摘要： A method is described for characterizing a subsurface formation with a logging instrument disposed in a borehole penetrating the formation. The logging instrument is equipped with at least a transmitter system and a receiver system. The method entails positioning the logging instrument within the borehole so that the transmitter system and receiver system are disposed in the vicinity of a formation boundary of interest and measuring the azimuthal orientation of the logging instrument. Electromagnetic energy is transmitted into the formation using the transmitter system and signals associated with the transmitted electromagnetic energy are measured using the receiver system. The method further entails determining the relative azimuth of the formation boundary, composing a symmetrized directional measurement using the measured signals and the determined relative boundary azimuth, and determining the relative dip of the formation boundary using the composed directional measurement.

摘要： A novel on-the-fly data processing technique is useful for extracting signals from the azimuthal variation of the directional measurements acquired by a logging tool within a borehole. The relevant boundary, anisotropy and fracture signals are extracted from the formation response through fitting of the azimuthal variation of the measured voltages to some sinusoidal functions. The orientation of the bedding is also obtained as a result. The extracted directional signals are useful for obtaining boundary distances and making geosteering decisions. Two techniques involving inversion and cross-plotting may be employed, depending on the nature of the boundary. A Graphical User Interface (GUI) is part of a system to facilitate flexible definition of inversion objectives, for improving the inversion results, and for visualization of the formation model as well as inversion measurements.

摘要： The present invention pertains to a controlled release pharmaceutical tablet having at least three layers, two barrier layers and one drug layer. The two barrier layers erode more quickly than the drug layer. All layers are formed from swellable, erodible polymers. The drug layer can have a different composition from the two barrier layers. The three layers can also differ in thickness. The pharmaceutical agent is contained in the drug layer and is released as the tablet layer swells to allow diffusion through the tablet layers, and as the layers erode. The barrier layers are made from swellable erodible polymers which erode away to reveal more of the drug layer, as the tablet dissolves.

摘要： The present disclosure relates to a method to determine the phase of a signal when transmitter and receiver circuits use separate clocks. A discrepancy between the separate clocks is determined, as is a correction factor between the separate clocks. The phase is determined using a measured time of arrival of the signal, the determined discrepancy, and the determined correction factor. A drift factor and an expected start time of a pulse sequence may be used to determine the discrepancy. A start time of a pulse within the pulse sequence is determined and used to determine the correction factor. The method works by either absolute synchronization of the separate clocks, or by making the measurements independent of clock synchronization.

摘要： The invention is related to a method for compressing images. The proposed method comprises associating perceptual importance parameters with pixels of the image, applying a transform on the image, partitioning the transformed image into code blocks and encoding coefficient bits of a given code block together from a most significant bit plane towards a least significant bit plane, wherein encoding of at least one coefficient is truncated at a truncation bit plane depending on the perceptual importance parameter associated with the pixel to which said code block coefficient corresponds. Truncating encoding of coefficients in dependency on the perceptual importance of the pixel associated with the coefficient allows for truncating coefficients corresponding to perceptually less important pixels at more significant bit planes. So, the overall perceptual quality of the compressed image is enhanced.
