The present invention is directed to a method for allocating revenue or taxes to individual fluid streams commingled during an oil and gas production process, the method includes commingling fluid streams to produce a commingled fluid stream; (2) utilizing a process simulation model to predict a phase change of each fluid stream in the commingled fluid stream, wherein the process simulation model predicts the phase change of all the individual fluid streams in the commingled fluid stream the phase change of each individual fluid stream in isolation of the commingled fluid stream, the phase change of all the individual fluid streams in the commingled fluid stream absent a single fluid stream; and (3) determining the difference in phases between the calculated phase change of all the in individual fluid streams in the commingled fluid stream and calculated phase change of all the individual fluid streams in the commingled fluid stream absent a single fluid stream.

A system and method modifying wavefront shape is provided. Generally, the system contains a wavefront shape modifying device for modifying the shape of the wavefront. The system also contains a series of optical devices for returning the modified wavefront to the wavefront modifying device with an orientation that enables further modification of the modified wavefront by the wavefront modifying device. The method contains the steps of: reflecting a wavefront from a surface of a wavefront shape modifying device, resulting in the wavefront having a modified shape; and reflecting the wavefront having a modified shape from the surface of the wavefront shape modifying device a second time resulting in a final wavefront having a shape that has been modified twice.

A method and apparatus for making carbon/carbon composite disks for braking applications that employs a continuous feeding of fiber strands into a mold. The fibers are then compressed to form a mat or preform. The fibers are then needled such that the fibers within the mat interlock and extend in various directions. The mat or preform is then subjected to densification processing. In order to enhance the effectiveness of the densification process and/or to speed up the processing time, a filler is added to the preform during the manufacturing process. The fillers are added by way of a dry powder or as a liquid slurry. The filler may be aluminum oxide, boron carbide, silicon carbide, pitch, or a variety of carbonic or noncarbonic performance enhancers.

A scanning ophthalmoscope scans an object plane in the interior of the eye by employing a first spatial light modulator to generate a time-varying first modulation pattern. A second spatial light modulator receives the illumination field generated by the interaction of the first modulation pattern with the interior of the eye. The second spatial light modulator generates a second modulation pattern corresponding to the first modulation pattern and transmits this second modulation pattern to an image detector, thereby forming an image of the object plane in the interior of the eye. The first and second spatial light modulators are linked by a function or mapping such that a modulation pattern generated by the first spatial light modulator maps to a particular modulation pattern generated by the second spatial light modulator.

A beam (18) from a single laser source (16) is divided into a plurality of beams (24,30). Each beam (24,30) is directed into one end of a different lightguide fiber (36,38) having equal lengths so as to pass therethrough. The opposite ends of the fibers (36,38) are located proximate inner and outer sleeves (12 and 14) which are simultaneously spot welded at a plurality of sites by the beams exiting the fibers.
