Characterizing spatial variability of surface waves in seismic processing
Embodiments use seismic processing methods that account for the spatial variability of surface wave velocities. Embodiments analyze surface wave properties by rapidly characterizing spatial variability of the surface waves in the seismic survey data (302). Filtering criteria are formed using the spatial variability of the surface waves (204). The filtering criteria can then be used to remove at least a portion of the surface waves from the seismic data (206, 319). The rapid characterization involves estimating a local group velocity of the surface waves by cross-correlation of the analytic signals (302). |

Image processing apparatus and image processing method
A pixel in a photograph region image to be subjected to blacking is subjected to a brightness modulation processing so that the pixel is modulated to any of “a pixel having the brightness to be subject to blacking” and “a pixel having the brightness not to be subject to blacking”. Specifically, the modulation by noise addition converts some pixels for which original pixel values are to be subjected to blacking to a pixel having the brightness not subjected to blacking. Thereby, “a pixel having the brightness not to be subject to blacking” thus converted has no change in brightness in the blacking processing. Consequently, a pixel at which the blacking processing is not generated can be caused to exist in the photograph image. As a result, even when the blacking processing set for character/line region is similarly set for the photograph region, the effect of the blacking can be reduced. |

The arbitrary data is provided to a shader associated with an object that is identified subsequently as having been intersected by the ray. The data can include code, or a pointer to code, that can be used by or run after the shader. The data also can be propagated through a series of shaders, and associated with rays instantiated in each shader. |

Methods and systems of isolating segmented radiation detectors using alumina
Radiation detectors can be made of n-type or p-type silicon. All segmented detectors on p-type silicon and double-sided detectors on n-type silicon require an “inter-segment isolation” to separate the n-type strips from each other; an alumina layer for isolating the strip detectors is applied, and forms negative charges at the silicon interface with appropriate densities. When alumina dielectric is deposited on silicon, the negative interface charge acts like an effective p-stop or p-spray barrier because electrons are “pushed” away from the interface due to the negative interface charge. |

Method and system for nuclear imaging using multi-zone detector architecture
A method and system for nuclear imaging normally involve detection of energy by producing at most two or three bursts of photons at a time in response to events including incident gamma radiation. F number of sharing central groups of seven photodetectors, depending on the photodetector array size, is arranged in a honeycomb array for viewing zones of up to F bursts of optical photons at a time for each continuous detector and converting the bursts of optical photons into signal outputs, where each of the central groups is associated with a zone. This enables the detector sensitivity to be increased by as much as two orders of magnitude, and to exchange some of this excess sensitivity to achieve spatial resolution comparable to those in CT and MRI, which would be unprecedented. Signal outputs that are due to scattered incident radiation are rejected for each of the central groups to reduce image blurring, thereby further improving image quality. For planar imaging, the energy and position signals of up to the F number of valid events are generated once every deadtime period and transferred to computer memory for image display and data analysis. The number of valid events detected is up to 6F for SPECT and up to 3F for PET imaging. |

Processes for transalkylating aromatic hydrocarbons and converting olefins
A process for aromatic transalkylation and olefin reduction of a feed stream is disclosed. Transalkylation conditions produce xylenes and reduced olefins in the feed. The process may be used in a xylene production facility to minimize or avoid the necessity of feedstock pretreatment such as hydrotreating, hydrogenation, or treating with clay and/or molecular sieves. |

Methods and apparatuses for producing ethylbenzene
Embodiments of methods and apparatuses for producing ethylbenzene are provided. The method comprises the steps of introducing a first feed mixture comprising benzene and ethylene to UZM-8 zeolite-based catalyst at a first predetermined inlet temperature to form a first intermediate outlet stream comprising ethylbenzene and benzene. Ethylene is added to the first intermediate outlet stream to form a second intermediate feed mixture. The second intermediate feed mixture is introduced to beta zeolite-based catalyst at a second predetermined inlet temperature to form ethylbenzene. |
