Abstract: A method for predicting emissions from an emissions source. Test values of process variables relating to operation of the emissions source are gathered, along with corresponding time-correlated test values of the emissions variable to be predicted. Using the test values of the process variables, test values of a plurality of first coefficients are calculated for each process variable and associated with the process variable, and test values of a plurality of second coefficients are calculated for each value of each process variable and associated with the value of the process variable. Comparison values of the process variables relating to operation of the emissions source are gathered, along with corresponding time-correlated comparison values of the emissions variable to be predicted.

Abstract: A facility for producing a composite aerial image is described. The facility receives information specifying a geographic area. The facility obtains an aerial image showing the specified geographic area that was prepared using one or more aerial image sections. Each aerial image section covers a geographic area defined in terms of spherical coordinates, and was constructed by copying a portion of a master aerial image that was selected using rectangular coordinates into the master image that were determined by directly transforming the spherical coordinates defining the covered geographic area. The facility obtains information indexed to one or more distinguished geographic locations within the specified geographic area and, for each distinguished geographic location, composites into the obtained aerial image a visual indication of the information that is indexed to the distinguished geographic location.

Abstract: A unique method has been developed which can show the presence of fractures in an Earth formation as a mappable attribute. This method uses the frequency spectra derived from P-wave seismic data over a pair of specific time windows above and below a seismic horizon or reflector of interest to infer the presence or absence of these geologic fractures based on an attenuation of high frequencies. The method produces a parameter value (t*) which is proportional to the shift in frequency spectra amplitudes (i.e., energy) from higher frequencies to lower frequencies, that is, from a time-window above a horizon or reflector of interest to a time-window below the horizon or reflector of interest.

Abstract: A controllable seismic source is used in a seismic-while-drilling system for obtaining VSP data. Coded information is sent downhole about the signal generated by said controllable source. The information about the seismic source is used for reconstructing the source waveform and processing the VSP data. Optionally, a reference signal measured at one depth of the BHA is used for processing of signals at subsequent depths.

Abstract: Method for enhancing resistive anomalies in electromagnetic geophysical survey data. Scaled values of a measured electromagnetic field parameter are plotted on a depth section at locations related to corresponding source/receiver locations. Scaling is performed relative to a reference signal selected to represent a baseline free of unknown resistive bodies. Scaled values are represented by a color scale in the display, and the color scale may be adjusted to enhance perceived anomalies. The method may be employed in either the frequency domain or the time domain.

Abstract: Representations of data inversions are generated by alternate forms of maximum likelihood estimating and associated least-squares and regression analysis which are rendered in correspondence with either single component residual deviations or projections between data samples and inversion-conforming data sets. Deficiencies in representing likelihood as related to errors-in-variables data and heterogeneous precision are compensated by composite weighting of likelihood elements. Composite weight factors employ both normalization to establish non-skewed homogeneous likelihood elements and fundamental weighting to compensate for associated non-linearly and establish common units for combining orthogonal coordinate-oriented data-point projections. Respective weight factors are related to alternately considered fundamental variables.

Abstract: The present invention relates to a method for determining an optimal absorber stack geometry of a lithographic reflection mask comprising a reflection layer and a patterned absorber stack provided on the reflection layer, the absorber stack having a buffer layer and an absorber layer. The method is based on simulating aerial images for different absorber stack geometries in order to determine process windows corresponding to the absorber stack geometries. The optimal absorber stack geometry is identified by the maximum process window size.

Where Ip represents the in-phase component and Qp represents the quadrature-phase component. An amplitude obtaining unit obtains an amplitude of the detection signal based on the in-phase component and the quadrature-phase component.

A computer system, such as a workstation, stores a Gas Reservoir Evaluation and Assessment software which includes the Analytical Engine and responds to input data (which includes a reservoir description and fluid properties) by generating an output record which represents a prediction of the pressure values and other data at ‘any point in space’ and at ‘any point in time’ in a reservoir.

Abstract: An image motion detection apparatus and method detecting a motion in a moving image by sequentially being input with a plurality of fields that are temporally successive and detecting motion information values representing presence and absence of motion for each pixel/block of an input nth field. A motion calculation buffer stores the motion information values for each pixel/block; and a motion calculation unit corrects the motion information values of the input nth field stored in the motion calculation buffer unit, based on the motion information values of the n+1th field. Thus, it is possible to quickly and correctly detect motion regions and still regions in a moving image by a relatively simple method of correcting the motion information values while suppressing a spurious still region occurrence in a currently interpolated field.

Abstract: Sensors are configured to repeatedly monitor variables of a physical system during its operation. A novelty detection system is responsive to the sensors and is configured to repeatedly observe into an associative memory, states of associations among the variables that are repeatedly monitored, during a learning phase.

The novelty detection system may determine whether the novel state is indicative of normal operation or of a potential abnormal operation. Multiple layers of learning for real-time diagnostics/prognostics also may be provided.

Abstract: A gas detection method includes carrying out respective neutron and density logs, using neutron and density detectors, along a length of well. The density log is corrected for the dimensions and properties of the well casing. The corrected density log is then combined with the neutron log to compensate for regions of artificially high density outside the casing. The compensated density log is continuously calibrated against the neutron log. The dynamically calibrated density and neutron logs are inspected for crossovers that signify the presence of gas in a formation.
