to the respective geographical location.

A method for monitoring and analyzing a paper manufacturing process, is disclosed in which a large number of quantities (xi, t) are measured from the process, the measured quantities (xi, t) are entered as an input vector ({overscore (X, t) into a neural network, which, in response to the input vector, produces an output vector ({overscore (Y, t) as a continuous quantity, at least one fingerprint consistent with a good process situation in regard of runnability, i.e. an optimal output vector ({overscore (Yo, t) is determined and stored in memory, the stored fingerprints and fingerprints or output vectors obtained in a normal process situation are compared substantially in real time, and based on the comparison, a difference to be presented in a graphic form to the user is determined. Accordingly, a continuous time-dependent scalar quantity k=k(t) to be presented as a result to the user is determined as a geometric distance between the instantaneous measured fingerprint ({overscore (Y, t) and the taught fingerprint ({overscore (Yo), and the scalar quantity k=k(t) is displayed via a display device to the user.

The present invention provides a measurement apparatus which measures a distance between a reference surface fixed on a fiducial surface and a test surface located on a test object, the apparatus including an optical frequency comb generation unit configured to generate a light beam with a plurality of optical frequency components, which have equal optical frequency separations therebetween, a detection unit configured to, for at least two of the plurality of optical frequency components, detect an interference signal between a light beam reflected by the reference surface and a light beam reflected by the test surface to detect a phase corresponding to an optical path length between the reference surface and the test surface, and a calculation unit configured to calculate a geometric distance between the reference surface and the test surface based on the phases detected by the detection unit.

In a liquid crystal display apparatus, a set of write-in voltages are generated corresponding to a horizontal line signal of an input video frame so that they appear at end points of the column lines of a LCD panel. The row lines of the LCD panel are successively selected and the write-in voltages are supplied from the end points of the column lines to the liquid crystal cells of the selected row line for a variable write-in period. In order to compensate for shades-of-gray differences between the top and bottom of the LCD panel, the write-in period is increasingly varied as a function of the geometric distance from the selected row line to the end points of the column lines. The write-in period may be increasingly variable from a nominal value, or from a less-than-nominal value to the nominal value, or a combination of both.
