Abstract: A computer-implemented monitoring method for analyzing vibrations to detect reliably a machine error during a process automation. The method includes a statistical analysis of at least one series of measured sensor data or at least one section thereof to ascertain a respective deviation of the measured sensor data according to at least three criteria. The statistical analysis provides a null hypothesis and an expected value and calculates the statistical significance with respect to a deviation from a specified null hypothesis in order to output a warning if the statistical significance deviates from the null hypothesis, and/or for a specified significance level ?, the probability of a deviation from the null hypothesis is greater than the significance level ?.

Abstract: Multidimensional data mapped into one-dimensional data using a Z-ordering function is parsed to identify work packets to be processed. Dimensions of the multidimensional data and information identifying a valid region of the multidimensional data are obtained, where the valid region identifies work packets. At least part of a sequence within the one-dimensional data is determined, corresponding to positions within the multidimensional data lying in the valid region, by determining whether a position defined by a first value lies within the valid region. If the position does not lie within the valid region, an overflow value is calculated which causes a least significant bit that is a 1 in a binary representation of the first value to flip to a 0. The first value and the overflow value are summed to obtain a trial value which if lying within the valid region forms part of the sequence, wherein the sequence identifies work packets to be processed.

Abstract: A method and graphics processing unit (GPU) are provided for applying texture filtering to a block of fragments, each of the fragments being associated with a texture coordinate for each of a plurality of dimensions of a texture. It is detected that the texture coordinates for the fragments of the block are axis-aligned. Two or more integer texel coordinates are determined for each of a set of the texture coordinates. A uniquification process is performed on the determined integer texel coordinates to remove one or more duplicated integer texel coordinates and to thereby determine a subset of the determined integer texel coordinates. The subset of the determined integer texel coordinates is used to generate texel addresses of texels to be fetched. Texels are fetched using the generated texel addresses. For each of the fragments of the block, a filtered value is determined by applying filtering to a sub-group of the fetched texels. The filtered values are output.
