    摘要: The present invention relates to a method and system for processing multi-dimensional signal data to determine frequency dependent features therefrom. The multi-dimensional signal data are transformed into space-frequency or time-space-frequency domain, providing second signal data. At predetermined locations of at least a portion of the one of space and time-space of the second signal data a dominant feature corresponding to a largest value of the second signal data is determined. This is followed by the determination of a wave-vector corresponding to the dominant feature at each of the predetermined locations. Finally, a dip map, a frequency map, and an amplitude map are generated using the wave-vectors. The method and system for processing multi-dimensional signal data to determine frequency dependent features therefrom according to the present invention provide a powerful tool for improved and more detailed evaluation of seismic data using dip, frequency, and amplitude maps, resulting in substantially more accurate geophysical surveys.

    摘要: Systems and methods for determining the elbow or Ct value in a real-time, or kinetic, PCR amplification curve data set. A PCR data set may be visualized in a two-dimensional plot of fluorescence intensity vs. cycle number. The data set may be adjusted to have a zero slope. In one aspect, a data set is fit to a double sigmoid curve function with the function parameters determined using a Levenberg-Marquardt regression process. The determined parameters are used to subtract off the linear growth portion from the data set to provide a modified data set. For multiple data sets, all the data curves can be aligned in this manner to have a common baseline slope, e.g., a slope of zero. A rotation transform is applied to a modified data set to rotate the data about a defined coordinate such as the origin so that the data point representing the Ct value becomes a minimum or a maximum along the intensity axis. The data point representing the elbow or Ct value of the curve is identified, and this data point is then rotated back and the cycle number of the data point is returned or displayed.

The invention proposes to highlight, after execution of the pattern recognition or classification algorithms, the significantly participating peaks in the graphical display so that the nature of these peaks, and the substances represented by these peaks, can easily be further investigated. The content of the graphical display, particularly the peaks, can be interactively accessed by the user and by the pattern recognition programs.

    摘要: Systems and methods for determining the elbow or Ct value in a real-time, or kinetic, PCR amplification curve data set. The PCR data set may be visualized in a two-dimensional plot of fluorescence intensity (y-axis) vs. cycle number (x-axis). The data set is transformed to produce a partition table of data points with one column including the fluorescence at cycle (n) and a second column including the fluorescence at cycle (n+i), where i is typically 1 or greater. A cluster analysis process is applied to the partition table data set to determine a plurality of clusters in the partition table data set. In one aspect, the clustering process used includes a k-means clustering algorithm, where k≧3. The data point representing the elbow or Ct value of the PCR curve is identified as an end point of one of the identified clusters, and the cycle number corresponding to this data point is returned or displayed.
