    • Colored pigments having one or more desired parameters and/or properties are described. These parameters and/or properties include: a) a particles size of from about 10 nm to about 300 nm; b) an accusizer number of less than 1010 particles/ml of dispersion at 15% solids which are greater than 0.5 micron; c) a filterability such that when in a liquid medium, 100 ml having 10% solids of the colored pigment filters through a 3 micron nylon absolute filter; d) a colored pigment purity of greater than about 80%, based on extractable material; and/or e) a stability such that the above-described properties do not change by more than 50% at 25 degrees C for at least one week. Colored pigments having at least one organic group and having one or more of the above-described characteristics is also described as well as a process for preparing surface-modified colored pigments. The process involves combining at least one treating agent and at least one type of colored pigment(s) in a container to form a mixture and subjecting the mixture to high shearing and introducing at least one diazotizing agent to the mixture at least for a portion of time while the high shearing is taking place, and preferably during the entire time that high shearing is taking place, such that a reaction product is formed and contains surface-modified colored pigment(s).
    • 描述具有一个或多个所需参数和/或性质的有色颜料。 这些参数和/或性质包括:a)约10nm至约300nm的粒度; b)大于0.5微米的15%固体的小于1010个/ ml分散体的指示剂数; c)过滤性,使得当在液体介质中,具有10%固体的着色颜料的100ml通过3微米尼龙绝对过滤器过滤; d)基于可萃取材料的有色颜料纯度大于约80%; 和/或e)稳定性,使得上述性质在25℃下至少不超过50%变化至少一周。 还描述了具有至少一个有机基团并具有一种或多种上述特征的着色颜料以及制备表面改性着色颜料的方法。 该方法包括将至少一种处理剂和至少一种类型的有色颜料混合在容器中以形成混合物,并使混合物经受高剪切,并将至少一种重氮化试剂至少引入至少一部分 并且优选在高剪切发生的整个时间内形成反应产物并含有表面改性的着色颜料。

    • General-purpose distributed data-parallel computing using high-level computing languages is described. Data parallel portions of a sequential program written in a high-level language are automatically translated into a distributed execution plan. Map and reduction computations are automatically added to the plan. Patterns in the sequential program can be automatically identified to trigger map and reduction processing. Direct invocation of map and reduction processing is also provided. One or more portions of the reduce computation are pushed to the map stage and dynamic aggregation is inserted when possible. The system automatically identifies opportunities for partial reductions and aggregation, but also provides a set of extensions in a high-level computing language for the generation and optimization of the distributed execution plan. The extensions include annotations to declare functions suitable for these optimizations.
    • 描述了使用高级计算语言的通用分布式数据并行计算。 以高级语言编写的顺序程序的数据并行部分将自动转换为分布式执行计划。 地图和缩小计算将自动添加到计划中。 顺序程序中的模式可以自动识别,以触发地图和缩小处理。 还提供了直接调用地图和缩小处理。 减少计算的一个或多个部分被推送到地图阶段,并且尽可能地插入动态聚合。 系统自动识别部分缩减和聚合的机会,但也提供了一组用于生成和优化分布式执行计划的高级计算语言的扩展。 扩展包括用于声明适合这些优化的函数的注释。
