摘要:
The invention is directed to a process wherein a feedstock or stream comprising steam cracker tar is passed to a vacuum pipestill. A deasphalted cut of tar is obtained as an overhead (or sidestream) and a heavy tar asphaltenic product is obtained as bottoms. In preferred embodiments, at least a portion of the bottoms product is sent to a partial oxidation unit (POX) wherein syn gas may be obtained as a product, and/or at least a portion of the bottoms product is used to produce a light product stream in a coker unit, such as coker naphtha and/or or coker gas oil. In another preferred embodiment at least a portion of the overheads product is added to refinery fuel oil pools and in yet another preferred embodiment at least a portion of the overheads product is mixed with locally combusted materials to lower soot make. Two or more of the aforementioned preferred embodiments may be combined.

Methods and systems for designing an experiment using a computer to determine whether the experiment is a true experiment are described. These approaches allow a user who is unsophisticated in the complexities of true experimental design to design and deploy an experiment that produces substantially confound-free results and can be used to determine and quantify any causal relationship between independent and dependent variables. The computer may select one or more independent and/or dependent variables of the experiment or may assist the user in selection of independent and/or dependent variables. Formation of control and treatment groups, randomization and/or blocking to reduce the effects of confounding variables may be performed by the computer with or without input from the user.

摘要:
Methods and apparatus for facilitating the sharing of graphics rendering operation implementations between different pixel formats. A lookup table is generated that stores the descriptions of the various rendering operation implementations. A plurality of chains of inherited object descriptors allows traversal from specific to more general descriptions of pixel formats and composition operations. Using these chains, the lookup table can be searched for a rendering operation implementation that best matches the specified criteria.
摘要:
In a computer graphics windowing system including a color map, a method for managing palette color value contents of the color map. Input color values are received. Error values between each input color value and each palette color value are used to determine a closest palette color value to each input color value. A list of input color values having largest error value distances to their respective closest palette color values is determined. A subset of this list is added to the color map to derive a modified color map. A color value metric process for determining an error value between each input color value and each palette color value comprises converting each input color value and each palette color value to a uniform color space. A lightness weighting constant is used to skew the error value in to be more strongly influenced by differences in lightness than by differences in chromaticity. A look up table having address spaces indexed by RGB index color values is generated. Each address space of the look up table is filled with a color map address of the closest palette color value to the respective RGB index color value referencing the address space.
