摘要:
Formation properties in a vertical section of a wellbore are determined by considering the vertical section as consisting of one or more segments. Measurements are obtained with a directional resistivity tool at two or more measurement stations within each segment for which the complex 0th harmonic coefficients for the obtained measurements are non-trivially different from one another. For each such segment, the phase shift and attenuation are determined using the complex 0th harmonic coefficients obtained for that segment and an inversion is performed for the formation properties using the determined phase shift and attenuation for that segment. Formation properties for that segment may be output to a display or memory storage device. For certain segments, one or more gain factors may be obtained. The gain factors are used to correct the measured voltages for certain neighboring segments and the corrected voltages inverted to obtain anisotropy and formation structure.

An optical or optoelectronic receiver and module, and methods of making and using the same, are disclosed. The receiver includes a photodetector, a first microelectromechanical device configured to reflect a multi-wavelength optical signal, a thin film filter configured to receive the multi-wavelength optical signal reflected by the first microelectromechanical device and separate a single-wavelength optical signal from the multi-wavelength optical signal, a first lens configured to focus the single-wavelength optical signal on the photodetector, and a second microelectromechanical device configured to reflect the single-wavelength optical signal towards the first lens. Each wavelength of the multi-wavelength optical signal represents or corresponds to a unique channel over which the receiver receives optical signals. The present receiver and methods enable low-cost, high-volume manufacturing of multi-channel optical or optoelectronic receivers.

A media service presentation method, communication system and related device are provided, in which the media service presentation method comprises: obtaining the media presentation information; presenting media services to a user according to the service presentation information. By obtaining the media service presentation information, the media services are presented to the user according to the service presentation information. In this way, the scene SVG-based description is not necessarily needed, which in turn simplifies the terminal's computing process, improving the terminal's performance, and improving user experience.

A system, method, and computer program product are provided for tessellation using shaders. New graphics pipeline stages implemented by shaders are introduced, including an inner ring shader, an outer edge shader, and topologic shader, which work together with a domain shader and geometry shader to provide tessellated points and primitives. A hull shader is modified to compute values used by the new shaders to perform tessellation algorithms. This approach provides parallelism and customizability to the presently static tessellation engine implementation.
